Description
Technical Field
[0001] This utility model belongs to the field of automotive parts manufacturing technology, and specifically relates to an integrated cutting and injection molding equipment for soft sealing strips. Background Technology
[0002] With the rapid development of my country's automobile industry, automobile production scale is becoming increasingly large, and the demand for sealing strips, as an integral part of automobiles, is also increasing. A complete sealing strip requires two production processes, cutting and injection molding, to form a finished product. To meet the demand for large-volume production, automated production lines integrating cutting and injection molding are being established to improve production efficiency.
[0003] Previously, for flexible sealing strips requiring corner joints, the cutting and injection molding processes were performed on separate machines in different locations. This required multiple personnel to operate the equipment and transport the products. Furthermore, because flexible sealing strips are inherently soft, the traditional process involved operators manually holding the product and inserting it into the cutting machine, which was time-consuming, labor-intensive, and reduced production efficiency. Therefore, it is necessary to design an integrated cutting and injection molding machine for flexible sealing strips. Utility Model Content
[0004] Purpose of the utility model: In order to overcome the above shortcomings, the purpose of this utility model is to provide an integrated cutting and injection molding equipment for soft sealing strips, which has a simple structure and reasonable design, realizes the integration of injection molding and cutting, and solves the above-mentioned technical problems.
[0005] Technical solution: In order to achieve the above objectives, this utility model provides an integrated cutting and injection molding equipment for soft sealing strips, including a worktable, a set of servo-driven punching stations and injection molding corner mold stations. The injection molding corner mold stations are located in the middle of the worktable, and the servo-driven punching stations are slidably located at both ends of the worktable.
[0006] The injection molding corner mold station includes an injection mold, a micro injection molding machine, and a contour clamping mechanism. The injection mold is set on the worktable and connected to the micro injection molding machine. The contour clamping mechanism is located on both sides of the injection mold.
[0007] During production, the soft sealing strip is first injection molded at the injection corner mold station. At the same time, the servo-driven punching station slides to the cutting position to cut, realizing the integrated cutting and injection molding of the soft sealing strip.
[0008] Furthermore, the servo-driven punching station includes a servo slide and a punching fixture. A linear guide rail is provided on the worktable, the servo slide is slidably mounted on the linear guide rail, and the punching fixture is mounted on the servo slide. The servo slide can drive the punching fixture to move precisely to the cutting position along the linear guide rail.
[0009] Furthermore, the injection mold is provided with at least one set of injection mold cavities, which are connected to a micro injection molding machine. At least one set of reference blocks is provided in the upper middle 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 cavities for injection molding, and the reference blocks assist in the clamping and installation of the soft sealing strip.
[0010] Furthermore, the injection mold cavity includes an upper mold and a lower mold, which are connected by a pivot shaft, and the upper mold and the lower mold are provided with corner cavities.
[0011] Furthermore, the clamping mechanism includes a clamping cylinder, a contouring support plate, a contouring pressure plate, and a mounting block. The mounting block is located on the side of the injection mold and is L-shaped. The contouring support plate is located at one end of the mounting block, and the clamping cylinder is located at the other end of the mounting block. The contouring pressure plate is connected to the piston rod of the clamping cylinder and can press against the contouring support plate. The clamping cylinder drives the contouring pressure block to move downward, clamping the soft sealing strip between the contouring support plate and the contouring pressure plate.
[0012] Furthermore, both the contoured support plate and the contoured pressure plate have grooves on their opposite surfaces that conform to the shape of the flexible sealing strip. The groove design on the contoured support plate and the contoured pressure plate can both clamp the flexible sealing strip and prevent damage to its shape due to pressure.
[0013] Furthermore, the feed inlet of the punching fixture is equipped with a punching guide block. The flexible sealing strip smoothly enters the punching fixture through the guidance of the punching guide block.
[0014] Furthermore, it also includes a frame, with the worktable mounted on the frame and the micro injection molding machine mounted on the inner side wall of the frame.
