Technical Field

[0001] The invention relates to the technical field of injection molding equipment, and in particular to a fast cooling injection molding equipment which is convenient for material unloading and demoulding. Background Art

[0002] Injection molding equipment, also known as injection molding machine, is an injection molding equipment that uses plastic molding molds to make thermoplastic plastics or thermosetting plastics into plastic parts. It is mainly composed of components such as a hopper, a barrel, a screw, and a nozzle. It heats and plasticizes the plastic raw materials and injects the molten plastic into the mold cavity at a certain pressure and speed. It usually includes a movable template, a fixed template, a tie rod, a clamping cylinder, etc. The main function is to realize the opening and closing of the mold, and provide sufficient clamping force during the injection and pressure holding process to ensure that the mold is tightly closed. It is composed of an oil pump, an oil motor, an oil cylinder, a hydraulic valve, an oil tank, etc., which provides power for the various moving parts of the injection molding equipment. By controlling the flow direction, pressure and flow of the hydraulic oil, precise control of injection, clamping and other actions is achieved. It is generally composed of a programmable controller, a touch screen, a sensor, a relay, a contactor, etc., which is responsible for controlling and monitoring the entire injection molding process. The operator inputs process parameters and operating instructions through the touch screen, and the PLC controls the actions of each component according to the signal feedback from the sensor.

[0003] When feeding plastic granules for injection molding, in hot weather, the plastic granules enter the injection molding parts and stick to the feed hopper, causing blockage in the feeding process. Summary of the invention

[0007] The injection molding component comprises a spiral shell, the side of the spiral shell is fixedly connected to the inner side of the fixed component, one end of the spiral shell is fixedly connected to a large motor, the inner side of the spiral shell is rotatably connected to a spiral blade, one end of the spiral blade is fixedly connected to the output end of the large motor, the end of the spiral shell away from the large motor is fixedly connected to an injection port, the end of the injection port away from the spiral shell is fixedly connected to the inner side of a fixed plate, the side of the spiral shell is fixedly connected to a heating mechanism, the side of the spiral shell is fixedly connected to a feeding pipe, and the top of the feeding pipe is fixedly connected to a loading mechanism; by placing plastic particles in the loading mechanism, the feeding pipe, the spiral shell is filled with plastic particles. The plastic particles continue to enter the spiral shell. By turning on the large motor, the output end of the large motor drives the spiral blade to rotate inside the spiral shell. The heating work of the heating mechanism melts the material. Under the action of the spiral blade, the material is transported forward and compacted along the screw groove. Under the dual action of external heating and spiral blade shearing, the material is gradually plasticized, melted and homogenized. When the spiral blade rotates, the material is pushed to the head of the spiral blade under the action of the friction and shearing force of the screw groove. At the same time, the spiral blade retreats under the reaction of the material, so that the head of the spiral blade forms a material storage space, completing the plasticization process, and injecting the molten material in the spiral shell into the cavity of the fixed plate through the injection port;

[0008] The feeding mechanism comprises a feeding shell, the bottom of the feeding shell is fixedly connected to the top of the feeding pipe, the inner side of the feeding shell is fixedly connected to an upper bracket, the inner side of the feeding shell is fixedly connected to a lower bracket, the lower bracket is arranged below the upper bracket, the top of the upper bracket is fixedly connected to a small motor, the bottom of the upper bracket is rotatably connected to a stirring rod, the bottom of the stirring rod is rotatably connected to the top of the lower bracket, the output end of the small motor is fixedly connected to the top of the stirring rod, the side of the stirring rod is fixedly connected to a rotating rod, and the side of the rotating rod is fixedly connected to a cleaning component; The particles are placed in the feeding shell, and the small motor is turned on to drive the stirring rod to rotate inside the feeding shell through the output end of the small motor, so as to avoid blockage during the feeding of the plastic particles. At the same time, it can avoid the sticking of the plastic particles in the feeding shell when the weather is hot, thereby causing a large-scale sticking and aggregation of the plastic particles in the feeding shell. At the same time, a cleaning component is arranged on the inner side of the rotating rod. When the rotating rod rotates, the cleaning component can be separated from the inner side of the rotating rod by the action of centrifugal force, so as to clean the inner side of the feeding shell.

