Abstract
The utility model provides a positioning mechanism of a pressure maintaining plunger piston of an injection molding machine. The positioning mechanism comprises a material barrel body of the injection molding machine, wherein a pressure maintaining oil cylinder is connected to the material barrel body; and the pressure maintaining plunger piston of the pressure maintaining oil cylinder is communicated with the material barrel body. The positioning mechanism is characterized in that one side of the pressure maintaining plunger piston is connected with an anti-rotation pin; the anti-rotation pin is connected with a guide block; a guide rod passes through the guide block; one end of the guide rod is connected with the material barrel body, and the other end of the guide rod is connected with a base of the pressure maintaining oil cylinder; and an electronic ruler mounted on one side of the base is connected with the guide block via a connecting rod. When the positioning mechanism works, the pressure maintaining oil cylinder drives the pressure maintaining plunger piston to slide and enter the material barrel body, the pressure maintaining plunger piston drives the anti-rotation pin connected to one side of the pressure maintaining plunger piston, the anti-rotation pin drives the guide block, and the guide block drives the electronic ruler to move via the connecting rod, so that the sliding position of the pressure maintaining plunger piston and the size of the pressure maintaining amount can be accurately controlled, thereby guaranteeing the quality and the precision of formed products, decreasing the reject rate and reducing the production cost.
Description
Technical field
The utility model relates to a kind of injection machine pressurize plunger detent mechanism, belongs to the plastics machinery field, is mainly used in the production plastic bottle preform.
Background technology
Injection machine is in process, in order to guarantee the quality of injection moulding workpiece, after injection machine is finished the injection technical process, screw rod in its injecting machine material tube still needs to continue to keep-up pressure and finishes the pressurize technical process, have only after pressurize technology is finished and just can change next technical process-melten gel over to, for next injection cycle is prepared, like this time of each injection cycle long, production efficiency is low.Therefore, someone has developed the independent pressure-keeping mechanism of injection machine, be that screw rod can be return at once and carries out melten gel action after injection was finished, its pressurize action is finished by special mechanism, and the pressure-keeping mechanism of prior art comprises the body that is connected the injecting machine material tube head, runner is arranged in the body, pressurize plunger with in joint pin plug cylinder and the cylinder on the body that runner communicates enters runner with the pressurize plunger, reaches the pressurize purpose, can shorten each injection cycle, increase work efficiency.The position depth that the pressurize plunger enters runner is directly connected to the size of pressurize amount, thereby influence the quality and the precision of shaped article, but, it is uncontrollable that the pressurize plunger of prior art enters the position of runner, therefore, the size of also uncontrollable pressurize amount has directly influenced the arrangement of follow-up moulding process.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, to provide a kind of and on the pressurize plunger detent mechanism is installed, can detect the sliding position of pressurize plunger, guaranteeing the injection machine pressurize plunger detent mechanism of the accuracy and the shaped article quality of pressurize amount.
The technical scheme of the utility model injection machine pressurize plunger detent mechanism is: comprise the injecting machine material tube body, connect the pressurize oil cylinder on the barrel body, the pressurize plunger of pressurize oil cylinder is communicated with the barrel body, it is characterized in that described pressurize plunger one side connects the anti-rotation pin, the anti-rotation pin connects guide pad, pass guide post in the guide pad, one of guide post connects the barrel body, the other end of guide post connects the base of pressurize oil cylinder, one side of base is installed electronic ruler, and electronic ruler connects guide pad through connecting rod.
Injection machine pressurize plunger detent mechanism of the present utility model, during work, the pressurize oil cylinder drives the pressurize plunger and slips in the barrel body, and the pressurize plunger drives the anti-rotation pin that is connected a side, and the anti-rotation pin drives guide pad, guide pad drives electronic ruler through connecting rod and moves, so just can accurately control the sliding position of pressurize post, control pressurize amount size, thereby the quality and the precision of assurance shaped article, reduce percent defective, reduce production costs.
The utility model discloses a kind of injection machine pressurize plunger detent mechanism, install and fix piece on the described barrel body, one of guide post is connected on the fixed block, and fixed block has been arranged, and guide post is easy to connect.One side mounting plate of described base, electronic ruler is installed on the fixed head, and fixed head has been arranged, and electronic ruler is easy for installation, firm.On the described guide pad connecting plate is installed, connecting rod connects connecting plate, and is easy to connect.
