Abstract
Description
Technical Field
[0001] This invention relates to the field of injection molding technology, and in particular to an injection molding machine for producing slippers. Background Technology
[0002] The production of plastic slippers generally adopts injection molding technology, in which plastic granules are melted and plasticized and injected into the mold cavity. After cooling and solidification, they can be mass-produced. The technology is mature and has high production efficiency, and it is currently the mainstream processing method for the industrial production of plastic slippers.
[0003] In existing injection molding machines used for slipper production, during operation, the molten raw material is difficult to smoothly pass through the check valve of the injection screw to the left end of the injection chamber. This can easily lead to voids and air bubbles due to untimely material replenishment, resulting in incomplete injection, surface holes, and other defects. The material discharge area of the hopper is also prone to the problem of raw material particles accumulating and sticking together, forming bridging and arching, which can easily cause poor material discharge, interruption of material supply, and frequent bridging and clumping. This not only affects the continuous production of the equipment, but also indirectly causes uneven melt replenishment due to unstable material supply, further leading to molding defects such as voids and holes during injection.

[0013] The injection molding machine for slipper production provided by this invention has the following advantages: 1. By cooperating with the pressurizing components in the injection molding mechanism and the pressurizing adjustment mechanism, pressurization is achieved on the right side of the fluid check valve during injection molding. This allows the molten material at the right end of the fluid check valve to smoothly enter the inner left side of the injection chamber, reducing the occurrence of voids or air bubbles in the molten material on the left side of the injection chamber due to untimely replenishment, which could lead to incomplete injection or injection holes.
[0014] 2. Through the coordination of the adjustment components in the injection molding mechanism and the pressure adjustment mechanism, a multi-directional airflow is formed at the lower inner end of the material storage mechanism. This airflow continuously impacts the lower inner area of the material storage mechanism that is prone to bridging. The airflow disperses the accumulated raw materials from the side, disturbs the gaps between particles, breaks the tendency of adhesion and bridging, and the multi-directional airflow mixes with each other to form a surrounding wind field, avoiding the accumulation of raw materials by static compaction, thus eliminating the phenomenon of bridging and clumping from the source.
[0015] 3. Through the coordination of the adjustment components in the pressure adjustment mechanism and the injection molding mechanism, the airflow entering the lower end of the storage mechanism is continuously changed. The continuously changing airflow can not only sweep the feeding channel from multiple angles without dead angles and break the static accumulation state of the material, but also the airflow strength and direction are constantly switching, which can repeatedly disturb the particle arrangement and destroy the material adhesion stress points to avoid the formation of fixed arch structure. At the same time, in conjunction with the vibration transmitted to the lower end of the storage mechanism, it can further prevent negative pressure compaction and agglomeration, and effectively eliminate the phenomenon of material bridging and blockage.
[0016] 4. By sealing and pressurizing the inside of the injection chamber when the injection screw retracts, and bridging the raw material inside the material storage mechanism during injection, the unmelted raw material is evenly introduced into the injection chamber for melting. The molten raw material then smoothly passes through the fluid check valve. The combination of these two methods can further prevent the formation of holes and voids during injection molding, thereby improving the yield of slipper injection molding.

[0020] The specific embodiments of the present invention will be further described in detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of the invention.
[0021] like Figures 1-8 As shown, this embodiment proposes an injection molding machine for slipper production, including a base 5. A mold 4 is fixedly connected to the upper left side of the base 5, and an injection molding mechanism 1 is fixedly connected to the upper right side of the base 5. A pressure adjustment mechanism 2 is fixedly connected to the middle of the injection molding mechanism 1, and a material storage mechanism 3 is fixedly connected to the upper end of the pressure adjustment mechanism 2.

The pressure adjustment mechanism 2 includes a housing 21, a pressure assembly is fixedly connected to the lower inner end of the housing 21, and an adjustment assembly is fixedly connected to the upper inner part of the housing 21.
[0022] In this embodiment, the injection molding mechanism 1 includes an injection chamber 11 and a protective frame 13. An injection screw 12 is rotatably connected inside the injection chamber 11. A fluid check valve 114 is fixedly connected to the left end of the injection screw 12. An oil tank 14 is fixedly connected to the right side of the protective frame 13. A spline shaft 15 is rotatably connected to the inner left side of the oil tank 14. A piston shaft 16 is rotatably connected to the right end of the spline shaft 15.

[0023] In this embodiment, the lower end of the storage cylinder 31 is fixedly connected to the upper end of the housing 21, and the lower end of the housing 21 is fixedly connected to the upper right side of the base 5.
