Description

Improved casting head interface

Technical Field

The utility model relates to the technical field of mold manufacturing, in particular to an improved casting head interface.

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.

The casting head is a supplementary part which is added above or on the side of the casting to avoid the defect of the casting, in the casting mould, a cavity of the casting head is a container for storing liquid metal, the functions of the casting head are manifold, the casting heads with different functions have different forms, sizes and opening positions, therefore, the casting head is designed by considering the properties of casting alloy and the characteristics of the casting, and the casting head has the functions of: 1. for an alloy with small volume shrinkage during solidification (such as gray cast iron) or an alloy without concentrated shrinkage cavity (such as tin bronze), the casting head mainly functions to discharge gas in a cavity and collect molten metal mixed with inclusions or an oxide film at the front edge of liquid flow so as to reduce defects on castings; 2. for the casting requiring the control of the microstructure, the casting head can collect the metal liquid which is cooled at the front of the liquid flow, so as to avoid the appearance of a supercooled structure on the casting; 3. for alloys that shrink volumetrically during solidification and tend to form concentrated shrinkage cavities (e.g., cast steel, manganese brass, aluminum bronze, etc.), the primary function of the head is to compensate for liquid shrinkage of the molten metal in the mold cavity and shrinkage during solidification of the casting to obtain a dense casting without shrinkage cavities.

The connection between a product and a riser is straight cylinder type, when the casting head is separated, a grinding wheel piece is used for cutting a riser neck, the riser is cut to the position of half of the riser neck and then is knocked by an iron hammer, and finally the riser is separated from the product.
