Technical Field

[0002] There are various material selections for the outer shell of a trolley case. Among them, the material has good formability, a relatively hard texture, and a high density, so the cost is relatively low. Its surface can be subjected to various treatments, such as electroplating, vacuum coating, printing, or painting, which enables the plastic shell to have a diverse appearance. However, a major drawback of the plastic material is its relatively heavy weight and poor pressure resistance, which means that the plastic trolley case is more likely to crack when impacted. When the trolley case is being formed;

[0003] In the utility model with the application number 202122817284.1, a forming device for a trolley case shell is disclosed. By rotating the rotating shaft, the support rod can push the push plate under the action of the first external thread and the second external thread, so that the formed workpiece can be pushed out of the cavity, and the material taking is relatively convenient. The cooling liquid can be circulated in the cooling cavity and the radiator by a water pump, so that the workpiece in the cavity can be cooled cyclically, the cooling speed can be accelerated, and the use effect can be improved;

[0004] However, when the above-mentioned forming device for a trolley case shell is used for forming processing, it is necessary for workers to manually move the heated sheet material to between the processing head and the cavity, making the feeding process relatively difficult and likely to affect the forming processing efficiency of the trolley case box body. After the above-mentioned forming device for a trolley case shell extrudes and forms the shell, it is necessary for workers to manually take out the formed shell, and automated forming processing cannot be achieved. Therefore, the utility model proposes a forming device for a trolley case shell to solve the problems existing in the prior art. Content of the Utility Model

SPECIFIC EMBODIMENTS

[0018] In order to deepen the understanding of the present utility model, the following will further elaborate on the present utility model in combination with embodiments. The present embodiments are only used to explain the present utility model and do not constitute a limitation on the protection scope of the present utility model.

[0019] According to Figure 1 , Figure 2 , Figure 3As shown in the figure, this embodiment provides a forming device for a suitcase shell, which includes a workbench 1, a heating and feeding mechanism, a mold closing and forming mechanism, and a blanking mechanism. The heating and feeding mechanism includes a bracket 2, a heating box 3, an electric heating tube 4, a vertical plate 5, a feeding roller 6, and a motor 7. The bracket 2 is fixedly arranged on the workbench 1, and the heating box 3 is fixedly arranged in the middle of the top of the bracket 2. The electric heating tubes 4 are fixedly arranged in two rows on both sides inside the heating box 3. The vertical plates 5 are symmetrically and fixedly arranged in the middle above the heating box 3. The feeding rollers 6 are symmetrically and rotatably arranged inside the vertical plates 5. The motor 7 is fixedly arranged on the front side of one of the vertical plates 5. The upper and lower ends of the heating box 3 are open in the middle. The output end of the motor 7 is drivingly connected to a set of feeding rollers 6. The mold closing and forming mechanism is arranged on both sides of the workbench 1, and the blanking mechanism is arranged below the mold closing and forming mechanism. Before the shell is formed, the sheet material is inserted between the feeding rollers 6 first. The motor 7 drives a set of feeding rollers 6 to rotate and frictionally drives the sheet material to descend into the heating box 3. The electric heating tubes 4 are energized to generate heat to heat the sheet material, which is convenient for mold closing and forming. The feeding rollers 6 are used to push the sheet material down for feeding, solving the problem that it is difficult to manually assist in feeding the heated sheet material into the mold 9 during the feeding process.

[0020] The mold closing and forming mechanism includes a first electric telescopic rod 8, a mold 9, a slide rail 10, a slider 11, a cutting blade 12, and a cooling mechanism. The first electric telescopic rods 8 are symmetrically and fixedly arranged on the workbench 1. The mold 9 is fixedly arranged on the telescopic ends of the first electric telescopic rods 8. The slide rails 10 are symmetrically and fixedly arranged on the front and back of the workbench 1. The sliders 11 are symmetrically and fixedly arranged below the mold 9. The sliders 11 cooperate with the slide rails 10 to slide. The cutting blade 12 is fixedly arranged above the mold 9. Another set of the mold 9 is connected with a cooling mechanism. The blanking mechanism is arranged inside one of the molds 9. When forming, when the heated sheet material is fed between the molds 9 driven by the feeding rollers 6, the first electric telescopic rod 8 extends to drive the molds 9 to move towards each other to close the mold and form the sheet material. When the mold 9 moves, it drives the slider 11 to slide along the slide rail 10 to keep the mold 9 stable. The cutting blade moves synchronously with the mold 9 to cut the sheet material when the mold is closed.

[0021] The cooling mechanism includes a water tank 13, a water pump 14, a water delivery pipe 15, a cooling cavity 16, and a water return pipe 17. The water tank 13 is fixedly arranged on the other side of the workbench 1. The water pump 14 is fixedly arranged on one side of the water tank 13. The water delivery pipe 15 is communicated between the water pump 14 and the mold 9. The cooling cavity 16 is opened inside another set of the mold 9. The water return pipe 17 is communicated between the upper part of the mold 9 and the water tank 13. When the sheet material is formed under the extrusion of the mold 9, the water pump 14 is started to pump the water in the water tank 13 into the cooling cavity 16 to cool the sheet material with cold water to accelerate the forming speed.

[0022] The blanking mechanism includes a second electric telescopic rod 18, an ejecting block 19 and a through groove 20. The second electric telescopic rod 18 is fixedly arranged outside one side of the mold 9. The ejecting block 19 is fixedly arranged at the telescopic end of the second electric telescopic rod 18. A through groove 20 is formed in the middle of the workbench 1. The ejecting block 19 is attached to the inside of the mold 9. The through groove 20 corresponds to the mold 9 in the up and down positions. A material receiving box 21 is placed below the workbench 1. The material receiving box 21 corresponds to the through groove 20 in the up and down positions. After the forming is completed, the first electric telescopic rod 8 retracts to drive the mold 9 to move away and open the mold. At the same time, the second electric telescopic rod 18 extends to drive the ejecting block 19 to eject and push out the formed shell. After the shell is demolded, it automatically falls into the material receiving box 21 through the through groove 20 to realize automatic blanking, solving the problem that the formed shell needs to be manually taken out after the extrusion forming of the shell, which affects the processing efficiency.

[0023] Before the forming of the suitcase shell forming device, the sheet material is fed between the feeding rollers. The motor drives the feeding rollers to rotate and frictionally drives the sheet material to move downward into the heating box. The electric heating tube is energized to generate heat to heat and soften the sheet material. After the sheet material is heated, it continuously descends between the molds. Then the first electric telescopic rod extends to drive the molds to move towards each other. When the molds move, they slide along the slide rails with the cooperation of the sliders to keep the molds stable. When the molds are closed, the cutting blades intersect to cut the sheet material. The heated sheet material is extruded and formed by the molds. At the same time, the water pump is started to pump the water in the water tank to the cooling cavity to accelerate the cooling and forming of the shell. After the forming, the first electric telescopic rod retracts to drive the molds to separate. At the same time, the second electric telescopic rod extends to drive the ejecting block to extend and push out the shell to demold. The demolded shell automatically falls and enters the material receiving box through the through groove.
