Abstract

The utility model relates to a bimetal drum the gating system, a serial communication port, including being tubaeform sprue and being annular cross gate rather than the sub -unit connection, the upper right side of cross gate is equipped with waters in rather than being connected and being annular evenly distributed along the cross gate. The beneficial effects of the utility model are that: owing to adopted the ring gate to introduce the molten iron through the interior tangent line that waters, the molten iron temperature in the die cavity is even, and the steel sheet fuses, and the brake rim tissue is even, and the performance improves.

Description

A kind of bimetallic drum running gate system

Technical field

The utility model relates to a kind of running gate system, particularly relates to a kind of bimetallic drum running gate system, belongs to auto parts manufacture field.

Background technology

Bimetallic drum produces with horizontal mo(u)lding line, first makes sand mold up and down, be then fixed on by alignment pin on lower sand mold, lower steel plate, utilizes steel plate mesopore to lead, is accurately located by steel plate, under in drag, guarantee not collide with in lower steel plate process lower sand mold, model and steel plate keep concentric, then mention alignment pin, mould assembling, the high temperature liquid iron of more than 1400 DEG C is incorporated in the die cavity between upper and lower sand mold by running gate system, high temperature liquid iron is all contacted with steel plate, reach the object that fusion is good.

In the running gate system (see accompanying drawing 1,2) of prior art, molten iron introduces die cavity between upper and lower sand mold through the second sprue 31 by a cast gate 41 along cross gate 21 after the first sprue 11 enters running gate system, casting sprue position is easily overheated, uneven microstructure, foundry goods cylindrical wall is thin, being difficult to by riser feeding, easily there is the defects such as shrinkage porosite in foundry goods.

Utility model content

The utility model, for the deficiencies in the prior art, provides a kind of bimetallic drum running gate system.

The technical scheme that the utility model solves the problems of the technologies described above is as follows:

A kind of bimetallic drum running gate system, is characterized in that, comprise the sprue of flare and be connected ringwise cross gate with its underpart, and the upper right side of described cross gate is provided with coupled and along cross gate equally distributed tangent line ingate ringwise.

The beneficial effects of the utility model are: owing to have employed ring gate, and introduce molten iron by ingate tangent line, and the molten iron temperature in die cavity is even, and steel plate fuses, brake rim even tissue, and performance improves.

Detailed description of the invention

Be described principle of the present utility model and feature below in conjunction with example, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

A kind of bimetallic drum running gate system, comprises the sprue 1 of flare and is connected ringwise cross gate 2 with its underpart, and the upper right side of described cross gate 2 is provided with coupled and along cross gate 2 equally distributed tangent line ingate 3 ringwise.

The course of work of above-mentioned running gate system is as follows:

1) first make sand mold up and down, then alignment pin is fixed on lower sand mold, as shown in Figure 5, lower steel plate, utilizes steel plate mesopore to lead, is accurately located by steel plate, under in drag, guarantee not collide with in lower steel plate process lower sand mold, sand mold die cavity and steel plate keep concentric;

2) alignment pin is mentioned, mould assembling;

3) high temperature liquid iron of more than 1400 DEG C is introduced running gate system through sprue 1, after molten iron is full of circular cross-runner 2, evenly be incorporated in the die cavity between upper and lower sand mold by tangent line ingate 3 simultaneously, high temperature liquid iron is contacted with steel plate, reach the object that fusion is good;

4), after treating the shaping cooling of foundry goods in die cavity, remove upper and lower sand mold, foundry goods completes.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.

Claims

1. a bimetallic drum running gate system, is characterized in that, comprise the sprue of flare and be connected ringwise cross gate with its underpart, and the upper right side of described cross gate is provided with coupled and along cross gate equally distributed tangent line ingate ringwise.
