Injection molding pre-machining device for preparing HAC-ECM porous orientation support

Abstract

The invention discloses an injection molding pre-machining device for preparing an HAC-ECM porous orientation support, and relates to the technical field of support production. The injection molding pre-machining device comprises a machining box, a first motor is fixedly installed on the outer wall of the top end of the machining box, and the output end of the motor is fixedly sleeved with an output shaft. The output shaft of the motor is in transmission connection with a transmission rod through a belt, the transmission rod is in transmission connection with a first rotating rod through a gear, and the two ends of the first rotating rod are rotatably connected with the inner wall of the machining box through bearings. The outer walls of the two sides of the first rotating rod are fixedly sleeved with rotating discs, the other sides of the rotating discs are fixedly sleeved with connecting rods, and the outer walls of the connecting rods are movably connected with moving rods. According to the injection molding pre-machining device, particles on the upper surfaces of sliding blocks are extruded through extrusion plates, the plastic particles are crushed, and the plastic particles can be conveniently heated and softened in the subsequent injection molding process.

Description

technical field [0001] The invention relates to the technical field of bracket production, in particular to an injection molding preprocessing device for preparing HAC-ECM porous orientation brackets. Background technique [0002] HAC-ECM is also called ECU. It refers to the electronic control module on the car. For example, the body computer is generally called BCM, the engine is called ECU, and the gearbox is called TCU. Most of the brackets used in electronic control modules on cars are porous oriented plastics. Bracket, the raw materials used to produce the bracket generally need to be crushed first when injection molding, and then undergo pre-processing processes such as heating, and then perform injection molding. [0003] Publication No. CN108407148 discloses a waste plastic pipe crushing device, including a shell, the bottom of the shell is provided with supporting legs, and the upper part of the shell is oppositely provided with a crushing plate I and a crushing pla...

Problems solved by technology

[0004] However, this device is only suitable for crushing some larger plastics, not suitable for crushing some smaller plastic particles, and the plastic raw materials fall from the crushing plate and the crushing plate too fast, resulting in incomplete crushing and inconvenient plastic follow-up. heated injection molding
