Abstract

The locking mold oil tank free hydraulic locking mode injection machine comprises a static mold plate, an active mold plate, cross rod fastened to both ends of the static mold and back mold plate, quick mold displacing oil tank on the static mold plate whose sticking end connected with the active mold plate. It also comprises stepwise sleeves and end cap, No.1 pin hole, with the stepwise sleeve and end cap fastened by bolt and two nuts into free positioning locking mold set, more than one No.1 electromagnetic pins on the circumference of the stepwise sleeve composed of pin inserting to the No.1 pin hole and the coil driving the up and down movement of the pin, No.2 pin hole and two ring boss at one side, sealing tightly with grooves surrounding the cross rod, forming four compression cavity by four end caps and active mold plates, inside the active mold plate having oil through hole connecting the compression cavity with the hydraulic source, sticking plate on the active mold plate with No.2 electromagnetic pin and through holes, with the No.2 electromagnetic pin being able to pass the through hole, sticking to the pin inside the No.2 pin hole and driving the up and down movement of the coil on the pin . Free from locking mold oil tank, with increased locking mold force, it solves the sealing issue of the locking mold oil tank, with small components, low requirements for the parts, small consumption materials and moving weight, long opening stroke of the active mold plate, and strong suitability for the mold.

Description

technical field

[0001] The invention relates to a hydraulic mold clamping injection molding machine without a mold clamping oil cylinder, in particular to a hydraulic mold clamping device without a mold clamping oil cylinder. technical background

[0002] At present, the injection molding machines used at home and abroad are generally in the toggle lock mode, the hydraulic lock mode and the newly emerging ball screw plus toggle composite lock mode. Elastic deformation force is used to clamp the mold. Due to the many hinged toggles and hinge points, the force length cannot be guaranteed to be equal during manufacturing and assembly. At the same time, a large amount of lubricating oil and a complicated lubrication system are required. Long running time will easily lead to wear and cause structural imbalance. The gap between the lengths of the toggle levers on both sides increases, and wear is accelerated, forming a vicious circle, which leads to crawling phenomenon in the open...
