The present utility model will be described in further detail with reference to the accompanying drawings.

As shown in fig. 1-3, an injection molding die 8 apparatus includes a frame 1. One side of the frame 1 is provided with a fixing frame 2. An injection rod 3 is glidingly arranged on the fixing frame 2. The top of the injection rod 3 is hinged with a swing rod 4. The other end of the swing rod 4 is hinged with a fixed rod 5. The fixed rod 5 is fixedly connected with the fixed frame 2. The fixing frame 2 is provided with a hopper 6 corresponding to the injection rod 3. The hopper 6 is provided with a heating device 7 for melting the plastic particles in the hopper 6. The bottom of the hopper 6 is provided with a die 8, and the position of the die 8 corresponding to the bottom of the hopper 6 is provided with an injection hole, so that molten plastic particles are conveniently extruded into the die 8.

Correspondingly, the frame 1 is provided with a feeding device 9 for automatic feeding and a die device 10 for facilitating the separation or approaching extrusion of the die 8 to enable products to be molded and output.

1. Feeding device 9

The feeding device 9 comprises brackets 11 which are arranged on two sides of the top of the hopper 6 and fixedly connected with the hopper 6. The brackets 11 are respectively provided with a storage box 12 in a sliding way. The bottom of the storage box 12 is provided with a discharge hole 13 for outputting plastic particles. When the storage box 12 moves to enable the discharge hole 13 to correspond to the top of the hopper 6, at the moment, plastic particles move out of the hopper 6 along the discharge hole 13, so that the aim of facilitating feeding is fulfilled.

Wherein a connecting rod 14 is hinged to one side of the storage tank 12. The connecting rod 14 is hinged with a driving rod 15. The driving rod 15 is eccentrically connected with a gear 16. Wherein the middle parts of the two gears 16 are meshed with a driving shaft 17. Two gears 16 are located on either side of a drive shaft 17. A connecting plate 18 is connected between the driving shaft 17 and the injection rod 3. When the injection rod 3 moves up, the drive shaft 17 can be driven up, so that the gear 16 which is in mesh with the drive shaft 17 rotates. The gear 16 rotates to drive the driving rod 15 and the connecting rod 14 moves, so that the storage box 12 slides back and forth on the bracket 11, and stops when the injection rod 3 leaves the hopper 6, at this time, the discharging hole 13 of the storage box 12 is placed above the hopper 6, and plastic particles are input into the hopper 6.

When the plastic particles enter the hopper 6 and are gradually melted, the injection rod 3 moves downwards, so that the injection rod 3 drives the driving shaft 17 to move downwards, and the two gears 16 rotate reversely, so that the storage box 12 moves back and forth on the bracket 11, and the plastic particles with smaller quantity enter the hopper 6 when the discharge hole 13 is arranged above the hopper 6.

As the injection rod 3 gradually moves into the hopper 6, the plastic fluid that has been melted in the hopper 6 is pushed into the mold 8, and the plastic fluid in the mold 8 solidifies to form the shape of the product.

Preferably, an output shaft 19 is hinged to the bottom of one side of the swing rod 4, the output shaft 19 is connected with an air cylinder 20, and the swing rod 4 swings through the up-and-down pushing of the air cylinder 20, so that the injection rod 3 hinged to the swing rod 4 is driven to move up and down.

Under the above arrangement, the purpose of automatic feeding is achieved without manually adding corresponding plastic particle raw materials. In addition, under the above arrangement, when the injection rod 3 moves upwards, the gear 16 rotates to enable the storage box 12 to reciprocate back and forth, so that the bottom discharge hole 13 corresponds to the hopper 6, and plastic particles enter the hopper 6, so that the plastic particles are prevented from being blocked due to interaction of the plastic particles caused by too many plastic particles entering at one time. The reciprocating storage tank 12 also adds a small amount of plastic particles to the hopper 6 as the injection rod 3 moves down to reduce the feed pressure as the injection rod 3 moves up.

It should be noted that the heating device 7 is located below the hopper 6, so that the plastic particles located above the hopper 6 are not melted, thereby reducing the problem of adhesion of the plastic particles to the top of the hopper 6 after melting.

2. Die apparatus 10

The die apparatus 10 includes a pushing frame 21 provided on one side of the die 8. Correspondingly, the bottom of the frame 1 is also provided with a chute 22 for sliding the pushing frame 21. A toothed bar 23 is connected to one side of the pushing frame 21. The toothed bar 23 is engaged with a first toothed wheel 24, and the first toothed wheel 24 is engaged with a second toothed wheel 25. The second gear tooth 25 is engaged with a sliding rod 26. The slide bar 26 is fixedly connected with one side of the driving shaft 17.

Wherein the mold 8 includes a fixed mold 27 and a slip mold 28. The fixed die 27 is fixedly arranged with the frame 1, and the sliding die 28 is fixedly connected with the pushing frame 21. When the injection rod 3 moves downwards, the driving shaft 17 can be driven to move downwards, so that the second gear tooth 25 is driven to rotate anticlockwise, the first gear tooth 24 is driven to rotate clockwise, the first gear tooth 24 drives the toothed bar 23 to slide, and the pushing frame 21 is driven to slide. The pushing frame 21 drives the sliding die 28 to slide on the frame 1 to tightly abut against the fixed die 27.

Further, the thickness of the first gear tooth 24 is smaller than that of the second gear tooth 25, and the toothed bar 23 and the sliding bar 26 are staggered.
