Description

A metal hammer mold

technical field

The utility model relates to the technical field of hammer head casting, in particular to a metal type hammer head mould.

Background technique

Existing hammer head production technology all needs to adopt wooden model sand mold or foam mold sand mold molding, carries out molten iron pouring to form hammer head casting again. The sand box or model can only be used once, and each product needs to be repeatedly mold-made or sand-box-made. There is a lot of duplication of labor, and it needs mold making, sand mill, sand mixer, sand box forming, etc. Mechanical equipment, casting auxiliary materials and multiple processes can only be completed, the quality fluctuates greatly, the output is low, the labor intensity of workers is high, the amount of auxiliary materials (foundry sand, foam, etc.) pollutes the environment, and the production cost is high.

Utility model content

The utility model mainly solves the technical problems existing in the prior art, thereby providing a metal hammer head mold with long service life, reusability and low labor intensity.

The above-mentioned technical problems of the utility model are mainly solved by the following technical solutions:

The metal type hammer head mold of the present utility model is composed of the same two mold bodies. The mold body is made of metal and includes two hammer head cavities arranged symmetrically. The upper parts of the two hammer head cavities A sprue communicates with each other, and a straight sprue is provided between the two hammerhead cavities, and the sprue communicates with the inrunner.

Further, the mold body is provided with a plurality of positioning holes and locking holes, and the two mold bodies are joined together through positioning pins and screws respectively passing through the positioning holes and locking holes.

Further, the number of the positioning holes and the locking holes are four respectively, and they are symmetrically distributed on the left and right sides of the mold body.

Further, the material of the mold body is cast iron or cast steel.

Compared with the prior art, the utility model has the advantages that: the metal-type hammer head mold is made of metal, and is processed and formed by machining and casting at one time, and no repeated mold making or sand box making is required. Using casting auxiliary materials (casting sand, foam materials, etc.), the mold can be used more than thousands of times, with a long service life, saving labor and time, and greatly reducing the labor intensity of workers.

Explanation of reference numerals: 1. Die body, 2. Hammer head cavity, 3. Inner runner, 4. Sprue, 5. Positioning hole, 6. Locking hole.

Detailed ways

The preferred embodiments of the utility model will be described in detail below in conjunction with the accompanying drawings, so that the advantages and features of the utility model can be more easily understood by those skilled in the art, so as to make a clearer definition of the protection scope of the utility model.

Referring to shown in Fig. 1-2, metal mold of the present utility model, this mold is spliced by identical two mold bodies 1, and mold body 1 is made of metal, and this metal is preferably gray iron or cast steel. The mold body 1 includes two hammerhead cavities 2 arranged symmetrically. The size of the cavity 2 varies with the size of different types of hammerheads. Specifically, the upper parts of the two hammerhead cavities 2 pass through an ingate 3 They communicate with each other, and there is also a straight runner 4 between the two hammerhead cavities 2, and the straight runner 4 communicates with the inner runner 3. The two hammerhead cavities 2 are simultaneously poured through the sprue 4, which improves the working efficiency.

In the utility model, the demoulding slope of the hammer head mold is 3-5 degrees, and the mold body of the mold is provided with a plurality of positioning holes 5 and locking holes 6, and the two mold bodies 1 are separated by positioning pins and screws. Pass through the positioning hole 5 and the locking hole 6 for splicing. Preferably, there are four positioning holes 5 and four locking holes 6, which are symmetrically distributed on the left and right sides of the mold body 1 .

In summary, the utility model has the following advantages:

1) The metal mold of the present utility model can be formed by one-time machining and casting.

2) No longer use casting auxiliary materials (casting sand, foam materials, etc.), which reduces the use of auxiliary equipment and materials, protects the environment, and reduces the consumption of resources. It is a green and environmentally friendly production technology.

3) There is no need for mold making, sand grinding, sand mixer, sand box molding and other processes, which reduces the production process and greatly reduces the labor intensity of workers.

4) The mold can be used more than thousands of times and has a long service life.

5) Technically and economically: (1) The mechanical properties of castings produced by metal molds are higher than those of sand castings. For the same alloy, the tensile strength can be increased by about 25% on average, and the yield strength can be increased by about 20% on average; (2) The precision and surface finish of the casting are higher than that of the sand casting, and the quality and size are stable; (3) The process of the casting is harvested High efficiency, reduced liquid metal consumption, generally can save 15-30%; (4) No sand or less sand is used, generally 80-100% of molding materials can be saved; in addition, the production efficiency of metal mold casting is high; The causes of defects are reduced; the process is simple, and it is easy to realize mechanization and automation.

The above is only a specific embodiment of the utility model, but the scope of protection of the utility model is not limited thereto, and any change or replacement that is not thought of through creative work should be covered within the scope of protection of the utility model . Therefore, the protection scope of the present utility model should be determined by the protection scope defined in the claims.