[0009] Preferably, the cleaning assembly includes a sliding rod, the inner side of the sliding rod is slidably connected to the inner side of the rotating rod, the sliding rod one end away from the rotating rod is fixedly connected to a connecting plate, the upper and lower sides of the connecting plate are slidably connected to the inner side of the rotating rod, one side of the connecting plate is fixedly connected to a rubber plate, and the side of the connecting plate away from the rubber plate is fixedly connected to a bent plate, the sliding rod is sleeved with a first spring, one end of the first spring is fixedly connected to the inner side of the rotating rod, and the other end of the first spring is fixedly connected to the connecting plate; when the stirring rod drives the rotating rod to rotate through the output end of the small motor, the centrifugal force causes the connecting rod to rotate. The plate drives the rubber plate to move and collide with the inner wall of the feeding shell. By setting the angle of the rubber plate to be greater than that of the bent plate, when the connecting plate is thrown out by the action of centrifugal force, the rubber plate can collide with the inner wall of the feeding shell, thereby avoiding the impact damage caused by the bent plate and the inner wall of the feeding shell when the connecting plate is thrown out. At the same time, when the rotating rod is driven by the stirring rod to rotate, the inner wall of the feeding shell can be contacted and cleaned by the bent plate, thereby avoiding the impurities attached to the plastic particles from sticking to the inner wall of the feeding shell when the plastic particles are fed, thereby causing the plastic particles to stick to the inner wall of the feeding shell.

[0010] Preferably, the cooling component comprises a water tank, a side of the water tank is fixedly connected to the workbench, a water inlet is fixedly connected to the side of the water tank, a water pump is fixedly connected to the inner side of the water tank, a water outlet end of the water pump is fixedly connected to a connecting mechanism, and the other end of the connecting mechanism is fixedly connected to the fixed plate; when the injection molding work is completed, by turning on the water pump, a cooling water pipeline is arranged on the inner side of the fixed plate, and the water in the water tank enters the cooling water pipeline in the fixed plate through the connecting mechanism through the pumping work of the water pump, so that the cooling water circulates and takes away the heat, and the cold water flows in from the water inlet, flows through the pipeline to absorb the heat, and then flows out from the water outlet, so as to keep the water temperature stable to achieve rapid cooling, which can quickly reduce the temperature of the mold and the product, shorten the molding cycle, and improve the production efficiency;

[0011] Preferably, the connecting mechanism includes a connecting pipe, mesh plates are fixedly connected to both sides of the inner wall of the connecting pipe, one end of the connecting pipe is fixedly connected to the water outlet end of the water pump, the other end of the connecting pipe is fixedly connected to the inner side of the fixed plate, the side of the mesh plate is fixedly connected to a guide rod, a second spring is sleeved on the guide rod, one end of the second spring is fixedly connected to the mesh plate, the other end of the second spring is fixedly connected to a moving frame, the inner side of the moving frame is slidably connected to the side of the guide rod, scrapers are fixedly connected to both sides of the moving frame, and the side of the scraper away from the moving frame contacts the inner wall of the connecting pipe; water in the water tank is extracted by the pumping force of the water pump Enter into the connecting pipe, and then enter into the cooling water pipeline in the fixed plate. At the same time, the impact force of the water flow moving in the connecting pipe causes the moving frame to slide on the guide rod by pulling the second spring, so that the moving frame drives the scrapers on both sides to contact and clean the inner wall of the connecting pipe, thereby cleaning the scale attached to the inner wall of the connecting pipe, thereby preventing the water cooling pipe from scaling. The heat insulation layer formed on the inner wall of the water pipe will hinder the heat from being transferred from the fluid in the pipe to the pipe wall, thereby affecting the heat dissipation effect. With the continuous accumulation of residual substances, the inner diameter of the water pipe gradually becomes smaller, and the water flow cross-sectional area is reduced, thereby increasing the water flow speed and increasing the flow resistance;

[0012] The discharging component comprises a discharging port, the inner side of which is fixedly connected to a conveying mechanism, the inner side of which is fixedly connected to a buffer mechanism, and the buffer mechanism is arranged above the conveying mechanism; an ejection mechanism is arranged inside the fixed plate, which is usually composed of an ejector pin, an ejector rod or a push plate. After the injection molding is completed, the ejector pin or the ejector rod moves forward to eject the plastic product from the fixed plate cavity, so that the plastic product falls into the discharging port. When the plastic product falls, the buffer mechanism can be used to perform buffering and guiding work, so that the plastic product falls on the conveying mechanism, and then the plastic product after injection molding is unloaded and conveyed;

