Clamping device capable of being used for conveniently clamping tire mold slide block

Abstract

The invention provides a clamping device capable of being used for conveniently clamping a tire mold slide block. The clamping device comprises a support block capable of being used for carrying the tire mold slide block, wherein the top surface of the support block is an inclined surface; when the tire mold slide block is put on the inclined surface of the support block, the top surface of the tire mold slide block is a horizontal surface; the front side of the support block is provided with a positioning block; the tire mold slide block is abutted against the positioning block; the back side of the support block is provided with a tail clamping unit; the tire mold slide block can be clamped in the forward and backward direction when the tail clamping unit is moved; stop blocks capable of doing reciprocating moving in the left and right directions are arranged at the left and right opposite sides of the support block; the stop blocks arranged on the two opposite sides are connected through a lead screw; when the lead screw rotates, the stop blocks simultaneously approach to the center of the tire mold slide block in the left and right directions or simultaneously and outwards move, so that the slide block center is kept unchanged; the automatic centering is realized. The clamping device can realize the multi-directional positioning, and can be changed according to the tire mold slide blocks in different dimensions, and the universality is realized.

Description

technical field [0001] The invention belongs to the field of tire building machinery, and in particular relates to a clamping device used for processing slideways on tire mold sliders. Background technique [0002] Tires are manufactured by injection molding in tire molds, and multiple tire mold sliders form a full circle, which is a unit group in tire processing. The tire mold slider moves from bottom to top along the upper slideway of the tire mold slider to form a complete closed tire mold to realize processing. After the processing is completed, the tire mold slider moves down along the slideway, and the tire mold is separated. , the injection molded tire is released from the mold. The tire mold slider obtains the ring-shaped whole of the slideway by integral injection molding, and divides it into equal parts (generally 9 equal parts) after cutting. [0003] see figure 1 , is the structural diagram of the tire mold slider, such as figure 1 As shown, the arc diameters...

AI Technical Summary

Problems solved by technology

[0006] (1) The top surface of the clamping device is a curved surface, which is cumbersome to process, takes a long time to process and requires high precision;

[0007] (2) The size of the clamping device is single after processing, which can only meet the clamping of the same type of tire mold sliders, and the size of the clamping devices required by different tire mold sliders is different, resulting in a very large number of clamping devices. At the same time, due to the large amount of inventory, storing these fixtures also takes up a lot of space;

[0008] (3) Each fixture can only clamp and produce one kind of tire mold slider, and the utilization rate is low;

[0009] (4) Due to the rapid replacement of tire molds, about 50%-80% of the clamping devices need to be updated every 3-4 years, and a large number of special clamps are eliminated in the product replacement, resulting in great waste
