The specific embodiment

Below, with reference to the description of drawings embodiments of the present invention.

The 1st embodiment

Fig. 1 is that expression will be as the main portion of the vehicle door interior trim 10 of an example of the inside of automotive part that has used band epidermis foaming and molding member of the present invention, together with the cutaway view of vehicle window 80 and sealing strip for door frame 70 expressions.

With reference to Fig. 1, vehicle door interior trim 10 (being equivalent to be with epidermis foaming and molding member) has core 20, epidermis 30, foaming body 40 and stationary member 50, and above-mentioned core 20 freely bends by kink 23; Above-mentioned epidermis 30 is faced mutually with core 20; Above-mentioned foaming body 40 is filled in the space between core 20 and the epidermis 30; Said fixing member 50 is used for the core 20 that becomes one with epidermis 30 and foaming body 40 and bent by kink 23 is fixed.The core 20 of illustrated example is that the boundary is divided into main part 21 and extension 22 with kink 23, and the extension 22 that has bent by kink 23 is fixed on the main part 21 by stationary member 50.Epidermis 30 forms the surface of inside of automotive part.

Kink 23 is made of hinge, and it is thin than other positions of core 20 that this hinge is formed wall thickness.Can make kink simply.

Under the state of core 20 before bending, main part 21 becomes the roughly angle of 90 degree (with reference to Fig. 2 described later, Fig. 3 and Fig. 4) with extension 22 near hinge 23.On main part 21, be provided with the flange surface 24 of the face shaping that is used for definite vehicle door interior trim 10 tops.

On the extension 22 of core 20, be formed with through hole 25.On the other hand, on the main part 21 of core 20, be formed with the fixing lug boss portion 26 that is inserted in the through hole 25.Extension 22 turned back to the through hole 25 with extension 22 be inserted in the fixing lug boss portion 26 of main part 21.Utilization is integrally formed in a plurality of ribs 27 of fixing lug boss portion 26 peripheries and strengthens fixing lug boss portion 26.

Stationary member 50 can adopt the extension 22 that is used for having bent to be fixed in suitable member on the main part 21.In illustrated example, use bolt as stationary member 50.Bolt 50a is passed the through hole 25 of extension 22 and be anchored in the fixing lug boss portion 26, thereby the extension 22 that will bend is fixed on the main part 21.

On the extension 22 of core 20, be provided with flank 28, between this flank 28 and epidermis 30, be formed with the sealing 60 of seal foaming body 40.Flank 28 is arranged in outstanding towards the back side 30b of epidermis 30 with near the terminal part 31 relative positions of epidermis 30.When filling foaming body 40, the back side 30b closed contact of front end by making flank 28 and epidermis 30 produces to interfere and forms sealing 60, thereby prevents that foaming body 40 from spilling.

Sealing 60 is preferably can freely discharge the gas of following filling foaming body 40 and producing.This is owing to pass through to discharge gas, has eliminated producing the phenomenon that gas is detained between epidermis 30 and the extension 22, thereby can prevent to produce the not filling part of foaming body 40.For gas is freely discharged, the part of cutting flank 28 preestablishes sealing band such as flexibel polyurethane band again and gets final product at this position.Adopt such sealing 60, can discharge gas and can realize sealing, can prevent because gas is detained the not filling that causes.In addition, need not open shaping die a little in order to discharge gas.

On the extension 22 of core 20, be provided with the flange part 29 that is used to install part 70.The extension 22 of core 20 extends longlyer than the terminal part 31 of epidermis 30.It is outstanding that flange part 29 is arranged to towards the zone that does not have epidermis 30 (zone from the terminal part 31 of epidermis 30 to the end of extension 22).The flange part 29 of illustrated example is arranged to relatively approach the terminal part 31 of epidermis 30.

With the part 70 that is installed on the flange part 29 terminal part 31 of epidermis 30 is hidden.

The part 70 of illustrated example is a sealing strip for door frame.Sealing strip for door frame 70 have the installation portion 71 that is installed on the flange part 29, with vehicle door interior trim 10 contacted sealed lips 72 and with the contacted sealed lip 73 of vehicle window 80 inside faces.The terminal part 31 that the front end of sealed lip 72 is crossed epidermis 30 contacts with epidermis 30, thereby the terminal part 31 of epidermis 30 is hidden.

