Description

Technical Field

[0001] This utility model relates to the field of shaping fixture technology, specifically to an air-blowing shaping fixture. Background Technology

[0002] When using polypropylene and other plastics for injection molding of plastic cover products, it is usually necessary to use an air blowing and shaping fixture to shape the product. Specifically, when shaping the product, the product is placed on a carrier plate, and then the positioning and clamping tools on the carrier plate are used to fix the position of the product. Finally, air is blown into the product through the air holes on the surface of the carrier plate to maintain a certain air pressure inside the product and prevent the product from deforming due to the softness of the material itself during the cooling and shaping process.

[0003] In practical use, shaping fixtures are mainly suitable for shaping products of specific specifications and sizes. It is inconvenient to adjust the position of the clamping tool to install products of different specifications and sizes for air blowing shaping, which limits the scope of application of traditional air blowing shaping fixtures. At the same time, for plastic cover products with one side edge being curved, the regular-shaped traditional clamping tool is not convenient to position and fix the product from the curved position of the product. Utility Model Content

[0004] The purpose of this invention is to provide an air-blowing shaping fixture to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] The air-blowing shaping fixture includes:

[0007] A carrier plate, with a limit block fixed on its top surface, two columnar slots inside the carrier plate, and multiple air outlets communicating with the columnar slots on the surface of the carrier plate, and an air inlet pipe fixed to one end of the carrier plate.

[0008] The clamping assembly includes a double-headed cylinder and a second cylinder that are fixedly connected to the carrier plate. Each of the two output ends of the double-headed cylinder is fixed with a clamping rod. The output end of the second cylinder is drivenly connected to two clamping rods, and the clamping rods are slidably connected to the clamping rods.

[0009] The positioning component includes a cylinder three fixedly connected to a carrier plate, a crossbeam fixed to the output end of the cylinder three, an electromagnet embedded inside the crossbeam, and multiple positioning posts slidably inserted inside the crossbeam and attracted and fixed to the electromagnet.

[0010] Furthermore, a flexible tube is fixedly connected between one end of the two columnar slots, and an exhaust pipe is fixedly connected to the end of one columnar slot opposite to the flexible tube.

[0011] Furthermore, the top surface of the carrier plate has two sliding grooves, and the output end of the double-headed cylinder is fixed with a slider that is slidably connected to the sliding groove. The slider is fixedly connected to a clamping rod at a corresponding position.

[0012] Furthermore, the output end of the second cylinder is fixed with a push rod, and the two ends of the push rod are respectively slidably inserted into the corresponding clamping rods.

[0013] Furthermore, a slot is provided on one side of the clamping rod one, and a block is fixed at one end of the clamping rod two to slide and engage with the slot.

[0014] Furthermore, the positioning component also includes two guide rails that are fixedly connected to the carrier plate, and the guide rails are slidably connected to the crossbeam.

[0015] Furthermore, the outer side of the crossbeam is provided with multiple rectangular holes at equal intervals, which are slidably connected to the positioning posts at corresponding positions, and one end of the positioning post is rotatably connected to a rubber wheel.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. By placing the plastic cover on the carrier plate surface and making the limiting block abut against one side of the inside of the plastic cover, the two output ends of the double-headed cylinder retract their lengths, causing the two clamping rods to move closer to each other and clamp the plastic cover from both ends. At the same time, the output end of the second cylinder extends, causing the push rod to move the two clamping rods towards the limiting block, so that the clamping rods and the limiting block clamp one side of the plastic cover. This achieves automatic clamping and mounting of one side of the plastic cover onto the carrier plate. Furthermore, the first clamping rod can move laterally along the carrier plate, facilitating the clamping of plastic covers of different lengths. The second clamping rod can move longitudinally along the first clamping rod, and the two clamping rods can also slide laterally along the push rod, thus facilitating the cooperation of the first and second clamping rods to clamp and fix plastic covers of different specifications and sizes onto the carrier plate surface, which helps to improve the versatility of the shaping fixture.

