Description

Technical Field

[0001] The invention relates to the technical field of plastic molding, in particular to a high-temperature resistant plastic product molding device. Background Art

[0002] High-temperature resistant plastics have the advantages of high temperature resistance, flame retardancy, and good thermal stability. They are widely used in the fields of electronics, automobiles, machinery, and chemicals, and have broad application prospects. Usually, these plastic products are molded by injection molding, and the commonly used device is an injection molding machine. The working principle of an injection molding machine is similar to that of a syringe. It uses the thrust of a screw or plunger to inject the plasticized molten state, i.e., the viscous flow state, into a closed mold cavity. After solidification and shaping, the product is obtained.

[0015] Preferably, a square groove is provided on the inner wall of the circular ring, and a collecting groove is provided on the inner wall of the counterweight block. The interior of the collecting groove is communicated with the interior of the square groove, so as to store dust.

[0016] Preferably, the circular ring is a circular ring structure, and the fan blades are arc-shaped plate structures.

[0017] The present invention provides a high-temperature resistant plastic product molding device. It has the following beneficial effects:

[0018] 1. The present invention provides a rotating cooling mechanism, and the outer wall of the injection barrel is scraped by the rotation of the spiral scraper, so that a large amount of residue and dust adhered to the outer wall of the injection barrel when working in a high dust environment in the factory for a long time can be automatically scraped off, thereby avoiding the problem of heat dissipation imbalance of the original normal heat dissipation effect of the injection barrel due to the adhesion of a large amount of residue on the outer wall of the injection barrel, thereby ensuring the stability of the injection barrel during long-term operation, and through the spiral shape of the spiral scraper itself, during the rotation of the outer wall of the injection barrel, the residue and dust adhered to the outer wall of the injection barrel can be scraped off by the spiral shape, thereby avoiding the problem that the scraped residue and dust will accumulate and adhere to its outer wall when using a horizontal scraper to rotate.

[0019] 2. The present invention sets a rotating cooling mechanism. As the spiral scraper rotates continuously, the copper material of the spiral scraper will quickly absorb heat from the injection cylinder, and the external air will be heat exchanged and dissipated through the numerous heat dissipation grooves opened on the outer wall of the spiral scraper, thereby ensuring a stable heat dissipation effect on the injection cylinder. Without setting a large number of heat sinks, the rotating spiral scraper can achieve real-time contact with every part of the outer wall of the injection cylinder to absorb heat, and the total volume and mass of the spiral scraper are minimized while completing the heat dissipation evenly, avoiding the problems of a large number of heat sinks attached to the outer wall of the injection cylinder resulting in excessive volume, complicated transportation and assembly, and increased production costs, thereby reducing its total weight and making mobile transportation and production installation more convenient and quick.

[0020] 3. The present invention sets a dust collection mechanism, and when the spiral scraper rotates and the bristles do not rotate, the spiral scraper and the bristles rotate relative to each other, thereby completing the sufficient wiping and cleaning of the residues scraped and adhered to the outer wall of the injection barrel and the inner wall of the groove, further reducing the amount of residues with smaller particles adhering to the injection barrel and the amount of residues that cannot be scraped away by the gap between the inner wall of the spiral scraper and the injection barrel, and also improving the cleaning effect of the residues adhered to the side wall of the groove due to the rotational cleaning of the outer wall of the injection barrel. It also realizes the reduction of the workload of the staff and greatly reduces the number of times the cleaning tools are manually cleaned in a fully automatic manner.

[0021] 4. The present invention sets a dust collection mechanism, and the circular ring slides back and forth quickly on the inner wall of the arc plate through the elastic force of the elastic ropes on both sides, and drives the fan blades above to move the air back and forth quickly, so that the air flows to a certain extent, blowing away the surrounding high-temperature air to a certain extent, ensuring the stability of the heat dissipation effect.

[0022] 5. The present invention provides a dust collecting mechanism, and the roots of the bristles are continuously moved by the swing of the fixed rod, so that the bristles brush and clean the outer wall of the injection cylinder and the side walls of the groove while also moving the bristles. As the bristles rebound with their own elastic force, the residues adhering to themselves are shaken off onto the dust storage trough. The dust residues swept and shaken off by the injection cylinder and the bristles themselves are covered and collected by the dust storage trough, preventing the dust residues from scattering around and floating on the outer wall of the injection cylinder again, causing the problem of circulating pollution.

