Abstract
The invention relates to the field of molds, in particular to a plastic mold for manufacturing plastic products. The plastic mold comprises a mold cavity, and is characterized in that the plastic mold also comprises electric heaters uniformly distributed outside the mold cavity, and multiple pipelines with concave mold inserts uniformly distributed outside the mold cavity; the multiple pipelines mutually interweave into a network; and the electric heaters are located in the pipelines. The plastic mold disclosed by the invention is provided with multiple mutually interweaved pipelines inserted on the concave mold outside the mold cavity, and the multiple electric heaters in the pipelines for heating, and heats the mold cavity at the periphery of the mold cavity with uniform heating and quick heating speed.
Description
Technical field
The present invention relates to mould applications, be specifically related to a kind of mould of plastics that is used to produce plastic product.
Background technology
For thermosetting plastics; Such as solid state si rubber or liquid thermosetting plastics; When using it to generate plastic product; Need put into plastic material between mold cavity and the punch and (promptly form the zone of plastic product), plastic material are heated make its fusing, and the melt in the die cavity forms plastic product through pressurize, cooling, solidifying and setting.Heating is to heat solid state si rubber or fluent material to molten state through modes such as the PULSE HEATING of soldering tip or heated at constant temperature, and PULSE HEATING is comparatively expensive, and heats inhomogeneously, and heated at constant temperature is slower, needs to consume the long period.
Summary of the invention
The object of the present invention is to provide that a kind of heating is more even, firing rate mould of plastics faster.
To achieve these goals; The technical scheme that the present invention adopted is: mould of plastics; Comprise mold cavity; It is characterized in that: also comprise the electric heater that is uniformly distributed in the mold cavity outside, the plurality of conduits that is uniformly distributed in the die plate insert in the mold cavity outside, plurality of conduits is interweaved and reticulates, and described electric heater is positioned at pipeline.
The present invention is provided with some webbed pipelines that interweave at the die plate insert in the mold cavity outside, and some electric heaters place pipeline, heats, and around mold cavity, mold cavity is heated, and heats comparatively evenly, and firing rate is very fast.
Description of drawings
Fig. 1 is a structure chart of the present invention;
Wherein, 1 mold cavity, 2 die plate inserts, 3 pipelines, 4 electric heaters.
The specific embodiment
Figure is the preferred embodiments of the present invention, below in conjunction with accompanying drawing the present invention is further described.
According to Fig. 1; Mould of plastics; Comprise mold cavity 1 (being used to form the zone of plastic product); It is characterized in that: also comprise the electric heater 4 that is uniformly distributed in mold cavity 1 outside, the plurality of conduits 3 that is uniformly distributed in the die plate insert 2 in mold cavity 1 outside, plurality of conduits 3 is interweaved and reticulates, and described electric heater 4 is positioned at pipeline 3.The section of tubing complete graph shows among Fig. 1, and section of tubing is only represented with lines.
The die plate insert 2 of the present invention in mold cavity 1 outside is provided with some webbed pipelines 3 that interweave; Some electric heaters 4 place pipeline 3, place water in the pipeline 3 and heat, and therefore around mold cavity 1, mold cavity 1 are heated; Heat comparatively evenly, firing rate is very fast.
The foregoing description does not limit the present invention in any form, and all employings are equal to the technical scheme that mode obtained of replacement or equivalent transformation, all drop on protection scope of the present invention.
