Embodiment Construction

[0037] In the following description, numerous specific details are set forth in order to provide a thorough understanding of the application. However, the present application can be implemented in many other ways different from those described here, and those skilled in the art can make similar promotions without violating the connotation of the present application. Therefore, the present application is not limited by the specific implementation disclosed below.

[0038] For details, please refer to figure 1 as shown, figure 1 It is a structural schematic diagram of a mold provided by this application. exist figure 1 The present application provides a mold. After the upper mold 10 and the lower mold 20 are closed, a cavity 30 is formed inside; when the upper mold and the lower mold are closed, they have opposite butt surfaces; the upper mold 10 And / or the butt joint surface side of the lower mold 20 is also provided with a simple matching structure 40, and the simple matchi...

Abstract

The invention provides a die and a wax part. The die comprises an upper die and a lower die, wherein after the upper die and the lower die are assembled, a cavity is formed inside; when being assembled, the upper and lower dies have opposite butt joint surfaces; simple configuration structures are arranged on the sides of the butt joint surfaces of the upper die and / or the lower die and are formed by digging out part of materials of the sides of the butt joint surfaces of the upper die and / or the lower die and retaining the parts of the edges of the cavity; the sunken space formed after digging out part of materials is simple configuration space; the retained parts of the edges of the cavity are seal frames; during die assembly, the top of the seal frame on the upper die or the lower die abuts against the corresponding part of the edge of the cavity of the corresponding lower die or upper die and then the gaps in contact surfaces of the upper and lower dies are filled to improve the sealability between the upper die and the lower die and avoid the phenomenon of air leakage and then ensure the quality of die filled models.

Description

technical field [0001] The present application relates to the technical field of mechanical processing, in particular to a mold, and also to a wax piece made by using the above-mentioned mold. Background technique [0002] Mold is a processing tool used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping, stretching and other methods to obtain the required products. According to molding, molds can be divided into injection molding, compression molding, extrusion molding, injection molding, hollow molding, die-casting molding and so on. [0003] The mold generally includes a left mold and a right mold (or an upper mold and a lower mold), which can also be called a movable mold and a fixed mold (or a punch mold and a concave mold). The two parts can be separated or combined. Take out the parts when they are separated, and inject the blank into the mold cavity to form when they are closed. The mold is a p...
