Description

Technical Field

[0001] This utility model relates to the technical field of punching, specifically to a punching device for automotive carpets. Background Technology

[0002] Car carpets are essential interior trim components for automobiles. They are mainly used to cover the metal parts at the bottom of the car's interior cavity and some important components. In order to make the car carpet fit the car floor, holes need to be made in the car carpet. The common method of making holes in car carpets is to punch holes with a mold, which is suitable for mass production.

[0003] For example, Chinese utility model patent CN204382642U discloses a mold for automotive carpet mats. A hydraulic lifting device is located below a support frame, and an upper mold is located below the hydraulic lifting device. A lower mold, used in conjunction with the upper mold, is vertically located below the upper mold. The lower mold is fixed to a support plate by screws. Both the upper and lower molds have cavities for accommodating the carpet mat, and the lower mold cavity also has a groove for using the PET needle-punched felt of the carpet mat. A cutting blade is welded to the outside of the upper mold cavity, and the lower mold has a cutting groove that mates with the cutting blade of the upper mold. This utility model, by adding punches, punch holes, and grooves for accommodating PET needle-punched felt to the original lower and upper molds, can complete three processes in a single pressing action, reducing the time required for automotive carpet mat production by 60%, increasing production efficiency, and reducing production costs. This utility model has a simple structure and is easy to use.

[0004] However, the existing devices described above have poor fixing effect on carpets. Due to the good flexibility of carpets, the carpet is prone to shifting when the fixing effect is poor during the punching process, which affects the punching effect of the device on the carpet. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an automotive carpet punching device that improves the fixing effect of the device on the carpet during the punching operation, prevents the carpet from moving during the punching process, and improves its practicality.

[0006] This utility model discloses a perforation device for automotive carpets, comprising a support platform, two upright plates fixedly mounted on the top of the support platform, the tops of the two upright plates being fixedly connected by a top plate, a lower mold fixedly mounted on the top of the support platform, and an upper mold fixedly mounted on the bottom of the top plate via a power mechanism. Multiple punches are mounted on the bottom of the upper mold. Two clamping mechanisms are symmetrically arranged on the top of the support platform. Each clamping mechanism includes multiple springs, each spring being parallelly and fixedly mounted on the top of the support platform, the top of each spring being fixedly connected via a fixing groove, the top of the fixing groove being fitted with a pressure plate. A connecting plate is fixedly mounted on the outer wall of the upper mold, and multiple extension rods are parallelly and fixedly mounted on the bottom of the connecting plate. The bottom of each extension rod, when moved via the connecting plate, is tightly fitted with the top of the pressure plate. This automotive carpet perforation device will... The carpet moves to the top of the lower mold, and both ends of the carpet are moved into the two fixing slots. The carpet comes into contact with the outer wall of the pressure plate, thus performing the initial fixing operation. The upper mold and punch are moved by the power mechanism. The carpet is punched by the punch. At the same time as the upper mold moves, the connecting plate and extension rod move simultaneously. The extension rod first comes into contact with the top of the pressure plate. The pressure plate then squeezes the carpet, fixing it to the top of the fixing slot under the limit of the inner wall of the fixing slot. Since the extension rod is longer than the punch, it comes into contact with the pressure plate before the punch, which improves the fixing effect of the device on the carpet during the punching operation, prevents the carpet from moving during the punching process, and improves practicality.

[0007] Preferably, the top of the lower mold has multiple punches, each punch being located directly above the corresponding punch. A connecting groove is provided on the outer wall of the lower mold, and a collecting plate is slidably installed at the bottom of the connecting groove. A collecting groove is provided at the top of the collecting plate, and the bottom of each punch is connected to the top of the connecting groove. By installing punches, it is convenient to transport the waste material after punching, and the waste material is collected through the collecting groove on the collecting plate.

[0008] Preferably, a limiting plate is fixedly installed at the top of the support platform, and a sliding plate is horizontally fixedly installed on the outer wall of the fixing groove. A sliding groove is opened through the sliding plate, and the limiting plate and the sliding groove are slidably connected. The sliding operation is carried out on the limiting plate through the sliding groove opened on the sliding plate, which facilitates the limiting operation of the fixing groove for sliding operation.

[0009] Preferably, a sealing plate is fixedly installed at one end of each of the fixed grooves, and one end of the pressure plate is slidably connected to the outer wall of the sealing plate. By installing the sealing plate, it is convenient to limit the operation of one end of the pressure plate.

[0010] Preferably, the power mechanism includes a cylinder, which is fixedly installed at the top of the top plate. The output end of the cylinder is fixedly connected to the top of the upper mold. Power is output through the bottom end of the cylinder, thereby synchronously driving the upper mold and the punch to move.

[0011] Preferably, the bottom end of the upper mold is fixedly installed with multiple fixed columns. The fixed columns that move during operation contact the top end of the lower mold, thereby effectively limiting the movement of the upper mold during lifting operations.

[0012] Preferably, the outer side wall of each of the vertical plates is fixedly connected to the bottom end of the top plate by a bracket. By installing the bracket, the stability of the connection between the vertical plate and the top plate is improved.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This car carpet punching device moves the carpet to the top of the lower mold and moves both ends of the carpet into the interior of the two fixing slots. The carpet is initially fixed by contacting the outer wall of the pressure plate. The upper mold and punch are moved by the power mechanism. The carpet is punched by contacting the punch. At the same time as the upper mold moves, the connecting plate and extension rod are moved simultaneously. The extension rod first contacts the top of the pressure plate. The pressure plate then squeezes the carpet, fixing it to the top of the fixing slot under the limitation of the inner wall of the fixing slot. Since the extension rod is longer than the punch, it contacts the pressure plate before the punch, which improves the fixing effect of the device on the carpet during the punching process, prevents the carpet from moving during the punching process, and improves its practicality.
