Problems solved by technology

[0003] Traditionally, when the sunshade is manufactured, the injection molding process is used. In the injection molding process, the molten plastic enters the gate through the hot runner, and then enters the injection cavity through the gate, so that the cover body is formed. Generally, the gate used is U-shaped gate, the surface of the car sunshade made by this method has weld lines and the molding speed is very slow, the production efficiency is not high, which seriously affects the normal production of the enterprise, and the use effect of the sunshade is not good.

Embodiment Construction

[0019] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples, which are only used to explain the present invention, and do not limit the protection scope of the present invention.

[0020] The present embodiment provides the molding process of the automobile sunshade, which is carried out according to the following specific steps:

[0021] The first step: raw material drying, select polycarbonate as raw material, put it into the dryer for drying operation;

[0022] The second step: injection molding, put the raw materials into the injection molding machine, through the six steps of mold clamping, mold opening, injection, pressure holding, material storage and injection seat, the raw materials are in the shape of a cover body, which is adopted in the process of overall injection molding The gate is a long straight gate. The molten raw material enters the gate through the hot ru...

Abstract

Provided is molding technology of a car sun shade. The technology comprises following steps: drying raw material; performing injection molding operation; sawing a cast gate; trimming; mesh opening; and packaging into a warehouse. During injection molding, an elongated cast gate is adopted between a hot runner and an injection mold cavity for fusing plastics and conveying. Such operation enables the surface of the car sun shade without any fusing trace. The molding speed of the sun shade is increased by more than 10%. The molding technology of the car sun shade has following beneficial effects: production efficiency is obviously increased; and usage effect is also good after the sun shade is used in the later period.

Description

technical field [0001] The invention relates to the field of automobile equipment manufacturing, in particular to an automobile sunshade forming process. Background technique [0002] With the continuous improvement of people's material living conditions, automobiles have become the main tool of modern transportation. Since cars are mostly used during the day with sufficient sunlight, the light is very harmful to the driver's body and eyes, which affects the driving safety of the car to a certain extent. Especially in summer, when the car stays in the sun for a long time and is in a state of exposure, it will cause great damage to the outer surface and interior of the car. Too much heat, and there is an explosion hazard. A car with good performance is exposed to the sun for a long time, and the temperature inside the car is too high, which brings great discomfort to the driver and passengers when they get on the car. Therefore, the sun visor has a great prospect in the ma...
