Embodiment Construction

[0017] The present invention will be further described below in conjunction with specific drawings and embodiments.

[0018] Such as Figure 1-3 Shown: screw extruder 7, feeding port 8, machine head 9, die 10, tread 11, tread conveyor belt 12, tread outlet 13, the tread is discharged through the die plate, and the die plate is divided into It is an inner mouth type and an outer mouth type, and the inner mouth shape is fixed, and an electric heating tube is embedded inside. The outer opening plate is detachable and divided into upper and lower outer opening plates. The inner and outer mouth plates are separated, and it is difficult for the heat of the electric heating tube of the inner mouth plate to be completely transferred to the outer mouth plate.

[0019] Such as Figure 4-5 As shown, a tread plate heating device is fixed on one side of the machine head and can be opened and closed flexibly.

[0020] The tread is molded through a die plate, which is divided into an inn...

Abstract

The invention relates to a novel tread mouth-shaped plate heating device. The heating device is characterized in that a tread is molded through a mouth-shaped plate, the mouth-shaped plate is dividedinto an inner mouth-shaped plate and an outer mouth-shaped plate, the inner mouth-shaped plate is fixed, an electric heating pipe is embedded in the inner mouth-shaped plate, the outer mouth-shaped plate is detachable and is divided into an upper outer mouth-shaped plate and a lower outer mouth-shaped plate, and a steam nozzle capable of being closed is installed outside the mouth-shaped plate, after the mouth-shaped plate is installed, a steam nozzle is closed and fixed outside the mouth-shaped plate. The device is simple and convenient, the mouth-shaped plate can be heated to the needed temperature within a short time, waste such as bad return of the tread due to the low temperature of the mouth-shaped plate in the early stage of production is reduced, and the quality of parts is improved.

Description

technical field [0001] The invention relates to the technical field of tire tread component production, in particular to a tread mouth plate heating device. Background technique [0002] The molding of the tread is mainly determined by the mouth plate, which needs a certain temperature to ensure the stability of the tread molding, and the existing heating method mainly depends on the preheating of the outer mouth plate in the heating box and the inner heating of the inner mouth. The mouth plate is heated by electric heating tube. The preheating in the mouth-shaped heating box takes a long time, and the effect of frequent switching is limited. The power of the mouth plate electric heating tube is limited, and due to the gap between the inner and outer mouth plates, the heat conduction to the outer mouth plate is not enough. Especially in the early stage of production, the temperature of the mouth shape is not enough, which leads to bad edges of the tread. Contents of the ...
