Abstract
The invention discloses a thermosetting plastic forming die. The thermosetting plastic forming die comprises a terrace die (1) and a die (2), wherein a cavity for accommodating plastic products is formed after stacking the inner side of the terrace die (1) and the inner side of the die (2), a discal first electrical heating part (3) is fixedly arranged on the outer side of the terrace die (1), and a discal second electrical heating part (4) is fixedly arranged on the outer side of the die (2). A first heating plate (9) is arranged inside the electrical heating part (3), a second heating plate (10) is arranged inside the second electrical heating part (4), a first thermal baffle (5) is arranged on the outer side of the heating plate (9), and a second thermal baffle (6) is arranged on the outer side of the second heating plate (10). Strip-shaped heating pipes are arranged discal electrical heating pipes, and therefore the die can be heated continuously and constantly, all parts of the die are heated evenly, the defects of rough selvedges are generated in the plastic products caused by temperature influence, the plastic products are incomplete, surfaces of the plastic products are rough, and the like are avoided, and therefore quality of the plastic products is guaranteed.
Description
Technical field
The present invention relates to a kind of Machining Technology field, specifically a kind of thermosetting plastic moulding die.
Background technology
Plastic products generally adopt mould molding to produce in enormous quantities, after melting state in the plastic warp hot mastication, inject the die cavity cooling forming of mould.But because adopting metal material, makes by mould, its rapid heat dissipation, and the plastics that flow in die cavity are very fast cooling, easily cause the defectives such as plastic products are imperfect or rough.For the problems referred to above, the mode of steam, Re Bo, hot water heating of having released on market is to the injection molding material mold heated, thereby mold temperature is controlled in required temperature range.But above-mentioned a few class mode of heatings need to preheat these media of steam, oil and water, so the auxiliary equipment that needs is more, cost is higher; This three classes mode of heating, because all pass through the interior dielectric heating of pipeline, if each section temperature of the long pipeline of pipeline is inconsistent, cause being heated of mould inhomogeneous in addition, causes plastic products to have defective.
Summary of the invention
In order to overcome defects, the invention provides a kind of thermosetting plastic moulding die.
Technical scheme of the present invention is achieved in that a kind of thermosetting plastic moulding die, comprise punch (1) and die (2), after stacking, the inboard and die (2) of described punch (1) inboard has the cavity that holds plastic products, be installed with the electric heating part one (3) of plate-like outside its described punch (1), the outside of described die (2) is installed with the electric heating part two (4) of plate-like.
Establish heating plate one (9) in described electric heating part one (3), establish heating plate two (10) in described electric heating part two (4).
Described heating plate one (9) outside is provided with thermal insulation board one (5).
Described heating plate two (10) outsides are provided with thermal insulation board two (6).
The invention has the beneficial effects as follows: the electric heating tube of the heating tube of strip being arranged to plate-like, thereby make mould can continue constant being heated, the mould each several part is heated evenly, avoid plastic products to produce the defectives such as burr, goods are imperfect, rough because of the impact of mold temperature, thereby guarantee the quality of plastic products.
Description of drawings
Fig. 1 is the structural representation of thermosetting plastic moulding die of the present invention.
The specific embodiment
As shown in Figure 1, a kind of thermosetting plastic moulding die, comprise punch 1 and die 2, after stacking, the inboard and die of described punch 12 inboards have the cavity that holds plastic products, its described punch 1 outside is installed with the electric heating part 1 of plate-like, and the outside of described die 2 is installed with the electric heating part 24 of plate-like.Establish heating plate 1 in described electric heating part 1, establish heating plate 2 10 in described electric heating part 24.Described heating plate one 9 outsides are provided with thermal insulation board 1.Described heating plate 2 10 outsides are provided with thermal insulation board 26.
The above; only be the better specific embodiment of the present invention; but protection scope of the present invention is not limited to this; anyly be familiar with those skilled in the art in the technical scope that the present invention discloses; be equal to replacement or changed according to technical scheme of the present invention and inventive concept thereof, within all should being encompassed in protection scope of the present invention.
