AI Technical Summary

Technical Problem

In existing three-plate molds, the material cake and main gate are prone to getting stuck in the fixed mold plate, resulting in many failures, low efficiency, and many holes in the product, leading to low mold-making efficiency and high cost.

Method used

The traditional three-plate mold is adjusted to a two-plate structure of moving mold and fixed mold. The material cake enters the central gate through the runner and enters the mold cavity between the moving mold and fixed mold. The two-plate structure of moving mold and fixed mold simplifies the mold design, the material cake is closer to the casting, the pressure transmission is more effective, and the product porosity is reduced.

Benefits of technology

It improved casting production efficiency, reduced product porosity, simplified the mold-making process, saved mold material, and reduced production costs.

[0004] Therefore, the utility model provides a center feeding foundry mould. CONTENT OF THE UTILITY MODEL

[0005] The utility model discloses a center feeding foundry mould adjusts the traditional three-plate mould structure to be two-plate mould of fixed mould and movable mould, and the material cake enters the center sprue through the runner, enters the first mould cavity and the second mould cavity between the movable mould and the fixed mould through the center sprue, and is shaped into the casting, and because the material cake is close to the casting, it is beneficial to the transmission of the boost pressure, from the casting angle, can reduce the product hole, and the casting is more dense, because adopting two-plate structure, the fault is less, and the casting production efficiency is improved, from the mould making angle, compared with the three-plate mould, the new mould structure is simpler, improves the mould making efficiency and profit, and the mould material is less, saves the cost, and the problems in the background art can be solved effectively.

[0006] In order to realize the above-mentioned purpose, the utility model adopts the technical scheme that:

[0007] A center feeding foundry mould, including movable mould and fixed mould, one side of movable mould and one side of fixed mould are connected, first mould cavity is equipped on one side of movable mould close to fixed mould, second mould cavity is equipped on one side of fixed mould close to movable mould, first mould cavity and second mould cavity are communicated;

[0008] One end of movable mould and fixed mould is equipped with center sprue in common, movable mould, fixed mould are equipped with material cake on one end close to center sprue.

[0009] By adopting the technical scheme, the traditional three-plate mold structure is adjusted to a two-plate mold structure of a movable mold and a fixed mold, the material cake enters a center gate through a flow channel, enters the first mold cavity and the second mold cavity between the movable mold and the fixed mold through the center gate, and is formed into a casting, so that product holes can be reduced, the casting is more compact, and production efficiency is improved.

[0010] Specifically, the material cake enters the center gate through the flow channel.

[0011] Specifically, the center gate is in communication with the first mold cavity and the second mold cavity.

[0012] Specifically, the movable mold and the fixed mold are further provided with a slag ladle.

[0013] The center feeding casting mold has the advantages that the traditional three-plate mold structure is adjusted to a two-plate mold structure of a movable mold and a fixed mold, the problem that the material cake and the main gate in the fixed mold plate are easily stuck in the fixed mold plate and do not fall naturally in the prior art, resulting in many faults and low efficiency is solved, the material cake is closer to the casting in the mold cavity, the pressure is more easily transmitted into the casting, product holes can be reduced, the casting is more compact, production efficiency is improved, the mold making efficiency is effectively improved, mold material is saved, and cost is saved.
