[0002] Injection molding is a method of shaping industrial products. Products are usually made using rubber injection molding and plastic injection molding. The injection molding process requires the use of an injection molding machine. The injection molding machine is the main molding equipment that uses plastic molds to make plastic products of various shapes from thermoplastic or thermosetting materials. Injection molding is achieved through an injection molding machine and a mold.

[0003] After ring-shaped injection molded products are formed, they are often discharged directly into the receiving box below. This method can easily damage the products and requires workers to arrange them neatly for subsequent processing. Alternatively, manual unloading can be used to remove the products and arrange them neatly, but this poses safety hazards and is labor-intensive.

[0004] Therefore, it is necessary to invent a pneumatic expansion claw to solve the above problems. Utility Model Content

A mounting frame that can slide back and forth is installed on the inner side of the mounting base, and multiple sets of expansion claws that can slide back and forth are installed on the inner side of the mounting frame. The expansion claw includes a connecting pipe, a threaded pipe, a locking sleeve, a connecting head, an air supply pipe, and an expansion head.

[0007] By adopting the above technical solution, the three-axis transmission component is used to drive the pneumatic steering component, mounting base, mounting frame and expanding claw to move in the three-axis direction, and the pneumatic steering component is used to adjust the direction angle of the mounting base, mounting frame and expanding claw.

[0008] Optionally, the mounting base is n-shaped, with limit blocks fixedly connected to the inner walls of both the left and right sides of the mounting base, and a positioning block fixedly connected to the inner top wall of the mounting base, with a locking screw threaded to the lower end of the positioning block.

[0009] Optionally, the mounting bracket has a longitudinal positioning groove in the middle, and limit grooves are provided on both the left and right sides of the mounting bracket.

[0010] By adopting the above technical solution, the mounting bracket slides back and forth on the inner side of the mounting base.

[0011] Optionally, the positioning block is slidably connected to the positioning groove, and the limiting block is slidably connected to the limiting groove.

[0012] By adopting the above technical solution, the locking screw passes through the positioning groove from the bottom and is threaded to the positioning block, thereby locking and fixing the mounting bracket and the mounting base.

[0013] Optionally, the upper end of the threaded tube is fixedly connected to the connecting tube, the threaded tube is slidably connected to the positioning groove, the locking sleeve is threadedly connected to the upper end of the threaded tube, the connecting head is fixedly connected to the upper end of the threaded tube, and the gas supply tube is fixedly connected to the upper end of the connecting head.

[0014] By adopting the above technical solution, the threaded tube is inserted into the positioning groove from bottom to top, and then the locking sleeve is threaded to the upper end of the threaded tube, and the expansion claw is fixed to the inside of the mounting bracket.

[0021] The technical effects and advantages provided by this utility model in the above technical solution are as follows: 1. This utility model moves the expansion claw to the inside of the mold and inserts it into the inside of the ring-shaped product. As the ejector rod pushes the product out, the product is directly sleeved on the surface of the expansion claw. At this time, air is introduced into the expansion claw, causing the expansion head to expand and press tightly against the inner wall of the product, fixing the product on the surface of the expansion claw and thus clamping and fixing the product. Then, the three-axis transmission component and the pneumatic steering component work together to move the product and place it on the surface of the conveyor belt, which effectively improves the convenience and safety of product unloading.

Detailed Implementation

[0024] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0025] This utility model provides, for example Figures 1 to 4The pneumatic expansion claw shown includes a three-axis transmission component 1. A pneumatic steering component 11 is fixedly installed at the lower end of the Z-axis of the three-axis transmission component 1. A mounting base 2 is fixedly connected to the lower end of the steering block in the pneumatic steering component 11. A mounting frame 3 that can slide back and forth is installed on the inner side of the mounting base 2. The mounting base 2 is n-shaped. Limiting blocks 21 are fixedly connected to the inner walls of both the left and right sides of the mounting base 2. A positioning block 22 is fixedly connected to the inner top wall of the mounting base 2. A locking screw 23 is threaded to the lower end of the positioning block 22. A longitudinal positioning groove 31 is opened in the middle of the mounting frame 3. Limiting grooves 32 are opened on both the left and right surfaces of the mounting frame 3. The positioning block 22 is slidably connected to the positioning groove 31, and the limiting block 21 is slidably connected to the limiting groove 32. Multiple sets of expansion claws 4 that can slide back and forth are installed on the inner side of the mounting frame 3.

[0026] During use, the position of the mounting frame 3, multiple sets of expansion claws 4 and the product is adjusted by the three-axis transmission component 1, and the angle and direction of the mounting frame 3, multiple sets of expansion claws 4 and the product are adjusted by the pneumatic steering component 11.

[0027] Meanwhile, the front end of the mounting bracket 3 is a detachable sealing head. During the installation of the mounting bracket 3, the front end of the mounting bracket 3 is disassembled, and then the mounting bracket 3 is inserted into the inner side of the mounting base 2 from back to front, so that the limiting block 21 is inserted into the limiting groove 32 and the positioning block 22 is inserted into the positioning groove 31. Then, the sealing head at the front end of the mounting bracket 3 is locked and fixed. At this time, the mounting bracket 3 can slide back and forth inside the mounting base 2 to adjust the position of the mounting bracket 3. After adjusting the position, the locking screw 23 passes through the positioning groove 31 from bottom to top and is threaded to the lower end of the positioning block 22 to lock and fix the mounting bracket 3 and the mounting base 2 so as to be suitable for different molds. Then, the expansion claw 4 is installed on the surface of the mounting bracket 3. The appropriate number of expansion claws 4 is selected according to the product quantity, and the expansion claw 4 can slide back and forth so as to be suitable for products with different spacing.

