Description

Core box for improved water inlet sprue

Technical Field

The utility model relates to the technical field of mold manufacturing, in particular to an improved core box for a water inlet sprue.

Background

The industrial production of the die is used for obtaining various dies and tools of required products by methods such as injection molding, blow molding, extrusion, die casting or forging forming, smelting, stamping and the like. In short, a mold is a tool used to make a shaped article, the tool being made up of various parts, different molds being made up of different parts. The method realizes the processing of the appearance of the article mainly by changing the physical state of the formed material, and the article is called as 'industrial mother'.

The blank is formed into a tool with a specific shape and size under the action of external force. The method is widely applied to blanking, die forging, cold heading, extrusion, powder metallurgy part pressing, pressure casting and the forming processing of compression molding or injection molding of products such as engineering plastics, rubber, ceramics and the like. The die has a specific contour or cavity shape, and the blank can be separated (blanked) according to the contour shape by applying the contour shape with the cutting edge. The blank can obtain a corresponding three-dimensional shape by using the shape of the inner cavity. The mold generally comprises a movable mold and a fixed mold (or a male mold and a female mold), which can be separated or combined. When the blank is closed, the blank is injected into the die cavity for forming. The die is a precise tool, has a complex shape, bears the expansion force of a blank, has higher requirements on structural strength, rigidity, surface hardness, surface roughness and processing precision, and the development level of die production is one of important marks of the mechanical manufacturing level.

In the production process of a mold, molten steel is often required to be poured into the mold, a method frequently adopted in the prior art is to cut a water inlet sprue on a sand mold, the surface of the cut water inlet sprue is often rough, floating sand in the sand mold is easy to mix into the molten steel during molten steel casting, and the quality of a product is often influenced by the floating sand mixed into the molten steel.