[0013] Preferably, the buffer mechanism includes a fixed frame, both sides of the fixed frame are fixedly connected to the inner side of the discharge port, both sides of the inner wall of the fixed frame are rotatably connected with rotating rods, the sides of the rotating rods are fixedly connected with rubber rods, the inner side of the fixed frame away from the rotating rods is rotatably connected with a roller, the bottom of the fixed frame is fixedly connected with a connecting frame, and the bottom of the connecting frame is fixedly connected with a contact assembly; the plastic product falls onto the fixed frame through the discharge port, and a rotating rod is provided on the inner side of the fixed frame, so that the rotating rod drives the rubber rod to contact and rotate with the plastic product, thereby buffering the fallen plastic product, thereby avoiding the plastic product from being crushed. When the plastic product falls, the impact force is too large, so that the surface of the plastic product is bumped and damaged. At the same time, the rubber rod is tilted, and the plastic product in contact with the rubber rod continues to fall through the roller, so that the roller can contact and wipe the side of the plastic product. The roller is made of sponge material to avoid residual release agent, dust or other impurities on the surface of the plastic product. The plastic product passing through the roller falls on the conveying mechanism for subsequent transmission. At the same time, when the top of the conveyor belt on the conveying mechanism contacts the contact component, the contact component can contact and clean the conveyor belt on the conveying mechanism.

[0014] Preferably, the contact assembly includes a contact rod, the top of the contact rod is slidably connected to the inner side of the connecting frame, the bottom of the contact rod is fixedly connected to a scraper, the contact rod is sleeved with a third spring, the top of the third spring is fixedly connected to the bottom of the connecting frame, and the bottom of the third spring is fixedly connected to the top of the scraper; when the conveyor belt on the conveying mechanism contacts and moves with the scraper, the scraper can scrape off the dust and impurities wiped off the roller, thereby avoiding a large amount of dust and impurities remaining on the conveyor belt of the conveying mechanism when the plastic products are conveyed, so that when the plastic products are conveyed, the dust and impurities will remain and adhere to the surface of the plastic products; at the same time, when the extrusion contact force between the scraper and the surface of the conveyor belt on the conveying mechanism is too large, the scraper moves upward on the inner side of the connecting frame through the contact rod, and at the same time, through the buffering work of the third spring, the extrusion contact force between the scraper and the conveyor belt on the conveying mechanism is avoided to be too large, which will cause extrusion damage to the conveyor belt on the conveying mechanism.

[0015] The beneficial effects of the present invention are as follows:

[0016] 1. The present invention arranges a feeding mechanism to place plastic particles in a feeding shell, and turns on a small motor to drive a stirring rod to rotate in the inner side of the feeding shell through the output end of the small motor, thereby avoiding blockage during the feeding of the plastic particles and preventing the plastic particles from sticking in the feeding shell when the weather is hot, thereby causing a large-scale sticking and aggregation of the plastic particles in the feeding shell. At the same time, a cleaning component is arranged on the inner side of the rotating rod, and when the rotating rod rotates, the cleaning component can be separated from the inner side of the rotating rod through the action of centrifugal force, so as to clean the inner side of the feeding shell.

[0017] 2. The present invention provides a cleaning component. When the stirring rod drives the rotating rod to rotate through the output end of the small motor, the centrifugal force causes the connecting plate to drive the rubber plate to move and collide with the inner wall of the feeding shell. By setting the angle of the rubber plate to be greater than the bent plate, when the connecting plate is thrown out through the centrifugal force, the rubber plate can collide with the inner wall of the feeding shell, thereby avoiding the bent plate from causing impact damage to the inner wall of the feeding shell when the connecting plate is thrown out. At the same time, when the rotating rod is driven to rotate by the stirring rod, the bent plate can contact and clean the inner wall of the feeding shell, thereby avoiding the impurities attached to the plastic particles from sticking to the inner wall of the feeding shell when the plastic particles are fed, thereby causing the plastic particles to stick to the inner wall of the feeding shell.

