Easy-demolding treatment method for inner surface of casting mold

Abstract

The invention discloses an easy-demolding treatment method for the inner surface of a casting mold. The easy- demolding treatment method comprises the following steps: S1, fixing the mold: placing themold needing to be coated with demolding liquid on the upper surface of a working table, starting a first motor, driving a first lead screw to rotate by the first motor, and oppositely moving positioning clamping plates to clamp and fix the mold; and S2, carrying out position coarse adjustment, specifically, driving a second lead screw to rotate through a second motor, and driving a movable support through a threaded sleeve to move on the second lead screw. According to the easy-demolding treatment method for the inner surface of the casting mold, the first lead screw and the positioning clamping plates are arranged to fix the mold, the second lead screw and an insection rail are used in cooperation, the horizontal position of a coating frame can be changed, position adjustment is accurate, a handle is held by hand, a guide column drives a coating device to integrally move downwards and rotate, control is convenient, the spraying position and angle can be manually adjusted according to the position of the inner wall of the mold, and use is flexible.

Description

technical field [0001] The invention relates to the technical field of demolding of casting molds, in particular to a method for easy demolding treatment of the inner surface of a casting mold. Background technique [0002] Casting mold means that in order to obtain the structural shape of the part, other easy-to-form materials are used to make the structural shape of the part in advance, and then the mold is placed in the sand mold, so a cavity with the same structural size as the part is formed in the sand mold. Then pour a fluid liquid into the cavity, and after the liquid cools and solidifies, it can form a part exactly the same as the shape and structure of the mold. Casting molds are an important part of the casting process. In the process of casting molds, in order to facilitate the demoulding after casting, the inside of the mold needs to be coated with a release agent. However, the current market methods for easy demoulding treatment of the inner surface of casting...

Problems solved by technology

In the process of casting molds, in order to facilitate the demoulding after casting, the inside of the mold needs to be coated with a release agent. However, the current market methods for easy demoulding treatment of the inner surface of casting molds have the following problems in the operation process: a. common Most of the mold release agents are sprayed, so that the coating efficiency is fast, but when encountering a mold with a relatively complex structure, the mold release agent cannot completely cover the mold cavity, especially some concave notches, In this way, it is easy to cause damage to the workpiece during demoulding; b. When the common mold release agent is sprayed on the inside of the mold, in order to ensure that the inner corners of the mold are covered with the mold release agent, it is often applied multiple times in the same place. spraying, which will cause a lot of waste of release agent

[0004] Although this application solves the problems in the background technology to a certain extent, in this application, the support column supports the tray, and the coating device cannot move up and down, left and right, and the corners cannot be evenly coated during the coating process. At the same time, the mold The side wall cannot be coated, only the bottom surface can be coated, and the usable area is limited
