Abstract
Description
Technical Field
[0001] The present application relates to the field of mold technology, and in particular to a multi-purpose punching mold. Background Art
[0002] Molds are various molds and tools used in industrial production to obtain the required products through methods such as injection molding, blow molding, extrusion, die casting or forging, smelting, stamping, and stretching. In short, the quality of product molding is closely related to the mold.
[0003] In traditional stamping and punching processes, one product generally corresponds to a set of molds. For example, a product that requires stamping corresponds to a stamping mold, while a product that requires punching corresponds to a punching mold. However, in the production of some sheet metal parts, the two products are highly similar. One of them only requires stamping, while the other may only have an extra notch, that is, a punching step is required. In order to effectively save mold costs, this application aims to improve the mold for this type of product so that a mold can be used for two or even more purposes, thereby reducing mold costs and increasing production profits. Utility Model Content
[0004] The purpose of this application is to provide a multi-purpose punching die to solve at least one of the above technical problems.
[0005] In order to solve the above technical problems, the present application provides a multi-purpose punching die, comprising an upper die assembly and a lower die assembly;
[0006] The lower mold assembly includes a base, a first mold body and a switching module; the first mold body and the switching module are both arranged on the base, and a notch groove is formed on the first mold body, and the notch of the notch groove is close to one side of the switching module;
[0007] The switching module includes a first driving member and a mounting block slidably mounted on the base along a first direction, wherein sliding seats are spaced apart on the mounting block, and a clearance groove is provided between two adjacent sliding seats;
[0008] The upper die assembly is provided with a fixed seat and a pressing die set and a punching die set provided on the fixed seat; the pressing die set is provided with a second die body;
[0009] The switching module is adapted to drive the mounting block to move along a first direction so as to move the mounting block into a first position and a second position. When the mounting block is in the first position, the punching module is adapted to slide with the sliding seat and approach the notch along the second direction to punch the plate. When the mounting block is in the second position, the punching module is adapted to vertically enter the avoidance groove.
[0010] In the above implementation process, the plate to be processed is placed between the upper mold assembly and the lower mold assembly. When the mounting block is in the first position, it can be understood that the sliding seat is just below the slider corresponding to the punching mold assembly. When the upper mold assembly is close to the lower mold assembly, the second mold body in the pressing mold assembly of the upper mold assembly cooperates with the first mold body on the lower mold assembly to complete the stamping part, and the plate is stamped and shaped. At the same time, since the sliding seat is just below the slider of the punching mold assembly at this time, the punching mold assembly cannot move further downward. With the cooperation of the inclined wedge unit, the vertical movement will be converted into lateral movement. This can be understood as the slope cooperation between conventional wedge blocks, which can convert the movement in the resin direction into lateral movement. Similarly, in this scheme, due to the obstruction of the sliding seat, the wedge module can play a role, and then the vertical force can be converted into the formation of further movement along the sliding seat, and finally the cutter body on the cutting mold assembly moves along the notch near the notch groove on the first mold body. The cutter body cooperates with the notch to achieve punching, and finally completes the punching and punching processes at the same time, and the product also has a corresponding notch at this time; when the mounting block is in the second position, at this time, when the upper mold assembly moves downward and approaches the lower mold assembly, what is under the slider is not the sliding seat, but the avoidance groove or the empty position next to the mounting block, that is, as the upper mold assembly is further pressed downward, the slider on the punching die group will not be blocked, so the wedge die will not play a role, and finally the cutter body will always show a vertical downward movement, and will not approach the notch part. In this case, when only the pressing die is in effect, the final product will not have a corresponding notch; in this solution, the sliding cooperation between the punching die and the sliding seat is cleverly utilized, and the first driving member is used to realize the switching of the sliding seat position, and finally the punching die presents two different actions, so that the punching action is performed or not performed, and finally the same set of modules can be used to produce two different products, effectively saving mold costs.
