Description

Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a mold. Background Art

[0002] Tire vulcanization refers to the vulcanization of the outer tire, which is vulcanized by model pressurization. The characteristic is that the outer diameter of the outer tire is smaller than the inner diameter of the model. During vulcanization, the tire is filled with a water tire or a capsule, and high-pressure hot water is added to the water tire. The expansion pressure of the water tire or the capsule is used to fill the outer tire with the model. The outer tire vulcanization adopts a gradual temperature increase and low-temperature long-term vulcanization method to allow the rubber to fully flow and transfer heat to ensure the quality of vulcanization. The original small-sized bias tire molds are all vulcanized using water tires in a four-column vulcanizer, and it is inconvenient for the tire to be separated from the mold after vulcanization. Therefore, improvements are needed. Utility Model Content

The connecting sleeve is driven by the cylinder to move, thereby causing the oblique block to move and squeeze the oblique ring, so that the oblique ring drives the push rod upward, thereby causing the push plate to slide in the lower mold, thereby facilitating the tire to be ejected from the lower mold for demoulding after molding.

[0006] Preferably, the push rod is slidably connected to the steel ring, the push rod is slidably connected to the backing plate, and the push rod is slidably connected to the lower mold. By setting the push rod, the movement of the push plate is controlled.

[0007] Preferably, a top plate is welded to the upper end of the push rod, and the top plate is slidably connected to the lower mold. By providing the top plate, the product can be easily fixed after being formed.

[0008] Preferably, one end of the spring is welded to the mounting plate, and the other end of the spring is welded to the connecting ring. By providing the spring, the connecting ring is easy to reset.

[0009] Preferably, a limit pin is slidably connected in the connecting sleeve, and the limit pin and the cylinder rod are connected by threads. The connecting sleeve and the cylinder rod are connected by setting the limit pin.

[0010] The beneficial effects of the utility model are as follows:

[0011] 1. The utility model drives the connecting sleeve to move through the cylinder, so that the inclined block moves to squeeze the inclined ring, so that the inclined ring drives the ejector rod to move upward, so that the ejector plate slides in the lower mold, so that after the tire is formed, it is easy to eject it from the lower mold for demoulding.

[0012] 2. The utility model processes the connecting thread between the clamp and the center mechanism onto the steel ring, and at the same time processes the steel ring to raise the mold so that the clamp is higher than the center mechanism, thereby avoiding interference between the clamp and the center mechanism during the installation of some small-sized molds, and solving the problem that the mold cannot be installed due to restrictions on the vulcanizing bladder and the vulcanizing machine model. At the same time, the mold is changed from four-column to automatic vulcanizing machine production, which reduces the labor intensity of workers and improves production efficiency.
