[0002] Injection molding machine is also called injection molding machine or injection machine. It is the main molding equipment that uses plastic molding molds to make plastic products of various shapes from thermoplastics or thermosetting plastics. It is divided into vertical, horizontal and all-electric types. The injection molding machine can heat the plastic and apply high pressure to the molten plastic to make it ejected and fill the mold cavity.

[0003] Chinese patent 201610342507.4 discloses an injection molding mechanism, which uses a hydraulic motor as a power source. The hydraulic motor has a high cost and a complex structure, and is easily damaged. Once damaged, it is difficult to repair and the repair cost is also high, resulting in poor working stability of the injection molding machine.

[0004] In response to this, a Chinese patent discloses a power device for an injection molding mechanism (patent number 201920926642.2).

It is characterized in that: a bottom plate is provided at the bottom of the shooting platform rear plate, the rear end of the bottom plate is below the reduction box, a support member is provided between the bottom plate and the reduction box, the bottom of the support member is connected to the bottom plate, and the top of the support member is against the bottom surface of the reduction box.

[0007] Furthermore, in the above-mentioned injection molding machine shooting platform, a reduction box opening is provided on the reduction box, and the reduction box opening is fixedly connected to the outer peripheral wall at the rear end of the shooting platform rear plate.

[0008] Furthermore, the above-mentioned injection molding machine shooting platform, wherein: the bottom plate is provided with an opening.

[0009] Furthermore, in the above-mentioned injection molding machine shooting platform, the opening on the bottom plate is rectangular.

[0010] Furthermore, the above-mentioned injection molding machine shooting platform, wherein: the portion between the opening and the rear end edge of the bottom plate forms a support plate, the support plate is located directly below the reduction box, a connecting rod is provided on the support plate, and the support member is connected to the connecting rod on the support plate.

[0011] Furthermore, the above-mentioned injection molding machine shooting platform, wherein: the support member is rod-shaped, nuts are provided at both ends of the support member, the outer periphery of the connecting rod is provided with an external thread, the nut at one end of the support member is threadedly connected to the connecting rod, and the nut at the other end is against the bottom of the reduction box.

[0012] The utility model has the following beneficial effects: the utility model sets a bottom plate and extends the bottom plate to the bottom of the reduction box, and sets a support member on the bottom plate to support the reduction box, thereby preventing the reduction box from falling off due to excessive vibration during injection molding, and preventing the reduction box from applying excessive gravity to the screw, causing deformation of the screw, thereby extending the service life of the equipment.
