Further, opposed with fixation clip 11 along connecting rod 14 and movably arrange movable pressure plate 12 to mould opening and closing direction。For this, movable pressure plate 12 is fixed on guiding piece Gd, and position corresponding with connecting rod 14 in movable pressure plate 12 forms the not shown guide hole for making connecting rod 14 run through。It addition, guiding piece Gd also fixes adsorption plate 22 described later。

Further, fixation clip 11 is fixed cover half 15, movable pressure plate 12 is fixed dynamic model 16, along with the advance and retreat of movable pressure plate 12, cover half 15 and dynamic model 16 contact separation, carry out mold closing, matched moulds and die sinking。It addition, along with carrying out matched moulds, form not shown cavity space between cover half 15 and dynamic model 16, the not shown resin penetrated from the injection nozzle 18 of injection device 17 is filled in cavity space。It addition, constituted die device 19 by cover half 15 and dynamic model 16。

Adsorption plate 22 and movable pressure plate 12 are fixed on guiding piece Gd abreast。Thus, adsorption plate 22 is more more rearward than rear fender 13 free to advance or retreat。Adsorption plate 22 can be formed by magnetic material。Such as, adsorption plate 22 can include the electromagnetism stacked steel plate that formed by the thin plate that stacking is made up of ferromagnetic。

Line motor 28 is arranged on guiding piece Gd to make movable pressure plate 12 retreat。Line motor 28 possesses stator 29 and mover 31, and on framework Fr, parallel with guiding piece Gd and with movable pressure plate 12 moving range is correspondingly formed stator 29, opposed with stator 29 in the lower end of movable pressure plate 12 and throughout preset range formed mover 31。

Mover 31 possesses unshakable in one's determination 34 and coil 35。Further, unshakable in one's determination 34 possess towards stator 29 multiple magnetic pole tooths 33 that are prominent and that formed with preset space length, and coil 35 package is on each magnetic pole tooth 33。It addition, magnetic pole tooth 33 is formed as being parallel to each other on the direction vertical relative to the moving direction of movable pressure plate 12。Further, stator 29 possesses not shown iron core and the not shown permanent magnet extending on this iron core and being formed。This permanent magnet alternately and is formed by magnetic with the spacing identical with magnetic pole tooth 33 by making each magnetic pole of N pole and S pole。If driving line motor 28 by supplying scheduled current to coil 35, then mover 31 is retreated, as it does so, retreated by guiding piece Gd movable pressure plate 12, it is possible to carry out mold closing and die sinking。

It addition, in present embodiment, permanent magnet is disposed on stator 29, and coil 35 is disposed on mover 31, but also is able to be disposed on stator coil, and permanent magnet is disposed on mover。Now, coil will not be driven along with line motor 28 and be moved, therefore, it is possible to easily carry out the distribution for supplying electric power to coil。

It addition, be not limited to fix the structure of movable pressure plate 12 and adsorption plate 22 on guiding piece Gd, it is possible to be set to the structure being arranged at by the mover 31 of line motor 28 on movable pressure plate 12 or adsorption plate 22。Further, it is not limited to line motor 28 as mould switching mechanism, it is possible to for fluid pressure type or electrodynamic type etc.。

If before movable pressure plate 12 so dynamic model 16 abut against with cover half 15, then carry out mold closing, then, carry out matched moulds。Further, in order to carry out matched moulds, between rear fender 13 and adsorption plate 22, electromagnet unit 37 is arranged。Further, the center-pole 39 running through rear fender 13 and adsorption plate 22 and extension and link movable pressure plate 12 and adsorption plate 22 is movably arranged。This center-pole 39 when mold closing and during die sinking with the advance and retreat linkage of movable pressure plate 12 and make adsorption plate 22 retreat, and when matched moulds, the mold clamping force produced by electromagnet unit 37 is transferred to movable pressure plate 12。

It addition, constituted mold closing mechanism 10 by fixation clip 11, movable pressure plate 12, rear fender 13, adsorption plate 22, line motor 28, electromagnet unit 37 and center-pole 39 etc.。

Electromagnet unit 37 includes the electric magnet 49 being formed at rear fender 13 side and the adsorption section 51 being formed at adsorption plate 22 side。Further, it is formation groove 45 around center-pole 39 in the predetermined portions of rear end face of rear fender 13, present embodiment, is forming iron core (interior pole) 46 more in the inner part than groove 45, and than groove 45 more outward formation yoke (outer pole) 47。Further, in groove 45, around 46 package coils 48 unshakable in one's determination。It addition, the surface by connecting rod 14 side (rear magnetic yoke portion) forms aftermentioned keyway 47a in rear fender 13。Keyway 47a embeds built in items 90 described later。

It addition, in present embodiment, electric magnet 49 can be formed separately with rear fender 13, and be formed separately adsorption section 51 with adsorption plate 22, it is possible to electric magnet is formed as a part for rear fender 13, and adsorption section is formed as a part for adsorption plate 22。And, it is possible to contrary configuration electric magnet and adsorption section。Such as, electric magnet 49 can be set in adsorption plate 22 side, adsorption section is set in rear fender 13 side。

In electromagnet unit 37, if supplying electric current to coil 48, then adsorption section 51 is adsorbed by electric magnet 49 by driving, it is possible to produce mold clamping force。

Center-pole 39 is arranged to and links at rearward end and adsorption plate 22 and link with movable pressure plate 12 in leading section。Therefore, center-pole 39 is when mold closing and movable pressure plate 12 is together front and then makes adsorption plate 22 advance, and together retreats when die sinking with movable pressure plate 12 and make adsorption plate 22 retreat。For this, the middle body at rear fender 13 forms the corner apertures 41 for making center-pole 39 run through。It addition, when rear fender 13 is made up of electromagnetism stacked steel plate, the electromagnetism stacked steel plate of corner apertures 41 part can be formed (X1 with reference to Fig. 3) by splitting, or can form corner apertures 41 by processing after stacking。

