Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of mold frames, in particular to a mold frame mechanism for a mold. BACKGROUND

[0002] A mold frame is a support for a mold, such as a die-casting machine that combines and fixes the parts of a mold in a certain pattern and position, and enables the mold to be installed on the die-casting machine for work. The mold frame is composed of a push-out mechanism, a guide mechanism, a pre-reset mechanism, a mold foot pad, and a seat plate. The application of the mold currently involves every product (such as automobiles, aerospace, daily necessities, electrical communication, medical products, and equipment), and molds are used for the production of products in large quantities. The mold frame is an integral part of the mold. The precision requirements of the mold frame are determined according to different levels and product needs. The mold frame is a semi-finished product of the mold, composed of various steel plates and parts, and can be said to be the skeleton of the entire mold.
