Description

Technical Field

[0001] This utility model belongs to the field of mold design technology, and in particular relates to a high-efficiency mold with quick component replacement. Background Technology

[0002] A mold is a tool used in industrial production to process raw materials (such as metals, plastics, rubber, etc.) into specific shapes and sizes through processes such as machining, injection molding, and casting. The function of a mold is to precisely control the flow, cooling, and molding process of raw materials through its internal or external cavities, ejector pins, gates, and other structures, thereby producing the required parts or products. Molds are widely used in many industries such as automobiles, electronics, home appliances, and packaging, and are key tools for achieving large-scale production and high-precision processing.

[0003] Existing molds still have some problems during use. For example, when molding different raw materials, it is necessary to frequently change the cavity inside the mold. Current mold designs usually require multiple steps to change the cavity, and the process usually requires changing the cavities of the upper and lower molds separately. More complicatedly, since the ejection structure cannot be effectively used to change the mold cavity, this further leads to the cumbersome process and extended downtime. Such operations not only increase production downtime but also negatively impact the working efficiency of the mold, especially in production environments that require frequent adjustments to the mold configuration.

[0004] To address these issues, we provide a highly efficient mold with quick component replacement. Utility Model Content

[0005] The purpose of this invention is to provide a high-efficiency mold with quickly replaceable components. By combining the replacement components and the lifting components, the invention solves the problem of low efficiency in replacing cavity components in existing molds, which affects the working efficiency of the mold.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a high-efficiency mold with quickly replaceable components, comprising a base, a top frame fixedly connected to the top of the base, a lower mold fixedly connected to the top of the base, and an upper mold disposed at the bottom of the top frame; a replacement component is disposed at the bottom of the top frame, the replacement component comprising an upper mounting plate disposed at the bottom of the top frame, an upper cavity plate slidably connected to the inner cavity of the upper mold, inclined blocks slidably connected to both sides of the inner cavity of the upper mounting plate, and an upper insert rod fixedly connected to one side of the inclined blocks, the replacement component being used to replace mold components; a lifting component is disposed in the inner cavity of the base, the lifting component comprising a first cylinder fixedly connected to both sides of the inner cavity of the base, a lower mounting plate fixedly connected to the free end of the first cylinder, and a lower cavity plate slidably connected to the inner cavity of the lower mold, the lifting component being used to remove the molded object in the lower mold and to release the limiting position of the cavity plate.

[0008] The present invention is further configured such that a first spring is fixedly connected to both sides of the top of the upper mounting plate, a sloping panel is fixedly connected to one end of the first spring, one side of the sloping panel contacts one side of the sloping block, and a top block is fixedly connected to one side of the sloping panel.

[0009] The present invention is further configured such that a lower insertion rod is slidably connected to both sides of the inner cavity of the lower mounting plate, and a second spring is sleeved on one side of the surface of the lower insertion rod, with one end of the second spring fixedly connected to one side of the lower mounting plate.

[0010] The present invention is further configured such that limit blocks are fixedly connected to both sides of the bottom of the upper mounting plate, and a third spring is sleeved on the surface of the upper insertion rod. One end of the third spring is fixedly connected to one side of the limit block, and the other end of the third spring is fixedly connected to one side of the inclined block.

[0011] The present invention is further configured such that mounting blocks are fixedly connected to both sides of the bottom of the lower cavity plate, and mounting openings are provided on both sides of the inner cavity of the lower mounting plate, and the surface of the mounting block is slidably connected to the inner cavity of the mounting opening.

[0012] The present invention is further configured such that round holes are provided on the top of both sides of the upper cavity plate, and the inner cavity of the round holes is slidably connected to one end of the upper insertion rod.