In the epidermis that will be involved in by lining cement was pasted on execution of work in the past on the core, core end, the part that promptly begins to be involved in epidermis were positioned at showy place, therefore, must the seal foaming body to avoid influencing face shaping, quality.Therefore, can not carry out the sealing of foaming body fully, foaming body might spill and be attached to the back side of epidermis, promptly be pasted on the face of core side.Consequently, when being involved in epidermis and being pasted on it on core, in the showy place of epidermal surface concaveconvex shape appears.In addition, under the situation that foaming body spills in a large number, just become the shaping waste product sometimes.

Relative therewith, in the present embodiment, constitute sealing 60 owing to make flank 28 and epidermis 30 closed contacts produce to interfere, therefore, and abundant seal foaming body 40, thus can prevent that foaming body 40 from spilling from the terminal part 31 of epidermis 30.And because the terminal part 31 of epidermis 30 extends to the extension 22 of core 20, therefore, just terminal part 31 and the sealing 60 with epidermis 30 has been set in background.In other words, background is the position in addition, position that must pay attention to the products appearance quality.Therefore, even the situation that foaming body 40 spills from the terminal part 31 of epidermis 30 takes place, spilling of foaming body 40 is unshowy yet, therefore, can not reduce the presentation quality of goods.In addition, if improve sealing property and strengthen contacting of flank 28 and epidermis 30, can so and at the surperficial 30a of epidermis 30 concaveconvex shape appear then.Even under these circumstances,, therefore also can not reduce the exterior quality of goods because the concaveconvex shape that presents is unshowy.In addition, make the sealed lip 72 of sealing strip for door frame 70 overlapping, terminal part 31 is hidden, therefore, can hide the concaveconvex shape of the spilling of foaming body 40, epidermis 30, can not reduce the presentation quality of goods by sealing strip for door frame 70 with the terminal part 31 of epidermis 30.

Epidermis 30, core 20, and foaming body 40 can suitably select known material respectively.For example, the material of epidermis 30 can adopt Vinyl chloride resin (PVC), polyolefin thermoplastic elastomer (TPO), polyurethane series thermoplastic elastomer (TPU) etc.Epidermis 30 is configured as the shape of utilizing vacuum forming etc. and determining.The material of core 20 can adopt acrylic resin (PP), acrylonitrile butadiene styrene resin (ABS) etc.Foaming body 40 for example can use isocyanurate foam.

The manufacture method of vehicle door interior trim 10 then, is described.

Fig. 2 is the cutaway view that is illustrated in the state that has disposed epidermis 30, core 20 in the shaping die of opening 100, and Fig. 3 is the cutaway view that the operation of shaping die 100, filling foaming body 40 is closed in expression.Fig. 4 is the cutaway view of the expression state that will take out from shaping die 100 with the core 20 that epidermis 30 and foaming body 40 become one, Fig. 5 be expression by the cutaway view of kink 23 with the state of extension 22 bending of core 20, the extension 22 of Fig. 6 core 20 that to be expression will bend with stationary member 50 is fixed in the cutaway view of the state on the main part 21.

With reference to Fig. 2, shaping die 100 have can be relatively near or the chamber mould 101, the core 102 that move freely with deviating from.In illustrated example, chamber mould 101 with respect to core 102 carry out approaching, deviate from mobile.On chamber mould 101, be formed with the die cavity of the interior shape shape that the outer shape with epidermis 30 matches.Configuration core 20 under the extended configuration in core 102 before main part 21 and extension 22 bend relatively.Extension 22 is placed on the extension 103 of core 102.Main part 21 is the state of opening about 90 degree with extension 22.

At first, as shown in Figure 2, open chamber mould 101, the core 102 of shaping die 100, the core 20 of configuration extended configuration in core 102, then, configuration epidermis 30 (arrangement step) in chamber mould 101.Epidermis 30 is practised physiognomy with core 20 and is disposed over the ground.

Then, as shown in Figure 3, close shaping die 100, make the front end of flank 28 and the back side 30b closed contact of epidermis 30 produce interference, thereby form sealing 60.Epidermis 30 is faced mutually with the main part 21 and extension 22 both sides of core 20.Then, the foaming body 40 of specified amount is filled in the space between core 20 and the epidermis 30 (filling work procedure).Above-mentioned space comprises spatial portion between epidermis 30 and the main part 21 and the spatial portion between epidermis 30 and the extension 22.Because both sides' spatial portion is in connected state, therefore, has also filled foaming body 40 fully between epidermis 30 and extension 22, thereby form foaming layer at both sides' spatial portion.

