Description

A self-lubricating plastic bottle blow molding die structure design device Technical Field

[0001] This utility model relates to the field of blow molding die structure design technology, and in particular to a self-lubricating plastic bottle blow molding die structure design device. Background Technology

[0002] The design and development of mold structures requires the use of equipment or instruments with specific functions. For example, some mold design and manufacturing companies may use specialized mold structure analysis and simulation devices, which can simulate and analyze the stress, deformation, cooling and other aspects of the mold to help designers optimize the mold structure, identify and solve potential design problems in advance, and ensure the reliability and stability of the mold in actual production.

[0003] When conducting mold structure analysis and simulation, multiple sets of different samples are often produced first and then tested using a blow molding machine. During the experiment, different molds need to be changed frequently for testing. However, existing blow molding machines mostly use cylinders and hydraulic rods to drive two molds to blow mold together, which makes changing molds cumbersome and inconvenient, greatly affecting the efficiency of the experiment.

[0004] Therefore, we propose a self-lubricating plastic bottle blow molding die structure design device to solve the above problems. Summary of the Invention

The four magnetic suction columns are respectively adapted to the corresponding magnetic suction holes, which facilitates the limiting of the corresponding molds.

[0010] Specifically, the combined mechanism includes a linkage base, a first crank, a linkage component, and a transmission component. The linkage base is slidably installed on the inner side of the device port. Linkage slots are provided on both sides of the linkage base.

Linkage components are provided at one end of the two first cranks. Transmission components are provided on one side of the two linkage components.

[0011] Specifically, the linkage component includes a linkage column, a fixed column, and an L-shaped crank. A fixed column is fixedly installed on the bottom inner wall of the equipment port. An L-shaped crank is rotatably sleeved on the fixed column. An auxiliary groove is opened at one end of the L-shaped crank. A linkage column is fixedly installed on the bottom inner wall of the auxiliary groove. The first crank is rotatably sleeved on the linkage column.

[0012] Specifically, the transmission assembly includes a connecting column, a second crank, and a transmission column. A transmission groove is provided on one side of the linkage metal block. A transmission column is fixedly installed on the bottom inner wall of the transmission groove. The second crank is rotatably sleeved on the transmission column.

The other end of the active rod is fixedly connected to one side of the linkage base, and the linkage base can be moved by the active rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: the set combination mechanism can make it easier to replace the mold, and at the same time can stably drive the mold to combine and blow mold, which is convenient for staff to conduct multiple experiments. In addition, the mold is equipped with self-lubricating material, which can facilitate the demolding of blow molded parts and prevent damage to blow molded parts from affecting the experimental results.

[0022] In this embodiment, the main mold 2 is detachably equipped with a blow molding head 4 and a blow molding base 5, which can be quickly replaced.

[0023] In this embodiment, the inner sides of both the main mold 2 and the auxiliary mold 3 are provided with multiple demolding grooves, and the inner sides of the multiple demolding grooves are filled with polytetrafluoroethylene blocks 6 to facilitate self-lubricating demolding.

[0024] In this embodiment, two magnetic suction columns 8 are fixedly installed on the side of the two linked metal blocks 7 that are close to each other, and magnetic suction holes are opened on the side of the main mold 2 and the auxiliary mold 3 that are far apart from each other. The four magnetic suction columns 8 are respectively adapted to the corresponding magnetic suction holes, which facilitates the limiting of the corresponding molds.

[0025] In this embodiment, the combined mechanism includes a linkage base 11, a first crank 12, a linkage component, and a transmission component. The linkage base 11 is slidably installed on the inner side of the equipment port. Linkage slots are provided on both sides of the linkage base 11. Columnar protrusions are provided on the bottom inner walls of the two linkage slots. The first crank 12 is rotatably sleeved on the two columnar protrusions. A linkage component is provided at one end of each of the two first cranks 12. A transmission component is provided on one side of each of the two linkage components.

[0026] In this embodiment, the linkage component includes a linkage column 13, a fixed column 15, and an L-shaped crank 14. The fixed column 15 is fixedly installed on the bottom inner wall of the equipment port. The L-shaped crank 14 is rotatably sleeved on the fixed column 15. An auxiliary groove is opened at one end of the L-shaped crank 14. The linkage column 13 is fixedly installed on the bottom inner wall of the auxiliary groove. The first crank 12 is rotatably sleeved on the linkage column 13.

[0027] In this embodiment, the transmission assembly includes a connecting column 16, a second crank 17, and a transmission column 18. A transmission groove is provided on one side of the linkage metal block 7. The transmission column 18 is fixedly installed on the bottom inner wall of the transmission groove. The second crank 17 is rotatably sleeved on the transmission column 18. A connecting groove is provided at the other end of the L-shaped crank 14. The connecting column 16 is fixedly installed on the bottom inner wall of the connecting groove. The second crank 17 is rotatably sleeved on the connecting column 16.

The other end of the active rod 10 is fixedly connected to one side of the linkage base 11, and the linkage base 11 can be moved by the active rod 10.

[0029] Working principle: During the experiment, the operator assembles the blow molding head 4 and blow molding base 5 with the main mold 2. Then, the operator aligns the two magnetic holes on one side of the main mold 2 and the auxiliary mold 3 with the corresponding two magnetic posts 8. The four magnetic posts 8 slide into their corresponding magnetic holes, allowing the linkage metal block 7 to move the corresponding mold through magnetic attraction. During the experiment, the operator activates the cylinder 9. The activation of cylinder 9 moves the drive rod 10, which in turn moves the linkage base 11. The movement of the linkage base 11 then moves the two linkage posts 13, which in turn move the two linkage posts 13. The corresponding first crank 12 moves, and the movement of the two first cranks 12 drives the corresponding L-shaped crank 14 to move. However, the two L-shaped cranks 14 are both rotated and sleeved on the corresponding fixed column 15. Therefore, the two L-shaped cranks 14 can only rotate around the corresponding fixed column 15 as the center. The rotation of the two L-shaped cranks 14 drives the corresponding connecting column 16 to move. The movement of the two connecting columns 16 drives the corresponding second crank 17 to move. The movement of the two second cranks 17 drives the corresponding transmission column 18 to move, which in turn drives the corresponding linkage metal block 7 to move, so that the main mold 2 and the auxiliary mold 3 can be combined. Then, a blow molding experiment can be carried out.

[0030] The technological advancements of this invention compared to existing technologies are: it allows for more convenient mold replacement, and can stably drive the mold to be assembled and blow-molded, facilitating multiple experiments for staff. Furthermore, the mold contains self-lubricating material, which facilitates demolding of the blow-molded parts and prevents damage to the blow-molded parts from affecting the experimental results.
