Description

Technical Field

[0001] The utility model relates to the technical field of mold opening and locking equipment, in particular to a structure for reducing the mold adjustment stroke of a two-plate pressing machine. Background Art

[0002] For the current two-platen press, when the movable platen is moved, the movable platen is disengaged from the tie rod, and when the high-pressure mold is locked, the movable platen is locked with the tie rod. This mechanism is the brake mechanism. Usually, one tie rod is equipped with a set of brake mechanisms, which are composed of an upper brake block and a lower brake block. The upper and lower brake blocks are opened and closed to achieve the clamping.

[0003] Corresponding to different mold thicknesses, in order to make the ring teeth on the inner circle of the brake block mesh with the ring teeth on the outer circle of the pull rod, it is necessary to adjust the relative position of the pull rod and the brake mechanism fixed on the movable template. This is usually accomplished by the clamping mechanism. Therefore, the stroke of the clamping mechanism must be increased by at least one tooth pitch length, and as the clamping force of the pressing mechanism increases, the tooth pitch will also be larger, and the increased stroke will also be larger, resulting in an increase in the size of the clamping mechanism and an increase in cost.

[0029] The present embodiment provides a structure for reducing the mold adjustment stroke of a two-plate pressing machine, which comprises a movable mold plate 1, a pull rod 2, an adjustment pad 3 and a brake mechanism 4. An adjustment pad 3 is added between the movable mold plate 1 and the brake device 4. The adjustment pad 3 is divided into two semicircular plates. During installation, the fixing bolts of the slide rail seat 5 are loosened, and the adjustment pad 3 can be directly inserted between the brake mechanism 4 and the movable mold plate 1 from the upper and lower directions. Then, the fixing bolts of the slide rail seat 5 are tightened to fix the adjustment pad 3 and the brake mechanism 4, so as to change the relative position between the brake mechanism 4 and the pull rod 2 so that it is closer to the meshing position. The mold locking mechanism outside the brake mechanism needs to be adjusted less, thereby achieving the purpose of reducing the stroke of the mold locking mechanism. Not only can the mold locking mechanism stroke be reduced, but the size and cost of the mold locking mechanism are greatly reduced. The adjustment pad can also play a lubricating role, making the operation of the brake mechanism 4 smoother and more stable. The adjustment pad 3 is easy to replace, and the brake mechanism 4 does not need to be removed during the adjustment process, so maintenance and replacement are simple and convenient.

[0030] In a further feasible embodiment of the present invention, the movable template 1 is provided with a plurality of connecting grooves, and a pull rod 2 is matched inside each connecting groove.

[0031] In this embodiment, when the pull rod 2 moves the movable platen 1, the movable platen 1 and the pull rod 2 are disengaged, and when the high-pressure mold is locked, the movable platen 1 and the pull rod 2 are locked.

[0032] In a further possible implementation of this embodiment, the pull rod 2 passes through the movable template 1 and then passes through the hollow cavity 31 and the brake mechanism 4 in sequence.

[0033] The brake mechanism 4 in this embodiment is used to lock the movable platen 1 and the tie rod 2 during high-pressure mold clamping, thereby locking the positions of the movable platen 1 and the tie rod 2.

[0034] In a further implementable embodiment of the present invention, a locking hole is formed through the surface of the adjustment pad 3, a slide rail seat 5 is formed on the outer surface of the brake mechanism 4, and a fixing bolt is formed inside the slide rail seat 5 and matched with the locking hole.

[0035] The fixing bolts on the inner side of the slide rail seat 5 in this embodiment fix the adjustment pad 3 and the brake mechanism 4. The number of the adjustment pads 3 can be adjusted and then locked and positioned to change the relative position between the brake mechanism 4 and the pull rod 2 to make it closer to the meshing position.

[0036] In a further feasible embodiment of the present invention, the adjusting pad 3 is made of a wear-resistant material, the adjusting pad 3 is configured as two semicircular blocks that fit closely together, and the surface of the adjusting pad 3 is coated with lubricating liquid.

[0037] The adjustment pad 3 in this embodiment can be made of wear-resistant material such as a wear-resistant sheet, and lubricating fluid can be added to make the upper and lower brake blocks of the brake mechanism 4 move more smoothly. When replacing the adjustment pad 3, there is no need to remove the brake mechanism 4, and maintenance and replacement are simple and convenient.

[0038] In a further possible implementation manner of this embodiment, the brake mechanism 4 includes an upper brake block 41 and a lower brake block 42 , and a mold locking mechanism is matched and installed on the outer side of the brake mechanism 4 .

[0039] The holding brake mechanism 4 in this embodiment realizes holding by opening and closing the upper and lower brake blocks.

[0040] Embodiment 2:

[0041] On the basis of the first embodiment, different numbers of adjusting pads 3 are selected and installed between the brake mechanism 4 and the movable plate 1;

[0042] The traditional equipment does not have an adjustment pad, and its clamping mechanism stroke S1 = A + B, where A is the meshing adjustment distance and B is the force stroke of the clamping mechanism during clamping;

[0043] Let the number of adjustment pads 3 be n, n≥1, and the thickness of each adjustment pad 3 is the same, then the pad thickness C=A / (n+1), the maximum adjustment distance of n adjustment pads is nC, that is, nA / (n+1), and accordingly, the meshing adjustment distance required by the clamping mechanism can be reduced by nA / (n+1), and the stroke of the clamping mechanism is S2=A / (n+1)+B;

[0044] If the thicknesses of the multiple adjustment pads 3 are different, then corresponding to different molds, the required meshing adjustment distance can be achieved by combining the multiple pads, that is, the range of the thickness H that can be combined by the multiple adjustment pads 3 is 0<H≤A, and the stroke of the clamping mechanism is S3=A-H+B.

[0045] The adjustment proposed in this embodiment selects different numbers of adjustment pads 3 for installation, and the stroke of the clamping mechanism is reduced, and the minimum clamping force stroke B can be retained, which greatly reduces the size and cost of the clamping mechanism; it can play a lubricating role, making the operation of the brake mechanism 4 smoother and more stable, and the adjustment pads 3 are easy to replace, and the brake mechanism 4 does not need to be removed during the adjustment process.
