Embodiment Construction

[0022] As shown in the figure, an investment mold for casting quick joints includes a trumpet-shaped pouring body 1, and the bottom end of the pouring body 1 expands radially downwards gradually to form a feeding body 5, which is connected to a triangular prism-shaped mold There are three casting bodies 3 evenly distributed around the casting body 1. Of course, the shape of the die head 2 and the number of casting bodies 3 can be changed, but it must be satisfied that the die head 2 is a column with a positive multi-deformation cross section. body, to ensure that the casting body 3 is evenly distributed, so that they dissipate heat evenly, and there is no difference in products.

[0023] The casting body 3 has the same shape as the quick connector to be cast, and of course the casting body 3 can also be in other shapes. When it is tubular, the length is 10-50 cm, the outer diameter is 5-30 cm, and the cross-sectional shape can be arbitrary. The ratio of the distance between th...

Abstract

The invention discloses a fired mold, which comprises a trumpet casting body, a mold head connected with the bottom end of the casting body and a plurality of cast bodies. The mold head is a cylinder of which the cross section is polygonal; the number of the cast bodies is the same as the edge number of the bottom of the mold head; all the cast bodies are uniformly distributed around the casting body; and the bottom of each cast body is opposite to one side wall of the mold head and is connected with the side wall through bridging. The invention also discloses a precision casting process by utilizing the fired mold. The bridge of the fired mold is connected with the bottom of the cast bodies, so metal fluid flows to the top from the bottom of a shell, the casting is full, the air exhaust is full, the one-time casting yield is improved by 20 percent, the cast product has good quality, and the qualification rate is 98 percent.

Description

technical field [0001] The invention relates to the technical field of precision casting, in particular to an investment mold and a precision casting process using the investment mold. Background technique [0002] Investment casting (precision casting), also known as "lost wax casting", usually refers to making a pattern from a fusible material, coating several layers of refractory material on the surface of the pattern to make a shell, and then melting the pattern and discharging the shell to obtain The casting mold without parting surface can be filled with sand and poured after high-temperature roasting. Since patterns are widely made of waxy materials, investment casting is often referred to as "lost wax casting". [0003] The first process of investment casting production is to make investment molds, which are used to form refractory shell models, so to obtain castings with high dimensional accuracy and surface finish, the investment mold itself should first have high...