[0018] 2. A crossbeam is slidably connected to the surface of the carrier plate, and multiple positioning posts are movably inserted inside the crossbeam. According to the shape of the curved side of the plastic cover, the multiple positioning posts can be pushed towards the curved side of the plastic cover, so that the rubber wheel at one end of the positioning post can contact the curved side of the plastic cover. Then, the electromagnet inside the crossbeam is energized to attract and fix the positioned positioning post after adjustment. Then, the cylinder three moves the crossbeam and multiple positioning posts slightly towards the plastic cover, so that the multiple positioning posts can adapt to the curved side of the plastic cover and abut and fix one side of the plastic cover. Furthermore, according to the length of the plastic cover, an appropriate number of positioning posts can be inserted and installed on the crossbeam. Each positioning post can move an appropriate distance towards the plastic cover according to the shape characteristics of the plastic cover to position and fix the irregular plastic cover, which facilitates the installation and fixation of plastic covers with different shapes.

Detailed Implementation

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] Example 1, please refer to Figure 1 - Figure 5In this embodiment of the utility model, the air-blowing shaping fixture includes a carrier plate 100, a limiting block 110 fixed on the top surface of the carrier plate 100, two columnar slots inside the carrier plate 100, and multiple air outlets 120 communicating with the columnar slots on the surface of the carrier plate 100. An air inlet pipe 130 is fixedly connected to one end of the carrier plate 100. A clamping assembly 200 is provided on one side of the top surface of the carrier plate 100. The clamping assembly 200, in cooperation with the limiting block 110, can clamp and fix the plastic cover product on the top of the carrier plate 100. The clamping assembly 200 includes a double-headed cylinder 210 and a second cylinder 220 fixedly connected to the carrier plate 100. The two ends of the double-headed cylinder 210... Each output end is fixed with a clamping rod 230. The output end of cylinder 220 is driven by two clamping rods 240. The clamping rods 240 are slidably connected to the clamping rod 230. A positioning component 300 is provided on the top surface of the carrier plate 100 away from the clamping assembly 200. The positioning component 300 can abut against the arc-shaped edge of the product. The positioning component 300 includes a cylinder 310 fixedly connected to the carrier plate 100. A crossbeam 320 is fixed to the output end of cylinder 310. An electromagnet 330 is embedded in the crossbeam 320. Multiple positioning posts 340 that are attracted and fixed to the electromagnet 330 are slidably inserted into the crossbeam 320.

[0027] Specifically, by setting two laterally adjustable clamping rods 230 and two longitudinally adjustable clamping rods 240 on the carrier plate 100, the clamping rods 230 and 240 can cooperate to clamp and fix one side of plastic covers of different specifications and sizes to the surface of the carrier plate 100. By arranging multiple positioning posts 340 on the outer side of the curved surface of the plastic cover, each positioning post 340 can abut against and fix the plastic cover at different positions with rubber wheels 341. Even if different types of plastic covers have curved surfaces with different curvatures, the multiple positioning posts 340 can adapt to the shape of the plastic cover and abut against and fix it on the outside of the two clamping rods 240. This allows for the clamping and installation of plastic covers of different specifications and sizes while facilitating the positioning and fixing of plastic covers of different shapes, thus improving the versatility of the shaping fixture.

[0028] like Figure 3 As shown, in this embodiment, a flexible hose 140 is fixedly connected between one end of two columnar slots, and an exhaust pipe 150 is fixedly connected to one end of a columnar slot away from the flexible hose 140. A solenoid valve is connected in series on the outside of the exhaust pipe 150.

[0029] In this embodiment, after the plastic cover is fixed to the surface of the carrier plate 100, an external air pumping device supplies air to the air inlet pipe 130. The air is delivered into the columnar slots inside the carrier plate 100 and then discharged from multiple air outlets 120, maintaining a certain air pressure inside the plastic cover to prevent deformation. A flexible hose 140 is fixedly connected between one end of two columnar slots, allowing air to pass between them. This ensures that multiple air outlets 120 above each columnar slot continuously blow air into the plastic cover. A pressure sensor can be installed inside the columnar slots to detect the overall air pressure in the space between the columnar slots and the plastic cover. Both the pressure sensor and the air pumping device are existing technologies, and their specific working principles are not described in detail.

