Technical Field

[0001] The utility model relates to the field of positioning and clamping devices, in particular to a positioning and clamping device for injection mold production. Background Art

[0002] The positioning and clamping device for injection mold production can ensure the accurate positioning and stable clamping of the mold during the injection molding process, thereby improving production efficiency and product quality. An injection mold is a tool used for plastic injection molding, also known as an injection mold or injection mold. It is one of the most commonly used mold types in injection molding processing, and is mainly used to produce various plastic products. The working principle of an injection mold is to inject heated and molten plastic particles into the mold cavity through a plastic injection molding machine. After cooling and solidification, the mold can be opened to take out the molded plastic product.

[0003] However, the traditional positioning and clamping device for injection mold production cannot conveniently clamp and fix the mold at the center of the device, which requires users to spend time adjusting the position of the mold to improve the accuracy of the mold during injection molding. This makes the positioning and clamping device less convenient to use and less accurate.

[0004] Therefore, those skilled in the art provide a positioning and clamping device for injection mold production to solve the problems raised in the above background technology. Utility Model Content