[0011] Preferably, the sliding seat is provided with an inverted V-shaped slide rail, the slide rail is arranged at an angle and has a side close to the notch as the lowest point;
[0012] In the above implementation process, the slider on the punching module is adapted to the inverted V-shaped slide rail on the sliding seat. When the two slide together, with the cooperation of the inclined wedge unit, the slider slides along the slider, thereby making the cutter body close to the notch to achieve punching.
[0013] Preferably, a limiting block is provided on one side of the mounting block, and an L-shaped limiting plate is provided on the punching module, and the L-shaped limiting plate is suitable for abutting against the bottom surface of the limiting block;
[0014] In the above implementation process, when the mounting block is in the first position, the punching module is suitable for looking at the gold notch along the second direction, and during its movement, the inner wall of the lower end of the L-shaped limit plate will abut against the bottom surface of the limit block to achieve limitation, which can make the movement of the punching module more stable and improve the accuracy of punching.
[0015] Preferably, a positioning block is provided on the base, and a positioning groove adapted to the positioning block is provided on the upper mold assembly;
[0016] In the above implementation process, a positioning block is provided on the base. When the upper mold assembly is pressed down close to the lower mold assembly, the positioning block cooperates with the positioning groove to make the upper mold assembly and the lower mold assembly dock more accurately.
[0017] Preferably, a plurality of positioning blocks are arranged around the first mold body.
[0018] Preferably, the first driving member includes a driving cylinder.
[0019] Compared with the prior art, the beneficial effect of the present application lies in that: this solution cleverly utilizes the sliding cooperation between the punching module and the sliding seat, and uses the first driving member to realize the switching of the sliding seat position, and finally makes the punching module present two different actions, so that the punching action is performed or not, and finally the effect of producing two different products with the same set of modules can be achieved, effectively saving the mold cost.

[0037] In order to further understand the content, features and effects of the utility model of the present application, the following embodiments are given as examples and described in detail with reference to the accompanying drawings: Example
[0038] In traditional stamping and punching processes, one product generally corresponds to a set of dies. For example, products that require stamping correspond to stamping dies, while products that require punching correspond to punching dies. However, in the production of some sheet metal parts, two products are very similar. One of them only requires stamping, while the other may only have an extra notch, which means that a punching step is required. For details, please refer to Figure 1-2 ,in Figure 1 The product does not need to be punched. Figure 2 The products in the above two sections need to be further punched out. Generally, these two products require a set of corresponding molds for corresponding production. In order to effectively save mold costs, this application aims to improve the mold for this type of product so that a mold can be used for two or even more purposes, thereby reducing mold costs and increasing production profits.
[0039] Specifically, see 3-8. This application provides a multi-purpose punching die, including an upper die assembly and a lower die assembly;
[0040] Specifically, the lower mold assembly includes a base 10, a first mold body 11, and a switching module 20; the first mold body 11 and the switching module 20 are both arranged on the base 10, and a notch groove 111 is formed on the first mold body 11, and the notch of the notch groove 111 is close to one side of the switching module 20;
[0041] Specifically, the switching module 20 includes a first driving member 21 and a mounting block 22 slidably mounted on the base 10 along a first direction. Sliding seats 23 are spaced apart on the mounting block 22, and a clearance groove 24 is provided between two adjacent sliding seats 23.
[0042] Specifically, the upper die assembly is provided with a fixed seat (not shown in the figure) and a pressing die set (not shown in the figure) and a punching die set 30 provided on the fixed seat; the pressing die set is provided with a second die body;
[0043] Specifically, the switching module 20 is adapted to drive the mounting block 22 to move along a first direction so as to move the mounting block 22 into a first position and a second position. When the mounting block 22 is in the first position, the punching module 30 is adapted to slide with the sliding seat 23 and approach the notch along the second direction to punch the plate. When the mounting block 22 is in the second position, the punching module 30 is adapted to vertically enter the avoidance groove 24.