[0018] 3. The present invention sets a connecting mechanism, and the water in the water tank enters the connecting pipe through the extraction force of the water pump, and then enters the cooling water pipeline in the fixed plate. At the same time, through the impact force of the water flow moving in the connecting pipe, the movable frame slides on the guide rod by pulling the second spring, so that the movable frame drives the scrapers on both sides to contact and clean the inner wall of the connecting pipe, thereby cleaning the scale attached to the inner wall of the connecting pipe, thereby preventing the water-cooling pipe from scaling easily. The heat-insulating layer formed on the inner wall of the water pipe will hinder the heat from being transferred from the fluid in the pipe to the pipe wall, thereby affecting the heat dissipation effect. With the continuous accumulation of residual substances, the inner diameter of the water pipe gradually becomes smaller, and the water flow cross-sectional area is reduced, thereby increasing the water flow speed and increasing the flow resistance.

[0019] 4. The present invention provides a buffer mechanism, and the plastic product falls onto the fixed frame through the discharge port. A rotating rod is provided on the inner side of the fixed frame, so that the rotating rod drives the rubber rod to contact and rotate with the plastic product, thereby buffering the fallen plastic product, thereby avoiding excessive impact force when the plastic product falls, thereby causing bumps and damages to the surface of the plastic product. At the same time, the rubber rod is tilted, and the plastic product in contact with the rubber rod continues to fall through the roller, so that the roller can contact and wipe the side of the plastic product. The material of the roller is sponge material, so that mold release agent, dust or other impurities will not remain on the surface of the plastic product. The plastic product passing through the roller falls on the conveying mechanism for subsequent transmission. At the same time, when the top of the conveyor belt on the conveying mechanism contacts the contact component, the contact component can contact and clean the conveyor belt on the conveying mechanism.

The material is melted by the heating work of the heating mechanism 74. Under the action of the spiral blade 75, the material is transported forward and compacted along the screw groove. Under the dual action of external heating and shearing of the spiral blade 75, the material is gradually plasticized, melted and homogenized. When the spiral blade 75 rotates, the material is pushed to the head of the spiral blade 75 under the action of the friction force and shearing force of the screw groove. At the same time, the spiral blade 75 retreats under the reaction of the material, so that the head of the spiral blade 75 forms a material storage space, completing the plasticization process, and injecting the molten material in the spiral shell 71 into the cavity of the fixed plate 5 through the injection port 72;

After the injection molding is completed, the ejector pin or the ejector rod moves forward to eject the plastic product from the cavity of the fixed plate 5, so that the plastic product falls into the discharge port 81. When the plastic product falls, the buffer mechanism 83 can perform buffering and guiding work, so that the plastic product falls on the conveying mechanism 82, and then the plastic product after injection molding is unloaded and conveyed;

[0047] The buffer mechanism 83 includes a fixed frame 831, both sides of which are fixedly connected to the inner side of the discharge port 81, both sides of the inner wall of the fixed frame 831 are rotatably connected with rotating rods 832, the sides of the rotating rods 832 are fixedly connected with rubber rods 833, the inner side of the fixed frame 831 away from the rotating rods 832 is rotatably connected with a roller 834, the bottom of the fixed frame 831 is fixedly connected with a connecting frame 835, and the bottom of the connecting frame 835 is fixedly connected with a contact assembly 836; the plastic product falls onto the fixed frame 831 through the discharge port 81, and the rotating rod 832 is provided on the inner side of the fixed frame 831, so that the rotating rod 832 drives the rubber rod 833 to contact and rotate with the plastic product, thereby buffering the fallen plastic product. In order to avoid excessive impact force when the plastic product falls, thereby causing bumps and damage to the surface of the plastic product, the rubber rod 833 is tilted, and the plastic product in contact with the rubber rod 833 continues to fall through the roller 834, so that the roller 834 can contact and wipe the side of the plastic product. The material of the roller 834 is sponge material, which prevents the surface of the plastic product from residual release agent, dust or other impurities. The plastic product passing through the roller 834 falls on the conveying mechanism 82 for subsequent transmission. At the same time, when the top of the conveyor belt on the conveying mechanism 82 contacts the contact component 836, the contact component 836 can contact and clean the conveyor belt on the conveying mechanism 82.

