Description

Die casting removes runner anchor clamps

Technical Field

The utility model relates to the technical field of part machining, in particular to a die casting gate removing clamp.

Background

In the die casting production of parts, die casting blanks usually need to be removed from the pouring gate, slag ladle and exhaust gas before the die casting blanks are transferred to the subsequent steps. The die-casting blank shown in fig. 1 comprises a die-casting part and a gate part, and the die-casting part is provided with a positioning hole which is convenient to position and install.

In actual production, the removal of the gate can be divided into: manual degating and mechanical degating. And manually removing the pouring gate, namely, knocking off the pouring gate by using a worker through a wood/hammer. However, the wall thickness of the die casting is thinner, and the problem of deformation of the die casting is extremely easy to cause when workers strike the pouring gate; and the thickness of the pouring gate is close to that of the die casting, and the die casting is easily damaged by manually removing the pouring gate, so that the problem of meat deficiency of the die casting is caused. Mechanical degating can be divided into mold degating and trimming mold degating. The processing cost of both mechanical degating processes is high.

Disclosure of Invention

In view of the above-mentioned drawbacks or shortcomings in the prior art, it is desirable to provide a die casting degating fixture which has a simple structure, is convenient to install, is easy and convenient to operate, has low processing cost, can avoid die casting deformation and meat deficiency, and ensures the processing quality of parts.

The utility model provides a die casting pouring gate removing clamp which comprises a lower clamp and an upper clamp; a profiling cavity is arranged between the lower clamp and the upper clamp; a first locating pin is arranged at the bottom in the profiling cavity; one end between lower anchor clamps and the last anchor clamps is rotated through coupling assembling and is connected, and the other end passes through fixed subassembly detachable fixed connection.

Further, the connecting assembly comprises a connecting groove arranged at one end of the lower clamp, a connecting block embedded in the connecting groove is fixedly arranged at one end of the upper clamp, and the connecting block is rotationally connected with the connecting groove through a shaft rod.

Further, the positioning and fixing assembly comprises a second positioning pin fixedly arranged on the top surface of the other end of the lower clamp, a positioning pin hole is formed in the bottom surface of the upper clamp corresponding to the second positioning pin, a pressing plate is arranged on one side of the second positioning pin, one end of the pressing plate is connected with the lower clamp through a locking bolt, and the other end of the pressing plate is pressed on the top surface of the upper clamp.

Further, the clearance between the profiling cavity and the die casting is smaller than 0.65mm.

Further, the lower clamp, the upper clamp, the connecting assembly and the positioning and fixing assembly are all made of stainless steel materials.

Compared with the prior art, the utility model has the beneficial effects that:

the clamp of the utility model consists of a lower clamp and an upper clamp. When the pouring gate removing treatment is carried out, the casting part of the casting blank is clamped and fixed through the upper clamp and the lower clamp, and the clamping protection is formed on the casting part. When workers knock off the pouring gate by using a wood/hammer, the problem of deformation of the casting piece is effectively avoided; and the fracture part of the casting blank is positioned on the pouring gate, so that the problem of meat deficiency of the die casting is effectively avoided, and the processing quality of the die casting is ensured. And after the pouring gate is knocked off, the residual pouring gate stubble breaking on the die casting is ground off. The consistency and the qualification rate of the degating of the die castings are greatly improved.

The fixture is simple in structure, convenient to install, simple and convenient to operate, and low in processing cost, and almost does not need additional maintenance on the premise of ensuring periodic purging of aluminum scraps of the fixture.
