Description

Casting mould of mistake proofing type, spark-out

Technical Field

The utility model relates to a casting mould technical field specifically is a casting mould of mistake proofing type, spark-out.

Background

The dislocation is very easy to produce because of the casting when producing plane products, and four sand child location are done to the sand child four corners to traditional way adoption sand child four corners, but because of the design of the location draft of sand child four corners and the characteristics of wet type clay sand self, sand child location is because of less and easily form the dead angle all around and fall sand and drop, the dislocation problem still does not get solved, runs out the fire and also can't solve moreover.

Patent document No. CN 204262285U discloses a mould for preventing mould from error box molding, which comprises an upper mould and a lower mould, wherein a mould assembling positioning groove is arranged in the upper mould corresponding to the parting line of the upper mould, and a mould assembling positioning boss is arranged in the lower mould corresponding to the parting line of the lower mould. The utility model discloses a guarantee that the sand box does not take place the wrong case during the mold assembling, not only be applicable to the boxless molding but also be applicable to the flaskless molding, cooperation that the sand mould can be accurate about during the on-the-spot operation mold assembling, the wrong case that arouses when having avoided equipment ageing to lead to the mold assembling has improved production efficiency moreover, has reduceed the rejection rate, has reduced manufacturing cost, has created good economic benefits for the company. However, this utility model when using wet type clay sand child location, still exist the location boss less and easily form the dead angle all around and fall the condition that the sand drops to cause the wrong type and the problem of running a fire still not to be solved.

Disclosure of Invention

In view of this, the utility model provides a to the not enough of prior art, the casting mould of mistake proofing type, the running fire that can solve mistake type and running fire problem that provides.

In order to solve the technical problem, the utility model discloses the technical scheme who takes is: a casting mould for preventing error type and fire running comprises an upper mould and a lower mould, wherein the parting surface of a product model of the upper mould is positioned below the parting surface of a first mould, the middle part of the mould is concave, the parting surface of a product model of the lower mould is positioned above the parting surface of a second mould, the middle part of the mould is convex, and the parting surfaces of the mould and the product model are connected by an annular curved surface; the upper die forms an upper die cavity on the upper sand mold, the lower die forms a lower die cavity on the lower sand mold, and the upper die cavity and the lower die cavity are in butt joint to form a die cavity for pouring a product casting.

Furthermore, the parting surface of the product model is sealed in a cavity formed by butting the upper cavity and the lower cavity to form a pouring product casting.

Further, the mould die joint the product model die joint with curved surface connecting portion are with circular arc transitional coupling, set up on the product model die joint the model and the gating system of product.

Furthermore, the curved surface and the parting surface of the product model form a certain drawing angle and surround the product model for a circle.

The further setting of drawing die angle is according to the distance and the setting of product model die joint and mould die joint distance, and the angle is little when the distance is near, and the angle is big when the distance is far away.

Furthermore, the product model parting surface and the curved surface circumference of the mould parting surface are connected to form a polygon, and the arc at the corner is transited.

Compared with the prior art, the beneficial effects of the utility model are as follows:

1. the utility model discloses prevent casting mould of type, running fire adopts and sets up the draft angle at product model circumference, and joggle area and intensity when the sand mould that has increased upper and lower model preparation is closed from top to bottom have ensured the precision of upper and lower die cavity butt joint, make it difficult to produce the type by mistake.

2. The utility model discloses the casting mould of mistake proofing type, running fire adopts the die joint setting that will go up mould product model to set up under the mould die joint, and the die joint setting of bed die product model is the design on the mould die joint, makes the upper and lower sand mould that upper and lower mould formed to the joint type after, and the die joint of product model is sealed in the sand mould, and at foundry goods pouring in-process, the effectual pouring that has prevented runs fire (the product die joint runs indisputable) problem.

3. The utility model discloses this kind of design of casting mould of mistake proofing type, running fire not only is applicable to no case molding technique, is applicable to case molding technique simultaneously, can both be fine play the mistake proofing type and prevent the problem of running fire.
