Description

Technical Field

[0001] This application relates to the field of lipstick production molds, and more particularly to a filling mold for sandwich lipsticks. Background Technology

[0002] Lipstick is a popular cosmetic product. To enhance the consumer experience, manufacturers have introduced sandwich lipsticks.

[0003] A sandwich lipstick consists of an outer lipstick and an inner lipstick. The outer lipstick has a hollow structure with a through hole in the middle. The inner lipstick is filled into the through hole in the middle of the outer lipstick. After solidification, it forms a whole lipstick structure. When consumers apply lipstick, the outer lipstick and the inner lipstick are applied to the lips at the same time, which makes the beautification effect of the lip color better and makes it easier for manufacturers to design lip gloss colors with high process requirements.

[0004] The aforementioned technical solutions have the following drawbacks: In the production process of sandwich lipsticks, it is necessary to first fill and produce an outer lipstick with a central through hole, and then fill the inner lipstick into the central through hole of the outer lipstick. The process is cumbersome and results in low production efficiency. Utility Model Content

[0005] In order to improve the production efficiency of sandwich lipsticks, this application provides a filling mold for sandwich lipsticks.

[0006] The technical solution for a sandwich lipstick filling mold provided in this application is as follows:

[0007] A sandwich lipstick filling mold includes multiple templates, each template including a bottom mold, a middle mold, and a top mold. The bottom mold includes an end plate and multiple irregular rods. The end plate is a flat plate structure. One end of each irregular rod is fixed to the end plate. The irregular rods are perpendicular to the end plate and are arranged at equal intervals along the length of the end plate. The middle mold has multiple through holes, and the top mold has multiple receiving holes. The irregular rods are used to insert into the through holes and receiving holes.

[0008] By adopting the above technical solution, the bottom mold, middle mold, and top mold are connected and abutted against each other, allowing the shaped rod to be inserted into the through hole and receiving hole. The user injects liquid lipstick material into one side of the top mold, and after the liquid material solidifies, it can form a hollow lipstick in the middle mold and top mold. At this time, the user pulls out the bottom mold, allowing the shaped rod to be pulled out from the hollow lipstick. The user can then inject liquid lipstick material of other colors into the outer lipstick, thereby improving the efficiency of producing sandwich lipsticks.

[0009] Optionally, a second bottom mold can be detachably connected to the middle mold, which is used to seal the opening on one side of the through hole.

[0010] By adopting the above technical solution, by setting a bottom mold second on the middle mold, the bottom mold second can cover the side surface of the middle mold away from the top mold, so that the bottom mold second can block the end of the through hole, thereby reducing the probability of leakage when other colors of lipstick raw materials are poured into the external lipstick.

[0011] Optionally, a stripping template is slidably connected to the irregularly shaped rod, and the stripping template has multiple insertion holes, into which the irregularly shaped rod is inserted.

[0012] By adopting the above technical solution, and by setting a release template on the irregular rod, when the middle mold and top mold are installed, the release template abuts against the end plate, one side of the middle mold abuts against the release template, and the other side abuts against the top mold. When the external lipstick solidifies in the middle mold and top mold, the user slides the end plate relative to the release template, and the release template remains stationary relative to the middle mold. At this time, the release template can hold the external lipstick in the through hole, reducing the probability that the lipstick will come out of the middle mold along with the irregular rod when the bottom mold is pulled out.

[0013] Optionally, the bottom mold has multiple grooves, including an outer circular groove and an irregular groove. The cross-section of the irregular groove is the same as the cross-section of the irregular rod, and the diameter of the outer circular groove is the same as the diameter of the through hole.

[0014] By adopting the above technical solution, by opening grooves on the bottom mold two, when the bottom mold two is connected to the middle mold, the grooves correspond one-to-one with the through holes. At this time, the inner lipstick material is poured into the outer lipstick, which can make the end faces of the inner and outer lipsticks relatively flat, reduce the chance of the inner lipstick leaking, and make the production quality of sandwich lipsticks higher.

[0015] Optionally, a recessed groove is provided on the top mold, which is located on the side of the top mold away from the middle mold, and the recessed groove is connected to the end of the receiving hole.