[0028] See Figure 2 and Figure 4 The expansion claw 4 includes a connecting pipe 41, a threaded pipe 42, a locking sleeve 43, a connector 44, an air supply pipe 45, and an expansion head 46. The threaded pipe 42 is fixedly connected to the upper end of the connecting pipe 41 and is slidably connected to the positioning groove 31. The locking sleeve 43 is threadedly connected to the upper end of the threaded pipe 42. The connector 44 is fixedly connected to the upper end of the threaded pipe 42. The air supply pipe 45 is fixedly connected to the upper end of the connector 44. The expansion head 46 is fixedly connected to the lower end of the connecting pipe 41.

[0029] In addition, during the product unloading process, the mounting bracket 3 and the expansion claw 4 are first moved to the upper side of the mold using the three-axis transmission component 1. Then, the pneumatic steering component 11 adjusts the mounting bracket 3 to a vertical position, at which point the expansion claw 4 is horizontal. After the mold is opened, the three-axis transmission component 1 moves the mounting bracket 3 and the expansion claw 4 to the inside of the mold and inserts the expansion claw 4 into the inside of the ring-shaped product. As the ejector rod pushes the product out, the product will be fitted onto the surface of the expansion claw 4. At this time, air is injected into the expansion claw 4 to expand the expansion head 46 and fix the product.

[0030] Next, the three-axis drive unit 1 moves the mounting bracket 3, the expanding claw 4, and the product upwards out of the mold. Then, the pneumatic steering component 11 adjusts the mounting bracket 3 to a horizontal position, at which point the expanding claw 4 and the product are vertical. The three-axis drive unit 1 then moves the mounting bracket 3, the expanding claw 4, and the product to the upper side of the conveyor belt. At this point, the gas inside the expanding claw 4 is released, unlocking the product, which falls onto the surface of the conveyor belt. The conveyor belt then moves the product to the next process. The three-axis drive unit 1 then moves the mounting bracket 3 and the expanding claw 4 back to the upper side of the mold for standby. See Figure 4 and Figure 5 The expansion head 46 includes an air inlet pipe 461, a threaded head 462, a first connecting piece 463, a connecting rod 464, a second connecting piece 465, and a rubber sleeve 466. The upper end of the air inlet pipe 461 is fixedly connected to the threaded head 462, which is threadedly connected to the lower end of the connecting pipe 41. The first connecting piece 463 is fixedly connected to the lower end of the air inlet pipe 461. Multiple sets of connecting rods 464 are fixedly connected between the second connecting piece 465 and the air inlet pipe 461. The upper and lower ends of the rubber sleeve 466 are fixedly connected to the edges of the first connecting piece 463 and the second connecting piece 465, respectively.

[0031] Specifically, during the inflation process of the expansion claw 4, compressed air enters the interior of the expansion head 46 through the air supply pipe 45, the threaded pipe 42, and the connecting pipe 41 in sequence. Since the rubber sleeve 466 has a certain elasticity, the rubber sleeve 466 will expand after being filled with compressed air, thereby making its surface press tightly against the inner wall of the product to lock and fix the product. Moreover, the rubber sleeve 466 is a flexible material, which avoids causing wear to the surface of the product.

[0032] In addition, the expansion head 46 is fixed by connecting the threaded head 462 to the lower end of the connecting pipe 41 with a thread. When the expansion head 46 is damaged, it can be unscrewed and replaced with a new expansion head 46, which facilitates the maintenance and replacement of the expansion head 46 and improves the production efficiency of the equipment.

[0033] The working principle of this utility model is as follows: By moving the expansion claw 4 to the inside of the mold and inserting it into the inside of the ring-shaped product, the product is pushed out by the ejector rod and directly fitted onto the surface of the expansion claw 4. At this time, air is introduced into the expansion claw 4, causing the expansion head 46 to expand and press tightly against the inner wall of the product, fixing the product on the surface of the expansion claw 4, thus clamping and fixing the product. Then, the three-axis transmission component 1 and the pneumatic steering component 11 work together to move the product and place it on the surface of the conveyor belt, effectively improving the convenience and safety of product unloading. At the same time, by using a rubber sleeve 466 as the expansion component in the expansion head 46, the rubber sleeve 466 is a flexible product, avoiding scratches on the product surface and effectively improving the product production quality. Furthermore, the mounting frame 3 can slide back and forth inside the mounting base 2, allowing the front and rear length of the mounting frame 3 to be adjusted. At the same time, multiple sets of expansion claws 4 can slide back and forth inside the mounting frame 3, making the equipment suitable for ring-shaped products in different molds, improving the equipment's adaptability, and the adjustment process is relatively simple, thus improving the equipment's production efficiency.

Those skilled in the art should understand that this utility model is not limited to the above embodiments.
