Description

Technical Field

[0001] The invention belongs to the technical field of automobile parts production, and in particular relates to a soft sealing strip cutting and injection molding integrated device and a working method thereof. Background Art

[0002] With the rapid development of my country's automobile industry, the scale of automobile production is getting larger and larger, and the demand for sealing strips as a part of automobiles is also increasing. A complete set of sealing strips needs to go through two production processes, cutting and injection molding, to form a complete finished product. In order to meet the demand for large quantities of products, an automated production line integrating cutting and injection molding is established to improve production efficiency.

[0003] In the past, soft sealing strips had corner joints, so the cutting and injection molding processes were processed on two different devices, which required multiple people to operate the equipment and transport the products. In addition, the soft sealing strips were soft, so the operators had to hold the products in their hands and insert them into the punching equipment, which was time-consuming and labor-intensive, and reduced production efficiency. Therefore, it is necessary to design an integrated cutting and injection molding equipment for soft sealing strips. Summary of the invention

[0004] Purpose of the invention: In order to overcome the above shortcomings, the purpose of the present invention is to provide a soft sealing strip cutting and injection molding integrated equipment and its working method, which has a simple structure and reasonable design, realizes the integration of injection molding and cutting, and solves the above technical problems.

[0005] Technical solution: In order to achieve the above-mentioned purpose, the present invention provides a soft sealing strip cutting and injection molding integrated equipment, including a workbench, a group of servo-driven punching stations and an injection molding corner mold station, wherein the injection molding corner mold station is arranged in the middle of the workbench, and the servo-driven punching station is slidably arranged at both ends of the workbench; The injection molding corner mold station comprises an injection mold, a micro injection molding machine and a contour clamping mechanism. The injection mold is arranged on a workbench, the injection mold is connected to the micro injection molding machine, and the contour clamping mechanism is arranged on both sides of the injection mold.

[0006] During production, the soft sealing strip is first injection molded by the injection molding corner mold station. At the same time, the servo drives the punching station to slide to the cutting position for cutting, realizing the integration of cutting and injection molding of the soft sealing strip.

[0007] Furthermore, the servo driven punching station includes a servo slide and a punching tool, the workbench is provided with a linear guide rail, the servo slide is slidably arranged on the linear guide rail, and the punching tool is arranged on the servo slide. The servo slide can drive the punching tool to move accurately to the cutting position along the linear guide rail.

[0008] Furthermore, the injection mold is provided with at least one group of injection mold cavities, the injection mold cavities are connected to the micro injection molding machine, at least one group of reference blocks are provided in the middle of the upper part of the injection mold, and the injection mold cavities are located on both sides of the reference blocks. The micro injection molding machine injects the injection material into the injection mold cavity for injection molding, and the reference blocks assist in the clamping and installation of the soft sealing strip.

[0009] Furthermore, the injection mold cavity includes an upper mold and a lower mold, the upper mold and the lower mold are connected by a rotating shaft, and corner cavities are provided in the upper mold and the lower mold.

[0010] Furthermore, the clamping mechanism includes a clamping cylinder, a profiling support plate, a profiling pressure plate and a mounting block, wherein the mounting block is arranged on the side of the injection mold, the mounting block is L-shaped, the profiling support plate is arranged at one end of the mounting block, the clamping cylinder is arranged at the other end of the mounting block, the profiling pressure plate is connected to the piston rod of the clamping cylinder, and the profiling pressure plate can be pressed on the profiling support plate. The clamping cylinder drives the profiling pressure block to move downward, and clamps the soft sealing strip between the profiling support plate and the profiling pressure plate.

[0011] Furthermore, the opposite surfaces of the profiling support plate and the profiling pressing plate are provided with grooves matching the shape of the soft sealing strip. The groove design on the profiling support plate and the profiling pressing plate can not only clamp the soft sealing strip, but also avoid damaging the shape of the soft sealing strip due to pressure.

[0012] Furthermore, a punching guide block is provided at the feed inlet of the punching tool, and the soft sealing strip smoothly enters the punching tool under the guidance of the punching guide block.

[0013] Furthermore, it also includes a frame, the workbench is arranged on the frame, and the micro injection molding machine is arranged on the inner wall of the frame.

[0014] Furthermore, a working method of a soft sealing strip cutting and injection molding integrated device comprises the following steps: S1, the operator places the soft sealing strip on the injection mold cavity and the contoured pallet on the injection mold, with one end close to the reference block and the other end placed on the guide opening of the punching guide block on the punching tooling. At this time, the strip installation is completed; S2, the operator starts the equipment, and the contoured pressing plate moves down and clamps the soft sealing strip under the drive of the clamping cylinder. Then the injection mold cavity is closed and the mold connection begins. At the same time, the servo-driven punching stations on both sides drive the punching tooling on them to move forward. The soft sealing strip is guided by the punching guide block into the punching tooling for punching processing; S3, after the punching is completed, the servo slide drives the punching tooling on it to retreat. After the mold connection is completed, the injection mold cavity on the injection mold rotates to open, and the contoured pressing plate moves up to open. At this time, the soft sealing strip processing is completed and the equipment can be removed.

[0015] It can be seen from the above technical solution that the present invention has the following beneficial effects: 1. The present invention provides an integrated cutting and injection molding equipment for soft sealing strips. While the soft sealing strips complete the corner injection molding process at the injection molding corner mold station, the servo-driven punching stations on both sides move to the cutting position to complete the cutting, thereby realizing the integrated cutting and injection molding of the soft sealing strips, greatly saving equipment costs and labor costs, and improving production efficiency.

[0016] 2. The present invention is designed with a clamping mechanism and a punching guide block. The clamping mechanism can clamp and lift the soft sealing strip on the equipment to ensure that it will not be disturbed during injection molding to affect the injection molding effect. On the other hand, no disturbance will be sent to affect the cutting accuracy during the process of the soft sealing strip entering the punching tool. The punching guide block can lift the tail of the soft sealing strip on the one hand, and can smoothly guide the soft sealing strip into the punching tool on the other hand, which saves time and labor and has a high degree of automation.
