Description

Technical Field

[0001] The present invention relates to the technical field of plastic injection molding, and particularly relates to an injection molding device for producing plastic products. Background Art

[0002] In existing plastic product injection molding devices, a barrel is used to store materials. The position of the barrel is relatively high, and thus the materials are conducted downward relying on their own weight. Then, a stirring mechanism is used to stir the materials, so as to promote the materials to flow out of the outlet more efficiently. However, the current stirring device cannot clean the inner wall of the stirring barrel, which affects the mixing and stirring efficiency, reduces the working efficiency, and has poor practicability.

[0003] To solve the above problems, a Chinese patent with the publication number CN221496685U discloses an injection molding device for plastic products, which includes a stirring barrel. Two feeding holes are opened at the top end of the stirring barrel, two discharging holes are opened at the bottom end of the stirring barrel, and an L-shaped plate is fixedly installed on the stirring barrel; a cleaning mechanism is arranged inside the stirring barrel. The cleaning mechanism includes a motor, the motor is fixedly installed on the L-shaped plate, the output end of the motor is fixedly installed with a rotating shaft, the end of the rotating shaft far away from the motor is rotatably connected to the bottom end of the stirring barrel, and a plurality of stirring rods are arranged on the rotating shaft; the device makes the two cleaning plates clean and scrape the inner side wall of the stirring barrel by fitting the two cleaning plates with the inner side wall of the stirring barrel, so that the materials are mixed more uniformly and fully, improving the working efficiency and having high practicability.

[0004] The above device has the following problems during actual use: during the flow of materials through the discharging holes, due to the certain viscosity of the materials, the flow rate of the materials is relatively slow. When the materials flow through the discharging holes, if the flow rate of the materials through the discharging holes cannot be promoted and the fluidity of the materials cannot be improved, the overall discharging speed of the materials will be relatively slow, that is, it affects the discharging effect of the materials, reduces the discharging amount of the materials, and results in poor practicability. Summary of the Invention

[0005] The present invention provides an injection molding device for producing plastic products to solve the problems of relatively slow material discharging speed and poor discharging effect of existing injection molding devices.

[0006] To achieve the above object, the present invention adopts the following technical solution: An injection molding device for plastic product production, comprising a box body with an inlet and an outlet, a feeding pipe, and stirring mechanisms symmetrically arranged on both sides of the box body along the width direction of the box body; the feeding pipe is communicated with the outlet; the stirring mechanism includes a rotating shaft, a plurality of stirring blades equidistantly arranged along the axial direction of the rotating shaft, a material guiding component, and a power component for driving the rotating shaft to rotate; the rotating shaft is rotatably connected to the box body; the stirring blades are fixedly connected to the rotating shaft; the material guiding component includes a slider, a top block, a plurality of material guiding blocks equidistantly arranged along the length direction of the top block, and a driving part for driving the slider to reciprocate along the length direction of the box body; the slider is slidably connected to the feeding pipe; the top block is fixedly connected to the slider; the material guiding blocks are fixedly connected to the top block, and the outer wall of the feeding pipe is located on the movement track of the material guiding blocks.

[0007] The principle and advantages of this solution are:

[0008] 1. Put the material into the box body along the inlet, and drive the rotating shaft to rotate through the power component. Then, under the drive of the rotating shaft, the stirring blades can stir the material in the box body. Therefore, under the stirring action of the stirring blades, the stirring blades can continuously and efficiently promote the material to be fed along the feeding pipe, thus avoiding the accumulation of the stirring blades and enhancing the feeding effect of the material.

[0009] 2. During the feeding of the material through the feeding pipe, the slider reciprocates along the length direction of the box body, and then the material guiding blocks can continuously impact the outer wall of the feeding pipe. After being impacted, the outer wall of the feeding pipe can promote the material to move vertically downward, so that the material can be fed more fully and comprehensively under the vibration effect, further enhancing the feeding effect of the material.

[0010] Furthermore, it further includes a flow part arranged on the slider; the stirring part includes a side block and a plurality of flow blocks equidistantly arranged along the length direction of the side block; the side block is fixedly connected to the slider; the flow blocks are fixedly connected to the side block.

[0011] During the movement of the slider, the slider drives the flow blocks to move synchronously through the side block. During the movement of the flow blocks, the flow blocks can horizontally stir the material in the feeding pipe. On the one hand, it can make the material be stirred more fully and comprehensively, and on the other hand, it can improve the fluidity of the material in the feeding pipe again, making the material flow more completely in the feeding pipe, that is, ensuring that the material can be efficiently fed through the feeding pipe and improving the practicability of the feeding of the feeding pipe.

[0012] Furthermore, it further includes a linkage part symmetrically arranged on both sides inside the feeding pipe along the width direction of the box body; the linkage part includes a linkage shaft, a cylindrical block, a plurality of stirring blocks equidistantly arranged along the circumferential direction of the cylindrical block, and a power unit for driving the linkage shaft to rotate; the linkage shaft is rotatably connected to the feeding pipe; the cylindrical block is connected to the linkage shaft; the stirring blocks are fixedly connected to the cylindrical block.

