Description
Technical Field
The invention belongs to the field of precision investment casting, and particularly relates to a precision investment casting square runner mold with a variable structure.
Background
The investment precision casting process has a long history and is widely applied to the production of various types of castings such as steel, copper alloy, aluminum alloy, titanium alloy, ball-milling cast iron and the like. The casting produced by the process has excellent size precision and surface smoothness, and the subsequent machining cost of the casting is saved. The structure of the investment casting runner is an important factor for ensuring smooth filling of metal, and a runner matched with the structure of the investment casting runner needs to be designed according to the structural characteristics of a product. The square grid runner is a widely used runner type. The grid structure has wide applicability and higher strength. However, since the products themselves have different structures, the separate fabrication of the runner mold for each product undoubtedly results in an increase in production cost. Therefore, the design of the pouring gate die capable of adjusting the grid structure and the size can save material cost, labor consumption and production efficiency, and has very important significance.
Disclosure of Invention
The invention provides a variable-structure investment precision casting square-frame runner mold for solving the problems in the prior art.
In order to achieve the purpose, the invention adopts the following technical scheme: the utility model provides a changeable investment precision casting square frame waters mould of structure, it includes a plurality of mould upper covers, a plurality of mould lower covers and a plurality of loose piece, a plurality of mould lower covers link to each other in proper order along the horizontal direction, and every mould is covered all to inlay under and has a plurality of loose pieces, the loose piece is fixed through mould upper cover and mould lower cover, the quantity of mould upper cover is the same with mould lower cover quantity, and every mould upper cover all links to each other with the mould lower cover that corresponds is fixed, and one of them mould is covered and has been seted up the wax injection mouth.
Furthermore, side baffles are arranged on two sides of the pouring gate mold.
Furthermore, the lower cover of the mould is connected with a core bar, and the core bar passes through the wax injection opening.
Furthermore, the cross section of the loose piece is rectangular or fan-shaped.
Further, the number of the lower mold covers is 5-7.
Compared with the prior art, the invention has the beneficial effects that: the invention solves the problems that the prior investment precision casting square frame pouring channel mould is of an integrated structure, and the grid structure and the size of the mould cannot be freely adjusted. The invention can realize that the square frame pouring channels with different sizes and different grid structures are pressed by using one set of die according to the structural characteristics of products. The square pouring channels with different structures and sizes can be pressed by combining different movable blocks and adjusting the number of the upper cover and the lower cover of the mould. The invention can adjust the loose piece according to the actual requirement, presses the pouring channel meeting the structural requirement, and does not need to cut and repair the pouring channel.