[0030] In this embodiment, the air pumping device can be a cold air blower, so that the air pumped into the plastic cover is cold air. The high-pressure cold air can not only support the plastic cover, but also promote the rapid cooling and shaping of the plastic cover. After the shaping is completed, the solenoid valve on the exhaust pipe 150 can be opened to discharge the high-pressure air between the plastic cover and the columnar groove, and then the cooled and shaped plastic cover product can be taken out.

[0031] like Figure 3 and Figure 4 As shown, in this embodiment, the top surface of the carrier plate 100 has two sliding grooves 160. The two output ends of the double-headed cylinder 210 are each fixed with a slider 211 that is slidably connected to the corresponding sliding groove 160. The slider 211 is fixedly connected to the corresponding clamping rod 230, so that the output end of the double-headed cylinder 210 can move linearly along the sliding groove 160 with the clamping rod 230.

[0032] In this embodiment, a push rod 221 is fixed to the output end of cylinder 220. The two ends of the push rod 221 are respectively slidably inserted into the corresponding clamping rod 240. One end of the clamping rod 240 is provided with an insertion hole for slidably inserting into the push rod 221, so that the two clamping rods 240 can move in the same direction along the push rod 221 as the two clamping rods 1 230 move when they are not in contact with the plastic cover. This allows the right-angle limiting area formed by the clamping rods 240 and the clamping rods 1 230 to be fitted onto the corresponding corner position on the plastic cover later.

[0033] like Figure 3 As shown, in this embodiment, a slot is provided on one side of the clamping rod 230, and a block is fixed at one end of the clamping rod 240 to slide and engage with the slot, so that the two clamping rods 240 can move along the length of the clamping rod 230 and further abut against and fix it from the outside of the plastic cover.

[0034] In this embodiment, when it is necessary to use clamping rod 1 230 and clamping rod 240 to clamp the plastic cover product together, the plastic cover product is first placed on the surface of the carrier plate 100 and the inner side of the plastic cover abuts against the limiting block 110. Then, the two clamping rods 1 230 are moved closer to each other to clamp the plastic cover from both ends. Then, the two clamping rods 240 are moved along the clamping rod 1 230 toward the plastic cover so that the two clamping rods 240 abut against the outer side of the plastic cover.

[0035] In this embodiment, both clamping rod 230 and clamping rod 240 are fitted with rubber pads on the side near the plastic cover, so that clamping rod 230 and clamping rod 240 can flexibly and firmly clamp the plastic cover.

[0036] like Figure 3 and Figure 5 As shown, in this embodiment, the positioning component 300 also includes two guide rails 350 that are fixedly connected to the carrier plate 100. The guide rails 350 are slidably connected to the crossbeam 320. The outer side of the crossbeam 320 is provided with a plurality of rectangular holes 321 that are slidably connected to the positioning posts 340 at corresponding positions. One end of the positioning post 340 is rotatably connected to a rubber wheel 341.

[0037] In this embodiment, the positioning post 340 is first pushed towards the plastic cover so that the rubber wheel 341 at the end of the positioning post 340 contacts the plastic cover. Then, the electromagnet 330 is energized to attract and fix the moved positioning post 340. Finally, the crossbeam 320 moves the positioning post 340 slightly further towards the plastic cover so that the multiple rubber wheels 341 can abut against and fix the plastic cover. The number of positioning posts 340 inserted and installed on the crossbeam 320 can be selected according to the length of the plastic cover to abut against different positions of the plastic cover. The rubber wheels 341 are made of rubber, which allows the positioning post 340 to make flexible contact with the plastic cover.

[0038] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0039] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
