Description

Technical Field

[0001] The utility model relates to a hook mould structure and belongs to the technical field of processing moulds. Background Art

[0002] The description in this section merely provides background information related to the disclosure of the present utility model and does not constitute prior art.

[0003] With the development of science and technology, the market has higher and higher requirements for hardware products, and product updates are faster and faster with lower prices. Therefore, the requirements for mold structure are becoming more and more complex, which has directly led to a wide variety of existing mainstream mold models. At the same time, the mold inserts require quick disassembly, and it is necessary to easily change models and repair molds on the punch press, which places higher requirements on the simplicity of mold maintenance.

[0004] The traditional method of mold maintenance is generally to remove the mold structure from the punch press, move it to the mold assembly workshop, and then disassemble the mold to change the model or repair the punch parts. Generally, the equal-height sleeve structure is used to fix the multi-layer mold. The replacement speed is slow, and the equal-height sleeve structure is invisible, which is prone to hidden dangers, resulting in a waste of manpower, material resources and precious time, affecting output efficiency.

[0005] There is no hook mold structure that can solve the above problems at present. Utility Model Content

[0006] The purpose of the utility model is to provide a hook mold structure, which is simple in structure, stable and easy to use, can realize rapid replacement of mold parts, and improve operability.

[0007] In order to achieve the above-mentioned purpose, the utility model discloses the following hook mold structure, which is used for locking the mold, wherein the mold comprises an upper seat plate, an upper pad plate, an upper clamping plate, a stop plate, an upper stripping plate and a lower mold plate stacked along a first direction; wherein one side of the upper clamping plate comprises a screw hole; and further comprises:

[0008] A hook mechanism, the hook mechanism comprises a body, a limiting groove and a through hole, a plurality of the limiting grooves are arranged on one side of the body, one of the limiting grooves is clamped at one end of the upper clamping plate at an angle not parallel to the first direction, and another limiting groove is clamped at one end of the upper stripping plate at an angle not parallel to the first direction, so that the upper clamping plate, the stop plate and the upper stripping plate are limited by the hook mechanism; the through hole is arranged on one side of the screw hole;

[0009] The locking mechanism includes a nut and a screw, wherein the nut is fixedly arranged on a side of the screw away from the upper clamping plate, and the screw passes through the through hole and is detachably screwed into the screw hole so that the nut abuts against the outer wall of the body at the through hole position.

[0010] Further, the screw hole, the through hole and the screw rod extend along a second direction perpendicular to the first direction.

[0011] Furthermore, the nut includes a hexagonal socket extending along the second direction.

[0012] Furthermore, there are two limiting grooves, and the body between the two limiting grooves is configured to extend parallel to the first direction.

[0013] Further, one end of the body along the first direction abuts against the upper seat plate.

[0014] Furthermore, one end of the body along the first direction fits with one side of the upper seat plate.

[0015] Furthermore, one side of the upper pad and the lower template includes a groove for accommodating the body along the limiting groove.

[0016] By means of the above technical solution, the beneficial effects of the utility model are as follows:

[0017] 1. Compared with the traditional structure of equal height sleeve type, the hook mold structure of the utility model can realize quick disassembly and quick replacement. It only needs to unscrew the locking mechanism of the utility model on one side of the mold to easily remove the entire hook mechanism from one side of the mold, and then quickly replace or repair the punch, insert or upper stripping plate in the mold. The conventional structure of the equal height sleeve type needs to be removed from the punch press and then moved to the mold assembly workshop, and then the mold is disassembled to change the model or repair the punch parts. In comparison, the steps are extremely cumbersome.

[0018] 2. The hook structure of the main body of the hook mold structure of the utility model is arranged on one side of the mold. During the use of the mold, workers can observe the hook mechanism and the locking mechanism in real time, avoiding unnecessary parts loss or even accidental injury due to starting the mold before it is locked or loosened, thereby significantly improving production safety.

The terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances. The following describes the implementation method of the present utility model based on its overall structure.

