Description

A wax injection mold

technical field

The invention relates to a mold, especially a wax injection mold.

Background technique

Generally, when using lost wax casting, an investment pattern made of wax is first required. In the process of making the investment pattern, the push rod is used to eject the investment molded product. Since the contact area between the ejector rod and the investment molded product is small, the investment molded product Injection molded from wax, the texture is soft, and it is easy to damage the investment molded product when taking the mold.

The invention provides a wax injection mold which can facilitate mold taking and prevent investment mold damage.

In order to achieve the above object, the technical solution adopted by the present invention is: comprising a fixed mold and a movable mold, characterized in that: the movable mold includes a movable mold base, a movable template, which is arranged on the movable mold base and is located on the A push plate that can move vertically under the movable template, a first push block and a second push block are vertically arranged on the push plate, the second push block is cylindrical, and a round hole is arranged in the middle, and the The movable template is provided with a first circular groove, a second circular groove, a first intermediate groove connecting the first circular groove and the second circular groove, and the first circular groove A first through hole is provided in the middle, and the inner wall of the first through hole is provided with a groove that matches the first push block, and a groove that matches the second push block is provided in the middle of the second circular groove. Matching second through holes, the fixed mold includes a fixed template, a first cushion block arranged on the reverse side of the fixed template, a second cushion block arranged on the reverse side of the fixed template, and the fixed template A third circular groove corresponding to the first circular groove, a fourth circular groove corresponding to the second circular groove, and a fourth circular groove corresponding to the first intermediate groove are provided on the top. Two middle grooves, a third through hole corresponding to the first through hole, a fourth through hole corresponding to the round hole, the first spacer is provided with a The first core that matches the hole and the third through hole, and the second pad is provided with a second core that matches the round hole and the fourth through hole. A sprue is arranged between the movable template and the fixed template.

Preferably, positioning pins are provided on the fixed template, and positioning pin holes matching the positioning pins are provided on the movable template.

Preferably, the wax injection mold is molded by precision casting wax injection molding.

Due to the application of the above-mentioned technical scheme, the present invention has the following advantages compared with the prior art: the present invention uses a push block to push out the product, the contact area between the push block and the product is relatively large, and it is not easy to push the product when pushing out, thereby achieving immediate It is convenient to take out the mold without damaging the purpose of the product.
