Riser wax mold and wax mold manufacturing device

Abstract

The invention relates to the technical field of mold formation, in particular to a riser wax mold and a wax mold manufacturing device. The wax mold manufacturing device comprises a wax ejecting machine, and the riser wax mold mounted in the wax ejecting machine; the riser wax mold comprises a first mold body and a second mold body; the first mold body and the second mold body are closed to form awax mold molding cavity; the wax mold molding cavity is provided with a first cavity wall corresponding to the upper end surface of the riser wax mold, and a second cavity wall corresponding to the lower end surface of the riser wax mold; and the area of the second cavity wall is larger than the area of the first cavity wall, so that the riser wax mold manufactured by the riser wax mold is small in top and large in bottom. The riser wax mold further comprises a pouring gate for injecting wax in the wax mold molding cavity. The wax mold manufacturing device can manufacture the riser wax mold with small top and large bottom to solve the problem of easy breakage falling of the riser wax mold from the pouring gate in the prior art.

Description

technical field [0001] The invention relates to the technical field of mold forming, in particular to a riser wax mold and a wax mold manufacturing device. Background technique [0002] Investment casting, also known as lost foam casting, is a commonly used casting method in the casting field. Its specific process is as follows: firstly, use wax material to make a wax mold of the part to be cast, and then apply mud on the wax mold to form a mud mold. After the mold is dried, put it into hot water to melt and discharge the wax mold inside, then take out the clay mold that has melted the wax mold and bake it into a pottery mold, and finally pour metal solution into the pottery mold, and break it after the metal solution cools down Pottery molds can get the required parts. [0003] When using the investment casting method to cast parts, usually the sprue cup wax mold, riser wax mold, sprue wax mold, casting wax mold, etc. are made first, and then each wax mold is combined into...
