Description

Technical Field

[0001] This utility model relates to the field of stamping die technology, and in particular to an automotive die that is easy to adjust and quick-release. Background Technology

[0002] Lightweighting is the mainstream trend in automotive parts. Aluminum parts are widely used in body parts. Since aluminum parts are basically riveted, the precision requirements of parts are getting higher and higher. The interchangeability of the mold structure itself is also becoming more and more important. In order to improve the competitive advantage, the mold structure needs to be simplified. Therefore, it is urgent to innovate the original mold structure.

[0003] Currently, in order to resolve the issue of producing engine hood hinge reinforcement plate parts for the L946 project, see [reference needed]. Figure 1 As shown, the part has a rivet screw boss around the rivet screw hole. By controlling the height and shape of the boss, the torque can be adjusted. In traditional mold structure design, the boss is usually integrally formed with the mold, making adjustments and changes difficult and requiring frequent mold disassembly for verification, resulting in low verification and maintenance efficiency. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide an easy-to-adjust and quick-release automotive mold to solve the problems of one-piece mold molding, difficulty in adjustment and modification, and low efficiency in verification and maintenance.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] This utility model discloses an easily adjustable and quick-release automotive mold, comprising:

[0007] Templates with lifting lugs fixed to both sides;

[0008] Guide plates are symmetrically fixed to both ends of the upper surface of the template, and a forming block is fixed to the riveting area in the middle of the template.

[0009] The molding block has a quick-release hole at the position of the part boss. The quick-release hole passes through the template and the molding block in sequence, and a quick-release structure can be detachably installed in the quick-release hole for protruding from the upper surface of the molding block and contacting the part.

[0010] Furthermore, the quick-release structure includes a connector and a quick-release rod that can be inserted into the quick-release hole;

[0011] One end of the quick-release lever has a pressure head for contacting the part, and the other end of the quick-release lever has a connecting part for connecting to the connector.

[0012] Furthermore, the connector is a nut, and the connector is threadedly connected to the connecting part of the quick-release rod.

[0013] Furthermore, two forming blocks are symmetrically fixed within the riveting area of ​​the template, and each forming block has two quick-release holes.

[0014] Furthermore, the quick-release hole is a countersunk hole structure.

[0015] Furthermore, the template has a plate-like structure, and U-shaped mounting holes are provided at both ends of the template.

[0016] In the above technical solution, the automotive mold provided by this utility model, which is easy to adjust and quick-release, has the following advantages:

[0017] Compared with the prior art, the mold designed in this utility model has quick-release holes that pass through the template and the forming block in sequence at the corresponding part boss position. A quick-release structure can be detachably installed in the quick-release hole. The quick-release rod of the quick-release structure protrudes from the upper surface of the forming block and contacts the part. The quick-release rod of the quick-release structure can be detached separately for independent processing and adjustment. Torque adjustment does not require frequent machine operation, which effectively reduces the mold debugging cost and improves the verification and maintenance efficiency. Attached Figure Description

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] See Figure 1 As shown;

[0027] A utility model provides an easy-to-adjust and quick-release automotive mold, comprising: a template 10;

[0028] Template 10 has a plate-like structure. U-shaped mounting holes are provided at both ends of template 10. Lifting lugs 11 are fixed to both sides of template 10. Guide plates 12 for guiding are symmetrically fixed to both ends of the upper surface of template 10. Mold limiting posts 13 are symmetrically fixed to both sides of guide plates 12. A forming block 14 is fixed to the riveting area in the middle of template 10.

[0029] The molding block 14 has a quick-release hole 15 at the position of the part boss. The quick-release hole 15 passes through the template 10 and the molding block 14 in sequence, and the quick-release structure 20 can be detachably installed in the quick-release hole 15 for protruding from the upper surface of the molding block 14 and contacting the part.

[0030] The quick-release structure 20 includes a quick-release rod 21 and a connector 22. The quick-release rod 21 can be inserted into the quick-release hole 15. One end of the quick-release rod 21 has a pressure head and the other end has a connecting part. The pressure head acts on the part to press the rivet screw forming position. The connecting part connects with the connector 22 to press and lock the quick-release rod 21 onto the forming block 14. The connector 22 is a nut in the prior art. The connector 22 is threadedly connected to the connecting part of the quick-release rod 21.

[0031] Preferably, two forming blocks 14 are symmetrically fixed in the riveting area of ​​the template 10. Each forming block 14 has two quick-release holes 15. That is to say, the mold is a two-cavity structure, that is, four adjustable quick-release structures 20 are installed in one mold, which is convenient to use.

[0032] Preferably, the quick-release hole 15 is a countersunk hole structure. The quick-release hole 15 includes a first hole section and a second hole section from top to bottom. The diameter of the second hole section is larger than that of the first hole section. The first hole section is used to install the quick-release rod 21, and the second hole section is used to accommodate the connector 22, which makes disassembly convenient.

[0033] In the above technical solution, the automobile mold that is easy to adjust and quick-release provided by this utility model effectively shortens the mold assembly cycle by detachably installing independent adjustment quick-release structures 20 on the fixed forming block 14. The mold is a two-cavity structure, that is, four adjustment quick-release structures 20 are set in one mold. The quick-release structure 20 uses the quick-release rod 21 to press the head of the part to press the rivet screw forming position, and the bottom is locked by the nut. During the mold stamping operation, the height of the boss and the forming block 14 can be adjusted independently. Moreover, it can be directly disassembled from the back of the mold. In addition, it also avoids the use of the mold pressure for overall rough adjustment, effectively reducing the phenomenon of ambiguity in the torque magnitude in the conventional way.

[0034] This mold has the following advantages compared to existing technologies:

[0035] 1) The quick-release structure allows for independent disassembly and installation, making operation simple. The torque of the rivet screw can be controlled by adjusting the height of the quick-release rod.

[0036] 2) Effectively reduces the tedious debugging and verification process;

[0037] 3) Low implementation cost and low initial investment;

[0038] 4) The mold is easy to maintain and has a longer service life.

[0039] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
