Technical Field

[0001] The utility model relates to the technical field of residual material recovery of injection molding machines, in particular to a residual material recovery structure of injection molding machines. Background Art

[0002] An injection molding machine is a molding device that uses a plastic molding mold to make plastic products of various shapes from thermoplastics or thermosetting plastics. It can heat the plastic, apply high pressure to the molten plastic, cause it to eject and fill the mold cavity, and then cool it to form.

[0003] Injection molding machines are usually provided with a raw material barrel, in which materials are stored. After use, molten materials tend to remain on the inner wall of the raw material barrel. In order to avoid the residue solidifying and affecting the normal use and waste of the raw material barrel, the residual materials usually need to be recycled. Traditional methods mostly require manual flushing of the inner wall of the raw material barrel with a water pipe, but such cleaning method is less effective and time-consuming and labor-intensive. Therefore, the utility model proposes an injection molding residual material recycling structure for an injection molding machine. Utility Model Content

DETAILED DESCRIPTION

[0021] In order to make the above-mentioned purposes, features and advantages of the utility model more obvious and easy to understand, the specific implementation of the utility model is described in detail below in conjunction with the accompanying drawings. In the following description, many specific details are set forth to facilitate a full understanding of the utility model. However, the utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without violating the connotation of the utility model, so the utility model is not limited by the specific implementation disclosed below.

[0022] Reference Figure 1-5 The invention discloses an injection molding residual material recovery structure of an injection molding machine, comprising a storage barrel 1. A cleaning mechanism for cleaning the inner wall of the storage barrel 1 is arranged inside the storage barrel 1. The cleaning mechanism comprises a moving ring 12 which is slidably connected to the storage barrel 1. A scraper 11 is fixedly sleeved on the outer wall of the moving ring 12. It should be noted that the scraper 11 is made of rubber, and the outer wall of the scraper 11 is in contact with the inner wall of the storage barrel 1.

[0023] In the utility model, a limiting mechanism for limiting the position of the cleaning mechanism is provided in the material storage barrel 1, and the limiting mechanism includes a limiting rod 7 fixedly connected between the bottom and the inner top of the material storage barrel 1, and two symmetrically arranged sliders 10 are fixedly connected to the inner wall of the movable ring 12. The limiting rod 7 passes through one of the sliders 10 and is slidably connected thereto. Under the action of the limiting rod 7, the slider 10 is limited, and then the cleaning mechanism is limited, thereby improving the stability of the cleaning mechanism during movement.

[0024] In the utility model, a moving mechanism for moving the cleaning mechanism is provided inside the material storage barrel 1, and the moving mechanism includes a reciprocating screw 8 rotatably connected between the bottom and the top of the material storage barrel 1, the reciprocating screw 8 passes through another slider 10 and cooperates with it, and a motor 15 is fixedly connected to the upper end of the material storage barrel 1, and the end of the output shaft of the motor 15 is fixedly connected to the upper end of the reciprocating screw 8, and a cam 18 is fixedly sleeved on the output shaft of the motor 15. The motor 15 can be used to simultaneously drive the cleaning mechanism to move and the pumping mechanism to pump liquid, so as to reasonably use the driving source and improve the practicality of the device.

[0025] In the utility model, an annular tube 6 is fixedly sleeved on the outer wall of the storage barrel 1, and a plurality of nozzles 13 connected with the annular tube 6 are arranged on the inner wall of the storage barrel 1. A pumping mechanism for pumping liquid to the annular tube 6 is arranged at the upper end of the storage barrel 1. The pumping mechanism includes a fixed tube 4 fixedly connected to the upper end of the storage barrel 1, a piston 19 is slidably connected in the fixed tube 4, the fixed tube 4 is connected to the annular tube 6 through a one-way liquid outlet pipe 3, and a one-way liquid inlet pipe 2 is fixedly connected to the upper end of the fixed tube 4. The plurality of nozzles 13 are distributed at equal intervals in the circumferential direction. When storing materials in the storage barrel 1, it should be noted that the storage liquid level must be lower than the nozzles 13.

[0026] In the utility model, a sliding rod 16 is fixedly connected to the side wall of the piston 19, and a moving plate 17 that cooperates with the cam 18 is fixedly connected to the end of the sliding rod 16. The side wall of the piston 19 is elastically connected to the inner wall of the fixed tube 4 through a spring 14. The spring 14 can quickly reset the piston 19 after the cam 18 squeezes the piston 19 to move, so that the piston 19 can achieve the effect of reciprocating movement.

[0027] When the utility model is used, the output shaft of the driving motor 15 rotates, driving the reciprocating screw 8 to rotate, driving the sliding block 10 matched therewith to move back and forth, thereby driving the moving ring 12 and the scraper 11 to move back and forth, and the scraper 11 repeatedly wipes the inner wall of the storage barrel 1 to clean the inner wall of the storage barrel 1 to avoid material residue and affect the normal use of the storage barrel 1. During the rotation of the output shaft of the motor 15, the cam 18 is driven to rotate. Under the action of the cam 18 and the spring 14, the piston 19 moves back and forth. At this time, the water inlet pipe can be connected with the one-way liquid inlet pipe 2. When the piston 19 moves to the right, the water in the water pipe is drawn into the fixed pipe 4. When the piston 19 moves to the left, the water is pumped into the annular pipe 6, and then sprayed out by the nozzle 13, so as to flush the inner wall of the storage barrel 1 and improve the cleaning effect.

Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
