Description

Technical Field

[0001] The utility model relates to the technical field of nylon wheels, in particular to a molding device for producing nylon wheels. Background Art

[0002] Nylon wheels refer to wheels or rollers made of nylon materials. Nylon is a synthetic polymer that is lightweight, wear-resistant, corrosion-resistant and strong, so it is widely used to manufacture various mechanical parts, including wheels. During the production process of some nylon wheels, the melted raw materials are poured into the prepared mold, and then the mold is placed in a centrifuge for centrifugal rotation and molding. After cooling and molding, the nylon wheel is taken out of the mold to complete the production.

[0003] After searching, a Chinese patent with authorization announcement number CN217346329U discloses a nylon wheel molding device, which points out the problem that the nylon wheel molding device in the prior art is inconvenient to clamp and fix the placed mold, and is inconvenient to dissipate heat and cool the casting mold, thereby reducing work efficiency, and makes improvements. The improvement method is as follows: "By arranging a clamping mechanism on the placement box, it is convenient to clamp and fix the mold placed inside the placement box, so that the mold placement is more stable and the quality of mold molding is improved. By injecting cooling water into the inside of the placement box and using the box cover to cover and seal the top of the placement box, the mold inside the placement box is dissipated and cooled, the cooling time is shortened, and its work efficiency is effectively improved."

[0004] Although the device has certain improvements, it still has the following shortcomings. For example, the shape of the mold is not fixed, and the clamp used in the device is a flat plate with a flat cross-section. Therefore, when clamping a cylindrical or other irregularly shaped mold, there are fewer contact points between the clamp and the mold, and the mold is easy to loosen, which may affect the product processing quality.

[0005] At the same time, the common placement box and the box cover are sealed only by a sealing ring and a sealing groove. After long-term use, the sealing ring will age and loosen, resulting in the inability to fit tightly against the inner wall of the sealing groove when plugged into the sealing groove, thereby affecting the sealing effect and causing the coolant to easily leak out from the gap between the placement box and the box cover during processing.

The round rod 44 is fixedly connected to a non-center position on the front surface of the turntable 41.

[0040] Reference Figure 1 and Figure 7 The upper surface of the placement box 51 is rotatably connected with a box cover 52, and the lower surface of the box cover 52 is fixedly connected with a rubber ring 53 for sealing. The upper surface of the box cover 52 is fixedly connected with a handle 55 for easy grasping. After unlocking, the box cover 52 can be opened by grasping the handle 55. A buckle 54 is provided on the left surface of the placement box 51. The buckle 54 is used to lock the placement box 51 and the box cover 52. The buckle 54 is divided into two parts, one part is fixed on the left surface of the placement box 51, and the other part is fixed on the left surface of the box cover 52. An annular groove 501 is provided on the upper surface of the placement box 51, and the inner wall of the annular groove 501 is elastically connected with a rubber ring 53 for sealing through a compression spring 57. The rubber ring 56, the rubber ring 53 and the rubber ring 56 can seal the gap between the placement box 51 and the box cover 52. The rubber ring 56 is slidably connected to the inner wall of the annular groove 501. The rubber ring 56 slides up and down along the inner wall of the annular groove 501. The rubber ring 53 is inserted into the inner wall of the annular groove 501. When the rubber ring 53 is inserted into the annular groove 501, it will squeeze the rubber ring 56.

One end of the compression spring 57 is fixedly connected to the lower surface of the rubber ring 56, and the other end of the compression spring 57 is fixedly connected to the inner wall of the bottom end of the annular groove 501. When the rubber ring 56 moves downward, it will squeeze the compression spring 57 to generate a reaction force.

[0041] Reference Figure 2 and Figure 7 The drainage component includes a water outlet pipe 61, and the coolant will be discharged from the water outlet pipe 61. A valve 62 is set in the middle section of the water outlet pipe 61. The valve 62 can control the switch of the coolant discharge. The water outlet pipe 61 passes through and is fixedly connected to the rear surface of the placement box 51.

[0042] Working principle: When in use, first fill the nylon wheel raw material into the mold, then place the mold in the placement box 51, then grab the round rod 44 to drive the turntable 41 to rotate, the rotating turntable 41 will drive the two-way threaded rod 42 to rotate, and the two-way threaded rod 42 will drive the two sets of slides 43 to move toward the center of the two-way threaded rod 42, and the slides 43 will drive the arc plate 46, the clamping block 1 47 and the clamping block 2 48 to move synchronously. When the clamping block 2 48 contacts the mold, continue to rotate the round rod 44, the clamping block 2 48 will squeeze the mold, and the reaction force of the squeezing will make Clamp block 2 48 will slide along slide groove 2 402, and will cause clamp block 1 47 to slide along slide groove 1 401, and the sliding clamp block 2 48 and clamp block 1 47 will gradually wrap the mold. When clamp block 2 48 and clamp block 1 47 wrap the mold, release the round rod 44, the turntable 41 and the two-way threaded rod 42 will stop rotating, and the slide plate 43, the arc plate 46, clamp block 1 47 and clamp block 2 48 will also stop moving, which can keep the device stable. At this time, clamp block 2 48 and clamp block 1 47 have more contact points with the mold, which can ensure stability during clamping.

[0043] After the mold is fixed, pour the coolant into the placement box 51 and grasp the handle 55 to close the box cover 52. When the box cover 52 is closed, the rubber ring 53 will be plugged into the annular groove 501, and the rubber ring 53 will squeeze the rubber ring 56 to move the rubber ring 56 downward. The rubber ring 56 moving downward will squeeze the compression spring 57 to generate a reaction force. The reaction force of the compression spring 57 will push the rubber ring 56 to move upward and fit the rubber ring 53 to ensure the sealing of the device. Then lock the buckle 54, and start the motor 3 to start centrifugal molding of the nylon wheel. The coolant inside the placement box 51 can speed up the molding speed.

[0044] After the nylon wheel is formed, the motor 3 is turned off, and then the valve 62 is opened, and the coolant inside the placement box 51 will be discharged from the outlet pipe 61, and the discharged coolant will be collected for subsequent use.

[0045] Then unlock the buckle 54 and grasp the handle 55 to open the box cover 52. After the box cover 52 is opened, grasp the round rod 44 and rotate it in the opposite direction. The round rod 44 rotating in the opposite direction will drive the turntable 41 and the two-way threaded rod 42 to rotate in the opposite direction synchronously. When the two-way threaded rod 42 rotates in the opposite direction, it will drive the two sets of slide plates 43, the arc plate 46, the clamping block 1 47 and the clamping block 2 48 to disperse, release the clamping of the mold, and then take out the mold, and take out the nylon wheel formed in the mold to complete the molding work.
