Description

Technical Field

[0001] This application relates to the field of injection molding machine equipment technology, and in particular to an injection molding machine hopper transfer assembly. Background Technology

[0002] Injection molding machines, also known as injection molding machines or injection molding machines, are the main molding equipment used to produce various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They are classified as vertical, horizontal, and all-electric. Injection molding machines heat the plastic, apply high pressure to the molten plastic, and inject it to fill the mold cavity.

[0003] A related injection molding machine hopper adapter cylinder has its upper end connected to the feed cylinder and its lower end fixedly connected to the screw heating cylinder. The hopper adapter cylinder is set at an inclination. In use, the material is fed from the feed cylinder, and the material falls into the screw heating cylinder under the action of the hopper adapter cylinder and gravity.

[0004] When material falls into the screw heating cylinder, it will adhere to the screw heating cylinder and the periphery of the hopper transfer cylinder. Over time, this will cause blockage of the hopper transfer cylinder, thus affecting the performance. Utility Model Content

Detailed Implementation

[0048] The following is in conjunction with the appendix Figure 1-5 This application will be described in further detail. Example 1

[0049] Combination Figure 1 and Figure 2 This application discloses a hopper transfer assembly for an injection molding machine, comprising: a hopper transfer cylinder 11, a feed hopper 12, an anti-blocking cylinder 13, and a sealing component. One end of the hopper transfer cylinder 11 is fixedly disposed on the screw heating cylinder, and the axis of the hopper transfer cylinder 11 forms an angle with the axis of the screw heating cylinder. The feed hopper 12 is located above the hopper transfer cylinder 11, and the feed hopper 12 is fixedly connected to the end of the hopper transfer cylinder 11 away from the screw heating cylinder. The lower end of the anti-blocking cylinder 13 is fixedly disposed on the periphery of the feed hopper 12. The sealing component is detachably disposed on the upper end of the anti-blocking cylinder 13. The anti-blocking cylinder 13 is provided with a clearing cavity 15, which communicates with the hopper transfer cylinder 11, and the upper end of the clearing cavity 15 is provided with a mating port 14. The sealing component includes a dust cover 21 and a bolt 22. The dust cover 21 is placed on the mating port 14 and is slidably connected to the anti-blocking cylinder 13. The bolt 22 is threadedly connected to one end of the dust cover 21 and passes through the dust cover 21 to be threadedly connected to the anti-blocking cylinder 13.

[0050] In this embodiment, the hopper transfer cylinder 11 is used to transport the material in the feed hopper 12 to the screw heating cylinder. The hopper transfer cylinder 11 is cylindrical. It should be noted that both the upper and lower connection points of the hopper transfer cylinder 11 are horizontal to ensure a more stable connection. The hopper transfer cylinder 11 is inclined, with the inclination angle set according to specific usage. The feed hopper 12 has a feed inlet 37 at its upper end and a connection port at its lower end. The specifications of the connection port are consistent with those of the upper end of the hopper transfer cylinder 11, ensuring that the material in the feed hopper 12 can enter the hopper transfer cylinder 11. The hopper transfer cylinder 11 and the feed hopper 12 can be fixedly connected by welding. The anti-blocking cylinder 13 is cylindrical and can be integrally formed with the hopper transfer cylinder 11. The hopper transfer cylinder 11 is perpendicular to the ground and communicates with the anti-blocking cylinder 13. The dust cover 21 is circular in shape, and its size is larger than the unblocking cavity 15 of the anti-clogging cylinder 13, enough to close the unblocking cavity 15. The length of the bolt 22 is sufficient to rotatably connect the dust cover 21 and the anti-clogging cylinder 13, allowing the dust cover 21 to rotate along the axial direction of the bolt 22.

