[0002] A mold is a special tool or equipment used to manufacture products. It is usually made of metal, plastic or other materials and has the shape and structure of the desired product. The main function of the mold is to shape or cut the raw materials during the manufacturing process to obtain the desired product shape. It can be used in various manufacturing industries, such as injection molding, die casting, forging, pressing, stamping, etc.

[0003] During the stamping process, the mold needs to be positioned to prevent the upper mold from deflecting when it is pressed down. The Chinese patent provides a mold frame positioning device (CN202222368255.6) for stable mold positioning, including a workbench, the top of which is fixedly connected to the lower mold, the top of which is fixedly connected to evenly distributed guide rods, a top plate is provided on the top of the workbench, the top of the guide rod is fixedly connected to the bottom of the top plate, and an electric push rod is fixedly installed on the top of the top plate. The utility model uses the guide rod to keep the bearing plate and the upper mold moving downward stably, and monitors whether the bearing plate is tilted by the infrared receiver and infrared transmitter set on the movable plate. During the downward movement of the upper mold, the extension rod will first enter the extension seat to play a certain positioning role. The setting of the contact sensor can avoid the upper mold and the lower mold from deflecting and continuing to stamp, thereby improving the stamping quality of the workpiece and avoiding damage to the device caused by misaligned stamping, solving the problem of poor positioning effect of the previous stamping mold.

[0004] The above scheme monitors whether the supporting plate is tilted by means of an infrared receiver and an infrared transmitter arranged on the movable plate. When it is detected that the supporting plate is tilted, the staff is required to repeatedly adjust the mold. The mold processing can only be carried out when the monitoring data is adjusted to a normal state, resulting in the device failing to achieve a good positioning effect. Therefore, a mold frame positioning device for stable mold positioning is provided to solve the above problem. Utility Model Content
