Of course, the clamping grooves 67 may be provided with multiple groups at intervals along the height direction of the discharging channel 61, and the corresponding clamping buckles 68 are also provided with multiple groups at intervals along the height direction of the collecting box 66, so long as each clamping buckle 68 can correspond to each clamping groove 67 and can fix the position of the collecting box 66 on the discharging channel 61. When the burrs in the collecting box 66 are more, the buckle 68 can be directly operated to be pulled out from the clamping groove 67, the collecting box 66 can be taken down from the blanking channel 61, then the burrs in the collecting box 66 can be poured out, and the cleaning is more convenient.

Referring to fig. 4, the auxiliary discharging assembly 63 includes an auxiliary plate 631 slidably connected in the discharging channel 61 and a linear motor 632 for driving the auxiliary plate 631 to move vertically, the linear motor 632 may be mounted on an outer wall of the discharging channel 61 and located at a side close to the clipper 62, the linear motor 632 is located at an upper side of the clipper 62, a mounting block 633 is fixedly connected to a slider of the linear motor 632, the auxiliary plate 631 is mounted on the mounting block 633, and a sliding groove 611 for sliding the mounting block 633 is provided through both inner and outer sides of the discharging channel 61. The auxiliary plate 631 mounted on the mounting block 633 is vertically moved by the linear motor 632 to thereby provide a downward force to the workpiece positioned in the discharging path 61.

Wherein, in order to avoid that the workpiece is abutted on the auxiliary plate 631 and cannot drop down when the workpiece reaches the blanking channel 61, the auxiliary plate 631 is hinged with the mounting block 633, a torsion spring is mounted on a hinge shaft of the auxiliary plate 631, a fixed block 634 is fixedly connected on the mounting block 633, the fixed block 634 is positioned on the upper side of the auxiliary plate 631, one end of the torsion spring is abutted on one side of the auxiliary plate 631 away from the fixed block 634, and the other end of the torsion spring is abutted on the mounting block 633. Normally, the auxiliary plate 631 is pushed to abut against the fixed block 634 under the action of the elasticity of the torsion spring, at this time, the auxiliary plate 631 is in a horizontal state, and when the auxiliary plate 631 abuts against the workpiece to drive the workpiece to move downwards, the auxiliary plate 631 can normally apply force to the workpiece due to the arrangement of the fixed block 634, so that the workpiece is ensured to normally descend, and burrs on the workpiece are trimmed by the trimming knife 62. When a new workpiece falls on the auxiliary plate 631, the auxiliary plate 631 is driven to rotate around the hinge shaft of the auxiliary plate 631 and the mounting block 633 under the action of the gravity of the workpiece, so that the workpiece can smoothly slide from one side of the auxiliary plate 631 away from the linear motor 632 to the lower side of the auxiliary plate 631, and is pushed by the auxiliary plate 631 to move downwards, thereby ensuring smooth trimming of burrs on the workpiece.

In order to ensure that the workpiece is always located at one side of the auxiliary plate 631 away from the linear motor 632, the blanking channel 61 may be disposed to be inclined integrally, and the blanking channel 61 is gradually inclined from top to bottom toward the direction of the linear motor 632, so that the workpiece reaching the blanking channel 61 is always clung to one side of the blanking channel 61 away from the chute 611 under the action of gravity, so that the workpiece can smoothly slide from between the side wall of the blanking channel 61 and the auxiliary plate 631 to the lower side of the auxiliary plate 631.

Referring to fig. 1, four legs 12 are provided at the lower side of the table 1, and the conveying device 7 includes a conveying table 71 at the lower side of the table 1, a driving roller (not shown) rotatably connected to the conveying table 71, a driven roller (not shown) rotatably connected to the conveying table 71, a conveying belt 72 sleeved on the driving roller and the driven roller, and a conveying motor 73 fixedly connected to the conveying table 71 for driving the driving roller to rotate, and an output shaft of the conveying motor 73 is connected to the driving roller. Under the drive of the conveying motor 73, the conveying belt 72 moves from one side of the blanking channel 61 away from the linear motor 632 to one side of the blanking channel 61 close to the linear motor 632, when a workpiece in the blanking channel 61 arrives on the conveying belt 72, the conveying belt 72 drives the workpiece to move towards the blanking channel 61 close to the linear motor 632, and the moving direction of the workpiece is consistent with the tilting direction of the blanking channel 61, so that the workpiece can smoothly arrive on the conveying belt 72 from the blanking channel 61.

The implementation principle of the high-efficiency injection molding machine for the injection mold provided by the embodiment of the application is as follows: in use, the feeder 2 will deliver the melted material to the mold clamping space through the injection port 311 and cool the melted material in the mold clamping space to form a workpiece. After the workpiece is shaped, the operator directly operates the driving assembly 33 to drive the movable mold 32 to slide away from the fixed mold 31, and the first ejector pin 43 does not move along with the movable mold 32 due to the arrangement of the abutting assembly 52, and at this time, the limiting plate 51 also slides in the limiting groove 321, and the end of the first ejector pin 43 extends out of the end of the driven mold 32 to push the workpiece driven mold 32 upwards and downwards. Along with the continuous sliding of the movable mold 32, when the limiting plate 51 and the limiting groove 321 are abutted against one side of the fixed mold 31, the movable mold 32 drives the first ejector pin 43 to move towards the direction of the driving assembly 33 together, and at the moment, the first ejector pin 43 drives the second ejector pin 44 to move through the mounting rod 42, so that the end part of the second ejector pin 44 extends out of the side wall of the fixed mold 31, and a workpiece is pushed down from the fixed mold 31, so that the demolding of the workpiece is realized. The work pieces will fall into the discharging passage 61 by gravity and the work pieces will slide along the passage from the upper side of the auxiliary plate 631 to the lower side of the auxiliary plate 631 by gravity driving the auxiliary plate 631 to rotate about the hinge shaft of the auxiliary plate 631 and the mounting block 633 and pressing the torsion springs so that a passage for the work pieces to pass through is formed between the inner walls of the auxiliary plate 631 and the discharging passage 61. When the workpiece slides to the burr on the workpiece, the auxiliary plate 631 is driven by the linear motor 632 to move downwards and push the workpiece to move downwards, so that the burr on the workpiece can be smoothly trimmed by the trimming blade 62. The workpiece trimmed of burrs falls down from the blanking passage 61 onto the conveyor 72, and is conveyed by the conveyor 72 to the next process.

The above embodiments are not intended to limit the scope of the present application, so: all equivalent changes in structure, shape and principle of the application should be covered in the scope of protection of the application.
