Description

Technical Field

[0001] This utility model specifically relates to a multi-limiting pressing fixture for pulp molded three-dimensional products, belonging to the technical field of mold equipment for pulp molded three-dimensional products. Background Technology

[0002] Pulp molding three-dimensional products are three-dimensional structural products made primarily from plant fibers through processes such as molding and drying. They combine environmental friendliness and functionality and are widely used in packaging, home furnishings, and industry. With the diversification of functional requirements for pulp molding three-dimensional products, these products need to be produced using pressing fixtures. However, existing pressing fixtures for pulp molding three-dimensional products are mostly assembled using a single limiting method, which generally results in mediocre performance.

[0003] However, existing technologies still have the following problems:

[0004] Existing pressing fixtures for pulp molded three-dimensional products use a limiting method for pressing during mold forming, and then use bolt tightening to limit the forming. In practical applications, it is difficult to use multiple limiting methods to press the fixture together, and the efficiency of the fixture in limiting the forming is generally low. Furthermore, it is not convenient, quick, or user-friendly to disassemble the pressed fixture after forming.

[0005] To address the aforementioned problems, the inventors propose a multi-position pressing fixture for molded pulp three-dimensional products. Utility Model Content

[0006] The purpose of this utility model is to address the shortcomings of the existing technology by providing a multi-limiting pressing fixture for pulp molded three-dimensional products. This better solves the problems that pressing fixtures are difficult to combine through multiple limiting methods, have low efficiency during molding and limiting, and are not convenient and quick to disassemble.

[0007] This utility model achieves the above-mentioned objective through the following technical solution: a multi-limiting pressing fixture for pulp molded three-dimensional products, including a lower mold base, a product positioning fixture fixedly connected to the top surface of the lower mold base, a mold frame support block fixedly connected to the top surface of the lower mold base, a limit block fixedly connected to the top surface of the mold frame support block, an upper mold base provided above the lower mold base, a locking box opened on the top surface of the upper mold base, a pushing block slidably connected to the inner cavity of the locking box, a locking spring provided in the inner cavity of the locking box, a locking rod fixedly connected to one side surface of the pushing block, a locking positioning block fixedly connected to the bottom surface of the upper mold base, and a feed port penetratingly opened on the top surface of the upper mold base.

[0008] Preferably, in order to better facilitate the insertion of the positioning block into the lower mold base, the top surface of the lower mold base is provided with a positioning groove, and the positioning groove matches the structural dimensions of the positioning block.

[0009] Preferably, in order to better support the upper mold base, the number of mold frame support blocks is four, and the four mold frame support blocks are distributed at the four corners of the top surface of the lower mold base.

[0010] Preferably, in order to facilitate the insertion of the limiting block into the upper mold base, a limiting groove is formed through the top surface of the upper mold base, the limiting groove is matched with the structural size of the limiting block, and a card hole is formed through one side surface of the limiting block, which is matched with the structural size of the card rod.

[0011] Preferably, in order to better facilitate the position limitation of the limiting block, one end of the locking rod is movably connected to the locking box and located in the limiting groove, and the end of the locking rod away from the pushing block has an inclined conical surface structure.

[0012] Preferably, in order to press and push the push block, one end of the locking spring is fixedly connected to the push block, and the other end of the locking spring away from the push block is fixedly connected to the locking box.

[0013] Preferably, in order to better shield and protect the locking spring, an elastic shielding layer is fixedly connected to the inner surface of the locking box, and one end of the elastic shielding layer is fixedly connected to the push block.

[0014] Preferably, in order to better drive the movement of the push plate by the toggle lever, a toggle lever is fixedly connected to the outer surface of the push block, and the bottom surface of the toggle lever is slidably connected to the upper mold base.

[0015] The beneficial effects of this utility model are:

[0016] By setting up limit blocks, locking boxes, push blocks, locking springs, locking rods, and locking positioning blocks, when the locking positioning block under the upper mold base is inserted into the locking groove on the surface of the lower mold base, the limit block is just inserted into the limit groove at the top of the upper mold base, which precisely limits the relative position of the upper and lower mold bases. This improves the stability of the connection between the upper and lower mold bases through multiple limiting methods, and makes it very convenient and quick to separate the upper and lower mold bases after mold closing, thus improving the production efficiency of pulp molded products.

[0017] By setting mold frame support blocks at the four corners of the top surface of the lower mold base, the stability between the upper and lower mold bases is ensured when the mold is closed. After the mold is closed, there is a gap between the upper and lower mold bases near the mold frame support blocks, which facilitates the separation of the upper and lower mold bases by the operator and is more user-friendly.

Detailed Implementation

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0025] Please see Figures 1-5 As shown, a multi-limiting pressing fixture for pulp molded three-dimensional products includes a lower mold base 1, a product positioning fixture 2 fixedly connected to the top surface of the lower mold base 1, and a mold frame support block 3 fixedly connected to the top surface of the lower mold base 1. The number of mold frame support blocks 3 is four, and the four mold frame support blocks 3 are distributed at the four corners of the top surface of the lower mold base 1. The top surfaces of the four mold frame support blocks 3 are slidably connected to the upper mold base 5, which plays a supporting role for the upper mold base 5 and improves stability.

