Description

Technical Field

[0001] The utility model belongs to the technical field of automobile steering wheel injection molding, and in particular relates to an automobile steering wheel mold with a changed original flow channel. Background Art

[0002] The steering wheel is a key component that converts the force applied by the driver to the edge of the steering wheel into torque and then transmits it to the steering shaft. The earliest steering wheels were made of metal, but now most steering wheels have a skeleton wrapped in a wrapping material, and the steering wheel skeleton is mostly made of zinc alloy or aluminum alloy. From an environmental protection perspective, the wrapping material can be made of EPP through a foaming machine, so when processing the steering wheel, a steering wheel mold is needed to process it so that the steering wheel can be processed and formed.

[0003] In the existing process of using the steering wheel mold, the material is poured into the interior of the semi-automatic steering wheel mold, and the material is processed into the required steering wheel in the cavity inside the steering wheel mold. However, since a waste bag is generally provided in the steering wheel mold, the provision of the waste bag can help optimize the production cost. By effectively utilizing the waste, the use of raw materials can be reduced. However, the existing waste bag provided in the steering wheel mold is generally a groove-type waste bag, and the groove-type waste bag may make it difficult to stack or combine the wastes tightly, resulting in larger gaps between the wastes, thereby reducing the utilization rate of the wastes, and ultimately causing material waste.
