DETAILED DESCRIPTION

[0022] In the following description, a large number of specific details are given in order to provide a more thorough understanding of the utility model. However, it is obvious for those skilled in the art that the utility model can be implemented without one or more of these details. In other examples, in order to avoid confusion with the utility model, some technical features known in the art are not described.

[0023] Therefore, the applicant designed as follows Figures 1-4 One of the examples shown is as follows Figure 1 As shown, the quick-installation structure of the injection molding machine brake linkage pin 4 in this embodiment includes: an upper linkage 2 seat 1, which includes a first upper linkage 2 seat 1 and a second upper linkage 2 seat 1, which are connected and fixed by a linkage pin 4; an upper linkage 2, one end of which is fixed to the linkage pin 4, and the upper linkage 2 can rotate on the upper linkage 2 pin; and a lower linkage 12 seat 119, which includes a first lower linkage 12 seat 119. The first lower connecting rod 12 seat 119 and the second lower connecting rod 12 seat 119 are connected and fixed by a connecting rod pin 4; the lower connecting rod 12 has one end of the upper connecting rod 2 fixed on the connecting rod pin 4, and the upper connecting rod 2 can rotate on the lower connecting rod 12 pin 4; the connecting rod connecting seat 7 has two ends connected to the upper connecting rod 2 and the lower connecting rod 12 respectively, and is connected and rotated by the connecting rod pin 4 so that the upper connecting rod 2 and the lower connecting rod 12 can rotate about the connecting rod pin 4 as the axis.

[0024] In this embodiment, the quick-installation structure of the injection molding machine brake linkage pin 4 can be further optionally configured such that the upper linkage pin 2 is fixed to the upper linkage 2 seat 1 and the lower linkage 12 seat 119 by screws 6, and a spring washer 5 for anti-slip is provided between the screw 6 and the upper linkage 2 seat 1 and the lower linkage 12 seat 119. The upper linkage pin 2 is fixed to the upper linkage 2 seat 1, the lower linkage 12 seat 119, and the linkage connecting seat 7 by screws 6, and a spring washer 5 for anti-slip is provided between the screw 6 and the upper linkage 2 seat 1 and the lower linkage 12 seat 119. This design effectively prevents the screw 6 from loosening, ensures the reliability of the connection, reduces maintenance and failure rate, and extends the service life of the equipment.

[0025] In this embodiment, the quick-installation structure of the injection molding machine brake linkage pin 4 can be further optionally configured such that a positioning groove is machined at the midpoint of the alignment between the linkage pin 4 and the upper linkage seat 1 and the lower linkage seat 12 119. A threaded hole is machined at the midpoint of the upper linkage seat 1 and the lower linkage seat 12 119, directly opposite the positioning groove. The threaded hole passes through the upper linkage seat 1 and the lower linkage seat 12 119 and contacts the linkage pin 4. During installation, the end of the positioning pin with the positioning groove is first paired with the linkage seat with the threaded hole. The screw 6 is pre-screwed into the connecting seat, ensuring that the set screw 6 does not contact the linkage pin 4. After the entire linkage mechanism is connected, a wrench is used to tighten the front end of the set screw 6 into the positioning groove of the linkage pin 4 to ensure a secure connection of the linkage pin 4. This quick-installation structure of the linkage pin 4 is simple to operate, requiring only a common Allen wrench. It also reduces the operating space and lowers material and processing costs compared to traditional linkage pin 4 installation structures.

[0026] In this embodiment, the quick-installation structure of the injection molding machine brake linkage pin 4 is further optionally provided with a threaded hole on the linkage connecting seat 7, so that the screw 6 can pass through the threaded hole to fix the linkage pin 4.
