Description

Technical Field

[0001] The invention relates to the technical field of injection molding machines, in particular to an injection molding machine. Background Art

[0002] An injection molding machine is a device that uses a mold to make plastic products from thermoplastics. The hopper of the injection molding machine is installed on the barrel, and a heating ring is provided on the outside of the barrel. When the injection molding machine is working, the temperature at the channel of the hopper is high, which can easily cause the plastic particles flowing into the hopper to melt and form lumps, causing the hopper to be blocked and affecting the normal operation of the injection molding machine. Therefore, it is necessary to cool the side wall of the hopper to avoid clogging of the hopper.

[0003] In the prior art, most of the cooling water pipes are wound around the outside of the hopper, and the hopper is cooled by the cooling water. The cooling water in the pipe cools the hopper and then flows back to the water tank. The cooling water in the water tank is then cooled by the heat sink to achieve the recycling of the cooling water. However, the heat sink has a poor effect on cooling the cooling water in the water tank, which affects the recycling of the cooling water. Summary of the invention

[0004] The present application provides an injection molding machine, which has a relatively good cooling and heat dissipation effect on the returning cooling water, so that the returning cooling water can be better recycled.

[0005] The present application provides an injection molding machine, which adopts the following technical solution:

[0006] An injection molding machine comprises an injection molding machine body; a hopper is detachably mounted on the top of the injection molding machine body, and a water tank is fixedly connected to the side wall of the injection molding machine body; the hopper is communicated with the inside of the barrel of the injection molding machine body, and a cooling channel is arranged inside the side wall of the hopper; a conveying mechanism for conveying cooling water is arranged on the injection molding machine body; the conveying mechanism is communicated with the inside of the water tank, and the conveying mechanism is communicated with the inside of the cooling channel; a return pipe is fixedly connected to the outer wall of the water tank; the return pipe is connected to the outlet of the cooling channel; a motor is mounted on the top of the water tank; a first rotating shaft is fixedly connected to the output end of the motor; a fan blade is fixedly connected to the end of the first rotating shaft; a concave plate is fixedly connected to the inner wall on the same side of the water tank and the return pipe; a diversion mechanism for diverting cooling water is arranged inside the concave plate; the outlet of the return pipe faces the concave plate.

[0007] By adopting the above technical scheme, the cooling treatment of the cooling water returning to the water tank is achieved. When the hopper is cooled, the cooling water in the water tank is transported to the cooling channel through the conveying mechanism, and the hopper is cooled by the cooling water to prevent the material from melting and clogging the hopper. The cooling water in the cooling channel flows onto the concave plate through the reflux pipe, and the motor is started. The motor drives the first rotating shaft and the fan blades to rotate, and the cooling water on the concave plate and the cooling water in the water tank are blown and cooled by the fan blades, and the cooling water on the concave plate is diverted by the diversion mechanism, so that the cooling water can be better recycled.

[0008] Preferably, the diversion mechanism includes a pair of baffles, a pair of rotating shafts and a plurality of straight plates; a pair of the baffles are fixedly connected to the inner wall of the concave plate, and the baffles and the inner wall of the concave plate are arranged at an inclination; a pair of the rotating shafts are rotatably connected to the top of the concave plate; a plurality of the straight plates are fixedly connected to the outer wall of the rotating shaft, and a plurality of through holes are provided on the straight plates; a cam is fixedly connected to the end of the rotating shaft that does not contact the concave plate; a groove is provided on the inner wall of the concave plate close to the straight plate; a jet assembly for cooling cooling water is provided inside the groove; and the cam drives the jet assembly to move.

[0009] By adopting the above technical scheme, the cooling water falling on the concave plate is heat-dissipated, and the cooling water in the cooling channel falls onto the concave plate through the reflux pipe. The baffles staggered on the concave plate extend the time for the cooling water to flow on the concave plate, thereby extending the contact time between the cooling water and the air, so that the fan blades can fully blow air to cool the cooling water. When the cooling water flows along the baffles to the straight plate, the cooling water drives the rotating shaft and the straight plate to rotate. When the cooling water flows through the through hole, it is diverted, making it easier for the cooling water to dissipate heat. During the rotation of the rotating shaft, the cam drives the jet assembly to spray, thereby achieving further heat dissipation of the cooling water.

[0010] Preferably, the jet assembly includes a pressure plate and a jet nozzle; the pressure plate is slidably connected inside the groove, and a curved surface cooperating with the cam is provided on the side wall of the pressure plate close to the cam, and the side wall of the pressure plate away from the cam is connected to the inner wall of the groove through a spring; the jet nozzle is fixed to the inner wall of the concave plate; an airbag is provided inside the groove; the airbag is connected to the inside of the jet nozzle, and the airbag is in contact with the side wall of the pressure plate close to the spring.

