A precision casting wax pressing device

Abstract

The invention discloses a precision casting wax pressing device. The precision casting wax pressing device comprises a working table; the working table is provided with a lower die body; the lower diebody is correspondingly provided with an upper die body; the upper die body comprises an upper die; a limiting plate is arranged on one side of the upper die; an upper connection plate is arranged onone side of the limiting plate and provided with an upper semicircular groove; the lower die body comprises a lower die which is arranged on the working table; a lower connection plate is arranged onone side of the lower die and provided with a lower semicircular groove; the limiting plate is inserted in the lower die; the upper semicircular groove and the lower semicircular groove are connectedto form a pouring opening; the lower connection plate and the upper connection plate are connected to form a buffer belt; the upper connection plate is provided with a cutting device; the buffer beltcomprises an upper buffer belt body and a lower buffer belt body; and the upper buffer belt body and the lower buffer belt body are connected to form a buffer hole and internally provided with symmetrical boss belts. Through arrangement of the upper buffer belt body and the lower buffer belt body, wax paste cannot be splashed when poured, and the wax mold quality is improved.

Description

technical field [0001] The invention relates to the technical field of precision casting, in particular to a precision casting wax pressing device. Background technique [0002] Investment casting is also called "lost wax casting". Investment casting usually refers to making patterns from fusible materials, covering the surface of the pattern with several layers of refractory materials to make a shell, and then melting the pattern and discharging the shell, so as to obtain a mold without a parting surface. After high-temperature roasting Ready-to-sand casting casting solution. Since patterns are widely made of waxy materials, investment casting is often referred to as "lost wax casting". During the filling process of wax materials, waxing equipment has requirements for temperature, pressure of waxing equipment and wax injection equipment. It is stipulated that when the wax slurry enters the mold from the sprue, since the existing sprue is mostly on the top or side of the m...

Problems solved by technology

Since patterns are widely made of waxy materials, investment casting is often referred to as "lost wax casting". During the filling process of wax materials, waxing equipment has requirements for temperature, pressure of waxing equipment and wax injection equipment. It is stipulated that when the wax slurry enters the mold from the sprue, since the existing sprue is mostly on the top or side of the mold, direct wax injection is easy to cause the wax slurry to splash, making the surface quality of the wax mold poor. The present invention proposes a precision casting wax pressing device for solving the above problems
