Description

Technical Field

[0001] This utility model relates to the field of mold-related technology, specifically to a modular split mold. Background Technology

[0002] Modular, split-type molds exhibit significant advantages in the manufacturing industry due to their unique design concept. By replacing or recombining modules, they can be quickly adapted to different product specifications, making them particularly suitable for multi-variety, small-batch production needs. When product design changes, only the relevant modules need to be adjusted, without the need to redevelop the entire mold, thus shortening the R&D cycle. Multiple products can share core modules, reducing the cost of repeated mold development. In case of partial damage, only the faulty module needs to be replaced, avoiding the scrapping of the entire mold and reducing long-term usage costs.

[0003] Chinese patent application CN202222196561.6, entitled "A Split-Type Modular Mold," discloses a split-type modular mold, including a mold body. The lower wall of the mold body has x placement slots, where x is a non-zero natural number. The upper wall of the mold body has threaded grooves, the number of which matches the number of placement slots. The positions of the threaded grooves correspond to the positions of the placement slots, and the threaded grooves communicate with the inner cavities of the placement slots. A mold module is inserted and installed within each placement slot. The upper wall of each mold module has a threaded hole, and a bolt is rotatably installed within the threaded groove. The bolt is rotatably installed in the threaded hole.

[0004] However, the aforementioned patent has the following shortcomings: Assembling the sub-mold onto the mold body using several bolts requires an alternating, step-by-step, synchronous tightening strategy when connecting two parts. This ensures the uniformity, stability, and reliability of the connection. If a single bolt is fully tightened before processing adjacent bolts, the first bolt to be tightened may bear excessive preload, potentially causing subsequent bolts to fail to reach the expected tension. Alternating tightening gradually balances the load on each bolt, preventing localized stress concentration. When the sub-mold is damaged or needs to produce other similar products, it must be replaced. Therefore, using several bolts to assemble the sub-mold leads to low efficiency during replacement. Thus, a modular, split-type mold design is needed. Utility Model Content

[0005] In view of the above-mentioned technical problems, the purpose of this utility model is to overcome the problem of low efficiency when changing the mold in the prior art.

[0006] To achieve the above objectives, this utility model provides a modular split mold, comprising: a mold body with at least one mounting groove on the bottom wall, each mounting groove having a protruding sub-mold detachably assembled therein via a mounting unit, at least one vertical first through groove being provided through the top of the mounting groove, and a positioning rod that can be inserted upward into the first through groove being assembled on the top of the sub-mold.

[0007] The mounting unit includes at least one set of connecting mechanisms that can be detachably engaged with the upper end of the positioning rod and at least one first mounting bolt that can pass through the connecting mechanisms and be threadedly connected to the mold. The top of the mounting groove is provided with a second through groove for the first mounting bolt to pass through.

[0008] Preferably, the connecting mechanism includes a connecting rod that can be detachably snapped onto the upper end of the positioning rod, a connecting piece connected to the top of the connecting rod, at least one cam that is horizontally rotatably connected to the connecting piece and can contact the top of the mold body, and a rocker arm that is fixedly connected to the cam. The rocker arm is provided with a strip-shaped through groove of the same length direction for the first mounting bolt to pass through.

[0009] The head of the first mounting bolt can press against the uppermost rocker arm, and the lowermost rocker arm is in contact with the top of the mold body.

[0010] Preferably, the number of cams is a pair, with the pair of cams located on both sides of the connector and both fixedly connected to the rocker arm.

[0011] Preferably, the top of the positioning rod has a cylindrical portion with a diameter smaller than that of the positioning rod, which protrudes coaxially from the top of the cylindrical portion. A limiting disk protrudes coaxially from the top of the cylindrical portion. The diameter of the limiting disk is larger than that of the cylindrical portion but smaller than that of the positioning rod. The limiting disk has a notch.

[0012] The outer wall of the positioning rod is in contact with the inner wall of the first through groove. The side of the connecting rod away from the axis of the positioning rod can slide against the side wall of the first through groove. The side of the connecting rod close to the axis of the positioning rod can slide against the side wall of the limiting plate. The lower end of the connecting rod is provided with a locking block that can pass through the notch and abut against the lower surface of the limiting plate.

