Hierarchical opening and closing mode low pressure casting machine

Abstract

The invention belongs to casting equipment in the machinery manufacturing industry, in particular to a low-pressure die-casting machine with multi-level opening-closing molds. Primary opening-closing mold supporting seats (2) of the same structures are symmetrically mounted on the left and right sides on a workbench (1) fixedly; secondary opening-closing mold supporting seats (3) are symmetrically connected onto the primary opening-closing mold supporting seats (2) through connecting blocks (8); secondary opening-closing molds of the same structures as primary opening-closing molds are mounted in the secondary opening-closing mold supporting seats (3); a lateral opening-closing mold supporting seat (6) is fixedly mounted on the back surface in the middle of the workbench (1) and perpendicular to the left and right ends of the workbench (1). According to the low-pressure die-casting machine, drawing deflection of castings can be avoided, and molds are opened and closed in levels according to different structures of the castings, so that limit of casting shrinkage during a cooling process can be reduced, and the castings are prevented from fracturing. The low-pressure die-casting machine is compact in structure, convenient and flexible to operate, and high in production efficiency.

Description

technical field [0001] The invention belongs to casting equipment in the machinery manufacturing industry, in particular to a low-pressure casting machine with hierarchical opening and closing modes. Background technique [0002] At present, the production of non-ferrous metal castings by low-pressure casting technology mainly uses vertical and horizontal low-pressure casting machines. The advantages of vertical low-pressure casting machines are that they can be centrally positioned and convenient for ejection. inconvenient. It is convenient to install molds and take out castings during the production of castings by horizontal low-pressure casting machines. However, due to various reasons such as the structure of the parts, the design and processing of molds, and the use of paint, the left and right mold opening forces are uneven, so the mold opening During the process, the casting is pulled to cause deformation of the casting, and the shrinkage of the large casting is rela...

[0002] At present, the production of non-ferrous metal castings by low-pressure casting technology mainly uses vertical and horizontal low-pressure casting machines. The advantages of vertical low-pressure casting machines are that they can be centrally positioned and convenient for ejection. inconvenient

It is convenient to install molds and take out castings during the production of castings by horizontal low-pressure casting machines. However, due to various reasons such as the structure of the parts, the design and processing of molds, and the use of paint, the left and right mold opening forces are uneven, so the mold opening During the process, the casting is pulled and deformed, and the shrinkage of the large casting is large during the cooling process, causing the casting to break
