Upper movable mold gravity casting machine with simple structure

Abstract

A gravity casting machine with a simple upper movement mode, characterized in that it includes a frame mechanism, an upper movable mold mechanism, and a control mechanism; the frame mechanism is provided with an upper machine plate, a lower template, and machine feet in the gravity casting machine , both sides of the upper machine plate and the lower formwork are provided with side columns and middle columns; the upper movable mold mechanism includes an oil cylinder, a top plate, a support, and an upper formwork on the upper machine plate; the control mechanism is in The frame mechanism is equipped with a control box and a hydraulic system; the upper movable mold mechanism installed on the upper machine plate is used to replace the original lower movable mold mechanism, which effectively reduces the operating surface of the upper mold and facilitates the core worker to place the riser by himself. Reduce safety addiction; adopt the lower ejection device installed under the lower template, which is beneficial for the product to be separated from the lower mold first, which is beneficial to energy saving and further achieves automation; adopting the original gravity casting machine in the lower motion mode for transformation can save investment , Reduce waste and reduce product costs.

Description

technical field [0001] The application relates to the field of casting equipment, in particular to a gravity casting machine with a simple structure and an upward movement mode. Background technique [0002] In the field of casting, it is the most economical and common method to cast aluminum alloy castings with metal molds. However, the original gravity casting machine slides the lower plate up and down to open and close the mold, and the operator on the casting machine places the riser and waits for the following operations. The operator places the sand core, and then the upper operator casts after the mold is closed; or the lower operator climbs up the casting machine to place the pouring riser, then comes down to place the sand core, and let the robot cast, which is not only a waste of manpower, but also labor-intensive and efficient. Low cost, high cost, and great safety addiction. Contents of the invention [0003] In view of the above problems, the present applicat...