[0013] The present invention is further configured such that a second cylinder is fixedly connected to the top of the top frame, and the free end of the second cylinder is fixedly connected to the top of the upper mounting plate.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model uses a first cylinder to drive the lower mounting plate downwards, which, in conjunction with a second cylinder, causes the upper and lower molds to close. This causes the top of the lower mold to press against the top block, pushing the inclined panel upwards. Then, the first spring's resetting action causes the upper insert rod to disengage from the upper cavity plate, achieving rapid disassembly of the upper cavity plate. Simultaneously, the first cylinder lifts the lower mounting plate, which can cause the lower cavity plate to separate from the lower mold. The second spring's elasticity causes the lower insert rod to disengage from the mounting block, completing the disassembly of the lower cavity plate. This design simplifies the traditional multi-step disassembly and assembly process and significantly improves the efficiency of cavity replacement.

[0016] 2. This utility model achieves dual-purpose operation of a single cylinder through two motion modes of the first cylinder. During normal production, the first cylinder drives the lower mounting plate to move within a limited stroke. At this time, the lower insert rod maintains a stable limit on the lower cavity plate under the action of the second spring, ensuring the overall stability of the mold structure when the molded part is ejected. When it is necessary to change the cavity, the first cylinder can perform an additional stroke, driving the lower mounting plate to continue moving upward, so that the lower insert rod is completely separated from the mounting block, realizing the rapid release of the lower cavity plate. This design not only simplifies the complex structure brought about by the independent ejection mechanism and disassembly mechanism in traditional molds, but also ensures the accuracy of the operation sequence through mechanical linkage, avoiding errors that may be caused by manual intervention, and significantly reducing the equipment modification cost and maintenance difficulty.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0025] The technical solutions of the present utility model will be described below with reference to the accompanying drawings. The described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0026] Example 1

[0027] Please see Figures 1-5 This utility model is a high-efficiency mold with quick-change components, including a base 1, with heat dissipation vents on both sides of the base 1, and dustproof nets fixedly connected to the inner cavities of the heat dissipation vents. A top frame 2 is fixedly connected to the top of the base 1, and a lower mold 3 is fixedly connected to the top of the base 1. An upper mold 4 is set at the bottom of the top frame 2. The top of the upper mold 4 and the bottom of the upper mounting plate 5 are fixedly connected. The inner cavity of the lower mold 3 can fit against the surface of the upper mold 4, so that the upper mold 4 and the lower mold 3 can be pressed together to complete the molding work. A replacement component is set at the bottom of the top frame 2. The replacement component includes an upper mounting plate 5 set at the bottom of the top frame 2. An installation groove is opened in the bottom of the upper mounting plate 5, so that the top of the upper cavity plate 6 can extend into the installation groove for easy installation and disassembly. The upper cavity plate 6 is slidably connected to the inner cavity of the upper mold 4. Inclined blocks 7 are slidably connected to both sides of the inner cavity of the upper mounting plate 5. Each component is fixedly connected to a limiting strip, the surface of which is slidably connected to the bottom of the inclined block 7 to limit the inclined block 7. An upper insert rod 8 is fixedly connected to one side of the inclined block 7, one end of which is inserted into one side of the inner cavity of the upper cavity plate 6 for mounting the upper cavity plate 6. The upper cavity plate 6 can be replaced by changing the mold assembly. A lifting assembly is provided inside the base 1 cavity. The lifting assembly includes a first cylinder 9 fixedly connected to both sides of the inner cavity of the base 1. The first cylinder 9 is used to move the lower mounting plate 10 to facilitate ejection and demolding, and to separate the lower cavity plate 11 from the lower mold 3, causing the lower insert rod 15 to separate from the lower cavity plate 11, thus completing the removal of the lower cavity plate 11. The lower mounting plate 10 is fixedly connected to the free end of the first cylinder 9, and the lower cavity plate 11 is slidably connected to the inner cavity of the lower mold 3. The lifting assembly is used to remove the molded object from the lower mold 3 and release the limiting of the cavity plate.

