Abstract
The utility model discloses a forming technology structure of sand mould dead head is applied to swage mould (1), swage mould (1) be equipped with main water (4) to and and the corresponding casting die cavity of casting product (8) shape, dead head (5) adopt the manufacturing of same kind of molding sand technology with the casting die cavity to through special frock or mould and the synchronous one -step integral molding of casting die cavity. Adopt above -mentioned technical scheme, has left out prefabrication, deposit and the installation of dead head, practiced thrift the recruitment, avoided professional equipment to drop into, practiced thrift the production place, also avoided dead head precast process in the molding sand extravagant, at sand mould thermoforming in -process, the dead head forming process in, but the make full use of waste heat reduces the production energy consumption, the gating system's noncongestion is guaranteed to dead head and casting die cavity seamless connection, avoids defects such as the dead head floats.
Description
Technical field
This utility model belongs to the technical field of casting technique and equipment thereof.Water more specifically, this utility model relates to a kind of sand mold
The moulding process of rising head.It addition, this utility model further relates to be applied to the process structure of this technique.
Background technology
At casting industry, during moulding produces, because Technology is limited, during moulding, need prefabricated dead head, in order to casting molten metal
Inject sand mold die cavity smoothly.This production Technology suffers from the drawback that
1, dead head is prefabricated: before moulding, need to make dead head in advance, and foundry enterprise need to configure the production dead head equipment of necessity,
Need to be accomplished manually the making of dead head and drying and processing；
2, dead head deposit: dead head prefabrication process needs certain place to carry out the prefabricated deposit of dead head；
3, dead head is installed and feature: before cast, need to install dead head in advance.In dead head installation process, the loose sand of generation is residual
Existing in casting mold cavity, during cast, loose sand directly incorporates in cast article, affects cast article quality.When dead head is installed it is
Loose sand is avoided to accumulate, it is necessary to carry out purging cleaning in time.
There is gap between dead head after installation and the contact surface of casting mold cavity, cause dead head floating during cast or molten metal passes through
Gap is excessive, there is potential safety hazard.
Utility model content