DETAILED DESCRIPTION Example 1

[0036] See also Figure 1-4 The present invention provides a technical solution: a high-temperature resistant plastic product molding device, including an extruder 5, a feeding barrel 1 is fixedly connected to the top of the extruder 5, a bracket 6 is fixedly connected to the bottom of the extruder 5, a bottom plate 7 is fixedly connected to the bottom of the bracket 6, the outer wall of the extruder 5 is fixedly connected to a hollow shaft motor 8, the outer wall of the extruder 5 is fixedly connected to an injection cylinder 2, the outer wall of the injection cylinder 2 is fixedly connected to the inner wall of the hollow shaft motor 8, and a rotating cooling mechanism 3 is provided on the outside of the injection cylinder 2;

[0037] The rotary cooling mechanism 3 comprises:

[0038] The spiral scraper 301 is a circular spirally wound structure. The outer wall of the spiral scraper 301 is fixedly connected to a threaded slide 302. The inner wall of the spiral scraper 301 is provided with a groove 303. One end of the spiral scraper 301 is fixedly connected to the output end of the hollow shaft motor 8. The outer wall of the spiral scraper 301 is provided with a heat dissipation groove 313. The spiral scraper 301 is driven by the hollow shaft motor 8 to rotate and scrape the surface of the injection barrel 2.

[0039] The slider 304 has a threaded groove 305 on its inner wall. The slider 304 is slidably connected to the outer wall of the threaded slider 302 through the threaded groove 305. The outer wall of the slider 304 is fixedly connected to a dust storage groove 314. The top of the dust storage groove 314 is fixedly connected to a brush 306. The slider 304 slides horizontally at the bottom of the spiral scraper 301.

[0040] In the process of pouring plastic granules into the feed barrel 1, heating and melting them at high temperature in the extruder 5, and then extruding them into the injection barrel 2 to another place for rapid cooling and molding, the high-temperature melted liquid plastic has always existed in the injection barrel 2, causing the inside of the injection barrel 2 to soften and deform under the long-term high-temperature injection molding work. At the same time, the hollow shaft motor 8 is started to drive the spiral scraper 301 on the outer wall of the injection barrel 2 to rotate, so that the outer wall of the injection barrel 2 is rotated and scraped by the rotation of the spiral scraper 301, and the outer wall of the injection barrel 2 is kept in the high dust environment of the factory for a long time. During operation, a large amount of residue and dust adhering to the outer wall of the injection tube 2 is automatically scraped off, thereby preventing the outer wall of the injection tube 2 from being adhered to a large amount of residue, which may cause the original normal heat dissipation effect of the injection tube 2 to be unbalanced, thereby ensuring the stability of the injection tube 2 during long-term operation. In addition, the spiral shape of the spiral scraper 301 itself can realize that during the rotation of the outer wall of the injection tube 2, the residue and dust adhering to the outer wall of the injection tube 2 can be scraped off along with the spiral shape, thereby avoiding the problem that the scraped residue and dust will accumulate and adhere to the outer wall when the horizontal scraper is used to rotate;

[0041] As the spiral scraper 301 rotates continuously, the copper material of the spiral scraper 301 quickly absorbs heat from the injection barrel 2, and the heat exchange and heat dissipation of the external air are carried out through the numerous heat dissipation grooves 313 provided on the outer wall of the spiral scraper 301, thereby ensuring a stable heat dissipation effect on the injection barrel 2. In addition, a large number of heat sinks are not provided, and the rotating spiral scraper 301 is used to realize real-time contact and heat absorption with every part of the outer wall of the injection barrel 2. When heat dissipation is completed uniformly, the total volume and mass of the spiral scraper 301 are minimized, and the problems of a large number of heat sinks attached to the outer wall of the injection barrel 2 resulting in excessive volume, complicated transportation and assembly, and increased production costs are avoided. The total weight is reduced, and mobile transportation and production installation are relatively convenient and fast. Example 2

[0042] See also Figure 1-9 Based on the first embodiment, the present invention provides a technical solution: the outer wall of the slider 304 is fixedly connected to the arc plate 311, the bottom of the arc plate 311 is fixedly connected to the counterweight block 315, and the inner wall of the arc plate 311 is slidably connected to the circular ring 309.

[0043] The outer wall of the slider 304 is fixedly connected to the rotating shaft 307 , and the outer wall of the rotating shaft 307 is rotatably connected to the roller 308 , and the outer wall of the roller 308 contacts the inner wall of the circular ring 309 .

