Description

Technical Field

[0001] The utility model belongs to the technical field of inserts, and in particular relates to a T-shaped insert structure. Background Art

[0002] Inserts in molds specifically refer to irregular mold accessories used to be embedded in molds, which play the role of fixing the template and filling the space between the templates. The main functions of inserts in injection molds are as follows: first, saving injection mold manufacturing materials; second, facilitating mold modification; third, facilitating injection mold exhaust; fourth, facilitating injection mold processing; and fifth, extending the service life of injection molds. Many mold structures have tight space. When making inserts, because the inserts have a small penetration surface, copper plugging through holes is generally used after the screws are fixed to solve the problem of less penetration surface. However, the use of copper plugging through holes will make it difficult to remove the inserts later. When the inserts need to be removed, the copper in the through holes needs to be pried off. After the through holes are exposed, the screws inside can be unfastened and the inserts can be removed from the mold. At present, there is a lack of a reliable and durable T-shaped insert structure that can facilitate the removal of the inserts from the mold and solve the problem of less penetration surface of the inserts.

[0003] Therefore, a new technology is needed to solve the problem of lacking a reliable and durable T-shaped insert structure in the prior art. Utility Model Content

[0004] In order to solve the above problems in the prior art, the utility model provides a T-shaped insert structure, which is reliable and durable, can facilitate the removal of the insert from the mold, and can solve the problem of less penetration surface of the insert.

[0005] The utility model adopts the following technical solutions:

[0006] A T-shaped insert structure comprises an insert and a screw; the side of the insert is provided with a first groove for facilitating the installation and removal of the screw; the end face of the insert is provided with a through hole; the through hole is connected to the first groove; when the screw is installed, when viewed from the front, the size of the through hole is smaller than the outer contour of the screw nut, and the size of the through hole is at least large enough for a wrench to enter and tighten the screw.

[0007] Furthermore, the first groove is a “T”-shaped through groove.

[0008] Furthermore, the through hole is a circular through hole.

[0009] Furthermore, the penetration surface of the inlay is larger than the penetration surface of the conventional inlay.

[0010] Furthermore, the outer contour of the screw nut is circular.

[0011] Furthermore, the screw nut is provided with a screwing groove; the screwing groove is used to provide a matching position for a wrench to screw the screw.

[0012] Furthermore, the twisting groove is an inner hexagonal groove.

[0013] Furthermore, the through hole is arranged at the center of the inlay.

[0014] Furthermore, the inlay can be installed at a corresponding position of the mold through the screws.

[0015] Furthermore, the screw can be threadably connected to the mold.

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] A T-shaped insert structure of the utility model comprises an insert and a screw, wherein the side of the insert is provided with a first groove, and the first groove can facilitate the installation and removal of the screw. The utility model changes the installation mode of the previous screw, and solves the problem that the through hole needs to be blocked with copper after the screw is installed from the through hole, so that it is inconvenient to remove the insert from the mold; in one embodiment, the first groove can be expressed as a "T"-shaped through groove, and the screw can be easily installed in the first groove, and then the wrench can lock the screw into the mold through the through hole; when disassembling, the wrench can easily enter from the through hole to release the screw, and the insert can be conveniently removed from the mold; after the through hole of the utility model is designed, it is smaller than the through hole of the previous insert, and the area of ​​the insert penetration surface is increased. At the same time, the through hole of the utility model can allow the wrench to pass through and twist the screw, which can facilitate the installation and removal of the screw, that is, it is convenient for the T-shaped insert structure of the utility model to be installed on the mold, and it is also convenient for the T-shaped insert structure of the utility model to be removed from the mold, thereby improving the ability and efficiency of mold modification in production.
