Description

Technical Field

[0001] This utility model relates to the field of demolding technology, and in particular to a demolding device. Background Technology

[0002] Resin is a malleable material commonly used in oral medicine. It is often used in dental restoration, orthodontic and other surgeries. By taking an impression of the patient's teeth, resin materials are used to make custom-made resin teeth for the patient. During the process of making resin teeth, it is necessary to demold the resin teeth.

[0003] Most existing demolding methods involve manual demolding using pry bars. This method is inefficient, and the pry bars can easily deform the resin teeth, making the product unusable and resulting in a high scrap rate. Utility Model Content

[0004] The purpose of this invention is to address the problem that most existing demolding methods rely on manual prying, which is inefficient and can easily deform the resin teeth, rendering the product unusable and resulting in a high scrap rate. Therefore, this invention proposes a demolding device for antibacterial dental restorative composite resin materials.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a demolding device, comprising a base plate, an auxiliary device provided on the surface of the base plate, the auxiliary device comprising a vertical plate, the vertical plate being fixedly installed on the surface of the base plate, two vertical grooves being formed on the surface of the vertical plate, and sliding plates being slidably connected inside the two vertical grooves, a U-shaped frame and a placement box being fixedly installed at the ends of the two sliding plates away from the vertical grooves respectively, two first electric telescopic rods being fixedly installed on the inner surfaces of both sides of the placement box, a first clamping plate being fixedly installed at the output end of the first electric telescopic rod, a box door being connected to the surface of the placement box via a hinge, a threaded rod being rotatably connected between the inner walls of both ends of the U-shaped frame, a wheel being fixedly installed on the surface of the threaded rod, a sliding rod being fixedly installed between the inner walls of both ends of the U-shaped frame, two second clamping plates being threadedly connected to the surface of the threaded rod, a support plate being fixedly installed on the surface of the vertical plate, and second electric telescopic rods being fixedly installed on both sides of the support plate, the output end of the second electric telescopic rod being fixedly connected to the sliding plate.

[0006] The effect achieved by the above components is as follows: When demolding is required, the resin tooth mold to be demolded can be placed inside the placement box first. Then, the first electric telescopic rod drives the first clamping plate to clamp the lower end of the mold. Next, the second electric telescopic rod is activated, causing the second electric telescopic rod to drive the second clamping plate into the placement box. Then, the rotating wheel is rotated, causing the rotating wheel to drive the threaded rod to rotate. Since the threads on the surface of the threaded rod are opposite to each other with the rotating wheel as the center, when the threaded rod rotates, it can drive the two second clamping plates to clamp the upper end of the mold. Then, the two second electric telescopic rods are activated at the same time, causing the second electric telescopic rods to drive the two sliding plates to move in opposite directions inside the vertical groove, thereby separating the upper and lower parts of the mold and completing the demolding. This improves the demolding efficiency and avoids damage to the product caused by using a pry bar.

[0007] Preferably, the threads on the surface of the threaded rod are opposite to each other with the rotating wheel as the center, and the second clamping plate is slidably connected by the threaded rod and the slide rod.

[0008] The effect achieved by the above components is that the rotating wheel drives the threaded rod to rotate, and the threaded rod drives the second clamping plate to move on the surface of the slide rod.

[0009] Preferably, two hollow columns are fixedly installed on the surface of the base plate, and a support rod is slidably connected inside each of the two hollow columns. The end of the support rod away from the hollow column is fixedly connected to the placement box.

[0010] The effect achieved by the above components is that the hollow column and support rod restrict the movement direction of the placement box.

[0011] Preferably, the surfaces of the first clamping plate and the second clamping plate are provided with a plurality of protrusions, which increase the friction of the first clamping plate and the second clamping plate by means of the protrusions.

[0016] The effect achieved by the above components is that the screen can filter out residual molding powder, tooth powder and other molding materials on the resin teeth.

