detailed description

For the embodiment, please refer to Fig. 1-Fig. 7, a quick disassembly fastening device for mold assembly of the present invention, including a first channel located in one of the molds 5 and a second channel located in the other mold 6 The channel, as well as the fastening rod 1 and the elastic member, the fastening rod 1 is made of stainless steel, and a positioning part is provided on it, and a matching part is provided in the second channel. When installing, the fastening rod 1 passes through the first channel and enters the second channel. Two channels, and the positioning part is driven into or out of the matching part of the second channel by the rotation of the fastening rod 1 at a preset angle; the elastic member stretches between the fastening rod 1 and the inner wall of the first channel or one of the molds 5 .

In this embodiment, it also includes a first set 3 attached to one of the molds 5, the inner cavity of the first set 3 constitutes the first channel; it also includes a second set 4 attached to another mold 6, The inner cavity of the second sleeve 4 constitutes the second channel. Specifically, the first set 3 is embedded in one of the molds 5 , and the second set 4 is embedded in the other mold 6 .

In this embodiment, the elastic member is a spring 2, which is sleeved on the fastening rod 1, and the fastening rod 1 has a first limit portion, and the inner wall of the first passage is provided with a second limit part, and the two ends of the spring 2 respectively abut against the first limiting part and the second limiting part. The first limiting part is a nut 7 which is screw-fitted on the fastening rod 1 . The second limiting portion is a boss 31 provided on the inner wall of the first channel (ie, the inner wall of the second sleeve 3 ). Specifically, as shown in Fig. 4 and Fig. 5, the outer peripheral contour of the boss 31 is circular, and the inner peripheral contour of the boss 31 is similar to an ellipse (not limited thereto), which is similar to the peripheral contour of the positioning block 11 described below. Adapted so that the positioning block 11 can pass through.

In this embodiment, the positioning part is a positioning block 11 welded to the inner end of the fastening rod 1 and has a non-circular contour around it (before welding the positioning block 11, first install the nut 7 and the spring 2 into the fastening Rod 1), the matching portion is a card platform 41 with a clamping surface facing the inside of the second channel, the inner peripheral contour of the card platform 41 is adapted to the peripheral contour of the positioning block 11, specifically, as shown in Figure 6 and Figure 7 As shown, the inner peripheral contour of the card table 41 is similar to an ellipse (not limited thereto), and the outer peripheral contour of the card table 41 is circular. The surrounding outline of the positioning block 11 is similar to an ellipse, as shown in FIG. 3 . The second sleeve 4 can be specifically divided into a first section body and a second section body along its axial direction. The inner diameter of the first section body is relatively small, and the inner peripheral contour of the first section body is similar to an ellipse. The inner diameter of the second body is larger, and the inner peripheral contour of the second segment is circular, and the junction of the first segment and the second segment forms the card platform 41 . During installation, the inner peripheral contour of the boss of the first set 3 and the inner peripheral contour of the card platform of the second set 4 are arranged in direct alignment, so that the fastening rod 1 can enter the second set 4 smoothly after passing through the first set 3 .
