Bilateral filling gating system

Abstract

The invention discloses a bilateral filling gating system which comprises a stationary die and a movable die, wherein a stationary die insert and a movable die insert are also respectively connected onto the stationary die and the movable die, sliding block bushes which are matched with the stationary die insert and the movable die insert are arranged, sliding blocks which are matched with the sliding block bushes are arranged, the stationary die insert, the movable die insert and the sliding blocks commonly form a cavity, the sliding blocks can laterally move in the sliding block bushes, inclination angles alpha are arranged on the outlines of the sliding blocks along the movement direction of the sliding blocks, so the whole front ends of the sliding blocks are conical, and the value range of the inclination angles is 1-2 degrees; the bilateral filling gating system is characterized in that the left side and the right side of the cavity are respectively provided with flow gates 6; and a plurality of the flow gates 6 are arranged. The invention provides the bilateral filling gating system which has a simple structure and an ingenious design, adopts a synchronous bilateral filling mode, can shorten the filling process and time by a half, has small energy loss, and can obviously improve the casting quality and production efficiency.

Description

technical field [0001] The invention relates to a pouring system, in particular to a double-side filling pouring system. Background technique [0002] In the process of casting die-casting production, the common pouring method is to fill from one side of the casting, and set up overflow grooves, exhaust grooves and other auxiliary exhaust on the other side. Since the material in the molten state (take aluminum liquid as an example) needs to flow from one side of the mold cavity to the other side, the process is longer, so the momentum and heat energy loss of the aluminum liquid are large during the filling process, so when filling At the end of the mold (that is, the end of the cavity), casting defects such as cold shuts, air holes, keyholes, and flow marks often appear, and the resulting casting defects account for a large proportion in the actual production process. Traditionally, the pouring method of simultaneous filling on both sides is not used, because simultaneous f...

Problems solved by technology

Traditionally, the pouring method of filling on both sides at the same time is not used, because filling on both sides at the same time will have a relatively strong impact on the slider and other parts, and it is easy to cause the slider to lock and cannot move normally.
