Description

One-mold multi-cavity die-casting mold runner

technical field

The utility model relates to the technical field of moulds, in particular to a multi-cavity die-casting flow channel of a mold. the

Background technique

The runner used by the general mold is that the molten alloy is transferred from the sprue to the runner and then enters the product cavity through the ingate. If the mold has a multi-cavity structure, a large die-casting machine must be used because the mold is large. However, because the pressure of a large die-casting machine is usually relatively high, the cavity of a small product is easily damaged, which affects the service life of the entire set of molds. the

Contents of the invention

In order to overcome the above-mentioned problems in the prior art, the purpose of this utility model is to provide a simple, practical, versatile, and reliable performance of a multi-cavity die-casting mold flow channel. the

The technical solution adopted by the utility model for solving the problem is: a flow channel of a multi-cavity die-casting mold, including a sprue, a sprue, a runner, a transition runner and an ingate, and the direct sprue The channel is semicircular with an opening to the left, and its upper port is connected to the pump nozzle, and its lower port is connected with the horizontal runner. The lower surface of the runner is connected with a transition runner, and the lower end of the transition runner is provided with a Ingate. the

Compared with the prior art, the utility model has the beneficial effects that: due to the use of the semicircular sprue, it forms an arc-shaped buffer zone, which can relieve the pressure of the alloy on the mold cavity during die-casting, and solve the problem of When a variety of different products are molded on the set of molds, the surface of small products is easy to be eroded due to excessive pressure on the cavity, which effectively improves the service life of the die-casting mold and ensures that each product has better pressure. The utility model has the advantages of simple structure, ingenious design, simple and practical, strong versatility, reliable performance and wide market value. the

Description of drawings

Accompanying drawing 1 is the structural representation of the utility model. the

The labels in the figure are: (1) large product, (2) small product, (3) nozzle, (4) sprue, (5) runner, (6) transition runner, (7) Ingate, (8) buffer zone. the

Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to accompanying drawing 1, a kind of one mold multi-cavity die-casting mold runner of the present utility model comprises nozzle 3, sprue 4, runner 5, transition runner 6 and ingate 7, and described direct sprue The channel 4 is semicircular with opening to the left, and its upper port is connected to the pump nozzle 3, and its lower port is connected with the laterally arranged runner 5. The lower surface of the runner 5 is connected with a transition runner 6, and the transition runner 6 The lower end of the road is provided with an ingate 7. the

The utility model adopts the structure design of the flow channel with a buffer zone 8 to replace the existing straight flushing flow channel, effectively reducing the pressure of the cavity, protecting the cavity of the small product 2 from being easily eroded, effectively prolonging the practical life of the mold, and improving production. Efficiency, and has the advantages of strong versatility, reliable structure, etc., and then achieve the design purpose. the

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any skilled person who is familiar with this profession may use the technical content disclosed above to change or modify it into an equivalent change, etc. However, any simple modifications, equivalent changes and modifications made to the above embodiments according to the technical essence of the utility model without departing from the technical solution of the utility model still belong to the scope of the technical solution of the utility model. the
