Description

Technical Field

[0001] The utility model relates to the technical field of cosmetic packaging and molding, in particular to a pre-molding mold. Background Art

[0002] The production process for highlighter products requires placing highlighter powder in a specific aluminum pan and compacting it into a cake using a powder compactor. However, powder products have a relatively loose structure, so the powder in the pan must be compacted to a certain degree before compaction to reduce air in the powder. This ensures precise control of the powder volume and ensures that the powder processing standards are met.

[0003] Chinese patent publication number CN211968537U discloses a powder pressing machine for cosmetic production, which includes a frame for supporting the powder pressing machine, a rotating mechanism, a lower powder hopper, and a powder pressing mechanism. The rotating mechanism is arranged at the inner bottom of the frame, the lower powder hopper and the powder pressing mechanism are located above the rotating mechanism, and the lower powder hopper is located in front of the powder pressing mechanism. The machine also includes a powder extraction mechanism and a cleaning mechanism for sucking powder from the powder pressing machine. The powder extraction mechanism includes a filter box, an exhaust fan, a branch pipe, and a filter screen. The utility model uses a cleaning motor to drive a brush roller to rotate to clean excess powder on the turntable. At the same time, the exhaust fan and the branch pipe are used to pump the swept powder into the filter box, and the powder is filtered through the filter screen. The powder extraction mechanism and the cleaning mechanism can quickly clean and remove excess powder in the powder pressing machine, ensuring the cleanliness of the internal environment of the powder pressing machine. The collected powder can also be reused.

[0004] Regarding the above-mentioned related technologies, in the existing technology, the staff directly discharges the powder into the concave hole of the turntable through the lower powder hopper, and then uses the powder pressing mechanism to press the powder. However, in the process of the powder falling into the concave hole, there is a phenomenon that the amount of powder in the concave hole cannot be accurately controlled. The powder will fall on the turntable more or less, which may easily cause the volume of the molded powder to be different, thereby reducing the standardization of the powder processing. Utility Model Content

[0005] In order to improve the standardization of powder processing, the present application provides a pre-set forming mold.

[0006] This application provides a pre-molding mold using the following technical solutions:

[0007] A pre-formed molding die comprises a bottom plate on which a powder limiting barrel is placed. The top and bottom ends of the powder limiting barrel are both open. A limiting member is provided on the bottom plate to limit the movement of the powder limiting barrel. A compacting component for compacting powder is provided on the powder limiting barrel.

[0008] By adopting the above technical solution, when compacting the powder, the staff will place the powder limiting cylinder vertically on the bottom plate, then use the limiting member to limit the powder limiting cylinder, put a certain amount of powder into the powder limiting cylinder, and finally use the compacting component to compact the powder, achieving the effect of compacting the powder. Finally, remove the powder limiting cylinder to take out the molded powder. The staff will compact the fixed amount of powder to a certain degree by pre-setting the molding mold, so that the powder is initially formed, which facilitates the storage and transportation of the powder. In this way, when the powder pressing machine of the next process is carried out, the preliminarily formed powder can be directly processed, thus ensuring the amount of powder processed and making the volume of the molded powder after the powder pressing machine processing as consistent as possible, ensuring the quality of the molded powder, and improving the standardization of powder processing compared to the existing technology.

[0009] Optionally, the limiting member is a limiting plate, which is connected to the bottom plate, and a U-shaped groove is provided on the limiting member, and a limiting edge is provided on the side wall of the U-shaped groove, and the top wall of the limiting edge is flush with the top wall of the limiting member, and a limiting step is formed between the limiting edge and the side wall of the U-shaped groove, and a limiting ring groove is provided on the arc wall of the powder limiting barrel, and when the powder is compacted, the limiting edge is embedded in the limiting ring groove.

[0010] By adopting the above technical solution, the powder limiter may move or tilt during the compaction process, which can easily cause the powder to escape from the powder limiter. The staff placed the powder limiter vertically on the base plate and then moved the powder limiter so that the limiting edge was inserted into the limiting ring groove to limit the vertical freedom of the powder limiter, thus achieving the desired effect of limiting the powder limiter.

[0011] Optionally, the tamping assembly includes a first pressure column, which is plugged into the powder limiting cylinder.

[0012] By adopting the above technical solution, when compacting the powder, the staff puts a certain amount of powder into the powder limiting cylinder, then inserts the first pressure column into the powder limiting cylinder, and finally uses a tool to knock the top of the first pressure column. Finally, the powder limiting cylinder is removed to take out the molded powder, thereby achieving the effect of compacting the powder.

[0013] Optionally, the top end of the first pressure column is connected to an operating column.

