Abstract

The utility model discloses a production differential mechanism sand control eye mould, including positive clamp plate and back pressure board, the correspondence punishment of positive and negative clamp plate below do not is equipped with the same foundry goods module, the foundry goods module is connected with big rising head, foundry goods module one side of positive and negative clamp plate is equipped with pouring basin and cassette module perpendicularly, and the top of positive and negative clamp plate, the middle part that positive and negative clamp plate was located to the cassette module are located to the pouring basin, the down sprue connection is passed through to pouring basin and cassette module on the back pressure board, and positive clamp plate foundry goods module below is being equipped with the cross gate, foundry goods module central authorities are equipped with the loam core locating piece rather than the intercommunication. The utility model discloses add square cassette and horizontal down sprue overlap joint on the down sprue of mould, can thoroughly solve the technique of blowholes and slag blister phenomenon, add one back pressure flow gate simultaneously below the rising head, can realize the slow process of filling the type of molten iron to avoid the impact force to the sand mould.

Description

A kind of production anti-sand holes mould of differential mechanism

Technical field

This utility model belongs to machine casting field, relates to the casting mould of a kind of component of machine, specifically a kind of production anti-sand holes mould of differential mechanism.

Background technology

At present, in the differential casing of traditional mechanical industry makes, yet suffer from many problems, owing to differential mechanism weight is relatively big, required precision is high, and the thickness difference between each position is also bigger, hence in so that when difference shell die casting, at cast(ing) surface, size sand slag blister occurs, had a strong impact on the quality of foundry goods, also bring raw-material waste simultaneously.

Summary of the invention

Goal of the invention: the purpose of this utility model is in that for the deficiencies in the prior art, it is provided that a kind of production anti-sand holes mould of differential mechanism.

Technical scheme: in order to reach foregoing invention purpose, this utility model is specifically performed by: a kind of production anti-sand holes mould of differential mechanism, including pressure plate and counter, below positive counter, corresponding position is respectively equipped with identical foundry goods module, and described foundry goods module is connected to big rising head；The foundry goods module side of positive counter is vertically provided with cup and filter module, and the top of positive counter is located at by cup, filter module is located at the middle part of positive counter；Cup and filter module in counter are connected by sprue, and pressure plate foundry goods module is connected with cross gate；Foundry goods module central is provided with the loam core locating piece communicated therewith.

Wherein, described foundry goods module is be made up of the submodule of 2 specular.

Wherein, the perpendicular bisector of described foundry goods module centrage is provided with the big rising head that the two ends of bottom are connected respectively with submodule.

Wherein, described big rising head is cylindrical stage shape.

Wherein, there is the oblique oblique angle of 10 ~ 15 ° bottom described submodule and big rising head.

Wherein, described big rising head is connected with back-pressure ingate.

Beneficial effect: this utility model is compared with conventional art, plus quadratic filter sheet and the overlap joint of running channel anyhow on the sprue of mould, can thoroughly solve the technology of sand holes and slag blister phenomenon, below rising head, add one back-pressure ingate simultaneously, molten iron can be realized and fill the process of type slowly, thus avoiding the impulsive force to sand mold.
