Abstract

The invention relates to a hot runner injection mold for a door check. The hot runner injection mold comprises a fixed mold and a moving mold, wherein a fixed mold plate and a front mold core, which is fixedly arranged on the fixed mold plate, are arranged in the fixed mold; a moving clamp plate, a support block, a moving mold plate and a rear mold core, which is arranged on the moving mold plate,are arranged in the moving mold; a cavity is formed by the front mold core and the rear mold core; the fixed mold comprises a raw material interface and a hot runner; a heating unit is arranged on the outer wall of the hot runner; the front mold core is provided with a feeding port and a gas outlet; the feeding port is connected with the hot runner; and an ejection unit is arranged in the movingmold and used for demolding. Compared with the prior art, the hot runner injection mold provided by the invention has the advantages that through the hot runner, condensing materials are avoided, or only a small condensing material handle is needed; cold runner sprue materials are basically eliminated, so that recycling is avoided; and therefore, the cost can be greatly reduced, especially for costly plastic products which cannot be processed through recycled materials.

Description

technical field [0001] The invention relates to the technical field of automobile production, in particular to a hot runner injection mold for a door limit arm. Background technique [0002] The door limit arm, that is, the door opening limiter (Door check), is used to limit the degree of opening of the door. On the one hand, it can limit the maximum opening of the door to prevent the door from being opened too much. On the other hand, it can keep the door open when needed. For example, when the car is parked on a slope or the wind is blowing, the door will not automatically open. close. The common door opening limiter is a separate drawstring type limiter, and some limiters are integrated with the door hinge, and usually have the function of limiting when the door is fully opened and half opened. [0003] The existing production method of the door stop arm is injection molding production, that is, the raw material (generally resin material) is melted and injected into the...
