Description

Technical Field

[0001] This utility model relates to the field of mechanical engineering technology, specifically to an automatic mold pressing and opening production line. Background Technology

[0002] Compression molding is a key process in manufacturing that transforms raw materials into shaped products. The production of products such as plastic shells, rubber seals, and metal structural parts all rely on this process. Its core process consists of mold closing, material injection or pressurization, pressure holding and shaping, mold opening, and part removal. In recent years, with the continuous development of downstream industries such as automobiles, electronics, and home appliances, these industries have increasingly higher requirements for product precision, while also paying more attention to improving production efficiency and the stability of product quality during mass production. Against this backdrop, the traditional compression molding production model has gradually revealed many technical shortcomings, which have become key issues limiting capacity expansion and affecting product quality. While existing technologies meet user needs to a certain extent, certain shortcomings still exist during use. Specific problems are as follows: Traditional molding equipment is mostly a stand-alone operation mode, requiring manual completion of processes such as "workpiece transfer, mold alignment, mold closing triggering, and mold opening and part removal." Manual operation is slow and cannot achieve 24-hour continuous operation. Daily production capacity is insufficient to meet the needs of mass production, requiring dedicated personnel to operate each machine. Large-scale production requires a large investment of manpower, and manual operation is susceptible to fatigue and experience limitations, leading to unstable process rhythm. Based on this, this utility model designs an automatic molding and mold opening production line to solve the above problems. Summary of the Invention

[0013] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0014] Example: Figure 1-4As shown, this utility model provides a technical solution: an automatic mold opening production line, including a circular track 1. Several sets of mold opening equipment bodies 2 are mounted on the surface of the circular track 1. Each mold opening equipment body 2 includes an equipment support 3. A first hinge seat 4 is symmetrically fixedly connected to the surface of the equipment support 3. A cylinder 5 is rotatably connected to the surface of the first hinge seat 4. A second hinge seat 6 is symmetrically fixedly connected to the surface of the equipment support 3. A second connecting rod 7 is rotatably connected to the surface of the second hinge seat 6. The end of the second connecting rod 7 away from the second hinge seat 6 is fixed. The upper mold mounting bracket 8 is connected, and the surface of the upper mold mounting bracket 8 is fixedly connected to the mold driving bracket 9. The surface of the mold driving bracket 9 is fixedly connected to the driving connecting seat 10. The end of the cylinder 5 away from the first hinge seat 4 is rotatably connected to the driving connecting seat 10. The surface of the upper mold mounting bracket 8 is provided with an upper mold 11. The lower mold mounting seat 12 is provided below the upper mold 11 and is fixedly connected to the surface of the equipment bracket 3. The surface of the lower mold mounting seat 12 is provided with a lower mold 13. The surface of the upper mold 11 is provided with an injection port 14.

[0015] In this implementation scheme: the circular track 1 carries multiple sets of mold opening and closing equipment bodies 2 for cyclic rotation. In a single set of equipment, one end of the cylinder 5 is rotatably connected to the first hinge seat 4, and the other end is rotatably connected to the drive connecting seat 10. When the cylinder 5 extends or retracts, it drives the mold drive frame 9 through the drive connecting seat 10. Combined with the rotatable connection between the second connecting rod 7 and the second hinge seat 6, a linkage transmission mechanism is formed, which causes the upper mold mounting frame 8 to drive the upper mold 11 to approach or move away from the lower mold 13 on the lower mold mounting seat 12, thus completing the mold closing or opening. The injection port 14 is used to inject molding material into the cavity after mold closing. The circular track 1 realizes the assembly line operation of multiple sets of equipment, improving production efficiency. The cylinder 5 and the connecting rod cooperate to realize automatic mold closing and opening, ensuring the accuracy of the action. The injection port 14 is adapted to the mold feeding requirements.

[0016] Furthermore: In an optional embodiment, the surface of the lower mold mounting base 12 is provided with a lower mold positioning groove 15 that cooperates with the lower mold 13.

[0017] In this embodiment, the lower mold positioning groove 15 on the surface of the lower mold mounting base 12 matches the outer shape of the lower mold 13, accurately positioning the lower mold 13 in the horizontal direction and avoiding misalignment of the cavity when the mold is closed.

[0018] Furthermore: In an optional embodiment, the surface of the upper mold mounting bracket 8 is provided with an upper mold positioning groove 16 that mates with the upper mold 11. The surface of the upper mold 11 is fixedly connected with four sets of upper mold locking ears 17. The surface of the upper mold locking ears 17 is slidably connected with an upper mold locking pin 18. The surface of the upper mold mounting bracket 8 is provided with an upper mold locking hole 19 that mates with the upper mold locking pin 18. The surface of the upper mold locking pin 18 is threadedly connected with a locking nut 20.

[0019] In this embodiment: the upper mold positioning groove 16 of the upper mold mounting bracket 8 initially positions the upper mold 11, the upper mold locking pin 18 slides into the upper mold locking hole 19 along the upper mold locking ear 17, and the locking nut 20 is tightened to fix the upper mold 11 on the upper mold mounting bracket 8 to prevent loosening when the mold is closed / opened, and to facilitate disassembly and maintenance.

[0020] Furthermore: In an optional embodiment, four sets of lower mold locking ears 21 that cooperate with the upper mold locking ears 17 are fixedly connected to the surface of the lower mold 13. The lower mold locking ears 21 are slidably connected to the surface of the lower mold locking pins 22. The surface of the lower mold mounting base 12 is provided with locking thread grooves 23 that cooperate with the lower mold locking pins 22.

[0021] In this embodiment: when the lower mold 13's lower mold locking ear 21 and the upper mold locking ear 17 are closed, the lower mold locking pin 22 slides along the lower mold locking ear 21 and is screwed into the locking thread groove 23 of the lower mold mounting base 12 to fix the lower mold 13, which facilitates the disassembly and maintenance of the lower mold 13.

[0022] Furthermore: In an optional embodiment, a clearance groove 24 is provided on the opposite side of the lower mold locking ear 21 and the upper mold locking ear 17.

[0023] In this embodiment: during mold closing, in order to avoid collisions and motion interference between the upper mold locking pin 18 and the lower mold locking pin 22, or between the upper mold locking ear 17 and the lower mold locking ear 21 during the mold closing / opening process, a clearance groove 24 is provided on the opposite side of the lower mold locking ear 21 and the upper mold locking ear 17 to provide clearance space for the movement trajectory or installation position of the upper mold locking pin 18 and the lower mold locking pin 22, and to ensure smooth mold closing and opening operations.

[0024] Furthermore: In an optional embodiment, a fixing seat 25 is symmetrically fixedly connected to the surface of the lower mold mounting base 12, and a support block 26 is fixedly connected to the surface of the fixing seat 25. The support block 26 is matched with the shape of the lower mold 13.

[0025] In this embodiment: the fixed base 25 is symmetrically fixed to the surface of the lower mold mounting base 12, and the support block 26 fixedly connected to its surface is adapted to the shape of the lower mold mounting base 12. Through the fit and support of the lower mold mounting base 12, it provides structural support force for the lower mold mounting base 12.
