Description

Technical Field

[0001] The utility model relates to the technical field of mold inserts, in particular to a diffusion welding smooth fast color-changing insert. Background Art

[0002] Diffusion welding refers to a solid-state welding method that pressurizes the workpiece at high temperature without causing visible deformation and relative movement. Diffusion welding is particularly suitable for joining dissimilar metal materials, heat-resistant alloys and ceramics, intermetallic compounds, composite materials and other new materials, especially for materials that are difficult to weld by fusion welding;

[0003] Insert is a general term. In the mold, it specifically refers to irregular mold accessories that are embedded in the mold to fix the template and fill the space between the templates. Inserts play an important role in mold manufacturing. They can not only save injection mold manufacturing materials, facilitate mold modification, facilitate injection mold venting, facilitate injection mold processing, but also extend the service life of injection molds. There are many types of inserts, including insert pins, insert blocks, insert columns, insert rings, etc. Their materials can be SKD61, SKH51, ASP23, SKD11, etc., or the same as the mold core material. The hardness requirement is above 50HRC, and the standard accuracy is ±0.01mm, depending on the specific mold accuracy requirements;

[0004] During the mold manufacturing process, mold inserts can be used as positioning and fixing parts for mold processing to ensure the shape and accuracy of the mold. At the same time, surface finishing of mold inserts can also improve the accuracy of the mold and reduce processing errors;

[0005] The core of the die-casting mold is the most prone to problems during the production process. To solve this problem, the core part of the mold that is prone to problems is changed into a separate core accessory that can be detached and replaced, called a core pin, or a mold insert pin. It is used to make holes or special shapes on the die-casting during the casting process. It is an accessory on the mold. If there is a problem with the core part during the use of the mold, you only need to disassemble the mold and replace the problematic core pin, without scrapping the entire mold, thus saving costs.

[0006] When replacing conventional inlay pins, the mounting base needs to be removed from the entire mold, and then further structural disassembly and assembly are performed. The entire operation process is relatively time-consuming and labor-intensive.

[0007] Therefore, in view of this, the existing structure and defects are studied and improved, and a diffusion welding smooth fast color changing insert is proposed. Utility Model Content

A connecting screw hole is opened in the center of the inner part of the stabilizing pile, and a connecting groove is opened on the outer lower end surface of the stabilizing pile, and a docking screw hole is opened horizontally below the connecting groove.

[0011] Furthermore, the surface structure of the movable groove matches the surface structure of the connecting groove, and the connecting groove is used to stabilize the pile to translate along the surface of the movable groove inside the device seat, and the aperture of the docking screw hole is the same as the aperture of the fixing screw hole.

[0012] Furthermore, the limit seat includes a limit block, a sliding groove, a connecting screw hole and a docking groove. The left and right side surfaces of the limit block are provided with sliding grooves, and connecting screw holes are provided on both sides of the lower end of the limit block, and a docking groove is provided on the side of the limit block close to the docking seat.

[0013] Furthermore, the surface structure of the docking groove matches the surface structure of the connecting groove, the aperture of the connecting screw hole is the same as the aperture of the fixing screw hole, and the surface structure of the sliding groove matches the surface structure of the moving groove.

[0014] Furthermore, the needle inserting group includes a supporting pile, a needle inserting body and a connecting screw.

[0017] The utility model provides a diffusion welding smooth fast color change insert, which has the following beneficial effects:

[0018] 1. The utility model utilizes the connecting groove opened on the outer side of the stabilizing pile so that the entire connecting seat can be adjusted in horizontal translation along the surface of the movable groove on the inner wall of the base, so that the connecting seat drives the pin set on its top to slide and disassemble from the inside of the device seat. At the same time, the limit block can translate along the surface of the movable groove on the inner wall of the base through the sliding grooves on the two side surfaces, so that the side with the connecting groove fits the side surface of the connecting seat. The connecting seat and the pin set can be clamped and fixed together with the device seat to ensure the overall structural stability of the pin set, and a certain degree of structural protection can be provided for the connecting seat when passing through. In addition, since the connecting screw hole runs through the inner center of the entire stabilizing pile and is interconnected with the base, this structural setting can provide a certain degree of heat conduction and ventilation structural space for the pin set installed in the connecting seat, thereby preventing the entire pin set from being unnecessary affected by long-term use and high temperature factors.

[0019] 2. The utility model, through the fixing screw hole opened in the middle of the base, the docking screw holes opened symmetrically at the lower end of the stabilizing pile, and the connecting screw holes opened on the left and right sides of the limit block, only needs to use screws of matching sizes to connect and fix various structures together, so as to ensure that the entire device can maintain sufficient structural stability in the mold, and at the same time, cooperate with the connecting screw at the lower end of the supporting pile so that the pin body at the top can be screwed by threading to achieve rapid docking or disassembly between the pin group and the connecting seat, so as to facilitate maintenance and replacement of the structure, and the connecting seat itself also provides a structural function of heat conduction for the pin group, and cooperates with the device seat to play a structural function of heat conduction and dissipation.
