Novel sealing strip-winding disc integrated injection mold for composite soft packaging

Abstract

The invention provides a novel sealing strip-winding disc integrated injection mold for composite soft packaging, and belongs to the field of injection molds. The novel sealing strip-winding disc integrated injection mold for composite soft packaging comprises a machine frame, a working table is arranged on the machine frame, an injection system is arranged in the middle of the working table, the injection system comprises a base plate and a face plate, the face plate is connected with a cover plate, pulling rods are sleeved with traction blocks, and a first template is symmetrically arranged between the base plate and the face plate; a second template is arranged above the first template, a third template is arranged below the first template, and the face plate, and the second template, the first template, the third template and the base plate encircle to form a sealed cavity of a winding disc shape; a plasticator is arranged on the face plate, and the plasticator communicates with the cavity; and a discharging system is arranged below the injecting system. The novel sealing strip-winding disc integrated injection mold for composite soft packaging has the beneficial effects of being low in manufacturing cost and high in production efficiency, one-piece winding discs can be injected and taken out smoothly, and no damage is made to the morphological structure of the winding discs.

Description

technical field [0001] The invention relates to the field of injection molds, in particular to a new type of injection mold integrated with sealing strips and winding disks for composite flexible packaging. Background technique [0002] When making composite flexible packaging, the edges of composite flexible packaging are usually sealed with sealing strips, and the sealing strips are often wound in coils during production for easy storage, transportation, and matching installation into corresponding production equipment. ; Due to the special structure of the winding disk, the inner surface of the left and right side plates is provided with inner lines, and the outer surface is provided with outer ribs, but the existing injection molds for making the winding disk still cannot overcome the problem of the winding disk. It is difficult to take out the whole injection molding and take it out smoothly. Therefore, limited by the current technical conditions, it is difficult to mak...

Problems solved by technology

[0002] When making composite flexible packaging, the edges of composite flexible packaging are usually sealed with sealing strips, and the sealing strips are often wound in coils during production for easy storage, transportation, and matching installation into corresponding production equipment. ; Due to the special structure of the winding disk, the inner surface of the left and right side plates is provided with inner lines, and the outer surface is provided with outer ribs, but the existing injection molds for making the winding disk still cannot overcome the problem of the winding disk. It is difficult to take out the whole injection molding and take it out smoothly. Therefore, limited by the current technical conditions, it is difficult to make an integrally formed winding disk with the traditional injection mold. The production method is to separate the winding disk into such a figure 1 The left fitting and the right fitting are shown, and then the left fitting and the right fitting are spliced ​​into one body through threaded connection; but this production method is always complicated, the process is cumbersome, and a large amount of manual splicing is required after the injection molded product comes out. Conducive to large-scale, mass-produced rapid production