[0026] A limiting insert 4 is fixedly connected to the top surface of the mold support block 3. An upper mold base 5 is provided above the lower mold base 1. A limiting groove 13 is opened through the top surface of the upper mold base 5. The limiting groove 13 matches the structural dimensions of the limiting insert 4. A locking hole 14 matching the structural dimensions of the locking rod 9 is opened through one side surface of the limiting insert 4. The limiting insert 4 is inserted into the limiting groove 13. The locking rod 9 is inserted into the locking hole 14 on the surface of the limiting insert 4, thus limiting the limiting insert 4 in the limiting groove 13. A locking box 6 is opened on the top surface of the upper mold base 5. An elastic shielding layer 15 is fixedly connected to the inner surface of the locking box 6. One end of the elastic shielding layer 15 is fixedly connected to the push block 7. The elastic shielding layer 15 is made of rubber and serves to shield and protect the locking spring 8 inside the locking box 6.

[0027] A push block 7 is slidably fitted into the inner cavity of the positioning box 6. A toggle rod 16 is fixedly connected to the outer surface of the push block 7. The bottom surface of the toggle rod 16 is slidably connected to the upper mold base 5. The push block 7 can be moved by the toggle rod 16. A positioning spring 8 is provided in the inner cavity of the positioning box 6. One end of the positioning spring 8 is fixedly connected to the push block 7, and the other end of the positioning spring 8 away from the push block 7 is fixedly connected to the positioning box 6. When the push block 7 slides in the positioning box 6, it will compress the positioning spring 8. At this time, the positioning spring 8 will deform and generate elastic force. A locking rod 9 is fixedly connected to one side surface of the push block 7. One end of the locking rod 9 is movably connected to the positioning box 6 and is located in the limiting groove 13. The end of the locking rod 9 away from the push block 7 has an inclined conical structure. When the push block 7 moves, it will drive the locking rod 9 to move. When block 4 is inserted into the limiting groove 13, the limiting block 4 will abut against the inclined cone surface of the clamping rod 9. As the limiting block 4 enters the limiting groove 13, the clamping rod 9 and the pushing block 7 move. At this time, the clamping spring 8 is also compressed. When the limiting block 4 is fully inserted into the limiting groove 13, under the action of the clamping spring 8, the clamping rod 9 is inserted into the clamping hole 14 to limit the position of the limiting block 4. The bottom surface of the upper mold base 5 is fixedly connected with the clamping positioning block 10. The top surface of the lower mold base 1 is provided with a clamping groove 12. The clamping groove 12 matches the structural dimensions of the clamping positioning block 10. The clamping positioning block 10 is inserted into the clamping groove 12 to achieve the limiting effect and form a closed cavity on the outside of the product positioning fixture 2, which is conducive to the formation of pulp products. The top surface of the upper mold base 5 is provided with a feed port 11.

[0028] Working principle: When in use, the operator moves the upper mold base 5 downward, so that the snap-fit ​​positioning block 10 fixedly connected to the bottom surface of the upper mold base 5 gradually approaches the snap-fit ​​groove 12 opened on the top surface of the lower mold base 1. Since the snap-fit ​​groove 12 and the snap-fit ​​positioning block 10 are matched in structural size, when the snap-fit ​​positioning block 10 is fully inserted into the snap-fit ​​groove 12, the limiting plug 4 is just inserted into the limiting groove 13.

[0029] Furthermore, when the limiting block 4 is inserted into the limiting groove 13, the limiting block 4 will abut against the inclined cone surface of the locking rod 9. As the limiting block 4 enters the limiting groove 13, the locking rod 9 and the pushing block 7 move, and the locking spring 8 is also compressed. When the limiting block 4 is fully inserted into the limiting groove 13, the locking rod 9 is inserted into the locking hole 14 under the action of the locking spring 8, thus limiting the position of the limiting block 4.

[0030] Furthermore, at this time, the positioning block 10 is fully inserted into the positioning groove 12, and the limiting block 4 is limited in the limiting groove 13 by the locking rod 9. At this time, the upper mold base 5 and the lower mold base 1 are combined, and then the pulp raw material is added through the feed port 11 to form the required three-dimensional pulp product.

[0031] Furthermore, when it is necessary to separate the upper mold base 5 from the lower mold base 1, the push block 7 is moved by the toggle lever 16, and the locking lever 9 is pulled out from the locking hole 14 of the limit plug 4, thus releasing the locking relationship between the limit plug 4 and the upper mold base 5.

[0032] Furthermore, since mold support blocks 3 are provided at the four corners of the top surface of the lower mold base 1, there is a gap between the upper mold base 5 and the lower mold base 1 near the mold support blocks 3 after the mold is closed. The operator can use this gap to easily lift the upper mold base 5 upward, so that the snap-fit ​​positioning block 10 is removed from the snap-fit ​​groove 12 and the limiting insert 4 is pulled out from the limiting groove 13, thereby realizing the rapid separation of the upper mold base 5 and the lower mold base 1 and taking out the pressed pulp molded three-dimensional product.

[0033] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention.

This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
