Abstract

The utility model relates to an austenite-bainite grinding ball forming mold, in particular to a forming mold of austenite-bainite grinding balls with diameters of 200mm. The forming mold comprises an upper mold and a lower mold, wherein the upper mold is provided with four upper hemispherical cavities and a pouring port, the upper hemispherical cavities are uniformly distributed on a concentric circle by taking the center of the pouring port as a circle center; the lower mold is provided with four lower hemispherical cavities, a thermal insulating blind riser and an ingate; the lower hemispherical cavities are uniformly distributed on a concentric circle by taking the center of the thermal insulating blind riser as a circle center, each lower cavity is connected with the thermal insulating blind riser by the ingate, and when the upper mold and the lower mold are closed, each upper hemispherical cavity and the lower hemispherical cavity, which are corresponding in position, form a forming cavity of the grinding ball. The forming mold has the beneficial effects of having a simple structure, meeting the production quality of the grinding balls, increasing the production quantity and improving the production efficiency.

Description

A kind of mould of shellfish abrading-ball difficult to understand

Technical field

The utility model relates to a kind of mould of shellfish abrading-ball difficult to understand, and relating in particular to a kind of diameter is the mould of the shellfish abrading-ball difficult to understand of 200mm.

Background technology

The production technology of cast grinding ball in current wear-resisting industry, most forms with manual or simple and easy foundry production line, use the mode of this die casting abrading-ball to have the remarkable defects such as production efficiency is low, per capita output is extremely low, production cost is high, labor strength is large, these defects make the various forms mould of the cast grinding ball that adopts in current industry cannot adapt to the manufacturing requirements of shellfish abrading-ball difficult to understand.

Utility model content

Technical problem to be solved in the utility model is to provide a kind of mould of shellfish abrading-ball difficult to understand, has overcome the low defect of production efficiency in abrading-ball production process.

The technical scheme that the utility model solves the problems of the technologies described above is as follows: a kind of mould of shellfish abrading-ball difficult to understand, comprise patrix, counterdie, described patrix is provided with four hemispheric upper impression, cast port, described upper impression is evenly distributed on center taking described cast port on the concentric circles in the center of circle, described counterdie is provided with four hemispheric lower impressions, insulation blind riser, ingate, described lower impressions is evenly distributed on center taking described insulation blind riser on the concentric circles in the center of circle, between described each lower impressions and described insulation blind riser, be connected by described ingate, when described patrix and described counterdie matched moulds, described each hemispheric upper impression forms the moulding die cavity of abrading-ball together with a position hemispheric lower impressions corresponding to it.

The diameter of the moulding die cavity of the abrading-ball further, forming together with the hemispheric upper impression described hemispheric lower impressions corresponding with it with position described in each is 200mm.

The beneficial effects of the utility model are: simple in structure, the quality of production that meets abrading-ball has improved production quantity simultaneously, has improved production efficiency.

Brief description of the drawings

Fig. 1 is the structural representation of the mould of shellfish abrading-ball difficult to understand of the present utility model;

Fig. 2 is the structural representation of the mould counterdie of shellfish abrading-ball difficult to understand of the present utility model.

In accompanying drawing, the list of parts of each label representative is as follows:

1, patrix, 2, counterdie, 3, upper impression, 4, lower impressions, 5, cast port, 6, ingate, 7, insulation blind riser.

Detailed description of the invention

Below in conjunction with accompanying drawing, principle of the present utility model and feature are described, example, only for explaining the utility model, is not intended to limit scope of the present utility model.

As shown in Figure 1 and Figure 2, the mould of the utility model shellfish abrading-ball difficult to understand comprises patrix 1, counterdie 2, described patrix 1 is provided with four hemispheric upper impression 3, cast port 5 for pouring molten iron, the cast center of port 5 and the center superposition of patrix 1, cast port 5 penetrates on the concentric circles that center that 1, four hemispheric upper impression 3 of patrix is evenly distributed on to pour into a mould port 5 is the center of circle.Described counterdie 2 is provided with four hemispheric lower impressions 4, insulation blind riser 7, ingate 6, the center superposition of the center of insulation blind riser 7 and counterdie 2, four hemispheric lower impressions 4 are evenly distributed on center taking described insulation blind riser 7 on the concentric circles in the center of circle, each hemispheric upper impression 3 forms the moulding die cavity of shellfish abrading-ball difficult to understand together with a position hemispheric lower impressions 4 corresponding to it, passes through ingate 6 UNICOMs between each lower impressions 4 and insulation blind riser 7.

In the time of patrix 1 and counterdie 2 matched moulds, the hemispheric upper impression 3 of on patrix 1 four and four hemispheric lower impressions 4 on counterdie 2 form the complete moulding die cavity of shellfish abrading-ball difficult to understand.UNICOM between insulation blind riser 7 on cast port 5 and counterdie 2 on patrix 1, molten iron is flowed in corresponding lower impressions 3 by each ingate 6 after flowing in insulation blind riser 7 by cast port 5 again.Insulation blind riser 7 is longer than the molten metal setting time in common blind riser, and feeding is effective, and insulation blind riser 7 adopts spherical feeder can reduce the impulse force of molten metal, ensures the Forming Quality of abrading-ball.The diameter of the complete die cavity of the shellfish abrading-ball difficult to understand that each upper impression 3 is combined to form with corresponding lower impressions 4 is 200mm.

Its course of work is: by patrix 1 and counterdie 2 matched moulds, after matched moulds, molten metal is poured in mould from cast port 5, molten metal flow in the insulation blind riser 7 in counterdie 2 by cast port, molten metal in insulation blind riser 7 flows in each lower impressions 4 by ingate 6 again, lower impressions 4 and upper impression 3 UNICOMs, the full lower impressions 4 of molten metal punching and upper impression 3, just form shellfish abrading-ball difficult to understand after molten metal is cooling.

The foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle, any amendment of doing, be equal to replacement, improvement etc., within all should being included in protection domain of the present utility model.