The line motor 28 of mold closing mechanism 10 and the driving of electric magnet 49 is controlled by control portion 60。Control portion 60 possesses CPU and memorizer etc., is also equipped with the circuit for supplying electric current to the coil 35 of line motor 28 or the coil 48 of electric magnet 49 according to the result calculated by CPU。Control portion 60 is also connected with loading detection device 55。Loading detection device 55 is arranged at the precalculated position (precalculated position between fixation clip 11 and rear fender 13) of at least 1 connecting rod 14 in mold closing mechanism 10, and detection puts on the load of this connecting rod 14。Figure is shown with the example arranging loading detection device 55 in upper and lower 2 connecting rods 14。Loading detection device 55 is such as made up of the sensor of the elongation of detection connecting rod 14。The load detected by loading detection device 55 delivers to control portion 60。It addition, eliminate control portion 60 for convenience in fig. 2。

Then, the action of mold closing mechanism 10 is illustrated。

Mold closing operation is controlled by the mould opening and closing process portion 61 in control portion 60。Under the state (state during die sinking) of Fig. 2, mould opening and closing process portion 61 supplies electric current to coil 35。Then, by driving, movable pressure plate 12 advances line motor 28, as it is shown in figure 1, dynamic model 16 and cover half 15 abut against。Now, between rear fender 13 and adsorption plate 22, between electric magnet 49 and adsorption section 51, namely form gap delta。It addition, compared with mold clamping force, the power needed for mold closing fully diminishes。

Then, the matched moulds process portion 62 in control portion 60 controls matched moulds operation。Matched moulds process portion 62 supplies electric current to coil 48, by the absorption affinity of electric magnet 49, adsorption section 51 is adsorbed。As it does so, mold clamping force is transferred to movable pressure plate 12 through adsorption plate 22 and center-pole 39, thus carry out matched moulds。Mold clamping force is when changing when starting matched moulds etc., and matched moulds process portion 62 is controlled using by order to produce namely required as the mold clamping force of the target at steady state stabling current value supply of the mold clamping force becoming target that should obtain according to this change to coil 48。

It addition, mold clamping force is detected by loading detection device 55。The mold clamping force detected delivers to control portion 60, in control portion 60, adjusts to make mold clamping force become setting value and supplies the electric current to coil 48, and carry out feedback control。During this period, resin melted in injection device 17 penetrates from injection nozzle 18, and is filled in the cavity space of die device 19。

If the resin in cavity space cools down and solidifies, then mould opening and closing process portion 61 controls die sinking operation。When Fig. 1, matched moulds process portion 62 stops supplying electric current to coil 48。As it does so, line motor 28 by driving, movable pressure plate 12 retreats, as in figure 2 it is shown, dynamic model 16 is placed in retrogressing restraining position, carry out die sinking。

It addition, in the example in the figures, the rear side of adsorption plate 22 is provided with mould thickness guiding mechanism 44。Mould thickness guiding mechanism 44 is the mechanism that adjusts gap delta corresponding to the thickness of die device 19。Such as, mould thickness guiding mechanism 44 can change the position of center-pole 39 relative adsorption plate 22 by not shown mould thickness adjustment motor。Thereby, it is possible to adjust the position of center-pole 39 relative adsorption plate 22, and adjust adsorption plate 22 and be relatively fixed pressing plate 11 and the position of movable pressure plate 12, gap delta is set to optimum。That is, mould thickness adjustment is carried out by the relative position of change movable pressure plate 12 with adsorption plate 22。

At this, with reference to the part that Fig. 3 is later, inventive feature structure is illustrated。

Fig. 3 indicates that the axonometric chart of the rear fender 13 based on one embodiment of the invention (embodiment 1)。Fig. 4 represents that several major section of rear fender 13, Fig. 4 (A) are the sectional views of the line A-A along Fig. 3, and Fig. 4 (B) is the sectional view of the line B-B along Fig. 3, and Fig. 4 (C) is the sectional view of the line C-C along Fig. 3。Fig. 5 indicates that the figure of the example of other shapes of keyway 47a。It addition, in Fig. 3 and Fig. 4, arrow h, arrow V represent the left and right directions (horizontal direction) of rear fender 13, above-below direction (vertical direction) respectively。But, owing to these directions change according to the state that arranges (direction) of injection (mo(u)lding) machine, so being for convenience's sake eventually。It addition, arrow f represents the front of rear fender 13。

Rear fender 13 can be made up of electromagnetism stacked steel plate。It addition, electromagnetism stacked steel plate can be formed by the thin plate (steel plate) being made up of ferromagnetic through insulating barrier stacking。Or, electromagnetism stacked steel plate can have the steel plate of insulating barrier to be formed by stratification。In the example shown in Fig. 3, steel plate is along left and right directions (arrow h) stacking of rear fender 13。Rear fender 13 is formed also by by multiple electromagnetism stacked steel plate integrations。Such as, in the example shown in Fig. 3, rear fender 13 is by constituting 4 electromagnetism stacked steel plate integrations of 2 line X1 segmentations of the above-below direction set by corresponding corner apertures 41。It addition, quantity or segmentation form (segmentation direction etc.) for integrated electromagnetism stacked steel plate are any。Such as, in the example shown in Fig. 3, it is divided into above-below direction (arrow V), but also may be partitioned into left and right directions (arrow h)。So when multiple electromagnetism stacked steel plate integrations are formed rear fender 13, it is possible to composition is difficult to the rear fender 13 of the relatively larger volume being made up of 1 stacked steel plate。It addition, multiple electromagnetism stacked steel plate are by the integration of aftermentioned built in items 90。

As it is shown on figure 3, the pattern of rectangular shape forms groove 45 when the rear end face of rear fender 13 is with right-angle view。It addition, by groove 45 around the protuberance of inner side form unshakable in one's determination 46。

As shown in Figures 3 and 4, the front end face of rear fender 13 is formed with keyway 47a。Keyway 47a also can extend along any direction, but the form preferably extended with the stacked direction along electromagnetism stacked steel plate from the viewpoint of manufacturing is formed。That is, the form that keyway 47a preferably extends with the direction that the steel plate along relative electromagnetism stacked steel plate is vertical is formed。As shown in Figures 3 and 4, keyway 47a can also uiform section straight-line extension。