[0024] See also Figure 1 , is a hook mold structure of the present embodiment, used for locking the mold, wherein the mold comprises an upper seat plate 100, an upper pad plate 200, an upper clamping plate 300, a stop plate 400, an upper stripping plate 500 and a lower mold plate 600 stacked along a first direction; wherein one side of the upper clamping plate 300 comprises a screw hole; and further comprises:

[0025] The hook mechanism 1 comprises a body 11, a limiting groove 12 and a through hole 13, wherein a plurality of limiting grooves 12 are arranged on one side of the body 11, wherein one limiting groove 12 is clamped at one end of the upper clamping plate 300 at an angle not parallel to the first direction, and another limiting groove 12 is clamped at one end of the upper stripping plate 500 at an angle not parallel to the first direction, so that the upper clamping plate 300, the stop plate 400 and the upper stripping plate 500 are limited by the hook mechanism 1; the through hole 13 is arranged on one side of the screw hole 301;

[0026] The locking mechanism 2 includes a nut 21 and a screw 22. The nut 21 is fixedly arranged on a side of the screw 22 away from the upper clamping plate 300. The screw 22 passes through the through hole 13 and is detachably screwed into the screw hole 301 so that the nut 21 abuts against the outer wall of the main body 11 at the position of the through hole 13.

[0027] Through the above structure, when in use, the staff only needs to place the hook mechanism 1 against one side of the mold, so that the limit groove 12 on the hook mechanism 1 is tightly in contact with one side of the upper clamping plate 300 and the upper release plate 500, and then, the locking mechanism 2 can pass through the through hole 13 of the hook mechanism 1 and be screwed into the screw hole 301, tightly buckling the main body 11 on the position of the upper clamping plate 300, the stop plate 400 and the upper release plate 500, so that the upper clamping plate 300, the stop plate 400 and the upper release plate 500 are firmly fixed by the hook mechanism 1, achieving a locking effect similar to the equal-height sleeve structure in the prior art.

[0028] At the same time, since in the above process, the hook mechanism 1 and the locking mechanism 2 of the main body of this embodiment are both arranged at the outer side of the mold, therefore, without the need for workers to disassemble the entire mold, as long as the locking mechanism 2 is twisted out from the outer side of the mold, the stop plate 400 and the upper stripping plate 500 can be easily removed, and the mold can be efficiently replaced or the punch parts can be repaired, thereby improving maintenance efficiency. At the same time, since the hook mechanism 1 and the locking mechanism 2 are both arranged on one side of the mold, during the use of the mold, the worker can observe the hook mechanism 1 and the locking mechanism 2 in real time. Compared with the traditional structure that cannot be directly observed during use, this embodiment can significantly improve the safety of the operation.

[0029] It is worth noting that the mold in this embodiment includes an upper seat plate 100 set at the top, which is mainly used to clamp the mold and the work surface of the press. In the second embodiment, considering the actual cost needs, the upper seat plate 100 may not be set without special needs. At the same time, in this embodiment, the stop plate 400 may not be set. The function of the stop plate 400 is similar to that of the upper pad 200. It is used to pad the inserts and screws of the upper stripping plate 500 to prevent the gap between the punch and the upper stripping plate 500 from being too large. It may not be set according to the situation. That is to say, in the second embodiment, the hook mechanism 1 clamps two layers of the upper clamping plate 300 and the upper stripping plate 500. Of course, in other specific embodiments, the specific components in the mold can be customized according to specific usage requirements, but the hook mechanism 1 can clamp and cover the range beyond the upper clamping plate 300 and the upper stripping plate 500, and the locking mechanism 2 is also fixedly connected to the position of the upper clamping plate 300. The above range is equivalent to the extended embodiment of the technical features of the utility model.

[0030] Specifically, the screw hole 301 on one side of the upper clamping plate 300 is arranged toward the outside of the mold, and the screw hole 301 includes a universal model thread, which matches the screw rod 22 of the locking mechanism 2, so that the screw rod 22 can be screwed into and fixed inside the screw hole 301. The length of the screw hole 301 is at least not shorter than the length of the screw rod 22 minus the thickness of the body 11, so that after the screw rod 22 is screwed into the screw hole 301, it can continue to be screwed into the screw hole 301 so that the nut 21 at one end of the screw rod 22 can directly contact one side of the body 11, and the continuous screwing of the screw rod 22 can increase the contact force between the nut 21 and one side of the body 11, thereby strengthening the fixing effect of the hook mechanism 1 in cooperation with the locking mechanism 2 on the mold. The hook mechanism 1 is configured as a regular plate with hooks on both sides, and the limiting grooves 12 are configured at both ends of the body 11, and the body 11 and the limiting grooves 12 are integrally configured, and the two limiting grooves 12 are slightly protruding from the body 11 and hooked on one side of the upper clamping plate 300 and the upper stripping plate 500. The limiting grooves 12 can be configured as U-shaped grooves or L-shaped grooves, as long as the inner contour of the limiting grooves 12 can match one side of the upper clamping plate 300 and the upper stripping plate 500. The through hole 13 on the hook mechanism 1 is configured at the position of the screw hole 301, and specifically, the size of the through hole 13 matches the screw rod 22, so that the through hole 13 at least does not hinder the screw rod 22 from being inserted.

