Like this, mold mounting plate 3e, can under the driving of lower die horizontal drive mechanism 5 under the hot pressing equipped with hot pressing lower die 3c To be horizontally moved between hot pressing station 3.1 and wet base transfer station 7.1, after receiving wet base from wet base transfer station 7.1, Hot pressing lower die 3c is moved to hot pressing station 3.1 under the driving of lower die horizontal drive mechanism 5, with wet base, moving up and down Hot pressing upper mold is moved down and is molded with hot pressing lower die under the driving of hot pressing upper mold Shift cylinder (or pneumohydraulic pressure-cylinder) 3b, heat Press upper mold Shift cylinder (or pneumohydraulic pressure-cylinder) 3b to the hot pressing die in molding state (by hot pressing upper mold and hot pressing lower die group At) applying certain mold clamping force, wet base carries out hot-pressing drying sizing in the hot pressing die of certain temperature and pressure;Work as hot-die After tool completes the hot-pressing drying sizing to wet base, hot pressing die is opened, and the product after dryness finalization can be moved in several ways It walks, subsequent hot pressing lower die 3c returns to wet base transfer station 7.1 and receives wet base, into subsequent cycle;Or hot pressing lower die 3c with Product after dryness finalization returns to wet base transfer station 7.1, and the product after dryness finalization is removed, and is further continued for receiving wet base, into Enter subsequent cycle.
As shown in Fig. 1 .2, Fig. 4, Fig. 5, Fig. 5 .1, Fig. 5 .2, Fig. 5 .3, mold mounting plate can be in hot pressing by sliding block 9 under hot pressing Left and right horizontal is mobile in lower die horizontal rail 8, under hot pressing between mold mounting plate and sliding block 9 equipped with elastomeric element (preferably spring, Other elastomers can be used);Specific method is as shown in Fig. 5, Fig. 5 .1, Fig. 5 .2, Fig. 5 .3.Under hot pressing mold mounting plate and sliding block 9 it Between elastomeric element coupled using spring block 11, spring block 11 contain elastomeric element 11a, spring upper holder block 11b, spring Lower lock block 11c, spring lock block guide pin 11d, spring upper holder block 11b are fixed together with mold mounting plate under hot pressing, spring downward block 11c is fixed together with sliding block 9;Elastomeric element, spring upper holder block are housed between spring upper holder block 11b and spring downward block 11c Spring lock block guide pin 11d is also equipped between 11b and spring downward block 11c, spring lock block guide pin 11d is fixed on spring downward block On 11c, spring upper holder block 11b covers on spring lock block guide pin 11d, can glide along spring lock block guide pin 11d in vertical direction It is dynamic;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 one Positioning is postponed and is held by spring lock block guide pin 11d;So spring upper holder block 11b and spring downward block 11c can be in vertical side To do it is quantitative relative movement but cannot perform relative motion in the horizontal direction.It is compressed when hot pressing die is in die opening state Elastomeric element rebound, spring upper holder block 11b moves up a certain distance under the action of elastic force, then under hot pressing mold mounting plate relative to The position of sliding block and horizontal rail 8 also moves up a certain distance, and mold mounting plate floats referred to as under hot pressing.When hot pressing die is in When molding state, elastomeric element of mold mounting plate under the action of mold clamping force, under hot pressing between mold mounting plate and sliding block under hot pressing It is compressed, the spring upper holder block 11b of mold mounting plate is along spring lock block guide pin 11d slide downward, hot pressing lower die under fixed hot pressing Mounting plate also declines a certain distance relative to the position of sliding block and horizontal rail 8, and referred to as mold mounting plate moves down under hot pressing.? It may is that spring lock block guide pin 11d is fixed on spring upper holder block 11b, spring downward block 11c is covered in spring lock block guide pin 11d On, spring downward block 11c can be slided up and down in vertical direction along spring lock block guide pin 11d, and working principle is same as described above.
