Description

Shutter mount pad wax matrix mould

Technical Field

The utility model relates to an accurate parts manufacture equipment field, concretely relates to valve mount pad wax matrix mould.

Background

Investment casting mainly comprises the processes of mould manufacturing, wax mould manufacturing, shell mould manufacturing, drying, roasting, pouring, solidifying and the like. The wax pattern is a pattern for forming a cavity of a casting, and in order to obtain a casting with high dimensional accuracy and surface smoothness, the wax pattern itself should have high dimensional accuracy and surface smoothness. Factors influencing the dimensional accuracy of the wax pattern in the manufacturing process of the wax pattern are complex, and process parameters are more, so that the dimensional accuracy change range of the wax pattern is larger. In addition, the wax pattern itself should be as easy as possible to perform the subsequent processes such as shell making. In order to obtain a high-quality wax pattern, besides a good profiling (a mold for pressing the wax pattern), a proper molding material (mold material for short) and a reasonable molding process must be selected.

At present, chinese patent publication No. CN204276805U discloses a precision casting wax mold, which includes a lower mold and a movable core assembled on the lower mold in a vertically guiding manner, and further includes a mold release pushing member having an upper end for force-transfer fitting with a corresponding wax pressing machine, and the mold release pushing member has at least one top extending vertically for pushing the upper end of the movable core.

Although the precision casting wax mold can utilize the wax pressing machine to transmit force to the demolding pushing part when the wax mold and the movable core are required to be demolded, the ejector rod on the demolding pushing part pushes the movable core to separate the movable core from the wax mold, and the wax mold and the movable core are demolded through the mechanical force of the wax pressing machine, the labor intensity of operators can be reduced, in addition, the ejector rod and the movable core are in pushing fit to separate the wax mold from the movable core, the ejector rod cannot contact with the wax mold, the problem that the wax mold is easy to damage is solved, and the precision casting wax mold is not suitable for manufacturing the wax mold which is not at the same horizontal height.