[0013] Preferably, the top of the mold is recessed with a mounting hole for inserting the lower end of the positioning rod, and the side wall of the mold is provided with a mounting groove communicating with the mounting hole. A second mounting bolt capable of passing through the lower end of the positioning rod is fitted on the mounting groove.

[0014] Preferably, the bottom edge of the card block is provided with a chamfer.

[0015] According to the above technical solution, the modular split mold provided by this utility model has the following beneficial effects in use:

[0016] Firstly, during assembly, the sub-mold is inserted into the mounting groove, and the positioning rod is also inserted into the corresponding first through groove. At this time, the connecting mechanism is engaged with the corresponding connecting rod, which can prevent the sub-mold from falling out of the mounting groove. This facilitates the threaded assembly of the first mounting bolt on the top of the first sub-mold. Only one first mounting bolt is needed to complete the assembly, reducing the difficulty of operation and improving the assembly efficiency.

[0017] Secondly, when installing the sub-mold, the positioning rod and the first through groove facilitate the quick positioning of the sub-mold. When the top of the sub-mold is rectangular or regular polygonal, there are multiple ways to put the sub-mold into the installation groove. The positioning rod can quickly and correctly position and assemble the sub-mold in the installation groove.

[0018] Other features and advantages of this utility model will be described in detail in the following detailed description section; and all parts not covered in this utility model are the same as or can be implemented using existing technology. Attached Figure Description

[0026] The specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are for illustration and explanation only and are not intended to limit the scope of this utility model.

[0027] In this utility model, unless otherwise stated, directional words such as "upper," "lower," "inner," and "outer" included in the terminology only represent the orientation of the term in its conventional use or are common terms understood by those skilled in the art, and should not be regarded as limitations on the term.

[0028] like Figure 1-4 As shown, a modular split mold includes: a mold body 1 with at least one mounting groove on the bottom wall, a protruding sub-mold 2 detachably assembled in each mounting groove via an mounting unit, at least one vertical first through groove 3 penetrating through the top of the mounting groove, and a positioning rod 4 that can be inserted upward into the first through groove 3 on the top of the sub-mold 2.

[0029] The installation unit includes at least one set of connecting mechanisms that can be detachably engaged with the upper end of the positioning rod 4 and at least one first mounting bolt 5 that can pass through the connecting mechanisms and be threadedly connected to the mold 2. A second through groove is provided through the top of the installation groove for the first mounting bolt 5 to pass through.

[0030] In the above technical method, when disassembling and installing the mold 2, the positioning rod 4 and the first through groove 3 facilitate the quick positioning of the mold 2. When the top of the mold 2 is rectangular or regular polygonal, the mold 2 can be placed into the mounting groove in multiple ways. The positioning rod 4 can quickly make the mold 2 correctly positioned and assembled in the mounting groove.

[0031] During disassembly, simply loosen and remove the first mounting bolt 5, then separate the connecting mechanism from the corresponding positioning rod 4 to disassemble the mold 2. By reducing the number of first mounting bolts 5, the efficiency of disassembly can be improved. During assembly, the mold 2 is inserted into the mounting groove, and the positioning rod 4 is also inserted into the corresponding first through groove 3. At this time, the connecting mechanism is engaged with the corresponding connecting rod 6 to prevent the mold 2 from falling out of the mounting groove. This facilitates the threaded assembly of the first mounting bolt 5 on the top of the mold 2, reducing the difficulty of operation and improving assembly efficiency. After the first mounting bolt 5 is assembled, both the first mounting bolt 5 and the positioning rod 4 can apply an upward pulling force to the mold 2. The assembly of the mold 2 can be completed with the assistance of one first mounting bolt 5 and several connecting mechanisms. As a minimum, only one first mounting bolt 5 is needed to complete the assembly. The operation is simple and convenient, and it can improve the efficiency of assembly and disassembly.

[0032] In a preferred embodiment of the present invention, the connecting mechanism includes a connecting rod 6 that can be detachably snapped onto the upper end of the positioning rod 4, a connecting piece 7 connected to the top of the connecting rod 6, at least one cam 8 that is horizontally rotatably connected to the connecting piece 7 and can contact the top of the mold body 1, and a rocker arm 9 that is fixedly connected to the cam 8. The rocker arm 9 is provided with a strip-shaped through groove 10 of the same length direction for the first mounting bolt 5 to pass through.