[0014] By adopting the above technical solution, the operating column is used to facilitate the staff to use tools to knock, and it is also convenient for the staff to take the operating column after the powder is formed, so that the first pressure column is moved out of the powder limiting cylinder, thereby improving the operability of the first pressure column.

[0015] Optionally, the compacting assembly includes a second pressure column and a rotating sleeve, the second pressure column is inserted into the powder limiting barrel, the rotating sleeve is rotatably connected to the top end of the second pressure column, and the second pressure column is located in the rotating sleeve. When compacting the powder, the rotating sleeve is threadedly engaged with the powder limiting barrel.

[0016] By adopting the above technical solution, when compacting the powder, the staff puts a certain amount of powder into the powder limiting barrel, then inserts the second pressure column into the powder limiting barrel, and rotates the rotating sleeve so that the rotating sleeve thread fits on the powder limiting barrel, driving the second pressure column to move until the powder is compacted. The powder limiting barrel is removed to take out the formed powder, thereby achieving the effect of compacting the powder.

[0017] Optionally, a connecting ring is connected to the arc wall of the rotating sleeve at a position close to the top of the rotating sleeve, and a plurality of rotating notches are opened on the connecting ring.

[0018] By adopting the above technical solution, when the staff rotates the rotating sleeve, the surface of the rotating sleeve is smooth, and there is a risk of slipping when rotating the rotating sleeve, which may not achieve the initial compaction of the powder. By setting a connecting ring, the staff can rotate the rotating sleeve according to the rotating notch when operating the rotating sleeve, making it easier for the pre-set forming mold to achieve the powder compaction standard.

[0019] Optionally, the tamping assembly includes a third pressure column, a pressure rod and a connecting frame, the connecting frame is connected to the powder limiting barrel, the third pressure column passes through the connecting frame and is plugged into the powder limiting barrel, the top of the third pressure column is connected to a connecting block, a sliding groove is provided on the connecting block, one end of the pressure rod is rotatably connected to the connecting frame, the pressure rod is connected to a connecting column, the connecting column slides in the sliding groove, and the distance between one end of the pressure rod and the connecting column is smaller than the distance between the other end of the pressure rod and the connecting column.

[0020] By adopting the above technical solution, when compacting the powder, the staff puts a certain amount of powder into the powder limiting barrel, then presses the end of the pressure rod, and applies pressure to the third pressure column through the connecting column, so that the third pressure column descends and compacts the powder. Finally, the powder limiting barrel is removed to take the material, thereby achieving the effect of compacting the powder.

[0021] Optionally, a powder inlet notch is provided at the top of the powder limiting cylinder.

[0022] By adopting the above technical solution, the powder inlet gap is used to facilitate the staff to put the powder into the powder limiting barrel, thereby improving the convenience of placing the powder in the powder limiting barrel.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When compacting the powder, the staff will place the powder limiting cylinder vertically on the bottom plate, then use the limiting part to limit the powder limiting cylinder, put a certain amount of powder into the powder limiting cylinder, and finally use the compacting component to compact the powder to achieve the effect of compacting the powder. Finally, remove the powder limiting cylinder to take out the molded powder. The staff will compact the fixed amount of powder to a certain degree by pre-setting the molding mold, so that the powder is initially formed, which is convenient for the storage and transportation of the powder. In this way, when the powder pressing machine is used in the next process, the preliminarily formed powder can be directly processed, which ensures the amount of powder processed and keeps the volume of the molded powder after the powder pressing machine as consistent as possible, ensuring the quality of the molded powder. Compared with the existing technology, the standardization of powder processing is improved;

[0025] 2. When compacting the powder, the worker puts a certain amount of powder into the powder limiting barrel, then inserts the second pressure column into the powder limiting barrel and rotates the rotating sleeve so that the rotating sleeve thread fits on the powder limiting barrel, driving the second pressure column to move until the powder is compacted. After that, the powder limiting barrel is removed to take out the formed powder, thus achieving the effect of compacting the powder.

[0032] The following is combined with Figures 1-4 This application is described in further detail.

[0033] Example 1 of the present application discloses a pre-molding mold. Figure 1 The pre-molding mold includes a bottom plate 1, on which a limited powder cylinder 2 is vertically placed, and the top and bottom ends of the limited powder cylinder 2 are both opened.

[0034] Reference Figure 1 and Figure 2 The base plate 1 is provided with a limiting member 3, which is a limiting plate and is bolted to the base plate 1. The limiting member 3 has a U-shaped groove 31, and a limiting edge 32 is fixedly connected to the side wall of the U-shaped groove 31. The limiting edge 32 forms a limiting step with the side wall of the U-shaped groove 31, and the top wall of the limiting edge 32 is flush with the top wall of the limiting member 3. A limiting ring groove 21 is formed in the powder limiting barrel 2 at the position corresponding to the limiting edge 32, and the limiting edge 32 is embedded in the limiting ring groove 21.