[0013] After the material is horizontally agitated by the flow block, the agitation block will rotate driven by the cylindrical block. Therefore, during the flow of the material in the downcomer, the material can also be rotationally agitated by the agitation block, making the material more thoroughly agitated for the second time, thereby further improving the uniformity of the agitated material, that is, the material will further increase the feeding speed of the material under the action of the agitation block, ensuring that the material can be efficiently fed in the downcomer.

[0014] Furthermore, the linkage part further includes a linkage unit; the linkage unit includes a first spring and a guiding groove formed on the linkage shaft; the cylindrical block is slidably connected to the guiding groove; both ends of the first spring are respectively connected to the cylindrical block and the linkage shaft; a push block is fixedly connected to the slider; the push block abuts against the cylindrical block.

[0015] During the movement of the slider, the push block moves synchronously. During the movement of the push block, through the mutual cooperation with the first spring, the cylindrical block can reciprocate along the axial direction of the linkage shaft. Through the reciprocating movement of the cylindrical block, the action range of the agitation block is expanded, prompting the agitation block to contact more materials in the downcomer, making the materials more comprehensively and thoroughly agitated under the action of the agitation block, and further improving the feeding efficiency of the materials from the downcomer.

[0016] Furthermore, it further includes feeding parts symmetrically arranged on both sides inside the downcomer along the length direction of the box body; the feeding parts include side blocks, movable blocks, feeding mesh plates, side grooves formed on the side blocks, and a movement unit for driving the movable blocks to reciprocate vertically; the side blocks are fixedly connected to the inner wall of the downcomer; the movable blocks are slidably connected to the side grooves; the feeding mesh plates are fixedly connected to the movable blocks.

[0017] During the multiple agitations of the material by the flow block and the agitation block, the feeding mesh plate can reciprocate along the length direction of the side block. During the movement of the feeding mesh plate, the feeding mesh plate has a certain vertical force, and further the feeding mesh plate can further prompt the material to move vertically downward, enabling the material to be fed from the downcomer more efficiently and thoroughly, thereby enhancing the feeding effect on the material and ensuring the feeding quality of the material.

[0018] Furthermore, the driving part includes a first cam and a second spring; the first cam is fixedly connected to the rotating shaft, and the first cam abuts against the slider; both ends of the second spring are respectively connected to the slider and the outer wall of the downcomer.

[0019] During the rotation of the rotating shaft, the first cam rotates synchronously. During the rotation of the first cam, when the convex part of the first cam abuts against the slider, the slider moves away from the position where the rotating shaft is located, and the second spring is compressed; when the convex part of the first cam no longer abuts against the slider, the slider is reset under the action of the second spring, and the slider moves towards the position closer to the rotating shaft. Therefore, the slider can reciprocate along the length direction of the box body.

[0020] Further, the linkage unit includes a first bevel gear and a second bevel gear; the first bevel gear is fixedly connected to the rotating shaft; the second bevel gear is fixedly connected to the linkage shaft; the first bevel gear meshes with the second bevel gear.

[0021] During the rotation of the rotating shaft, the first bevel gear rotates synchronously. During the rotation of the first bevel gear, since the first bevel gear meshes with the second bevel gear, the second bevel gear drives the linkage shaft to rotate.

[0022] Further, an auxiliary unit is further included; the auxiliary unit includes a drive shaft and an auxiliary member for driving the drive shaft to rotate; the drive shaft is rotatably connected to the blanking pipe; the movement unit includes a second cam and a third spring; the second cam is fixedly connected to the drive shaft, and the second cam abuts against the movable block; both ends of the third spring are respectively connected to the movable block and the side groove.

[0023] The drive shaft is driven to rotate by the auxiliary member. During the rotation of the drive shaft, the second cam rotates synchronously. During the rotation of the second cam, when the convex portion of the second cam abuts against the movable block, the movable block moves vertically downward, and the third spring is compressed; when the convex portion of the second cam no longer abuts against the movable block, the movable block resets under the action of the third spring, and then the movable block moves vertically upward. Therefore, the movable block can perform vertical reciprocating motion.

[0024] Further, the auxiliary member includes a worm and a worm gear; both ends of the worm are respectively fixedly connected to the two linkage shafts; the worm gear is fixedly connected to the drive shaft, and the worm meshes with the worm gear.

[0025] During the rotation of the linkage shaft, the worm rotates synchronously. During the rotation of the worm, since the worm meshes with the worm gear, the worm gear can be driven to rotate by the worm. During the rotation of the worm gear, the drive shaft rotates synchronously. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] Specific implementation process:

[0045] Put the material into the box body 1 along the inlet, start the motor, drive the rotating shaft 3 to rotate through the output shaft of the motor, and then the stirring blade 4 can stir the material in the box body 1 under the drive of the rotating shaft 3. Therefore, under the stirring action of the stirring blade 4, the material in the box body 1 can be fully stirred, and the material can be continuously and efficiently discharged along the blanking pipe 2, thus avoiding the accumulation of the stirring blade 4 and enhancing the material blanking effect.