[0048] The contact assembly 836 includes a contact rod 8361, the top of the contact rod 8361 is slidably connected to the inner side of the connecting frame 835, the bottom of the contact rod 8361 is fixedly connected with a scraper 8362, a third spring 8363 is sleeved on the contact rod 8361, the top of the third spring 8363 is fixedly connected to the bottom of the connecting frame 835, and the bottom of the third spring 8363 is fixedly connected to the top of the scraper 8362; when the conveyor belt on the conveying mechanism 82 moves in contact with the scraper 646, the scraper 646 can scrape off the dust and impurities wiped off by the roller 834, thereby avoiding damage to the plastic. When the plastic products are being transported, a large amount of dust and impurities will remain on the conveyor belt of the conveyor mechanism 82, so that when the plastic products are being transported, the dust and impurities will remain on the surface of the plastic products. At the same time, when the extrusion contact force between the scraper 646 and the surface of the conveyor belt of the conveyor mechanism 82 is too large, the scraper 8362 moves upward inside the connecting frame 835 through the contact rod 8361, and at the same time, the third spring 8363 works as a buffer, thereby avoiding the phenomenon that the extrusion contact force between the scraper 8362 and the conveyor belt of the conveyor mechanism 82 is too large, which will cause extrusion damage to the conveyor belt of the conveyor mechanism 82.

[0049] The specific workflow is as follows:

[0050] The plastic raw material enters the injection molding part 7, is heated and plasticized into a uniform melt, the mold clamping cylinder 2 drives the movable plate 9 to move, so that the movable plate 9 and the fixed plate 5 are closed, and then provides sufficient clamping force to prevent the mold from opening during injection. The injection molding part 7 injects the plasticized plastic melt into the closed mold cavity. In the mold cavity, the plastic melt is pressurized to make up for the volume reduced due to cooling shrinkage, and then the cooling part 6 is turned on for cooling to solidify the plastic melt. After cooling, the mold clamping cylinder 2 opens the mold, ejects the plastic product and drops it on the discharge part 8, and then the plastic product after injection is transported to complete an injection molding cycle;

[0051] By placing the plastic particles in the feeding mechanism 77, the plastic particles in the spiral shell 71 continuously enter the spiral shell 71 through the feeding pipe 76, and by turning on the large motor 73, the spiral blade 75 is driven to rotate inside the spiral shell 71 through the output end of the large motor 73, and the material is melted by the heating work of the heating mechanism 74. Under the action of the spiral blade 75, the material is transported forward and compacted along the screw groove, and is gradually plasticized, melted and homogenized under the dual action of external heating and shearing of the spiral blade 75. When the spiral blade 75 rotates, the material is pushed to the head of the spiral blade 75 under the action of the friction force and shearing force of the screw groove. At the same time, the spiral blade 75 retreats under the reaction of the material, so that the head of the spiral blade 75 forms a material storage space, and the plasticization process is completed, and the molten material in the spiral shell 71 is injected into the cavity of the fixed plate 5 through the injection port 72;

[0052] The plastic particles are placed in the feeding shell 771, and the small motor 773 is turned on. The stirring rod 775 is driven to rotate inside the feeding shell 771 through the output end of the small motor 773 to avoid blockage during the feeding of the plastic particles. At the same time, it can prevent the plastic particles from sticking in the feeding shell 771 when the weather is hot, thereby causing a large-scale sticking and aggregation of the plastic particles in the feeding shell 771. At the same time, a cleaning component 777 is provided on the inner side of the rotating rod 776. When the rotating rod 776 rotates, the cleaning component 777 can be separated from the inner side of the rotating rod 776 by the action of centrifugal force, so that the inner side of the feeding shell 771 is cleaned;

[0053] When the stirring rod 775 drives the rotating rod 776 to rotate through the output end of the small motor 773, the centrifugal force causes the connecting plate 7772 to drive the rubber plate 7773 to move and collide with the inner wall of the upper material shell 771. By setting the angle of the rubber plate 7773 to be greater than the bent plate 7774, when the connecting plate 7772 is thrown out by the centrifugal force, the rubber plate 7773 can collide with the inner wall of the feeding shell 771, thereby avoiding the bent plate 7774 from causing collision damage to the inner wall of the feeding shell 771 when the connecting plate 7772 is thrown out. At the same time, when the rotating rod 776 is driven to rotate by the stirring rod 775, the bent plate 7774 can contact and clean the inner wall of the feeding shell 771, thereby avoiding the impurities attached to the plastic particles from sticking to the inner wall of the feeding shell 771 when the plastic particles are being fed, thereby causing the plastic particles to stick to the inner wall of the feeding shell 771.

