Description

Technical Field

[0001] The invention belongs to the field of push block moulds, and in particular relates to an opening adjustment tool for a super-large push block mould. Background Art

[0002] For Figure 3 For the oversized push block mold shown in the figure, when adjusting its opening size, it is difficult to push the mold by hand because the mold itself is heavy and cannot be pushed directly by hand like a small mold. In particular, operators with slightly less strength cannot push the mold at all, and thus cannot complete the adjustment of the mold opening size.

[0003] The traditional method of adjusting the opening size of this type of super-large push block mold is to first Figure 3 Tighten the two screws on the sides of the mold one by one, so that the push blocks on the left and right sides are opened, and the opening of the mold becomes larger. When the mold opening needs to be reduced, push the push blocks on the left and right sides inward by hand to reduce the opening of the mold, and then Figure 4 The two rear stop bars shown in the figure are inserted into the root of the push block and pressed against the large bottom plate step to complete the adjustment of the mold opening size. This is quite cumbersome to adjust the opening. If you encounter an oversized mold, it is still difficult for the operator to push the opening by hand to make it smaller. This not only has low work efficiency, but also makes the adjustment more laborious. Summary of the invention

The two screw mounting seats 7 are respectively arranged on the left and right ends of the upper surface of the long plate 3. The two ends of the screw rod 6 are respectively passed through the left and right screw mounting seats 7 through corresponding bearings, and the left threaded portion and the right threaded portion of the screw rod 6 correspond to the left and right slider grooves 5 respectively, and the left threaded portion and the right threaded portion of the screw rod 6 respectively cooperate with the internal threads of the left and right sliders 1. The motor 8 is drivingly connected to one end of the screw rod 6. The motor 8 drives the screw rod 6 to rotate forward and reverse to drive the left and right sliders 1 to open and close synchronously.

[0026] Furthermore, the screw rod 6 is a forward and reverse rotation screw rod, the directions of the external threads of the left threaded portion and the right threaded portion of the screw rod 6 are opposite, and the directions of the internal threads of the left and right sliders 1 are the same.

[0027] Furthermore, the screw rod 6 is a common screw rod, the directions of the external threads of the left threaded portion and the right threaded portion of the screw rod 6 are the same, and the directions of the internal threads of the left and right sliders 1 are opposite.

[0028] Furthermore, a handle 9 is provided on the upper surface of each short board 4 .

[0029] Furthermore, the two long plates 3 and the two short plates 4 are integrally formed to increase the structural strength of the square frame.

[0030] Furthermore, there is a clearance fit between the lower portion of the slider 1 and the slider slot 5 .

[0031] Furthermore, the minimum center distance between the two fixed guide roller slots 2 on the left and right is not greater than the center distance between the two guide rollers 10 when the push block mold has the smallest opening; the maximum center distance between the two fixed guide roller slots 2 on the left and right is not less than the center distance between the two guide rollers 10 when the push block mold has the largest opening, thereby meeting all opening requirements of the push block mold.

[0033] Furthermore, the driving force of the motor 8 should be sufficient to overcome the self-weight of the push block mold, the friction between the push blocks, and the friction between the push blocks and the large bottom plate.

[0034] Furthermore, a position sensor is provided at the left and right ends of each slider slot 5 for sensing whether the slider 1 has moved to the left and right limit positions of the slider slot 5. The position sensor is connected to the signal of the motor 8 located on the same long board 3 as the slider 1, and provides a feedback signal to the corresponding motor 8. When the motor 8 receives the feedback signal from the position sensor, it stops working immediately to avoid burning out the motor 8 due to continued rotation.

[0035] The working process of this super large push block die opening adjustment tool is as follows:

[0036] See also Figure 2 As shown, place this tool between the two sets of push block dies. Figure 2 A represents the first set of molds, and B represents the second set of molds. Then, the two fixed guide roller slots 2 on the front long plate 3 of the tool are respectively clamped on the two guide rollers 10 of the first set of molds, and at the same time, the two fixed guide roller slots 2 on the rear long plate 3 of the tool are respectively clamped on the two guide rollers 10 of the second set of molds, thereby completing the assembly before opening adjustment.

[0037] If you want to adjust the opening size of the first set of molds, press the button to start the motor 8 on the front long plate 3. The motor 8 will drive the front screw 6 to rotate, further driving the two front sliders 1 to move back and forth synchronously in the slider slots 5, so that the two front fixed guide roller slots 2 drive the left and right push blocks of the first set of molds to open and close synchronously until the opening is adjusted to the size required by the actual product size. Figure 4 The rear stop bar 11 shown in the figure is inserted into the root of the push block 13 and abutted against the step of the large bottom plate 12, thus completing the opening size of one set of molds. Similarly, if the second set of molds is to be adjusted, the motor 8 located on the rear long plate 3 is started by pressing a button, so that the opening size of the second set of molds can be adjusted. If the entire set of push block molds is long, the two motors can be adjusted in turn to adjust the openings of the two sets of molds to be consistent. After the adjustment is completed, the tool is removed, and the push block mold can process products.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