In the example shown in Fig. 3, the cross sectional shape of keyway 47a is trapezoidal (wedge shape) that entrance side (face side) becomes minor face, and now, the face corresponding with trapezoidal hypotenuse constitutes fastener 47b(with reference to Fig. 4 (A))。It addition, the width that the cross sectional shape of keyway 47a is bottom side has the form of fastener 47b wider than entrance side, it is arbitrary。Such as, as shown in Fig. 5 (A), keyway 47a can for bottom side broaden T-shaped, as shown in Figure 5 (B), it is also possible to for the L-shaped that bottom side broadens。

Fig. 6 indicates that the axonometric chart of an example of the built in items 90 of the keyway 47a being embedded in the rear fender 13 shown in Fig. 3。

Built in items 90 is formed by the material that the intensity/rigidity of such as metal etc is higher。Built in items 90 has the keyway 47a of relative rear fender 13 shape actually embedded in gapless mode。That is, the cross sectional shape of built in items 90 is corresponding with the cross sectional shape of keyway 47a。That is, in the example in the figures, the cross sectional shape of built in items 90 is trapezoidal (wedge shape)。But, in order to carry out slidingtype embedding described later, the cross sectional shape of built in items 90 can be the shape (such as reduced similar shape) of the cross sectional shape being slightly smaller than keyway 47a。Further, built in items 90 preferably extends with the length with the same length of the long side direction (arrow h) of keyway 47a。

Built in items 90 embeds the keyway 47a of rear fender 13 slidably from the end side insertion of the left and right directions of rear fender 13。Now, built in items 90 is mountable to be shaped to the electromagnetism stacked steel plate of reservation shape。When such as rear fender 13 as above-mentioned be made up of multiple electromagnetism stacked steel plate time, insert built in items 90 at the keyway 47a corresponding to multiple electromagnetism stacked steel plate。Now, built in items 90 can play the positioning function between multiple electromagnetism stacked steel plate。That is, multiple electromagnetism stacked steel plate can through built in items 90 mutually with the integration of intended position relationship。Further, owing to built in items 90 is incorporated into connecting rod 14, therefore multiple electromagnetism stacked steel plate can through the relative connecting rod 14 of built in items 90 with the integration of intended position relationship。It addition, the electromagnetism stacked steel plate constituting rear fender 13 is integrated after each steel plate also can be installed on built in items 90。Now, for instance even if when rear fender 13 is made up of 1 electromagnetism stacked steel plate, built in items 90 also is able to play the function that each steel plate is positioned。

As it is shown in fig. 7, in conjunction with connecting rod 14 on built in items 90。This combining form can be any form including bolt combination etc.。Therefore, rear fender 13 through built in items 90 in conjunction with connecting rod 14。In other words, rear fender 13 is attracting direction to hang through built in items 90 by connecting rod 14。Thereby, it is possible to reduce the shearing force or bending stress that likely produce in rear fender 13。

But, when matched moulds operation owing to adsorption section 51 is adsorbed by rear fender 13, so rear fender 13 bears its counteracting force, represent with arrow P in Fig. 7, bear tensile force。The relative rear fender 13 of this tensile force works towards the direction extracted from the built in items 90 being incorporated into connecting rod 14。If according to the present embodiment, in the above-mentioned keyway 47a with fastener 47b, it is embedded with built in items 90, so this point is prevented from rear fender 13 and extracts from built in items 90。

Fig. 8 indicates that the figure of an example of the anticreep sheet material 92 on the end face being mountable to rear fender 13。

As shown in Figure 8, the end face of the left and right directions (arrow h) of rear fender 13 can be provided with the anticreep sheet material 92 preventing built in items 90 from coming off in the lateral direction from rear fender 13。Anticreep sheet material 92 is fixed on rear fender 13(electromagnetism stacked steel plate also by welding etc.)。Anticreep sheet material 92 plays the opening of the left and right directions of the keyway 47a of blocking rear fender 13 and prevents the function that built in items 90 comes off in the lateral direction from rear fender 13。It addition, in the example in the figures, anticreep sheet material 92 has the shape identical with the steel plate of the end face of the left and right directions constituting rear fender 13, but if at least the keyway 47a of local stoppages rear fender 13 plays the sheet material of above-mentioned anti-drop function, then can have any shape。It addition, in the example in the figures, anticreep sheet material 92 is arranged at the both ends of the surface of the left and right directions of rear fender 13, but also can be only arranged at the end face of a side。Now, it is preferable that built in items 90 is relatively only arranged at the anticreep sheet material 92 of the end face of a side and fixes。

Fig. 9 indicates that the axonometric chart of the rear fender 130 of other embodiments (embodiment 2) based on the present invention。Figure 10 represents that several major section of rear fender 130, Figure 10 (A) are the sectional views of the line A-A along Fig. 9, and Figure 10 (B) is the sectional view of the line B-B along Fig. 9, and Figure 10 (C) is the sectional view of the line C-C along Fig. 9。

Based on the rear fender 130 of the present embodiment 2 with above-mentioned based on compared with the rear fender 13 of embodiment 1, main difference is in that extremely to carry out multipolarization by forming 2。Hereinafter, only illustrate with the difference from above-described embodiment 1 for main, about the structure identical with above-described embodiment 1 can adding same reference marks and omit the description。

In example shown in Fig. 9, in rear fender 130, hold 2 groups of groove 45A and groove 45B of coil (not shown) corresponding with multipolarization (2 polarize) and be formed as rectangular-shaped when observing with top view respectively。It addition, each protuberance of the inner side surrounded formed by groove 45A and groove 45B forms 2 groups of iron core 46A and 46B unshakable in one's determination。But, being patterned into of groove 45A and groove 45B is varied, and number of poles is also any。

Figure 13 indicates that the sectional view of the major part of the rear fender 131 of other embodiments (embodiment 3) based on the present invention。It addition, the content of the present embodiment applies also in adsorption plate 22。