Then, as shown in Figure 4, open shaping die 100, will from shaping die 100, take out with the core 20 that epidermis 30 and foaming body 40 become one.The extension 32 and the foaming layer extension 41 of the epidermis of facing mutually by the extension 22 of core 20, with the extension 22 of core 20 30 have formed shaped object extension 11.Because shaped object extension 11 is band integrally with surface skin foam molding, therefore, can solves the epidermis that when the epidermis that will be involved in by lining cement is pasted on the core, produces and peel off or float such problem.

Then, shown in the arrow among Fig. 4, bend towards main part 21 by the extension 22 of hinge 23 with core 20.The extension 22 of this moment becomes one with epidermis 30 and foaming body 40, has formed shaped object extension 11.As shown in Figure 5, shaped object extension 11 is turned back to the fixing lug boss portion 26 of main part 21 being inserted in the through hole 25 of extension 22.About the location of the shaped object extension 11 that turned back, on the directions X shown in Figure 5 (Width), make through hole 25 around the bearing surface of face and fixing lug boss portion 26 rib 27 on every side offset to fetch and position.In addition, Y direction (short transverse) and with the paper of Fig. 5 mutually on the length direction of quadrature, fasten by setting benchmark, secondary standard in the through hole 25 and the pass of fixing lug boss portion 26 and to position.

With reference to Fig. 9, triangle becomes to have slit 207 around claw component 204.Chimeric teat 202 is with cantilevered fashion bearing claw member 204, and allows claw component 204 elastic deflections.The outstanding stop part 208 that is hung on window portion 205 inwalls that is provided with on claw component 204.At the front end of stop part 208, the guide surface 209 that will be used to guide chimeric recess 203 to insert forms cone-shaped.Side opposite with being extruded with stop part 208 sides in chimeric teat 202 two sides is provided with the rib 210 that is used to form for the space of claw component 204 deflections.

With reference to Figure 10, by hinge 23 with extension 22 towards main part 21 bending, on one side with the claw component 204 of the chimeric teat 202 of guide surface 209 guiding of stop part 208, be inserted on one side (Figure 10 (A), (B)) in the chimeric recess 203.If further bending extension 22, claw component 204 downside elastic deflection in the figure on one side then is Yi Bian further enter into chimeric recess 203 (Figure 10 (C)).When stop part 208 arrived window portion 205, claw component 204 flexibly was returned to initial condition (state of Figure 10 (A)), and stop part 208 is hung on the inwall of window portion 205.Thus, claw component 204 fastens with chimeric recess 203, and extension 22 is fixed on the main part 21.On the other hand, remove extension 22 and main part 21 fixedly the time, press the stop part 208 of claw component 204, make stop part 208 leave window portion 205.Thus, can remove the engaging of 204 pairs of chimeric recesses 203 of claw component, with extension 22 and main part 21 relative separation open.

In the Fabrication procedure of vehicle door interior trim 200, except the Fabrication procedure of the 1st embodiment, after fixing operation, also have the cut-out operation of cut-out than the forward distolateral part of stationary member 50.

With reference to Figure 11, be opened at main part 21 and extension 22 under the states of about 90 degree, with core 20 mountings on the mounting surface 104 on the extension 103 of core 102 (arrangement step).Being provided with recess 211 on core 102 interferes with chimeric teat 202 avoiding.In addition, as mentioned above, in the window portion 205 of chimeric recess 203, be pasted with sealing band 206, prevent that the foaming body 40 of filling from entering into window portion 205 (filling work procedure).

With reference to Figure 12 (A), open shaping die 100, will from shaping die 100, take out with the core 20 that epidermis 30 and foaming body 40 become one.With reference to Figure 12 (B), extension 22 is bent towards main part 21 by hinge 23.The claw component 204 of chimeric teat 202 is sticked in chimeric recess 203, thereby extension 22 is fixed in (fixedly operation) on the main part 21.Figure 12 shows the cross section at the position that fixing lug boss portion 26 is not set.As shown in Figure 7, on the cross section that is provided with fixing lug boss portion 26, bolt 50a is anchored in the fixing lug boss portion 26, thereby extension 22 is fixed in (fixedly operation) on the main part 21.

