A kind of injection molding device and injection molding method for automobile lightweight anti-collision protection bar

Abstract

The invention discloses an automobile light-weight anticollision protection bumper injection molding device and an injection molding method thereof, and relates to the technical field of an injectionmolding device, in particular to an automobile light-weight anticollision protection bumper injection molding device. The automobile light-weight anticollision protection bumper injection molding device comprises a fixed base plate provided with a fixed module and a movable module; an injection molding groove is formed inside each of the fixed module and the movable module; the fixed module is fixedly arranged at the right side of the top of the fixed base plate; a hollow cavity is formed inside the fixed base plate; the side wall of the hollow cavity is fixedly connected with a sliding rod; the outer part of the sliding rod is glidingly connected with a sliding plate. The automobile light-weight anticollision protection bumper injection molding device and the injection molding method havethe advantages that through the matched use of a pressure pump, a position limiting sleeve plate, a bearing pipe, a sheathing pipe and a regulating device, an injection molding element injected and molded by the device can be ejected out under the effect of the pressure pump; the condition that the existing injection molding device uses an ejector pin for ejecting out the injection molding element, so that the injection molding element can be easily damaged and damaged through ejecting is avoided; the device mold stripping convenience is improved.

Description

technical field [0001] The invention relates to the technical field of injection molding devices, in particular to an injection molding device and an injection molding method for a lightweight bumper of an automobile. Background technique [0002] The car bumper is the bumper, which is a safety device that absorbs and slows down the external impact and protects the front and rear of the car body. Many years ago, the front and rear bumpers of the car were punched with steel plates into channel steel, and riveted or welded together with the frame longitudinal beam. There is a large gap with the car body. With the development of the automobile industry and the extensive application of engineering plastics in the automobile industry, the automobile bumper, as an important safety device, is also on the road to innovation. Today's car front and rear bumpers not only maintain In addition to the original protection function, it is also necessary to pursue harmony and unity with the ...

Problems solved by technology

[0003] In the process of using the existing injection molding device, when the injection molding of the mold is completed, most of the ejector pins are used to eject the injection molded mold. In the process, due to the lack of stability between the structures, it is easy to cause the device to explode, which affects the quality of its injection molding, and the efficiency of the device's injection molding is low. Therefore, we propose a lightweight automobile bumper injection molding device and its injection molding. method
