Abstract
The invention relates to the field of dies, in particular to a plastic die used for producing plastic products. The plastic die comprises a die cavity and further comprises electric heaters evenly distributed on the outer side of the die cavity and a plurality of pipelines of female die inserts, wherein the pipelines are evenly distributed on the outer side of the die cavity. The pipelines are crossed to form a net shape, and the electric heaters are located in the pipelines. According to the plastic die, the pipelines which are crossed to form the net shape are arranged on the female die inserts on the outer side of the die cavity, the electric heaters are arranged in the pipelines for heating, the die cavity is heated on the periphery of the die cavity, heating is even, and the heating speed is high.
Description
Technical field
The present invention relates to mould applications, be specifically related to a kind of mould of plastics for the production of plastic product.
Background technology
For thermosetting plastics, such as solid silicone rubber or liquid thermosetting plastics, when using it to generate plastic product, plastic material need be put between mold cavity and punch and (namely form the region of plastic product), carrying out heating to plastic material makes it melt, and the melt in die cavity forms plastic product through pressurize, cooling, solidifying and setting.Heating heats solid silicone rubber or fluent material to molten state by modes such as the PULSE HEATING of soldering tip or heated at constant temperature, and PULSE HEATING costly, and heats uneven, and heated at constant temperature is comparatively slow, need consume the long period.
Summary of the invention
The object of the present invention is to provide more even, the firing rate mould of plastics faster of a kind of heating.
To achieve these goals, the technical solution adopted in the present invention is: mould of plastics, comprise mold cavity, it is characterized in that: also comprise the some pipelines being uniformly distributed in electric heater outside mold cavity, being uniformly distributed in the die plate insert outside mold cavity, some pipelines are interweaved and reticulate, described electric heater is positioned at pipeline, is also provided with heat-conducting medium in described pipeline.
The die plate insert of the present invention outside mold cavity is provided with the webbed pipeline of some intertextures, and some electric heaters are placed in pipeline, heat, and heat around mold cavity to mold cavity, and heating is comparatively even, and firing rate is very fast.
Accompanying drawing explanation
Fig. 1 is structure chart of the present invention;
Detailed description of the invention
Figure is the preferred embodiments of the present invention, and below in conjunction with accompanying drawing, the invention will be further described.
According to Fig. 1, mould of plastics, comprise mold cavity 1 (region for the formation of plastic product), it is characterized in that: also comprise the some pipelines 3 being uniformly distributed in electric heater 4 outside mold cavity 1, being uniformly distributed in the die plate insert 2 outside mold cavity 1, some pipelines 3 are interweaved and reticulate, described electric heater 4 is positioned at pipeline 3, is also provided with heat-conducting medium in described pipeline 3.In Fig. 1, section of tubing complete graph shows, section of tubing only represents with lines.
The die plate insert 2 of the present invention outside mold cavity 1 is provided with the webbed pipeline 3 of some intertextures, some electric heaters 4 are placed in pipeline 3, place water and heat in pipeline 3, therefore heat mold cavity 1 around mold cavity 1, heating is comparatively even, and firing rate is very fast.