Then, with reference to Figure 12 (C), will be present in than double-type chimeric member 201 forward distolateral shaped object extensions 11 and cut off and remove (cut-out operation).Prevent interference with other parts by removing position not.Owing to cut off than stationary member 50 forward distolateral parts, therefore, stationary member 50 continues extension 22 to remain on the main part 21.Therefore, can on remaining shaped object extension 11, not produce float etc. fixing bad.In illustrated example, not only a severing and a part of having removed the extension 22 of core 20, also a severing and a part of having removed epidermis 30.On the cut off machine of removing 212, comprise flank 28, but, also do not have obstruction even therefore remove because filling work procedure finishes.

In illustrated example, at two kinds of stationary members 50, be in bolt 50a and the double-type chimeric member 201, can cut off than double-type chimeric member 201 forward distolateral parts, but also can cut off forward distolateral part than bolt 50a.In addition, also can all stay epidermis 30, only cut off a part of removing extension 22.In addition, even under the situation of only using a kind of stationary member 50, also can append the cut-out operation.

The aspects such as moulding outward appearance of the restriction during from the indoor configuration of car on the layout, vehicle door interior trim 200 self consider, vehicle door interior trim 200 as the final desired bending length L a of goods (with reference to Figure 12 (C)) with in the drawings with paper mutually quadrature direction, be the different or local weak point of length on the vehicle fore-and-aft direction.For example, a is long in vehicle front side for the bending length L, and is shorter in the rear view of vehicle side.At this, when the length of the extension 22 of determining core 20 in conjunction with the final bending length L a that requires, the area of extension 22 diminishes, and weight lightens.On the other hand, the hinge 23 that has bent has the elastic force of the extended configuration before the bending of resetting into.Therefore, extension 22 is not mounting surface 104 closed contacts with core 102, but separates with mounting surface 104 and float towards epidermis 30 sides.If under this state, close shaping die 100, then might make extension 22 and epidermis 30 interfere and make epidermis 30 to be offset, thereby produce wrinkle on the semifinished piece.And, also might cause that foaming body 40 spills or produce the inadequate position of filling of foaming body 40 owing to destroying epidermis 30.

As the 2nd embodiment, append the advantage of cutting off operation and be, even under the short situation of the final bending length L a that requires, also can guarantee the fixed-area of extension 22 fully with respect to core 102.Thus, both can satisfy the restriction on the layout, the requirement of moulding outward appearance, can prevent from again to produce that epidermis 30 skew, foaming body 40 spill, foaming body 40 fills insufficient etc.In addition, though produce cut off machine 212, its generation and whole goods are that the situation of waste product compares is hoot.Therefore, even append the cut-out operation, also can not reduce the effective rate of utilization of material.

With reference to Fig. 8 and Figure 11, core 20 is placed on the core 102 in the state download that main part 21 and extension 22 are opened for about 90 degree.Under this state, owing in Fig. 8, iris out the inversion shape 220 of expression and the core 20 that can not be shaped by long and two-short dash line.With reference to Figure 13, in order to use the die insert 221,222 that can be free to slide to come core 20 is carried out injection molding forming, in the mould 223 of shaping core 20, be provided with die cavity 224, to form the core 20 of opening about 180 degree shapes with respect to final bending shape (with reference to Fig. 7).

Make core 20 behind the injection molding forming maintain shape when being shaped, when the temperature of core 20 dropped to normal temperature, the shape of core 20 was frozen for being the degree of the shapes of having opened about 180 degree in the middle of main part 21 and the extension 22.Therefore, the semifinished piece temperature drops to after the normal temperature, if bending hinge 23, then hinge 23 ruptures easily.In addition, as shown in figure 16, even under the bigger situation of the area of extension 22, when the elastic force of hinge 23 is big, extension 22 also can float towards epidermis 30 sides from the mounting surface 104 of core 102, and is hour identical with the area of extension 22, when closing shaping die 100, might make epidermis 30 skews, thereby produce wrinkle etc. on the semifinished piece.

Therefore, preferably before being configured operation, also have the preparation shape and give operation, this preparation shape is given operation and is given folding line by in fixing operation core 20 being bent towards overbending direction, thereby core 20 is given the preparation shape of the mounting surface 104 of the configuration core 20 in the imitation shaping die 100.Even this is because also frangibility hinge 23 not of bending hinge 23.In addition, as shown in figure 15,, make epidermis 30 produce skew in the time of therefore can preventing to close shaping die 100, thereby can obtain non-wrinkle goods because core 20 can not float towards epidermis 30 sides.

