Problems solved by technology
The bracket is mainly composed of a hinge 11 and a plastic body 12, wherein the plastic body 12 is an integral plate structure, which makes the product consume more raw materials; because the thickness of each plate is not the same, the product is different when used. Due to the difference in force, it is easy to deform and cause damage to the bracket; and the product has a large molding surface, and the product shrinks severely during the molding process, so the dimensional accuracy of the product positioning surface cannot be guaranteed during injection molding
According to the structural characteristics of the bracket, the molding of the bracket adopts the gas-assisted molding process. The molding process has a long molding cycle. It takes nearly 30 minutes from the start of injection molding to the final molding and cooling of the product. The production efficiency is low and the product manufacturing cost is high.

Embodiment Construction
[0010] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
[0011] Such as figure 2 with 3 Shown is a lightweight structural plastic bracket, including a bracket body 2 and a bracket hinge 1. The bracket body 2 is connected to the bracket hinge 1. The bracket body 2 is a frame structure, and a plurality of reinforcing ribs 3 are connected to the bracket body 2. The reinforcing ribs 3 are connected between the frame of the bracket body 2 to strengthen the structural strength of the bracket body 2. The reinforcing ribs can adopt a combination of horizontal ribs, vertical ribs, circular ribs and various other forms to reduce the consumption of raw materials. The purpose of increasing the strength of the product structure.
[0012] The bracket body 1 of the plastic bracket adopts the structure of the frame and the reinforcing ribs 3, which reduces the injection molding area, so that the accuracy of the posit...

The invention relates to a plastic support with a light structure. The plastic support comprises a support body and a support hinge, the support body is connected with the support hinge, the support body is in a frame structure, and a plurality of reinforcing ribs are arranged on the support body. As the structure is used, the molding surface of the plastic support is decreased greatly, and the accuracy of a product positioning surface is easy to be guaranteed during injection molding; and material thickness at various positions is uniform during molding of the support body and the reinforcing ribs, stresses of the support are uniform during a usage process, the usage performance of the product is enhanced, and material consumption needed by product molding is reduced greatly simultaneously.
Description
Technical field [0001] The invention relates to an automobile plastic support, in particular to a plastic support optimized and designed with a lightweight structure. Background technique [0002] A large number of plastic parts are used in automobile production, which mainly play a role in decorating, supporting or protecting the electrical components in the car. figure 1 Shown is the central bottom chute bracket on the car, which is installed under the rear door to protect the wiring harness of the car circuit. The bracket is mainly composed of a hinge 11 and a plastic body 12. The plastic body 12 is an integral plate structure. With this structure, the product consumes a lot of raw materials; the thickness of each plate is different, resulting in different parts of the product during use. Due to the difference in force, it is easy to deform and cause damage to the bracket; and the product has a large molding surface, and the product shrinks severely during the molding process,...
