Description

Technical Field

[0001] This utility model relates to the field of PET container production technology, specifically to a combined blow molding die. Background Technology

[0002] Blow molding molds are a type of blow molding mold. To ensure the safety of artificial respiration, they are currently mostly blown by mechanical air pumps. A robotic arm places the material into the left and right mold cavities. After the mold is closed, the blowing force can be increased, and the plastic bottle wall can be cold-formed and reinforced to fit the mold contour.

[0003] To ensure that the blown bottle structure can be removed quickly, the left and right mold cavities need to be separated. However, most of the previous PET blown bottle molds lacked reinforcement structures. The closing and opening of the mold cavity both involve the screw continuing to rotate and guiding the sliding sleeve to move due to inertia. If there are large gaps between the molds, it will affect the appearance of the bottle and increase burrs.

[0004] Now, a novel combined blow molding die is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a combined blow molding die to solve the problem of gaps in blow molding dies mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a combined blow molding die, comprising a base plate and a transverse groove. A transverse groove is provided between the two sides inside the base plate, and a lead screw is movably connected between the left and right sides of the transverse groove. A slot is provided above the transverse groove. A left threaded block is threadedly connected to the left side of the lead screw, and a right threaded block is threadedly connected to the right side of the lead screw. Ball bearings are movably embedded in the bottom of the left and right threaded blocks. A cavity is provided on the left side inside the base plate, and a worm gear is movably connected between the two sides above the cavity. A worm is movably connected between the front and rear sides below the cavity. A motor is fixed to the lower left corner of the rear of the base plate. A left module is fixed to the top of the left threaded block, and a right module is fixed to the top of the right threaded block. A plastic bottle is placed at the center of the top of the base plate.

[0007] As a further technical solution of this utility model, the front of the output end of the motor is fixedly connected to the worm gear, and the left side of the lead screw is fixedly connected to the worm wheel.

[0008] As a further technical solution of this utility model, the inner wall of the left module is provided with six sets of left spiral grooves, and a coil two is fixed inside the left spiral groove. An insert block is fixed to the right side of the coil two. The inner wall of the right module is provided with six sets of right spiral grooves, and a coil one is fixed inside the right spiral groove. A retainer is provided on the left side of the coil one. A lower valve is fixed to the lower left corner of the outer side of the left module, and an upper valve is fixed to the upper right corner of the outer side of the right module.

[0009] As a further technical solution of this utility model, the right side of the lower valve is connected to the second coil, and the left side of the upper valve is connected to the first coil.

[0010] As a further technical solution of this utility model, the left side of the right module and the right side of the left module are respectively provided with mold cavities, and the top of the mold cavity is provided with a slot. A card block is fixed in the slot, and a bolt is threadedly connected in the card block. An elastic band is fixed at the front end and the rear end of the card block respectively. A screw hole is provided at the top inside the slot.

[0011] As a further technical solution of this utility model, the bottom of the bolt is embedded in the screw hole, and the shape of the locking block matches the locking groove.

[0012] Compared with the prior art, the beneficial effects of this utility model are: this combined blow molding die not only realizes automatic mold locking and rapid cooling of the internal bottle, but also facilitates the expansion and contraction of the material entry slot;

[0013] (1) By fixing a left module at the top of the left threaded block and a right module at the top of the right threaded block, after starting the motor, the worm gear is rotated and the upper worm wheel is pushed, forcing the worm wheel to guide the screw to rotate horizontally in the transverse groove, guiding the left threaded block and the right threaded block to slide in opposite directions, forcing the upper left module and the right module to close or open, so as to close the gap or open the mold cavity for plastic raw materials to enter or leave. The worm wheel and worm gear are self-locking and reinforced to prevent the left module and the right module from sliding automatically.

[0014] (2) By fixing coil one inside the right spiral groove and coil two inside the left spiral groove, when the left module and the right module are closed, the left threaded block in the left spiral groove and the right threaded block in the right spiral groove will fit together, and the insert will be embedded in the sleeve to ensure smooth water flow. After opening the upper valve, cold water is introduced and then discharged through the lower valve to avoid the liquid splashing onto the table when the left module and the right module are separated. It can also cool the liquid through the left and right pipes after closing.