As shown in figure 13, built in items 90 has the stream hole 91 of temperature adjustable fluid。Built in items 90 is run through in stream hole 91, and extends parallel to the stacked direction of electromagnetism stacked steel plate。Temperature adjustable fluid, in the internal flow of built in items 90, therefore becomes different during stream from the through hole running through electromagnetism stacked steel plate along its stacked direction, and temperature adjustable fluid will not spill each other from steel plate。Further, temperature adjustable fluid does not directly contact with electromagnetism stacked steel plate, it is possible to prevent electromagnetism stacking steel plate corrosion。

Temperature adjustable fluid and electromagnetism stacked steel plate carry out heat exchange and electromagnetism stacked steel plate are carried out homoiothermic。Temperature adjustable fluid is the cooling coolant such as water or air。Coolant suppresses the coil 48 of electric magnet 49 overheated by cooling down electromagnetism stacked steel plate。It addition, temperature adjustable fluid is alternatively the heating agents such as warm water。

It addition, when rear fender 131 has multiple built in items 90, at least form stream hole 91 at 1 built in items 90。

Built in items 90 is inserted in the keyway 47a of electromagnetism stacked steel plate, for instance be fixed on keyway 47a with shrink-fit or shrink fit。

In shrink-fit, such as, cooling down built in items 90 with the coolant such as dry ice or liquid nitrogen and making, on its basis shunk, to be inserted in the keyway 47a of electromagnetism stacked steel plate of (such as room temperature) more at higher temperature than built in items 90。Afterwards, if the temperature of built in items 90 returns to room temperature, then built in items 90 expands, and the outer wall of built in items 90 is by the inner wall tightening of keyway 47a。

In shrink fit, electromagnetism stacked steel plate is heated and increase electromagnetism stacked steel plate keyway 47a sectional area basis on, will insert in keyway 47a than the built in items 90 of electromagnetism stacked steel plate more low temperature (such as room temperature)。Afterwards, if the temperature of electromagnetism stacked steel plate returns to room temperature, then the sectional area of keyway 47a diminishes, by the inner wall tightening built in items 90 of keyway 47a。

Gap between inwall and the outer wall of built in items 90 of keyway 47a diminishes because of shrink-fit or shrink fit, and thermal contact resistance declines, and therefore the homoiothermic efficiency of electromagnetism stacked steel plate becomes good。

As the sheet metal 93 of heat transfer component between the inwall and the outer wall of built in items 90 of keyway 47a。The hardness low (softness) of preferred sheet metal 93 is in the hardness of built in items 90。The hardness of sheet metal 93 was measured by impressing hardness test before shrink-fit or shrink fit。As impressing hardness test such as available Brinell hardness test method (JISZ2243)。Such as, when the metal forming built in items 90 is rustless steel, as the available copper (Cu) of metal of sheet metal 93, aluminum (Al), stannum (Sn), plumbous (Pb), silver (Ag), indium (In) or the alloy comprising these central any more than 1 kinds。Consider to be especially suitable for utilizing indium or indium alloy from the viewpoint of pliability and cost。

In shrink-fit, sheet metal 93 is wrapped on the outer wall of built in items 90, and sheet metal 93 and built in items 90 are inserted in the keyway 47a of electromagnetism stacked steel plate。In shrink-fit, before inserting keyway 47a, cool down at least any one party of built in items 90 and sheet metal 93 with coolant。

Such as, when only cooling down built in items 90 with coolant before inserting keyway 47a, after inserting keyway 47a, the temperature of built in items 90 returns to room temperature, the outer wall of the inwall of keyway 47a and built in items 90 clamp sheet metal 93, become relatively thin。The deformation of sheet metal 93 can be elastic deformation, it is also possible to for plastic deformation。Sheet metal 93 is formed by the metal more soft than built in items 90, so the deviation in the gap between being deformed into the inwall and the outer wall of built in items 90 that absorb keyway 47a is to fill up gap, and is adjacent on the inwall of keyway 47a with the outer wall of built in items 90。

Additionally, before inserting keyway 47a, only cool down sheet metal 93 with coolant, and when making the lower thickness of sheet metal 93, after inserting keyway 47a, the temperature of sheet metal 93 returns to room temperature, the thickness of sheet metal 93 is thickening, the outer wall of the inwall of keyway 47a and built in items 90 clamp sheet metal 93。The deviation in the gap that sheet metal 93 is deformed between the inwall and the outer wall of built in items 90 that absorb keyway 47a is to fill up gap, and is adjacent on the inwall of keyway 47a with the outer wall of built in items 90。

In shrink fit, sheet metal 93 is wrapped on the outer wall of built in items 90, and in the keyway 47a of the electromagnetism stacked steel plate heated, inserts sheet metal 93 and built in items 90。Afterwards, if the temperature of electromagnetism stacked steel plate returns to room temperature, then the sectional area of keyway 47a diminishes, the outer wall of the inwall of keyway 47a and built in items 90 clamp sheet metal 93。The deviation in the gap that sheet metal 93 is deformed between the inwall and the outer wall of built in items 90 that absorb keyway 47a is to fill up gap, and is adjacent on the inwall of keyway 47a with the outer wall of built in items 90。

So, no matter being shrink-fit or shrink fit, the deviation in the gap that sheet metal 93 is all deformed between the inwall and the outer wall of built in items 90 that absorb keyway 47a is to fill up gap, and is adjacent on the inwall of keyway 47a with the outer wall of built in items 90。Thus, thermal contact resistance declines further, and the homoiothermic efficiency of electromagnetism stacked steel plate becomes better。Further, when absorbing the deviation in above-mentioned gap, owing to soft sheet metal 93 can be suppressed optionally to deform, harder built in items 90 local deformation, therefore can reduce the damage of built in items 90。

It addition, the heat transfer component of Figure 13 is formed by metal, but there is the thermal conductivity higher than air, also can by resin formation。Further, heat transfer component is lamellar, but can also be ring-type。

It addition, the built in items 90 of Figure 13 is fixed on keyway 47a with shrink-fit or shrink fit, but this fixing means is not limited to shrink-fit and shrink fit。Such as there is insertion built in items 90 in keyway 47a, make the molten resin heated flow into the gap between inwall and the outer wall of built in items 90 of keyway 47a the method etc. of cooling curing molten resin。Now, as between the resin bed of heat transfer component inwall and the outer wall of built in items 90 between keyway 47a。The hardness of resin bed is lower than the hardness of built in items 90。

