Description

Technical Field

[0001] This utility model relates to the field of plastic injection molding, specifically to an injection molding equipment for processing plastic baskets. Background Technology

[0002] Injection molding machines are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. They can heat the plastic, apply high pressure to the molten plastic, and make it eject and fill the mold cavity. After cooling and solidification, plastic products with a shape almost identical to the mold cavity are obtained.

[0003] During the injection molding process of plastic crates using an injection molding machine, air bubbles may be generated. This is generally caused by air mixed in with the raw material, or by excessive air being mixed in during the feeding process due to the material particles being too small or uneven in size; or by poor venting of the equipment itself, which prevents the plastic from expelling gas smoothly during the filling process, thus forming air bubbles. Therefore, there is still room for improvement in venting. Utility Model Content

[0028] Please see Figures 1 to 4 This utility model provides a technical solution: an injection molding equipment for processing plastic baskets, including a main push rod 1, a feeding structure 2 and a discharging structure 3. The feeding structure 2 is fixedly connected to the front end of the main push rod 1, and the discharging structure 3 is fixedly connected to the front end of the feeding structure 2.

[0029] The defoaming structure 11 is fixed at the front end of the main discharge pipe 10, and defoaming and discharge are achieved by vibrating the main discharge pipe 10.

[0030] One end of the auxiliary discharge pipe 9 is fixed to the front end of the feeding structure 2, and the other end of the auxiliary discharge pipe 9 is connected to the main discharge pipe 10, which plays the role of assisting the feeding structure 2 in discharging material.

[0031] In use, the main discharge pipe 10 can convey the molten plastic in the feeding structure 2. For plastic particles that are not completely melted in one go, the auxiliary discharge pipe 9 is responsible for conveying the plastic that is melted twice. The plastic particles entering the main discharge pipe 10 are defoamed under the vibration of the defoaming structure 11 and finally discharged outward.

[0032] Example 2

[0033] Based on Embodiment 1, the discharge structure 3 includes an auxiliary discharge pipe 9, a main discharge pipe 10, and a defoaming structure 11. The auxiliary discharge pipe 9 is provided in two sets. One end of the two sets of auxiliary discharge pipes 9 is fixedly connected to the feeding structure 2, and the other end of the auxiliary discharge pipe 9 is fixedly connected to the main discharge pipe 10. The front end of the main discharge pipe 10 is fixedly connected to the defoaming structure 11.

The top end of the two-section discharge pipe 13 has an opening, and the extrusion tube 17 is fixedly connected inside the opening. The front end of the two-section discharge pipe 13 is fixedly connected to the second screw 16.

[0036] In use, the molten plastic particles in the feeding structure 2 are collected and flowed into the second discharge pipe 13 through the first discharge pipe 12. The vibration motor 14 drives the two sets of connecting rods 15 to vibrate. The connecting rods 15 vibrate the molten plastic particles in the second discharge pipe 13, causing the air bubbles inside the plastic to be discharged upwards to complete the defoaming.

[0043] In use, plastic granules are poured into the feed hopper 8. The heating chamber 7 has a conveying pipe that is connected to the first screw 6. The screw of the first screw 6 stirs the plastic granules in the conveying pipe. As the temperature inside the heating chamber 7 rises, the plastic granules begin to melt and are discharged outward through the auxiliary discharge pipe 9 and the main discharge pipe 10. A filter screen is installed at the opening of the auxiliary discharge pipe 9. Plastic granules that do not pass through the filter screen of the auxiliary discharge pipe 9 will be melted again in the heating chamber 7 and then flow into the main discharge pipe 10 through the auxiliary discharge pipe 9.