As shown in Fig. 5 .1, Fig. 5 .2, when mold mounting plate is in hot pressing station 3.1 under heat, mold mounting plate under heat On the lower bearing bracket of lower section, it is fixed with supporting part 10 (supporting part 10 can be integrally formed with lower bearing bracket), supporting part 10 is at least one Bearing block or one group of idler wheel;The shape of supporting part 10 can be different, and quantity and position carry out reasonable layout as needed. When hot pressing upper mold and hot pressing lower die mold, mold mounting plate is moved down under hot pressing, and supporting part touches corresponding hot pressing simultaneously Lower mold mounting plate;And at this moment, spring upper holder block 11b elasticity of compression component, and along spring lock block guide pin 11d slide downward;Work as heat Pressure mold mounting plate moves down in place and when touching supporting part, also maintains between spring upper holder block 11b and spring downward block 11c Gap;When die sinking, mold clamping force is released, and elastomeric element rebound, spring upper holder block is moved up along spring lock block guide pin 11d, hot pressing Lower mold mounting plate 3e floats.
Like this, when hot pressing upper mold and hot pressing lower die mold at hot pressing station 3.1, under the action of mold clamping force, hot pressing Lower elastomeric element between mold mounting plate and sliding block is compressed, and mold mounting plate moves down under hot pressing, until mold mounting plate is same under hot pressing When touch its corresponding supporting part 10, supporting part carries mold mounting plate under hot pressing, and corresponding spring upper holder block 11b with Gap is also maintained between spring downward block 11c, spring downward block 11c and sliding block 9 are only acted on by the elastic force of elastomeric element, by Power very little, most of mold clamping force are transmitted to supporting part 10.Supporting part 10 is fixed on the lower bearing bracket under hot pressing under mold mounting plate, root According to needing to carry out rational position distribution, it is entirely avoided mold mounting plate stress deformation phenomenon under hot pressing ensure that hot pressing lower die is pacified The level of loading board, and fully ensured that the depth of parallelism of upper/lower die, the situation that whole mold clamping forces are born by sliding block is avoided, thus The service life for extending sliding block, makes equipment run more stable, positioning accuracy is higher.
When hot pressing die is in die opening state, mold mounting plate 3e floats under hot pressing, and mold mounting plate is detached from load-bearing under hot pressing Part 10, and certain distance is kept in vertical direction and supporting part 10, so as to avoid mold mounting plate under hot pressing in horizontal movement Contact with supporting part completely eliminates frictional force of the mold mounting plate in horizontal movement between supporting part, hot pressing under hot pressing Lower die 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, be increased The stationarity of movement and the accuracy of positioning are added.
When the supporting part 10 is one group of idler wheel, hot pressing die is in die sinking and molding, the heat of fixed hot pressing lower die Elastomeric element can also can be equipped with without floating and moving down by depressing mold mounting plate between mold mounting plate and sliding block under hot pressing, Can also there is no elastomeric element;It is such reality when mold mounting plate does not float and moves down under the hot pressing of fixed hot pressing lower die Apply: under hot pressing molding state, same group of idler wheel touches mold mounting plate under corresponding hot pressing simultaneously, roller wheel bearing Mold mounting plate under left hot pressing;Under hot pressing die opening state, mold mounting plate is along hot pressing lower die water under the hot pressing of fixed hot pressing lower die In idler wheel upper direction, mold mounting plate is directly rolled on idler wheel under hot pressing in plate rail road 8, is not required to move up disengaging idler wheel, until Mold mounting plate is moved horizontally along hot pressing lower die horizontal rail 8 and is left above idler wheel completely under hot pressing;Due to mold mounting plate under hot pressing Force of rolling friction very little when rolling on idler wheel, hot pressing lower die can also be greatly reduced along the resistance of horizontal orbital movement, be saved Energy consumption of the mold mounting plate in horizontal movement under hot pressing, increases the stationarity of movement and the accuracy of positioning.