The preparation shape give operation preferably after shaping core 20, the drop in temperature of core 20 carried out before normal temperature.This be because, the shape freezing of the core 20 after being shaped carries out before being the shape of opening, and gives the preparation shape to core 20 easily.

Give in the operation in the preparation shape, preferably give folding line with the core 20 of stationary member 50 fixing bendings.This is because do not need to use the parts peculiars such as anchor clamps that core 20 maintained bending state like this.As shown in figure 14, utilize double-type chimeric member 201 that hinge 23 is bent about 180 degree and keeps this state, give folding line core 20 as stationary member 50.Because chimeric teat 202 can freely engage and engagement release with respect to chimeric recess 203 by claw component 204, therefore, can be simply the core 20 that has been shaped be maintained bending state and take care of.In addition, when mounting is on shaping die 100, can remove the engaging of claw component 204 simply, can not increase core 20 is arranged at time on the core 102.Certainly, owing to do not need to be bent into the such correction operation of shape of imitation mounting surface 104, therefore, can reduce that core 20 is arranged at time on the core 102 with the shape that manual manipulation will be left the core 20 of mounting surface 104.

In addition, do not have freely at stationary member 50 under the situation of structure of engaging and engagement release, can give the preparation shape to core 20 by using parts peculiars such as anchor clamps.

Figure 17 be the expression band epidermis foaming and molding member that used the 3rd embodiment vehicle door interior trim 230 want portion's cutaway view, be the cutaway view of representing further to make the extension of reflex part 231 and the core 20 that has bent 22 overlapping, also being fixed in the state on the main part 21 with stationary member 50.Figure 18 is illustrated in the cutaway view that disposes the state of epidermis 30 and core 20 in the shaping die of opening 100.Figure 19 is that shaping die 100, the cutaway view of the operation of filling foaming body 40 are closed in expression.Figure 20 is the cutaway view of the expression state that will take out from shaping die 100 with the core 20 that epidermis 30 and foaming body 40 become one.Figure 21 is expression be used to the to be shaped cutaway view of mould 234 of core 20.In addition, to the member mark identical Reference numeral identical, thereby omit the part of its explanation with the member shown in Fig. 1～Figure 16.

The 3rd embodiment is the core 20 that the part more than 3 is relatively freely bent, and is different with the 1st embodiment of two cores of rolling over 20 in this.

With reference to Figure 17, say that summarily the core 20 of the 3rd embodiment also comprises the 2nd kink 232 of the end of being located at extension 22 and turns back and the reflex part 231 overlapping with extension 22 by the 2nd kink 232.

The 2nd kink 232 is made of the hinge 232 that forms than other position wall thickness in the core 20.Hinge 232 forms reflex part 231 is turned back towards the back side of extension 22.

Being formed with on reflex part 231 that the 2nd through hole 233, the 2 through holes 233 are formed on hinge 232 is the position of through hole 25 symmetries of center and extension 22.Make the back side of itself and extension 22 overlapping if reflex part 231 turned back, then through hole 25 and the 2nd through hole 233 are connected state.The bolt 50a that is used as stationary member 50 reaches extension 22 and is fixed on the main part 21 with extension 22 overlapping reflex parts 231.

Make vehicle door interior trim 230 in the same manner with the 1st embodiment.

With reference to Figure 18, open under about 90 states of spending core 20 mountings (arrangement step) on core 102 at main part 21 and extension 22.With reference to Figure 19, close shaping die 100, the foaming body 40 of specified amount is filled in the space between core 20 and the epidermis 30 (filling work procedure).With reference to Figure 20, open shaping die 100, will from shaping die 100, take out with the core 20 that epidermis 30 and foaming body 40 become one.By hinge 232 reflex part 231 is turned back towards extension 22 back sides, make the back side of itself and extension 22 overlapping.And, as shown in figure 17, be anchored in the boss portion 26 being inserted into the through hole 25 that is connected state and the bolt 50a in the 2nd through hole 233, thereby extension 22 and reflex part 231 be fixed in (fixedly operation) on the main part 21 together.