[0011] By adopting the above technical solution, the cooling water is jetted to dissipate heat. The rotation of the rotating shaft drives the cam to rotate. During the rotation of the cam, the pressure plate is pushed to squeeze the airbag by cooperating with the arc surface on the side wall of the pressure plate. The airbag is pressurized to spray air, so that the gas inside the airbag is ejected from the jet nozzle. The gas ejected from the jet nozzle further dissipates the heat of the cooling water on the concave plate. The cam and the pressure plate are arranged to achieve cyclic extrusion.

[0012] Preferably, the conveying mechanism includes a water pump, a water inlet pipe and a water outlet pipe; the water pump is fixedly connected to the top of the injection molding machine body; the water inlet pipe is connected to the inside of the water tank, and the end of the water inlet pipe away from the water tank is connected to the input end of the water pump; the water outlet pipe is connected to the inlet of the cooling channel, and the end of the water outlet pipe away from the hopper is connected to the output end of the water pump.

[0013] By adopting the above technical solution, cooling water is transported. When the hopper is cooled, the cooling water inside the water tank is transported to the water outlet pipe through the water inlet pipe by a water pump, and then the cooling water is transported to the cooling channel. When the cooling water flows in the cooling channel, the heat is carried away by the cooling water in the form of heat conduction, thereby achieving cooling of the hopper.

[0014] Preferably, a tumbling mechanism for stirring cooling water is provided inside the water tank; the tumbling mechanism is driven by the first rotating shaft, and the tumbling mechanism includes a second rotating shaft, a third rotating shaft, a tipping bucket block and a first belt; the second rotating shaft is rotatably connected to the outer wall of the water tank, and the end of the second rotating shaft close to the first rotating shaft is fixedly connected to the first pulley; the middle of the first rotating shaft is fixedly connected to the second pulley; the first belt sleeve is arranged on the outside of the first pulley and the second pulley; the end of the second rotating shaft away from the first pulley is fixedly connected to the first bevel gear; the third rotating shaft is rotatably connected to the inner wall of the water tank, and the end of the third rotating shaft close to the first bevel gear extends out of the water tank, and the end of the third rotating shaft extending out of the water tank is fixedly connected to the second bevel gear; the first bevel gear is meshed with the second bevel gear; the tipping bucket block is fixed to the outer wall of the third rotating shaft.

[0015] By adopting the above technical scheme, the cooling water in the water tank is promoted to tumble, and the heat dissipation of the cooling water is accelerated. When the motor drives the first shaft and the second pulley to rotate, the first pulley rotates under the drive of the first belt, thereby driving the second shaft and the first bevel gear to rotate, and the first bevel gear is meshed with the second bevel gear to drive the third shaft and the tipping bucket block to rotate. During the rotation of the tipping bucket block, the cooling water is collected and sprinkled, which accelerates the heat dissipation of the cooling water, allowing the fan to better dissipate heat and cool down the cooling water. By setting up multiple tipping bucket blocks, the sprinkling effect of the cooling water is better, and the cooling of the cooling water is accelerated.

[0016] Preferably, a stirring mechanism for stirring the cooling water is arranged inside the water tank; the stirring mechanism is driven by a third rotating shaft, and the stirring mechanism includes a fourth rotating shaft, a stirring plate and a second belt; the fourth rotating shaft is rotatably connected to the inner wall of the water tank, the end of the fourth rotating shaft close to the second bevel gear extends out of the water tank, and the end of the fourth rotating shaft extending out of the water tank is fixedly connected to the third pulley; the end of the third rotating shaft extending out of the water tank is fixedly connected to the fourth pulley; the second belt is arranged on the outside of the third pulley and the fourth pulley; the stirring plate is fixedly connected to the outer wall of the fourth rotating shaft.

[0017] By adopting the above technical solution, the movement of cooling water is promoted and the heat dissipation is accelerated; the fourth shaft is driven to rotate by the third shaft under the action of the second belt, and the stirring plate is driven to rotate during the rotation of the fourth shaft. During the rotation of the stirring plate, the cooling water at the bottom of the water tank is rolled, which promotes the movement of cooling water and accelerates the heat dissipation of cooling water.

[0018] Preferably, a plurality of heat dissipation holes are provided at the bottom of the concave plate.

[0019] By adopting the above technical solution, the heat in the water tank is easily dissipated. By setting the heat dissipation holes, the shielding area of ​​the concave plate is reduced, which makes it easier for the fan blades to blow and cool the cooling water, which is beneficial to the heat dissipation of the cooling water.

