Working method of casting injection molding mold

Abstract

The invention relates to a casting injection mould for agricultural machinery. The casting injection mould comprises an upper mould, a lower mould and cavities, wherein the cavities are connected with an injection pouring gate and a sprue, the cavities comprise a first cavity and a second cavity, a baffle pillar is arranged between the first cavity and the second cavity, the baffle pillar is a column with grooves, transverse baffle blocks are arranged in the first cavity and the second cavity along the horizontal center lines of the first cavity and the second cavity, 'ao'-shaped grooves (ao is a Chinese character, meaning concave) are formed at the end parts of the baffle blocks of the first cavity and the second cavity, u-shaped grooves are formed in the surfaces of the upper mould and the lower mould along longitudinal center line of the first cavity and the second cavity, guide rods are mounted in the u-shaped grooves, the depths of the 'ao'-shaped grooves are smaller than the depths of the first cavity and the second cavity, bulges are formed on the upper mould, an fixing holes connected with the bulges in a matching way are formed in the lower mould, and a demoulding device is arranged on the lower mould.

Description

[0001] This application is a divisional application. The invention-creation name of the original application: an injection molding mold for agricultural machinery castings, application number: 201210479786.0, application date: 2012-11-23. technical field [0002] The invention relates to a mold, in particular to an injection molding mold used for manufacturing agricultural machinery castings.
