Description

Technical Field

[0001] The present application relates to the technical field of mold frames, and more specifically, to a metal mold frame. Background Art

[0002] The metal mold frame is also the support frame of the mold, which can also be called a steel mold plate. It is an industrial equipment used to cast solid castings of various shapes. Most metal mold frames are composed of an upper mold frame, a lower mold frame, a mold base, a mold groove, connecting parts and other structures. By merging the upper and lower molds, the injection molding system is used to inject the injection molding material into the mold groove. The product can be formed by cooling, and then it can effectively carry and fix the casting mold to ensure the smooth progress of the pouring process. Therefore, the metal mold frame plays a great role in the industrial industry.

[0003] However, most of the existing metal molds on the market require manual demoulding, and when the mold groove is deep, demoulding will be more troublesome, which will bring certain difficulties to the workers in demoulding work, resulting in time-consuming and labor-intensive work, and reducing the overall work efficiency.
