Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to an insert locking mechanism that facilitates the assembly and disassembly of inserts. Background Technology

[0002] In the field of mold technology, inserts, also known as inserts or inserts, are mold-related terms. They are specific mold accessories designed to be embedded in the mold core and come in various shapes.

[0003] Chinese patent discloses an insert and an upper mold using the insert (patent publication number: CN203680596U). This patented technology includes an outer insert, an inner insert, fasteners, and a seal. The outer insert has an internal cavity, and the inner insert is disposed within the cavity. Fasteners pass sequentially through the inner and outer inserts to mount the outer insert onto the upper mold. The seal seals the cavity. One end of a metal part is inserted between the inner and outer inserts, while the other end of the metal part is positioned outside the cavity. The metal part is fixed by pressing against the inner insert and the seal. The upper mold includes a mold frame and inserts, with at least one insert mounted on the mold frame. Its advantages include: convenient installation of the metal part, easy cleaning of the PU adhesive inside the insert, and improved production efficiency.

[0004] This patented technology facilitates the cleaning of materials inside the insert during use, but it still has shortcomings. It still uses mounting holes and bolts for installation, requiring additional installation tools, which makes the installation and removal of the insert time-consuming and inconvenient. To address these issues, we propose an insert locking mechanism that facilitates the installation and removal of the insert. Utility Model Content

[0005] The purpose of this invention is to address the problems existing in the background art by proposing an insert locking mechanism that facilitates the assembly and disassembly of inserts.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an insert locking mechanism for easy assembly and disassembly of inserts, comprising a mold, an insert body, a top shaft, and a fixed shaft. One end of the insert body is provided with a toothed plate slidably installed inside the mold. The fixed shaft is rotatably installed inside the mold. A gear meshing with the toothed plate is provided at the upper end of the fixed shaft. A sliding sleeve is embedded inside the mold. A top shaft is slidably inserted inside the sliding sleeve. One end of the top shaft is provided with a retaining seat. An installation shaft is rotatably installed inside the retaining seat. One end of the installation shaft is provided with a retaining block. The outer wall of the fixed shaft has grooves arranged in a circular array that engage with the retaining blocks. A torsion spring is sleeved on the outer wall of the installation shaft, with both ends connected to the retaining block and the retaining seat respectively. One end of the retaining seat is provided with a support spring connected to the inner wall of the mold and sleeved on the outer side of the top shaft.

[0007] When using the insert locking mechanism in this solution, which facilitates the installation and removal of inserts, the toothed plate of the insert body slides into the mold. The guide rail at the rear end of the toothed plate is slidably supported by the slide block. The toothed plate is slidably installed inside the insert body and is slidably guided. During this process, one end of the toothed plate pushes the gear, thereby driving the fixed shaft to rotate. The fixed shaft drives the gear to rotate. When the fixed shaft rotates, it pushes the locking block through the slot on the outer wall. The locking block is then supported by the mounting shaft and pushed to rotate. At the same time, the torsional support force of the torsion spring acts on the locking block, allowing the locking block to continuously move in different slots. Meanwhile, the limiting block limits one end of the locking block to prevent reverse rotation of the locking block. After insertion, the toothed plate is fixed and locked, thus realizing the installation of the insert body.

[0008] Preferably, an adjustment groove corresponding to the sliding sleeve is formed on one side of the outer wall of the mold, and a stroke groove is formed on the upper inner wall of the adjustment groove. A pull handle located inside the adjustment groove is provided at one end of the top shaft. Gripping the pull handle facilitates the application of pulling force to the top shaft, and the pull handle and one end of the top shaft move inside the adjustment groove.

[0009] Preferably, a positioning groove is provided inside the upper end of the top shaft, and a positioning block with its lower end inserted into the positioning groove is slidably installed inside the stroke groove. A lifting block is provided at one end of the positioning block. The positioning block is held by the lifting block, which facilitates the application of longitudinal force to the positioning block. After the positioning block is inserted into the positioning groove, it locks the top shaft in place.

[0010] Preferably, the upper end of the positioning block is provided with a positioning spring that connects to the inner wall of the upper end of the travel groove. During use, the positioning spring applies an elastic supporting force to the upper end of the positioning block, so that the positioning block inserted into the positioning groove is elastically positioned.

[0011] Preferably, a limiting block is fixed to one side of the inner wall of the mold, located on one side of the locking block. The limiting block limits one end of the locking block to prevent that end of the locking block from rotating in the opposite direction.

[0012] Preferably, a guide rail is provided on one side of the inner wall of the mold, and a slider is provided at one end of the toothed plate, with one end of the slider slidably mounted inside the guide rail. The insert body slides inside the guide rail via the slider, thus guiding the insert body.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. The insert body of this utility model is slidably installed with the mold via an insert plate. After the toothed plate is inserted into the mold, the toothed plate pushes the gear to drive the fixed shaft to rotate. The slot on the outer wall of the fixed shaft moves the elastic support block, and the block can only rotate in one direction. The insert body is directly fixed after insertion. During the use of the mold, when the insert body is disassembled, the elastic adjustment block is also used to disengage from the slot, releasing the situation of the fixed shaft being locked in one direction. The insert body is convenient and time-saving to disassemble and assemble. Attached Figure Description

[0021] 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.

