Abstract

The invention relates to a pneumatic manipulator which mainly solves the problems of low wax mold finished product ratio, low working efficiency and relatively large potential safety hazard of manual mold taking during investment casting. The pneumatic manipulator is characterized in that a piston rod of a lifting cylinder (3) is tubular; two clamps (1) are hinged to the lower end of the piston rod of the lifting cylinder (3); the upper ends of the two clamps (1) are respectively hinged with two connection rods (4); the upper ends of the two connection rods (4) are hinged with the lower end of a piston rod of a clamp cylinder (2); the piston rod of the clamp cylinder (2) is located in the piston rod of the lifting cylinder (3), and runs through the piston rod of the lifting cylinder (3); the clamp cylinder (2) comprises a membrane (5); and the piston rod, which is located below the membrane (5), of the clamp cylinder (2) is sleeved with reset springs (6). According to the pneumatic manipulator, by the ingenious combination of the clamp cylinder and the lifting cylinder, automatic mold taking can be realized; and during wax mold taking, the force is balanced; the wax mold finished product ratio is high, the mold taking efficiency is high, and the potential safety hazard is avoided.

Description

technical field

[0001] The invention relates to an automatic mold taking device for investment casting, in particular to a pneumatic manipulator. Background technique

[0002] Investment casting is also known as lost wax casting or lost wax casting. The production process of investment casting is mainly divided into wax pressing, wax repair, tree formation, shell making, shell baking, pouring, shelling, post-processing, inspection, etc., processing Metal parts are generally copied in batches with fusible materials (such as wax, plastic, etc.). Multi-layer refractory material is coated on the permanent mold, and the refractory material coating is dried and hardened to form a mold shell. If a wax mold is used, steam or hot water is used to melt the wax mold from the mold shell, and then the fusible material in the mold shell is melted. outflow. After the mold shell is roasted to make it strong, the molten liquid metal is poured into the mold shell, and the liquid metal is co...
