A hydraulic vulcanizing machine mold adjusting force device and hydraulic vulcanizing machine

Abstract

The invention discloses a die adjustment and force application device for a hydraulic vulcanizing machine, and a hydraulic vulcanizing machine. The die adjustment and force application device for the hydraulic vulcanizing machine comprises an upper support plate, wherein the top of the upper support plate is connected with a die opening-closing oil cylinder at the top of a main machine frame; a segmented die oil cylinder and a lower support seat are arranged at the top of the upper support plate, the segmented die oil cylinder is connected with a segmented die, the lower support seat is arranged around the segmented die oil cylinder, a die adjustment and force application oil cylinder is connected to the top of the lower support seat, and a force application ejection rod is connected to the top of the die adjustment and force application oil cylinder. The die adjustment and force application device for the hydraulic vulcanizing machine further comprises a force application ejection plate, wherein the force application ejection plate is connected with an air cylinder, and the force application ejection plate is capable of horizontally moving with the horizontal telescoping of the air cylinder; the force application ejection plate is removed out to be staggered with the force application ejection rod during die opening of the hydraulic vulcanizing machine; and the force application ejection plate is returned and the force application ejection rod is abutted against the force application ejection plate during die closing of the hydraulic vulcanizing machine. The die adjustment and force application device for the hydraulic vulcanizing machine enables die adjustment and force application to realize drive through one oil cylinder, is simpler in structure and simple and convenient to operate, reduces the machining and manufacturing cost, and improves the equipment performance.

Description

technical field [0001] The invention relates to the technical field of tire machinery, in particular to a mold adjusting force device for a hydraulic vulcanizer and a hydraulic vulcanizer. Background technique [0002] The hydraulic vulcanizing press is the equipment used to complete the last process of tire production, and is the key equipment to determine the quality of tires. The more common frame-type hydraulic vulcanizing machine consists of a main engine frame, afterburner cylinder, afterburner column, afterburner top plate, upper support plate, etc. to form a closed force system, which is used to ensure the tensile force required for tire vulcanization. It is the typical structural feature of the frame-type hydraulic vulcanizing machine. When it works: the tire is placed in the curing chamber, the curing chamber is fixed on the upper pallet, and the movable mold cylinder is installed on the upper pallet. The movable mold cylinder is used for tire pattern forming. Mol...

Problems solved by technology

In this method of mold adjustment through thread pairs, since the mold adjustment nut is fixed to the booster column, the mold adjustment nut needs to be driven by the booster cylinder connected to the booster column. However, this will not only make the mold adjustment Errors in the height will weaken the force strength of the mold-adjusting studs, and will also increase the fit gap in the thread pair, making it easier for impurities to enter; or it may be difficult to adjust due to the sintering of lubricating oil

In addition, the frame of the frame-type hydraulic vulcanizing machine needs to bear all the reaction force of clamping mold, and the force deformation is large, so the strength of the fuselage needs to be strengthened, resulting in a serious increase in manufacturing costs