[0022] like Figures 1-5 As shown, the present invention proposes an insert locking mechanism that facilitates the assembly and disassembly of inserts, including a mold 1, an insert body 3, a top shaft 4, and a fixed shaft 7. One end of the insert body 3 is provided with a toothed plate 9 that is slidably installed inside the mold 1. The fixed shaft 7 is rotatably installed inside the mold 1. The upper end of the fixed shaft 7 is provided with a gear 8 that meshes with the toothed plate 9. A sliding sleeve 15 is embedded inside the mold 1. The top shaft 4 is slidably inserted inside the sliding sleeve 15. One end of the top shaft 4 is provided with a retainer 6. An installation shaft 18 is rotatably installed inside the retainer 6. One end of the installation shaft 18 is provided with a retaining block 13. The outer wall of the fixed shaft 7 is provided with retaining grooves 12 arranged in a ring array and engaging with the retaining block 13. The outer wall of the installation shaft 18 is sleeved with a torsion spring 17 whose two ends are respectively connected to the retaining block 13 and the retaining block 6. One end of the retaining block 6 is provided with a support spring 5 that is connected to the inner wall of the mold 1 and sleeved on the outside of the top shaft 4.

[0023] A guide rail 10 is provided on one side of the inner wall of the mold 1, and a slider 11 is provided on one end of the toothed plate 9. One end of the slider 11 is slidably installed inside the guide rail 10.

[0024] Based on the implementation steps of Embodiment 1: A stroke port is provided at the installation location of the mold 1 and the toothed plate 9. The toothed plate 9 is inserted into the guide rail 10 through the stroke port. The insert body 3 is inserted into the mold 1. When the toothed plate 9 moves, the rack at one end of the toothed plate 9 pushes the gear 8. Through the rotational support of the fixed shaft 7, the stroke force acts on the fixed shaft 7, and the fixed shaft 7 rotates. The locking block 13 is locked in the slot 12. The fixed shaft 7 drives the slot 12 to rotate, and the inner wall of the slot 12 squeezes the locking block 13. When the locking block 13 rotates around the mounting shaft 18, the locking block 13 is pushed. Through the torsional elastic support of the mounting shaft 18 by the torsion spring 17, the locking block 13, which is separated from the slot 12, achieves elastic reset and enters the next slot 12. At the same time, the limiting block 23 limits one end of the locking block 13 to prevent the locking block 13 from rotating in the opposite direction. The toothed plate 9 inserted into the mold 1 is locked. The installation process avoids the use of additional tools, thereby realizing the convenient installation of the insert body 3.

[0025] like Figures 1-5 As shown, the insert locking mechanism proposed in this utility model, which facilitates the assembly and disassembly of inserts, is further provided in this embodiment than in embodiment one: an adjustment groove 2 corresponding to the sliding sleeve 15 is provided on the outer wall of one side of the mold 1, a stroke groove 22 is provided on the inner wall of the upper end of the adjustment groove 2, and a pull handle 14 located inside the adjustment groove 2 is provided at one end of the top shaft 4.

[0026] The top shaft 4 has a positioning groove 19 inside its upper end. A positioning block 16 with its lower end inserted into the positioning groove 19 is slidably installed inside the stroke groove 22. A lifting block 20 is provided at one end of the positioning block 16.

[0027] The upper end of the positioning block 16 is provided with a positioning spring 21 that is connected to the inner wall of the upper end of the stroke groove 22;

[0028] A limiting block 23 located on one side of the clamping block 13 is fixed to the inner wall of one side of the mold 1;

[0029] In this embodiment, when the insert body 3 is disassembled, the lifting block 20 applies upward force to drive the positioning block 16 to move upward, squeezing the positioning spring 21. The gripping handle 14 drives the top shaft 4 to move laterally, and the pulling force is transmitted to the card seat 6. The support spring 5 is compressed under force. It is worth noting that the elasticity of the support spring 5 is several times that of the torsion spring 17, ensuring the stability of the card seat 6 during use. Therefore, the force required to pull the top shaft 4 is relatively large, and it is relatively difficult to pull. At the same time as the support spring 5 contracts, the card seat 6 moves, driving the card block 13 to move out of the card slot 12. The fixed shaft 7 loses its lock, thereby realizing the movement of the insert body 3 and the toothed plate 9. When the insert body 3 is disassembled, the use of additional tools is avoided through the preset elastic structure, and the insert body 3 can be easily disassembled.

[0030] The above specific embodiments are merely several preferred embodiments of this utility model. Based on the technical solution of this utility model and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.

[0031] 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. No reference numerals in the claims should be construed as limiting the scope of the claims.
