Detailed Implementation

[0020] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0021] Example:

[0022] A horizontal injection molding machine for plastic parts, such as Figures 1-5 As shown, the machine includes a machine tool 1, an extrusion cylinder 2, a hopper 3, a screw press rod 4, a fixed box 5, a motor 6, a heating ring 10, a forming box 11, a mold plate 12, a solenoid valve 13, a first electric push rod 14, a cooling plate 15, and a feeding mechanism. The extrusion cylinder 2 is horizontally fixed to the upper part of the machine tool 1. The hopper 3 is connected and communicates with the upper left side of the extrusion cylinder 2. The screw press rod 4 is rotatably connected inside the extrusion cylinder 2. The fixed box 5 is fixed to the left side of the extrusion cylinder 2. The motor 6 is fixed inside the fixed box 5 by bolts. The output shaft of the motor 6 is connected to the screw press rod 4. Multiple heating rings 10 are provided on the outer wall. A forming box 11 is fixedly connected to the right side of the machine tool 1. Mold plates 12 are symmetrically slidably connected inside the forming box 11. The two mold plates 12 are attached to each other, and the internal slot of the mold plate 12 is connected to the right port of the extrusion cylinder 2 after being attached. A solenoid valve 13 is provided at the right port of the extrusion cylinder 2. First electric push rods 14 are installed on both the front and rear sides inside the forming box 11. The output shafts of the first electric push rods 14 are connected to the adjacent mold plates 12. A cooling plate 15 is installed on one side of each mold plate 12. A feeding mechanism is provided on the right side of the machine tool 1.

[0023] like Figure 1 , Figure 3 , Figure 4 and Figure 5As shown, the blanking mechanism includes a discharge plate 16, a second electric push rod 17, a push block 18, a fixed rod 19, a protective door 20, and a latch 22. The discharge plate 16 is located directly below the two mold plates 12. The second electric push rod 17 is fixed to the upper part of the forming box 11 by bolts. The push block 18 is connected to the output end of the second electric push rod 17. The opening on the right side of the machine tool 1 is aligned with the discharge plate 16. The fixed rod 19 is welded to the right side of the machine tool 1. The protective door 20 is located directly in front of the opening. The latch 22 is inserted between the protective door 20 and the right side of the machine tool 1.

[0024] As shown in Figure 1 and Figure 2 , it also includes a stirring rod 7 and a track 8. The stirring rod 7 is connected to the middle of the hopper 3 by rotating. The track 8 is connected between the left side of the stirring rod 7 and the output shaft of the motor 6.

[0025] As shown in Figure 1 and Figure 3 , it also includes a handle 21 and a foot pad 101. The handle 21 is welded to the right side of the protective door 20. The machine tool 1 is provided with a plurality of foot pads 101.

[0026] As shown in Figure 1 and Figure 2 , it also includes a controller 9. The controller 9 is installed on the front side of the machine tool 1. The controller 9 is electrically connected to the motor 6, the heating ring 10, the electromagnetic valve 13, the first electric push rod 14, the cooling plate 15, and the second electric push rod 17.

[0027] When the plastic material needs to be processed into various shaped products, this device can be used. First, the staff needs to start the motor 6 and the heating ring 10 in sequence through the controller 9. After the motor 6 is started, it will drive the spiral press rod 4 and the stirring rod 7 to rotate. Then, the plastic particle material is poured into the hopper 3. Under the action of the stirring rod 7, the granular plastic is not easy to block when passing through the hopper 3 and entering the extrusion cylinder 2, improving the operation efficiency. Next, the spiral press rod 4 will crush the plastic material and move to the right side, while the heating ring 10 will continuously heat the plastic material in the extrusion cylinder 2 until it is in a molten state, and then it will come into the forming box 11. The molten plastic material is injected into the mold plate 12 under the high pressure of the spiral press rod 4. When the mold plate 12 is completely filled, the electromagnetic valve 13 will close the outlet of the extrusion cylinder 2 to prevent excess plastic material from entering the mold plate 12. At the same time, the staff needs to start the cooling plate 15 to cool and shape the plastic material in the mold plate 12, ensuring that the plastic material in the mold plate 12 is completely solidified to form the required shape.

[0028] After the shaping is finished, the staff needs to start the first electric push rod 14 at the same time, the first electric push rod 14 will drive the two mold plates 12 to move away from each other, so that the mold plates 12 are opened, and the finished product will fall into the opening below because the mold plates 12 are away from each other, but sometimes the finished product may be attached to the mold plates 12, at this time, the staff needs to start the second electric push rod 17, the second electric push rod 17 drives the push block 18 to move downward, and the finished product on the mold plate 12 is pushed out downward, so that it falls into the opening below, finally, the staff needs to pull out the pin 22, and rotate the protective door 20 to open, then take out the finished product, thus a round of plastic material processing is completed, and the above steps can be repeated to continuously process the plastic material.

[0029] Although the present disclosure has been described with reference to a limited number of embodiments, it will be appreciated by those skilled in the art that various other embodiments can be devised without departing from the scope of the present application. Accordingly, the scope of the present application should be limited only by the appended claims.
