Detailed Description

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

As shown in fig. 1 to 4, a tire mold separation preventing structure includes a slider 1 and a block 2, and the block 2 is disposed inside the slider 1. The mounting hole of vertical direction is equipped with to slider 1 upper end, is equipped with stop pin 3 in the mounting hole, and 2 back tops of decorative pattern piece that correspond with the mounting hole position are equipped with

spacing hole

6, and 6 diameters in spacing hole are greater than 3 lower extreme diameters of stop pin, and the diameter difference is no longer than 3mm, and 3 lower extremes of stop pin stretch into spacing hole 6 to this prevents that the decorative pattern piece 2 is not hard up on slider 1 even deviate from.

The utility model discloses be equipped with radial through-hole in stop pin 3 upper end, insert in the radial through-hole and be equipped with and hinder back round pin 4.

Preferably, be connected with down-pressing piece on the stop pin 3, down-pressing piece makes stop pin 3 have the trend of moving to spacing hole 6 direction, avoids the lower extreme of stop pin 3 to break away from out from spacing hole 6.

The utility model discloses the mounting hole is established to the shoulder hole, and the shoulder hole hinders back round pin 4 and is arranged in first hole portion 10 including keeping away from the first hole portion 10 of decorative pattern piece 2 and the second hole portion that is close to decorative pattern piece 2, and the diameter of second hole portion is less than the length of hindering back round pin 4. The first bore portion 10 is preferably an oblong hole having a maximum dimension greater than the length of the anti-recoil pin 4 and a minimum dimension less than the length of the anti-recoil pin 4. The second hole portion specifically comprises a middle hole 9 and a lower pressing hole 8, the diameter of the middle hole 9 is smaller than that of the lower pressing hole 8, a boss 7 is arranged at the lower end of the stop pin 3, the boss 7 extends into the limiting hole 6, the lower pressing piece is set to be a spring 5, the spring 5 is located in the lower pressing hole 8, the spring 5 is sleeved on the stop pin 3, and two ends of the spring 5 abut against the step and the boss 7 of the second hole portion respectively, so that the stop pin 3 is guaranteed to move towards the direction of the limiting hole 6.

After the block pin 4 moves out of the first hole part 10, the lower end of the stop pin 3 is separated from the limiting hole 6, the block pin 4 can be rotated by a certain angle to be overlapped with the narrow direction of the long round hole, and the block pin 4 is directly erected above the long round hole.

It is further right below that the utility model discloses an installation and dismantlement process introduces:

during assembly, the anti-return pin 4 is placed in the long round hole in the upper end face of the sliding block 1, the lower end of the stop pin 3 can be inserted into the limiting hole 6 in the pattern block 2, the boss 7 at the lower end of the stop pin 3 is kept in the limiting hole 6 under the action of elastic force of the spring 5, the stop pin 3 cannot be separated, and the anti-falling effect of the pattern block 2 is achieved.

When the anti-return pin is detached, the lower end of the stop pin 3 is separated from the limiting hole 6 by pulling the anti-return pin 4 upwards, at the moment, the pattern block 2 can be normally detached, and because the minimum size of the long round hole is smaller than the length of the anti-return pin 4, the anti-return pin 4 can be pulled upwards and rotated to facilitate detachment, the position relation between the anti-return pin 4 and the long round hole in the upper portion of the mounting hole is changed, the anti-return pin 4 is located on the upper end face of the sliding block 1, and then the pattern block 2 is detached.

Because of the block 2 upper and lower ends generally do not exceed 1mm with the total clearance of slider 1, so stop pin 3 insert in block 2 mounting hole more than 2mm can, even 2 connecting screw of block deviate from, block 2 can not deviate from under 3 effect of stop pin yet, reach anti-drop effect.

In this embodiment and the accompanying drawings, the anti-disengaging structure is specifically installed on the upper portion of the slider 1, and those skilled in the art can also install the anti-disengaging structure on the bottom of the slider 1, and such equivalent forms also belong to the protection scope of the present invention.

It should be understood that these examples are for illustrative purposes only and are not intended to limit the scope of the present invention. Furthermore, it should be understood that various changes, modifications and/or alterations to the present invention may be made by those skilled in the art after reading the technical disclosure of the present invention, and all such equivalents may fall within the scope of the present invention as defined by the appended claims.
