Reference numerals

The die comprises a base 1, a stop flange 2, a lower die 3, a connecting shaft 4, a stop flange 5, an upper die 6, a middle die 7, a cross beam 8, a hydraulic cylinder 9, a groove 10, a spiral spring 11 and a hydraulic cylinder 12.

Detailed Description

Referring to fig. 1, the upper mold 6 and the middle mold 7 are fastened to form a vulcanization cavity, and the lower mold 3 and the middle mold 7 are fastened to form another vulcanization cavity. The mold is buckled to form a vulcanization inner cavity, which belongs to the prior art and is not described again here. The technical improvement point of the invention is that two hydraulic cylinders are adopted for driving, so that the upper die, the middle die and the lower die are sequentially buckled to form the two vulcanizing cavities in one action process of the hydraulic cylinders.

Referring to fig. 1, in order to realize linkage of three molds, a linkage structure is formed by at least two connecting shafts, in fig. 1, one embodiment uses two connecting shafts, such as a left connecting shaft 4, taking the connecting shaft 4 as an example, the connecting shaft 4 penetrates through an upper mold 6, a middle mold 7 and a lower mold 3, a stop flange 2 and a stop flange 5 are arranged on the connecting shaft, the stop flange 2 is located below the middle mold 7, and the stop flange 2 is used for suspending the middle mold 7 on the connecting shaft 4. The stop flange 5 is located above the upper mould 6. The function of the stop flange 5 is to suspend the connecting shaft 4 from the upper mould 6. Where the connecting shaft contacts the bottom of the middle mold 7, a groove 10 (see fig. 2) is formed, and the stopper flange 2 can be completely inserted into the groove 10. So that the stop flange 2 does not affect the snap-fit of the middle and lower molds.

As shown in fig. 1, the lower mold 3 is fixed on the base 1, and a hole or other structures should be reserved on the fixing base 1 in order to enable the connecting shaft to freely move up and down.

As shown in fig. 1 and 3, fig. 1 is a state before mold clamping, and fig. 3 is a state after mold clamping. The process of die assembly is that the hydraulic cylinder 9 and the hydraulic cylinder 12 which are hoisted on the beam 8 drive the upper die 6 to move downwards, the connecting shaft 4 moves downwards under the action of the gravity of the connecting shaft and the load on the connecting shaft, and the middle die 7 moves downwards under the action of the gravity until the middle die 7 is buckled on the lower die 3; the upper mold 6 continues to move downwards until the upper mold 6 is buckled on the middle mold 7, and the two hydraulic cylinders apply proper pressure to tightly buckle the three molds together, as shown in fig. 3.

Referring to fig. 4, in order to prevent the dies from being damaged due to excessive pressing between the dies, a coil spring is sleeved on the connecting shaft, and still taking the connecting shaft 4 as an example, a coil spring 11 is sleeved on the connecting shaft 4, and the coil spring 11 is located between the lower die 3 and the base 1. The spiral spring plays a role in buffering, and extrusion damage between the dies is effectively avoided.
