Problems solved by technology

[0004] In view of the above-mentioned prior art, the purpose of the present invention is to overcome the problems that the lost-wax casting in the prior art usually requires relatively complicated processing, which brings a lot of inconvenience to production and increases the production cost, thereby providing a method that can be divided into two parts. The mold can be closed well, so that the wax mold made has a good surface finish, and is easy to operate, degradable, and environmentally friendly wax casting mold

Abstract

The invention discloses a wax mould casting mould comprising a first half mould (2) provided with a first mould cavity (1) in an inwards-sunken mode and a second half mould (4) provided with a secondmould cavity (3) in an inwards-sunken mode. The first mould cavity (1) and the second mould cavity (3) can be matched to form a wax mould cavity, and the wax mould cavity is provided with a wax injecting hole (5) communicating to the exteriors/exterior of the first half mould and/or the second half mould. A first cavity (7) capable of storing a steel piece (6) is formed in the first half mould (2), and a second cavity (9) capable of storing a magnetic piece (8) is formed in the second half mould (4). Materials of the first half mould (2) and/or the second half mould (4) comprise polylactic acid and nano silicon dioxide. The effects that mould splitting can be achieved, closing can be well achieved, the prepared wax mould has pretty good surface smoothness accordingly, operation is easy, the degradable effect is achieved, and the environment friendly degree is high are achieved.

Description

technical field [0001] The invention relates to the field of casting moulds, in particular to wax casting moulds. Background technique [0002] Investment casting, also known as lost wax casting, includes processes such as wax pressing, wax repairing, tree formation, dipping, melting wax, casting molten metal and post-processing. Lost wax casting is to use wax to make a wax mold of the part to be cast, and then coat the wax mold with mud, which is the mud mold. After the clay mold is dried, it is fired into a pottery mold. Once fired, all the wax molds are melted and lost, leaving only the pottery molds. Generally, when the mud mold is made, the sprue is left, and then the molten metal is poured into the sprue, and after cooling, the required parts are made. In production, most of them use pressure to press the paste mold material into the mold to make the investment mold. Before pressing the investment pattern, it is necessary to apply a thin layer of mold release agent...