[0031] In another embodiment, the through hole 13 includes an internal thread that matches the thread on the screw 22, so that the screw 22 and the hook mechanism 1 can be threadedly connected, thereby strengthening the fixing effect of the locking mechanism 2 on the hook mechanism 1. Through the fit between the two, the fixing effect of the hook mechanism 1 and the locking mechanism 2 on the mold is also indirectly enhanced, but it may increase a portion of the production cost.

[0032] In this embodiment, a mold periphery includes a total of four symmetrically arranged hook mechanisms 1 and locking mechanisms 2 combinations. Specifically, two hook mechanisms 1 and locking mechanisms 2 are arranged equidistantly on the left and right sides of the mold, which can achieve a relatively stable fixing effect and will not excessively affect the time for removing the locking mechanisms 2. However, in some other embodiments, if there is a larger-sized mold, six or eight hook mechanisms 1 and locking mechanisms 2 combinations can be provided to enhance the stability of the mold fixation of the utility model.

[0033] Furthermore, the screw hole 301, the through hole 13 and the screw rod 22 extend in a second direction perpendicular to the first direction. Specifically, by screwing the screw rod 22 into the hook mechanism 1 and the template in a vertical direction, the best pit torque effect is achieved. At the same time, the nut 21 in this embodiment includes an inner hexagon extending in the second direction, which makes it easier for workers to drive the nut 21 to drive the screw rod 22 to be screwed in and out, further improving the replacement efficiency.

[0034] Further, there are two limit grooves 12, and the body 11 between the two limit grooves 12 is set to extend parallel to the first direction. In this embodiment, one of the limit grooves 12 is set on the top side of the upper clamping plate 300 at the top through a U-shaped groove hook, and the other limit groove 12 is also set on the bottom side of the upper stripping plate 500 through a U-shaped groove hook. The body 11 between the two limit grooves 12 is attached to one side of the upper clamping plate 300, the stop plate 400 and the upper stripping plate 500, but maintains a certain gap with the upper clamping plate 300, the stop plate 400 and the upper stripping plate 500. In the working state of the mold of this embodiment, when changing from the mold opening state to the mold closing state, the stop plate 400, the upper stripping plate 500 and the lower mold plate 600 will be relatively The upper clamping plate 300 will have a short-distance displacement along the first direction, so that the body 11 between the two limit grooves 12 can not hinder the displacement of the stop plate 400 and the upper stripping plate 500 along the first direction.

[0035] Furthermore, one end of the body 11 along the first direction abuts against the upper seat plate 100, and one end of the body 11 along the first direction fits with one side of the upper seat plate 100. Specifically, one end of the body 11 is a rectangular block, one side of the block abuts against the upper seat plate 100, and through the abutment between the block on one side of the body 11 and the upper seat plate 100, the hook mechanism 1 can be more firmly locked and fixed on the mold, further enhancing the stability of the mold.

[0036] Furthermore, one side of the upper pad 200 and the lower template 600 includes a groove 601 for accommodating the body 11 along the limiting groove 12. With the existence of the groove 601 in this embodiment, the hooks on both sides of the body 11 can be hooked on one side of the upper clamping plate 300 and the upper stripping plate 500 with a larger area, and the lower template 600 can not hinder the small displacement of the hook mechanism 1 along the first direction. In other words, during the process of opening and closing the mold, one end of the body 11 can move freely in the groove 601.

The description of the above embodiments is only used to help understand the method and core idea of ​​the present invention. At the same time, for those skilled in the art, according to the idea of ​​the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
