Abstract
The invention relates to a pressure maintaining plunger positioning mechanism for an injection molding machine, which comprises a charging cylinder body of the injection molding machine, wherein a pressure maintaining oil cylinder is connected on the charging cylinder body; and a pressure maintaining plunger of the pressure maintaining oil cylinder is communicated with the charging cylinder body. The pressure maintaining plunger positioning mechanism is characterized in that: a rotation preventing pin is connected to one side of the pressure maintaining plunger and is connected with a guide block; a guide rod passes through the guide block; the charging cylinder body is connected to one end of the guide rod, and a base of the pressure maintaining oil cylinder is connected to the other end of the guide rod; and an electronic ruler is arranged on one side of the base, and is connected with the guide block by a connecting rod. When the pressure maintaining plunger positioning mechanism operates, the pressure maintaining oil cylinder drives the pressure maintaining plunger to slide in the charging cylinder body, the pressure maintaining plunger drives the rotation preventing pin connected to one side of the pressure maintaining plunger, the rotation preventing pin drives the guide block, and the guide block drives the electronic ruler to move by the connecting rod, so that the sliding position and pressure maintaining amount of the pressure maintaining plunger can be controlled accurately; and thus, the quality and accuracy of finished products are ensured, and the rejection rate and production cost are reduced.
Description
Technical field
The present invention relates to a kind of injection machine pressurize plunger detent mechanism, belong to the plastics machinery field, be 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 objective of the invention is provides a kind of and on the pressurize plunger detent mechanism is installed in order to overcome the shortcoming of prior art, can detect the sliding position of pressurize plunger, guarantees the injection machine pressurize plunger detent mechanism of the accuracy and the shaped article quality of pressurize amount.
The technical scheme of injection machine pressurize plunger detent mechanism of the present invention 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, passes 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, and a 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 invention, 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 invention 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.