[0024] In this embodiment, the lower end of the injection molding chamber 11 is fixedly connected to the upper middle part of the base 5, the lower end of the protective frame 13 is fixedly connected to the upper right side of the base 5, and the lower end of the reduction motor 112 is fixedly connected to the upper end of the motor bracket on the right side of the base 5.
[0025] In this embodiment, the outer periphery of the fluid check valve 114 is slidably connected to the inner left side of the injection chamber 11, the outer periphery of the piston disc 17 is slidably connected to the inner right side of the oil chamber 14, and the left end of the spline shaft 15 is fixedly connected to the right end of the injection screw 12.
[0026] Specifically, when producing slippers, firstly, the raw material is added into the storage cylinder 31. The raw material enters the injection chamber 11 through the discharge valve 32 and the sealing valve core 33. At the same time, the geared motor 112 and the heating coil 113 are started. The geared motor 112 drives the drive pulley 111 to rotate, which in turn drives the spline shaft 15 to rotate through the transmission belt 110 and the driven pulley 19. This, in turn, drives the injection screw 12 to rotate, conveying the raw material to the left and heating and melting it. The oil pump 18 is started, injecting the hydraulic oil in the base 5 into the inner right side of the oil tank 14. The piston disc 17 pushes the piston shaft 16 to move to the left, which in turn pushes the injection screw 12 to move to the left inside the injection chamber 11 through the spline shaft 15. In conjunction with the fluid check valve 114 at the left end of the injection screw 12, the molten raw material is injected into the mold 4 for plastic molding. After the injection is completed, the oil pump 18 is started to reset the injection screw 12, the mold 4 is opened, the slippers are removed, and the next injection is performed.
[0027] In this embodiment, the pressurizing assembly includes a pressurizing chamber 22. A sealing flap 23 is slidably connected inside the pressurizing chamber 22. A connecting shaft 24 is fixedly connected to the right end of the sealing flap 23. An adjusting gear 218 is meshed with the connecting shaft 24. A rotating rod is rotatably connected to the middle of the adjusting gear 218. The front and rear ends of the rotating rod are fixedly connected to the upper ends of the front and rear sides of the inner housing 21. The adjusting gear 218 meshes with the injection screw 12. A drive seat 25 is fixedly connected to the right end of the injection screw 12. An exhaust check valve 217 is fixedly connected to the left end opening of the pressurizing chamber 22. The upper end of the exhaust check valve 217 is fixedly connected to the lower right end opening of the injection chamber 11. An intake check valve 216 is fixedly connected to the left ends of the front and rear sides of the pressurizing chamber 22. The upper ends of the intake check valve 216 are fixedly connected to the lower ends of the front and rear sides of the discharge valve 32.
[0028] In this embodiment, the lower end of the pressurization chamber 22 is fixedly connected to the inner bottom of the housing 21, and the outer periphery of the connecting shaft 24 is slidably connected to the right end opening of the pressurization chamber 22.
[0029] Specifically, when the injection screw 12 moves to the right, it drives the adjusting gear 218 to move to the left, which in turn drives the sealing flap 23 to move to the left via the connecting shaft 24. This allows the gas inside the pressurized chamber 22 to be injected into the inner right side of the injection chamber 11 through the outlet check valve 217. Simultaneously, when the injection screw 12 initially drives the drive seat 25 to move, it drives the adjusting seat 211 to move to the right. The front adjusting seat 211 cooperates with the one-way transmission gear fixedly connected to the front end of the sealing valve core 33 to drive the sealing valve core 33 to rotate, closing the passage of the discharge valve 32, thereby allowing the inner side of the injection chamber 11 to be closed. The injection chamber is in a closed state. After the gas is continuously injected into the injection chamber 11, it pressurizes the right side of the fluid check valve 114 in the injection chamber 11. Through the cooperation of the pressurizing components in the injection mechanism 1 and the pressurizing adjustment mechanism 2, the right side of the fluid check valve 114 is pressurized during injection. This allows the molten material at the right end of the fluid check valve 114 to smoothly enter the inner left side of the injection chamber 11, reducing the occurrence of voids or air bubbles in the molten material on the left side of the injection chamber 11 due to untimely replenishment, which could lead to incomplete injection or injection holes.