[0035] The staff uses the cooperation between the limiting edge 32 and the limiting ring groove 21 to limit the vertical freedom of the powder limiting barrel 2, reducing the possibility of the powder limiting barrel 2 being tilted by force.

[0036] Reference Figure 1 and Figure 2 The powder limiting barrel 2 is provided with a tamping assembly 4, which includes a first pressure column 41. The first pressure column 41 is inserted into the powder limiting barrel 2, and the top of the first pressure column 41 is fixedly connected to an operating column 411. The operating column 411 is used to facilitate the staff to use tools to strike or take the first pressure column 41, thereby improving the operability of the first pressure column 41.

[0037] The implementation principle of a pre-set forming mold in Example 1 of the present application is: when compacting the powder, the staff places the powder limiting barrel 2 on the bottom plate 1, then moves the powder limiting barrel 2 so that the limiting edge 32 is embedded in the limiting ring groove 21, and then puts a certain amount of powder into the powder limiting barrel 2, and then inserts the first pressure column 41 into the powder limiting barrel 2, and then uses a tool to knock the operating column 411 to compact the powder into shape, and then takes out the powder limiting barrel 2, and then takes out the formed powder, thereby achieving the effect of preliminarily compacting the powder into shape.

[0038] The staff uses pre-set molding molds to compact the quantitative powder to a certain degree, so that the powder is initially formed, which facilitates the storage and transportation of the powder. In this way, when the powder pressing machine is used in the next process, the preliminarily formed powder can be directly processed. This ensures the amount of powder processing and keeps the volume of the molded powder after processing by the powder pressing machine as consistent as possible, ensuring the quality of the molded powder. Compared with the existing technology, the standardization of powder processing is improved.

[0039] Example 2: The difference between this example and Example 1 lies in the different structure of the compacting assembly 4 .

[0040] Reference Figure 3The compacting assembly 4 includes a second pressure column 42 and a rotating sleeve 43. The second pressure column 42 is inserted into the powder limiting barrel 2, and the rotating sleeve 43 is connected to the top of the second pressure column 42 through a bearing. The second pressure column 42 is located in the rotating sleeve 43, and the rotating sleeve 43 is threadedly engaged with the powder limiting barrel 2.

[0041] Reference Figure 3 To reduce slippage when rotating the rotating sleeve 43, a connecting ring 431 is fixedly connected to the arc wall of the rotating sleeve 43 near the top of the rotating sleeve 43. The connecting ring 431 has a plurality of rotation notches 432 along its circumference. The rotation notches 432 are used to facilitate the staff to rotate the rotating sleeve 43.

[0042] When compacting the powder, the staff puts a certain amount of powder into the powder limiting barrel 2, then inserts the second pressure column 42 into the powder limiting barrel 2, rotates the rotating sleeve 43, and makes the rotating sleeve 43 threadedly engage with the powder limiting barrel 2, driving the second pressure column 42 to descend until the powder is compacted and formed. Finally, the powder limiting barrel 2 is taken out, and the formed powder can be taken out, achieving the effect of compacting the powder.

[0043] Example 3: The difference between this example and Example 1 lies in the different structure of the compacting assembly 4 .

[0044] Reference Figure 4 The tamping assembly 4 includes a third pressure column 44, a pressure rod 45 and a connecting frame 46. The connecting frame 46 is fixedly connected to the top of the powder limiting barrel 2. The third pressure column 44 passes through the connecting frame 46 and is plugged into the powder limiting barrel 2. One end of the pressure rod 45 is hinged on the connecting frame 46, and a connecting groove is provided on the pressure rod 45, in which a connecting column 451 is fixedly connected. The top of the third pressure column 44 is fixedly connected to a connecting block, and a sliding groove is provided on the connecting block, in which the connecting column 451 slides. The distance between one end of the pressure rod 45 and the connecting column 451 is smaller than the distance between the other end of the pressure rod 45 and the connecting column 451.

[0045] Reference Figure 4 In order to facilitate the staff to place the powder, a powder inlet notch 22 is opened at the top of the powder limiting cylinder 2. The powder inlet notch 22 is used to guide the powder into the powder limiting cylinder 2, providing convenience for the staff to place the powder.

[0046] When compacting the powder, the staff puts a certain amount of powder into the powder limiting cylinder 2 through the powder inlet notch 22, and then presses the other end of the pressure rod 45, so that the connecting column 451 presses the top of the third pressure column 44, so that the third pressure column 44 compacts the powder, and finally takes out the powder limiting cylinder 2, and the molded powder can be taken out, achieving the effect of compacting the powder.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
