Description

Technical Field

[0001] This utility model belongs to the technical field of molds, specifically relating to an integrated molding and cutting mold. Background Technology

[0002] The production process of sheet products includes pressing and forming the product, as well as edge trimming. In existing technology, these two processes require two sets of molds: a product forming mold and an edge trimming mold. Specifically, first, the sheet is placed in the product forming mold and stretched into a product with a certain shape. Then, the product is placed in the edge trimming mold to cut off the sheet edge. The problem is that the two sets of molds require two operating positions. Specifically, the two sets of molds need to be installed on two separate machines, and two operators are required to operate them. This increases the labor cost and equipment operating cost of the product, raises the production cost, and reduces the product's competitiveness in the market. Furthermore, the product needs to be transferred between the two processes, which takes time, increasing the processing time and reducing the production efficiency.

[0003] Therefore, further improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to overcome at least one of the shortcomings of the prior art and provide an integrated forming and cutting mold that can simultaneously stretch and form products and cut off edge materials, thereby reducing the production cost of products and improving the production efficiency of products.

[0005] To achieve the above objectives, the technical solution provided by this utility model embodiment is as follows:

[0006] A molding and cutting integrated mold includes an upper mold assembly and a lower mold assembly that are corresponding to each other.

[0007] The upper mold assembly includes an upper template, and an upper cutting punch and an upper forming punch disposed on the upper template, wherein the upper cutting punch and the upper forming punch are arranged sequentially from top to bottom;

[0008] The lower mold assembly includes a lower template and a lower die disposed on the lower template and corresponding to the upper cutting punch and the upper forming punch;

[0009] When the upper mold assembly and the lower mold assembly cooperate with each other, firstly, the upper forming punch and the lower die cooperate to stretch the sheet material and form a product, and then the upper cutting punch and the lower die cooperate to cut the edge material of the sheet material from the product.

[0010] The upper cutting punch is fastened to the bottom surface of the upper template, the upper forming punch is fastened to the bottom surface of the upper cutting punch, the central axis of the upper cutting punch and the upper forming punch coincide, and the lower die is a through hole and is integrally formed with the lower template.

[0011] The outer wall dimension of the upper cutting punch is equivalent to the inner wall dimension of the lower die, and the Rockwell hardness of the upper cutting punch is 60 HRC.

[0012] There is a certain gap between the outer wall of the upper forming punch and the inner wall of the lower die, the gap being H, where 0.2mm < H < 0.4mm, and the Rockwell hardness of the upper forming punch is 45HRC.

[0013] The lower mold assembly is provided with positioning components. There are two positioning components, which are located on the top surface of the lower mold plate and on the left and right sides of the lower die.

[0014] The upper cutting punch and the upper forming punch are several in number and are arranged at intervals along the left and right direction of the upper template. The lower die is several in number and is arranged at intervals along the left and right direction of the lower template.

[0015] A guide structure is provided between the upper mold assembly and the lower mold assembly.

[0018] The lower mold assembly also includes a lower mold base, which is disposed on the bottom surface of the lower mold plate. The lower mold base is provided with an unloading port for unloading material, which is provided corresponding to the lower die cavity.

[0019] The beneficial effects of this utility model are as follows:

[0020] This utility model, through the adoption of the above-mentioned integrated forming and cutting mold, enables the sheet material to be stretched and formed into a product while being placed in the mold, and the edge material of the sheet material to be cut off from the product. Only one operator is needed to complete the two processes of product forming and edge material cutting, which reduces the number of processing molds, operators, and equipment used, thereby reducing the labor cost and equipment operating cost of the product, reducing the production cost of the product, and improving the product's competitiveness in the market.

[0030] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are some embodiments of this utility model, but not all embodiments.

[0031] See Figure 1-8This molding and cutting integrated mold includes an upper mold assembly 1 and a lower mold assembly 2, which are corresponding to each other. In this embodiment, the upper mold assembly 1 includes an upper mold base 15, an upper template 11, an upper cutting punch 12, and an upper forming punch 13. The upper cutting punch 12 is fastened to the bottom surface of the upper template 11 by fastening components, and the upper forming punch 13 is fastened to the bottom surface of the upper cutting punch 12 by fastening components. The upper cutting punch 12 and the upper forming punch 13 are arranged sequentially from top to bottom, and their central axes coincide. The upper mold base 15 is fastened to the top surface of the upper template 11 by fastening components. The lower mold assembly 2 includes a lower mold base 24, a lower template 21, and a lower die 22. The lower die 22 is preferably a through hole and is set corresponding to the upper cutting punch 12 and the upper forming punch 13, and is integrally formed with the lower template 21. That is, the upper cutting punch 12, the upper forming punch 13, and the lower die 24 are all integrated into the mold assembly 21. Both molds have the same shape. The lower mold base 24 is fastened to the bottom surface of the lower mold plate 21 by fastening components. When the upper mold assembly 1 and the lower mold assembly 2 cooperate with each other, firstly, the upper forming punch 13 extends downward into the lower die 22 and the two cooperate with each other to stretch the sheet material and form a product with a relevant shape. Then, the upper cutting punch 12 extends downward into the lower die 22 and the two cooperate with each other to cut the sheet material edge from the product. The mold has both stretching and forming and edge cutting processes, so that the sheet material can be stretched and formed into a product and the sheet material edge can be cut off from the product at the same time when it is placed in the mold. Only one operator is needed to complete the two processes of product forming and edge cutting, which reduces the number of processing molds, operators and equipment, reduces the labor cost and equipment operating cost of the product, reduces the production cost of the product, and improves the competitiveness of the product in the market.

