Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a modular assembly structure of a mold. Background Art

[0002] Molds are widely used. Basically, the manufacturing of various products cannot do without molds. Therefore, the demand for molds is also very large. The cost of molds has become an important part that cannot be ignored in product development and manufacturing costs. To reduce the mold cost, for example, manufacturers processing perforated metal plates often design the mold as a structure with replaceable punch pins and / or cutting plates. When dealing with products of different specifications, different punch pins and cutting plates are selected. However, general mold equipment also brings some problems. The main problem is that the disassembly and assembly of replacement parts are relatively cumbersome, the disassembly and assembly speed is slow and time-consuming, and it is easy to lose parts. For this reason, the utility model proposes a relatively modular mold assembly structure, which can reduce the assembly complexity of the mold, improve the assembly efficiency, and avoid the situation of part loss or forgetting to install. Summary of the Utility Model

[0003] In order to solve the above technical problems, the utility model proposes a mold assembly structure with quickly replaceable tools.

[0004] A modular assembly structure of a mold includes an upper mold base, a lower mold base, a punching and blanking component, and an elastic member.

[0005] The upper mold base and the lower mold base are arranged at intervals up and down, and the upper mold base is driven by a driving member to move up and down reciprocally.

[0006] The punching and blanking component includes an attaching needle plate, a blanking plate, a guiding column, and a punch pin. A vertically oriented needle hole is provided in the middle of the attaching needle plate, and guiding holes are provided in the peripheral portion. The blanking plate is arranged opposite to the attaching needle plate and is provided with yielding holes that are aligned with the needle holes one by one. One end of the guiding column is fixedly installed opposite to the blanking plate, and the other end telescopically inserts into the guiding hole of the attaching needle plate. The tip end of the punch pin sequentially inserts into the needle hole and the yielding hole. The attaching needle plate is relatively fixedly installed at the bottom of the upper mold base by screws or quick-installation members, and the bottom of the upper mold base presses the needle head of the punch pin.

[0007] The elastic member is arranged between the upper mold base and the blanking plate.

[0008] The die assembly structure provided by the present utility model forms a relatively modular punching and blanking component with the needle-attaching plate, the stripping plate, the guide post, and the punching needle. When replacing the punching needle, this module can be removed from the die as a whole. After replacing the punching needle, the entire module is reinstalled, so that there is no need to separately disassemble and assemble the components that block the punching needle one by one. This not only improves the speed and simplicity of replacing the punching needle, but also is not prone to component loss or forgetting to install.

[0009] Preferably, the elastic member is fixedly installed relative to the upper die base or the stripping plate.

[0010] Preferably, the elastic member is a spring or a columnar elastic rubber, which can not only ensure the realization and completion of the punching and blanking work, but also play a role in maintaining the stability of the upper die base and the punching and blanking component.

[0011] Preferably, the top of the needle-attaching plate is flat, and a receiving groove is provided at the position of the needle hole. The depth of the receiving groove is equal to the height of the needle tip of the punching needle, so that the upper die base can provide a stable and reliable supporting effect for the needle-attaching plate, and at the same time, it can press the punching needle.

[0012] Preferably, to achieve the flexibility of the number of punching needles used, a sliding groove is provided at the bottom of the upper die base corresponding to the row of needle holes. A long strip-shaped thimble slider is slidably arranged in the sliding groove, and the bottom end of the thimble slider abuts against the needle tip of the punching needle. The length of the thimble slider inserted into the sliding groove depends on the number of punching needles to be enabled in the sliding groove, so that different numbers of mesh holes can be processed without removing the punching needles.

[0013] Preferably, a cutting edge plate is provided on the top of the lower die base, and a shock-absorbing backing plate is padded at the bottom of the cutting edge plate, which can reduce the vibration generated during punching, improve the punching quality, and also avoid the situation of needle breakage.

[0014] Preferably, a vertical guiding structure is provided between the lower die base and the upper die base or the punching and blanking component, which can improve the direction stability during punching and avoid slipping and needle breakage.

[0015] Preferably, the guiding structure includes a guiding rod provided on the cutting edge plate and a guiding channel provided on the punching and blanking component, with a simple structure and good guiding effect.

[0016] Preferably, the guiding channel is provided at the bottom end of the guiding post, which can streamline the mechanism and avoid occupying too much space on the punching and blanking component to open holes. At the same time, by improving the accuracy of the coaxiality of the guiding channel and the guiding post, the consistency of the internal guiding of the punching and blanking component and the external guiding between the punching and blanking component and the lower die base can be improved, and the punching accuracy can be improved.

[0017] Preferably, the lower die base and the upper die base are made of cast iron material, which is not easy to deform and has good vibration absorption effect.

[0018] As can be seen from the above description of the present invention, the present invention has the following beneficial effects:

[0019] The mold assembly structure provided by the present invention forms a relatively modular punching and blanking component by the needle-attaching plate, the stripping plate, the guide post and the punching needle. When replacing the punching needle, this module can be integrally disassembled from the mold. After replacing the punching needle, the whole module is reinstalled, so that there is no need to separately disassemble and assemble the parts blocking the punching needle one by one. This not only improves the speed and simplicity of replacing the punching needle, but also is not easy to have the situation of part loss or forgetting to install.

[0020] The elastic member is a spring or a columnar elastic rubber, which can not only ensure the realization and completion of the punching and blanking work, but also play a role in maintaining the stability of the upper die base and the punching and blanking component.

