[0034] Working principle:

[0035] As Figures 1 to 6As shown, before use, the user needs to determine the position of the circular material returning block 33 and the square material returning block 35 according to the shape of the product inside the mold, if the size of the product is small, the user does not need to rotate the mounting plate 31, when the size of the product is large, the user needs to rotate the positioning block 32 counterclockwise, the positioning block 32 drives the integral positioning column close to one end of the driving column 2 to rotate counterclockwise, since the integral positioning column close to one end of the driving column 2 of the positioning block 32 is screwed to the end of the driving column 2 away from the electric push rod body 1, therefore, when the integral positioning column close to one end of the driving column 2 of the positioning block 32 rotates counterclockwise, it gradually moves away from the driving column 2 relying on the screw, the integral positioning column close to one end of the driving column 2 of the positioning block 32 drives the positioning block 32 away from the driving column 2 when moving away from the driving column 2, the positioning block 32 drives the blocking strip 310 away from the mounting plate 31 when moving away from the driving column 2, thereby releasing the limiting of the mounting plate 31, then the user manually flips the mounting plate 31 by 180 degrees, thereby completing the position replacement of the circular material returning block 33 and the square material returning block 35, and further enabling the device to perform material returning treatment on products of different sizes, thereby meeting the material returning needs of products of different shapes and sizes, after switching, rotate the positioning block 32 clockwise, and restore the positioning block 32 and the integral positioning column close to one end of the driving column 2 of the positioning block 32 to the state shown in the figure Figure 3 ;

[0036] By installing the plug block 37 on the outer surface of the circular material returning block 33 and the square material returning block 35 respectively, and the plug block 37 is inserted in the slot on the mounting plate 31, when pulling the square material returning block 35 upward, the square material returning block 35 drives the plug block 37 to move upward when moving upward, the plug block 37 drives the clamping block 39 to move upward when moving upward, the clamping block 39 is extruded into the receiving groove on the plug block 37 by the inner wall of the slot when moving upward, the clamping block 39 is pressed against the elastic column 38 after entering the receiving groove, so that the elastic column 38 is deformed, when the plug block 37 and the clamping block 39 are moved out of the slot, the clamping block 39 is popped out by the elastic force of the elastic column 38 at this time, on the contrary, when the plug block 37 is inserted into the slot on the mounting plate 31, the clamping block 39 is popped out into the clamping groove on the plug block 37 by the elastic force of the elastic column 38, thereby positioning the plug block 37, and further, the square material returning block 35 and the circular material returning block 33 are installed on the outer surface of the mounting plate 31 in a quick disassembly and installation mode such as plug-in and clamping, thereby installing the utility model in different directions of the mold, and further maximizing the thrust of the material returning device, reducing the probability of damage to the product when exiting the mold, thereby improving the material returning effect on the product

[0037] When the user aligns the circular ejection block 33 or the square ejection block 35 to the outer surface of the product, turns on the power supply of the electric push rod body 1, the piston rod inside the electric push rod body 1 drives the driving column 2 to move away from the electric push rod body 1, the driving column 2 drives the multiple processing mechanisms to move away from the electric push rod body 1 when moving away from the electric push rod body 1, thereby ejecting the product from the mold, through the installation of the brush 1 34 and the brush 2 36 on the outer surface of the square ejection block 35 and the circular ejection block 33, thereby completing the cleaning of the mold during the ejection process, thereby reducing the cleaning process of the mold after the ejection, thereby keeping the mold clean after the ejection, and through the staggered distribution of the brush 1 34 and the brush 2 36, thereby making up for the gap between the bristles on the brush, thereby more comprehensively cleaning the mold, thereby improving the cleaning effect of the inner wall of the mold.
