The mechanism can better improve the energy consumption of the machine and reduce the radiation generated by the heat in the transfer.
Description
Technical Field
The utility model belongs to a plastic injection molding machine relates to a mechanism that heats plastics raw materials to melting to utilize the screw rod to extrude it.
Background
In order to melt the plastic, the barrel needs to be heated to a certain temperature so that the plastic can be heated and melted simultaneously in the advancing process.
Chinese patent application 201210278450.8 discloses a gas heating device for an injection molding machine, wherein a heat source is sent to a heat conduction chamber by a heat absorption fan through a heat transmission pipeline, and a screw cylinder is heated by the heat conduction chamber.
Chinese patent application 201510366508.8 discloses an extrusion device for injection molding, which utilizes a heating cylinder to heat a feeding cylinder through a heat conducting cylinder.
In the prior art, the cylinder is heated by gas or electric heating wires, and heat is transferred from the outside of the cylinder to the inside of the cylinder, so that energy is not only lost in the transfer, but also a large amount of heat is radiated to the outside, the ambient temperature is increased, and the working environment is deteriorated.
In addition, heating wires are used for heating, and the heating wires are installed outside a heating cylinder, which serves not only as a heat carrier but also as a fixing member for the heating wires, and the heating wires are usually wound around the heating cylinder.
Disclosure of Invention
The utility model aims at providing a plastics injection molding machine's extrusion mechanism, it is reformed transform to heating structure, is suitable for and adopts the quartz glass heating pipe as heating element, can improve the energy consumption of machine better and reduce the radiation of heat outside production in the transmission.
The purpose of the utility model is realized by the following scheme:
the utility model provides an extrusion mechanism of plastics injection molding machine, includes feed cylinder, screw rod and motor, is provided with feed inlet and discharge gate on the feed cylinder, and the screw rod setting is in the feed cylinder, drives the screw rod by the motor and rotates in the feed cylinder, and its characteristics are, and the feed cylinder distributes on being the annular section of thick bamboo wall of circle and be the cavity of cylindrical shape with axially parallel, and the feed cylinder both ends are provided with the support respectively, and the quartz glass heating pipe is located the cavity, and the quartz glass heating pipe both ends stretch out from the cavity, and two supports are connected with quartz glass heating pipe.
Therefore, the quartz glass heating tube can be fixed in the charging barrel through the bracket, and heat emitted by the quartz glass heating tube can be transmitted to the interior of the charging barrel through the wall of the charging barrel, so that the plastic is heated and melted.
Thus, a press is obtained in construction which can use a quartz glass heating tube as the heating element.
According to the plastic molding extruder obtained by the method, the heating element adopts the quartz glass heating pipe, and the heat is sent out from the middle of the wall of the charging barrel and is transferred to the inside of the charging barrel, so that the temperature in the charging barrel is increased more quickly, the loss of the heat is reduced, the improvement of the heat efficiency and the reduction of the heat radiation outside are facilitated, and the effects of energy conservation and emission reduction are achieved.
Preferably, in the above scheme, a heat insulation layer is installed on the outer side of the cylinder wall of the charging barrel. The heat insulation layer can further reduce the outward radiation of heat, so that the heat emitted by the quartz glass heating tube is better collected in the charging barrel, and the surrounding working environment is improved.