[0028] Example 2

[0029] Please see Figures 1-5Based on Embodiment 1, a first spring 12 is fixedly connected to both sides of the top of the upper mounting plate 5. The first spring 12 is used to drive the inclined plate 13 and the receiving block 14 to reset, and can also limit the movement of the two. One end of the first spring 12 is fixedly connected to the inclined plate 13, one side of the inclined plate 13 contacts one side of the inclined block 7, and one side of the inclined plate 13 is fixedly connected to the receiving block 14. The bottom of the upper mounting plate 5 has sliding grooves on both sides, and the surface of the receiving block 14 is slidably connected to the inner cavity of the sliding groove. The lower mounting plate 10 has a lower insertion rod 15 slidably connected to both sides of the inner cavity. One end of the lower insertion rod 15 is inclined so that it can be reset by the first cylinder 9 after being separated from the lower mold 3. A second spring 16 is sleeved on one side of the surface of the lower insertion rod 15. The second spring 16 can drive the lower insertion rod 15 to reset. One end of the second spring 16 is fixedly connected to one side of the lower mounting plate 10. Limiting blocks 17 are fixedly connected to both sides of the bottom of the upper mounting plate 5. The limiting block 17 can limit the upper insertion rod 8 and drive the upper insertion rod 8 to reset through the third spring 18 to complete the installation. The surface of the upper insertion rod 8 is fitted with the third spring 18. One end of the third spring 18 is fixedly connected to one side of the limiting block 17, and the other end of the third spring 18 is fixedly connected to one side of the inclined block 7. The bottom sides of the lower cavity plate 11 are fixedly connected with mounting blocks 19. The inner cavity of the mounting block 19 has a circular hole to facilitate the insertion of the lower insertion rod 15 to complete the replacement of the lower cavity plate 11. The inner sides of the lower mounting plate 10 have mounting openings. The surface of the mounting block 19 is slidably connected to the inner cavity of the mounting opening. The top of both sides of the upper cavity plate 6 has a circular hole. The inner cavity of the circular hole is slidably connected to one end of the upper insertion rod 8. The top of the top frame 2 is fixedly connected with the second cylinder 20. The second cylinder 20 can drive the upper mold 4 to move to facilitate the molding between the upper mold 4 and the lower mold 3. The free end of the second cylinder 20 is fixedly connected to the top of the upper mounting plate 5.

[0030] The working principle of this utility model is as follows: First, the second cylinder 20 drives the upper mounting plate 5 to move the upper mold 4 down and close with the lower mold 3. At this time, the top of the lower mold 3 fits with the top of the ejector block 14 to complete the product molding. When demolding, the first cylinder 9 pushes the lower mounting plate 10 up to push the lower cavity plate 11 out of the molded part. At the same time, the lower insert rod 15 is locked to the mounting block 19 under the action of the second spring 16. When it is necessary to change the cavity, the first cylinder 9 first drives the lower mounting plate 10 and the lower cavity plate 11 down a certain distance. Then, the second cylinder 20 drives the upper mold 4 to close again, so that the ejector block 14 is pressed and pushes the inclined block 7 to move laterally through the inclined plate 13, which drives the upper insert rod 8 to overcome the tension of the third spring 18 and disengage from the round hole of the upper cavity plate 6. Immediately afterwards, the first cylinder 9... The lower mounting plate 10 is moved to its limit position, causing the lower insertion rod 15 to disengage from the mounting block 19 and unlocking the lower cavity plate 11. At this time, the upper and lower cavity plates 11 can be removed simultaneously. After replacing the new cavity plate, the first cylinder 9 returns and drives the lower insertion rod 15 to automatically engage with the new mounting block 19 under the guidance of the inclined surface. At the same time, when the upper mold 4 rises, the first spring 12 pushes the inclined panel 13 to reset, and the third spring 18 pulls the inclined block 7 to insert the upper insertion rod 8 into the new upper cavity plate 6, completing the rapid replacement. The entire process, through the coordinated action of the sequential cylinder action and the spring reset mechanism, realizes the fully automated operation from product molding, demolding to cavity replacement. It optimizes the traditional multi-step disassembly and assembly process that requires manual intervention into a highly efficient mechanical linkage system, significantly reducing production downtime and manual operation intensity.

Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
