[0002] Moulds play a very important role in the machinery industry. Existing moulds are generally provided with an upper mould and a lower mould that match each other, that is, the mould is composed of an upper mould and a lower mould. When the upper mould and the lower mould are closed, they are prone to misalignment. Positioning devices need to be provided on the upper mould and the lower mould to ensure accurate positioning when the upper and lower moulds are closed.
[0003] There are many existing mold positioning devices, which generally use guide columns and guide holes for guiding mold closing. After being used for a period of time, the guide columns are prone to surface wear, which causes the upper mold and the lower mold to be closed together regardless of whether they are deviated or not during mold closing. Even if the mold is deviated, it will be closed together, which may cause quality problems in subsequent products. In addition, during the processing, it is inconvenient to remove the processed workpiece from the mold, resulting in reduced work efficiency.
[0004] Therefore, in view of this, the existing structural deficiencies are studied and improved, and a mold with precise positioning is proposed. Utility Model Content

[0009] Furthermore, a bracket is fixedly installed on the side of the lower mold adjacent to the bearing seat, and the bracket is in a "U"-shaped structure with an opening facing inward.
[0010] Furthermore, a motor is fixedly mounted on the top of the end of the bracket, and a screw rod is fixedly connected to the output end of the motor, and the end of the screw rod is rotatably matched with the bearing seat.
[0011] Furthermore, an upper die is arranged in the middle of the screw rod, and a threaded hole cooperating with the screw rod thread is opened at a diagonal position on one side of the upper die.

In addition, by arranging contacts and travel switches cooperating therewith at the corresponding positions of the upper mold and the lower mold, accurate positioning is ensured when the upper mold and the lower mold are closed, avoiding the influence of product quality due to the deviation of the mold closing position.
[0016] 2. The utility model provides an ejector assembly. After the upper mold and the lower mold are molded, the product is shaped in the mold cavity in the middle of the lower mold.