[0016] By adopting the above technical solution, a sinking groove is opened on the top mold, which is connected to multiple receiving holes in the top mold. The user can place the top mold horizontally and make the sinking groove face vertically. At this time, liquid lipstick raw material is injected into the sinking groove, so that the liquid lipstick raw material can flow evenly into multiple receiving holes, making the lipstick length in each receiving hole similar, thus improving the production quality.

[0017] Optionally, multiple positioning blocks are provided on the end face of the template that abuts against the adjacent template, and multiple slots are opened on the surface of the template, with the positioning blocks used to be inserted into the slots.

[0018] By adopting the above technical solution, positioning blocks are set on the template so that the position of the positioning blocks corresponds to the slots on other templates. When two adjacent templates abut against each other, the positioning blocks can be inserted into the slots, thereby improving the connection stability of the two adjacent templates, reducing the probability of relative lateral movement of adjacent templates, and reducing the probability of lipstick breaking or deforming in the through hole and receiving hole.

[0019] Optionally, the template is magnetically connected to the adjacent template.

[0020] By adopting the above technical solution, magnets are set on the templates so that adjacent templates can be magnetically connected to each other, thereby improving the connection tightness between the templates and reducing the chance of liquid lipstick raw materials leaking from the gaps between adjacent templates.

[0021] Optionally, the template has protrusions on both sides, and when two adjacent templates abut against each other, there is a gap between the protrusions on the two templates.

[0022] By adopting the above technical solution, and by setting protrusions on the template, users can peel off adjacent templates through the protrusions, thereby facilitating the removal of the templates and taking out the solidified sandwich lipstick.

[0023] In summary, the beneficial technical effects of this application are as follows:

[0024] 1. By connecting and abutting the bottom mold, middle mold, and top mold together, the irregular rod is inserted into the through hole and receiving hole. The user injects liquid lipstick material into one side of the top mold. After the liquid material solidifies, it can form a hollow lipstick in the middle mold and top mold. At this time, the user pulls out the bottom mold, which allows the irregular rod to be pulled out from the hollow lipstick. The user can then inject liquid lipstick material of other colors into the outer lipstick, thereby improving the efficiency of producing sandwich lipsticks.

[0025] 2. By setting a bottom mold on the middle mold, the bottom mold can cover the side surface of the middle mold away from the top mold, and the bottom mold can block the end of the through hole, thereby reducing the chance of leakage when other colors of lipstick raw materials are poured into the external lipstick.

[0026] 3. By setting positioning blocks on the template, the positions of the positioning blocks correspond to the slots on other templates. When two adjacent templates abut against each other, the positioning blocks can be inserted into the slots, thereby improving the connection stability of the two adjacent templates, reducing the probability of relative lateral movement between adjacent templates, and reducing the probability of lipstick breaking or deforming in the through hole and receiving hole.

[0035] The present application will be further described in detail below with reference to the accompanying drawings.

[0036] This application discloses a filling mold for sandwich lipsticks, referring to... Figure 1 , Figure 2 and Figure 3 The system comprises multiple templates, including a bottom mold 1, a second bottom mold 2, a middle mold 3, and a top mold 4. The bottom mold 1 includes an end plate 11 and multiple irregularly shaped rods 12, which are vertically fixed to the end plate 11. The multiple irregularly shaped rods 12 are equidistantly spaced along the length of the end plate 11. The middle mold 3 is a plate-like structure with multiple through holes 31 equidistantly spaced on it. Each irregularly shaped rod 12 can be inserted into one through hole 31. The top mold 4 has multiple receiving holes 41, and each irregularly shaped rod 12 is used to be inserted into one receiving hole 41. The through holes 31 and receiving holes 41 are coaxial circular holes. When the bottom mold 1, middle mold 3, and top mold 4 are connected to each other, the user can pour the liquid raw material for making lipstick into the receiving holes 41, allowing the lipstick to solidify and form in the through holes 31 and receiving holes 41. The solidified lipstick has a hollow structure, and the cross-section of the through holes of the lipstick is the cross-sectional shape of the irregularly shaped rod 12. The user pulls the bottom mold 1 out of the middle mold 3, so that the bottom mold 2 is placed on the middle mold 3. At this time, the bottom mold 2 is placed on one end of the lipstick and seals the opening at the end of the lipstick. The user pours lipstick raw materials of other colors or materials into one side of the top mold 4, so that the through hole in the middle of the lipstick is filled with liquid lipstick raw materials. After the lipstick solidifies, it forms a sandwich structure, thus achieving the production purpose.

