Description

Technical Field

[0001] The utility model relates to the field of bag manufacturing and processing, in particular to a bag shell molding mechanism. Background Art

[0002] The outer shell of the luggage is made by heating the plastic plate to soften it and make it plastic. The plastic plate is then placed on a vacuum forming machine. The outer shell mold rises and fits the plastic plate. The vacuum forming machine first blows air into the plastic plate to expand it, and then sucks air into it to adsorb the plastic plate onto the surface of the outer shell mold, thereby forming the shape of the outer shell mold.

[0003] Generally, the plastic plate is manually placed on the clamp, fixed, and then the clamp and the plastic plate are placed under a heating mechanism for heating. After heating, the clamp is picked up to cover the plastic plate on the mold. Workers may be burned when taking the heated plastic plate, which is less safe. Utility Model Content

[0006] A bag shell forming mechanism comprises a workbench, a mounting frame is fixedly connected to the workbench, and a mounting chamber is provided on the surface of the workbench, a vacuum chamber is fixedly connected to the bottom of the mounting chamber, a lifting mechanism is arranged in the vacuum chamber, a connecting plate is fixedly connected to the lifting mechanism, a shell mold is fixedly connected to the upper part of the connecting plate, the side of the vacuum chamber is a heating chamber, guide rails are fixedly connected to the two sides of the upper part of the workbench, and the material table and a pressing frame are also included, slide grooves are provided on both sides of the material table, the material table is slidably connected to the workbench through the guide rails and the slide grooves, and the material table is located at the upper part of the vacuum chamber, a through hole is provided on the material table, a vertical cylinder 1 is fixedly connected to the four corners of the upper part of the material table, the pressing frame is located at the upper part of the material table, and the four corners of the pressing frame are respectively fixedly connected to the output shafts of four cylinders 1, a screw 1 is rotatably connected to the inner side wall of the workbench, and the bottom of the material table is fixedly connected to the screw 1 slider.

[0007] By adopting the above technical solution, the plastic plate is placed upright on the material table, covering the through hole of the material table. The cylinder drives the pressing frame to descend and press the plastic plate. Then, the lead screw rotates, and its slider drives the material table to move into the heating chamber to heat the plastic plate above the material table to soften it and produce plasticity. Then, the lead screw drives the material table and the heated plastic plate back to the top of the vacuum chamber. The lifting mechanism drives the outer shell mold above the connecting plate to rise through the through hole of the material table to lift the plastic plate. The vacuum pump in the outer shell mold then blows and sucks air on the plastic plate to make it adsorbed on the surface of the outer shell mold, thereby forming it.

[0008] Preferably, the lifting mechanism includes a second lead screw and a scissor frame, wherein the second lead screw is horizontally rotatably connected to the bottom of the vacuum chamber, the two feet at one end of the scissor frame are respectively hinged to the bottom of the vacuum chamber and the slider of the second lead screw, and the two feet at the other end are respectively hinged and slidably connected to the bottom of the connecting plate.

[0009] By adopting the above technical solution, the second lead screw rotates, and its slider drives one foot at the lower end of the scissors frame to move and approach the other foot at the same time, so that the scissors frame stretches out, drives the shell mold to rise and fit with the plastic plate, and there is no need to manually place the plastic plate on the shell mold.

[0010] Preferably, a water spray gun is fixedly connected to the mounting frame.

[0011] By adopting the above technical solution, dust and impurities on the surface of the shell mold can be cleaned to prevent pits from being generated on the surface of the molded product.

[0012] Preferably, a vertical cylinder 2 is fixedly connected to the top of the mounting frame, an output shaft of the cylinder 2 passes through the top of the mounting frame, and an arched pressure plate is fixedly connected to the output shaft of the cylinder 2.

[0013] By adopting the above technical solution, cylinder 2 pushes the arched pressing plate down to press the material table to prevent the moving table from moving when the plastic plate is being adsorbed and formed, thereby affecting its forming.

[0014] Preferably, a fan is fixedly connected to the top of the mounting frame.

[0015] By adopting the above technical solution, pungent gas will be generated after the plastic plate is heated, and the gas will be sucked to other places through the fan to reduce the harm to workers. BRIEF DESCRIPTION OF THE DRAWINGS