By at the further additional reflex part 231 of the front end of extension 22, identical with the 2nd embodiment, even under the short situation of the final bending length L a that requires, also can guarantee the fixed-area of extension 22 fully with respect to core 102.Thus, both can satisfy restriction, moulding outward appearance on the layout, can prevent again that epidermis 30 skew, foaming body 40 spill, foaming body 40 fills insufficient etc.In addition, by making extension 22 and the reflex part 231 overlapping rigidity that improved, strengthened the fastening fixing of bolt 50a.

With reference to Figure 21, in mould 234, core 20 is configured as main part 21, extension 22, and reflex part 231 open the shapes of about 180 degree.Therefore, identical with the 2nd embodiment, preferably also have the preparation shape of preparation shape of giving the mounting surface 104 of imitation shaping die 100 and give operation core 20.

The 4th embodiment

Figure 22 is expression be used to the to be shaped cutaway view of mould 240 of core 20 of the 4th embodiment, and Figure 23 is the cutaway view of the state that deforms of the core 20 of expression mounting on shaping die 100.Figure 22 represents not to be provided with the cross section at the position of through hole 25.In addition, to the member mark identical Reference numeral identical, thereby omit the part of its explanation with the member shown in Fig. 1～Figure 21.

With reference to Figure 22, become the shape that just can be shaped in order to make core 20 without sliding die, and for example in mould 240 be with core 20 injection molding formings make main part 21, and extension 22 for opening the shapes of about 180 degree.

With reference to Figure 23, shaping die 100 comprise the core 102 (being equivalent to the core mould) that is used to dispose core 20 and be used to dispose epidermis 30 and can with respect to core 102 relatively free near or deviate from mobile chamber mould 101 (being equivalent to the epidermis mould).In illustrated example, chamber mould 101 carries out approaching with respect to core 102 or deviates from mobile.Open at main part 21 and extension 22 under the states of about 90 degree core 20 mountings on the mounting surface 104 of core 102 (arrangement step).Shape when the core 20 after the injection molding forming is maintained shaping, when the temperature of core 20 dropped to normal temperature, the shape freezing of core 20 was the degree that is the shapes of having opened about 180 degree between main part 21 and the extension 22.Therefore, extension 22 is not with mounting surface 104 closed contacts of core 102 but separates with mounting surface 104 and float towards epidermis 30 sides.Under this state,, then might make extension 22 and epidermis 30 interfere and make epidermis 30 to be offset, thereby produce wrinkle on the semifinished piece if close shaping die 100.In addition, also might cause that foaming body 40 spills, produces foaming body 40 and fills inadequate position owing to destroying epidermis 30.

Therefore, preferably make core 102 and chamber mould 101 carry out extension 22 being remained on the mounting surface 104 in order to close shaping die 100 relative near before moving.Because can prevent at location extension 22 like this, take place when closing shaping die 100 that epidermis 30 skews, foaming body 40 spill, foaming body 40 fills insufficient etc.So-called " core 102 carried out before approaching moving with chamber mould 101 " is meant, with after core 20 mountings are on core 102, and then

core

102 and 101 beginnings of chamber mould are about to make the moment of epidermis 30 between being offset near moving, interfering up to extension 22 and epidermis 30.

At this, have as the structure that extension 22 is remained on the mounting surface 104: from extension 22 being remained in the moment on the mounting surface 104, carry out relatively near the structure of the action interlock that moves and the structure of interlock not with make core 102 and chamber mould 101 in order to close shaping die 100.

In the former structure of interlock, comprise and carry out the structure (the 5th embodiment) that makes the action that extension 22 moves towards the mounting surface 104 of core 102 relative to converting to according to the structure (the 4th embodiment) of the shape interlock of the shape of core 20 and chamber mould 101 and with core 102 and chamber mould 101 near the action of moving.

In the structure of the latter's not interlock, can adopt suitable mechanism, for example can adopt extension 22 is pushed on dipper crowding gear 280 (the 6th embodiment) on the mounting surface 104, draws attraction mechanism 300 (the 7th embodiment) of extension 22 etc. from the trailer coupling 290 (the 7th embodiment) of mounting surface 104 1 side-lining extensions 22, from mounting surface 104 1 side draughts.Below, illustrate successively extension 22 is remained in various structures on the mounting surface 104.

