[0002] Paper handbags, as an indispensable daily necessity in daily life, their convenience greatly facilitates people's carrying needs. Especially the stringed paper handbags, by opening holes on the upper edge, manually threading the handle rope with the end film through the holes and folding the film to fix it inside the paper bag, realizing the function of easy carrying.

[0003] In the related art, in the injection molding structure of the handle rope in the prior art, the forming mold, the extrusion mold, the rope feeding device, the rubber feeding device and the glue spraying component are integrated on the same bracket, realizing the automatic coating of the rope and the rubber. In this process, the rope feeding component accurately feeds the rope into the extrusion mold, the rubber is formed in the forming mold and then fed into the extrusion mold, and the glue spraying component performs the bonding treatment on the rubber at a critical moment. As the core component, the extrusion mold, its fixed mold and the moving mold work together, and through the coincidence and misalignment of the injection holes on the fixed mold and the moving mold, the coating of the rubber on the rope and subsequent cutting are completed.

[0004] However, although the mold misalignment cutting technology is effective, its accuracy requirements are extremely high. The misaligned surfaces of the molds must be closely fitted during cutting, otherwise it is easy to cause problems such as uneven cutting surfaces of the rope or difficulty in cutting; while the close fitting will cause serious wear at the misaligned parts after long-term use of the molds, and the grinding technology requirements are high and the replacement is inconvenient, there is room for improvement. Summary of the Utility Model

[0021] Optionally, the second resetting member is a resetting compression spring fixedly arranged on the base, and the resetting compression spring is fixedly connected to the side surface of the second sliding plate away from the first sliding plate.

[0022] By adopting the above technical solution, due to the cooperative setting of the resetting compression spring, during the sliding process of the first mold and the second mold, the resetting compression spring can ensure that the second mold automatically resets after moving, so as to ensure the smooth movement of the first mold and the second mold.

[0023] Optionally, a guiding inclined surface is arranged on the side edge of the guiding slide rail away from the base.

[0024] By adopting the above technical solution, it is convenient for the guiding slide rail to be better inserted into the corresponding guiding notch.

[0025] In summary, the present application includes at least one of the following beneficial technical effects:

[0026] 1. After the covering is completed, the first mold and the second mold in the abutting state move as a whole towards the direction close to the cutting knife under the drive of the external power and the second resetting member, so that the cutting knife slides relatively in the relief notch, and then the covered rope is cut off by the cutting knife, thereby improving the flatness of the cut surface of the rope, reducing the damage of materials and the production cost; after cutting, the external power drives the first mold to reset, and the second resetting member drives the second mold to reset, and so on in a cycle. With this setting, the flatness of the cut surface of the rope is improved, the wear of the mold is reduced, and the service life of the mold is prolonged. BRIEF DESCRIPTION OF THE DRAWINGS
