Center housing product mold

Abstract

The invention relates to a center housing product mold. The center housing product mold comprise a front press plate and a reverse press plate, wherein two casting mold core groups are respectively arranged on the front press plate and the reverse press plate; each casting mold core group comprises two symmetric casting mold cores; the upper part of the large flat surface of each casting mold coreis provided with a riser which is communicated with the corresponding casting mold core, and the lower part of the large flat surface of each casting mold core is provided with an inner gate which iscommunicated with the corresponding casting mold core; a vertical runner I and a vertical runner III are arranged on the reverse press plate, a vertical runner II is arranged on the front press plate, and the upper edge of the vertical runner I is connected with a gate cup; when the front press plate and the reverse press plate are shaped and combined, the vertical runner I is communicated with the vertical runner II, the vertical runner II is communicated with the vertical runner III, the vertical runner III is reversely pressed with a transverse runner, and the inner gate is reversely pressed with the transverse runner; an air exhaust sheet is arranged on the front press plate, and the air exhaust sheet is arranged near the casting mold core groups on the front press plate without connection.

Description

technical field [0001] The invention relates to the design and manufacture of molds in the mechanical casting industry, and is mainly aimed at a casting mold for mechanical parts, specifically a mold for intermediate shell products. Background technique [0002] At present, there are still many problems in the production of intermediate shells in the traditional machinery industry. Due to their large weight, the thickness difference between the center position and the bottom is also large, so when the intermediate shell mold is cast, the thickness is large. For example, shrinkage porosity or pores are prone to appear at the bottom of the large plane, and the process export rate is low, which seriously affects the production cost and quality of castings, and also brings waste of energy. Contents of the invention [0003] The purpose of the present invention is to provide a technical solution that can completely solve the problems of shrinkage cavity, air hole and process yi...
