[0002] A plastic medical consumable injection molding device, with announcement number CN217021260U, includes a mounting platform, a mold mechanism, and a material conveying mechanism. The mold mechanism includes a mounting plate vertically fixed to one end of the mounting platform, a motor housing fixedly connected to the rear side of the mounting plate, and a motor horizontally fixedly connected inside the motor housing. This plastic medical consumable injection molding device, through the mold mechanism, uses a motor to drive a half-gear, which in turn drives multiple gear structures to control the regular separation and merging of the injection molds. When two injection molds merge, the injection molding device injects liquid plastic into them. After the plastic cools and solidifies, the two injection molds separate, and the finished product falls off. The two injection molds then merge again, repeating this process. This automates the mold merging and separation, improving production efficiency and the practicality of the device.

[0003] When the above-mentioned device is in use, the molded product may stick to the injection cavity when the two injection molds are separated. The above-mentioned equipment is an automated continuous production. If the product sticks to the mold and is not cleaned in time, it will affect the molding quality of the next product or even all subsequent products, thus increasing the scrap rate. Therefore, there is a need for an injection molding device for medical consumables to meet people's needs. Utility Model Content

The injection molding machine body 1 has a limiting groove 309, which is opened vertically. A second protrusion 305 is slidably installed in the limiting groove 309. The molding device 2 includes a first motor 200, which is fixedly installed in the injection molding machine body 1. A first half gear 201 is fixedly installed on the output end of the first motor 200. A first rotating shaft 202 is rotatably installed on the injection molding machine body 1, which is installed below the first half gear 201. A first transmission gear 203 is fixedly installed on the first rotating shaft 202, and the first transmission gear 203 meshes with the first half gear 201. A second transmission gear 204 is fixedly installed on the first rotating shaft 202. A second rotating shaft 206 is installed on one side of the first rotating shaft 202. A second shaft 206 is rotatably mounted on the injection molding machine body 1. A third transmission gear 207 is fixedly mounted on the second shaft 206, and the second transmission gear 204 meshes with the third transmission gear 207. A first main transmission wheel 205 is fixedly mounted on the first shaft 202. A third shaft 209 is mounted on the side of the first shaft 202 away from the second shaft 206, and the third shaft 209 is rotatably mounted on the injection molding machine body 1. A first driven transmission gear 210 is fixedly mounted on the third shaft 209, and a first connecting rod 211 is rotatably mounted on the first driven transmission gear 210. A second main transmission wheel 208 is fixedly mounted on the second shaft 206. A fourth shaft 212 is mounted on the side of the second shaft 206 away from the first shaft 202, and the fourth shaft 212 is rotatably mounted on... On the main body 1 of the injection molding machine, a second driven gear 213 is fixedly mounted on the fourth rotating shaft 212. A second connecting rod 214 is rotatably mounted on the second driven gear 213. A pair of molding blocks 215 are mounted on the main body 1 of the injection molding machine. The other ends of the first connecting rod 211 and the second connecting rod 214 are rotatably mounted on the molding blocks 215. Two third main drive wheels 300 are fixedly mounted on the third rotating shaft 209 and the fourth rotating shaft 212, respectively. A molding groove 216 is opened on the molding block 215. An ejector bar 306 is installed below the molding groove 216. The structure and motion principle of the molding device 2 of this device are the same as those of the molding structure in CN217021260U. The first main drive wheel 205 and the first driven gear 210 are connected by a belt for transmission.The second main drive wheel 208 and the second driven drive gear 213 are connected by a belt. When the molding device 2 is working, the two molding blocks 215 repeatedly approach and move away under the drive of the first half gear 201. Only half of the first half gear 201 has teeth, and its number of teeth is equal to that of the first drive gear 203 and the third drive gear 207. Therefore, when the teeth on the first half gear 201 mesh with the first drive gear 203, they can drive it to rotate a full revolution. The first drive gear 203 drives the first driven drive gear 210 to rotate a full revolution through the first main drive wheel 205. The third transmission gear 207 meshes in the opposite direction to the first transmission gear 203. The third transmission gear 207 drives the second driven transmission gear 213 to rotate one revolution via the second main transmission wheel 208. When the first driven transmission gear 210 rotates, it drives one side of the forming block 215 to move left and right via the first connecting rod 211. The second driven transmission gear 213 drives the forming block 215 to move via the second connecting rod 214. When the toothless part of the first half gear 201 rotates onto the first transmission gear 203, the first transmission gear 203 will not be driven to continue rotating. At this time, the third... With the first drive gear 210 and the second drive gear 213 remaining stationary, the two molding blocks 215 approach and come into contact with each other. As the molding blocks 215 approach, the injection molding device on the main body 1 injects raw material into the molding groove 216. When the molding blocks 215 separate, under the rotation of the third rotating shaft 209 and the fourth rotating shaft 212, the third main drive wheel 300 moves via the belt to the third driven wheel 302. The third driven wheel 302 rotates upward at this time, and as it moves upward, it pushes the ejector bar 306 upward via the connecting rod 304. The ejector bar 306 moves upward and cleans the forming groove 216 via the ejector plate 307 to prevent product residue inside. When the connection points of the first connecting rod 211 and the second connecting rod 214 with the first driven gear 210 and the second driven gear 213 are at the left or right ends of the first driven gear 210 and the second driven gear 213, the first protrusion 303 on the third driven wheel 302 should be located at the upper or lower ends, thus ensuring that when the forming block 215 moves left and right reciprocatingly, the ejector bar 306 moves up and down reciprocatingly under the limitation of the limiting groove 309.

