Detailed Implementation

[0034] A lipstick manufacturing process includes the following steps:

[0035] S1: Insert the two inverted conical tips 107 in the preparation device into the two mating mold bodies 104;

[0036] S2: Inject the fluid lipstick into the two mold bodies 104 in the molding device to form the lipstick body 401;

[0037] S3: After the lipstick body 401 is shaped, the two inverted conical tips 107 are pulled out. At this time, V-shaped grooves are formed on both sides of the lipstick body 401.

[0038] S4: Control the two mold bodies 104 to slide away from each other and remove the molded lipstick.

[0039] S3 further includes the following steps:

[0040] S31: Inject the white fluid lipstick into the two V-shaped grooves;

[0041] S32: After the fluid in the two V-shaped grooves is shaped, it forms two inverted cone-shaped pastes 402 that are integrally formed with the lipstick body 401.

[0042] The color of the fluid lipstick in S31 can also be any color that is different from the main color of the lipstick body 401, so as to facilitate observation and differentiation of the inverted cone-shaped paste 402.

[0043] The outer end face of the inverted conical tip 107 is an arc-shaped surface that fits against the inner wall of the mold body 104. This prevents the fluid lipstick from entering the space between the mold body 104 and the inverted conical tip 107 when the fluid lipstick is injected, thus preventing the inverted conical paste 402 that cannot be processed from being exposed on the outside of the lipstick body 401.

[0044] After the lipstick is formed in step S4, its top surface is cut into a bevel for easy use.

[0045] The aforementioned preparation device can also process a hollow lipstick body 401, and inject lipstick into the core of the lipstick body 401, thereby giving the lipstick a moisturizing effect.

[0046] like Figures 4 to 7 As shown:

[0047] The preparation device includes a frame 101, a guide rod 102 fixedly connected to the frame 101, two mold bodies 104 symmetrically slidably connected to the guide rod 102, a bidirectional threaded rod 103 rotatably connected to the frame 101, the two mold bodies 104 being threadedly connected to the two ends of the bidirectional threaded rod 103 respectively, a motor I capable of driving the bidirectional threaded rod 103 to rotate fixedly connected to the frame 101, a vertical frame 108 fixedly connected to the frame 101, a top frame 106 slidably connected to the vertical frame 108, two smooth inverted conical tips 107 symmetrically fixed to the top frame 106, a screw 105 threadedly connected to the top frame 106, and a motor II capable of driving the screw 105 to rotate fixedly connected to the vertical frame 108.

[0048] The control motor II starts, driving the screw 105 to rotate. The screw 105 drives the top frame 106 to move downwards. The top frame 106 drives two inverted conical tips 107 to insert downwards into the two mating mold bodies 104, injecting fluid lipstick into the two mold bodies 104. After the fluid lipstick sets, it forms the lipstick body 401. The control motor II starts in reverse, driving the two inverted conical tips 107 upwards to be pulled out of the lipstick body 401. At this time, V-shaped grooves are formed on both sides of the lipstick body 401. Then, white or a different color from the lipstick body 401 fluid lipstick is injected into the two V-shaped grooves. After the fluid lipstick in the two V-shaped grooves sets, it forms two inverted conical paste bodies 402 integrally formed with the lipstick body 401. Figure 4As shown, the control motor I starts and drives the bidirectional threaded rod 103 to rotate. The bidirectional threaded rod 103 drives the two mold bodies 104 to slide away from each other, and the molded lipstick is taken out. During the use of the lipstick, the remaining amount of lipstick can be judged by observing the inverted conical paste 402 on both sides of the lipstick that is screwed out of the tube. When the inverted conical paste 402 gradually approaches the tip of the cone, it means that the lipstick is almost used up. Therefore, it is not necessary to screw out all the lipstick to directly observe and judge the remaining amount of lipstick. In addition, the inverted conical paste 402 of the lipstick material can also play a role in moisturizing the lips during the application of lipstick.

[0049] like Figures 8 to 10 As shown:

[0050] The preparation device also includes a frame 201, on which two motors III are symmetrically fixed. Each of the output shafts of the two motors III is connected to a lead screw 202 via a coupling. The two lead screws 202 are threaded to both ends of the top frame 106. A smooth core cylinder 301 is connected to the middle of the frame 201.

[0051] After the two inverted conical tips 107 are inserted into the two mold bodies 104, the two motors III are started to drive the two lead screws 202 to rotate. The two lead screws 202 drive the frame 201 to move downward. The frame 201 drives the core cylinder 301 to move downward and insert into the two mold bodies 104. At this time, the fluid lipstick is injected into the two mold bodies 104. The two mold bodies 104 surround the core cylinder 301, so that the lipstick body 401 formed after shaping is hollow. The motor III is started in reverse to drive the frame 201 and the core cylinder 301 to move upward. After the core cylinder 301 is pulled out from the lipstick body 401, the fluid lipstick is injected into the hollow lipstick body 401. After the fluid lipstick in the core is shaped, a lipstick with a sandwich lipstick in the core is formed, which better moisturizes the lips.

