Abstract

The utility model relates to a die casting device capable of solving a die casting sand hole problem. The die casting device capable of solving the die casting sand hole problem comprises a die, a feeding pipe and a plunger chip, wherein the feeding pipe is connected with the die, the plunger chip is arranged in the feeding pipe, and the die casting device further comprises an oxygen blowing-in pipe, and the oxygen blowing-in pipe is connected with the side wall of the feeding pipe. Compared with the prior art, the die casting device capable of solving the die casting sand hole problem has the advantages of being simple in structure, capable of enabling sand holes inside a product to be small, and the like.

Description

A kind of die casting equipment that solves die casting sand holes problem

Technical field

The utility model relates to a kind of die casting, especially relates to a kind of die casting equipment that solves die casting sand holes problem.

Background technology

The die-cast method be a kind of in the accurate mould with at a high speed and height inject by pressure aluminum solutions, produce the smoothly method of surperficial cast article of high accuracy.The die-cast method is widely utilized as the technological means that is best suited for volume production in the method for die-cast metal material product.But, because die casting method is within the extremely short time metallic solution to be filled in the core rod, the gas residue such as air in the core rod are at interiors of products, so there is following shortcoming in die casting method:

1) because gas is involved in internal flaw (sand holes) occurs in the product;

2) because gas expansion causes mesh (bubble), the phenomenons such as distortion are so can not get the heat treated high-temperature heat treatment of similar T6.

Produce high-intensity die casting so can't rely on the die-casting technique of low production cost.PF (imporosity) pressure casting method is for the weakness that overcomes die casting method in the past and produce.

Summary of the invention

The purpose of this utility model is exactly that a kind of simple in structure, die casting equipment that can make few the solved die casting sand holes problem of interiors of products sand holes is provided in order to overcome the defective that above-mentioned prior art exists.

The purpose of this utility model can be achieved through the following technical solutions:

A kind of die casting equipment that solves die casting sand holes problem, comprise mould, feed pipe and drift, described feed pipe is connected with mould, and described drift is arranged in the feed pipe, described die casting equipment comprises that also oxygen is blown into pipe, and described oxygen is blown into pipe and is connected on the feed pipe sidewall.

Described mould comprises counterdie and patrix movably, and described feed pipe is connected with patrix.

Be provided with charging aperture on the described feed pipe.

The drift of described drift for can in feed pipe, horizontally slipping.

Compared with prior art, the utlity model has following advantage:

1) simple in structure, easy to operate, low-cost, the satisfactory mechanical property of the utility model;

2) adopt the interiors of products defective (sand holes) of the utility model die casting few, be conducive to pressure-resistive products, the interiors of products gas flow is few, can realize T6 heat treatment.

Description of drawings

Fig. 1 is structural representation of the present utility model;

Fig. 2 is the product sectional schematic diagram of general die casting equipment die casting;

Fig. 3 is the product sectional schematic diagram of the utility model die casting equipment die casting.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Embodiment

As shown in Figure 1, a kind of die casting equipment that solves die casting sand holes problem, comprise that mould, feed pipe 4, oxygen are blown into pipe 3 and drift 5, described mould comprises counterdie 2 and patrix 1 movably, described feed pipe 4 is connected with patrix 1, described oxygen is blown into pipe and is connected to feed pipe near the side-walls of patrix 1, and described drift 5 is arranged in the feed pipe, and can horizontally slip in feed pipe.Also be provided with charging aperture on the described feed pipe 4.

The operation principle of above-mentioned die casting equipment is:

1) mobile patrix 1 is at the mould inside coating release agent;

2) closed die is blown into pipe 3 by oxygen and is blown into large oxygen in mould, and the gas in the mould is converted to oxygen, and the flow of large oxygen is 3～4m ³/ h;

3) inject solution by charging aperture and drift in mould, continue simultaneously to be blown into little oxygen in mould, solution and oxygen carry out oxidation reaction in mould, make mould inside become vacuum state, and the flow of little oxygen is 0.5～1m ³/ h;

4) until whole mould is full of solution, stop to be blown into of oxygen, the amount that is blown into oxygen is directly proportional with the volume of product;

5) mobile patrix 1 is opened mould, takes out product.

The utility model die casting equipment has following some effect: reduce bubble, can do T6 heat treatment and can weld, can produce low cost, the product of satisfactory mechanical property.

The utility model die casting equipment and general die casting equipment are compared, such as Fig. 2-shown in Figure 3, the lower relatively sand holes distribution of piston sectional anatomy exemplar the same terms (experiment product is product series, and place of incision is identical), the product of the utility model die casting equipment casting obviously is better than other.Because the interiors of products gas flow of the utility model casting is few, can realize T6 heat treatment in addition.