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, mold mounting plate central point compressive deformation is maximum under hot pressing.In addition, not no supporting part is original Same category of device is completely by track stress, and track is easily deformed, the service life is short, and mold mounting plate is not easy holding level under hot pressing, from And influenced the mold depth of parallelism of hot pressing upper mold 3a Yu hot pressing lower die 3c, also affect hot pressing lower die move horizontally it is steady Property.
Lower die horizontal drive mechanism 5 contains transmission device and servo motor 12, and the transmission device can be a pair and mutually nibble The rack gear 5a and gear 5b of conjunction, are also possible to the feed screw nut auxiliary drive gear being made of lead screw 5.1 and nut 5.2 etc..

So the repetition essence of position positioning when mold mounting plate 3e stops in the horizontal direction under the hot pressing equipped with hot pressing lower die It spends particularly significant;In order to ensure yield, it is desirable that have faster horizontal movement velocity, and start and stop, it is required that having slow Horizontal movement velocity;Thus, horizontal movement velocity will accomplish that speed conversion is steady and can accurately and effectively be controlled.It is original In equipment, movement speed in the horizontal direction is vibrated larger when converting at a slow speed fastly, and positioning accuracy is relatively low.By trying repeatedly It tests, using the measure for filling elastomeric element under the driving and hot pressing of servo motor between mold mounting plate and sliding block 9, can effectively realize heat Mold mounting plate 3e is depressed in the positional accuracy of hot pressing station 3.1 and wet base transfer station 7.1.
Since mold mounting plate can be floated or be moved down (as shown in Fig. 1 .1, Fig. 4, Fig. 5, Fig. 5 .1) under hot pressing in the course of work, To ensure that wheel and rack is meshed, gear shaft (or perhaps center line of gear) is arranged vertically, to adapt to hot pressing lower die Mounting plate float or move down and the displacement that generates;Alternatively, adapting to the mechanism that mold mounting plate floats or moves down under hot pressing with a kind of To ensure that wheel and rack is not interfered with each other in die sinking and molding.
As shown in Fig. 4 .1, the transmission device is also possible to the screw pair being made of lead screw 5.1 and nut 5.2 biography Motivation structure.
When the feed screw nut auxiliary drive gear that the transmission device is made of lead screw 5.1 and nut 5.2, under above-mentioned In mould horizontal drive mechanism 5, the kind of drive of screw pair is driven to pass to substitute above-mentioned wheel and rack with servo motor It is dynamic.As shown in Fig. 1 .2, Fig. 4 .1, the lead screw 5.1 equipped with nut 5.2 is rotatably mounted on lower bearing bracket, the axis of lead screw with Hot pressing lower die horizontal rail 8 is parallel, and a nut guide pin 5.4 is fixed on nut 5.2, and the downside of mold mounting plate 3e is solid under hot pressing Surely there is connector 5.5,5.5 sets of connector on nut guide pin 5.4, can slide up and down along nut guide pin 5.4, hot pressing lower die peace Loading board 3e can be slided up and down by 5.5 opposing nut of connector, the floating of mold mounting plate 3e and moved down under hot pressing and not will drive spiral shell Female moves up and down, but the rotation of lead screw can drive nut to move horizontally, and drives the installation of hot pressing lower die by connector 5.5 Plate 3e is moved horizontally.As shown in Fig. 4 .3, it is also possible to fill on the connector 5.5 being fixed together with mold mounting plate under hot pressing There is nut guide pin 5.4, one block of plate with holes is fixed on nut, is covered on nut guide pin 5.4, mold mounting plate passes through connection under hot pressing 5.5 opposing nut of body can slide up and down, and the floating of mold mounting plate not will drive moving up and down for nut with moving down under hot pressing, but silk The rotation of thick stick can drive nut to move horizontally, and drive mold mounting plate under hot pressing to move horizontally by connector 5.5.
