Abstract

The utility model provides a low pressure casting gate choke tooling and comprises a handle, a bracket and choke plugs. The choke plugs are respectively fixed and connected below the bracket to correspond to the position of each casting gate and have the same shape with the casting gates; the bracket is connected with the handle to facilitate manual operation. The low pressure casting gate choke tooling integrates the choke plugs having the same shape with the casting gates to form an integral structure, and the structure is compact and favorable for manufacturing and using. A worker only needs to cover the tooling on the casting gates after taking out the casting, and clear the die cavity with compressed air to prevent the residual impurities such as fragmentary sands, aluminum scraps and the like in the cavity from entering into the casting gates so as to avoid waste of casting and quality reduction of liquid aluminum.

Description

A kind of low pressure casting cast gate stops up frock

Technical field

The utility model relates to the low-pressure casting system, and the casting system of the low pressure casting spare of core is particularly arranged.

Background technology

The mould of low-pressure casting system is all organized after casting is finished and will be cleared up broken sand, aluminium bits etc., usually after the workman takes out foundry goods is directly to clear up mould with compressed air, because the low-pressure casting system does not have cast gate to stop up frock, impurity such as the interior remaining broken sand of die cavity, aluminium bits are easy to be blown in the cast gate, a part is stayed in the cast gate, when casting once more, be back in the casting mold, the part foundry goods is scrapped with aluminium liquid; A part enters the maintenance stove by stalk, reduces the aluminium water quality, and then reduces casting quality.

Summary of the invention

The purpose of this utility model provides a kind of simple in structure, compact, easy to operate low pressure casting cast gate and stops up frock, and impurity reductions such as the interior remaining broken sand of solution die cavity, aluminium bits are back to aluminium liquid and make the problem that the part foundry goods is scrapped and the aluminium water quality reduces in the casting mold.

The technical solution of the utility model is as follows:

A kind of novel low pressure casting cast gate stops up frock, comprises handle, support and plug.The position of corresponding each cast gate is fixedly connected with plug respectively below described support, and described plug is consistent with gate shape; Be connected with handle on the described support, be convenient to workman's operation.

This low pressure casting cast gate stops up frock the plug identical with gate shape is gathered together simply, forms an overall structure, and compact conformation is beneficial to manufacturing, uses.The workman only needs this worker is covered on the cast gate after taking out foundry goods, and then with compressed air mold cavity is cleared up, and can prevent that just impurity such as broken sand remaining in the die cavity, aluminium bits from entering cast gate, avoids foundry goods to scrap and the reduction of aluminium water quality.

Fig. 1 is a vertical view of the present utility model;

Fig. 2 is the A-A profile of Fig. 1;

The specific embodiment

Referring to Fig. 1 and Fig. 2.This low pressure casting cast gate stops up frock and comprises handle 1, support 2 and plug 3.Plug 3 shapes, quantity are according to the shape and the quantity manufacturing of cast gate, and plug 3 is connected support 2 belows by bolt, and corresponding one by one with the position of each cast gate for it, as shown is 4 plugs.Handle 1 is rack-mount, and handle makes things convenient for the workman to operate.

When mould is opened, after foundry goods taken out, the workman was directly covered this frock on cast gate, with compressed air mold cavity is cleared up then, after cleaning out frock is taken off, and carries out next-step operation.

Claims

1. a low pressure casting cast gate stops up frock, it is characterized in that: described frock is made up of handle (1), support (2) and plug (3), position at corresponding each cast gate in described support (2) below is fixedly connected with plug (3) respectively, and described plug (3) is consistent with gate shape; Be connected with handle (1) on the described support.