[0020] Preferably, the cooling channel is spiral.

[0021] By adopting the above technical solution, the cooling water is in full contact with the inner wall of the hopper, thereby improving the cooling effect of the cooling water on the hopper and reducing the possibility of the material melting inside the hopper and clogging the hopper.

[0022] Preferably, a feed port is provided on the top of the injection molding machine body; the feed port is communicated with the interior of the barrel of the injection molding machine body, and the hopper is connected to the feed port via a flange.

[0023] By adopting the above technical solution, the installation and disassembly of the hopper are convenient, and the setting of the flange makes the connection between the hopper and the feed port simple and convenient, which facilitates the disassembly and replacement of the hopper.

[0024] Preferably, a semiconductor refrigeration plate is fixedly connected to the outer side wall of the water tank.

[0025] By adopting the above technical solution, the semiconductor refrigeration plate cools the water tank, thereby further cooling the cooling water, so that the cooling water inside the water tank can better cool the hopper.

[0026] In summary, this application has the following beneficial effects:

[0027] 1. The cooling water falls on the concave plate through the return pipe, and the baffle is used to block the cooling water, which prolongs the time for the cooling water to flow on the concave plate. The motor drives the fan blades to rotate to blow and cool the cooling water on the concave plate. When the cooling water flows through the straight plate along the baffle, the cooling water drives the straight plate, the rotating shaft and the cam to rotate. The cam and the arc surface cooperate to push the pressing plate to slide, so that the pressing plate squeezes the airbag. After the airbag is pressurized, the internal gas is ejected by the air nozzle. The gas ejected by the air nozzle further blows and cools the cooling water, so that the cooling water can be recycled after falling back into the water tank;

[0028] 2. When the first rotating shaft rotates, the second rotating shaft rotates driven by the first belt, and the first bevel gear is meshed with the second bevel gear, so that the second rotating shaft drives the third rotating shaft and the tipping bucket to rotate. During the rotation of the tipping bucket, the cooling water in the water tank is collected and thrown to scatter the cooling water, so that the fan blades have a better cooling effect on the cooling water;

[0029] 3. When the third shaft rotates, the fourth shaft rotates driven by the second belt, thereby driving the stirring plate to rotate, promoting the tumbling motion of the cooling water in the water tank, thereby accelerating the heat dissipation and cooling of the cooling water in the water tank, so that the cooling water can be better recycled.

By setting the cooling channel 21 to a spiral shape, the cooling water is in full contact with the inner wall of the hopper 2, thereby improving the cooling effect of the cooling water on the hopper 2 and reducing the possibility of the material melting inside the hopper 2 and clogging the hopper 2. The cooling water flowing out from the outlet of the cooling channel 21 flows back to the water tank 3 through the reflux pipe 31, and the water tank 3 is cooled by the semiconductor refrigeration plate 37 to achieve cooling of the cooling water.

[0039] like Figure 3 and Figure 4As shown, a motor 34 is installed on the top of the water tank 3; a first rotating shaft 341 is fixedly connected to the output end of the motor 34; a fan blade 35 is fixedly connected to the end of the first rotating shaft 341; a concave plate 33 is fixedly connected to the inner wall of the water tank 3 on the same side as the return pipe 31; a diversion mechanism 5 for diverting cooling water is provided inside the concave plate 33; the outlet of the return pipe 31 is directly opposite to the concave plate 33; the diversion mechanism 5 includes a pair of baffles 51, a pair of rotating shafts 52 and a plurality of straight plates 53; a pair of baffles 51 are fixedly connected to the inner wall of the concave plate 33, and the baffles 51 and the inner wall of the concave plate 33 are inclined; a pair of rotating shafts 52 are rotatably connected to the top of the concave plate 33; a plurality of straight plates 53 are fixedly connected to the outer wall of the rotating shaft 52, and a plurality of through holes 531 are provided on the straight plates 53.

[0040] The starting motor 34 drives the first rotating shaft 341 and the fan blades 35 to rotate. The motor 34 is installed on the top of the water tank 3 through the bracket 32. The cooling water falling on the concave plate 33 and the cooling water inside the water tank 3 are blown and cooled through the fan blades 35. When the cooling water flows to the concave plate 33 through the return pipe 31, the baffles 51 staggered on the concave plate 33 extend the time for the cooling water to flow on the concave plate 33, and extend the contact time between the cooling water and the air, so that the fan blades 35 can fully blow and cool the cooling water. When the cooling water flows along the baffle 51 to the straight plate 53, the cooling water drives the rotating shaft 52 and the straight plate 53 to rotate. When the cooling water flows through the through hole 531, it is diverted, so that the cooling water is easier to dissipate heat.