[0037] Reference Figure 1 and Figure 2A stripping template 13 is slidably connected to the irregularly shaped rod 12. The stripping template 13 is a flat plate structure with multiple insertion holes 131. Each irregularly shaped rod 12 is inserted into one insertion hole 131. The stripping template 13 is installed on the bottom mold 1, and then the middle mold 3 and the top mold 4 are installed on the bottom mold 1. When the bottom mold 1, the middle mold 3, and the top mold 4 are connected to each other, one side of the middle mold 3 abuts against the stripping template 13, and the other side abuts against the top mold 4. After the lipstick solidifies in the through hole 31 and the receiving hole 41, the user needs to pull the bottom mold 1 out of the middle mold 3. The user can make the stripping template 13 abut against the middle mold 3, so that the bottom mold 1 slides relative to the stripping template 13, thereby allowing the solidified lipstick to stay in the through hole 31 and the receiving hole 41, reducing the chance of the lipstick sliding out with the irregularly shaped rod 12.

[0038] Reference Figure 4 The second bottom mold 2 includes a cover plate 21 with multiple grooves 22 spaced along its length. Each groove 22 includes an outer circular groove 221 and a shaped groove 222. The cross-section of the shaped groove 222 is the same as the cross-section of the shaped rod 12, and the diameter of the outer circular groove 221 is the same as the diameter of the through hole 31. When the second bottom mold 2 is connected to the middle mold 3, the second bottom mold 2 covers one side of the middle mold 3, and the positions of the grooves 22 correspond one-to-one with the through holes 31. By creating grooves 22 on the second bottom mold 2, the structure of the filled lipstick is clearly defined, reducing the chance of the middle and outer parts of the lipstick mixing.

[0039] Reference Figure 5 and Figure 6 Each template has a positioning block 5 on the surface that abuts with other templates, and a slot 6 is provided on the surface that abuts with other templates. The positions of the positioning block 5 and the slot 6 correspond one-to-one. When the template abuts with other templates, the positioning block 5 can be inserted into the slot 6, which can make the templates align with each other, thereby reducing the probability of lateral misalignment between adjacent templates and making the lipstick production quality higher.

[0040] Reference Figure 7 The top mold 4 has a recess 42, which is located on the end face of the top mold 4 away from the middle mold 3. The recess 42 is connected to the end of the receiving hole 41. The user can pour liquid lipstick material into the recess 42, so that the lipstick material flows into the receiving hole 41 and solidifies in the receiving hole 41, thereby making the difference in lipstick length in each receiving hole 41 smaller.

[0041] Reference Figure 1 Adjacent templates are magnetically connected to each other. By placing magnets on the templates, adjacent templates are magnetically connected when they come into contact, further improving the tightness of the connection between the templates and reducing the chance of lipstick material leaking out from the gaps between adjacent templates.

[0042] Reference Figure 2The template has protrusions 7 on both sides in the width direction. When adjacent templates abut each other, there is a gap between the protrusions 7 on the two templates. Users can pry open the two templates that are magnetically attracted to each other through the protrusions 7, thereby improving the efficiency of disassembling the templates.

[0043] The implementation principle of this application embodiment is as follows: by connecting the bottom mold 1 with the middle mold 3 and the top mold 4, the irregular rod 12 is inserted into the through hole 31 and the receiving hole 41, so that the lipstick can solidify to form a hollow structure. At this time, the user can pour lipstick raw materials of different colors into the through hole in the middle of the lipstick, so that the lipstick solidifies to form a sandwich structure.

[0044] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
