Embodiment Construction
[0015] The present invention will be further described below in conjunction with the accompanying drawings.
[0016] See figure 1 —— Figure 4 , The injection mechanism of the vertical injection molding machine of the present invention includes: the injection cylinder body 1, which plays the role of connecting and fixing various parts as the main structure. The buckle 2 is fixed on the bottom of the shooting cylinder mandrel 3, and the buckle 2 is used to connect the screw rod of the material tube. The lower center of the shooting cylinder body 1 is provided with a through hole, the through hole is located directly below the shooting cylinder mandrel 3, the shooting cylinder mandrel 3 is connected with the shooting cylinder piston 6 and the shaft bolt sleeve 7, and the shooting cylinder piston 6 is set on the shooting cylinder core There is a hole on the top of the shaft 3 and the top of the shooting cylinder mandrel 3, and the shaft bolt sleeve 7 is embedded in the hole, an...

The invention relates to the technical field of vertical injection machines, in particular to an injection mechanism of a vertical injection molding machine. The injection mechanism comprises an injection cylinder body, wherein an injection cylinder flange is fixed at the middle of the injection cylinder body and sleeves an injection cylinder mandrel; a retaining ring is fixed at the bottom of theinjection cylinder mandrel; a through hole is formed in the center of the lower part of the injection cylinder body and positioned right below the injection cylinder mandrel; an injection cylinder piston movably sleeves the top of the injection cylinder mandrel; the exterior of the injection cylinder body is equipped with a first oil inlet and a second oil inlet; the first oil inlet communicateswith the space above the injection cylinder position; the second oil inlet communicates with the space below the injection cylinder piston; a motor bearing seat is fixed at the top end of the injection cylinder body; a hydraulic motor is fixed on the motor bearing seat and connected with the top end of a shaft bolt; and a shaft bolt sleeve sleeves the bottom of the shaft bolts and is inserted intothe top of the injection cylinder mandrel. The injection mechanism provided by the invention is more compact in structure, and thus the occupied space is small; furthermore, the more balanced actionand the high injection precision are achieved by adoption of a method that the injection cylinder piston moves up and down; and the overall cost is low.
Description
technical field [0001] The invention relates to the technical field of vertical injection molding machines, in particular to an injection mechanism of a vertical injection molding machine. Background technique [0002] The existing injection mechanism of the vertical injection molding machine mainly has problems such as large space occupation, poor stability of movement, low injection precision, and high manufacturing cost. [0003] Therefore, based on the defects of the above-mentioned injection mechanism of the existing vertical injection molding machine, it is necessary to improve the injection mechanism of the existing vertical injection molding machine. Contents of the invention [0004] The object of the present invention is to provide an injection mechanism for a vertical injection molding machine aimed at the deficiencies of the prior art. The injection mechanism for a vertical injection molding machine solves the existing problems of the existing injection mechani...
