Description

Technical Field

[0001] This utility model relates to the technical field of plastic cup production equipment, specifically to an injection mold for producing plastic cups. Background Technology

[0002] Plastic cups are disposable containers used to hold beverages and tea. They are mostly cylindrical with an opening at the top and are hollow to hold the contents. An injection mold is a tool used in the plastic injection molding process. By injecting heated and molten plastic into the mold cavity, the finished product is obtained after cooling and solidification. Plastic cups require the use of injection molds for production.

[0003] Existing patent CN221089811U discloses a plastic cup injection mold, belonging to the field of injection molds. It includes an upper mold body, a lower mold body, and an injection port. The upper and lower mold bodies are fitted together. The injection port is located at the upper end of the upper mold body. The lower mold body has multiple molding shells, each with an injection molding chamber for forming the plastic cup at its upper end. The lower end of the lower mold body has a cavity, within which a spiral cooling pipe is fitted onto the molding shell. A sealing bottom cover is located at the bottom of the cavity, with a sloping groove at its upper end and a drain outlet at the bottom of the groove. The spiral cooling pipes on the plastic cup mold enable rapid cooling of the plastic cup, facilitating demolding. The sealing bottom cover at the bottom of the spiral cooling pipe chamber, with its sloping groove, allows condensate to slide out quickly, and the drain outlet further improves cooling efficiency.

[0004] Based on the above patent search and combined with the existing injection mold technology, it was found that although the current injection molds for producing plastic cups can be used to produce plastic cups, the molded plastic cups need to be handled manually, which is dangerous and reduces their practicality.

The first motor drives the lead screw to rotate, which in turn drives the slider to move vertically, which in turn moves the plastic cup upward, causing it to detach from the lower mold. The second motor drives the drive shaft to rotate, which in turn drives the plastic cup to rotate, causing it to fall into the collection box. This allows for quick material handling without manual handling, reducing the risk of material handling and greatly improving practicality.

[0016] 2. By incorporating a stripping component, the cylinder can push the moving plate to move vertically. The moving plate, in turn, drives the moving rod and the drive plate to move vertically. The drive plate, in turn, drives the stripping plate to move vertically. The moving stripping plate can eject the molded plastic cup, allowing it to be quickly demolded and preventing the plastic cup from becoming stuck. The elasticity of the spring can also protect the plastic cup from damage, thereby further improving its practicality. Attached Figure Description

[0026] Working principle: During operation, the hydraulic cylinder 81 is activated, pushing the upper mold 82 downward to close with the lower mold 11, completing the injection molding of the plastic cup. After injection molding, the upper mold 82 resets. At this time, the pneumatic cylinder 43 is activated, pushing the moving plate 44 upward. The movement of the moving plate 44 drives the moving rod 45, which in turn drives the drive plate 46. The drive plate 46 then drives the stripper plate 50, which lifts the molded plastic cup. Spring 49 protects the plastic cup from damage. The resetting of the cylinder 43 resets the stripper plate 50. Then, the second motor 51 is activated, driving the drive shaft 52 to rotate. The rotation of the drive shaft 52 drives the rotating seat 21, which in turn drives the vertical plate 22 to rotate. The device can rotate the horizontal plate 25 and the suction cover 26, causing the suction cover 26 to rotate to the top of the plastic cup. The vacuum pump 27 is activated, which can suction the plastic cup. The first motor 31 is activated, which can drive the lead screw 30 to rotate. The rotation of the lead screw 30 can drive the slider 24 to move upward. The slider 24 can drive the horizontal plate 25 to move upward, which in turn can drive the plastic cup to move upward, causing it to detach from the lower mold 11. The second motor 51 rotates in the opposite direction, which can drive the suction cover 26 to reset, causing it to rotate to the top of the collection box 91. The vacuum pump 27 is turned off, and the plastic cup falls into the collection box 91, completing the removal of the plastic cup. Repeating the above operation can produce and remove plastic cups in batches. The above is the working process of the entire device. All contents not described in detail in this specification are existing technologies known to those skilled in the art.
