Motorbike tire segmental mold structure for plate vulcanizing machine

Abstract

The invention discloses a motorbike tire segmental mold structure for a plate vulcanizing machine. The structure is composed of an upper cover plate, an upper cover, an upper side plate, a T-shaped block, a pattern block, a guide bar, a pattern block locking wedge, a pedestal, a distance determining rod, an order pull rod and an order pull rod limiting device. The pattern block locking wedge is asingle block structure and embedded in the upper cover plate for locating; the distance determining rod is fixed on the upper cover plate and passes through the upper cover, when primary mold openingis executed, the distance determining rod guides, limits and supports the upper cover; the T-shaped block is connected above the pattern block through a bolt, and can move radially in a T-shaped blockgroove of the upper cover; the pattern block is connected with the pattern block locking wedge through the guide bar; the order pull rod is fixed on the pedestal; and a semicircular groove is designed at a head part of the order pull rod and cooperates with a spring pin in the order pull rod limiting device to play a role in secondary mold opening. The mold structure provided by the invention realizes segmental mold movement actions on a tire shaping vulcanizer, and can make the plate vulcanizing machine perform vulcanizing production for a meridian motorbike tire.

Description

technical field [0001] The invention relates to a tire mold structure, in particular to a motorcycle tire active mold structure device for a flat vulcanizer. Background technique [0002] At present, motorcycle tires are mostly bias tires, which are vulcanized and formed by using a flat vulcanizing machine through two halves of the mold. With the development of high-end motorcycles, the performance requirements for motorcycle tires are getting higher and higher, and radial tires have the advantages of good wear resistance, small frictional resistance, large load-bearing capacity, and good cushioning performance. Motorcycles equipped with radial tires The car handles well and feels great to drive. The two halves of the mold are divided up and down, and the active mold is divided into multiple pattern blocks radially. This structure mainly eliminates the damage to the tire cord angle and spacing when the two halves of the mold are opened, ensuring the quality and performance ...

AI Technical Summary

Problems solved by technology

The elastic force of the spring will cause elastic failure during the long-term use of the mold, which will affect the opening and closing of the mold

[0007] 3. According to the description of the prior art, the radial movement stroke of the slider 6 is limited by the limit block 401 on the middle mold sleeve, that is to say, when the mold is opened, the weight of the slider, the pattern block and the upper cover are all determined by this The limit block bears, which poses a great safety hazard

[0008] 4. According to the description of the prior art, when the mold is opened, the middle mold cover 4 rises, and the first elastic member 11 and the second elastic member 8 apply continuous downward elastic force to press the upper cover and remain still. Due to the insufficient spring force Stability (while the spring in the prior art does not add a spring support rod), it is very easy to cause the uneven force of the upper cover, so that the upper cover is inclined to cause the instability of the slider 6 movement, and sometimes even cause The guide bar 5 on the slider 6 and the guide groove on the middle mold sleeve 4 are stuck, so that the mold cannot be opened and closed