[0044] The outer wall of the circular ring 309 is fixedly connected to the fan blade 312, the inner wall of the circular ring 309 is fixedly connected to the elastic rope 310, one end of the elastic rope 310 is fixedly connected to the outer wall of the arc plate 311, and the inner wall of the slider 304 is provided with a dust collection mechanism;

[0045] The slider 304 is moved to the right side of the spiral scraper 301 by the spiral shape of the threaded slider 302, and then returns to the left side again as the spiral scraper 301 reverses, completing the reciprocating wiping and cleaning of the outer wall of the spiral scraper 301, and accompanied by the dust storage groove 314 fixedly connected to the outer wall of the slider 304, which drives the dust storage groove 314 to be cleaned. The dust trough 314 moves synchronously with the bristles 306, so that the elastic bristles 306 continuously extend into the groove 303 to the surface of the injection barrel 2 and also contact the side wall of the groove 303. When the spiral scraper 301 rotates and the bristles 306 do not rotate, the spiral scraper 301 and the bristles 306 rotate relative to each other, thereby completing the full wiping and cleaning of the residues adhered to the outer wall of the injection barrel 2 and the inner wall of the groove 303 by scraping. This further reduces the amount of smaller particles of residue adhering to the injection barrel 2 and the amount of residue that cannot be scraped off by the gap between the inner wall of the spiral scraper 301 and the injection barrel 2. It also improves the cleaning effect of the residue adhered to the side wall of the groove 303 caused by the rotational cleaning of the outer wall of the injection barrel 2 by the groove 303, and also reduces the workload of the staff and greatly reduces the number of times the cleaning tool is manually cleaned in a fully automatic manner.

[0046] The slider 304 remains stationary at the bottom of the spiral scraper 301, and during the rotation of the spiral scraper 301, the roller 308 on the rotating shaft 307 is in contact with the outer wall of the spiral scraper 301, and is constantly toggled by the rotation of the spiral scraper 301, so that the roller 308 also rotates synchronously, and the rotation of the roller 308 drives the circular ring 309 to rotate through the contact with the circular ring 309. When the circular ring 309 rotates, it overcomes the elastic tension of the elastic rope 310, and when the roller 308 rolls to the heat dissipation groove 313 on the outer wall of the spiral scraper 301, the roller 308 is rotated. When the circular ring 309 is pulled back to its original position, the circular ring 309 slides back and forth rapidly on the inner wall of the curved plate 311 by the elastic force of the elastic ropes 310 on both sides, and drives the fan blades 312 above to move the air back and forth rapidly, so that the air flows to a certain extent and the surrounding high-temperature air is blown away to a certain extent, thereby ensuring the stability of the heat dissipation effect. Example 3

[0047] See also Figure 1-12 Based on the first and second embodiments, the present invention provides a technical solution: the dust collection mechanism includes an arc groove 402, the arc groove 402 is opened on the inner wall of the slider 304, the inner wall of the arc groove 402 is slidably connected to the sliding plate 401, and the outer wall of the sliding plate 401 is fixedly connected to the arc rod A403.

[0048] The outer wall of the arc-shaped rod A403 is fixedly connected to a fixing rod 404 , and one end of the fixing rod 404 is fixedly connected to an arc-shaped rod B405 .

[0049] A square groove 406 is formed on the inner wall of the circular ring 309 , and a collecting groove 407 is formed on the inner wall of the counterweight block 315 . The interior of the collecting groove 407 is communicated with the interior of the square groove 406 .

[0050] The circular ring 309 is a circular ring structure, and the fan blades 312 are arc-shaped plate structures;

[0051] The square groove 406 and the collecting groove 407 are provided to minimize the occurrence of dust being trapped at the bottom of the circular ring 309. When the roller 308 rolls on the circular ring 309, the obstruction between the roller 308 and the circular ring 309 is reduced, thereby improving the stability of the rotation of the circular ring 309 and preventing dust accumulation and the occurrence of blockage between the roller 308 and the circular ring 309.

[0052] The bottom of the sliding plate 401 is fixedly connected to the circular ring 309 on the inner wall of the arc plate 311, so when the circular ring 309 swings back and forth, the sliding plate 401 will also swing back and forth and slide on the inner wall of the arc groove 402. As the sliding plate 401 swings and slides, the fixed rod 404 on the arc rod A403 is controlled to swing synchronously. The swing of the fixed rod 404 continuously moves the root of the bristles 306, so that the bristles 306 brush and clean the outer wall of the injection cylinder 2 and the side wall of the groove 303, and also move the bristles 306. As the bristles 306 rebound with their own elastic force, the residue adhered to themselves is shaken off onto the dust storage groove 314. The dust residue swept and shaken off by the injection cylinder 2 and the bristles 306 themselves is covered and collected by the dust storage groove 314 to prevent the dust residue from scattering around and floating on the outer wall of the injection cylinder 2 again, causing the problem of circulating pollution.