[0041] like Figure 4 and Figure 5 As shown, the end of the rotating shaft 52 that does not contact the concave plate 33 is fixedly connected with a cam 54; a groove 331 is provided on the inner side wall of the concave plate 33 close to the straight plate 53; a jet assembly 55 for cooling the cooling water is provided inside the groove 331; the cam 54 drives the jet assembly 55 to move; the jet assembly 55 includes a pressing plate 551 and an air nozzle 552; the pressing plate 551 is slidably connected inside the groove 331, and an arc surface 553 cooperating with the cam 54 is provided on the side wall of the pressing plate 551 close to the cam 54, and the side wall of the pressing plate 551 away from the cam 54 is connected to the inner side wall of the groove 331 through a spring 554; the air nozzle 552 is fixedly connected to the inner side wall of the concave plate 33; an air bag 555 is provided inside the groove 331; the air bag 555 is communicated with the inside of the air nozzle 552, and the air bag 555 contacts the side wall of the pressing plate 551 close to the spring 554, and a plurality of heat dissipation holes 332 are provided at the bottom of the concave plate 33.

[0042] The rotation of the rotating shaft 52 drives the cam 54 to rotate. The rotation of the cam 54 pushes the pressure plate 551 to squeeze the airbag 555 through the cooperation with the arc surface 553 on the side wall of the pressure plate 551. The airbag 555 is pressurized to eject air, so that the gas inside the airbag 555 is ejected by the air nozzle 552. The gas ejected by the air nozzle 552 further dissipates the heat of the cooling water on the concave plate 33. The spring 554 is provided to enable the cam 54 and the pressure plate 551 to achieve cyclic extrusion, so that the cooling water can be more fully cooled when flowing on the concave plate 33. The heat dissipation holes 332 are provided to reduce the shielding area of ​​the concave plate 33, so that the fan blades 35 can blow air to cool the cooling water, which is beneficial to the heat dissipation of the cooling water.

[0043] like Figure 3 As shown, a tumbling mechanism 6 for stirring the cooling water is arranged inside the water tank 3; the tumbling mechanism 6 is driven by the first rotating shaft 341, and the tumbling mechanism 6 comprises a second rotating shaft 61, a third rotating shaft 62, a tipping bucket block 63 and a first belt 64; the second rotating shaft 61 is rotatably connected to the outer wall of the water tank 3, and the end of the second rotating shaft 61 close to the first rotating shaft 341 is fixedly connected to a first pulley 611; the middle part of the first rotating shaft 341 is fixedly connected to a second pulley 612; the first belt 64 is sleeved on the first rotating shaft 341. The outside of the pulley 611 and the second pulley 612; the end of the second rotating shaft 61 away from the first pulley 611 is fixedly connected to the first bevel gear 65; the third rotating shaft 62 is rotatably connected to the inner wall of the water tank 3, the end of the third rotating shaft 62 close to the first bevel gear 65 extends out of the water tank 3, and the end of the third rotating shaft 62 extending out of the water tank 3 is fixedly connected to the second bevel gear 66; the first bevel gear 65 is meshed with the second bevel gear 66; the tipping bucket 63 is fixedly connected to the outer wall of the third rotating shaft 62.

[0044] The second rotating shaft 61 is rotatably connected to the outer wall of the water tank 3 through the fixing plate 36. When the motor 34 drives the first rotating shaft 341 and the second pulley 612 to rotate, the first pulley 611 is driven by the first belt 64 to rotate, thereby driving the second rotating shaft 61 and the first bevel gear 65 to rotate, and the first bevel gear 65 is meshed with the second bevel gear 66 to drive the third rotating shaft 62 and the bucket block 63 to rotate. During the rotation of the bucket block 63, the cooling water is collected and thrown, which accelerates the dissipation of the heat of the cooling water, so that the fan can better dissipate the heat and cool down the cooling water. By setting a plurality of bucket blocks 63, the effect of throwing the cooling water is better, which accelerates the cooling of the cooling water.

[0045] like Figure 3As shown, a stirring mechanism 7 for stirring the cooling water is arranged inside the water tank 3; the stirring mechanism 7 is driven by the third rotating shaft 62, and the stirring mechanism 7 comprises a fourth rotating shaft 71, a stirring plate 72 and a second belt 73; the fourth rotating shaft 71 is rotatably connected to the inner wall of the water tank 3, and the end of the fourth rotating shaft 71 close to the second bevel gear 66 extends out of the water tank 3, and the end of the fourth rotating shaft 71 extending out of the water tank 3 is fixedly connected to the third pulley 711; the end of the third rotating shaft 62 extending out of the water tank 3 is fixedly connected to the fourth pulley 712; the second belt 73 is sleeved on the outside of the third pulley 711 and the fourth pulley 712; the stirring plate 72 is fixedly connected to the outer wall of the fourth rotating shaft 71.