[0032] In addition, the product does not need to be moved during the product forming and edge trimming processes, which reduces the product transfer time and can reduce the product processing time to a certain extent, thereby improving the product production efficiency.

[0033] Furthermore, in this embodiment, the outer wall size of the upper cutting punch 12 is comparable to the inner wall size of the lower die 22, and the Rockwell hardness of the upper cutting punch 12 is 60 HRC. Specifically, the outer wall size of the upper cutting punch 12 is slightly smaller than the inner wall size of the lower die 22 so that the upper cutting punch 12 can extend downward into the lower die 22 to cut the sheet material. The hardness of the upper cutting punch 12 is increased to 60 HRC through heat treatment methods such as quenching, tempering, and surface hardening, which increases the surface hardness of the upper cutting punch 12 and improves its service life, as can be understood by those skilled in the art.

[0034] Furthermore, in this embodiment, there is a certain gap between the outer wall of the upper forming punch 13 and the inner wall of the lower die 22, the gap being H, where 0.2mm < H < 0.4mm. The Rockwell hardness of the upper forming punch 13 is 45 HRC, specifically, H is preferably 0.3mm, so that the upper forming punch 13 can extend downward into the lower die 22 to stretch the sheet. The hardness of the upper forming punch 13 is increased to 45 HRC through heat treatment methods such as tempering. While ensuring the forming function of the upper forming punch 13, the production cost of the upper forming punch 13 can be reduced to a certain extent, thereby reducing the production cost of the mold, which can be understood by those skilled in the art.

[0035] Furthermore, the lower mold assembly 2 is provided with positioning components 25. Specifically, in this embodiment, the positioning components 25 are preferably positioning pins, and the number of them is preferably two. They are detachably inserted into the top surface of the lower template 21 and located on the left and right sides of the lower die 22. Through the above technical solution, when the sheet is placed on the lower mold assembly 2, the positioning components 25 can position the sheet on the lower template 21, avoiding the sheet from shifting to the left and right during processing, and improving the processing accuracy of the product to a certain extent. This is understandable to those skilled in the art.

[0036] Furthermore, in this embodiment, the number of upper cutting punches 12 and upper forming punches 13 is preferably four, and they are arranged at intervals along the left and right direction of the upper template 11. The number of lower die 22 corresponding to the number of upper cutting punches 12 and upper forming punches 13 is preferably four, and they are arranged at intervals along the left and right direction of the lower template 21. Through the above technical solutions, the mold can process multiple products at the same time in one operation, which further improves the processing efficiency of the products. This is understandable to those skilled in the art.

[0037] Furthermore, a guide structure is provided between the upper mold assembly 1 and the lower mold assembly 2. Specifically, in this embodiment, the guide structure includes a guide sleeve 14 and a guide post 23. The guide sleeve 14 is disposed through the upper template 11 from top to bottom, and the guide post 23 is disposed through the lower template 21 from bottom to top. When the upper mold assembly 1 and the lower mold assembly 2 cooperate with each other, the guide post 23 extends into the guide sleeve 14 and the two slide against each other. The upper mold assembly 1 moves relative to the lower mold assembly 2 in the vertical direction of the mold. Through the above technical solution, when the upper mold assembly 1 and the lower mold assembly 2 cooperate with each other, the horizontal position between the upper mold assembly 1 and the lower mold assembly 2 can be guaranteed, so that the upper cutting punch 12 and the upper forming punch 13 can be precisely matched with the lower die 22, further improving the processing accuracy of the product. This is understandable to those skilled in the art.

[0038] Furthermore, in this embodiment, the guide structure is preferably in four sets and is respectively set at the four corners of the mold. Through the above technical solution, the horizontal position between the upper mold assembly 1 and the lower mold assembly 2 is further guaranteed, and the vertical movement of the upper mold assembly 1 relative to the lower mold assembly 2 can be more stable, which can be understood by those skilled in the art.

[0039] Furthermore, the lower mold base 24 is provided with a discharge port 241. Specifically, in this embodiment, the number of discharge ports 241 is preferably one, which is arranged vertically through the lower mold base 24 and corresponds to the lower die 22. After the product is processed, it is discharged from the mold through the lower die 22 and the discharge port 241 in sequence. Through the above technical solution, the product can be automatically discharged from the mold without manual operation, reducing the time for manual unloading and further improving the production efficiency of the product. This can be understood by those skilled in the art.

[0040] The above describes the preferred embodiments of this utility model, illustrating and describing its basic principles, main features, and advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made without departing from the spirit and scope of this utility model, and all such changes and modifications fall within the scope of protection of this utility model as defined by the appended claims and their equivalents.
