Description
Technical Field
[0001] This utility model relates to the field of pulp product molding technology, specifically an environmentally friendly pulp molding mold. Background Technology
[0002] An environmentally friendly pulp molding die is a special mold used to manufacture environmentally friendly pulp products. It is made by mixing pulp fibers with water and injecting the mixture into the mold. Utilizing the shape and structure of the mold, the pulp fibers are shaped into the desired three-dimensional shape during processes such as dewatering, drying, or hot pressing. Environmentally friendly pulp products include disposable tableware bowls. Tableware is one of people's daily necessities. With the current fast pace of life, convenient and quick disposable tableware has emerged. Disposable tableware is usually obtained by injecting raw materials into the space between a male mold and a female mold through mutual cooperation.
[0003] In existing molding dies, the male and female molds are integrated with the mold body. If damage occurs, the entire assembly needs to be replaced, increasing costs. Furthermore, existing molding dies lack an ejector structure, and directly removing the material would damage the finished product structure and affect the processing. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.
[0023] Please see Figure 1-4 This utility model provides a technical solution: an environmentally friendly pulp molding mold, including a base plate 1, a mounting frame 2 on the top surface of the base plate 1, a first mounting groove 103 and a second mounting groove 104 inside the base plate 1, the base plate 1 serving as the base of the mold, supporting the overall structure of the lower mold 3, the mounting frame 2 and the material handling mechanism 4, the first mounting groove 103 having a precision thread for fixing the lower mold 3, the second mounting groove 104 having a countersunk hole with anti-loosening thread that mates with the cylinder 301 to prevent displacement caused by vibration, the lower mold 3 being threaded into the first mounting groove 103 and the second mounting groove 104, the lower mold 3 having an arc-shaped groove 302 inside the lower mold 3, the material handling component 4 mates inside the arc-shaped groove 302.
[0024] Mounting bracket 2 has a mounting seat 5 on its top surface. A cylinder 6 is mounted on the mounting seat 5. The cylinder 6 is installed through the bottom of the mounting bracket 2. The extension end of the cylinder 6 is fitted with a mounting part 7. The mounting part 7 is threaded to fit the upper mold 8. The lower mold 3 and the upper mold 8 have built-in heating systems. At the same time, micro-holes are opened on the lower mold 3 to help drain water during pulp forming. The lower mold 3 is a pulp forming cavity with built-in heating and drainage systems. The arc groove 302 is shaped like the outer contour of a dinner bowl and is plated with hard chrome to improve wear resistance. The cylinder 301 is made of 304 stainless steel and has a lock washer at the threaded end to prevent loosening.
[0025] The mounting part 7 includes a mounting plate 701, a connecting ring 702 is mounted at the bottom of the mounting plate 701, and a threaded hole 705 is opened inside the connecting ring 702. The upper mold 8 is threadedly engaged inside the threaded hole 705.
[0026] A cylinder 301 is installed at the top of the lower mold 3. The cylinder 301 is threaded into the second mounting groove 104. The lower mold 3 is threaded into the first mounting groove 103. An assembly groove 303 is opened on the top surface of the cylinder 301. The material taking component 4 is fitted inside the assembly groove 303. The material taking component 4 includes an arc plate 401, which is fitted into the arc groove 302. Connecting plates 402 are installed at both ends of the arc plate 401, and the connecting plates 402 are fitted into the assembly groove 303.
[0027] Both ends of the bottom surface of the base plate 1 are provided with support feet 101. The support feet 101 are made of adjustable nylon feet, which have both shock absorption and leveling functions. The top surface of the base plate 1 is provided with a slot 102. The bottom end of the mounting part 7 is engaged with the slot 102. The mounting part 7 also includes a ring 704. The ring 704 is set on the bottom surface of the connecting ring 702 and engages inside the slot 102. The slot 102 is designed with a V-shaped guide groove, which forms a positioning reference with the ring 704 to ensure the closing accuracy of the upper mold. The connecting ring 702 is provided with a through hole 703. The material picking component 4 slides inside the through hole 703. The material picking component 4 also includes a pull rod 403, which is movably engaged inside the through hole 703.
[0028] When using molding dies to produce disposable bowls made from environmentally friendly pulp, the lower mold 3 is screwed into the first mounting groove 103 of the base plate 1, ensuring that the cylinder 301 is simultaneously fixed in the second mounting groove 104. The upper mold 8 is fixed to the connecting ring 702 of the mounting part 7 through the threaded hole 705. The cylinder 6 drives the mounting part 7 to move the upper mold 8 vertically. The arc plate 401 of the material taking component 4 is pre-placed in the arc groove 302 of the lower mold 3. The pull rod 403 passes through the through hole 703 of the connecting ring 702 to inject environmentally friendly pulp into the lower mold 3. The pulp needs to cover the arc plate 401. The surface is slightly higher than the groove opening to ensure uniform forming thickness. The cylinder 6 pushes the upper mold 8 down, and the ring 704 is embedded in the slot 102 of the base plate 1 to form a seal to prevent the pulp from overflowing. After the upper mold 8 and the lower mold 3 are closed, pressure is applied to the pulp, and the pulp is heated by the heating system at the same time. Under pressure, water is discharged through the mold micropores, and the pulp forms a bowl-shaped preform in the lower mold 3. After forming, the upper mold 8 is reset, and the pull rod 403 is pulled manually or mechanically to move the arc plate 401 up along the through hole 703, and the formed bowl is pushed out from the lower mold 3, making it easy to remove the material.