[0046] The third shaft 62 drives the fourth pulley 712 to rotate during rotation, and the third pulley 711 is driven to rotate under the action of the second belt 73, thereby causing the fourth shaft 71 to rotate. The fourth shaft 71 drives the stirring plate 72 to rotate during rotation, and the stirring plate 72 is used to stir and tumble the cooling water at the bottom of the water tank 3, thereby promoting the movement of the cooling water and accelerating the dissipation of the heat of the cooling water.

[0047] like Figure 1 As shown, a feed port 11 is provided on the top of the injection molding machine body 1; the feed port 11 is connected to the inside of the barrel of the injection molding machine body 1, and the hopper 2 is connected to the feed port 11 through a flange; the hopper 2 and the feed port 11 are connected by setting a flange, so that the connection between the hopper 2 and the feed port 11 is simple and convenient, and the hopper 2 is easy to disassemble and replace.

[0048] Working principle: The hopper 2 is installed at the feed port 11 on the top of the injection molding machine body 1 and connected through a flange. The raw materials are transported to the inside of the injection molding machine body 1 through the hopper 2. When the hopper 2 is cooled, the water pump 41 is started. The water pump 41 draws the cooling water in the water tank 3 from the water inlet pipe 42. The cooling water is transported to the inside of the cooling channel 21 through the water outlet pipe 43. When the cooling water flows in the cooling channel 21, the heat is taken away by the cooling water in the form of heat conduction, thereby realizing the cooling of the hopper 2. The cooling water flowing out of the cooling channel 21 is returned to the water tank 3 through the return pipe 31 to realize the recycling of the cooling water. When the cooling water flows into the water tank 3 from the end of the return pipe 31, the cooling water falls on the concave plate 33. The concave plate Baffles 51 are staggeredly arranged on the concave plate 33, and the cooling water is blocked by the baffles 51, which prolongs the time for the cooling water to flow on the concave plate 33, thereby prolonging the time for the cooling water to contact with the air. When the cooling water flows on the concave plate 33, the motor 34 drives the first rotating shaft 341 and the fan blades 35 to rotate, and the cooling water on the concave plate 33 is blown and cooled by the rotation of the fan blades 35 to prevent the high temperature of the refluxed cooling water from affecting the cooling work of the hopper 2. When the cooling water flows through the straight plate 53 along the baffles 51, the cooling water drives the straight plate 53 and the rotating shaft 52 to rotate and then slide down. A through hole 531 is opened on the straight plate 53, so that the cooling water is diverted when passing through the through hole 531, and drives the cam 531 during the rotation of the rotating shaft 52. 4 is rotated, and the cam 54 contacts the pressure plate 551 during the rotation process. The cam 54 and the arc surface 553 cooperate to push the pressure plate 551 to slide, so that the pressure plate 551 squeezes the airbag 555. After the airbag 555 is compressed, the internal gas is ejected by the air nozzle 552. The gas ejected by the air nozzle 552 blows and cools the cooling water that slides down, thereby further dissipating the heat of the cooling water. The cooling water on the concave plate 33 falls back into the water tank 3 after heat dissipation, so that the cooling water can be reused; when the motor 34 drives the first rotating shaft 341 to rotate, the second rotating shaft 61 is driven by the first belt 64 to rotate, and the second rotating shaft 61 drives the first bevel gear 65 to rotate, and the first bevel gear 65 and the second bevel gear 66 is meshed, thereby driving the third rotating shaft 62 and the tipping bucket block 63 to rotate. During the rotation of the tipping bucket block 63, the cooling water in the water tank 3 is collected and thrown, thereby promoting the heat dissipation and cooling of the cooling water in the water tank 3. When the third rotating shaft 62 rotates, the fourth rotating shaft 71 rotates under the drive of the second belt 73, thereby driving the stirring plate 72 to rotate, thereby promoting the tumbling motion of the cooling water in the water tank 3, so that the fan blades 35 have a better cooling effect on the cooling water. The heat dissipation holes 332 set on the concave plate 33 are used for the circulation of heat inside the water tank 3, reducing the influence of the concave plate 33 on heat dissipation, and the semiconductor refrigeration plate 37 outside the water tank 3 cools the water tank 3, thereby realizing the cooling of the cooling water in the water tank 3.

[0049] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
