Simple-to-assemble iron casting mould

Abstract

The invention belongs to the field of moulds and particularly relates to a simple-to-assemble iron casting mould. On account of the problems that the existing water pipe is inconvenient to mount on water pipe joints and the discharging of air in machined grooves is un-thorough, the following technical scheme is provided. The iron casting mould comprises an upper mould and a lower mould, wherein anupper machined groove is formed in the lower end side wall of the upper mould, a lower machined groove matched with the upper machined groove is formed in the upper end side wall of the lower mould,an upper through hole matched with the upper machined groove is formed in the side wall of the upper mould, a lower through hole matched with the lower machined groove is formed in the side wall of the lower mould, and water pipe joints matched with the upper through hole and the lower through hole are separately formed in the two side walls of the upper mould and the lower mould. Two clamping blocks are driven to move towards each other or far away from each other through the cooperation of threaded rods, moving plates, swing rods and the like, and accordingly, the water pipe can be rapidly installed and disassembled, so that the cost is saved. Besides, by utilizing the structure including air holes, connecting grooves and the like, the air in the machined grooves is more thoroughly discharged, and the design is convenient and practical.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an iron casting mold which is easy to assemble. Background technique [0002] Iron castings are things cast with molten iron, mainly some accessories, for example, jewelry swords, bells, tripods, terracotta warriors, etc., including appearance quality, inner quality and use quality. Appearance quality refers to the surface roughness, surface defects, size deviation, shape deviation, and weight deviation of castings; mainly refers to the metallographic structure of castings and the holes, cracks, inclusions, segregation, etc. Working durability under different conditions, including wear resistance, corrosion resistance, shock resistance, fatigue, shock absorption, etc., as well as process properties such as machinability, weldability, etc. Due to various factors, air holes often appear in iron castings , pinholes, slag inclusions, cracks, pits and other defects. Commonly used rep...

AI Technical Summary

Problems solved by technology

[0005] The invention proposes an easy-to-assemble cast iron mold, which solves the problem that when the water pipe is connected with the water pipe joint, it is generally inconvenient to disassemble the clamp after use, and some clamps need to be removed after use. The water pipe can only be removed by cutting it off, which increases the economic cost, and it is very inconvenient to disassemble and install the water pipe. In addition, when pouring molten iron, it is carried out through the feed port, so that the gas in the mold cannot be quickly discharged along the feed port. This will lead to the problem of holes and cracks in cast iron parts after forming
