Lost-foam-casting bimetal hammerhead pouring system

Abstract

The invention discloses a lost-foam-casting bimetal hammerhead pouring system, and relates to a pouring system.The lost-foam-casting bimetal hammerhead pouring system comprises a first pouring system body for pouring of a material of a hammer handle part and a second pouring system body for pouring of a material of a hammerhead part.The first pouring system body comprises a first pouring cup, a first vertical pouring channel, a first transverse pouring channel and a hammer handle cavity; the second pouring system body comprises a second pouring cup, a second vertical pouring channel, a second upper transverse pouring channel, a second lower transverse pouring channel, a hammer head cavity and a feeding head.According to the second pouring system body, the double-pouring-opening structure and the high-position feeding head structure are adopted, high-hardness-material liquid metal enters the hammer head cavity from the second lower transverse pouring channel firstly along the second vertical pouring channel, and then enters the feeding head from the second upper transverse pouring channel; as the newly-entering liquid metal is high in temperature, the temperature of the feeding head can be effectively increased, the feeding effect can be greatly improved accordingly, and the casting defects can be avoided.The product further has the advantages of being high in impact-resistant strength, excellent in appearance quality, stable in performance, long in service life and the like, and the customer satisfaction degree can be greatly increased.

Description

technical field [0001] The invention relates to a gating system, in particular to a gating system for bimetallic hammerheads in lost foam casting. Background technique [0002] The shape of the bimetallic hammer head is as follows: Figure 1-Figure 2 As shown, it is a commonly used wearing part in crushing equipment. The hammer handle needs to be made of strong and tough material that can resist impact. Accurate control can make the product have stable performance. The existing bimetallic hammer gating system for lost foam casting generally has the following disadvantages: [0003] 1. The product is prone to casting defects, and the impact strength of its joint parts is small, posing safety hazards. [0004] 2. The pouring system is easy to stick sand, and the appearance quality of the product is low. [0005] 3. It is difficult to quantify the metal by pouring first, and the product performance is unstable. Contents of the invention [0006] The technical problem to b...
