Description

Technical Field

[0001] The utility model relates to the field of injection molding machine shooting platforms, in particular to a linear guide rail device for injection molding machine shooting platforms. Background Art

[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 eject and fill the mold cavity;

[0003] The conventional injection molding machine adopts composite bearing sliding friction between the guide rod and the injection molding table, which has large friction resistance and high pre-molding back pressure of the barrel screw. Based on this, the utility model proposes a linear guide device for the injection molding machine injection molding table to solve the above problems. Utility Model Content

[0004] In order to overcome the defects in the above-mentioned prior art, the utility model provides a linear guide device for a shooting platform of an injection molding machine. By improving the linear guide rod, the resistance between the slider and the linear guide rod is reduced by rolling friction, so that the shooting platform moves more smoothly and the pre-plastic back pressure is reduced. The linear guide rail itself has high processing accuracy, thereby further ensuring that the overall accuracy of the entire shooting platform part is more accurate.

[0005] Technical Solution

[0006] A linear guide rail device for a shooting platform of an injection molding machine comprises a shooting platform guide rod bracket, on which two linear guide rods are arranged, and the upper sides of the linear guide rods are rollingly connected with a shooting platform front plate and a shooting platform rear plate.

[0007] Furthermore, four first mounting parts are provided at the bottom of the front plate of the shooting platform, and linear sliders are fixedly provided on the first mounting parts.

[0008] Furthermore, two second mounting parts are provided at the bottom of the rear plate of the shooting platform, and the linear slider is fixedly provided on the second mounting parts.

[0009] Furthermore, the linear slider is rollingly connected to the linear guide rod.

[0010] Furthermore, the linear slider and the linear guide rod are connected via balls.

[0011] Furthermore, a pre-plasticizing motor is provided on one side of the rear plate of the shooting platform away from the front plate of the shooting platform.

[0012] Beneficial Effects

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] The linear guide rod is improved, and rolling friction is used to reduce the resistance between the slider and the linear guide rod, so that the shooting platform moves more smoothly and reduces the pre-plastic back pressure. The linear guide rail itself has high processing accuracy, which further ensures that the overall accuracy of the entire shooting platform is more accurate. BRIEF DESCRIPTION OF THE DRAWINGS