[0015] As can be seen from the above technical solution, this utility model has the following beneficial effects:
[0016] 1. This utility model provides an integrated cutting and injection molding equipment for soft sealing strips. While the soft sealing strip completes the corner injection molding process at the corner injection mold station, the servo-driven punching stations on both sides move to the cutting position to complete the cutting. This realizes the integrated cutting and injection molding of soft sealing strips, which greatly saves equipment costs and labor costs and improves production efficiency.
[0017] 2. This utility model 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 and affect the injection molding effect. On the other hand, it will not cause disturbance during the process of the soft sealing strip entering the punching fixture and affect the cutting accuracy. The punching guide block lifts the tail of the soft sealing strip and guides it smoothly into the punching fixture, which saves time and effort and has a high degree of automation.

[0028] The injection molding corner mold station 3 includes an injection mold 31, a micro injection molding machine 32, and a contour clamping mechanism 33. The injection mold 31 is set on the workbench 1 and is connected to the micro injection molding machine 32. The contour clamping mechanism 33 is set on both sides of the injection mold 31.
[0029] like Figure 3 As shown, the servo-driven punching station 2 includes a servo slide 21 and a punching fixture 22. The worktable 1 is provided with a linear guide rail 11. The servo slide 21 is slidably mounted on the linear guide rail 11, and the punching fixture 22 is mounted on the servo slide 21.
[0030] In this embodiment, as Figure 4 As shown, the injection mold 31 has at least one set of injection mold cavities 311, which are connected to the micro injection molding machine 32. At least one set of reference blocks 312 is located in the upper middle part of the injection mold 31, and the injection mold cavities 311 are located on both sides of the reference blocks 312. In this embodiment, there are two sets of injection mold cavities, with two cavities in each set. The specific number of injection mold cavities can be selected as needed. It should be noted that the position and pairing of the injection mold cavities 311 and the reference blocks 312 are determined according to the product mold connection requirements. Two injection mold cavities 311 can share one reference block 312, or one injection mold cavity 311 can use one reference block 312.
[0031] Specifically, such as Figure 5 As shown, the injection mold cavity 311 includes an upper mold 3111 and a lower mold 3112, which are connected by a rotating shaft. The upper mold 3111 and the lower mold 3112 are provided with corner cavities.
[0032] like Figure 6 As shown, the clamping mechanism 33 includes a clamping cylinder 331, a contouring support plate 332, a contouring pressure plate 333, and a mounting block 334. The mounting block 334 is located on the side of the injection mold 31 and is L-shaped. The contouring support plate 332 is located at one end of the mounting block 334, and the clamping cylinder 331 is located at the other end of the mounting block 334. The contouring pressure plate 333 is connected to the piston rod of the clamping cylinder 331 and can be pressed onto the contouring support plate 332.
[0033] The contoured support plate 332 and the contoured pressure plate 333 are provided with grooves on their opposite surfaces that fit the shape of the soft sealing strip.

[0035] like Figure 7 As shown, it also includes a frame 4, the worktable 1 is mounted on the frame 4, and the micro injection molding machine 32 is mounted on the inner side wall of the frame 4.
[0036] The working principle of the integrated cutting and injection molding equipment for soft sealing strips disclosed in this utility model is as follows:
[0037] The operator places the soft sealing strip 5 on the injection mold cavity 311 and the contour plate 332 on the injection mold 31, with one end close to the reference block 312 and the other end placed on the guide opening of the punching guide block 221 on the punching fixture 22. At this time, the strip loading is completed.
[0038] The operator starts the equipment, and the contour platen 333 moves down and clamps the soft sealing strip 5 under the drive of the clamping cylinder 331. Then the injection mold cavity 311 closes and begins to connect the mold. The servo-driven punching station 2 on both sides drives the punching fixture 22 on it to move forward. The soft sealing strip 5 enters the punching fixture 22 for punching processing through the guidance of the punching guide block 221.
[0039] After the punching is completed, the servo slide 21 drives the punching fixture 22 on it to move backward. After the mold is connected, the injection mold cavity 311 on the injection mold 31 rotates and opens, and the contour platen 333 moves up and opens. At this time, the processing of the soft sealing strip 5 is completed.
[0040] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements can be made without departing from the principle of the present utility model, and these improvements should also be considered within the protection scope of the present utility model.