Can before filling foaming body 40 finishes, extension 22 be remained on the mounting surface 104.Discharge follow filling foaming body 40 and during the gas that produces temporary transient the releasing extension 22 is remained on the mounting surface 104.Owing to when discharging gas, open shaping die 100 a little, therefore, under the state that extension 22 is remained on the mounting surface 104, might produce wrinkle on the semifinished piece.In addition, as the 1st embodiment, under situation, need not open shaping die 100 in order to discharge gas with sealing 60 that the gas that can will follow filling foaming body 40 and produce freely discharges.

When foaming body 40 solidifies, can extension 22 not remained on the mounting surface 104 yet.This is because act on the Clamping force that shaping die 100 is arranged on extension 22, because the filling of foaming body 40 also finishes, therefore, can fully overcome the power that extension 22 floats towards epidermis 30 1 sides.

Self-evident, in the time will from core 102, taking out, remove that extension 22 is remained on the mounting surface 104 with the core 20 that epidermis 30 and foaming body 40 become one, make core 20 and core 102 be in loose state.

In the 4th embodiment, carry out relative to linkedly extension 22 pushings being remained on the mounting surface 104 near the action of moving with make core 102 and chamber mould 101 in order to close shaping die 100.

Core 20 has and is configured to from the outstanding protrusion 250 of extension 22.Chamber mould 101 has guide surface 252, and this guide surface 252 carries out relative near the action of moving linkedly with making chamber mould 101 and core 102, contacts with the outstanding front end 251 of protrusion 250 and extension 22 is moved towards the mounting surface 104 of core 102.

The protrusion of being located on the extension 22 250 is preferably used the flange part 29 (with reference to Fig. 1) that is used to install sealing strip for door frame 70 (being equivalent to part).This is to get final product because need not to be provided with the special-purpose protrusion that aims at pushing extension 22 and use.

In filling work procedure, when the action of closing shaping die 100 began, the guide surface 252 of chamber mould 101 contacted with the outstanding front end 251 of protrusion 250.When chamber mould 101 was moved further, extension 22 was directed face 252 pushing by protrusion 250, be that center anticlockwise direction in figure rotates with hinge 23, moved towards the mounting surface 104 of core 102.Then, when chamber mould 101 moved to the matched moulds position, extension 22 was pushed on the mounting surface 104 and mounting surface 104 closed contacts, thereby is held on the mounting surface 104.Like this, extension 22 is pushed on the mounting surface 104 and with the state of mounting surface 104 closed contacts under, just can carry out foaming and molding.

This modified example forms thin-walled with the outstanding front end 254 of protrusion 253, and makes outstanding front end 254 have flexible.

When the guide surface 252 of chamber mould 101 contacts with the outstanding front end 254 of protrusion 253, have flexible outstanding front end 254 deflections.By the antagonistic force that utilizes produce this moment, can remain on extension 22 on the mounting surface 104 and it is more closely contacted with this mounting surface 104.In addition, even after closing shaping die 100, protrusion 253 also can produce antagonistic force.Therefore, can keep the state of extension 22 and mounting surface 104 closed contacts.In addition,, the antagonistic force of generation can be adjusted, optimal creating conditions can be set simply by adjusting the thickness of slab of outstanding front end 254.

Figure 26 (A), (B) be used to illustrate the 4th embodiment another modified example want portion's cutaway view, Figure 27 is the block diagram that near the protrusion 255 the front end of extension 22 is located in expression.

In this modified example, the root of protrusion 255 is bearing on the extension 22 with cantilevered fashion, makes whole protrusion 255 have flexible.On the guide surface 252 of chamber mould 101, the position that becomes the moving direction front during with matched moulds forms the conical surface 257.Utilize the conical surface 257 guiding boss 255 more successfully.On core 102, be formed with the slot to avoid 258 of allowing protrusion 255 deflections.

When the guide surface 252 of chamber mould 101 contacts with the outstanding front end 256 of protrusion 255, have the 255 whole deflections of flexible protrusion.By the antagonistic force that utilizes produce this moment, can remain in extension 22 on the mounting surface 104 and it is more closely contacted with this mounting surface 104.In addition, even close after the shaping die 100, protrusion 255 also can produce antagonistic force.Therefore, can keep the state of extension 22 and mounting surface 104 closed contacts.In addition,, the antagonistic force of generation can be adjusted, optimal creating conditions can be set simply by adjusting the thickness of slab of protrusion 254 roots.

