Detailed Description

The scheme of the application is further described with reference to the accompanying drawings:

Referring to fig. 1-3, an automatic demolding assembly comprises an ejection module 1, a fixed block 2, a sliding block 3, a mold core 4, an upper mold plate 5 and a lower mold plate 6.

The ejection module 1 comprises two blocks which are respectively arranged at two ends of the fixed block 2, and the middle part of the ejection module 1 is fixedly connected with the end part of the fixed block 2.

The ejector module 1 is provided with a guide rail 7, the number of the sliding blocks 3 is two, the sliding blocks are respectively arranged on two sides of the fixed block 2 and are parallel to the fixed block 2, and two ends of the sliding blocks 3 are arranged on the guide rail 7. Specifically, the two ends of the sliding block 3 are provided with notches 31, guide blocks 32 are arranged in the notches 31, the guide blocks 32 are provided with guide grooves corresponding to the guide rails 7, and the sliding block 3 slides through the cooperation of the guide grooves and the guide rails 7. Further, two air cylinders 8 are arranged on the guide rail 7 on each ejection module 1, the telescopic ends (one end with a telescopic rod) of the air cylinders 8 are connected with the end parts of the sliding blocks 3, and the sliding blocks 3 on two sides are driven to slide close to or far away from the fixed blocks 2 through the telescopic operation of the air cylinders 8. The air inlet pipe 81 of the air cylinder 8 is arranged along the side wall of the ejection module 1.

The mold core 4 is formed by splicing a first core block 41 and a second core block 42, the first core block 41 is fixedly arranged on the fixed block 2, the second core block 42 is fixedly arranged on the sliding block 3, and the second core block 42 faces the first core block 41. The first core 41 is provided with a groove 411, and the second core 42 is provided with a boss 421 corresponding to the groove 411.
