Description

Technical Field

[0001] This invention relates to the field of injection molding equipment technology, specifically to an injection molding device for producing plastic products. Background Technology

[0002] Injection molding equipment used in plastic product manufacturing typically refers to the key components of an injection molding machine. These components play a crucial role in the production process of plastic products. Injection molding equipment is one of the key pieces of equipment in plastic product manufacturing, widely used in various industries such as home appliances, automobiles, aerospace, instruments, defense, telecommunications, medical, construction, and daily necessities. It can mold plastic products with complex shapes, complex structures, high dimensional accuracy, and inserts, and has strong adaptability to processing various plastic materials.

[0003] Existing injection molding equipment for plastic product manufacturing only has one set of molds. When a company needs to produce two types of plastic products, it must change to the other mold after producing one type. Changing molds increases production preparation time and costs. Moreover, a single mold may wear out or become clogged after prolonged use, requiring downtime for cleaning, maintenance, or replacement. Since there is only one set of molds, production cannot be carried out during downtime, which not only affects production progress but may also delay customer delivery. Furthermore, before injection molding, the raw material remains static. During this static state, due to gravity or other factors, raw materials of different compositions or densities may be unevenly distributed within the equipment. This uneven distribution affects the flowability and filling properties of the raw material during injection molding, thus affecting the quality of the product. To address these issues, the inventor proposes an injection molding device for plastic product manufacturing. Summary of the Invention

[0038] By adopting the above technical solution, the motor 216 is operated, which causes the fixedly connected gear 215 to rotate, thereby causing the meshing gears 213 and 214 to rotate, and subsequently causing gears 212 and 210 to rotate in opposite directions.

[0039] The limiting component 3 includes a vertical plate 301, and the bottom end of the vertical plate 301 is fixedly connected to the base plate 1.

[0040] By adopting the above technical solution and setting two guide telescopic shafts 302, the fixedly connected square plate 303 can move horizontally under the action of the connecting plate 304 and the electric cylinder 305, thereby driving the U-shaped plate 306 to move horizontally.

[0041] An electric cylinder 305 is fixedly connected to the center of the side of the upright plate 301 away from the square plate 303.

[0042] By adopting the above technical solution, the electric cylinder 305 is activated, which causes the fixedly connected connecting plate 304 and square plate 303 to move horizontally, thereby achieving the effect of clamping and limiting the mold body 408 and driving the mold body 408 to move horizontally.

[0044] By adopting the above technical solution, two sliding limit plates 308 are set to drive the fixedly connected limit rod 309 to move horizontally, so as to achieve the effect of clamping and limiting the limit groove 411. The running motor 311 can make the fixedly connected double-headed screw 310 rotate.

[0045] The conversion component 4 includes a load-bearing plate 401, and the side end of the load-bearing plate 401 is fixedly connected to the base plate 1. A mounting cylinder 402 is rotatably connected to the top of the load-bearing plate 401 and the center of the side closest to the base plate 1. A rotating column 403 is slidably inserted into the center of the top of the mounting cylinder 402. A second motor 405 is fixedly connected to the bottom end of the load-bearing plate 401 and the center of the side. The output end of the second motor 405 passes through the load-bearing plate 401 and is fixedly connected to the mounting cylinder 402. An electric cylinder 404 is fixedly connected to the center of the bottom end inside the mounting cylinder 402. The output end of the second electric cylinder 404 is fixedly connected to the rotating column 403.

[0046] By adopting the above technical solution, the motor 405 can rotate the fixedly connected mounting cylinder 402, thereby achieving the effect of rotating the two mold bodies 408 by 180 degrees and completing the function of replacing the two mold bodies 408.

[0047] A load-bearing frame 406 is fixedly connected to the top of the rotating column 403. A placement groove 407 is symmetrically opened at the top of the load-bearing frame 406 near the center. A mold body 408 is symmetrically arranged at the top of the load-bearing frame 406 and at the placement groove 407. The two sets of mold bodies 408 are staggered and symmetrically distributed. A filling port 409 is opened at the top of the mold body 408 near the center. Limiting bodies 410 are symmetrically fixedly connected at the center of both ends of the mold body 408. Limiting grooves 411 are symmetrically opened at the center of both ends of the limiting body 410, and the limiting grooves 411 are adapted to the limiting rod 309.

[0048] By adopting the above technical solution, a load-bearing frame 406 and a placement groove 407 are set above the rotating column 403 to place two mold bodies 408. By opening an injection port 409 above the mold body 408, the plastic can be injected into the mold body 408 in conjunction with the telescopic tube 203.

[0049] Working Principle: In use, the plastic to be injected is first poured into the placement tank 201. Then, two sets of mold bodies 408 are placed on the placement groove 407. Subsequently, through the valve 202 and the telescopic tube 203, the plastic is injected into the mold body 408. While the plastic in the mold body 408 is cooling, the motor 216 is started, causing the fixedly connected gear 215 to rotate. This causes the two meshing gears 213 and 214 to rotate simultaneously in opposite directions, subsequently driving the fixedly connected shafts 209 and 211 to rotate. The rotation of shaft 211 causes gear 212 to drive the meshing gear 208 to rotate, and then the fixedly connected... The inner shaft 206 drives the mounting plate 219 and the two stirring rods 220 to stir in conjunction with the stirring blades. The rotating shaft 209 drives the gear 210 to rotate, and the gear 207 meshing with the gear 210 drives the sleeve shaft 205 to rotate. Then the mounting plate 217 and the two stirring rods 218, in conjunction with the stirring blades, mix in opposite directions, so as to achieve uniform stirring of the injection plastic inside the placement tank 201, preventing the injection plastic from standing still for a long time. This solves the problem that before injection molding, the raw material will remain in a static state, which may cause uneven distribution of raw materials with different compositions or densities in the device, affecting the quality of the product.

[0050] After completing the injection molding of a set of mold bodies 408, when it is necessary to replace other mold bodies 408 or to repair one set of mold bodies 408, firstly, the working motor 311 causes the fixedly connected double-headed screw 310 to rotate. Subsequently, the two threaded rotating limit plates 308 drive the limit rod 309 to move in opposite directions under the action of the slide groove 307. This allows the limit rod 309 to move out of the limit groove 411, thereby releasing the limiting work on the mold body 408. Then, the electric cylinder one 305 is started, causing the square plate 303 to move in the direction of the electric cylinder one 305, facilitating the subsequent rotation of the mold body 408. Then, the working electric cylinder two... 404, causing the fixedly connected rotating column 403 to drive the load-bearing frame 406 to rise, until the two sets of mold bodies 408 are higher than the upright plate 301. Then, the second working motor 405 can be started, causing the fixedly connected mounting cylinder 402 to drive the load-bearing frame 406 to rotate. After the two sets of mold bodies 408 have rotated 180 degrees, the second working cylinder 404 can be stopped. Then, the second working cylinder 404 can be started again until the rotated mold body 408 reaches the reset position. This solves the problem of frequently changing molds when producing two kinds of plastic products, which not only affects the production progress but may also cause delays in customer delivery.