[0026] Example 2: Figure 5In order to collect the product and prevent it from splashing into the mounting slot inside the device, the collection box 4 has a slot 5. The ejector bar 306 and the second protrusion 305 are slidably installed in the slot 5. A baffle 308 is fixedly installed on the injection molding machine body 1. In order to prevent the product from splashing into the injection molding machine body 1 when cleaning the molding slot 216, the baffle 308 is fixedly set on one side of the molding block 215. The baffle 308 can block the molding block 215 and the injection molding machine body 1, and can prevent the product from being pushed into the injection molding machine body 1 by the ejector bar 306 during ejection. The collection box 4 can collect the product. The slot 5 on the collection box 4 can not affect the normal movement of the ejector bar 306 and the second protrusion 305. The remaining features are the same as in Embodiment 1.

[0027] The working principle is as follows: The structure and motion principle of the molding device 2 in this device are the same as those in CN217021260U. The first main drive wheel 205 is connected to the first driven gear 210 via a belt, and the second main drive wheel 208 is connected to the second driven gear 213 via a belt. When the molding device 2 is working, the two molding blocks 215 repeatedly approach and move away under the drive of the first half gear 201. Only half of the first half gear 201 has teeth, and its number of teeth is equal to that of the first drive gear 203 and the third drive gear 207. Therefore, when the teeth on the first half gear 201 mesh with the first drive gear 203, it can drive the first drive gear 203 to rotate a full revolution. The first drive gear 203, through the first main drive wheel 205... The driving wheel 205 drives the first driven gear 210 to rotate one revolution. The third driven gear 207 meshes in the opposite direction to the first driven gear 203. The third driven gear 207 drives the second driven gear 213 to rotate one revolution via the second main drive wheel 208. When the first driven gear 210 rotates, it drives one side of the forming block 215 to move left and right via the first connecting rod 211. The second driven gear 213 drives the forming block 215 to move via the second connecting rod 214. When the toothless part of the first half gear 201 rotates onto the first driven gear 203, the first driven gear 203 will not be driven to continue rotating. At this time, the first driven gear 210 and the second driven gear 213 also remain stationary. The two forming blocks 215 The molding blocks 215 come close together. When they are close, the injection molding device on the main body 1 of the injection molding machine injects raw material into the molding groove 216. When the molding blocks 215 separate, under the rotation of the third rotating shaft 209 and the fourth rotating shaft 212, the third main drive wheel 300 moves through the belt to the third driven wheel 302. The third driven wheel 302 rotates upward at this time. When the third driven wheel 302 moves upward, it pushes the ejector bar 306 upward through the connecting rod 304. The ejector bar 306 moves upward and cleans the molding groove 216 through the ejector plate 307 to prevent product residue inside. When the connection point of the first connecting rod 211 and the second connecting rod 214 with the first driven gear 210 and the second driven gear 213 is at the first driven gear... When the third driven wheel 302 is at the left or right end of the wheel 210 and the second driven gear 213, the first protrusion 303 on the third driven wheel 302 should be at the upper or lower end, so as to ensure that when the molding block 215 moves back and forth, the ejector bar 306 moves back and forth under the limit of the limiting groove 309. In order to prevent the product from splashing into the injection molding machine body 1 when cleaning the molding groove 216, a baffle 308 is fixedly set on one side of the molding block 215. The baffle 308 can block the molding block 215 and the injection molding machine body 1, and can prevent the product from being pushed into the injection molding machine body 1 by the ejector bar 306 during ejection. The collection box 4 can collect the product, and the slot 5 on the collection box 4 can not affect the normal movement of the ejector bar 306 and the second protrusion 305.
