Abstract
The invention relates to a plastic mold. The plastic mold comprises a movable mold body and a fixed mold body. A core is arranged in the movable mold body. Small balls are arranged between the core and the movable mold body. The small balls are fixed through a fixing device which is fixed to the core through screws. A cavity and a cooling water pipe are arranged in the fixed mold body. A cooling medium flows in the cooling water pipe to cool high-temperature plastics in the cooling cavity. Two water storage devices are arranged at the two ends of the fixed mold body respectively. The cooling water pipe is connected with the water storage devices through water pipe connectors. According to the plastic mold, the high-temperature plastics can be rapidly cooled, so that no closing trace is caused in the position of a sprue of a plastic product; in addition, the friction between the core and the movable mold body can be effectively relieved; and the quality of the plastic product is improved.
Description
Technical field
The present invention relates to a kind of mould, particularly relate to a kind of plastic mould.
Background technology
Recently, along with the development of plastics industry, the range of application of plastic product constantly expands, and the ratio shared by plastic products also rapidly increases.Mould of plastics is a kind of built-up plastics mould shaping for extrusion molding, injection, compression moulding, blowing and low ratio foamed, and it mainly comprises dynamic model, cover half, and usual dynamic model is provided with core, and cover half is provided with die cavity.At present, the waste material of plasthetics at cast gate place and plasthetics not easily separated, very easily leave closed vestige at cast gate place, affect the quality of product and attractive in appearance.On the other hand, in process, the impact of the natural cause such as to be under pressure, between core and dynamic model, wearing and tearing can constantly increase, and affect the precision of plastic mould, and then affect quality and the glossiness of plastic products.
Because above-mentioned defect, the design people's actively in addition research and innovation, to founding a kind of plastic mould of new structure, makes it have more value in industry.
Summary of the invention
For solving the problems of the technologies described above, the object of this invention is to provide a kind of plastic mould, it can make high temperature plastic cement cool fast, thus makes plasthetics at cast gate place without closed vestige, and the friction that can effectively reduce between core and dynamic model, improve the quality of plasthetics.
Plastic mould of the present invention, comprise dynamic model and cover half, in described dynamic model, be provided with core, between described core and dynamic model, be provided with bead, be provided with die cavity and cooling water pipe in described cover half, in described cooling water pipe, have cooling medium to flow through the high temperature plastic cement cooled in described die cavity.
Further, be fixed by fixture between described bead.
Further, described fixture is fixed on described core.
Further, described fixture is fixed band.
Further, described fixed band is fixed by screws on described core.
Further, described cover half two ends are respectively provided with a water-storing device.
Further, described cooling water pipe is connected by water pipe head with described water-storing device.
Further, the material of described bead is stainless steel.
Further, described cooling medium is water or the kerosene of cooling.
Further, the material of described cooling water pipe is copper.
By such scheme, the present invention at least has the following advantages:
1, the cooling water pipe that arranges below die cavity of the present invention, cooling medium is had to flow through the high temperature plastic cement cooled in die cavity in cooling water pipe, so not only add film-cooled heat, and substantially reduce cool time, improve the cooling effectiveness of product largely, high temperature plastic cement can be made to cool fast, thus make plastic products at cast gate place without closed vestige.
2, the bead that arranges between core and dynamic model of the present invention, effectively reduces the friction between core and dynamic model, ensure that the precision of plastic mould, while raising plasthetics quality and glossiness, also extends this mold use life-span.
Above-mentioned explanation is only the general introduction of technical solution of the present invention, in order to better understand technological means of the present invention, and can be implemented according to the content of description, coordinates accompanying drawing to be described in detail as follows below with preferred embodiment of the present invention.