[0033] The head of the first mounting bolt 5 can press against the uppermost rocker arm 9, and the lowermost rocker arm 9 is in contact with the top of the mold body 1.

[0034] In the above technical method, during the assembly of the mold 2, the upper end of the connecting rod 6 is engaged with the positioning rod 4, the rocker arm 9 is rotated and the cam 8 is driven to rotate. The cam 8 abuts against the top of the mold body 1, which can pull the positioning rod 4 to move upward, so that the mold 2 fits into the mounting groove. Then, the first mounting bolt 5 is passed through the strip groove 10 on several rocker arms 9. Several rocker arms 9 are stacked together, and the head of the first mounting bolt 5 will be tightly pressed on the rocker arm 9 located at the top.

[0035] After the first mounting bolt 5 is assembled, the part mold 2 will exert a downward pulling force on the first mounting bolt 5 due to its own weight. If the part mold 2 tends to fall downward, an upward force will be applied to the head of the first bolt through the connecting mechanism. The first mounting bolt 5 is subjected to two opposite forces, which can not only play a role in preventing loosening, but also improve the installation firmness of the part mold 2.

[0036] In a preferred embodiment of this utility model, the number of cams 8 is a pair, and the pair of cams 8 are located on both sides of the connector 7 and are fixedly connected to the rocker arm 9.

[0037] In the above technical method, a pair of cams 8 are located at both ends of the connector 7, so that the connector 7 is subjected to uniform force and avoids the problem of uneven force and skewing that occurs when there is only one cam 8.

[0038] In a preferred embodiment of the present invention, a cylindrical portion 11 with a diameter smaller than that of the positioning rod 4 is coaxially protruding from the top of the positioning rod 4, and a limiting disk 12 with a diameter larger than that of the cylindrical portion 11 and smaller than that of the positioning rod 4 is coaxially protruding from the top of the cylindrical portion 11. The limiting disk 12 has a notch.

[0039] The outer wall of the positioning rod 4 is in contact with the inner wall of the first through groove 3. The side of the connecting rod 6 away from the axis of the positioning rod 4 can slide against the side wall of the first through groove 3. The side of the connecting rod 6 close to the axis of the positioning rod 4 can slide against the side wall of the limiting plate 12. The lower end of the connecting rod 6 is provided with a locking block 13 that can pass through the notch and abut against the lower surface of the limiting plate 12.

[0040] In the above-mentioned technical method, after the positioning rod 4 is inserted into the first through groove 3, the locking block 13 is inserted into the notch and moved to the bottom of the limiting plate 12. Then the connecting rod 6 is rotated so that the locking block 13 is misaligned with the notch. The locking block 13 can then abut against the lower surface of the limiting plate 12, thereby applying an upward pulling force to the positioning rod 4.

[0041] In a preferred embodiment of the present invention, the top of the mold 2 is recessed with an installation hole for inserting the lower end of the positioning rod 4, and the side wall of the mold 2 is provided with an installation through groove communicating with the installation hole. A second installation bolt 14 that can pass through the lower end of the positioning rod 4 is fitted on the installation through groove.

[0042] In the above-mentioned technical method, when it is necessary to replace the positioning rod 4, the second mounting bolt 14 is loosened and removed, and the positioning rod 4 can be pulled out from the mounting hole. A new positioning rod 4 can be installed, or positioning rods 4 of different lengths can be installed, so that the mold 2 can be assembled on different mold bodies 1. The positioning rod 4 is then fixed in place by the second mounting bolt 14. The operation of replacing the positioning rod 4 is simple and convenient.

[0043] In a preferred embodiment of this utility model, the bottom edge of the locking block 13 is provided with a chamfered portion.

[0044] In the above-mentioned technical method, the chamfered part is conducive to the movement of the locking part 13 through the notch to the bottom of the limiting plate 12.

[0045] The preferred embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the specific details of the above embodiments. Within the scope of the technical concept of the present invention, various simple modifications can be made to the technical solution of the present invention, and these simple modifications all fall within the protection scope of the present invention.

[0046] It should also be noted that the various specific technical features described in the above specific embodiments can be combined in any suitable way without contradiction. In order to avoid unnecessary repetition, this utility model will not describe the various possible combinations separately.

[0047] Furthermore, various different embodiments of this utility model can be combined in any way, as long as they do not violate the spirit of this utility model, they should also be regarded as the content disclosed by this utility model.