It addition, in Figure 13, heat transfer component is between the inwall and the outer wall of built in items 90 of keyway 47a, but can also not have heat transfer component。That is, the outer wall of the inwall of keyway 47a and built in items 90 also by shrink-fit or shrink fit directly against。

Figure 14 indicates that the figure of the variation of Figure 13。In Figure 14, the structure additional same symbol identical with Figure 13 is omitted the description。

Being formed with stream hole 91 at built in items 90 in Figure 13, on the contrary, be formed with the flow passage groove 95 of temperature adjustable fluid in Figure 14 at the front end face of built in items 90, the front end face of built in items 90 is fixed with cover 97, different in this。

Cover 97 is fixed on built in items 90 with bolt etc.。The seal member preventing temperature adjustable fluid from spilling is clamped between built in items 90 and cover 97。It addition, cover 97 and the fixing of built in items 90 and built in items 13 insert in the order of keyway 47a any one before can。

Connecting rod 14 is fixed on cover 97。

It addition, when rear fender has multiple built in items 90, at least 1 built in items 90 forms flow passage groove 95。

Strengthening part 98 is formed the stream hole 99 of temperature adjustable fluid。The stacked direction of stream hole 99 and electromagnetism stacked steel plate extends parallel to。Owing to temperature adjustable fluid is in the internal flow of strengthening part 98, therefore becoming different during stream from the through hole running through electromagnetism stacked steel plate to stacked direction, temperature adjustable fluid will not spill each other from steel plate。Further, owing to temperature adjustable fluid does not directly contact with electromagnetism stacked steel plate, therefore, it is possible to prevent electromagnetism stacking steel plate corrosion。

Temperature adjustable fluid and electromagnetism stacked steel plate carry out heat exchange and electromagnetism stacked steel plate are carried out homoiothermic。Temperature adjustable fluid is the cooling coolant such as water or air。Coolant suppresses the coil 48 of electric magnet 49 overheated by cooling down electromagnetism stacked steel plate。In order to improve cooling effectiveness, temperature adjustable fluid can also be the heating agents such as warm water。

Connecting rod 14 also can be fixed at the fixing strengthening part 98 of the front end face of electromagnetism stacked steel plate with bolt etc.。

It addition, in Figure 15, strengthening part 98 is formed with stream hole 99, but identical with Figure 14, it is possible on strengthening part 98, to be formed with the flow passage groove of temperature adjustable fluid, and at the fixing cover in the face of the flow passage groove forming strengthening part 98。

It addition, the stream of the temperature adjustable fluid of the present embodiment (stream hole, flow passage groove) is formed on strengthening part 98, but such as also can be formed on supporting parts 44b shown in the connecting member 94 shown in Figure 11, Figure 12 etc.。

It addition, when rear fender has multiple strengthening part 98, at least 1 strengthening part 98 forms stream hole or flow passage groove。

Figure 16 indicates that the sectional view of the major part of the rear fender 133 of another other embodiment (embodiment 5) based on the present invention。In Figure 16, the structure additional same symbol identical with Figure 13 (embodiment 3) is omitted the description。It addition, the content of the present embodiment also apply be applicable to adsorption plate 22。

As shown in figure 16, built in items 90 is formed the insertion hole 72 as the insertion section inserting flow channel tube 71。Flow channel tube 71 runs through built in items 90。Each built in items 90 respectively arranges 1 flow channel tube 71, but may also set up a plurality of。It addition, when rear fender 133 has multiple built in items 90, insert flow channel tube 71 in the insertion section of at least 1 built in items 90。

Flow channel tube 71 is such as cylindrical duct, has the stream of temperature adjustable fluid in inside。Owing to temperature adjustable fluid is in the internal flow of flow channel tube 71, and temperature adjustable fluid does not directly contact with built in items 90, therefore, it is possible to prevent built in items 90 from corroding。

Temperature adjustable fluid and rear fender 133 carry out heat exchange and rear fender 133 are carried out homoiothermic。Temperature adjustable fluid is the cooling coolant such as water or air。Coolant suppresses the coil 48 of electric magnet 49 overheated by cooling down rear fender 133。It addition, temperature adjustable fluid is alternatively the heating agents such as warm water。

Flow channel tube 71 is inserted in the insertion hole 72 of built in items 90, for instance be fixed on insertion hole 72 with shrink-fit or shrink fit。Flow channel tube 71 at fixing in the keyway 47a of electromagnetism stacked steel plate of the fixing and built in items 90 inserted in hole 72 of built in items 90, its any one before can, it is also possible to carry out simultaneously。

In shrink-fit, with the coolant cooling flowing path pipe such as dry ice or liquid nitrogen 71, and reduce on the basis of external diameter of flow channel tube 71, flow channel tube 71 is inserted in the insertion hole 72 of built in items 90 of (such as room temperature) more at higher temperature than flow channel tube 71。Afterwards, if the temperature of flow channel tube 71 returns to room temperature, then flow channel tube 71 expands, and the outer wall of flow channel tube 71 is inserted into the inner wall tightening in hole 72。

In shrink fit, built in items 90 is heated and increase built in items 90 insert hole 72 diameter basis on, will than the flow channel tube 71 of built in items 90 more low temperature (such as room temperature) be inserted in insertion hole 72 in。Afterwards, if the temperature of built in items 90 returns to room temperature, then the diameter inserting hole 72 reduces, by the outer wall of the inner wall tightening flow channel tube 71 inserting hole 72。

Gap between inwall and the outer wall of flow channel tube 71 in insertion hole 72 diminishes because of shrink-fit or shrink fit, and thermal contact resistance declines, and therefore the homoiothermic efficiency of rear fender 133 becomes good。Flow channel tube 71 is made up of cylindrical duct, inserts hole 72 and has circular section shape, in order to is fastened the outer wall of flow channel tube 71 by shrink-fit or shrink fit equably。

As heat transfer component sheet metal 73 between built in items 90 insert hole 72 inwall and the outer wall of flow channel tube 71 between。The hardness low (softness) of preferred sheet metal 73 is in the hardness of flow channel tube 71。