In this modified example, protrusion 259 has the door shape of the front end of being located at extension 22 free to rotately.Protrusion 259 has from extension 22 towards figure outstanding the 1st plate 261 in top and from extension 22 towards figure outstanding the 2nd plate 262, the 1 plates 261 and the 2nd plate 262 in below become one.By the connecting portion 260 between protrusion 259 and the extension 22 is formed thin-walled, be that rotate at the center with connecting portion 260 and make protrusion 259.On the guide surface 252 of chamber mould 101, be formed with the 1st stage portion 263 that tangles the 1st plate 261, on core 102, be formed with the 2nd stage portion 264 that tangles the 2nd plate 262.

When chamber mould 101 moves, when the 1st stage portion 263 of guide surface 252 contacted with the outstanding front end 265 of the 1st plate 261, protrusion 259 was center anticlockwise motion in figure with connecting portion 260.When chamber mould 101 moved to the matched moulds position, the 1st stage portion 263 pushings the 1st plate 261 of guide surface 252 was that the 2nd plate 262 that fulcrum rotates hangs on the 2nd stage portion 264 of core 102 with connecting portion 260, pushes the 2nd stage portion 264.The 2nd plate 262 is pushed on power on the 2nd stage portion 264, becomes and extension 22 is pulled into the power of core 102 and acts on the extension 22.Extension 22 be pushed on the mounting surface 104 and with mounting surface 104 closed contacts, be held in thus on the mounting surface 104.Like this, by utilizing lever, can remain in extension 22 on the mounting surface 104 and it is more closely contacted with this mounting surface 104.In addition, even close after the shaping die 100, also can produce the power that extension 22 is pulled into core 102.Therefore, can keep the state of extension 22 and mounting surface 104 closed contacts.In addition, the thickness of slab of each plate 261,262 by adjusting protrusion 259 can be adjusted the power of generation, can set optimal creating conditions simply.

The 5th embodiment

Identical with the 4th embodiment, the 5th embodiment also be with make in order to close shaping die 100 core 102 and chamber mould 101 carry out relative near the action of moving linkedly, extension 22 be pushed on the mounting surface 104 keep.

In the 5th embodiment, utilization will make core 102 and chamber mould 101 carry out the switching mechanism 270 that makes the action that extension 22 moves towards the mounting surface 104 of core 102 relative to being converted near the action of moving, and extension 22 will be pushed on the mounting surface 104 keep.

Switching mechanism 270 has the tilt slide structure, comprises the angled pin of being located on the chamber mould 101 271 and can be free to slide the sliding die of being located at movably on the core 102 272.At the elastic mechanisms such as spring 275 that are provided with the bullport 273 that is used to insert angled pin 271 on the sliding die 272, extension 22 is pushed on the pin member 274 on the mounting surface 104 and pin member 274 is applied elastic force.Elastic mechanism constitutes freely to adjust extension 22 is pushed on load on the mounting surface 104.

In filling work procedure, the action of closing shaping die 100 at the beginning, the angled pin 271 of chamber mould 101 just enters into the bullport 273 of sliding die 272.When chamber mould 101 is moved further, under the combined action of angled pin 271 and bullport 273, sliding die 272 towards extension 22 mechanically interlock move.And when chamber mould 101 moved to the matched moulds position, extension 22 had been applied in the effect of the pin member 274 of elastic force, and be pushed on the mounting surface 104 and with these mounting surface 104 closed contacts, thereby be held on the mounting surface 104.Like this, under being pushed on extension 22 on the mounting surface 104 and remaining state with mounting surface 104 closed contacts, just can carry out foaming and molding.

In this modified example,, be provided with the elastic mechanisms such as spring 277 that extension 22 is pushed on the pin member 276 on the mounting surface 104 and pin member 276 is applied elastic force on the chamber mould 101 as switching mechanism 270.Elastic mechanism constitutes freely to adjust extension 22 is pushed on load on the mounting surface 104.Because the bight of pin member 276 forms rounded shapes, therefore, pin member 276 can easily be crossed over flank 28.

If core 102 carries out then selling member 276 and contacting with extension 22 relative near moving with chamber mould 101, pin member 276 makes extension 22 move towards the mounting surface 104 of core 102 by the elastic force that elastic component applies.And when chamber mould 101 moved to the matched moulds position, extension 22 had been applied in the effect of the pin member 276 of elastic force, and be pushed on the mounting surface 104 and with these mounting surface 104 closed contacts, thereby be held on the mounting surface 104.
