Technical Field

[0001] This utility model relates to the technical field of plastic products, specifically a plastic product cutting gate device. Background Technology

[0002] Plastic products are a general term for daily and industrial products made primarily from plastics. They include all products manufactured using processes such as injection molding and thermoforming. Plastics are a type of synthetic polymer material with plasticity. After plastic products are injection molded, there will be a gate on the surface that needs to be cut off. This requires a gate cutting device, which is used to cut off the gate on the surface of the plastic product.

[0003] Existing gate-cutting equipment for plastic products addresses the issue of gates on the surface of injection-molded plastic products. Current methods primarily employ hydraulic pressure to cut the gates, but this approach fails to properly fix the plastic product during the cutting process. This leads to movement and cutting deviations, resulting in burrs. Therefore, a new gate-cutting equipment for plastic products is needed. Utility Model Content

[0004] The purpose of this invention is to provide a plastic product gate cutting device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a plastic product cutting gate device, comprising a support frame, a discharge trough on the upper surface of the support frame, a base plate fixedly installed on the upper surface of the support frame, a placement plate movably connected above the base plate, a limit groove on the upper surface of the placement plate, a sliding rod on one side of the base plate, a top plate fixedly installed at the upper end of the sliding rod, a hydraulic cylinder on the top plate, a piston rod movably connected inside the hydraulic cylinder, a movable plate fixedly installed at the lower end of the piston rod, a connecting plate movably connected below the movable plate, a second bolt penetrating one side of the connecting plate, a cutting head below the connecting plate, a telescopic rod below the connecting plate, a spring on the outside of the telescopic rod, and a pressure block fixedly installed below the telescopic rod.

[0023] Please see Figure 1-5This utility model provides a technical solution: a plastic product cutting and gate equipment, including a support frame 1, a discharge groove 5 on the upper surface of the support frame 1, a base plate 6 fixedly installed on the upper surface of the support frame 1, a placement plate 7 movably connected above the base plate 6, a first bolt 8 penetrating one side of the placement plate 7, the first bolts 8 being evenly spaced on the placement plate 7, the placement plate 7 can be effectively disassembled and replaced to suit the shape of different plastic products through the setting of the first bolts 8, a limit groove 9 is opened on the upper surface of the placement plate 7, a slide rod 10 is provided on one side of the base plate 6, a top plate 11 is fixedly installed on the upper end of the slide rod 10, a hydraulic cylinder 12 is provided above the top plate 11, a piston rod 13 is movably connected inside the hydraulic cylinder 12, a movable plate 14 is fixedly installed on the lower end of the piston rod 13, and a movable plate 14 is movably connected below the movable plate 14. The connecting plate 15 slides on the outside of the slide rod 10 via the movable plate 14. The slide rod 10 is evenly spaced on the connecting plate 15. The slide rod 10 enhances the stability of the connecting plate 15 during lifting and pressing, and improves the accuracy during cutting. A second bolt 16 passes through one side of the connecting plate 15. A cutting head 17 is provided below the connecting plate 15. A telescopic rod 18 is provided below the connecting plate 15. A spring 19 is provided on the outside of the telescopic rod 18. A pressure block 20 is fixedly installed below the telescopic rod 18. The pressure block 20 forms a telescopic structure with the connecting plate 15 through the telescopic rod 18. The telescopic rod 18 is symmetrically arranged around the central axis of the pressure block 20. When the pressure block 20 is pressed down, the spring 19 on the outside acts as a buffer during the downward extension and retraction of the telescopic rod 18, preventing excessive downward pressure from damaging the surface of the plastic product.

[0024] Please see Figure 1 and Figure 2 The inner surface of the support frame 1 is provided with a sliding groove 2. The sliding groove 2 is movably connected to a slider 3. A collection box 4 is fixedly installed above the slider 3. The material falls into the discharge trough 5 through the cut-out pouring port on the placement plate 7, and then falls from the discharge trough 5 into the collection box 4 inside the support frame 1 for unified collection. This not only facilitates collection by the staff, but also ensures the cleanliness and hygiene of the workbench. The collection box 4 forms a sliding structure with the support frame 1 through the slider 3. The slider 3 is symmetrically arranged about the central axis of the collection box 4. The arrangement of the slider 3 makes it easy for the staff to pull out the collection box 4 and empty the waste material inside the collection box 4.

[0025] Please see Figure 1 , Figure 4 and Figure 5 A rubber pad 21 is attached to the bottom of the pressure block 20. The size of the rubber pad 21 matches the size of the pressure block 20. The rubber pad 21 plays a certain role in buffering the pressure block 20 during the pressing process, and also protects the plastic products from being crushed.

[0026] Working principle: When using this plastic product cutting gate equipment, first connect the external power supply, then place the freshly injection-molded plastic product into the limiting groove 9 in the placement plate 7, then turn on the hydraulic cylinder 12 switch to drive the power source of the hydraulic pump. The hydraulic pump presses hydraulic oil into the hydraulic cylinder 12, thereby pushing the internal piston rod 13. The piston rod 13 pushes the movable plate 14 and the connecting plate 15 down. First, the pressure block 20 and the rubber pad 21 contact the top of the plastic product. The pressure block 20 compacts the plastic product for fixed positioning. Then, the telescopic rod 18 above the pressure block 20 and the spring 19 extend and compress, pushing the connecting plate down. The cutting head 17 on one side continues to descend and cut the plastic product at the front gate. After cutting, the hydraulic cylinder 12 switch is turned off. The cut-off gate waste falls into the discharge trough 5 and then into the collection box 4 in the support frame 1 for unified collection. The above steps continue to cut the gate of the next plastic product. Finally, when the device is no longer in use, the external power is cut off, and the collection box 4 in the support frame 1 is pulled out by the slider 3. Finally, the collected waste is poured out. The model of the hydraulic cylinder 12 is CDM2B25. In this way, the use of the plastic product gate cutting equipment is completed.