In shrink-fit, sheet metal 73 is wrapped on the outer wall of flow channel tube 71, and sheet metal 73 and flow channel tube 71 is inserted in the insertion hole 72 of built in items 90。In shrink-fit, before being inserted in insertion hole 72, by least any one party of coolant cooling flowing path pipe 71 and sheet metal 73。

Such as, when when being inserted in before insertion hole 72 with coolant cooling flowing path pipe 71, being inserted in the temperature of flow channel tube 71 after inserting hole 72 and return to room temperature, flow channel tube 71 expands, the outer wall of the inwall with flow channel tube 71 that insert hole 72 clamp sheet metal 73, become relatively thin。The deformation of sheet metal 73 can be elastic deformation, it is also possible to for plastic deformation。Sheet metal 73 is formed by the metal more soft than flow channel tube 71, so the deviation in the gap between being deformed into the inwall and the outer wall of flow channel tube 71 that absorb insertion hole 72 is to fill up gap, and is adjacent on the outer wall of the inwall with flow channel tube 71 that insert hole 72。

Additionally, when only cooling down sheet metal 73 before being inserted in insertion hole 72 with coolant and make the lower thickness of sheet metal 73, being inserted in the temperature of sheet metal 73 after inserting hole 72 and return to room temperature, the thickness of sheet metal 73 is thickening, the outer wall of the inwall and flow channel tube 71 that insert hole 72 clamp sheet metal 73。Sheet metal 73 is deformed into the deviation in the gap absorbed between the inwall and the outer wall of flow channel tube 71 that insert hole 72 to fill up gap, and is adjacent on the outer wall of the inwall with flow channel tube 71 that insert hole 72。

In shrink fit, sheet metal 73 is wrapped on the outer wall of flow channel tube 71, and in the insertion hole 72 of the built in items 90 heated, inserts sheet metal 73 and flow channel tube 71。Afterwards, if the temperature of built in items 90 returns to room temperature, then the diameter inserting hole 72 reduces, the outer wall of the inwall and flow channel tube 71 that insert hole 72 clamp sheet metal 73。Sheet metal 73 is deformed into the deviation in the gap absorbed between the inwall and the outer wall of flow channel tube 71 that insert hole 72 to fill up gap, and is adjacent on the outer wall of the inwall with flow channel tube 71 that insert hole 72。

So, no matter being shrink-fit or shrink fit, sheet metal 73 is all deformed into the deviation in the gap absorbed between the inwall and the outer wall of flow channel tube 71 that insert hole 72 to fill up gap, and is adjacent on the outer wall of the inwall with flow channel tube 71 that insert hole 72。Thus, thermal contact resistance reduces further, and the homoiothermic efficiency of rear fender 133 becomes better。Further, when absorbing the deviation in above-mentioned gap, owing to soft sheet metal 73 can be suppressed optionally to deform, harder flow channel tube 71 local deformation, therefore can reduce the damage of flow channel tube 71。

It addition, the heat transfer component of the present embodiment is formed by metal, but there is the thermal conductivity higher than air, also can by resin formation。Further, heat transfer component is lamellar, but can also be ring-type。

It addition, the flow channel tube 71 of the present embodiment is fixed on insertion hole 72 with shrink-fit or shrink fit, but this fixing means is not limited to shrink-fit and shrink fit。Such as have in inserting hole 72, insert flow channel tube 71, make the molten resin heated flow into the gap between the inwall and the outer wall of flow channel tube 71 that insert hole 72 method etc. of cooling curing molten resin。Now, as the resin bed of heat transfer component between the inwall and the outer wall of flow channel tube 71 that insert hole 72。The hardness of resin bed is lower than the hardness of flow channel tube 71。

It addition, in the present embodiment, heat transfer component is between the inwall and the outer wall of flow channel tube 71 that insert hole 72, but can also not have heat transfer component。That is, insert hole 72 inwall and flow channel tube 71 outer wall also by shrink-fit or shrink fit directly against。

Figure 17 indicates that the sectional view of the major part of the rear fender 134 of another other embodiment (embodiment 6) based on the present invention。In Figure 17, omit the description about the additional same symbol of structure identical with Figure 13 (embodiment 3)。It addition, the content of the present embodiment applies also for adsorption plate 22。

As shown in figure 17, built in items 90 is formed the insertion groove 76 as the insertion section inserting flow channel tube 75。Flow channel tube 75 runs through built in items 90。Each built in items 90 respectively arranges 1 flow channel tube 75, but may also set up a plurality of。It addition, when rear fender 134 has a plurality of built in items 90, insert flow channel tube 75 in the insertion section of at least 1 built in items 90。

Flow channel tube 75 is such as angle bobbin, has the stream of temperature adjustable fluid in inside。Owing to temperature adjustable fluid is in the internal flow of flow channel tube 75, and temperature adjustable fluid does not directly contact with built in items 90, therefore, it is possible to prevent built in items 90 from corroding。

Temperature adjustable fluid and rear fender 134 carry out heat exchange and rear fender 134 are carried out homoiothermic。Temperature adjustable fluid is the cooling coolant such as water or air。Coolant suppresses the coil 48 of electric magnet 49 overheated by cooling down rear fender 134。It addition, temperature adjustable fluid is alternatively the heating agents such as warm water。

Flow channel tube 75 is inserted in the insertion groove 76 of built in items 90, for instance can be fixed on insertion groove 76 by shrink-fit or shrink fit。Fixing in the keyway 47a of electromagnetism stacked steel plate of the flow channel tube 75 fixing and built in items 90 in the insertion groove 76 of built in items 90, its any one before can, it is also possible to carry out simultaneously。

In shrink-fit, with the coolant cooling flowing path pipe such as dry ice or liquid nitrogen 75 and make, on its basis reduced, to be inserted in by flow channel tube 75 in the insertion groove 76 of built in items 90 of (such as room temperature) more at higher temperature than flow channel tube 75。Afterwards, if the temperature of flow channel tube 75 returns to room temperature, then flow channel tube 75 expands, and the outer wall of flow channel tube 75 is by mutually opposing inwall (sidewall) fastening of the rectangular-shaped insertion groove 193 in cross section。

