Punch press mold casting blank for evanescent mold casting

Abstract

The invention discloses a punch press mold casting block for evanescent mold casting. The punch press mold casting block for evanescent mold casting comprises a lower mold and an upper mold. A feed port is formed in the upper portion of the front side of the lower mold and communicates with a lower forming groove. Connectors are arranged on the two sides and the back side of the lower mold and connected with the lower forming groove through a water inlet. Limiting rods are arranged around the upper portions of the connectors. A telescopic rod is arranged below an air cylinder. An upper forminggroove is reserved in the lower surface of the upper mold, a movable plate is arranged in the upper forming groove and fixedly connected with the telescopic rod, and through holes are reserved in theperiphery inside the movable plate. Limiting holes are reserved in the periphery of the lower surface of the upper mold. According to the punch press mold casting block for evanescent mold casting, when installation plates are cast through an evanescent mold, the evanescent mold for the installation plates with the different thicknesses is conveniently manufactured, it does not need to replace amold blank repeatedly, and when the upper mold and the lower mold are clamped, the dislocation situation can be reduced.

Description

technical field [0001] The invention relates to the technical field of lost foam mold blanks, in particular to a lost foam casting punching mold blank. Background technique [0002] Lost foam casting is a solid mold casting in which the foam plastic mold uses dry sand without binder and combined with vacuum pumping technology. It is known as the green casting process in the 21st century. When the lost foam is prepared, it needs to be made with a punch and a lost foam mold blank. The current lost foam mold base still has some problems in the production of mounting boards. For example, when making mounting boards of different thicknesses, it needs to be completed by replacing different mold bases, which will waste the energy of the laborers, and the upper mold and the lower mold There will be misalignment during the occlusal, so we propose a lost foam casting punching mold blank to solve the above problems. Contents of the invention [0003] The purpose of the present inven...
