The connecting member 53321 includes at least a third gear 44, and the third gear 44 is connected to the piston rod 50. The third gear 44 is meshed with the gear ring 41. When the intermediate seat 12 rotates, the engagement between the third gear 44 of the connecting member 53321 and the gear ring 41 can control the movement of the piston rod 50 in the exhaust pipe 40.

[0029] In another specific case of the present embodiment, the connecting member 53321 includes a connecting plate 42, a lifting shaft 45, a clamping shaft 43, a ratchet group 46, a matching block 48, a clamping seat 49 and a positioning sub-component, wherein the connecting plate 42 is arranged on the intermediate seat 12, the clamping shaft 43 is movably arranged on the connecting plate 42 and is slidably clamped with the threaded rod 28, the third gear 44 is movably arranged on the connecting plate 42 and is concentrically arranged with the clamping shaft 43, the matching block 48 is arranged on the third gear 44, the lifting shaft 45 is movably arranged on the side of the third gear 44 away from the clamping shaft 43, the lifting shaft 45 is connected to the clamping shaft 43, the clamping seat 49 is arranged on the lifting shaft 45 and cooperates with the matching block 48, the ratchet group 46 is arranged between the lifting shaft 45 and the clamping seat 49, and the positioning sub-component is arranged between the lifting shaft 45 and the guide ring 39 for adjusting the position of the lifting shaft 45.

Under the action of the push arm 36, the second rack 37 can be driven to reciprocate. Under the meshing action between the second rack 37 and the second gear 38, the second gear 38 and the intermediate seat 12 are driven to rotate repeatedly, thereby realizing the continuous switching of the position of the cavity 9 on both sides of the intermediate seat 12. In this process, the connecting plate 42 and the third gear 44 can be driven to rotate synchronously. Under the interference action of the adjustment ring 51 and the lifting shaft 45, the lifting shaft 45 and the card seat 49 can be driven to move downward. At this time, the card seat 49 is connected to the matching block 48. Although the third gear 44 is meshed with the gear ring 41, due to the setting of the ratchet group 46, When the middle seat 12 is rotated to adjust the position of the first layer of injection molded parts, the clamping shaft 43 is in a static state. When the middle seat 12 is reset, the third gear 44 can be rotated. The third gear 44 drives the lifting shaft 45 and the clamping shaft 43 to rotate, thereby driving the piston rod 50 to rotate.

In the actual process, by setting a torsion spring between the clamping shaft 43 and the connecting plate 42, the resetting work of the cylinder 18 and the piston rod 50 can be controlled.

[0032] See also Figure 1-Figure 10 As another preferred embodiment of the present application, the dust collection module 55 includes a threaded rod 28, a differential 26, a first gear 27, a first rack 20, a rotating arm 21, a sliding column 23, a dust collection seat 25 and an air pump 31. The threaded rod 28 is movably arranged in the protective shell 8. A guide plate 24 is arranged on the support plate 3. The dust collection seat 25 is movably arranged on the guide plate 24 and threadedly cooperates with the threaded rod 28. The first gear 27 is movably arranged in the protective shell 8 and is connected to the threaded rod 28 through the differential 26.

The air pump 31 is arranged on the top seat 2 and is connected to the dust collection seat 25 through the bellows 32.

[0033] In the process of controlling the repeated rotation of the middle seat 12, the rotating arm 21 can be driven to swing repeatedly. Under the sliding cooperation between the sliding column 23 and the through groove 22, the first rack 20 can be driven to reciprocate relative to the base 1, and then under the meshing action between the first rack 20 and the first gear 27, the first gear 27 is driven to rotate, and then under the action of the differential 26, the threaded rod 28 is driven to rotate. Under the threaded cooperation between the threaded rod 28 and the dust suction seat 25, the dust suction seat 25 is driven to reciprocate in the vertical direction along the guide plate 24, thereby adjusting the position of the dust suction seat 25, and at the same time, it can drive the air pump 31 to work. When the air pump 31 is working, it can control the dust suction seat 25 to suck in the dust in front of it, so that when the middle seat 12 drives the cavity 9 and the injection molded parts in the cavity 9 to rotate, the dust on the surface of the injection molded parts in the cavity 9 is cleaned through the dust suction seat 25 to avoid affecting the second-layer injection molding.

[0034] How this application works: By installing the cores on the two injection molding machines on the mounting frames 6 on both sides of the middle seat 12 respectively, and controlling the operation of the injection molding machine to drive the core to move and connect with the cavity 9, the molten rubber can be injected into the cavity 9 and the core for molding through the operation of the injection molding machine, and then the injection molding machine controls the core and cavity 9 to open the mold to complete the molding of the first layer of injection molded parts, and by controlling the electric telescopic rod 33 to continuously extend and retract, the lifting head 35 can be driven to reciprocate relative to the mounting platform 34, and under the action of the push arm 36, the second rack 37 can be driven to reciprocate, and under the meshing action between the second rack 37 and the second gear 38, the second gear 38 and the middle seat 12 are driven to rotate repeatedly, thereby realizing the continuous switching of the position of the cavity 9 on both sides of the middle seat 12, and in this process, the connecting plate 42 and the third gear 44 can be driven to rotate synchronously, and the positioning ring 51 and the lifting shaft can be adjusted. Under the interference of 45, the lifting shaft 45 and the card seat 49 can be driven to move downward. At this time, the card seat 49 and the matching block 48 are connected. Although the third gear 44 and the gear ring 41 are meshed, due to the setting of the ratchet group 46, when the intermediate seat 12 is rotated to adjust the position of the first layer of injection molded parts, the card shaft 43 is in a static state. When the intermediate seat 12 is reset, the third gear 44 can be rotated at this time. The third gear 44 drives the lifting shaft 45 and the card shaft 43 to rotate, thereby driving the piston rod 50 to rotate. Under the action of the threaded cooperation between the piston rod 50 and the exhaust pipe 40, the piston rod 50 is controlled to rotate while moving along the exhaust pipe 40, so that the air in the cylinder 18 is extracted along the air pipe 14, and the cylinder 18 is controlled to shrink, thereby adjusting the position of the push seat 17. Under the action of the push rod 19, the connecting sleeve 16 and the ejector rod 13 can be controlled as Figure 6 The state shown is moved upward, thereby ejecting the molded injection molded part from the mold cavity 9. In the actual process, by arranging a torsion spring between the clamping shaft 43 and the connecting plate 42, the reset work of the cylinder 18 and the piston rod 50 can be controlled. In the process of controlling the repeated rotation of the middle seat 12, the rotating arm 21 can be driven to swing repeatedly. Under the sliding cooperation between the sliding column 23 and the through groove 22, the first rack 20 can be driven to reciprocate relative to the base 1, and then under the meshing action between the first rack 20 and the first gear 27, the first gear 27 is driven to rotate, and then under the action of the differential 26, the threaded rod 28 is driven to rotate. Under the threaded cooperation between the threaded rod 28 and the dust suction seat 25, the dust suction seat 25 is driven to reciprocate in the vertical direction along the guide plate 24, thereby adjusting the position of the dust suction seat 25, and at the same time, it can drive the air pump 31 to work. When the air pump 31 is working, it can control the dust suction seat 25 to suck in the dust in front of it, so that when the middle seat 12 drives the cavity 9 and the injection molded parts in the cavity 9 to rotate, the dust on the surface of the injection molded parts in the cavity 9 is cleaned through the dust suction seat 25 to avoid affecting the second-layer injection molding.
