[0002] Internal mold release agents are polymer molding processing aids added inside the polymer material system. They reduce the adhesion of molded products to the mold cavity wall, facilitate demolding, and improve the product rejection rate and labor production efficiency. Compared with external mold release agents that are sprayed separately on the mold cavity wall before injection molding, different liquid raw materials need to be added during the production of internal addition release agents, and the amount added needs to be added according to the ratio.

[0028] It should be noted that, since the existing release agent liquid feeding components are prone to insufficient feeding accuracy, some viscous liquids in the release agent production process will be adsorbed on the inner wall of the discharge pipe. With each feeding, the adsorption amount on the inner wall of the discharge pipe will change, resulting in uncontrollable liquid feeding amount each time. In this embodiment, the piston 73 pushes the liquid adsorbed on the inner wall of the quantitative feeding barrel 6 downward, so that all the liquid flows out of the quantitative feeding barrel 6, avoiding the problem of insufficient outflow caused by the adsorption of some high-viscosity liquid on the inner wall of the quantitative feeding barrel 6, ensuring the accuracy of the liquid feeding amount, and spraying the pressurized liquid through the spray hole 14, so that the liquid is sprayed downward evenly, thereby improving the mixing efficiency of multiple liquids.

[0029] Specifically, in this embodiment, this scheme mainly includes a liquid feeding component 7 and a quantitative adjustment component 8. During the production process of the release agent, liquids of different components are poured into three liquid storage cylinders 4 through a liquid feed port 12. According to the amount of liquid required to be added each time, the position of the limit block 82 is adjusted, and the screw 81 is rotated. The limit block 82 at the bottom of the screw 81 rises and falls in the quantitative feeding cylinder 6. The height of the limit block 82 is accurately controlled according to the scale line on the outer wall of the quantitative feeding cylinder 6. When the liquid is added, the first electric push rod 71 drives the piston 73 to move upward inside the quantitative feeding cylinder 6 through its output end, and a negative pressure environment is formed inside the quantitative feeding cylinder 6. The liquid storage cylinder 4 is filled with liquid. The liquid passes through the connecting pipe 5 and the one-way valve 74 on the piston 73 and enters the inner bottom of the quantitative feeding cylinder 6. When the pressure sensor on the piston 73 contacts the limit block 82, the first electric push rod 71 drives the piston 73 to reset through its output end, and the second electric push rod 76 drives the valve plate 77 to move through its output end. The valve plate 77 pulls out the quantitative feeding cylinder 6, and the liquid flows downward. As the piston 73 moves downward, the piston 73 pushes the liquid adsorbed on the inner wall of the quantitative feeding cylinder 6 downward, so that all the liquid flows out of the quantitative feeding cylinder 6, ensuring the accuracy of the liquid feeding amount. The liquid is sprayed out through the spray hole 14 at the bottom of the spray hood 13 under extrusion, and the liquid is sprayed downward evenly.

[0030] The present utility model embodiment provides a liquid feeding component for producing a release agent with a spraying structure, such as Figure 1 and Figure 5 As shown, it includes a base 1, the top of the base 1 is slidably connected to a swivel 91 in a sleeve position adjustment assembly 9, and the top of the base 1 is rotatably connected to a gear 92 near the inner side of the swivel 91, the top of the swivel 91 is fixedly connected to a sleeve 93 by bolts, the top of the sleeve 93 is embedded with an infrared transmitter 10, and the bottom of the top plate 3 is embedded with an infrared receiver 11 near the position directly above the infrared transmitter 10.

[0031] Specifically, in this embodiment, this scheme mainly includes a sleeve position adjustment component 9, and a mixing barrel for the production of a release agent is inserted into a sleeve 93. When liquid is added into the sleeve 93, an external stepper motor drives a gear 92 to rotate through its output end, and the swivel 91 is rotated through the meshing connection between the gear 92 and the swivel 91, and the sleeve 93 on the swivel 91 is adjusted in position. When the infrared ray emitted by the infrared transmitter 10 is received by the infrared receiver 11, the sleeve 93 no longer moves in position, so that the sleeve 93 is located directly below the quantitative feeding barrel 6, and the sleeve 93 collects the liquid to achieve subsequent mixing of multiple liquids.

[0032] In a further preferred embodiment of the present invention, Figure 3 As shown, the piston 73 performs piston-like motion inside the quantitative feeding cylinder 6, and scale lines are provided on the outer side wall of the quantitative feeding cylinder 6.

[0033] In this embodiment, it can be ensured that the liquid adsorbed on the inner wall of the quantitative feeding cylinder 6 can be scraped off during the downward movement of the piston 73, thereby avoiding the problem of uncontrollable feeding amount caused by liquid adsorption.

[0034] In a further preferred embodiment of the present invention, Figure 1 As shown, the rotating ring 91 and the gear 92 are connected by gear teeth meshing, and the bottom center position of the gear 92 is connected and fixed to the output end of the external stepping motor.

[0035] In this embodiment, the position of the sleeve 93 can be adjusted by rotating the rotating ring 91 .
