Special production molds and injection molding equipment for automotive door harness seals

Abstract

The invention discloses a production die special for an automobile car door wiring harness sealing cover. The production die comprises an upper die, a lower die and a cavity. The lower die comprises a fixed die and a movable die. The movable die is located between the fixed die and the upper die. The fixed die and the upper die are female dies. The movable die comprises a die holder and a male die matched with the cavity. The male die comprises a fixed part and a movable part. The die holder is provided with a sliding groove for the movable part to slide. Positioning areas are arranged on the two end portions of the movable part and the two end portions of the fixed part. The die base is arranged outside the fixed die in a sleeving manner, and the die holder can move towards or away from the fixed die. The production die special for the automobile car door wiring harness sealing cover improves the strength of a connecting structure between a plastic clamp and the wiring harness sealing cover. The invention discloses an injection molding device with the die. By means of an upright form, a rotary disk is matched to improve the production efficiency of the automobile car door wiring harness sealing cover.

Description

technical field [0001] The invention relates to the technical field of injection molding equipment for auto parts, in particular to a special production mold and injection molding equipment for automobile door wire harness sealing sleeves. Background technique [0002] There are many signal wires arranged on the door of the car. In order to prevent damage to these signal wires during long-term car opening and closing and weather reasons, these signal wires are usually covered with wire harness seals for protection. [0003] The wire harness seals in the prior art have different shapes according to different models. A common example is a rubber sheath for wire harnesses for automobile doors disclosed by the announcement number CN201821052U, which includes sealing ends at both ends and corrugated ends in the middle Section, the middle part of the rubber sheath is set as a hollow for the passage of signal wires, the sealed ends at both ends are used to connect the door and the ...

[0005] Chinese Patent Publication No. CN203712975U discloses a rubber injection system for wire harness sheaths. This patent discloses a mold for producing harness sheaths, which can only shape the wire harness sheaths, that is to say, the rubber sheaths Design the corresponding injection mold according to the required shape, and form a rubber sheath through injection molding vulcanization and other processes, while the plastic clip is made of plastic material and has a certain rigidity. The plastic clip is also independently produced in advance, and then the plastic clip is covered again. On the rubber sheath, because the rubber sheath is made of rubber material, it is relatively soft. The connection between the plastic clip and the rubber sheath is not particularly stable, and it is easy to weaken the connection stability of the two during the long-term door opening action and cause separation. question
