Technical Field
[0001] The utility model relates to the field of injection mold grinding equipment, in particular to an injection mold cavity grinding device. Background Art
[0002] The injection mold cavity is the part that constitutes the product space, that is, the part of the mold that forms the outer surface of the plastic part. In an injection mold, the cavity corresponds to the core, and they jointly constitute the molding space of the mold. The quality of the cavity directly affects the part quality and the mold life. Therefore, the quality processing of the cavity is particularly important. In the process of processing the cavity, a device specifically used for grinding the injection mold cavity is often used, generally called the grinding device for the injection mold cavity, which can effectively improve the product quality, ensure the production efficiency and extend the mold life.
[0003] When the existing grinding devices perform the same grinding operations on multiple cavities, they often involve complex clamping and adjustment operations, which are not only inefficient but also difficult to ensure the accuracy and consistency of grinding, thus affecting the grinding accuracy. Therefore, a device that can adjust the position of the grinding head while keeping the clamping position of the cavity mold unchanged to achieve the same grinding of multiple cavities is developed. For this reason, we propose an injection mold cavity grinding device. Summary of the Utility Model
