Embodiment Construction
[0039] Specific embodiments of the present invention will be described below with reference to the accompanying drawings.
[0040] refer to figure 1 , figure 2 , image 3 , Figure 4 , Figure 5 , Image 6 with Figure 7 . A quick die change device for pull tabs, including a static die set 100 and a moving die set 200 that can be pressed together up and down, and the moving die set 200 includes:
[0041] Dynamic frame 1;
[0042] Sliding mold core 2, which can be installed on the upper side of the movable mold frame 1 in a front and rear sliding manner;
[0043] An elastic limit mechanism 3, which is installed on the movable mold frame 1, is used to limit the movement of the sliding mold core 2;
[0044] A thimble mechanism 4, which can be mounted on the movable mold frame 1 up and down;
[0045] It can control the thimble mechanism 4 to move up to the sliding mold core 2 to stabilize the sliding mold core 2, or to pass through the sliding mold core 2 to lift the ma...

Disclosed are a quick die change device for zipper pulls and a using method thereof. The quick die change device comprises a stationary die set and a movable die set which can be mutually pressed andcombined in the vertical direction. The movable die set comprises a movable die frame, a sliding die core, an elastic limiting mechanism and an ejector pin mechanism. The ejector pin mechanism can becontrolled to move upwards to be located in the sliding die core, so that the sliding die core is stabilized, and alternatively the ejector pin mechanism can be controlled to move upwards to penetratethrough the sliding die core, thereby jacking materials on the sliding die core. Moreover, the ejector pin mechanism can be controlled to move downwards, so that the limiting of the ejector pin mechanism on the sliding die core is relieved. The limiting of the elastic limiting mechanism on the sliding die core can be relieved by pressing the elastic limiting mechanism downwards. Due to the arrangement of the elastic limiting mechanism, users can limit the sliding die core through the elastic limiting mechanism, and the sliding die core can be stably installed on the moving die frame; and moreover, the limiting can be relieved only by pressing the elastic limiting mechanism once, and the sliding die core is moved. Operation is easy and convenient, and the die change speed is greatly improved compared with existing dies.
Description
technical field [0001] The invention relates to the field of molds for making pull tabs, in particular to a quick die change device for pull tabs and a method for using the same. Background technique [0002] The existing mold structure for replacing the pull tab is simple, but it is very troublesome to replace the mold core. It is necessary to disassemble the mold from the die-casting machine, and then disassemble the mold and the mold core. Problems such as long mold change time, complicated steps, and high labor intensity are not in line with the rapid development of modern industry. Contents of the invention [0003] The invention provides a quick mold changing device for pull tabs and its use method, the main purpose of which is to overcome the defects of long mold changing time, complicated steps and high labor intensity of existing molds. [0004] In order to solve the problems of the technologies described above, the present invention adopts the following technica...