[0054] When the injection molding work is finished, the water pump 62 is turned on, and a cooling water pipeline is set on the inner side of the fixed plate 5. The water in the water tank 61 is pumped by the water pump 62, and enters the cooling water pipeline in the fixed plate 5 through the connecting mechanism 64, so that the cooling water circulates and takes away the heat. The cold water flows in from the water inlet 63, flows through the pipeline to absorb the heat, and then flows out from the water outlet. The water temperature is kept stable to achieve rapid cooling, which can quickly reduce the temperature of the mold and the product, shorten the molding cycle, and improve production efficiency.

[0055] The water in the water tank 61 enters the connecting pipe 641 through the extraction force of the water pump 62, and then enters the cooling water pipeline in the fixed plate 5. At the same time, the impact force of the water flow moving in the connecting pipe 641 causes the moving frame 645 to slide on the guide rod 643 by pulling the second spring 644, so that the moving frame 645 drives the scrapers 646 on both sides to contact and clean the inner wall of the connecting pipe 641, thereby cleaning the scale attached to the inner wall of the connecting pipe 641, thereby preventing the water cooling pipe from being easily scaled. The heat insulation layer formed on the inner wall of the water pipe will hinder the heat from being transferred from the fluid in the pipe to the pipe wall, thereby affecting the heat dissipation effect. With the continuous accumulation of residual substances, the inner diameter of the water pipe gradually becomes smaller, and the water flow cross-sectional area is reduced, thereby increasing the water flow speed and increasing the flow resistance.

[0056] The fixed plate 5 is provided with an ejection mechanism inside, which is usually composed of an ejector pin, an ejector rod or a push plate. After the injection molding is completed, the ejector pin or the ejector rod moves forward to eject the plastic product from the cavity of the fixed plate 5, so that the plastic product falls into the discharge port 81. When the plastic product falls, the buffer mechanism 83 can perform buffering and guiding work, so that the plastic product falls on the conveying mechanism 82, and then the plastic product after injection molding is unloaded and conveyed;

[0057] The plastic product falls onto the fixed frame 831 through the discharge port 81. A rotating rod 832 is provided on the inner side of the fixed frame 831, so that the rotating rod 832 drives the rubber rod 833 to contact and rotate with the plastic product, thereby buffering the fallen plastic product, thereby preventing the plastic product from being hit too hard when it falls, thereby preventing the surface of the plastic product from being damaged by bumps. At the same time, the rubber rod 833 is tilted, so that the plastic product in contact with the rubber rod 833 continues to fall through the roller 834, so that the roller 834 can contact and wipe the side of the plastic product. The material of the roller 834 is sponge material, so that the mold release agent, dust or other impurities will not remain on the surface of the plastic product. The plastic product passing through the roller 834 falls onto the conveying mechanism 82 for subsequent transmission. At the same time, when the top of the conveyor belt on the conveying mechanism 82 contacts the contact component 836, the contact component 836 can contact and clean the conveyor belt on the conveying mechanism 82.

[0058] When the conveyor belt on the conveying mechanism 82 moves in contact with the scraper 646, the scraper 646 can scrape off the dust and impurities wiped off by the roller 834, thereby avoiding a large amount of dust and impurities remaining on the conveyor belt of the conveying mechanism 82 when the plastic products are conveyed, so that when the plastic products are conveyed, the dust and impurities will remain and adhere to the surface of the plastic products. At the same time, when the extrusion contact force between the scraper 646 and the surface of the conveyor belt on the conveying mechanism 82 is too large, the scraper 8362 moves upward on the inner side of the connecting frame 835 through the contact rod 8361, and at the same time, the third spring 8363 works as a buffer, thereby avoiding the phenomenon that the extrusion contact force between the scraper 8362 and the conveyor belt on the conveying mechanism 82 is too large, which will cause extrusion damage to the conveyor belt on the conveying mechanism 82.