[0017] Preferably, a vertical plate is fixedly installed on the surface of the base plate, a motor is fixedly installed on the surface of the vertical plate, and a special-shaped gear is fixedly installed at the output end of the motor.

[0018] The effect achieved by the above components is that the motor drives the irregularly shaped gears to rotate.

[0030] Example 1, such as Figure 1-5As shown, a molding and demolding device for antibacterial dental restorative composite resin material includes a base plate 1. An auxiliary device 2 is provided on the surface of the base plate 1. The auxiliary device 2 includes a vertical plate 201, which is fixedly installed on the surface of the base plate 1. Two vertical grooves 202 are formed on the surface of the vertical plate 201. Slide plates 203 are slidably connected inside each of the two vertical grooves 202. A U-shaped frame 204 and a placement box 205 are respectively fixedly installed at the ends of the two slide plates 203 away from the vertical grooves 202. Two first electric telescopic... The first electric telescopic rod 206 has a first clamping plate 207 fixedly installed at its output end. A door 208 is hinged to the surface of the box 205. A threaded rod 213 is rotatably connected between the inner walls of both ends of the U-shaped frame 204. A wheel 214 is fixedly installed on the surface of the threaded rod 213. A sliding rod 215 is fixedly installed between the inner walls of both ends of the U-shaped frame 204. Two second clamping plates 216 are threadedly connected to the surface of the threaded rod 213. A support plate 209 is fixedly installed on the surface of the upright plate 201. Both sides of the support plate 209 are... A second electric telescopic rod 210 is fixedly installed. The output end of the second electric telescopic rod 210 is fixedly connected to the slide plate 203. When demolding is required, the resin tooth mold to be demolded can be placed inside the placement box 205 first. Then, the first electric telescopic rod 206 drives the first clamping plate 207 to clamp the lower end of the mold. Next, the second electric telescopic rod 210 is activated, causing the second electric telescopic rod 210 to drive the second clamping plate 216 into the placement box 205. Then, the rotating wheel 214 is rotated, causing the rotating wheel 214 to carry... When the threaded rod 213 rotates, the threads on the surface of the threaded rod 213 are opposite to each other with the rotating wheel 214 as the center. Therefore, when the threaded rod 213 rotates, it can drive the two second clamping plates 216 to clamp the upper end of the mold. Then, the two second electric telescopic rods 210 are activated at the same time, so that the second electric telescopic rods 210 drive the two sliding plates 203 to move in opposite directions inside the vertical groove 202, thereby separating the upper and lower parts of the mold and completing the demolding. This improves the demolding efficiency and avoids damage to the product caused by using a pry bar.

[0031] Reference Figure 1-5 As shown in this embodiment: the threads on the surface of the threaded rod 213 are opposite to each other with the rotating wheel 214 as the center. The second clamping plate 216 is slidably connected by the threaded rod 213 and the slide rod 215. The setting of the rotating wheel 214 has the effect of driving the threaded rod 213 to rotate. The setting of the threaded rod 213 has the effect of driving the second clamping plate 216 to move on the surface of the slide rod 215.

[0032] Reference Figure 1-2As shown in this embodiment: two hollow columns 211 are fixedly installed on the surface of the base plate 1. Support rods 212 are slidably connected inside the two hollow columns 211. The end of the support rod 212 away from the hollow column 211 is fixedly connected to the placement box 205. The arrangement of the hollow columns 211 and the support rods 212 has the effect of restricting the movement direction of the placement box 205.

[0033] Reference Figure 1-4 As shown in this embodiment: the surfaces of the first clamping plate 207 and the second clamping plate 216 are provided with multiple protrusions. The first clamping plate 207 and the second clamping plate 216 increase their friction by means of the protrusions. The protrusions improve the clamping effect of the first clamping plate 207 and the second clamping plate 216 on the mold.