[0051] In practical use, the material is fed into the feed hopper 12. Due to the inclined setting of the hopper transfer cylinder 11, the material can enter the screw heating cylinder through the hopper transfer cylinder 11. After a long period of use, the connection between the hopper transfer cylinder 11 and the anti-blocking cylinder 13 will become blocked. Then, the bolt 22 is rotated so that the bolt 22 and the anti-blocking cylinder 13 can move relative to each other, and then the dust cover 21 is rotated so that the dust cover 21 opens the unblocking cavity 15, thereby facilitating manual unblocking of the blockage. Example 2

[0052] Combination Figure 3 and Figure 5 The sealing component includes a dust cover 21 and a fixing post 23. The dust cover 21 is placed on the upper end of the anti-blocking cylinder 13 to close the mating opening 14. The lower end of the fixing post 23 is fixedly installed on the upper end of the dust cover 21, and the upper end of the fixing post 23 is a free end. A sealing ring 24 is provided at the lower end of the dust cover 21, and the sealing ring 24 is embedded in the mating opening 14. The upper end of the sealing ring 24 is fixedly installed on the lower end of the dust cover 21. A post cap 25 is fixedly installed at the free end of the fixing post 23. A mating groove 26 is provided around the periphery of the post cap 25.

[0053] In this embodiment, the dust cover 21 is disc-shaped, and the fixing post 23 is cylindrical. The fixing post 23 and the dust cover 21 can be integrally formed, or they can be fixedly connected by welding or bolting. This embodiment does not impose specific limitations. The height of the fixing post 23 is sufficient for the worker's hand to grip. The sealing ring 24 is made of elastic material. It should be noted that the diameter of the sealing ring 24 is smaller than the diameter of the dust cover 21, and it just abuts against the inner wall of the unblocking cavity 15. The post cap 25 is cylindrical and can be made of rigid material or rubber material. The post cap 25 and the fixing post 23 can be integrally formed. The mating groove 26 is arranged along the axial direction of the post cap 25 to prevent the worker from picking up the dust cover 21.

[0054] In practical use, when the hopper transfer cylinder 11 is blocked, the operator firmly grips the mating groove 26 on the side of the column cap 25 to increase the stability of the grip, and then pulls the column cap 25, causing the column cap 25 to pull the dust cover 21 away from the unblocking cavity 15, thereby unblocking the hopper transfer cylinder 11. When it is not necessary to unblock the hopper transfer cylinder 11, the operator holds the column cap 25 and then fastens the dust cover 21 onto the unblocking cavity 15, while the sealing ring 24 abuts against the inner circumference of the unblocking cavity 15, thereby initially fixing the dust cover 21 and the anti-blocking cylinder 13. Example 3

[0055] Combination Figure 5 The upper end of the anti-clogging cylinder 13 is detachably equipped with a unblocking component 3, which includes an installation cylinder 31, a filter screen 32, a motor 33, and a fan 34. The lower end of the installation cylinder 31 is threaded to the upper end of the anti-clogging cylinder 13, and an installation cavity is vertically arranged inside the installation cylinder 31. The filter screen 32 is fixedly installed in the installation cavity, dividing the installation cavity into a collection cavity 35 and a power cavity 36. The motor 33 is fixedly installed at the end of the power cavity 36 away from the anti-clogging cylinder 13. The fan 34 is located at the end of the power cavity 36 away from the anti-clogging cylinder 13, and the fan 34 is fixedly connected to the output shaft of the motor 33. The collection cavity 35 is provided with a feed inlet 37 at the end near the anti-clogging cylinder 13. A handle 16 is fixedly installed at the end of the installation cylinder 31 away from the anti-clogging cylinder 13.

[0056] In this embodiment, the mounting cylinder 31 is cylindrical, with a diameter smaller than that of the anti-clogging cylinder 13. The outer circumference of the mounting cylinder 31 has external threads, and the inner circumference of the unblocking cavity 15 has internal threads. The size of the collecting cavity 35 is larger than that of the power cavity 36, meaning the collecting cavity 35 is sufficient to allow the fan 34 to rotate. The filter screen 32 is circular and fixedly mounted on the inner circumference of the unblocking cavity 15. The handle 16 facilitates the handling of the mounting cylinder 31. In practical use, when the hopper transfer cylinder 11 is clogged, the mounting cylinder 31 is threadedly connected to the anti-clogging cylinder 13, fixing them relatively. The motor 33 is then started, causing the fan 34 to rotate, creating negative pressure within the unblocking cavity 15, which in turn generates suction, drawing the blockage from the hopper transfer cylinder 11 into the collecting cavity. This method is simple and easy to operate.

[0057] This specific embodiment is merely an explanation of this application and is not intended to limit it. After reading this specification, those skilled in the art can make modifications to this embodiment without contributing any inventive step, but such modifications are protected by patent law as long as they fall within the scope of the claims of this application.
