Abstract

The invention belongs to the technical field of lost foam casting dies and provides an automatic core pulling mechanism for a single cylinder engine inner cavity loose piece. The provided automatic core pulling mechanism for the single cylinder engine inner cavity loose piece is a part of a single cylinder engine lost foam casting die and comprises an upper die, a lower die and a die release plate. The automatic core pulling mechanism is provided with outer side steam cylinders. The outer side steam cylinders are arranged on the two sides of the single cylinder engine lost foam casting die vertically. Piston rods at the top ends of the outer side steam cylinders are fixedly connected with the die release plate. The lower end of a lower die insert penetrates through the die release plate tobe fixed to the lower die. The side face of the part, protruding from the die release plate, of the lower die insert is provided with an inclined sliding groove. The inclined sliding groove is matched with a lug fixed to the die release plate. The lug is fixedly connected with the loose piece for forming a single cylinder engine inner cavity. Through the automatic core pulling mechanism, automatic core pulling of the single cylinder engine inner cavity loose piece is achieved, and full-automatic unmanned operation continuous production of a single cylinder engine product white area in the field of lost foam casting dies is achieved.

Description

technical field [0001] The invention belongs to the technical field of lost foam moulds, and mainly proposes an automatic core-pulling mechanism for a movable block in a single-cylinder machine cavity. Background technique [0002] Core pulling is mainly aimed at the molding area where there is an undercut in the inner cavity of the single-cylinder machine product (inconsistent with the upper and lower mold opening directions, requiring lateral movement). A single-cylinder machine product may have one or more shape undercuts according to the needs of different product functions. [0003] The inner cavity of the existing single-cylinder lost foam mold adopts a manual core-pulling structure, the labor intensity of the workers is high, and the working conditions are harsh (high temperature operation). Machine lost foam molds must all adopt automatic core pulling. Contents of the invention [0004] In order to solve the above-mentioned technical problems, the purpose of the ...
