Abstract
The invention discloses an injection mould which comprises a moving injection mould and a fixed injection mould corresponding to the moving injection mould, wherein the moving injection mould and the fixed injection mould are respectively provided with fixed plates; the moving injection mould and the fixed injection mould are square moulds, radiating grooves are respectively formed on four faces around the square moulds, a first cooling water pipe is connected to the back face of the moving injection mould, and a second cooling water pipe is arranged on the top of the fixed injection mould. Through the manner, the injection mould disclosed by the invention increases the surface areas of the moving injection mould and the fixed injection mould by virtue of the radiating grooves, so that the efficiency of air-cooling radiation is improved, temperature rise of the mould is effectively alleviated, the use level of cooling water is reduced, and the production cost is lowered.
Description
Technical field
The present invention relates to Design of Dies field, particularly relate to a kind of injection mold.
Background technology
The plastic part such as bottle cap, remote controller casing is all generally adopt injection mold to produce, and injection mold is made up of dynamic model and cover half two parts, and dynamic model is arranged on the moving die plate of injection (mo(u)lding) machine, and cover half is arranged on the fixed form of injection (mo(u)lding) machine.When injection moulding, dynamic model and cover half close and form running gate system and die cavity, and during die sinking, dynamic model is separated with cover half, then takes out plastic products.
Although the structure of mould may be ever-changing because plastics variety and performance, the shape of plastic products and the type of structure and injector etc. are different, basic structure is consistent.Injection mold is in continuous print process, and be injection molding material constantly heating, mold temperature rises, bad owing to dispelling the heat, and easily causes formed product slow, extends demould time, and product deforms problem in knockout course, causes and scraps.The method generally taked leads to cooling water in a mold to cool, comparatively large to the demand of cooling water, and constantly heated when cooling water circulation utilizes, and the efficiency repeatedly cooled is poor, needs to install large-scale cooling pond or tower in addition additional, and cost is high.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of injection mold, improves the performance of mould heat radiation, reduces cooling water amount.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: provide a kind of injection mold, comprise: injection moulding dynamic model and the injection moulding cover half corresponding with injection moulding dynamic model, described injection moulding dynamic model and injection moulding cover half are respectively arranged with fixed head, described injection moulding dynamic model and injection moulding cover half are respectively square module, four faces of described square module surrounding are respectively arranged with heat radiation groove, the back side of described injection moulding dynamic model is connected with the first cooling water pipe, and the top of described injection moulding cover half is provided with the second cooling water pipe.
In a preferred embodiment of the present invention, the front four edges of described injection moulding dynamic model is respectively arranged with contour localization block, described injection moulding cover half is provided with the groove corresponding with contour localization block.
In a preferred embodiment of the present invention, the back side of described injection moulding cover half is provided with injection molding material cast gate module.
In a preferred embodiment of the present invention, the below of described first cooling water pipe is provided with the first return pipe.
In a preferred embodiment of the present invention, the bottom of described injection moulding cover half is provided with second return pipe corresponding with the second cooling water pipe.
The invention has the beneficial effects as follows: a kind of injection mold that the present invention points out, increased the surface area of injection moulding dynamic model and injection moulding cover half by heat radiation groove, improve the efficiency of wind-cooling heat dissipating, effectively slow down the rising of mold temperature, reduce the consumption of cooling water, save production cost.
