Technical Field
[0001] The utility model relates to the technical field of plastic molds, in particular to a mold with a positioning function. Background Art
[0002] A plastic mold is a tool with a specific structure and design that allows plastic raw materials to be formed into a plastic product with a specific shape and size within a mold cavity under conditions such as heating and pressurization. The basic principle is to utilize the plastic's plasticity to inject plastic particles or plastic melt into a mold cavity with a specific shape. After cooling and solidification or other molding processes, the plastic product is obtained with the same shape as the mold cavity.
[0003] However, when existing molds are used to produce plastic parts, if the plastic parts are provided with embedded iron hardware, the embedded iron hardware needs to be ejected after production is completed, making it difficult to fix them. This can easily lead to inaccurate positioning, thus affecting the production quality of the molded plastic parts. Utility Model Content
[0004] The purpose of the present utility model is to provide a mold with a positioning function, which can enable the embedded hardware that is difficult to position on the plastic parts to be adsorbed and positioned when producing plastic parts, thereby avoiding the embedded hardware affecting the quality of the plastic parts due to inaccurate positioning, and solving the problems raised by the above technical background.

[0010] Preferably, two auxiliary cavities B are provided at the top of the lower mold, and the two auxiliary cavities B are connected to the main cavity, and hardware B is inserted into the auxiliary cavities B.
[0011] Compared with the prior art, the beneficial effects of the present invention are as follows:
[0012] The utility model provides a receiving groove and a magnet, which can absorb and position the embedded hardware A that cannot be fixed, thereby limiting the position of the hardware A. The utility model can absorb and position the embedded hardware on the plastic part during the production of the plastic part, thereby preventing the embedded hardware from affecting the quality of the plastic part due to inaccurate positioning.
