Specific embodiment

Thinking of the invention is: in order to solve the problems, such as intermediate deformation of the mold mounting plate when bearing mold clamping force under hot pressing, Mold mounting plate under hot pressing is rationally set between 2 horizontal rails on lower bearing bracket corresponding to left hot pressing station and right hot pressing station Supporting point, that is, supporting part (may be designed to height adjustable structure；Such as tied using screw rod adjustment structure or waist round hole and bolt cooperation Structure), when left hot pressing upper mold and the molding of left hot pressing lower die or right hot pressing upper mold and the molding of right hot pressing lower die, mold mounting plate under hot pressing Decline is directly contacted with supporting part, carries mold mounting plate under hot pressing by supporting part；In hot pressing molding, supporting part becomes hot pressing The supporting point of lower mold mounting plate, to prevent mold mounting plate stress deformation under hot pressing and hot pressing upper mold and hot pressing lower die is made to keep flat Row also avoids the situation that whole mold clamping forces are born by sliding block and horizontal rail, to extend the use of sliding block and horizontal rail Service life.

But if mold mounting plate and supporting part are also kept in contact when moving horizontally under hot pressing, the installation of hot pressing lower die Friction can be generated between plate and supporting part, this friction problem does not solve, and left hot pressing lower die and right hot pressing lower die move horizontally With regard to unstable, and after long-time is worn, supporting part height will be reduced, and the supporting point of mold mounting plate will lose under hot pressing Effect.

Therefore, it should accomplish that mold mounting plate is directly contacted with supporting part under hot pressing when hot pressing molding, realizes work as hot pressing again Lower mold mounting plate does not have frictional force between supporting part in translation.We have invented under heat between mold mounting plate and sliding block Elastomeric element is filled, bullet when in hot pressing molding state, under the action of mold clamping force, under hot pressing between mold mounting plate and sliding block Property component is compressed, and mold mounting plate moves down under the hot pressing of fixed hot pressing lower die, touches the supporting part on lower bearing bracket, supporting part Bear the largely or entirely mold clamping force that mold mounting plate passes under hot pressing；When hot pressing die sinking, in elastomeric element screen resilience Under the action of, mold mounting plate has suitable rising relative to its position of supporting part under hot pressing, and mold mounting plate is relative to holding under hot pressing Heavy mail floats, and completely disengages the supporting part being fixed on lower bearing bracket, mold mounting plate is in horizontal movement Shi Buyu supporting part under hot pressing Contact, avoids friction of the mold mounting plate in horizontal movement between supporting part under hot pressing, completely eliminates hot pressing lower die peace Frictional force of the loading board in horizontal movement between supporting part, the resistance that hot pressing lower die moves horizontally can greatly reduce.In this way, by Servo motor drives left hot pressing lower die and right moving horizontally for hot pressing lower die to become possibility, has saved mold mounting plate under hot pressing and has existed Energy consumption when horizontal movement, and improve the precision of the stability and positioning that move horizontally.