[0030] In this embodiment, the adjustment assembly includes two suction chambers 26, two adjustment seats 211, and six one-way transmission gears. The lower end of the front suction chamber 26 is fixedly connected to the lower front opening of the discharge valve 32, and the lower end of the rear suction chamber 26 is fixedly connected to the upper rear opening of the discharge valve 32. Dustproof mesh plates 27 are fixedly connected to the upper ends of the suction chambers 26. A column 210 is fixedly connected to the middle of the end of the suction chamber 26 near the discharge valve 32. Both ends of the column 210 are provided with wind baffles 28. Rotating plates 29 are rotatably connected to both sides of the wind baffles 28. The adjustment seats 211 are all engaged with the one-way transmission gears. The upper ends of the suction chambers 26 are fixedly connected to the upper left end of the housing 21. The middle of the upper and lower one-way transmission gears is fixedly connected to the end of the wind baffles 28 near the adjustment seats 211. The middle of the middle one-way transmission gears is fixedly connected to the front and rear ends of the sealing valve core 33.
[0031] In this embodiment, the upper ends of the suction chamber 26 are all fixedly connected to the front and rear openings of the upper end of the housing 21, the upper and lower ends of the baffle plate 28 are rotatably connected to the upper and lower ends inside the suction chamber 26, the left end of the adjusting seat 211 is slidably connected to the upper opening on the left side of the housing 21, the right end of the adjusting seat 211 is fixedly connected to the upper left side of the drive seat 25, the middle of the four one-way transmission gears is fixedly connected to the lower end of the baffle plate 28, and the two one-way transmission gears are fixedly connected to the front and rear ends of the sealing valve core 33.
[0032] In this embodiment, the one-way transmission gear component includes a full gear 212, and ratchet 213 is rotatably connected inside the full gear 212. Pads 214 are evenly distributed in the middle of the full gear 212. A spring 215 is fixedly connected to the side of the pawl 214 away from the ratchet 213. The pawl 214 meshes with the ratchet 213. The end of the spring 215 away from the pawl 214 is fixedly connected to the inside of the full gear 212.
[0033] Specifically, when the injection screw 12 initially moves to the left, the drive seat 25 drives the rear one-way transmission gear to rotate the discharge valve 32, opening the discharge valve 32 channel. Material enters the injection chamber 11 from the storage cylinder 31. Simultaneously, the sealing flap 23 resets, drawing air into the lower end of the discharge valve 32 through the air inlet check valve 216, generating a downward suction force. This creates downward airflow from the gap between the materials at the lower end of the storage cylinder 31. At the same time, the front and rear suction chambers 26 can take in air, with the front suction chamber 26 generating an upward airflow. The airflow from the rear side and the air suction chamber 26 at the rear side generate airflow obliquely downward and forward. The airflow from these three different directions can loosen the raw material at the lower end of the storage cylinder 31, preventing bridging of the raw material at the lower end of the storage cylinder 31. Through the cooperation of the adjustment components in the injection molding mechanism 1 and the pressure adjustment mechanism 2, a multi-directional airflow is formed at the lower inner end of the storage mechanism 3. This airflow continuously impacts the easily arched area in the lower inner part of the storage mechanism 3. The airflow disperses the accumulated raw material from the side, disturbs the gaps between particles, and breaks the tendency of adhesion and arching. The multi-directional airflow... The mixing creates a surrounding airflow, preventing the raw materials from settling and compacting, thus eliminating bridging and clumping at the source. As the adjusting seat 211 moves to the right, it simultaneously drives the baffle 28 inside the suction chamber 26 to rotate via the unidirectional transmission gears on the front and rear sides. The rotation of the baffle 28 not only continuously changes the direction of the airflow but also continuously changes the air intake volume of the front and rear suction chambers 26. Furthermore, the rotating plate 29 impacts the central column 210, generating vibration. This vibration is transmitted through the suction chamber 26 to the lower end of the storage mechanism 3, further preventing bridging. In this situation, through the cooperation of the adjustment components in the pressure adjustment mechanism 2 and the injection molding mechanism 1, the airflow entering the lower end of the storage mechanism 3 is continuously changed. The continuously changing airflow can not only sweep the feeding channel from multiple angles without dead angles and break the static accumulation state of the material, but also the airflow strength and direction are constantly switching, which can repeatedly disturb the particle arrangement and destroy the material adhesion stress points to avoid the formation of a fixed arch structure. At the same time, in conjunction with the vibration transmitted to the lower end of the storage mechanism 3, it can further prevent negative pressure compaction and agglomeration, and effectively eliminate the phenomenon of material bridging and blockage in the long term.