[0021] The bottom of the upper die base is provided with a chute corresponding to the row of needle holes. A long strip-shaped thimble slider is slidably arranged in the chute, realizing the flexibility of the number of punching needles used, and different numbers of mesh holes can be processed without taking out the punching needles.

[0022] A vertical guiding structure is arranged between the lower die base and the upper die base or the punching and blanking component, which can improve the direction stability during punching, and avoid the situations of slipping and needle breaking.

[0023] The guiding channel of the above-mentioned guiding structure is arranged at the bottom end of the guiding post, which can streamline the mechanism and avoid occupying too much space on the punching and blanking component to open holes. At the same time, by improving the accuracy of the coaxiality of the guiding channel and the guiding post, the consistency of the internal guiding of the punching and blanking component and the external guiding between the punching and blanking component and the lower die base can be improved, and the punching accuracy can be improved.

Specific implementation manner

[0032] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present utility model clearer and more understandable, the present utility model will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present utility model and are not used to limit the present utility model.

[0033] Please refer to Figures 1 to 4 , a modular assembly structure of a mold, including an upper die holder 1, a lower die holder 2, a punching and stripping component 3 and an elastic member 4.

[0034] The upper die holder 1 and the lower die holder 2 are arranged at intervals up and down, and the upper die holder 1 is driven by a driving member to move up and down reciprocally.

[0035] The punching and stripping component 3 includes a needle attachment plate 31, a stripping plate 32, a guide post 33 and a punch pin 34. A vertically arranged needle hole 312 is provided in the middle of the needle attachment plate 31, and guide holes are provided in the periphery. The stripping plate 32 is arranged opposite to the needle attachment plate 31 and is provided with relief holes 321 that are aligned with the needle holes 312 one by one. One end of the guide post 33 is fixedly installed opposite to the stripping plate 32, and the other end telescopically inserts into the guide holes of the needle attachment plate 31. The tip end of the punch pin 34 is sequentially inserted into the needle hole 312 and the relief hole 321. The needle attachment plate 31 is relatively fixedly installed at the bottom of the upper die holder 1 by screws or quick-installation parts (using existing quick-installation parts, such as a hydraulic quick-installation structure, which is prior art and not an improvement point of the present utility model, so it will not be elaborated here). The bottom of the upper die holder 1 presses the needle head of the punch pin 34. In this embodiment, the top of the needle attachment plate 31 is flat, and an accommodation groove 311 is provided at the position of the needle hole 312. The depth of the accommodation groove 311 is equal to the height of the needle head of the punch pin 34, so that the upper die holder 1 can provide a stable and reliable supporting effect for the needle attachment plate 31, and at the same time, can press the punch pin 34.

[0036] In another embodiment, to achieve flexibility in the number of punch pins 34 used, a sliding groove 11 is provided at the bottom of the upper die base 1 corresponding to the row of needle holes 312. A strip-shaped ejector slider 12 is slidably provided in the sliding groove 11. The bottom end of the ejector slider 12 abuts against the tip of the punch pin 34. The length of the ejector slider 12 inserted into the sliding groove 11 depends on the number of punch pins 34 to be enabled in the sliding groove 11. Thus, different numbers of mesh holes can be processed without removing the punch pins 34.

[0037] The elastic member 4 is disposed between the upper die base 1 and the stripper plate 32. In this embodiment, the elastic member 4 is fixedly installed relative to the stripper plate 32, and the other end is snapped into a limiting groove provided at the bottom of the upper die base 1. Preferably, the elastic member 4 is a spring or a columnar elastic rubber, which can not only ensure the realization and completion of the punching and material stripping operations, but also play a role in maintaining the stability of the upper die base 1 and the punching and material stripping assembly 3.

[0038] A cutting edge plate 5 is provided at the top of the lower die base 2, and a shock-absorbing backing plate 6 is padded at the bottom of the cutting edge plate 5, which can reduce the vibration generated during punching, improve the punching quality, and also avoid the situation of broken needles.

[0039] On the basis of the above embodiment, in another embodiment, a vertical guiding structure is provided between the lower die base 2 and the upper die base 1 or the punching and material stripping assembly 3, which can improve the directional stability during punching and avoid the situations of slipping and broken needles. Preferably, the guiding structure includes a guiding rod 7 provided on the cutting edge plate 5 and a guiding channel 331 provided in the punching and material stripping assembly 3, which has a simple structure and good guiding effect.

[0040] In addition, the mechanism can be streamlined. In a specific embodiment, the guiding channel 331 is provided at the bottom end of the guiding column 33, which avoids occupying too much space on the punching and material stripping assembly 3 to open holes. At the same time, by improving the coaxiality accuracy of the guiding channel 331 and the guiding column 33, the consistency of the internal guiding of the punching and material stripping assembly 3 and the external guiding between the punching and material stripping assembly 3 and the lower die base 2 can be improved, and the punching accuracy can be improved.

[0041] The mold assembly structure provided by the present utility model forms a relatively modular punching and material stripping assembly 3 with the needle-attached plate 31, the stripper plate 32, the guiding column 33, and the punch pin 34. When replacing the punch pin 34, this module can be integrally disassembled from the mold. After replacing the punch pin 34, the entire module is then installed, so that there is no need to separately disassemble and assemble the components that block the punch pin 34 one by one. This not only improves the speed and simplicity of replacing the punch pin 34, but also is not likely to have the situation of component loss or forgetting to install.
