Description

Rotary movable type blocks and tire molds

technical field

The invention relates to the field of tire molds, in particular to rotary type blocks and tire molds.

Background technique

At present, the text information on the movable type blocks of the tire mold is fixed and cannot be replaced and adjusted. If adjustment is required, the movable type blocks must be replaced as a whole, which increases the production costs of tire vulcanization and mold manufacturing, and reduces production efficiency.

In particular, the replacement of the year and week number movable type blocks on tire molds is very frequent. Since some values on the year and week number movable type blocks represent the number of weeks, high frequency replacement will inevitably affect production efficiency and increase production costs. Traditional methods The replacement of movable type blocks is manually taken out, and then re-inserted with new movable type blocks. Since the movable type blocks are embedded in the groove of the side plate through interference fit, it is inevitable that the mold will be damaged by shoveling during the replacement process. The appearance quality of the tire will also have adverse effects. Secondly, the edges of the re-inserted movable type blocks generally do not conform to the cavity curve, so that the vulcanized tire will have defects.

In view of the above-mentioned problems in the prior art, the present invention designs and manufactures rotary movable type blocks and tire molds to overcome the above-mentioned defects by combining years of design and use experience in related fields, supplemented by strong professional knowledge.

Detailed ways

In order to facilitate the understanding of those skilled in the art, the present invention will be further described below in conjunction with the accompanying drawings.

Embodiment 1, as shown in Figures 1 to 8, provides a rotary movable type block, which is arranged in the groove of the workpiece (ie, the side plate of the tire mold, hereinafter referred to as the workpiece), and includes a support shaft 2, which preferably can be Move vertically in the workpiece groove. Vertical movement means that the support shaft 2 can move along the depth direction of the workpiece groove. The support shaft 2 is provided with at least one runner 4, which is rotatably arranged on the shaft 2. A runner 4 has multiple rotating surfaces (or side surfaces), each rotating surface is provided with at least year and week number text information, and the purpose of changing the year and week number information is achieved by rotating the runner 4, and the workpiece groove peripheral There is a positioning mechanism, and the positioning mechanism is at least used for positioning the rotating wheel 4. The method of setting text information on the rotating surface can be engraved with an engraving tool or laser engraved, and is not specifically limited.

For the convenience of actual installation, the present invention also includes a box body 1. The box body 1 is arranged in the groove of the workpiece. Positioning grooves are preferably arranged on both sides of the box body 1. The ends of the support shaft 2 are embedded in the positioning grooves to slide and cooperate with the positioning grooves. (The support shaft 2 can slide up and down in the positioning groove). The end of the support shaft 2 can be square or other shapes to ensure that the support shaft 2 will not follow the rotation of the runner 4 when the runner 4 rotates. After the rotary movable type block is made in advance Being installed in the groove of the workpiece can not only ensure the quality of the workpiece, but also improve the installation efficiency.

The positioning mechanism is preferably an outer cover 10 (casing outer cover). The outer cover 10 is detachably installed on the box body 1. The outer cover 10 is provided with a through groove for the embedding of the rotating surface of the runner 4. At the same time, in order to distinguish each rotating surface , we define the rotating surface embedded in the 10-pass groove of the outer cover as the working surface. At the same time, in order to facilitate the rotation adjustment of the runner 4, the two ends of the support shaft 2 of the present invention are connected with the bottom of the box body 1 through elastic components, and the two ends of the elastic component are respectively abutted against the support shaft 2 and the bottom of the box body, and the elastic components make the runner 2 has a tendency to break away from the groove of the workpiece, and the elastic member can be a spring 7, which forces the runner 4 to lean against the outer cover 10 to prevent the runner 4 from rotating, and can avoid the phenomenon of overflowing glue during the vulcanization process. Further, the height position of the runner 4 and the support shaft 2 can be adjusted by an adjusting device, and the adjusting device can be an adjusting screw 3 . The above-mentioned positioning mechanism and adjustment device ensure a smooth transition between a part of the outer peripheral surface of the movable type block and the cavity surface of the mold in actual use, and when it is necessary to rotate and adjust the runner 4, use the adjustment device to compress the spring 7 so that the runner 4 is temporarily separated from the outer cover 10. At this time, the rotation of the runner 4 is not restricted by the outer cover 10. A lever that can extend into the through groove of the outer cover 10 is used to move the runner 4, so that the runner 4 can be rotated and adjusted in the box body 1.

Specifically, springs 7 are provided on both sides of the box body 1, positioning shafts or positioning holes are provided on both sides of the bottom of the box body 1 and both ends of the support shaft 2, and the two ends of the spring 7 are respectively embedded in the positioning shafts or in the positioning holes to align with the box body. The body 1 and the support shaft 2 are in contact with each other; or the two ends of the support shaft 2 are slidably connected with a slide bar, the spring 7 is sleeved on the slide bar, and the two ends of the spring 7 are respectively in contact with the support shaft and the bottom of the box body 1, and the slide One end of the rod is provided with a limiting nut. The upper side of both ends of the support shaft 2 (the side opposite to the spring 7) is fixed with a threaded pipe or a threaded hole, and the adjustment screw 3 is threaded through the outer cover 10 to connect with the support shaft 2, and the support shaft can be adjusted by adjusting the adjustment screw 3 2 and the position (height) of the runner 4 in the box body 1, thereby further detaching the runner 4 from the positioning of the outer cover 10, so as to facilitate the rotation adjustment of the runner 4.

Preferably, a spacer is provided between the two runners 4 of the present invention to avoid rotation interference of the runners 4 .

Preferably, in order to adapt to the movable type block of the year and week number, the runner 4 of the present invention is set as a regular decagon, and each rotating surface is respectively provided with 0-9 numbers or/and other text information. Of course, the present invention can also select other The prismatic runner 4, such as a hexagonal prism, is provided with different text information on each rotating surface according to different requirements. The linear distance between any two edges of the runner 4 is smaller than the distance between the two sides (front and back) of the box body 1, so that the runner 4 can be rotated in the box body 1 .

A specific operation method of a typical embodiment of the present invention.

When it is necessary to adjust the text information of the movable type block, use the adjustment screw 3 to adjust the support shaft 2 and the runner 4 to the inside of the box 1, and the runner 4 is separated from the outer cover 10 for positioning. At this time, turn the runner 4 to the specified rotation The surface is adjusted by the adjusting screw 3, so that the support shaft 2, under the action of the spring 7, represses the rotating surface of the runner 4 to protrude from the outer cover 10, and the working surface of the runner 4 transitions smoothly with the mold cavity surface.