[0046] During the feeding of the material through the feeding pipe 2, the rotating shaft 3 drives the first cam 20 to rotate. During the rotation of the first cam 20, when the convex part of the first cam 20 abuts against the slider 6, the slider 6 moves away from the position where the rotating shaft 3 is located, and the second spring 21 is compressed; when the convex part of the first cam 20 no longer abuts against the slider 6, the slider 6 resets under the action of the second spring 21, and the slider 6 moves towards the position where the rotating shaft 3 is located. Therefore, the slider 6 can reciprocate along the length direction of the box body 1. By the reciprocating movement of the slider 6 along the length direction of the box body 1, the material guiding block 8 can continuously impact the outer wall of the feeding pipe 2. After being impacted, the outer wall of the feeding pipe 2 can prompt the material to move vertically downward, so that the material can be fed more fully and comprehensively under the vibration effect, further enhancing the feeding effect of the material.

[0047] During the movement of the slider 6, the slider 6 drives the flow block 11 to move synchronously through the side block 10. During the movement of the flow block 11, the flow block 11 can horizontally stir the material in the feeding pipe 2. On the one hand, the material can be stirred more fully and comprehensively, and on the other hand, the fluidity of the material in the feeding pipe 2 is improved again, making the material flow more completely in the feeding pipe 2, that is, ensuring that the material can be efficiently fed through the feeding pipe 2 and improving the practicability of the feeding of the feeding pipe 2.

[0048] After the material is horizontally stirred by the flow block 11, the rotating shaft 3 drives the linkage shaft 12 to rotate through the meshing of the first bevel gear 22 and the second bevel gear 23. During the rotation of the linkage shaft 12, the linkage shaft 12 drives the stirring block 14 to rotate through the cylindrical block 13. Therefore, during the flow of the material in the feeding pipe 2, the material can also be rotationally stirred by the stirring block 14, making the material be stirred more thoroughly for the second time, thereby further improving the uniformity of the stirred material, that is, the material will further increase the feeding speed of the material under the action of the stirring block 14, ensuring that the material can be efficiently fed in the feeding pipe 2.

[0049] During the movement of the slider 6, the push block 16 moves synchronously. During the movement of the push block 16, the push block 16 makes the cylindrical block 13 reciprocate along the axial direction of the linkage shaft 12 through the mutual cooperation with the first spring 15. Through the reciprocating movement of the cylindrical block 13, the action range of the stirring block 14 is expanded, prompting the stirring block 14 to contact more materials in the feeding pipe 2, making the materials be stirred more comprehensively and thoroughly under the action of the stirring block 14, and further improving the feeding efficiency of the materials from the feeding pipe 2.

[0050] During the multiple stirrings of the material by the flow block 11 and the stirring block 14, the worm 27 rotates driven by the linkage shaft 12. During the rotation of the worm 27, through the meshing of the worm 27 and the worm gear 28, the worm gear 28 drives the drive shaft 24 to rotate. During the rotation of the drive shaft 24, the second cam 25 rotates synchronously. During the rotation of the second cam 25, when the convex portion of the second cam 25 abuts against the movable block 18, the movable block 18 moves vertically downward, and the third spring 26 is compressed; when the convex portion of the second cam 25 no longer abuts against the movable block 18, the movable block 18 resets under the action of the third spring 26, and then the movable block 18 moves vertically upward. Therefore, the movable block 18 can perform vertical reciprocating motion.

[0051] During the vertical reciprocating motion of the movable block 18, the movable block 18 drives the blanking screen plate 19 to move synchronously. During the movement of the blanking screen plate 19, the blanking screen plate 19 has a certain acting force in the vertical direction, and thus the blanking screen plate 19 can further promote the material to move vertically downward, enabling the material to be discharged from the blanking pipe 2 more efficiently and thoroughly, thereby enhancing the blanking effect of the material and ensuring the blanking quality of the material.

[0052] In summary, first, the stirring blade 4 pre-treats and stirs the material in the box body 1, thereby improving the fluidity of the material in the box body 1, enabling the material to be discharged more efficiently through the blanking pipe 2. Secondly, during the flow of the material in the blanking pipe 2, the material can vibrate under the action of the guiding block 8, further promoting the discharging of the material. Subsequently, under the combined action of the flow block 11, the stirring block 14, and the blanking screen plate 19, the material can be comprehensively and fully promoted to be discharged through the blanking pipe 2, ensuring the quality of the material injection molding.

Although the present invention has been disclosed above with the preferred embodiment, it is not intended to limit the present invention.
