Description

Technical Field

[0001] The utility model relates to the technical field of positioning tools, in particular to a positioning tool for product wrapping. Background Technique

[0002] The wrapping on the inner door panel of an automobile usually involves wrapping the armrest, middle trim panel, upper trim panel and interior parts on the inner door panel of the automobile.

[0003] During the process of wrapping the armrest, the armrest needs to be placed on the lower mold, the wrapping leather is placed on the product, and through the extrusion of the upper mold, the glued leather is pressed on the product. However, there is a problem of difficult positioning when wrapping the leather. It depends entirely on manual experience, resulting in misalignment and incomplete wrapping of the product, leading to waste of leather materials. For this reason, we propose a positioning tool for product wrapping to solve the existing problems. Summary of the Utility Model

[0004] The purpose of the utility model is to propose a positioning tool for product wrapping in view of the problems existing in the background technique.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A positioning tool for product wrapping, including a lower mold, an upper mold, a mounting frame, a mounting box and a pressure pump. The upper and lower inner walls of the mounting frame are respectively provided with an upper mold and a lower mold. A mold cavity is arranged inside the lower end of the upper mold. A template is arranged at the upper end of the lower mold. An mounting box is arranged at the upper end of the upper mold. Symmetrically distributed hydraulic rods three are arranged at the upper end of the mounting box. A pressure pump is connected and installed at the upper end of the mounting box in a communicating manner. A number of adsorption holes penetrating the mounting box are arranged inside the mold cavity.

[0006] Preferably, a pressure gauge is installed through the upper end inside of the mounting box. The pressure gauge monitors the pressure inside the mounting box.

[0007] Preferably, guide plates are arranged at both ends of the upper mold, and guide rods are arranged at the four corners of the mounting frame. The guide rods are slidably sleeved on the outer wall of the guide plates. The upper mold slides on the outer wall of the guide rods through the guide plates, playing a guiding role when docking with the lower mold.

[0008] Preferably, support legs are arranged at the lower end of the mounting frame, and the support legs are located at the four corners of the lower end of the mounting frame. The support legs support the four corners of the lower end of the mounting frame.

[0009] Preferably, a plurality of stroke holes are arranged inside the template, positioning rods are arranged inside the stroke holes, and a top block is arranged at the upper end of the positioning rods. The top block is used to close the upper end of the stroke hole and simultaneously move longitudinally following the positioning rod.

[0010] Preferably, a spring sleeved outside the positioning rod is arranged at the lower end of the top block, and a support ring connected to the inner wall of the travel hole is arranged at the lower end of the spring. The spring is elastically supported by the support ring.

[0011] Preferably, brackets are connected to all four sides of the mounting frame. Hydraulic rods I are arranged inside the brackets. Clamping plates are arranged at one ends of the hydraulic rods I. Hydraulic rods II are arranged inside the clamping plates. Pressing strips adapted to the outer shape of the corresponding surface of the template are arranged at the lower ends of the hydraulic rods II. The pressing strips press the side of the coated leather material.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] 1. A plurality of adsorption holes are formed in the mold cavity corresponding to the product inside the upper mold of the present utility model. Under the suction force of the negative pressure pump, an adsorption force is generated. After the leather material for wrapping the inner trim panel armrest is coated with glue, one end of the outer side is adsorbed and positioned through the adsorption holes, avoiding manual positioning. The positioning process is stable, avoiding the problem of dislocation. When fitting with the product outside the template, it reduces the waste of leather material and improves the qualified rate of the product at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
