Abstract

The invention provides a paper pouring gate pipe for casting. The paper pouring gate pipe for casting comprises two symmetrical semicircular paper pouring gates. Each semicircular paper pouring gate comprises a pipe wall, an adhesion wall, a socket end and an inserting end, wherein the pipe wall is of a semicircular arch structure, one end of the pipe wall is provided with the socket end, the other end of the pipe wall is provided with the inserting end, the inner diameter of the socket end is larger than or equal to the outer diameter of the inserting end, and the adhesion wall is horizontally distributed on the outer side of the pipe wall and the socket end along the diameter face of the semicircular arch structure. The invention further provides a preparation method of the paper pouringgate pipe for casting. The preparation method comprises the steps of bonding and trimming. The problems that the paper pouring gate pipe is difficult to form and low in forming shaping efficiency aresolved, and an existing pulp molding technology can be directly adopted for preparation. The preparation technology is simple, forming and shaping are easy, the efficiency is high, limitation from the diameter and the structure of the pouring gate pipe is avoided, and the paper pouring gate pipe with the excellent quality can be produced by applying the method.

Description

technical field [0001] The invention relates to the field of casting, in particular to a paper sprue pipe for casting and a preparation method thereof. Background technique [0002] The paper sprue tube is a new casting gating system component that replaces the traditional ceramic sprue tube. The current technology has two preparation methods, one is the pulp molding method, the paper sprue tube raw material is made into a slurry, and the pulp molding method is used to absorb and form a hollow tube, and after hot pressing, the obtained Paper sprue tube for casting, CN201510723033.3 "Paper sprue tube for casting and its manufacturing method" discloses a paper sprue tube and its manufacturing method, the paper sprue tube prepared by this method achieves good The molding effect of the mold is difficult and difficult to shape, especially the paper sprue tube with a small diameter, which is easy to block when forming, and its tube wall is thinner than the large diameter paper sp...
