Description

Technical Field

[0001] This utility model relates to the technical field, specifically to a split-type pulp mold. Background Technology

[0002] Pulp molds are specialized tools used to shape products from pulp. The pulp is mostly made from recycled paper, wood fibers, and other processed materials. After adding appropriate amounts of adhesives and other components, it is injected into the mold. The mold can be simple, one-piece, or a two-piece design with upper and lower molds. It has injection holes, cavities, and other structures to facilitate the flow of pulp into the mold. It is commonly used to manufacture disposable tableware, packaging liners, and other products. It not only performs the shaping function, turning the pulp into the desired shape, but also meets environmental protection requirements due to its partial biodegradability and readily available raw materials. Therefore, it has a positive and wide range of applications in many fields.

[0003] Currently, most pulp molds use a split core splicing structure, such as Chinese patent CN214694902U. However, in actual use and frequent splicing, the splicing accuracy between the bases may gradually decrease due to human error, mechanical wear, or accidental collisions. This can lead to gaps at the splicing points, compromising the sealing of the hollow structure inside the core. During pulp injection, pulp may seep out from these gaps, wasting raw materials, affecting the working environment around the mold, and potentially causing surface defects in the product. Furthermore, this design is inconvenient to operate, hindering the normal use of the pulp mold. Therefore, improvements are needed. Utility Model Content

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0025] Please see Figures 1 to 6 This utility model provides a technical solution: a split pulp mold, including an upper mold 4 and a lower mold 1. The upper mold 4 is located above the lower mold 1. A cavity 21 is formed on the upper surface of the lower mold 1, and a flow channel 22 communicating with the cavity 21 is formed on the surface of the lower mold 1. A forming part 23 is fixedly connected to the lower surface of the upper mold 4, and a slurry injection pipe 5 is fixedly connected to the upper surface of the upper mold 4. An installation block 15 is fixedly connected to the surface of the lower mold 1. A rotating rod 18 is rotatably connected to the inner wall of the installation block 15. A guide rod 7 is fixedly connected to the upper end of the rotating rod 18. A sliding sleeve 9 is fixedly connected to the surface of the upper mold 4, and the sliding sleeve 9 slides against the surface of the guide rod 7. A stabilizing block 14 is fixedly connected to the guide rod 7, and a compression spring 13 is fixedly connected to the upper surface of the stabilizing block 14. The compression spring 13 is sleeved on the guide rod 7, and the upper end of the compression spring 13 is fixedly connected to the lower surface of the sliding sleeve 9. A positioning block 12 is fixedly connected to the surface of the upper mold 1, and a carrier block 17 is fixedly connected to the surface of the lower mold 1. A screw 10 is rotatably connected to the surface of the carrier block 17. One end of the screw 10 is threadedly connected to the inner wall of the positioning block 12. A torsion block 16 is fixedly connected to the screw 10. Through ingenious structural design, the guide rod 7, the sliding sleeve 9, and the cooperation of the screw 10 and the positioning block 12 are used to achieve efficient and precise positioning during the mold closing process. Operators only need to operate simply to make the upper mold 4 accurately close with the lower mold 1, ensuring a tight fit between the cavity 21 and the forming part 23. This greatly improves the dimensional accuracy and shape stability of the pulp forming product. Compared with traditional molds, it reduces the scrap rate caused by inaccurate mold closing, effectively saves production costs, and also improves production efficiency, meeting the strict requirements of large-scale industrial production for product quality consistency.

[0026] Specifically, a rotating block 20 is fixedly connected to the lower end of the rotating rod 18, and an auxiliary block 24 is fixedly connected to the side of the lower mold 1 near the mounting block 15. The rotating block 20 is rotatably connected to the inner wall of the auxiliary block 24.

[0027] Specifically, a torsion spring 19 is fixedly connected to the upper surface of the rotating block 20. The torsion spring 19 is sleeved on the rotating rod 18. The upper end of the torsion spring 19 is fixedly connected to the lower surface of the mounting block 15. The entire operation process of this solution is designed to be very convenient and flexible. From the initial installation of the mold to the preparation work before pulp injection, each step fully considers the convenience of the operator.

[0028] Specifically, a protective cover 6 is fixedly connected to the surface of the upper mold 4. The protective cover 6 is fastened to the lower mold 1. The protective cover 6 and the baffle 11 not only play a protective role after the mold is closed, preventing external impurities from entering the mold and affecting the pulp forming quality, but also increase the stability of the entire device during the operation of the mold.

[0029] Specifically, a stop 8 is fixedly connected to the upper end of the guide rod 7 to prevent the sliding sleeve 9 from detaching from the guide rod 7.

[0030] Specifically, a baffle 11 is fixedly connected to the surface of the lower mold 1. The baffle 11 is L-shaped. A support block 2 is fixedly connected to the surface of the lower mold 1. The support block 2 has mounting holes 3 on its surface to facilitate normal use of the equipment.

[0031] Working principle: Initially, the upper mold 4 and the lower mold 1 are separated. Rotating the upper mold 4 to directly above the lower mold 1 causes the upper mold 4 to rotate via the sliding sleeve 9, driving the guide rod 7 and the rotating block 20 to rotate. The torsion spring 19 deforms under pressure, at which point the protective cover 6 abuts against the stop 11. Then, pressing down on the upper mold 4 compresses the spring 13. When the screw 10 inserts into the positioning block 12, rotating the torsion block 16 causes the screw 10 to thread into the positioning block 12. Continuing to rotate the torsion block 16, until the protective cover 6 is secured to the lower mold 1, stops rotating the torsion block 16. The pulp raw material is then prepared and injected through the upper surface of the upper mold 4. Pipe 5 is connected to external grouting equipment to ensure that the pulp can be smoothly injected into the cavity 21 and the forming part 23 through the flow channel 22. After the operation is completed, the pulp is dried and cured. Then, the reverse rotation of the torsion block 16 drives the screw 10 to rotate. Then, the screw 10 pushes the positioning block 12 and the upper mold 4 upward. After the positioning block 12 is disengaged from the screw 10, the compression spring 13 pushes the sliding sleeve 9 and the upper mold 4 upward. Then, the upper mold 4 is disengaged from the lower mold 1. Then, the torsion spring 19 drives the rotating block 20, the rotating rod 18, the guide rod 7, the sliding sleeve 9 and the upper mold 4 to rotate. After the upper mold 4 is rotated away from the lower mold 1, the pulp material can be demolded.