[0034] Working principle: When producing slippers, firstly, the raw material is added into the storage cylinder 31. The raw material enters the injection chamber 11 through the discharge valve 32 and the sealing valve core 33. At the same time, the geared motor 112 and the heating coil 113 are started. The geared motor 112 drives the drive pulley 111 to rotate, which in turn drives the spline shaft 15 to rotate through the transmission belt 110 and the driven pulley 19. This, in turn, drives the injection screw 12 to rotate, conveying the raw material to the left and heating and melting it. The oil pump 18 is started, injecting the hydraulic oil in the base 5 into the inner right side of the oil tank 14. The piston disc 17 pushes the piston shaft 16 to move to the left, which in turn pushes the injection screw 12 to move to the left inside the injection chamber 11 through the spline shaft 15. This works in conjunction with the fluid check valve 114 at the left end of the injection screw 12. The molten raw material is injected into the mold 4 for plastic molding. After injection molding is completed, the oil pump 18 is started to reset the injection screw 12, the mold 4 is opened, the slipper is removed, and the next injection is performed. When the injection screw 12 moves to the right, it drives the adjusting gear 218 to move to the left, which in turn drives the sealing flap 23 to move to the left through the connecting shaft 24. The gas inside the pressurization chamber 22 is injected into the inner right side of the injection chamber 11 through the exhaust check valve 217. At the same time, when the injection screw 12 initially drives the drive seat 25 to move, it drives the adjusting seat 211 to move to the right. The front adjusting seat 211 cooperates with the one-way transmission gear fixedly connected to the front end of the sealing valve core 33 to drive the sealing valve core 33 to rotate, closing the passage of the discharge valve 32, thereby making the inside of the injection chamber 11... In a closed state, the continuous injection of gas into the injection chamber 11 pressurizes the right side of the fluid check valve 114 within the injection chamber 11. Through the cooperation of the pressurizing components in the injection mechanism 1 and the pressurizing adjustment mechanism 2, pressurization is achieved on the right side of the fluid check valve 114 during injection. This allows the molten material at the right end of the fluid check valve 114 to smoothly enter the inner left side of the injection chamber 11, reducing the occurrence of voids or air bubbles in the molten material on the left side of the injection chamber 11 due to insufficient replenishment, thus preventing incomplete injection or injection holes. When the injection screw 12 initially moves to the left, the drive seat 25 drives the rear one-way transmission gear to rotate the discharge valve 32, opening the discharge valve 32 channel and allowing material to flow from the storage area. As the material cylinder 31 enters the injection chamber 11, the sealing flap 23 resets, drawing air through the inlet check valve 216 to the lower end of the outlet valve 32, generating a downward suction force. This creates a downward blowing force from the gap between the materials at the lower end of the material storage cylinder 31. Simultaneously, air can enter through the front and rear suction chambers 26. The front suction chamber 26 generates an upward and backward blowing force, while the rear suction chamber 26 generates a downward and forward blowing force. This blowing force from three different directions loosens the material at the lower end of the material storage cylinder 31, preventing bridging. Through the coordination of the adjustment components in the injection molding mechanism 1 and the pressure adjustment mechanism 2, a multi-directional airflow is formed in the lower inner part of the material storage mechanism 3, continuously impacting the easily arched area in the lower inner part of the material storage mechanism 3.The airflow laterally disperses the accumulated raw materials, disturbing the gaps between particles and breaking the tendency of adhesion and arching. The multi-directional airflow mixes to form a surrounding wind field, preventing the raw materials from being statically compacted and agglomerated, thus eliminating bridging and clumping at the source. As the adjusting seat 211 moves to the right, it simultaneously drives the baffle 28 inside the suction chamber 26 to rotate through the one-way transmission gears on the front and rear sides. When the baffle 28 rotates, it not only continuously changes the direction of the airflow but also continuously changes the air intake of the front and rear suction chambers 26. Moreover, the rotating plate 29 will hit the central column 210 to generate vibration, which is transmitted through the suction chamber 26 to At the lower end of the material storage mechanism 3, to further prevent bridging, the adjustment components in the pressure adjustment mechanism 2, in conjunction with the injection molding mechanism 1, achieve continuous airflow variation entering the lower end of the material storage mechanism 3. This continuously changing airflow not only thoroughly flushes the material feeding channel from multiple angles, breaking the static accumulation of materials, but also, through constant switching in airflow strength and direction, repeatedly disturbs the particle arrangement and disrupts the material's adhesion points, preventing the formation of fixed arch structures. Simultaneously, the vibration transmitted to the lower end of the material storage mechanism 3 further prevents negative pressure compaction and agglomeration, effectively eliminating material bridging and blockage in the long term.