[0044] In the above solution, the plate to be processed is placed between the upper die assembly and the lower die assembly. When the mounting block 22 is in the first position, Figure 5-6 At this time, it can be understood that the sliding seat 23 is just below the slider 32 corresponding to the punching die 30. When the upper die assembly approaches the lower die assembly, the second die body in the pressing die of the upper die assembly cooperates with the first die body 11 on the lower die assembly to complete the stamping part, and the plate is stamped and shaped. At the same time, since the sliding seat 23 is just below the slider 32 of the punching die 30, the punching die 30 cannot move further downward. With the cooperation of the inclined wedge unit, the vertical movement will be converted into lateral movement, which can be understood here as the movement between conventional wedge blocks. The slope of the resin can be matched to convert the movement in the direction of the resin into a lateral movement. Similarly, in this solution, due to the obstruction of the sliding seat 23, the wedge-shaped module can play a role, and then the force in the vertical direction can be converted into the formation of further movement along the sliding seat 23, and finally the cutter body 31 on the cutter module moves along the notch close to the notch groove 111 on the first mold body 11. The cutter body 31 cooperates with the notch to achieve punching, and finally the stamping and punching processes are completed at the same time. At this time, the product also has a corresponding notch; when the mounting block 22 is in the second position, see Figure 7-8The cam 24 is pressed against the bottom of the workpiece 32 and the sliding seat 23 is moved downwards to allow the workpiece 32 to move downwards and out of the way so that the workpiece 32 can be moved downwards.
[0045] It should be noted that although the pressing die and the inclined wedge unit are not shown in the accompanying drawings in this solution, it does not affect the technical personnel in this field to understand the overall solution of this solution; wherein, the second die body on the pressing die group cooperates with the first die body 11 on the base 10 to complete the stamping, and this part of the structure belongs to a very conventional technology in the field of mold technology; further, the inclined wedge unit utilizes the principle of slope matching of the wedge block to convert the vertical movement into horizontal and horizontally inclined movement. This part of the technical solution is also a commonly used means in the mold field, so this application will not further elaborate on it, but it should be emphasized that it does not affect the technical personnel in this field to understand the overall solution.
[0046] Specifically, an inverted V-shaped slide rail is provided on the sliding seat 23, and the slide rail is inclined and has the side close to the notch as the lowest point;
[0047] In the above scheme, the slider 32 on the punching module 30 is adapted to the inverted V-shaped slide rail on the sliding seat 23. When the two slide together, with the cooperation of the inclined wedge unit, the slider 32 slides along the slider 32, thereby making the cutter body 31 close to the notch to achieve punching.
[0048] Specifically, a limit block 41 is provided on one side of the mounting block 22, and an L-shaped limit plate 42 is provided on the punching die 30, and the L-shaped limit plate is suitable for abutting against the bottom surface of the limit block 41;
[0049] In the above scheme, when the mounting block 22 is in the first position, the punching module 30 is suitable for viewing the gold notch along the second direction, and during its movement, the inner wall of the lower end of the L-shaped limit plate 42 will abut against the bottom surface of the limit block 41 to achieve limitation, which can make the movement of the punching module 30 more stable and improve the accuracy of punching; it is understandable that when the mounting block 22 is in the second position, due to the misalignment relationship, there is no limiting cooperation between the limit block 41 and the limit plate.
[0050] Specifically, a positioning block 51 is provided on the base 10, and a positioning groove adapted to the positioning block 51 is provided on the upper mold assembly;
[0051] In the above solution, a positioning block 51 is provided on the base 10. When the upper mold assembly is pressed down close to the lower mold assembly, the positioning block 51 cooperates with the positioning groove to facilitate more accurate docking of the upper mold assembly and the lower mold assembly.
[0052] Furthermore, a plurality of positioning blocks 51 are disposed around the first mold body 11 .
[0053] In one embodiment, the first driving member 21 includes a driving cylinder.
[0054] It should be noted that, unless there is any conflict, the embodiments and features in the embodiments of this application can be combined with each other.
[0055] The above description is only a preferred embodiment of the present application and does not constitute any form of limitation to the present application. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present application fall within the scope of the technical solution of the present application.