[0015] (3) Elastic bands are fixed at the front and rear ends of the card blocks respectively, and the card blocks are fixed in the card slots with bolts. As the left and right modules open, the elastic bands connected to the card blocks also open. The size of the slot above the mold cavity can be adjusted, which makes it convenient for the robotic arm to grasp the plastic raw material and probe into the mold cavity for blow molding. When closed, it wraps the air blowing pipe to avoid the reserved cavity being too large, which would cause the temperature inside the mold cavity to drop too quickly. Attached Figure Description

[0022] Please see Figure 1-4 An embodiment of this utility model provides a combined blow molding die, including a base plate 1 and a transverse groove 6. The transverse groove 6 is provided between the two sides inside the base plate 1, and a lead screw 8 is movably connected between the left and right sides inside the transverse groove 6. A slot 11 is provided above the transverse groove 6. A left threaded block 7 is threadedly connected to the left side outside the lead screw 8, and a right threaded block 10 is threadedly connected to the right side outside the lead screw 8. Ball bearings 9 are movably embedded at the bottom of the left threaded block 7 and the right threaded block 10. A cavity 2 is provided on the left side inside the base plate 1, and a worm gear 3 is movably connected between the two sides above the cavity 2. A worm 4 is movably connected between the front and back sides below the cavity 2. A motor 5 is fixed at the lower left corner behind the base plate 1. A left module 21 is fixed at the top of the left threaded block 7, and a right module 12 is fixed at the top of the right threaded block 10. A plastic bottle 25 is placed at the center of the top of the base plate 1.

[0023] The output end of motor 5 is fixedly connected to worm 4 at the front, and the left side of lead screw 8 is fixedly connected to worm wheel 3.

[0024] Specifically, such as Figure 1 and Figure 2As shown, a right module 12 is fixed at the top of the right threaded block 10. After starting the motor 5, the worm gear 4 is rotated and the upper worm wheel 3 is pushed, forcing the worm wheel 3 to guide the lead screw 8 to rotate horizontally in the transverse groove 6, guiding the left threaded block 7 and the right threaded block 10 to slide in opposite directions, forcing the upper left module 21 and the right module 12 to close or open, so as to close the gap or open the mold cavity 16 for plastic raw materials to enter or leave.

[0025] The inner wall of the left module 21 is provided with six sets of left spiral grooves 22, and a coil 23 is fixed inside the left spiral groove 22. A plug block 27 is fixed to the right side of the coil 23. The inner wall of the right module 12 is provided with six sets of right spiral grooves 13, and a coil 14 is fixed inside the right spiral groove 13. A sleeve 26 is provided on the left side of the coil 14. A lower valve 24 is fixed to the lower left corner of the outside of the left module 21. An upper valve 15 is fixed to the upper right corner of the outside of the right module 12. The right side of the lower valve 24 is connected to the coil 23, and the left side of the upper valve 15 is connected to the coil 14.

[0026] Specifically, such as Figure 1 and Figure 3 As shown, when the left module 21 and the right module 12 are closed, the left threaded block 7 in the left spiral groove 22 and the right threaded block 10 in the right spiral groove 13 fit together. The insert 27 will be embedded in the sleeve 26 to ensure smooth water flow. After opening the upper valve 15, cold water is introduced and then discharged through the lower valve 24 to prevent liquid from splashing onto the table when the left module 21 and the right module 12 are separated.

[0027] The left side of the right module 12 and the right side of the left module 21 are respectively provided with mold cavities 16, and the top of the mold cavity 16 is provided with a slot 17. A block 18 is fixed in the slot 17, and a bolt 20 is threadedly connected in the block 18. An elastic band 19 is fixed at the front end and the rear end of the block 18 respectively. A screw hole 28 is provided at the top inside the slot 17, and the bottom of the bolt 20 is embedded in the screw hole 28. The shape of the block 18 matches the slot 17.

[0028] Specifically, such as Figure 1 and Figure 4 As shown, the locking block 18 is fixed in the slot 17 with bolt 20. As the left module 21 and the right module 12 open, the elastic band 19 connected to the locking block 18 also opens, which can adjust the size of the slot above the mold cavity 16, so that the robotic arm can grasp the plastic raw material and enter the mold cavity 16 for blow molding. When closed, it wraps around the air blowing pipe for heat preservation.

[0029] Working principle: When using this invention, after starting the motor 5, the worm gear 4 rotates and pushes the upper worm wheel 3, forcing the worm wheel 3 to guide the lead screw 8 to rotate horizontally in the transverse groove 6. This guides the left threaded block 7 and the right threaded block 10 to slide in opposite directions, forcing the upper left module 21 and right module 12 to close or open. Then, the locking block 18 is fixed in the locking groove 17 with bolts 20. As the left module 21 and right module 12 open, the elastic band 19 connecting the locking block 18 also opens accordingly, which can be adjusted. The size of the slot above the mold cavity 16 is convenient for the robotic arm to grasp the plastic raw material and enter the mold cavity 16 for blow molding. When closed, it covers the air blowing pipe. When the left mold 21 and the right mold 12 are closed, the left threaded block 7 in the left spiral groove 22 and the right threaded block 10 in the right spiral groove 13 fit together. The insert 27 will be embedded in the sleeve 26 to ensure smooth water flow. After opening the upper valve 15, cold water is introduced and then discharged through the lower valve 24 to avoid liquid splashing onto the table.
