Automobile sealing strip injection molding and heat setting method and device thereof

Abstract

The invention discloses an automobile sealing strip injection molding and heat setting method and a device thereof. The method specifically comprises the following steps: S100, producing EPDM (Ethylene-Propylene-Diene Monomer)/PP-TPV injection molding raw materials by adopting a high-temperature resistant reactor; S200, adding the EPDM/PP-TPV injection molding raw materials produced in the S100 into an injection molding cavity, and realizing rapid injection molding of the product in the injection molding cavity under the effect of a cooling device; S300, taking out the product subjected to injection molding in the S200 from the injection molding cavity by a manipulator. The device comprises a mechanical worktable, wherein a supporting base is arranged below the mechanical worktable; a lifting injection molding device, a cooling device and a TPV vulcanization preparation device are arranged above the mechanical worktable; the TPV vulcanization preparation device is used for producing the injection molding raw materials; one end of the lifting injection molding device is connected with the TPV vulcanization preparation device, and the other end of the lifting injection molding deviceis connected with the cooling device; a rotary supporting column is arranged between the TPV vulcanization preparation device and the mechanical worktable. The device is simple in structure and easyand convenient to operate, automobile sealing strips with excellent properties can be produced, and the automobile sealing requirement is met.

Description

technical field [0001] The invention relates to the technical field of production of automobile sealing strips, in particular to a method for injection molding and heat setting of automobile sealing strips and a device thereof. Background technique [0002] Automobile sealing strip is a kind of accessories with the largest amount of rubber used in automobiles except for tires. It is mainly used in the parts with gaps such as doors, windows, and hoods of automobiles. It plays the role of sealing, shock absorption, sound insulation, and decoration to prevent external sandstorms and rain. , dust, etc. invade the car to improve the working life and ride comfort of auto parts. Although it does not account for a large amount of the total cost of the car, it plays a vital role in the quality of the car. [0003] The existing automobile sealing strip still has the following problems in terms of material and its injection molding production process: [0004] (1) The main materials o...

Problems solved by technology

[0004] (1) The main materials of traditional automobile sealing strips are mainly soft PVC, CR, and NR. With the rapid development of the automobile industry, the appearance quality and internal performance of soft PVC, CR, and NR sealing strips, especially weather resistance Performance and service life can no longer meet the needs of cars and other high-end cars;

[0005] (2) Since the manipulator in the production workshop is often installed at a higher position, it is convenient to operate the manipulator, but the lower mold of the traditional injection mold is usually fixed on the lower workbench, and then through the mold clamping effect of the upper mold, it can be realized Injection molding of injection molded products in the lower mold, so the manipulator at a higher position cannot complete the clamping operation of the injection molded product in the lower mold at a lower position, but can only manually take out the injection molded product. It brings more troubles to the operators and reduces the production speed of automobile sealing strips. Since the injection molded products need a long period of cooling and molding, and the surface t
