Abstract

The invention discloses a forming technology structure for a sand mold casting head. The forming technology structure is applied to an iron mold (1). The iron mold (1) is provided with a main pouring gate (4) and a casting cavity corresponding to a cast product (8) in shape. The same sand mold technology is adopted for manufacturing the casting head (5) and the casting cavity, and the casting head (5) and the casting cavity are synchronously and integrally formed at a time through a special tool or die. By means of the above technical scheme, prefabrication, storage and installation of the casting head are omitted, labor is saved, input of special equipment is avoided, the production field is saved, and molding sand waste in the casting head prefabricating process is avoided. In the sand mold thermal forming process and the casting head forming process, waste heat can be sufficiently utilized, and the production energy consumption is reduced. The casting head and the casting cavity are in seamless connection, smoothness of a pouring system is ensured, and the defects such as floating of the casting head are avoided.

Description

The moulding process of sand mold dead head and process structure thereof
Technical field
The invention belongs to the technical field of casting technique and equipment thereof. In particular, it relates to the moulding process of a kind of sand mold dead head. In addition, the present invention also relates to the process structure being applied to this technique.
Background technology
At casting industry, during moulding is produced, because Technology is limited, during moulding, need prefabricated dead head, so that the smooth injection sand mold die cavity of casting metal liquid. There is following drawback in this production technology:
1, dead head is prefabricated: before moulding, need to make dead head in advance, and foundry enterprise need to configure necessary production dead head equipment, it is necessary to manually completes making and the drying and processing of dead head;
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 remains in casting mold cavity, and during cast, loose sand directly incorporates in cast article, affects cast article quality. When installing dead head, in order to avoid, loose sand is long-pending to be stayed, it is necessary to carry out blowing in time clearing away reason.
Dead head after installation and there is gap between the contact surface of casting mold cavity, causes during cast that dead head is floating or molten metal is excessive by gap, there is potential safety hazard.
Summary of the invention
The present invention provides the moulding process of a kind of sand mold dead head, its objective is to simplify the manufacturing process of mould dead head.
In order to realize above-mentioned purpose, the technical scheme that the present invention takes is:
The moulding process of the sand mold dead head of the present invention, is applied to iron pattern tool; Described iron pattern tool is provided with Zhu Jiao road, and the casting mold cavity corresponding to cast article shape; Described dead head and casting mold cavity adopt same molding sand process to manufacture, and by special tooling or mould disposal integral molding synchronous with casting mold cavity.
In order to realize the goal of the invention identical with technique scheme, present invention also offers the technical scheme of the process structure being applied to the above technique:
Described dead head is arranged on the upper end in Zhu Jiao road.
Described dead head and junction, Zhu Jiao road arrange filtering net.
Described forming process structure is shaping for precoated sand, resin sand is shaping, tide mould sand is shaping.
Described iron pattern tool is provided with penetrates Sha Kou.
Between described Zhu Jiao road and casting mold cavity, between adjacent casting mold cavity, it is connected by cross gate.
The present invention adopts technique scheme, eliminates prefabricated, the deposit of dead head and installs, saved recruitment, avoid specific equipment and drop into, saved production place, it also avoid the waste of dead head prefabrication process Sand; In sand mold thermoforming process, in described dead head moulding process, waste heat can be made full use of, reduce production energy consumption; Dead head and casting mold cavity seamless link, it is ensured that gating system unimpeded, the defect such as avoid dead head floating.

Embodiment
Compare accompanying drawing below, by the description to embodiment, the specific embodiment of the present invention is described in further detail, to help the technician of this area that invention design, the technical scheme of the present invention are had more complete, accurate and deep understanding.
The present invention realizes dead head and casting mold cavity integrated molding. It is applicable to various casting technique field, it is particularly useful for that precoated sand is shaping, resin sand is shaping, tide mould sand is shaping.
As shown in Figure 1, Figure 2 with the structure of the present invention expressed by Fig. 3, it is the forming process structure of a kind of sand mold dead head, it is applied to iron pattern tool 1; Described iron pattern tool 1 is provided with Zhu Jiao road 4, and the casting mold cavity corresponding to cast article 8 shape.
In order to solve prior art Problems existing and overcome its defect, it is achieved simplifying the goal of the invention of the manufacturing process of mould dead head, the technical scheme that the present invention takes is:
As shown in Figure 1 to Figure 3, the moulding process of the sand mold dead head of the present invention, described dead head 5 and casting mold cavity adopt same molding sand process to manufacture, and by special tooling or mould disposal integral molding synchronous with casting mold cavity.
Described dead head and casting mold cavity disposal molding, eliminate prefabricated, the deposit of dead head and install, saved recruitment, avoid specific equipment and drop into, saved production place, it also avoid the waste of dead head prefabrication process Sand. In sand mold thermoforming process, in described dead head moulding process, waste heat can be made full use of, reduce production energy consumption. Described dead head and casting mold cavity integrated molding, dead head and casting mold cavity seamless link, it is ensured that gating system unimpeded, the defect such as avoid dead head floating.
Described dead head 5 profile and geometrical shape and the size thereof of die cavity design according to specific needs.
