[CN 201721890598.1] Mechanical balancing device for gas pressure in holding furnace of differential pressure casting machine
[CN 201721890598.1] A mechanical balancing device for gas pressure in the holding furnace of a differential pressure casting machine Title: A mechanical balancing device for gas pressure in the holding furnace of a differential pressure casting machine Application number: CN 201721890598.1 Applicant: Qiqihar Second Machine Tool (Group) Co., Ltd. Application date: 2017-12-28 Patent type: Utility model This utility model relates to a mechanical balancing device for gas pressure in the holding furnace of a differential pressure casting machine. It mainly solves the problems of time-consuming and laborious lifting and high-temperature operation danger when the existing differential pressure casting machine is filled with molten metal. It is characterized in that: the bottom of the moving plate (2) is fixed with a linkage oil cylinder (9), and the left and right ends of the moving plate (2) are respectively fixed with a left base (3) and a right base (13), wherein the left base (3) is built There is a left bolt (5), and the right end of the left bolt (5) is connected with the linkage oil cylinder, the left end of the left bolt (5) is connected to the left wedge (4), the right base (13) is internally provided with a right bolt (10), the left end of the right bolt (10) is connected to the piston rod of the linkage oil cylinder, and the right end of the right bolt (10) is connected to the right wedge (12). The differential pressure casting machine holding furnace gas pressure mechanical balance device can realize the holding furnace automatically moved in and out, easy to operate, safe and reliable.
