Packaging plastic injection molding machine with injection mold calibration function

Abstract

The invention relates to the technical field of injection molding machines, in particular to a packaging plastic injection molding machine with an injection mold calibration function. The packaging plastic injection molding machine with the injection mold calibration function comprises a base, wherein the other side of a hydraulic push rod is fixed to the outer wall of a movable frame; the sides, close to each other, of a first fixed frame and the movable frame are connected with a first mold and a second mold through calibration mechanisms correspondingly; the calibration mechanisms comprise positioning cavities; two-way threaded lead screws are arranged in the positioning cavities; the upper ends and the lower ends of the outer sides of the two sets of two-way threaded lead screws are in threaded connection with lead screw sleeves; and locking mechanisms are arranged at the upper ends and the lower ends of the first mold and the second mold. According to the packaging plastic injection molding machine with the injection mold calibration function provided by the invention, the problems that the first mold and the second mold fall down during long-time production, deviation is likely to be generated during positioning, secondly, loosening and deviation can be generated due to insufficient locking force between the first mold and the second mold, and the internally-machined plastic packaging box is damaged are effectively solved.

Description

technical field [0001] The invention relates to the technical field of injection molding machines, in particular to a packaging plastic injection molding machine with the function of calibrating injection molds. Background technique [0002] Injection molding machine is the main molding equipment for making thermoplastics or thermosetting plastics into various shapes of plastic products using plastic molding molds. Now when processing the packaging boxes of plastic products, most of them need to use injection molding machines to process plastic packaging. Operation, when processing the packaging box, first pour the raw materials into the hopper, drive the feeding screw to rotate through the motor rotation, and initially mix the raw materials inside, and then heat the raw materials through the heating device to form a plastic solution , and then the hydraulic push rod pushes the mobile frame, so that the first mold and the second mold are merged, and the solution enters the s...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to provide a packaging plastic injection molding machine with the function of calibrating the injection mold, so as to solve the problem that the mold may fall and deviate under the action of gravity when the production is carried out for a long time in the above-mentioned background technology. The molds are re-aligned manually, and deviations are likely to occur during the secondary positioning, resulting in internal strain of the guide block and guide rod when guiding the moving frame, and the gap between the molds during long-term use. Insufficient locking force will cause loosening and offset, which will cause damage to the internally processed plastic packaging box
