Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an automatic mold adjustment device for injection molding machines. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection machines, are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. Injection molding machines have automatic mold adjustment devices that can adjust the position of the mold. In the current technology, when operators use the automatic mold adjustment device of the injection molding machine, the adjustment distance and position of the mold are not intuitive enough, which can easily cause deviations in mold adjustment and make the accuracy of mold adjustment less than ideal.

[0003] For example, patent publication number CN205498005U describes a mold adjustment device for an injection molding machine. It includes a mold-locking tail plate and a large gear, an adjustment gear, a hydraulic motor, a motor base, and a guide rod disposed on the tail plate. The hydraulic motor is mounted on the tail plate via a motor base. The hydraulic motor meshes with the large gear via a hydraulic motor gear. The large gear is fixed at the center of the tail plate. Adjustment gears are located at each of the four corners of the tail plate, meshing with the large gear. The guide rod is fixed to the tail plate via the adjustment gear. This invention has a simple structure and reasonable design. The hydraulic motor drives the adjustment gears at the four corners of the tail plate to rotate via the large gear, thereby driving the guide rod to rotate, thus automatically adjusting the position of the injection mold. The adjustment method is flexible and the adjustment accuracy is high, further improving the precision of the injection molded parts and increasing injection efficiency. However, when using the automatic mold adjustment device of the injection molding machine, the operator cannot intuitively determine the adjustment distance and position of the mold, which can easily lead to deviations in mold adjustment and make the accuracy of mold adjustment less than ideal.

The operator can directly know the mold adjustment distance, thereby effectively improving the accuracy of mold adjustment.

[0022] The mold adjustment mechanism 2 includes multiple adjusting screws 201 and an observation seat 207. The observation seat 207 is located on one side of a tie post 1 and is fixedly mounted on the mold adjustment base 3, ensuring its stability. The multiple adjusting screws 201 are respectively fixedly connected to the multiple tie posts 1. Adjusting nuts 202 are threaded onto the external parts of the multiple adjusting screws 201, allowing the adjusting nuts 202 to rotate and move along the adjusting screws 201 to adjust the mold. Adjusting gears 20 are fixedly connected to the adjusting nuts 202. 3. A gear ring 204 is provided between multiple adjusting gears 203. A drive gear 205 is provided on one side of the gear ring 204. Multiple support frames are fixedly installed on the mold adjustment base 3. The multiple adjusting gears 203 and drive gears 205 are respectively installed inside the multiple support frames, so that they can support the adjusting gears 203 and drive gears 205. An adjusting motor 206 is fixedly connected to the end of the drive gear 205. A viewing window 208 is provided on the viewing base 207. An indicator needle 209 is provided on the viewing window 208. A driven motor is rotatably connected inside the viewing base 207. Roller 210, driven roller 210 has a spring 211 installed at one end to keep the scale 213 taut at all times for easy reading. Driven roller 212 is located at the bottom of driven roller 210, and scale 213 is located between driven roller 212 and driven roller 210. Driven bevel gear 214 is fixedly connected to the end of driven roller 212, and drive bevel gear 215 is located on one side of driven bevel gear 214. A traveling wheel 216 is drivenly connected to the end of drive bevel gear 215, and both the end of traveling wheel 216 and the end of drive bevel gear 215 are fixed. A synchronous pulley is connected, and a synchronous belt is sleeved between the two synchronous pulleys. A tension pulley is provided on one side of the synchronous belt. The traveling wheel 216 is connected to the driving bevel gear 215 through the synchronous pulley and the synchronous belt, so that the traveling wheel 216 can rotate synchronously with the driving bevel gear 215. The traveling wheel 216 is provided with a rubber sleeve, which can effectively increase the friction and ensure that the traveling wheel 216 can rotate. The traveling wheel 216 abuts against the surface of a tie column 1, so that the traveling wheel 216 can roll along the surface of the tie column 1 when the mold adjusting base 3 moves.

[0023] Please see Figure 1 and Figure 4The lubrication mechanism 4 includes an oil tank 401. An oil pump 402 is fixedly connected to the top of the oil tank 401. An oil nozzle 403 is installed at the end of the oil pump 402. A return oil pump 404 is provided on one side of the oil tank 401. A return oil pipe is connected to the end of the return oil pump 404. An oil receiving pan 405 is connected to the end of the return oil pipe. An oil return port is opened inside the oil receiving pan 405. A one-way valve 406 is installed inside the oil return port to prevent the lubricating oil from flowing back. The oil return port is connected to the return oil pipe. The lubricating oil in the oil tank 401 can be sent to the oil nozzle 403 by the oil pump 402. The oil nozzle 403 sprays the lubricating oil onto the gear ring 204, which can play a good lubricating role for the gear. The oil receiving pan 405 collects the dripping lubricating oil, and the return oil pump 404 sends the lubricating oil in the oil receiving pan 405 back into the oil tank 401 for recycling.

[0024] During operation, the adjusting motor 206 drives the drive gear 205 to rotate, which in turn drives the gear ring 204 to rotate. The gear ring 204 then drives multiple adjusting gears 203 to rotate, which in turn drives the adjusting nut 202 to rotate. This causes the adjusting nut 202 to move on the adjusting screw 201. The movement of the adjusting nut 202 moves the mold base 3, which in turn moves the traveling wheel 216 along the guide column 1. The rolling of the traveling wheel 216 then drives the drive bevel gear 215 to rotate. The rotation of gear 215 drives the driven bevel gear 214 to rotate, which in turn drives the drive roller 212 to rotate. The drive roller 212, in conjunction with the driven roller 210, moves the scale 213. The spring 211 keeps the scale 213 taut. The indicator needle 209 indicates the scale on the scale 213 through the viewing window 208, displaying the mold adjustment distance. This makes mold adjustment more intuitive, allowing staff to directly know the mold adjustment distance and effectively improve the accuracy of mold adjustment.