As shown in Fig. 3, Fig. 4, Fig. 5, Fig. 5 .1, Fig. 5 .2, Fig. 5 .3, sliding block 9 can left and right in mould horizontal rail 8 under heat Level sliding fills between mold mounting plate under hot pressing (including under left hot pressing under mold mounting plate and right hot pressing mold mounting plate) and sliding block 9 Flexible component 11a (preferably spring or other elastomers), specific method is as shown in Fig. 5, Fig. 5 .1, Fig. 5 .2, Fig. 5 .3, spring Upper holder block 11b is fixed together with mold mounting plate under hot pressing, and spring downward block 11c is fixed together with sliding block 9；Such as Fig. 5 .1, figure 5.2, shown in Fig. 5 .3, one group of elastomeric element, spring upper holder block 11b are housed between spring upper holder block 11b and spring downward block 11c Spring lock block guide pin 11d is also equipped between spring downward block 11c, spring lock block guide pin 11d is fixed on spring downward block 11c On, spring upper holder block 11b covers on spring lock block guide pin 11d, can slide up and down in vertical direction along spring lock block guide pin 11d； When spring upper holder block 11b elastomeric element elastic force effect under along spring lock block guide pin 11d upward sliding, but on move on to certain position It postpones and is held by spring lock block guide pin 11d；So spring upper holder block 11b can be done with spring downward block 11c in vertical direction It is quantitative to relatively move but perform relative motion in the horizontal direction.When left thermocompression forming device 3 and right thermocompression forming device 4 are in When die opening state, spring upper holder block 11b moves up a certain distance under the action of elastomeric element elastic force, then mold mounting plate under hot pressing Position relative to sliding block and horizontal rail 8 also moves up a certain distance, and mold mounting plate floats referred to as under hot pressing.When left hot pressing When shaping equipment 3 and right thermocompression forming device 4 are in molding state, under the action of mold clamping force, mold mounting plate and cunning under hot pressing One group of elastomeric element between block is compressed, and the spring upper holder block 11b of mold mounting plate is along spring lock block guide pin under fixed hot pressing 11d slide downward, mold mounting plate also declines a certain distance relative to the position of sliding block and horizontal rail 8 under hot pressing, referred to as Mold mounting plate moves down under hot pressing.It is also possible to spring lock block guide pin 11d to be fixed on spring upper holder block 11b, spring downward block 11c covers on spring lock block guide pin 11d, and working principle is same as described above.Spring upper holder block 11b can be along being fixed on spring Spring lock block guide pin 11d on lower lock block 11c is slided up and down relative to spring downward block 11c or spring upper holder block 11b is solid Determine spring lock block guide pin 11d to slide up and down relative to spring downward block 11c, spring lock block guide pin 11d ensures spring Upper holder block 11b cannot be relatively moved in the horizontal direction with spring downward block 11c, also ensure that under hot pressing mold mounting plate relative to Sliding block cannot relatively move in the horizontal direction, to ensure that the accuracy that mold mounting plate positions in the horizontal direction under hot pressing.

As shown in Fig. 5 .1, Fig. 5 .2, it is respectively arranged on the left hot pressing station 3.1 and right hot pressing station 4.1 of lower bearing bracket Supporting part 10 (supporting part and lower bearing bracket can be integrally formed), the supporting part are at least one bearing block or one group of idler wheel；When left heat Pressure upper mold and left hot pressing lower die mold at left hot pressing station 3.1, under the action of mold clamping force, mold mounting plate and cunning under left hot pressing Elastomeric element between block is compressed, and mold mounting plate moves down under left hot pressing, until mold mounting plate touches institute simultaneously under left hot pressing Its corresponding supporting part 10, supporting part carry mold mounting plate under left hot pressing, and corresponding spring upper holder block 11b and spring downward Gap is also maintained between block 11c, mold clamping force is transmitted to supporting part 10；Equally, when right hot pressing upper mold and right hot pressing lower die are on the right side When hot pressing station 4.1 molds, under the action of mold clamping force, the elastomeric element under right hot pressing between mold mounting plate and sliding block is pressed Contracting, mold mounting plate moves down under right hot pressing, until mold mounting plate touches its corresponding supporting part 10, load-bearing simultaneously under right hot pressing Part carries mold mounting plate under right hot pressing, and between also being maintained between corresponding spring upper holder block 11b and spring downward block 11c Gap, mold clamping force are transmitted to supporting part 10.For supporting part 10 under heat on the lower bearing bracket under mold mounting plate, it is reasonable to carry out as needed Distribution, it is entirely avoided mold mounting plate stress deformation phenomenon under hot pressing ensure that the level of mold mounting plate under hot pressing, and sufficiently protect The depth of parallelism for having demonstrate,proved upper/lower die avoids the situation that whole mold clamping forces are born by sliding block, thus extend the service life of sliding block, Equipment is set to run more stable, positioning accuracy is higher.

