Multi-hole vacuum casting mould component

Abstract

The invention relates to a multi-hole vacuum casting mould component which is appropriate for a vacuum casting technique. The multi-hole vacuum casting mould component comprises a mould main body, a graphic cover and a graphic ring, wherein the mould main body consists of a cuboid inner mould and four cuboid outer moulds; the interfaces, adjacent to the outer moulds, of the inner mould are mould joints of a casting mould; multiple mould holes are symmetrically distributed on the peripheral mould joints; a center hole is formed in the inner mould; the handle part of the graphic cover is inserted into the center hole in the inner mould; the graphic ring is located on the mould main body; a graphic ring hole is formed in the center of the graphic ring; the head part of the graphic cover is arranged in the graphic ring; an interval exists between the head part of the graphic cover and the graphic ring. By the adoption of the multi-hole vacuum casting mould component, the casting of multiple castings can be simultaneously completed; the structure is simpler and more reasonable; the economical efficiency is good; as the shunting and the buffering of the graphic cover are adopted, the defects of a top pouring type casting way are overcome better.

Description

technical field [0001] The invention relates to a porous vacuum casting mold assembly, which is mainly suitable for vacuum casting technology and belongs to the field of casting molds. Background technique [0002] Traditional molds generally consist of one workpiece and one pair of molds. When multiple workpieces are cast, multiple sets of molds need to be cast in turn on the turntable. When casting a batch of raw materials into multiple ingots, the operation process is complicated, and it is easy to fall due to inaccurate positioning. on the outside of the mold. [0003] For the existing combined casting mold, although multiple workpieces can be realized in a pair of molds, the structure is relatively complex, the mold production cost is high, the assembly process is complicated, the assembly precision is high, assembly misalignment is easy to occur, and the demoulding is relatively complicated , affects the overall operating speed, so it is not suitable for casting casti...

[0002] Traditional molds generally consist of one workpiece and one pair of molds. When multiple workpieces are cast, multiple sets of molds need to be cast in turn on the turntable. When casting a batch of raw materials into multiple ingots, the operation process is complicated, and it is easy to fall due to inaccurate positioning. on the outside of the mold

[0003] For the existing combined casting mold, although multiple workpieces can be realized in a pair of molds, the structure is relatively complex, the mold production cost is high, the assembly process is complicated, the assembly precision is high, assembly misalignment is easy to occur, and the demoulding is relatively complicated , affecting the overall operating speed, so it is not suitable for casting castings with simpler structures

For castings with simple structure and uniform wall thickness, the top pouring method with simple molding process and convenient mold manufacturing is generally used. Fast, but the thermal impact on the mold wall is also large, and the filling process is not stable, and defects such as slag inclusions will occur

[0004] On the other hand, metal molds should generally be made of metal materials with good thermal conductivity and good mechanical properties, because the mold will undergo repeated heating and cooling during use, which will cause growth and increase the volume. Decreased density, decreased strength, prone to cracks and cracks in the internal cavity, which will lead to increased pores inside the ingot and affect the performance of the ingot

[0005] Chinese Patent No. 201010517266 discloses a patent titled "A Vacuum Casting Mold Assembly". This mold can cast multiple ingots at one time, but it injects the melt into the ingot mold through the middle injection pipe and the channel structure. The mold structure The design is complicated and the structure is not tight enough, and the above-mentioned defects in the prior art are not overcome

[0006] Chinese Patent No. 201220211292 discloses a patent named "Vacuum Ingot Casting Device". The mold is equipped with a turntable, and there are multiple ingot molds on the turntable. The melt is injected into the ingot mold from the vacuum box through the ingot tube, and can be rotated by the turntable. Casting multiple ingots, but its structural design is more complicated, and it also needs to drive the turntable, which requires high positioning accuracy, and does not overcome the above-mentioned defects in the prior art
