Tire mold pore machining device and method

Abstract

The invention discloses a tire mold air hole processing device and a processing method. The air hole processing device includes a workbench, a swing plate, an axial swing block of a pattern block, a servo motor, a rotating shaft, and a circumferential swing block of a pattern block. The swing plate is installed on the pattern block. On the block axial swing block, the pattern block axial swing block is connected with the rotating shaft, the rotating shaft is connected with the servo motor transmission, and the pattern block circumferential swing block is installed on the swing plate. The axial swing block and the circumferential swing block of the pattern block are used to realize the swing of the pattern block in the axial direction and the circumferential direction, the swing is flexible, and the normal direction of the air hole position of the pattern block is guaranteed. The swing angle range is large, and the servo The motor controls the axial swing, and the swing angle is precisely adjustable.

Description

technical field [0001] The invention relates to the field of tire mold processing, in particular to a tire mold air hole processing device and processing method. Background technique [0002] Tire mold air holes are used for venting during vulcanization of tires, and the location consistency requirements are relatively high. If the positions and diameters of the air holes are inconsistent, the vulcanized tire lanugo will not be arranged in a standardized manner, and the appearance will not be beautiful. Especially in the inter-tire position of the pattern block, due to the large arc at this position, it is very difficult to process the air holes normal to the arc surface. [0003] The patent application document with the application number CN200910014536.8 discloses a multi-directional tire mold drilling platform, including a support platform, an upper plate, and a support rod. The support rod is provided with a lateral movement shaft, and the support rod is provided with T...

Problems solved by technology

[0004] However, the technical solution disclosed in the prior art has certain defects. First, the tooling used can only realize one direction of pattern block air hole processing, that is, the air hole processing in the rolling direction of the pattern block, and cannot realize the swing of the pattern block, that is, the tire The normal processing of the pores between the pattern blocks; the second is that the processing of the pores between the pattern blocks is mainly realized by the swing angle of the spindle head of the air hole drilling equipment. Due to the limited range of swing angle and no angle scale, the precise control of the swing angle cannot be realized.
