What are the elements of motion "interference" between the various mechanisms of the mold?

"Interference" request analysis method: According to various forms of motion "interference" elements on the injection molded parts, an analysis method for the mold structure scheme that collides between moving components is worked out. When the injection mold is working, the opening and closing motion of the mold is the main motion, and the core pulling motion of the injection mold is derived, as well as the independent movement of the injection molded part produced by the ejector pin of the injection molding machine. The movement of various forms of movement "interference" may occur.
(1) When the movement between the mold mechanisms "interferes" with the injection mold, the mutual collision between the components of the various moving mechanisms of the mold is called motion "interference".
(2) Types of motion "interference" of mold mechanism There are three types of motion "interference". The mold mechanism includes "obstacle body" type, core-pulling type and core-pulling demoulding.
①The movement of the "obstacle body" type "interferences" the injection mold. Due to the existence of the "obstacle body" on the shape of the injection molded part, the phenomenon of magnetic collision between the "obstacle body" and the various moving mechanisms of the mold is called "obstacle body". body" type of motion "interference".
② The core-pulling type of movement "interferes" with the core-pulling movement of various types of holes or grooves in the injection mold. If the axes of these types of holes or grooves intersect or stagger, it will cause the components of the core-pulling mechanism They collide with each other, and this collision phenomenon is called core-pulling type of motion "interference".
③ The movement "interference" of the core-pulling and demolding type collides with each other between the components of the injection mold core-pulling mechanism and the demolding mechanism, which is called the movement "interference" of the core-pulling and demolding type.
