Description

Quick die change device

This creation is about a quick mold changing device, which forms an intersection and penetration between the X-axis accommodating groove, Y-axis accommodating groove and Z-axis hole of the mold base body, and uses the above-mentioned grooves. Plural parts are pushed against each other to locate and lock or release and unlock the quick connector, thereby achieving rapid mold change.

(1) First of all, the conventional mold changing device, as shown in the patent number I676523, includes: a mold base body is provided with more than one X-axis hole, and the front section of the X-axis hole is provided with internal threads. There are two Z-axis holes on the side of the X-axis hole, and the three form the first and second intersection area. More than one central rod is provided with a tool set connection hole and the front section is provided with an external thread. The external thread is screwed to the X-axis hole Internal thread, the central rod body is provided with a first and second tapered surface and a reduced diameter section corresponding to the first and second intersection area, and the peripheral surface of the quick connector is provided with a ring groove, which corresponds to the first and second intersection area. Therefore, adjusting the first and second cone surfaces of the central rod body to enter the ring groove requires immediate positioning of the quick connector, and adjusting the first and second tapered surfaces of the central rod body to retreat from the ring groove immediately unlocks. However, its main disadvantages are as follows: Since the above-mentioned conventional mold changing device has two central rods, when positioning or unlocking the quick connector, the two central rods must be adjusted first and then, which is very difficult for the user to operate. It is troublesome and time-consuming.

(2) Secondly, another conventional mold changing device, as shown in the patent certificate number M597700, The mold changing device has multiple X-axis guide holes and Y-axis guide holes at the same time. Its main disadvantages are as follows: Because the mold base body is usually a solid structure, the X-axis guide hole is formed by precision machining. , Y-axis guide hole, when the mold changing device is used for a long time, dust and iron filings will accumulate in the X-axis guide hole and Y-axis guide hole, and cause it to be in the X-axis guide hole and Y-axis guide hole The sliding components are stuck and cannot be moved. Therefore, if you want to clean the X-axis guide holes and Y-axis guide holes, or even repair and replace parts, you must remove all the components in the X-axis guide holes and Y-axis guide holes. All are removed, resulting in difficult, troublesome and time-consuming cleaning.

(3) Furthermore, since the push rod and the shaft hole of the conventional mold changing device are relatively formed into a circular structure, therefore, in actual operation, the pusher sometimes rotates slightly in the axial direction, and even The oblique tapered surface of the push rod cannot be reliably tightened due to the angle change, resulting in insufficient push and positioning strength of the overall conventional mold changing device.

(4) Finally, because the general quick mold change device and all its parts cannot reach 100% processing accuracy during processing and forming, there are slight errors, and there will be errors after the corresponding assembly, which makes the quick change In the actual operation of the mold device, when the parts are pushed against each other or released, sometimes the parts are stuck and cannot be moved.

Therefore, how to quickly lock or unlock the quick connector, thereby shortening the mold changing time of the mold changing device, and making it easy to clean, replace parts, or repair the mold changing device, and even increase the strength of component pushing and positioning, and solve the problem of parts jamming The irreducible situation is actually the goal of the research and development efforts of the relevant industry.

In view of the fact that the conventional mold changing device must be adjusted first and then the multiple central rods, so as to Positioning or unlocking the quick connector, and it is not easy to clean, replace parts, or repair the mold changing device, and there are problems that the parts are stuck and cannot be pushed.
