Abstract
A novel die hot runner relates to the technical field of die hot runner. A main runner (2) is arranged in a main runner insert (1); a first sub-runner (4) is arrange in a spreader plate (3); a plurality of sub-runner inserts (5) are uniformly arranged below the spreader plate (3); a cavity plate (7) is arranged below the sub-runner inserts (5); one end of a second sub-runner (6) is connected to the first sub-runner (4), and the other end is connected to a cavity (8); and electric heating wires (9) are arranged in the main runner insert (1), the spreader plate (3) and the sub-runner inserts (5). Two sides of the runner are provided with electric heating wires, which can heat in advance before injection moulding, so as to reduce residual raw materials in the runner and increase fluidity of the raw materials.
Description
Technical field:
The present invention relates to the mold hot flow technical field, be specifically related to a kind of novel mold hot flow.
Background technology:
Mould is accounting for main status in modern industry, a lot of products all need mould molding, and mould can be produced in enormous quantities, reduce costs, a lot of plastic products all need to use mould molding, and use hot runner plastic injection mould in the majority, sprue and runner are arranged in general hot runner plastic injection mould, sprue and runner are when injection moulding, do not have the temperature of raw material high owing to just starting temperature, easily make the raw material mobility variation of sidewall, and when injection moulding finishes, the sidewall of runner has residual raw material, can affect the quality of moulding next time.
Summary of the invention:
The purpose of this invention is to provide a kind of novel mold hot flow, it is provided with electrical heating wire in the both sides of runner, can in advance runner be heated, and then carry out injection moulding, the residual of runner Raw can be reduced like this, and the mobility of raw material can be increased.
in order to solve the existing problem of background technology, the present invention is by the following technical solutions: it comprises sprue mold insert 1, sprue 2, flow distribution plate 3, the first runner 4, runner mold insert 5, the second runner 6, cavity plate 7 and die cavity 8, sprue 2 is arranged on the inside of sprue mold insert 1, flow distribution plate 3 is arranged on the bottom of sprue mold insert 1, the first runner 4 is arranged on the inside of flow distribution plate 3, several runner mold inserts 5 evenly are arranged on the bottom of flow distribution plate 3, the second runner 6 is arranged on the inside of runner mold insert 5, cavity plate 7 is arranged on the bottom of runner mold insert 5, several die cavities 8 are arranged on the inside of cavity plate 7, one end of the second runner 6 is connected with the first runner 4, its other end is connected with die cavity 8, described sprue mold insert 1, the inside of flow distribution plate 3 and runner mold insert 5 evenly is provided with electrical heating wire 9.
The inside of described sprue mold insert 1, flow distribution plate 3 and runner mold insert 5 is provided with temperature-detecting device 10.Can measure at any time internal temperature, with the temperature of raw material, be consistent.
The present invention has following beneficial effect: it is provided with electrical heating wire in the both sides of runner, can in advance runner be heated, and then carry out injection moulding, can reduce the residual of runner Raw like this, and can increase the mobility of raw material.
Description of drawings:
Fig. 1 is structural representation of the present invention.
The specific embodiment:
referring to Fig. 1, this specific embodiment by the following technical solutions: it comprises sprue mold insert 1, sprue 2, flow distribution plate 3, the first runner 4, runner mold insert 5, the second runner 6, cavity plate 7 and die cavity 8, sprue 2 is arranged on the inside of sprue mold insert 1, flow distribution plate 3 is arranged on the bottom of sprue mold insert 1, the first runner 4 is arranged on the inside of flow distribution plate 3, several runner mold inserts 5 evenly are arranged on the bottom of flow distribution plate 3, the second runner 6 is arranged on the inside of runner mold insert 5, cavity plate 7 is arranged on the bottom of runner mold insert 5, several die cavities 8 are arranged on the inside of cavity plate 7, one end of the second runner 6 is connected with the first runner 4, its other end is connected with die cavity 8, described sprue mold insert 1, the inside of flow distribution plate 3 and runner mold insert 5 evenly is provided with electrical heating wire 9.
The inside of described sprue mold insert 1, flow distribution plate 3 and runner mold insert 5 is provided with temperature-detecting device 10.Can measure at any time internal temperature, with the temperature of raw material, be consistent.
This specific embodiment is before injection moulding, heating wire is switched on, preheated mold, utilize temperature-detecting device to detect the temperature of preheating in the time of preheating, when temperature reaches the temperature of raw material, stopped heating, the raw material near the runner inboard just not there will be the phenomenon that causes poor fluidity because of temperature difference like this, and residual raw material also reduces relatively.
This specific embodiment is provided with electrical heating wire in the both sides of runner, can in advance runner be heated, and then carry out injection moulding, can reduce the residual of runner Raw like this, and can increase the mobility of raw material.
