TECHNICAL FIELD

[0001] The utility model relates to the component structure of hydraulic vulcanizing machine, concretely is a kind of hydraulic vulcanizing machine steamer combined lower bolster plate. BACKGROUND

[0002] Tire shaping vulcanizing machine often needs to adjust the height of mold cavity according to different specifications of mold. The height adjustment of mold cavity in curing chamber can be divided into manual adjustment and electric adjustment. With the improvement of the automation degree of vulcanizing machine, the height adjustment of mold cavity in vulcanizing machine is generally electric adjustment. However, even if electric adjustment, it cannot be completely automatically adjusted, and manual adjustment and measurement of the height of mold cavity are still needed. With the continuous improvement of the intelligent, humanized and automated level requirements for tire vulcanizing machine, the traditional mold adjusting mode cannot meet the use demand, and a new mold adjusting mode is urgently needed to replace. SUMMARY

[0003] In view of the deficiencies of the prior art, the utility model provides a kind of stepless mold adjusting control device of hydraulic vulcanizing machine, the different height of mould is not needed to be considered in whole mold changing process, and stepless mold adjusting of automation can be realized, which greatly improves the mold changing efficiency of vulcanizing machine.

[0004] The utility model discloses the above-mentioned purposes are realized through the following technical schemes:

[0005] The stepless mold adjusting control device of hydraulic vulcanizing machine includes lower bolster plate, screw rod, support plate, driving device, connecting rod, switch A, switch frame, switch B and inductive ring.

[0006] The lower bolster plate is uniformly distributed with a plurality of screw rods below the circumference, and the upper end of the screw rod is fixedly connected with the support plate. The driving device can make all screw rods move up and down synchronously through transmission mechanism, and then drive the support plate to move close to or away from the lower bolster plate. The connecting rod is parallelly arranged on the screw rod by penetrating through the lower lock ring seat, and the upper end of the connecting rod is fixedly connected with the lower bolster plate. The lower end of the connecting rod is provided with switch A.

[0007] The switch frame is fixed to one side of the lower end face of the lower lock ring seat close to the connecting rod, and the switch frame is provided with switch B at the lower end.

[0008] The inductive ring is installed at the lower end of the screw rod closest to the connecting rod.

[0009] Further, the transmission mechanism includes a nut and a gear plate which are integrally arranged on the screw rod. The output end of the driving device is provided with a gear which is engaged with the gear plate.

[0010] Compared with the prior art, the utility model has the advantages and effects that:

[0011] 1. The present invention is equipped with a sensing ring that cooperates with switch A and switch B respectively, so that the rising or falling height of the screw can be steplessly adjusted and precisely controlled, thereby realizing stepless mold adjustment control of molds of any height;

[0012] 2. This invention eliminates the need for manual measurement of mold height during mold adjustment, enabling fully automated mold adjustment and replacement. This significantly reduces the labor intensity of mold replacement personnel and improves mold replacement efficiency.

[0013] 3. By setting a support plate on the screw, not only can the lifting and lowering synchronization of all screws be better, but the force on the lower support plate can also be more even. Attached Figure Description

[0016] The present invention will be further described below with reference to the embodiments, but the present invention is not limited to these embodiments.

[0017] like Figure 1 As shown, the upper end of the mold 11 is mounted on the lower end face of the upper heating plate 12, and the lower end of the mold 11 is mounted on the upper end face of the lower heating plate 13. The lower heating plate 13 is connected to the lower support plate 1 by screws. The force cylinder 14 is fixed on the lower end face of the lower locking ring seat 10. The piston rod of the force cylinder 14 is connected to the lower end face of the lower support plate 1 by screws. The lower support plate 1 and the lower heating plate 13 can move up and down under the drive of the force cylinder 14.

[0018] The stepless mold adjustment control device for the hydraulic vulcanizing machine described in this embodiment, such as Figure 1As shown, including the lower plate 1, screw 2, support plate 3, drive device 4, connecting rod 5, switch A 6, switch frame 7, switch B 8, induction ring 9, the lower plate 1 below the circumferential distribution of a plurality of screw 2, screw 2 upper end surface through the screw and support plate 3 fixedly connected, drive device 4 is fixed in the lower end surface of the lower lock ring seat 10, the drive device 4 shaft through the transmission mechanism can make all screw 2 synchronous up and down movement, in turn drive support plate 3 close to or away from the lower plate 1; connecting rod 5 through the lower lock ring seat 10 parallel to the screw 2, connecting rod 5 upper end with the lower plate 1 fixedly connected can with the lower plate 1 up and down movement, connecting rod 5 lower end is installed with switch A 6; switch frame 7 is fixed to the lower end surface of the lower lock ring seat 10 close to the side of connecting rod 5, switch frame 7 lower end is installed with switch B 8; induction ring 9 is installed in the lower end of the screw 2 closest to the connecting rod 5.

[0019] Specifically, the transmission mechanism described in the embodiment includes a nut and a gear plate which are integrally arranged on the screw 2, and a gear is arranged on the rotating shaft of the drive device 4 and engaged with the gear plate. With the rotation of the rotating shaft of the drive device 4, the nut and the gear plate on the screw 2 rotate as a whole, so that all the screws 2 move up and down synchronously, thereby driving the support plate 3 to move up and down.

[0020] The working principle of the embodiment is as follows:

[0021] 1. When the mold 11 of different height needs to be replaced, the relevant screws connected with the mold 11 are first disassembled, then the mold 11 is moved away from the vulcanizing machine through the lifting tool, and then the drive device 4 is started. The drive device 4 drives all the screws 2 to move downward synchronously through gear engagement transmission, and at the same time drives the support plate 3 to move downward, until the induction ring 9 senses the switch B 8 to be connected, and then stops. At this time, the support plate 3 is at the lowest position.

[0022] 2. The mold 11 to be replaced is mounted on the lower hot plate 13, and then the force cylinder 14 is started, so that the piston rod of the force cylinder 14 rises, the mold closing force is added, and the connecting screws between the mold 11 and the upper lock ring seat 15 are mounted. At this time, the connecting rod 5 has risen to the corresponding height (i.e. the switch A 6 also rises to the corresponding height) synchronously with the lower plate 1.

[0023] 3. The drive device 4 is started again, so that all the screws 2 rise synchronously, until the induction ring 9 at the lower end of the screw 2 senses the switch A 6 at the lower end of the connecting rod 6, and then stops. At this time, the force cylinder 14 is operated to release the pressure (i.e. the piston rod of the force cylinder 14 retracts), and the lower plate 1 is lowered to contact the support plate 3. The whole mold adjusting process is completed, and the automatic stepless mold adjusting is truly realized.