When left thermocompression forming device 3 and right thermocompression forming device 4 are in die opening state, under left hot pressing mold mounting plate 3e and Mold mounting plate 4e floats under right hot pressing, and mold mounting plate is detached from supporting part 10 under hot pressing, and keeps in vertical direction and supporting part 10 Certain interval, this gap are usually smaller or very little, but avoid under hot pressing mold mounting plate in horizontal movement When contact with supporting part, completely eliminate frictional force of the mold mounting plate in horizontal movement between supporting part under hot pressing, heat Pressure mould can be greatly reduced along the resistance of horizontal orbital movement, save energy consumption of the mold mounting plate in horizontal movement under hot pressing, Increase the stationarity of movement and the accuracy of positioning.

Alternatively, hot pressing die is in die sinking and molding, fixed hot pressing lower die when the supporting part 10 is one group of idler wheel Hot pressing under mold mounting plate can also without floating and moving down, under hot pressing between mold mounting plate and sliding block 9 can equipped with elasticity Component can also not have elastomeric element；It is this when mold mounting plate does not float and moves down under the hot pressing of fixed hot pressing lower die What sample was implemented: under hot pressing molding state, same group of idler wheel touches mold mounting plate under corresponding hot pressing, idler wheel branch simultaneously Hold mold mounting plate under left hot pressing；Under hot pressing die opening state, mold mounting plate is under hot pressing under the hot pressing of fixed hot pressing lower die Mould horizontal rail 8 idler wheel upper direction then, mold mounting plate directly rolls on idler wheel under hot pressing, is not required to move up disengaging rolling Wheel, until mold mounting plate is moved horizontally along hot pressing lower die horizontal rail 8 and left idler wheel above completely under hot pressing, because of hot pressing lower die peace Force of rolling friction very little of the loading board when rolling on idler wheel, hot pressing lower die can also be greatly reduced along the resistance of horizontal orbital movement, Energy consumption of the mold mounting plate in horizontal movement under hot pressing has been saved, the stationarity of movement and the accuracy of positioning are increased.

There is no original same category of device of supporting part 10, is separated by relatively large distance because sliding block 9 can only be distributed across two or two groups Hot pressing lower die horizontal rail 8 on, and wet base transfer mould 7a move up and down shift wet base during have to across two Between (or two groups) hot pressing lower die horizontal rail 8, two (or two groups) hot pressing lower die horizontal rails 8 are separated by a distance to be had to be larger than The width of wet base transfer mould 7a, so two groups of fulcrums of supporting hot pressure mold mounting plate are also just at a distance of larger, hot pressing lower die installation Plate central point compressive deformation is maximum.In addition, original same category of device of supporting part is not completely by track stress, track is easy to become Shape, service life are short, and mold mounting plate is not easy holding level under hot pressing, to influence left hot pressing upper mold 3a and left hot pressing lower die The mold depth of parallelism between 3c, right hot pressing upper mold 4a and right hot pressing lower die 4c, also affect hot pressing lower die move horizontally it is steady Property.

Lower-left mould horizontal drive mechanism contains Left Drive device and servo motor 12, and the Left Drive device can be a pair The left rack gear 5a and left gear 5b being meshed are also possible to the screw pair being made of left lead screw 5.1 and left nut 5.2 etc. biography Motivation structure；Bottom right mould horizontal drive mechanism 6 contains right transmission device and servo motor 12, and the right transmission device can be a pair The right rack gear 6a and right gear 6b being meshed are also possible to the screw pair being made of right lead screw 6.1 and right nut 6.2 etc. biography Motivation structure.

