A steering gear chassis connecting sleeve injection method comprises any one of the steering gear chassis connecting sleeve injection mould, and further comprises the following steps:
s1: and (4) supporting and placing the upper die and the lower die.
And S2, injection molding raw material shaping treatment of the mold.
And S3, demolding.
Firstly, a user needs to use the lower molding mechanism 2, the bottom of the U-shaped groove 112 is conveniently buckled, the provided molding lug 201 and the molding press block 202 can correspond to the molding groove 304 arranged on the upper half part when in use, the side wall of the molding lug 201 is provided with the assembly line chute 203, the upper half part of the mold can be placed in a sliding and penetrating mode along the limiting cushion block 111, the limiting cushion block 111 on the side part of the U-shaped groove 112 is prevented from being clamped when sliding, the efficiency of placing the device is improved, the provided molding press block 202 can mold the connecting sleeve of the chassis of the steering machine, after molding is finished, demolding treatment is carried out, and the demolding efficiency is improved by adopting a cavity type demolding technology.
And S2, injection molding raw material shaping treatment of the mold.
The injection molding is that plastic is first added into a heating material cylinder of an injection machine, the plastic is heated and melted, and the plastic enters a mold cavity through a nozzle and a mold pouring system under the pushing of a screw rod or a plunger of the injection machine, and is hardened and molded into an injection molding product due to physical and chemical actions. The thermoplastic plastic injection molding has short molding cycle and high production efficiency, the melt has small abrasion to the mold, and plastic parts with complex shapes, clear surface patterns and marks and high dimensional precision can be molded in large batch; however, for plastic parts with large wall thickness variation, it is difficult to avoid molding defects. Compression molding is the process of adding plastic directly into an open mold cavity at a certain temperature, then closing the mold, and melting the plastic under heat and pressure to become a fluid state. Due to physical and chemical actions, the plastic is hardened into a plastic part with certain shape and size and unchanged at normal temperature. The compression molding is mainly used for molding thermosetting plastics, such as molding compounds of phenolic molding powder, urea-formaldehyde and melamine formaldehyde molding powder, glass fiber reinforced phenolic plastics, epoxy resin, DAP resin, organic silicon resin, polyimide and the like, and can also be used for molding unsaturated polyester dough DMC, sheet molding compound SMC, prefabricated integral molding compound BMC and the like.