In shrink fit, on basis built in items 90 being heated and being widened the groove width of insertion groove 76 of built in items 90, will be inserted in insertion groove 76 than the flow channel tube 75 of built in items 90 more low temperature (such as room temperature)。Afterwards, if the temperature of built in items 90 returns to room temperature, then the groove width of insertion groove 76 becomes narrow, by the outer wall of the mutually opposing inner wall tightening flow channel tube 75 that cross section is rectangular-shaped insertion groove 76。

Gap between inwall and the outer wall of flow channel tube 75 of insertion groove 76 diminishes because of shrink-fit or shrink fit, and thermal contact resistance reduces, and therefore the homoiothermic efficiency of rear fender 134 becomes good。

As the sheet metal 77 of heat transfer component between the inwall and the outer wall of flow channel tube 75 of the insertion groove 76 of built in items 90。The hardness low (softness) of preferred sheet metal 77 is in the hardness of flow channel tube 75。

In shrink-fit, sheet metal 77 is wrapped on the outer wall of flow channel tube 75, and sheet metal 77 and flow channel tube 75 are inserted in the insertion groove 76 of built in items 90。In shrink-fit, before being inserted in insertion groove 76, by least any one party of coolant cooling flowing path pipe 75 and sheet metal 77。

Such as, when when being inserted in before insertion groove 76 with coolant cooling flowing path pipe 75, after being inserted in insertion groove 76, the temperature of flow channel tube 75 returns to room temperature, and flow channel tube 75 expands, the outer wall of the inwall of insertion groove 76 Yu flow channel tube 75 clamp sheet metal 77, becomes relatively thin。The deformation of sheet metal 77 can also be able to be plastic deformation for elastic deformation。Sheet metal 77 is formed by the metal more soft than flow channel tube 75, so the deviation in the gap between being deformed into the inwall and the outer wall of flow channel tube 75 that absorb insertion groove 76 is to fill up gap, and is adjacent on the inwall of insertion groove 76 with the outer wall of flow channel tube 75。

Additionally, when only cooling down sheet metal 77 before being inserted in insertion groove 76 with coolant and make the lower thickness of sheet metal 77, after being inserted in insertion groove 76, the temperature of sheet metal 77 returns to room temperature, and the thickness of sheet metal 77 is thickening, the outer wall of the inwall of insertion groove 76 and flow channel tube 75 clamp sheet metal 77。The deviation in the gap that sheet metal 77 is deformed between the inwall and the outer wall of flow channel tube 75 that absorb insertion groove 76 is to fill up gap, and is adjacent on the inwall of insertion groove 76 with the outer wall of flow channel tube 75。

In shrink fit, sheet metal 77 is wrapped in the outer wall of flow channel tube 75, and in the insertion groove 76 of the built in items 90 heated, inserts sheet metal 77 and flow channel tube 75。Afterwards, if the temperature of built in items 90 returns to room temperature, then the groove width of insertion groove 76 becomes narrow, the outer wall of the inwall of insertion groove 76 and flow channel tube 75 clamp sheet metal 77。The deviation in the gap that sheet metal 77 is deformed between the inwall and the outer wall of flow channel tube 75 that absorb insertion groove 76 is to fill up gap, and is adjacent on the inwall of insertion groove 76 with the outer wall of flow channel tube 75。

So, no matter being shrink-fit or shrink fit, the deviation in the gap that sheet metal 77 is all deformed between the inwall and the outer wall of flow channel tube 75 that absorb insertion groove 76 is to fill up gap, and is adjacent on the inwall of insertion groove 76 with the outer wall of flow channel tube 75。Thus, thermal contact resistance reduces further, and the homoiothermic efficiency of rear fender 134 becomes better。Further, when absorbing the deviation in above-mentioned gap, owing to soft sheet metal 77 can be suppressed optionally to deform, harder flow channel tube 75 local deformation, therefore can reduce the damage of flow channel tube 75。

It addition, the flow channel tube 75 of the present embodiment is fixed on insertion groove 76 with shrink-fit or shrink fit, but this fixing means is not limited to shrink-fit and shrink fit。Such as there is insertion flow channel tube 75 in insertion groove 76, make the molten resin heated flow into the gap between inwall and the outer wall of flow channel tube 75 of insertion groove 76 method etc. of cooling curing molten resin。Now, as between the resin bed of heat transfer component inwall and the outer wall of flow channel tube 75 between insertion groove 76。The hardness of resin bed is lower than the hardness of flow channel tube 75。

It addition, in the present embodiment, heat transfer component is between the inwall and the outer wall of flow channel tube 75 of insertion groove 76, but can also not have heat transfer component。That is, the outer wall of the inwall of insertion groove 76 and flow channel tube 75 also by shrink-fit or shrink fit directly against。

Figure 18 indicates that the sectional view of the major part of the rear fender 135 of another other embodiment (embodiment 7) based on the present invention。In Figure 18, omit the description about the additional same symbol of structure identical with Figure 15 (embodiment 4)。It addition, the content of the present embodiment applies also for adsorption plate 22。Further, the content of the present embodiment applies also in supporting parts 44b shown in the connecting member 94 shown in Figure 11, Figure 12 etc.。

As shown in figure 18, strengthening part 98 is formed the insertion hole 82 as the insertion section inserting flow channel tube 81。Flow channel tube 81 can run through strengthening part 98。Each strengthening part 98 respectively arranges 1 flow channel tube 81, it is possible to arrange a plurality of。It addition, when rear fender 135 has multiple strengthening part 98, insert flow channel tube 81 in the insertion section of at least 1 strengthening part 98。

Flow channel tube 81 is such as cylindrical duct, has the stream of temperature adjustable fluid in inside。Temperature adjustable fluid is in the internal flow of flow channel tube 81, and temperature adjustable fluid does not directly contact with strengthening part 98, therefore, it is possible to prevent the corrosion of strengthening part 98。

