In the initial state, the follower plate 8 and the separation disc 9 are respectively positioned at the end parts of the second chute 301 and the first chute 201, the separation disc 9 is positioned at the side surface of the supporting plate 17 at the end part and is in a coplanar state with the side surface of the supporting plate 17, and because the separation disc 9 is in threaded connection with the base frame 2, the side surface of the separation disc 9 and the side surface of the supporting plate 17 are more stable, meanwhile, in the state, the abutting roller 16 is positioned in a state of being misplaced with the locking block 20, at the moment, when the plastic sucking is carried out, the base frame 2, the separation disc 9, the abutting frame 3 and the follower plate 8 can be matched to compress four edges of materials, after the materials are heated, the base frame 4 can drive the supporting block 401 and the supporting plates 17 to be moved upwards to be flush with the upper end surface of the base frame 2, wherein the supporting block 401 is connected with an external air supply device and a negative pressure device, and air can be blown between the heated materials and the supporting block 401 and the supporting plates 17 when the base frame 4 moves upwards, so that the heated materials can expand until the supporting block 401 and the supporting plates 17 and the upper end surfaces of the supporting plates are flush with the supporting plates and the supporting plates 17.
When the mold cannot be fully covered on the supporting surface due to the size or the number of the molds on the supporting surface, the screw rod 11 can be rotated at this time, so that the threaded sleeve 13 arranged on the screw rod 11 moves along the length direction of the screw rod 11, the separation disc 9 and the follow-up plate 8 are driven to move transversely, when the abutting frame 3 moves downwards to press the materials, the pressing area is reduced, the abutting roller 16 moves along with the threaded sleeve 13 and rolls on the locking blocks 20 in sequence until one or more locking blocks 20 are blocked by the abutting roller 16 after the separation disc 9 and the follow-up plate 8 move to a preset position, and when the bottom plate 4 moves upwards, only the supporting block 401 and the supporting plate 17 connected with the unblocked locking blocks 20 are lifted, so that the materials are pressed and heated, on one hand, the length of the supporting surface is changed, the two parts are automatically matched, the difficulty in adjusting the sucking plastic range when the supporting surface cannot be covered by the mold and the loss of the materials are reduced, and the production benefit is improved.
Wherein, when the bearing length of bearing face is adjusted in this application, in particular, be provided with four sets of bearing boards 17 altogether in this device, under initial condition, because spring 21 is in compressed state, and make the lower surface butt of even frame 19 and bottom plate 4, the upper surface of four sets of bearing boards 17 all is in the state flush with the upper surface of bearing piece 401 this moment, in this state, can place the mould on the bearing face, after the mould is placed, if have great blank region on the bearing face (this region can't satisfy and place a mould again), the accessible rotates lead screw 11 and changes the position of baffle 9 and follower plate 8, in detail, when control lead screw 11 rotates and make baffle 9 and follower plate 8 move, should make the side that the baffle 9 after accomplishing the adjustment keep away from 801 one side and be close to the side of bearing board 17 coplanarity, and make when bearing board 17 upwards move, it can keep sealed sliding's connection state with baffle 9, and avoid at the time of plastic uptake, the inside gap is got into to the negative pressure effect by the two, the inside gap of air is not enough to cause the material difference.
It should be noted that the following conditions should be satisfied for the adjustment of the moving positions of the spacer 9 and the follower plate 8:
firstly, the side surface of the separation disc 9 far away from the heat insulation plate 801 after adjustment is coplanar with the side surface of the bearing plate 17 near the heat insulation plate 801;
secondly, the end support plate 17 can completely cover the end mold, and the end support plate 17 should be made to extend beyond the end mold by a certain distance.
Further (taking fig. 3 as an example), when the abutment roller 16 abuts against each locking block 20 from left to right in turn during movement, and when the abutment roller 16 abuts against the first locking block 20 and the bottom plate 4 rises, the abutment roller 16 will prevent the carrier plate 17 connected to the locking block 20 from moving upward by abutting against the locking block 20, and when the abutment roller 16 abuts against the second locking block 20 and the bottom plate 4 rises, both the first locking block 20 and the second locking block 20 will remain stationary under the cooperation of the two abutting portions 2001, and similarly, when the abutment roller 16 abuts against the third/fourth locking blocks 20, the above-mentioned rule is maintained, and by this arrangement, the carrier plate 17 which is not used can be effectively prevented from rising, and the practicality is simple, wherein the locking blocks 20 at both ends have the locking blocks 20 adjacent thereto on only one side, and therefore the locking blocks 20 at the ends are provided with the abutting portions 2001 on only one side.
Through above-mentioned setting for under the condition that can't make the mould fully full of the bearing face owing to arrange the reason of mould size or quantity on the bearing face in, can change the position of separating disk 9, follower plate 8 and the length of bearing face through rotatory lead screw 11, and make the material by pressfitting, the length of heating and the length automatic matching of bearing face, on the one hand can realize the regulation of plastic uptake area, reduced the loss of material, on the other hand makes the in-process operation degree of difficulty of adjusting littleer, and regulation speed is faster.
