Description

Technical Field

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

[0002] Large-scale component products require vertical and lateral punching processes during the development process of their molds due to their large size and diverse installation locations. The side punching process requires the mold to be separated to obtain a hydraulic side punch module to ensure the accuracy of mold processing and the timeliness of mold assembly and debugging. However, there is a certain error in the vertical wall of the installation surface processed by CNC machine tools. Taking a height of 200MM as an example, the error is about 0.05MM, and the error increases with the increase of height. When the error is large, the assembly of the hydraulic side punch module will interfere with the vertical wall of the installation surface of the mold body, and the module and the side wall will not fit together. Manual grinding and repair of the entire installation surface is required, which prolongs the mold assembly cycle. Therefore, how to reduce the complexity of processing and shorten the mold installation time while ensuring the support strength and fitting accuracy of the fitting surface is a technical problem that needs to be solved. Utility Model Content

By setting an air-avoidance groove at the installation contact surface, a fine strip-shaped fitting surface is obtained, the area of ​​the fine surface is reduced, and the time of assembly work is reduced while ensuring support.

[0004] The purpose of the utility model can be achieved through the following technical solutions:

[0005] According to one aspect of the utility model, a side punch installation structure of a mold is provided, comprising a mold body, a side punch module, a mounting contact surface, a strip-shaped fitting surface and an air avoidance surface. The side punch module and the mold body are connected through the mounting contact surface. A strip-shaped fitting surface and an air avoidance surface are arranged on the mounting contact surface. The strip-shaped fitting surface is arranged along the edge of the mounting contact surface, and the air avoidance surface is obtained by performing air avoidance treatment on the portion other than the strip-shaped fitting surface on the mounting contact surface.

[0006] Furthermore, the air avoidance depth of the air avoidance surface is 1 mm.

[0007] Furthermore, the precision of the air-avoiding surface is 0.05 mm.

[0009] Furthermore, the width of the strip-shaped bonding surface is 20 mm.

[0010] Furthermore, the precision of the strip-shaped laminating surface is 0.01 mm.

[0011] Furthermore, the verticality tolerance of the strip-shaped bonding surface relative to the horizontal bottom surface is ±0.03 mm within a length range of 500 mm.

[0012] Furthermore, the flatness tolerance of the strip-shaped bonding surface is 0.03 mm.

[0013] Furthermore, the air-avoiding surface and the strip-shaped fitting surface are connected via rounded corners.

[0014] Furthermore, the strip-shaped fitting surface is connected to the outer side of the mold body through a rounded corner.

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] (1) Improve mold assembly efficiency: By performing air-avoidance treatment on the installation contact surface to obtain a strip-shaped fitting surface and an air-avoidance surface, the area requiring fine grinding and repair is reduced, shortening the mold assembly cycle and improving efficiency.

[0017] (2) Ensure the stability and safety of mold assembly: By setting the depth of the avoidance and the accuracy of the avoidance surface, uniform force is guaranteed during installation, and the width of the strip fitting surface is set to balance the pressure and the area that needs fine grinding when the fitting surface is subjected to force, thereby ensuring the stability of the mold.

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0023] In the production process of large-scale parts and components, large deep-cavity molds and vertical wall high mounting fitting surfaces are often used. When performing lateral punching, the mold needs to be finely processed so that the mold fits tightly, the surface is smooth and there are no gaps during installation. However, as the height of the mold increases, the error in the machining of the contact surface of the mold installation becomes larger, and excessive errors will cause interference between the assembled hydraulic side punch module and the mold body during installation, affecting product quality. In order to ensure the fit of the contact surface, the contact surface needs to be manually ground, which is labor-intensive, time-consuming and has unstable quality. The side punch installation structure of the mold in this embodiment obtains a fine strip-shaped fitting surface by setting an air-avoidance groove at the mounting contact surface 3, thereby reducing the area of ​​the fine surface, reducing the time of assembly work while ensuring support, and improving the efficiency of mold installation and splicing.

[0024] The side flushing installation structure of this embodiment is as follows Figure 1 As shown in FIG, it is a partial schematic diagram of the strip-shaped fitting surface. When the side punching mold body 1 and the side punching module 2 are installed and matched, a good overlapping contact surface is required. If the fitting accuracy is not enough, it will affect the side punching and product quality. Figure 2 The side punch installation structure of the mold of this embodiment is shown, which includes a mold body 1, a side punch module 2, a mounting contact surface 3, a strip-shaped fitting surface 11, and a clearance surface 12. The side punch module 2 and the mold body 1 are connected through the mounting contact surface 3. The strip-shaped fitting surface 11 and the clearance surface 12 are provided on the mounting contact surface 3. The strip-shaped fitting surface 11 is provided along the edge of the mounting contact surface 3. The clearance surface 12 is obtained by performing a clearance treatment on the portion of the mounting contact surface 3 other than the strip-shaped fitting surface 11.

[0025] In this embodiment, the clearance depth of the clearance surface 12 is 1 mm.

[0026] In this embodiment, the precision of the air-avoiding surface 12 is 0.05 mm.

[0027] In this embodiment, the width of the strip-shaped laminating surface 11 is uniform.

[0028] In this embodiment, the width of the strip-shaped fitting surface 11 is 20 mm, which is sufficient to ensure that the side punch module 2 is firmly fixed.

[0029] In this embodiment, the precision of the strip-shaped laminating surface 11 is 0.01 mm.

[0030] In this embodiment, the verticality tolerance of the strip-shaped laminating surface 11 relative to the horizontal bottom surface 4 is ±0.03 mm within a length range of 500 mm.

[0031] In this embodiment, the flatness tolerance of the strip-shaped laminating surface 11 is 0.03 mm.

[0032] In this embodiment, the air-avoiding surface 12 is connected to the strip-shaped bonding surface 11 through a rounded corner. The strip-shaped bonding surface 11 is also connected to the outer side of the mold body 1 through a rounded corner.

[0033] The structure in this embodiment will not lose the supporting strength of the module body, and even if there are errors in the fitting surface during assembly, the installation work can be quickly achieved only by matching the strip fitting surface 11. By limiting the width, precision, flatness and verticality of the strip fitting surface 11, the close fit between the mold body 1 and the side punching module 2 is guaranteed. In addition, since there is relative movement between the side punching module and the punching knife during side punching, the guarantee of verticality and precision can also reduce resistance, extend the maintenance cycle of the mold and the service life of the punching knife. The air-avoiding surface 12 and the strip fitting surface 11, as well as the strip fitting surface 11 and the mold body 1 are connected by rounded corners, which reduces collisions and scratches during installation. This embodiment reduces the mold assembly time and improves efficiency while ensuring the stability and uniform force of the mold and reducing unnecessary extrusion. In addition, the strip fitting surface 11 is set according to the shape to ensure a smooth surface and easy fixation. The air-avoiding surface 12 can reduce the weight of the part while avoiding unnecessary processing operations. The structure has low R&D and production costs, is suitable for sharing with multiple product lines, and can be quickly converted, greatly reducing the company's production and storage costs.

[0034] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any person skilled in the art can easily conceive of various equivalent modifications or substitutions within the technical scope disclosed in the present invention, and such modifications or substitutions are intended to be within the scope of protection of the present invention. Therefore, the scope of protection of the present invention shall be subject to the scope of protection of the claims.
