Lost foam casting mould with positioning accuracy for electromotor shell

Abstract

The invention discloses a lost foam casting mould with the positioning accuracy for an electromotor shell. The lost foam casting mould with the positioning accuracy for the electromotor shell comprises a main casting pipe and an electromotor shell body, wherein a casting funnel device is fixedly arranged at the upper end of the main casting pipe; a No.1 branched casting pipe is fixedly arrangedat one end of a horizontal casting pipe; a fixed rod is fixedly arranged at the lower end of a No.2 branched casting pipe; a casting port is arranged under the fixed rod; and a sand residue filter screen is arranged above the casting port. According to the lost foam casting mould with the positioning accuracy for the electromotor shell provided by the invention, through arranging a rubber spacer,a positioning main rod and the sand residue filter screen, the frictional resistance between the equipment and the ground can be increased, so that the overall stability of the equipment is improved,and a buffer effect can be further achieved; and the accuracy of a product casting position can be effectively improved through the positioning main rod, and dry sand impurities in molten steel can be effectively cleaned and filtered through the sand residue filter screen, so that the lost foam casting mould with the positioning accuracy for the electromotor shell brings a better use prospect.

Description

technical field [0001] The invention relates to the field of mold manufacturing, in particular to a lost foam mold with accurate positioning for a motor casing. Background technique [0002] Lost foam is one of the most advanced casting techniques in the world at present. It is known as a revolution in the history of casting, and it is called green casting in the 21st century at home and abroad. Lost foam, also known as solid mold casting, is a solid mold casting in which foam plastic molds use binder-free dry sand combined with vacuum pumping technology. It is to bond and combine foam models similar in size and shape to castings to form model clusters, brush refractory coatings and dry them. Finally, it is buried in dry quartz sand for vibration molding, pouring under negative pressure to vaporize the model, liquid metal occupies the position of the model, and solidifies and cools to form a new casting method. In recent years, lost foam casting has developed rapidly in Chi...

Problems solved by technology

[0003] The existing lost foam molds have certain disadvantages in use. First, the equipment is prone to slipping when it is in contact with the ground, which is not convenient for people to use. Secondly, the lost foam cannot be positioned accurately and quickly. Good removal of impurities in dry sand can not control the flow rate of molten steel well, which has a certain impact in actual operation. For this reason, we propose a lost foam mold with accurate positioning for the motor shell