When the Left Drive device is a pair of left rack gear 5a and left gear 5b being meshed, the right transmission device is a pair of When the right rack gear 6a and right gear 6b that are meshed, lower-left mould horizontal drive mechanism 5 drive left hot pressing lower die to be horizontally moved with And bottom right mould horizontal drive mechanism 6 drives that be horizontally moved with right hot pressing lower die realized by the transmission of gear and rack gear , what it is with moving gear rotation is servo motor.As shown in figure 3, mold mounting plate 4e under mold mounting plate 3e and right hot pressing under left hot pressing It is respectively fixed with left rack gear 5a and right rack gear 6a, left rack gear 5a is fixed together with mold mounting plate 3e under left hot pressing, can be along heat Pressure mould horizontal rail 8 makees horizontal reciprocating movement, and right rack gear is fixed together with mold mounting plate 4e under right hot pressing, can be along hot pressing Lower die horizontal rail 8 makees horizontal reciprocating movement；Left gear and right gear are respectively positioned on the right of the lower bearing bracket left side and lower bearing bracket, left Gear and left rack gear 5a are meshed, and right gear and right rack gear 6a are meshed, and left gear rotation can drive left rack gear to make left and right horizontal Movement, so that mold mounting plate 3e under left hot pressing be driven to move horizontally, right gear rotation can drive right rack gear left right horizontal movement, To drive mold mounting plate 4e under right hot pressing to move horizontally；It is also possible to mold mounting plate 3e and right hot pressing lower die peace under left hot pressing Left gear and right gear is located in loading board 4e respectively, and left rack gear 5a and right rack gear 6a are separately fixed at the lower bearing bracket left side and lower bearing bracket The right, left gear and left rack gear 5a are meshed, and right gear and right rack gear are meshed, and left gear is performed relative motion with left rack gear 5a can Mold mounting plate 3e under left hot pressing is driven to move horizontally, right gear is performed relative motion with right rack gear 6a can drive right hot pressing lower die to pacify Loading board 4e is moved horizontally, drive left gear and right gear rotation be servo motor.When left hot pressing lower die is (or under right hot pressing Mould) when being moved horizontally to underface (the wet base transfer station 7.1) of wet base transfer mould, it is desirable that the position of stopping is very accurate, no Then, when wet base transfer mould is moved down wet base feeding left hot pressing lower die (or right hot pressing lower die), wet base transfer mould and left hot pressing lower die (or right hot pressing lower die) horizontal position will have deviation, and wet base is easy to produce breakage.Equally, the left hot pressing after having received wet base Lower die also requires the position stopped very accurate when returning to underface (the left hot pressing station 3.1) of left hot pressing upper mold, receive When right hot pressing lower die after wet base returns to underface (the right hot pressing station 4.1) of right hot pressing upper mold, the position stopped also being required Very accurate, otherwise, when the molding of left thermocompression forming device 3 and the molding of right thermocompression forming device 4, the product produced also holds It is also easy to produce breakage.

So mold mounting plate 3e and the right hot pressing lower die peace equipped with right hot pressing lower die under the left hot pressing equipped with left hot pressing lower die The repeatable accuracy of position location when loading board 4e stops in the horizontal direction is particularly significant, in order to ensure yield, it is desirable that has faster Horizontal movement velocity, and start and stop, it is required that there is slow horizontal movement velocity, horizontal movement velocity will accomplish speed Conversion is steady and can accurately and effectively be controlled.In existing equipment, by the left hot pressing equipped with left hot pressing lower die of oil cylinder pushing Mold mounting plate 4e under the right hot pressing equipped with right hot pressing lower die of lower mold mounting plate 3e and oil cylinder pushing, mobile speed in the horizontal direction Degree vibrates larger when converting at a slow speed fastly, cannot accomplish stable position at a slow speed.By repetition test, using the driving of servo motor And this scheme of elastomeric element is filled under hot pressing between mold mounting plate and sliding block 9, it can effectively realize that mold mounting plate 3e exists under left hot pressing The positional accuracy of left hot pressing station 3.1 and wet base transfer station 7.1, and effectively realize mold mounting plate 4e under right hot pressing and exist The positional accuracy of right hot pressing station 4.1 and wet base transfer station 7.1.

Because mold mounting plate can float or move down under hot pressing during the work time.As shown in Fig. 2, Fig. 5, Fig. 5 .1, to ensure Wheel and rack is meshed, the gear shaft (or perhaps center line of gear) of left gear and right gear, vertical to arrange, to adapt to Under hot pressing mold mounting plate float or move down and the displacement that generates.Alternatively, with one kind adapt under hot pressing mold mounting plate float or under The mechanism of shifting ensures that wheel and rack is not interfered with each other in die sinking and molding.