Temperature adjustable fluid and rear fender 135 carry out heat exchange and rear fender 135 are carried out homoiothermic。Temperature adjustable fluid is the cooling coolant such as water or air。Coolant suppresses the coil 48 of electric magnet 49 overheated by cooling down rear fender 135。It addition, temperature adjustable fluid is alternatively the heating agents such as warm water。

Flow channel tube 81 is inserted in the insertion hole 82 of strengthening part 98, for instance can be fixed on insertion hole 82 by shrink-fit or shrink fit。Any one in the fixing of the fixing electromagnetism stacked steel plate relative to strengthening part 98 inserted in hole 82 of strengthening part 98 of flow channel tube 81 before can。

In shrink-fit, with the coolant cooling flowing path pipe such as dry ice or liquid nitrogen 81, and reduce on the basis of external diameter of flow channel tube 81, flow channel tube 81 is inserted in the insertion hole 82 of strengthening part 98 of (such as room temperature) more at higher temperature than flow channel tube 81。Afterwards, if the temperature of flow channel tube 81 returns to room temperature, then flow channel tube 81 expands, and the outer wall of flow channel tube 81 is inserted into the inner wall tightening in hole 82。

In shrink fit, strengthening part 98 is heated and increase strengthening part 98 insert hole 82 diameter basis on, will than the flow channel tube 81 of strengthening part 98 more low temperature (such as room temperature) be inserted in insertion hole 82 in。Afterwards, if the temperature of strengthening part 98 returns to room temperature, then the diameter inserting hole 82 reduces, by the outer wall of the inner wall tightening flow channel tube 81 inserting hole 82。

Gap between inwall and the outer wall of flow channel tube 81 in insertion hole 82 diminishes because of shrink-fit or shrink fit, and thermal contact resistance reduces, and therefore the homoiothermic efficiency of rear fender 135 becomes good。Flow channel tube 81 is made up of cylindrical duct, inserts hole 82 and has circular section shape, in order to is fastened the outer wall of flow channel tube 81 by shrink-fit or shrink fit equably。

As heat transfer component sheet metal 83 between strengthening part 98 insert hole 82 inwall and the outer wall of flow channel tube 81 between。The hardness low (softness) of preferred sheet metal 83 is in the hardness of flow channel tube 81。

In shrink-fit, sheet metal 83 is wrapped on the outer wall of flow channel tube 81, and sheet metal 83 and flow channel tube 81 is inserted in the insertion hole 82 of strengthening part 98。In shrink-fit, before being inserted in insertion hole 82, by least any one party of coolant cooling flowing path pipe 81 and sheet metal 83。

Such as, when when being inserted in before insertion hole 82 with coolant cooling flowing path pipe 81, being inserted in the temperature of flow channel tube 81 after inserting hole 82 and return to room temperature, flow channel tube 81 expands, the outer wall of the inwall with flow channel tube 81 that insert hole 82 clamp sheet metal 83, become relatively thin。The deformation of sheet metal 83 can also be able to be plastic deformation for elastic deformation。Sheet metal 83 is formed by the metal more soft than flow channel tube 81, so the deviation in the gap between being deformed into the inwall and the outer wall of flow channel tube 81 that absorb insertion hole 82 is to fill up gap, and is adjacent on the outer wall of the inwall with flow channel tube 81 that insert hole 82。

Additionally, when only cooling down sheet metal 83 before being inserted in insertion hole 82 with coolant and make the lower thickness of sheet metal 83, after being inserted in insertion hole 82, the temperature of sheet metal 83 returns to room temperature, the thickness of sheet metal 83 is thickening, the outer wall of the inwall and flow channel tube 81 that insert hole 82 clamp sheet metal 83。Sheet metal 83 is deformed into the deviation in the gap absorbed between the inwall and the outer wall of flow channel tube 81 that insert hole 82 to fill up gap, and is adjacent on the outer wall of the inwall with flow channel tube 81 that insert hole 82。

In shrink fit, sheet metal 83 is wrapped on the outer wall of flow channel tube 81, and in the insertion hole 82 of the strengthening part 98 heated, inserts sheet metal 83 and flow channel tube 81。Afterwards, if the temperature of strengthening part 98 returns to room temperature, then the diameter inserting hole 82 reduces, the outer wall of the inwall and flow channel tube 81 that insert hole 82 clamp sheet metal 83。Sheet metal 83 is deformed into the deviation in the gap absorbed between the inwall and the outer wall of flow channel tube 81 that insert hole 82 to fill up gap, and is adjacent on the outer wall of the inwall with flow channel tube 81 that insert hole 82。

So, no matter being shrink-fit or shrink fit, sheet metal 83 is all deformed into the deviation in the gap absorbed between the inwall and the outer wall of flow channel tube 81 that insert hole 82 to fill up gap, and is adjacent on the outer wall of the inwall with flow channel tube 81 that insert hole 82。Thus, thermal contact resistance reduces further, and the homoiothermic efficiency of rear fender 135 becomes better。Further, when absorbing the deviation in above-mentioned gap, owing to soft sheet metal 83 can be suppressed optionally to deform, harder flow channel tube 81 local deformation, therefore can reduce the damage of flow channel tube 81。

It addition, the flow channel tube 81 of the present embodiment is fixed on insertion hole 82 with shrink-fit or shrink fit, but this fixing means is not limited to shrink-fit and shrink fit。Such as have in inserting hole 82, insert flow channel tube 81, make the molten resin heated flow into the gap between the inwall and the outer wall of flow channel tube 81 that insert hole 82 method etc. of cooling curing molten resin。Now, as the resin bed of heat transfer component between the inwall and the outer wall of flow channel tube 81 that insert hole 82。The hardness of resin bed is lower than the hardness of flow channel tube 81。

It addition, in the present embodiment, heat transfer component is between the inwall and the outer wall of flow channel tube 81 that insert hole 82, but can also not have heat transfer component。That is, insert hole 82 inwall and flow channel tube 81 outer wall also by shrink-fit or shrink fit directly against。

It addition, the strengthening part 98 of the present embodiment is formed the insertion hole 82 as the insertion section inserting flow channel tube 81, but also can be identically formed insertion groove with the embodiment 6 of Figure 17 and replace inserting hole。
