detailed description

The utility model will be described below in conjunction with specific embodiments.

As shown in Figure 1-2, a mold secondary ejection structure includes an upper template 1 and a corresponding matching lower template 2. A mold cavity 3 is provided inside the upper template 1 and the lower template 2, and the upper end of the upper template 1 is installed. There is a panel 11, a base plate 21 is installed at the lower end of the lower formwork 2, and a square iron 4 is installed between the base plate 21 and the lower formwork 2. The upper end of the square iron 4 is provided with a thimble plate stroke groove 41, and the thimble plate stroke groove 41 is arranged from the bottom. The first ejector plate 42, the second ejector plate 43 and the third ejector plate 44 are installed in sequence on the top, the upper end of the ejector plate one 42 runs through the second ejector plate 43, the third ejector plate 44 and the first ejector pin 5 from the lower template 2 to the bottom of the mold cavity 3, The upper end of the ejector plate two 43 is equipped with an ejector pin two 6 that runs through the ejector plate three 44 and the lower template 2 to the bottom of the mold cavity 3 , and the ejector plate one limit groove 411 is provided on the bottom side wall of the ejector plate travel groove 41 .

Further, a water transport board 12 is installed between the upper template 1 and the panel 11 .

Further, the bottom plate 21 is installed on the lower end of the lower template 2 through the pins 22 that pass through the first thimble plate 42, the second thimble plate 43 and the third thimble plate 44 to the lower template 2, and the upper end of the pin 22 is set on the upper end of the lower template 2. The guide sleeve one 23 on the upper end of the ejector plate one 42 and the guide sleeve two 24 installed on the upper end of the ejector pin plate two 43 and the three ejector plate 44, the pin 22 fixes the base plate 21 and the square iron 4 while aligning the ejector plate one 42 , ejector plate two 43 and ejector plate three 44 play a guiding role.

Further, the upper end of the ejector plate 2 43 is provided with a rubber plug 431 in contact with the ejector plate 1 42 , and the rubber plug 431 has the function of buffering and positioning the ejector plate 1 42 .