[0034] Reference Figure 3-6 As shown in this embodiment: a reciprocating device 3 is provided on the surface of the base plate 1. The reciprocating device 3 includes a long groove 31, which is formed on the surface of the base plate 1. Two L-shaped plates 32 are slidably connected inside the long groove 31. A strip frame 33 is fixedly installed between the two L-shaped plates 32. The arrangement of the long groove 31 and the L-shaped plates 32 allows the strip frame 33 to move smoothly. Two L-shaped rods 34 are fixedly installed on the top surface of the strip frame 33. A placement frame 35 is fixedly installed at the end of the L-shaped rods 34 away from the strip frame 33. A screen 36 is provided on the bottom surface of the placement frame 35. The screen 36 serves to filter... To filter out residual molding powder, tooth powder, and other molding materials on the resin teeth, a vertical plate 37 is fixedly installed on the surface of the base plate 1, and a motor 38 is fixedly installed on the surface of the vertical plate 37. A special-shaped gear 39 is fixedly installed at the output end of the motor 38. The motor 38 drives the special-shaped gear 39 to rotate. Only one-third of the teeth on the surface of the special-shaped gear 39 are visible. The inner walls of the upper and lower ends of the strip frame 33 are provided with tooth-like structures. The special-shaped gear 39 and the tooth-like structures on the inner walls of the upper and lower ends of the strip frame 33 mesh with each other. The special-shaped gear 39 drives the strip frame 33 to move.

[0035] Working principle: When demolding is required, the resin tooth mold to be demolded can be placed inside the placement box 205. Then, the two first electric telescopic rods 206 are activated, which drive the two first clamping plates 207 to clamp the lower end of the mold. Next, one of the second electric telescopic rods 210 is activated, which drives one of the sliding plates 203 to move downward inside the vertical groove 202. The downward movement of the sliding plate 203 drives the U-shaped frame 204 to move downward. The downward movement of the U-shaped frame 204 ultimately drives the two second clamping plates 216 to move downward, so that the two second clamping plates 216... Entering the placement box 205, the rotating wheel 214 is then rotated. The rotation of the rotating wheel 214 drives the threaded rod 213 to rotate. Since the threads on the surface of the threaded rod 213 are opposite to each other with the rotating wheel 214 as the center, when the rotating wheel 214 drives the threaded rod 213 to rotate, the two second clamping plates 216 connected by threads on its surface move closer to each other on the surface of the slide rod 215. The two second clamping plates 216 clamp the upper end of the mold by moving closer to each other on the surface of the slide rod 215. Finally, the two second electric telescopic rods 210 are simultaneously activated, causing the second electric telescopic rods 210 to drive the two slide plates 203 to move in opposite directions inside the vertical groove 202. This causes the upper and lower parts of the mold to separate, thus completing the demolding process. The demolded resin dentures then fall into the placement box 205. This structure improves demolding efficiency and avoids damage to the product caused by using a pry bar. When demolding is complete and residual molding powder and other molding materials need to be cleaned from the resin dentures, first open the box door 208, then remove the resin dentures from the placement box 205 and place them inside the placement frame 35. Next, start the motor 38, which drives the shaped gear 39 to rotate. When the shaped gear 39 rotates and engages with the tooth-like structure on the lower inner wall surface of the strip frame 33, the strip frame 33 moves to the left. The leftward movement causes the L-shaped plate 32 to move to the left inside the long slot 31. At the same time, the leftward movement of the strip frame 33 causes the L-shaped rod 34 and the placement frame 35 to move to the left. When the shaped gear 39 rotates and meshes with the tooth-like structure on the upper inner wall surface of the strip frame 33, the strip frame 33 will eventually move to the right. As the motor 38 drives the shaped gear 39 to rotate continuously, the placement frame 35 moves back and forth left and right, causing the resin teeth inside to shake repeatedly left and right. This shakes the residual molding powder, tooth powder and other molding materials on the resin teeth through the screen 36 and out of the interior of the placement frame 35. Through the cooperation of the above structures, the purpose of cleaning the residual molding materials of the resin dentures is achieved.
