[0014] 1. This utility model, by activating the cooler, can transmit cold air to the injection molded shell, thereby cooling down the molded plastic toy and preventing people from being burned when taking the molded plastic toy out.

[0015] 2. When the cylinder's telescopic rod moves forward, it can drive the fixed rod and the double wedge block to move forward. The forward movement of the double wedge block will squeeze the push plate to move forward. The forward movement of the push plate can push the plastic toy that has fallen onto the baffle forward, thus replacing manual pushing of the plastic toy, saving time and effort.

Detailed Implementation

[0022] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0023] A plastic injection molding machine for toy processing, see reference. Figures 1-5 As shown, the system includes a base 1, a drive motor 2, a conveyor frame 21, a feeding frame 3, a screw feeder 4, a heater 5, a fixing frame 6, an injection molding shell 7, a cooler 8, a baffle 9, a rubber pad 91, a discharge plate 10, and a cylinder 11. The drive motor 2 is mounted on the top left side of the base 1, and the conveyor frame 21 is connected to the right side of the drive motor 2. The conveyor frame 21 is made of transparent material for easy observation of the feeding process. The feeding frame 3 is connected to the top left side of the conveyor frame 21 and is funnel-shaped. The output shaft of the drive motor 2 is connected to the screw feeder 4 via a coupling on its right side. The screw feeder 4 is located inside the conveyor frame 21, and its rotation transports the plastic raw material to the right. A heater 5 is mounted on the top of the base 1, and the conveying pipe of the heater 5 is connected to... The conveyor frame 21 is connected, the heater 5 can heat and mold the plastic raw material, the base 1 has a fixed frame 6 welded to the top right side, the fixed frame 6 is connected to the injection shell 7 at the front, the base 1 has a cooler 8 installed on the top right side, the cooler 8 can cool the molded plastic toy, the base 1 has a baffle 9 connected to the top right side, the baffle 9 has a rubber pad 91 connected to the bottom inside, the rubber pad 91 plays a buffering and protective role to prevent the molded plastic toy from being damaged, the baffle 9 has a feeding plate 10 connected to the front side, the feeding plate 10 is set at an angle, the feeding plate 10 has a cylinder 11 installed on the upper part, the telescopic rod of the cylinder 11 is connected to the injection shell 7 at the rear side, the conveyor pipe of the cooler 8 is connected to the injection shell 7 at the rear side, and the right side of the conveyor frame 21 is connected to two injection shells 7.

[0024] When the device is needed, it is first placed in the designated location. Then, the plastic material to be injected is poured into the conveyor frame 21 through the feed frame 3. Next, the heater 5 and drive motor 2 are activated. The heater 5 dissipates heat, allowing hot air to enter the injection shell 7 through the conveyor frame 21. Simultaneously, the output shaft of the drive motor 2 rotates, driving the screw feeder 4 to rotate. The rotation of the screw feeder 4 transports the plastic material to the right, allowing it to be transported into the two injection shells 7. Then, the drive motor 2 is turned off. The plastic material inside the injection shell 7 is heated and molded by the hot air emitted by the heater 5. After the material is injection molded, the cooler 8 is activated, which transmits cold air to the injection shell 7 to cool the molded plastic toy. After cooling is complete, the cooler 8 is turned off, and the cylinder 11 is activated to control the extension rod of the cylinder 11 to move forward. The extension rod of the cylinder 11 moves forward, causing the front injection shell 7 to move forward, so that the molded plastic toy falls onto the baffle 9. Then, the molded plastic toy is pushed forward, so that it falls forward through the unloading plate 10 and is taken away. Finally, the extension rod of the cylinder 11 is controlled to move backward to reset and is turned off. Example 2

[0025] Based on Example 1, see [link to Example 1] Figures 4-5 As shown, it also includes a fixed rod 12, a double wedge block 13, a push plate 14 and a spring 15. The fixed rod 12 is welded to the rear of the telescopic rod of the cylinder 11. The double wedge block 13 is connected to the left side of the fixed rod 12. The push plate 14 is slidably provided at the rear of the baffle 9. The push plate 14 can push the molded plastic toy forward when it moves forward. The spring 15 is connected between the front side of the push plate 14 and the baffle 9.

[0026] When the telescopic rod of cylinder 11 moves forward, it drives the fixed rod 12 to move forward. The forward movement of the fixed rod 12 drives the double wedge block 13 to move forward. When the double wedge block 13 moves forward and contacts the push plate 14, the double wedge block 13 will squeeze the push plate 14 to move forward. The spring 15 is compressed, and the forward movement of the push plate 14 can push the plastic toy that has fallen on the baffle 9 forward, so that the plastic toy falls down through the feed plate 10, thereby replacing the manual pushing of the plastic toy, saving time and effort. When the telescopic rod of cylinder 11 moves backward to reset, it can drive the fixed rod 12 and the double wedge block 13 to move backward to reset. The double wedge block 13 separates from the push plate 14, the spring 15 returns to its original state, and the push plate 14 can then move backward to reset.

Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the scope of the claims.
