Method for assembling loose piece groups of annular mold

Abstract

The invention discloses a method for assembling loose piece groups of an annular mold. Before the annular mold is assembled, a positioning ring is manufactured according to the structural shape of the loose piece groups, the inner circle surface of the positioning ring is corresponding to the corresponding matching surfaces of the loose piece groups in shape, and the outer circle surface of the positioning ring is corresponding to the corresponding matching surfaces of upper and lower half molds of the annular mold in shape. During the assembly, the loose piece groups are clamped into the positioning ring one by one and are positioned, and the positioning ring with the loose piece groups is assembled together with the upper and lower half molds of the annular mold. According to the method, the loose piece groups are positioned through the positioning ring, and then the upper and lower molds are assembled, so that the positioning operation is simple and quick, the assembled mold can be prevented from shifting, and the assembly efficiency of the mold is improved.

Description

technical field [0001] The invention belongs to the technical field of investment casting precision casting, and in particular relates to a mold assembly method with movable block groups. Background technique [0002] In investment precision casting, due to the wide variety of product shapes, loose block groups are often used to solve complex structural problems during mold processing and assembly. There are problems such as inaccurate positioning and wrong shape, which affect the normal assembly of the mold. For example, there are as many as 52 movable block groups in a certain ring casting, and it is very difficult to position during mold assembly. Therefore, the assembly problem of this type of mold has become a problem. A technical problem that urgently needs to be solved in the foundry industry. In the existing technology, there are many studies on the positioning of the loose block. For example, Chinese patent 201320163062.5 discloses a positioning mechanism for the lo...

Problems solved by technology

[0002] In investment precision casting, due to the wide variety of product shapes, loose block groups are often used to solve complex structural problems during mold processing and assembly. There are problems such as inaccurate positioning and wrong shape, which affect the normal assembly of the mold. For example, there are as many as 52 movable block groups in a certain ring casting, and it is very difficult to position during mold assembly. Therefore, the assembly problem of this type of mold has become a problem. A technical problem that urgently needs to be solved in the foundry industry. In the existing technology, there are many studies on the positioning of the loose block. For example, Chinese patent 201320163062.5 discloses a positioning mechanism for the loose block of the mold. The side wall is provided with a first movable block groove for clamping the first magnetic movable block and a second movable block groove for clamping the second magnetic movable block. The height of the first movable block groove is greater than or equal to that of the second magnetic movable block. A magnetic movable block, the height of the second movable block slot is greater than or equal to the second magnetic movable block, the patent uses the clamping slot to limit the first magnetic movable block and the second magnetic movable block, so that the movable block Accurate positioning, small shaking, not easy to bump in the mold

Although the patented technology realizes the positioning of the movable blocks, the structure is relatively simple due to the small number of movable blocks. It is still difficult to use this technology for positioning and assembly when the ring mold has a large number of movable blocks.