[0052] like Figures 9 to 12 As shown:

[0053] A T-shaped frame 204 is fixedly connected to the frame 201. Two vertical rods 205 located inside the core cylinder 301 are symmetrically slidably connected to the T-shaped frame 204. Multiple protrusions 206 are fixedly connected to both vertical rods 205. Multiple slots 304 are vertically opened on both sides of the core cylinder 301, and the multiple protrusions 206 are respectively inserted into the multiple slots 304.

[0054] When the core tube 301 is located inside the two mold bodies 104, the two vertical rods 205 are controlled to slide away from each other, so that the two vertical rods 205 drive the protrusions 206 on them to pass through the surface of the core tube 301. Then, the liquid lipstick is injected into the two mold bodies 104. The liquid lipstick wraps around the multiple protrusions 206. After the liquid lipstick is shaped, the two vertical rods 205 are controlled to move closer together. The two vertical rods 205 drive the multiple protrusions 206 on them to be stored in the core tube 301. Then, the core tube 301 is pulled out upwards, so that multiple grooves are formed on both sides of the cavity of the core of the formed lipstick body 401. Liquid lipstick is injected into the core of the lipstick body 401. The liquid lipstick fills the multiple grooves. Multiple protrusions are formed on both sides of the lipstick body 401 core and inserted into the lipstick body 401. The multiple protrusions can prevent the glossy lipstick core from falling off the core of the lipstick body 401 in the high temperature of summer due to the different materials of the lipstick and lipstick body.

[0055] like Figure 11 As shown:

[0056] A hinge block 208 is slidably connected to the T-shaped frame 204. Both ends of the hinge block 208 are hinged to hinge arms 207. The two hinge arms 207 are respectively hinged to two vertical rods 205. An electric push rod is fixedly connected to the T-shaped frame 204. The telescopic end of the electric push rod is fixedly connected to the hinge block 208.

[0057] When the electric push rod is activated, it causes the hinge block 208 to move up and down. The hinge block 208 causes the two hinge arms 207 to move. The two hinge arms 207 cause the two vertical rods 205 to move closer to or further away from each other, so that the two vertical rods 205 cause multiple protrusions 206 on them to extend out of the surface of the core cylinder 301 or be stored inside the core cylinder 301.

[0058] like Figures 10 to 11 As shown:

[0059] A grooved wheel 302 is fixedly connected to the core cylinder 301. Two shift forks 203 are symmetrically fixedly connected to the core cylinder 301. Both shift forks 203 are inserted into the grooved wheel 302. A motor IV is fixedly connected to the T-shaped frame 204. A gear 209 is fixedly connected to the output shaft of the motor IV. An arc-shaped rack 303 is fixedly connected to the core cylinder 301. The gear 209 and the arc-shaped rack 303 mesh and drive each other.

[0060] When the motor IV starts, it drives the gear 209 to rotate back and forth. The gear 209 is connected to the arc rack 303 through meshing transmission, which drives the core cylinder 301 to rotate back and forth between the two forks 203. As the core cylinder 301 is slowly pulled upward from the lipstick body 401, the reciprocating core cylinder 301 can smooth the inner wall of the cavity formed in the core of the lipstick body 401.

[0061] Furthermore, when the core cylinder 301 is located within the two mold bodies 104 and multiple protrusions 206 extend from the surface of the core cylinder 301, the injected liquid lipstick is quickly formed. The core cylinder 301 is controlled to rotate back and forth, and the core cylinder 301 drives multiple protrusions 206 to rotate back and forth, which can expand multiple grooves, thereby increasing the size of the grooves. This makes the size of the protrusions on the core lipstick body that is subsequently processed larger, and the contact surface between them and the lipstick body 401 is larger, so that the lipstick body can be more stably embedded in the core of the lipstick body 401.

[0062] like Figure 13 As shown:

[0063] Each of the two inverted conical tips 107 is fixedly connected to a cover plate 305. The two cover plates 305 are joined together to form a feed inlet 306. The core cylinder 301 is inserted between the two cover plates 305.

[0064] After the two inverted conical tips 107 are inserted into the mold body 104, the bottom surface of the core cylinder 301 is controlled to be coplanar with the two cover plates 305. The fluid lipstick is injected through the feed port 306 into the cavity formed by the two cover plates 305, the two inverted conical tips 107, the two mold bodies 104 and the bottom surface of the core cylinder 301, and the lipstick body 401 is processed.

[0065] When the core tube 301 is inserted downward into the two mold bodies 104, but with a certain gap between it and the bottom surface of the mold body 104, the liquid lipstick is injected through the inlet 306 into the cavity formed by the two cover plates 305, the two inverted conical tips 107, the two mold bodies 104, and the core tube 301, which can produce a hollow lipstick body 401, making it easy to inject liquid lipstick into the lipstick body 401; the bottom surface of the core tube 301 and the bottom surface of the mold body 104 have a certain space, so that the lipstick body 401 can provide a certain support for the lipstick body in the core.

[0066] A lipstick prepared by a lipstick manufacturing process, wherein the lipstick body 401 has inverted cone-shaped paste 402 on both sides for visual observation of the remaining amount of lipstick.
