Description

Technical Field

[0001] The present application relates to the technical field of facial mask molds, and specifically to a bead-bursting facial mask forming mold. Background Art

[0002] With the booming beauty and skincare industry, facial masks, a beloved skincare product, continue to see increasing market demand. Molds are a key component of facial mask production, and their quality and performance play a crucial role in determining both the quality and efficiency of the mask.

[0003] During the production process of facial masks, the mask is formed by sending the mold into a cooling tunnel for cooling. During the curing and molding stage, the traditional cooling tunnel cooling method has certain defects. The cooling tunnel has a large space and a complex structure. It is difficult for the cooling medium (such as cold air) to flow evenly and stably in the tunnel, which makes the cooling rate of different parts of the mold inconsistent during the cooling process. For facial mask molds containing beads and hydrogels, this temperature difference will lead to uneven stress distribution inside the mask. On the one hand, it may cause the degree of solidification of the hydrogel around the beads to be different from that of other parts, affecting the touch and efficacy of the mask; on the other hand, during the subsequent cooling and demolding, due to stress concentration, the mask is prone to defects such as cracking and deformation, which seriously affects the yield rate of the product. Therefore, it is necessary to provide a bead-bursting facial mask molding mold to solve the above problems.

[0035] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0036] In order to enable those skilled in the art to better understand the present invention, the following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments in the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of this application.

[0037] Example 1

[0038] The present invention discloses a facial mask with popping beads for application to the human face. The mask comprises a membrane cloth 1 and popping beads 2. Specifically, the membrane cloth 1 has a skin-friendly layer 3 adapted to fit the human face. The skin-friendly layer 3 has eye slots 4, nose slots 5, and mouth slots 6 formed in positions corresponding to the eyes, nose, and mouth, respectively. The eye slots 4, nose slots 5, and mouth slots 6 all penetrate the membrane cloth 1.

[0039] There are a plurality of bursting beads 2 distributed on the surface of the skin-friendly layer 3. When the membrane 1 is applied to the human face, the bursting beads 2 come into contact with the skin. The bursting beads 2 have a cavity with a diameter of 3 mm, which is used to encapsulate the active ingredients and then burst them out when used, which can have a "freshness-locking" effect and prevent the active ingredients from being oxidized and hydrolyzed. Those skilled in the art can inject active ingredients with different effects according to specific needs.

[0040] Specifically, the spacing between two adjacent bursting beads 2 is 2 mm or 20 mm;

[0041] Specifically, the bead mask has a thickness of 3 mm or 25 mm.

[0042] The popping beads in this application use a specific hydrogel material as the shell, and are filled with essence and vitamin C. This hydrogel material is made of carrageenan, alginate and gum mixed in a specific proportion. Carrageenan has good gel properties, alginate can enhance the flexibility and hydrophilicity of the hydrogel, and gum helps to improve the stability of the overall structure. The three work together to form a hydrogel film with specific mechanical properties and barrier properties. It can not only effectively wrap the essence inside, but also ensure that the popping beads will break under moderate external force during the use of the mask, releasing the essence and providing effective nourishment for the skin. In addition, the hydrogel material has good compatibility with the hydrogel and other ingredients of the mask body, and does not affect the overall production process and product quality of the mask.

[0049] More specifically, the distance between two adjacent bursting beads 2 is 6 mm or 12 mm;

[0050] Specifically, the bursting bead mask has a thickness of 15 mm.

[0051] Example 4

[0052] like Figure 1-Figure 3As shown, the present application provides a bead-bursting facial mask forming mold, including a mold assembly 100, the mold assembly 100 having a lower mold 11, the lower mold 11 having a bead-bursting positioning hole, and four groups of pillars 12 fixedly mounted on the lower mold 11, and a top plate 13 fixedly mounted at one end of the pillar 12, and four groups of limiting pillars (not shown in the figure) fixedly mounted on a side of the top plate 13 close to the lower mold 11, while an upper mold 15 is movably sleeved on the four groups of limiting pillars, and a hydraulic cylinder 14 is fixedly mounted on a side of the top plate 13 away from the lower mold 11, and the telescopic end of the hydraulic cylinder 14 passes through the top plate 13 and is connected to the upper mold 15;

[0053] Thus, the upper mold 15 is adapted to move along with the telescopic end of the hydraulic cylinder 14 to approach or move away from the lower mold 11, thereby achieving the pressing of the mask cloth or the restriction of the hydrogel;

[0054] In order to solidify the bead mask, Figure 2-Figure 3 As shown, a cooling chamber 17 is defined at the bottom of the lower mold 11, and a water-cooling assembly 200 is disposed within the cooling chamber 17 to cool the lower mold 11. The water-cooling assembly 200 includes a support frame 21 secured within the cooling chamber 17, upon which are mounted a plurality of tube clamps 22. The tube clamps 22 are composed of an arc-shaped support and an arc-shaped limiting rod. The arc-shaped limiting rod can be inserted through the arc-shaped support, and fasteners are threaded at both ends of the arc-shaped limiting rod for securing the tube clamps.

[0055] S-shaped cooling tubes 26 are arranged between the multiple sets of tube clamps 22. Connected to these tubes are multiple sets of nozzles 23, which spray liquid onto the inner wall of cooling chamber 17. The spraying action of nozzles 23 ensures that the cooling medium fully contacts the inner wall of cooling chamber 17, thereby cooling the mask on lower mold 11 and improving the quality of the cured mask.

[0056] At the same time, a filter screen 27 is provided inside the cooling chamber 17 and at the lower end of the cooling pipe 26. The filter screen 27 is mainly used to filter the water that is sprayed by the nozzle 23 and falls after contacting the inner wall of the cooling chamber 17, so as to ensure the cleanliness of the cooling medium and maintain the stable operation of the cooling system.

[0057] In order to receive the water source after spraying and cool it in one step, continue to refer to Figure 2-Figure 3As shown, a base 16 is connected and installed at the bottom end of the lower mold 11, and a cooling component 300 is embedded on a surface of the base 16 close to the lower mold 11. The cooling component 300 includes a cooling box 31 embedded on the base 16. A storage tank (not marked in the figure) is provided at the center of the cooling box 31. The storage tank contains cooling water in the initial state and is also used to collect water that falls after being sprayed by the nozzle 23 and contacting the inner wall of the cooling chamber 17.

[0058] The cooling pipe 26 also has a water inlet and a water outlet, each of which is equipped with a water pump (not shown). The water pump at the water inlet is connected to the first connecting pipe 24, one end of which is connected to the storage tank, thereby transporting water collected in the storage tank to the cooling pipe 26. The water pump at the water outlet is connected to the second connecting pipe 25, one end of which is also connected to the storage tank, allowing the water circulated through the cooling pipe 26 to flow back to the storage tank.

[0059] From a practical perspective, after the nozzle 23 sprays the top of the inner wall of the cooling chamber 17, the water, upon contacting the inner wall, falls due to gravity into the storage tank of the cooling box 31 for collection. At this point, the water pump at the water inlet is activated, pumping the water in the storage tank to the cooling pipe 26 via the first connecting pipe 24. Simultaneously, the water pump at the water outlet, via the second connecting pipe 25, pumps the cooled water back to the storage tank. This cycle repeats, continuously recycling the water in the storage tank.

[0060] In the present application, a first liquid level sensor is provided in the storage tank of the cooling box 31, and a connecting nozzle is installed through the side of the base 16. The connecting nozzle is connected to the storage tank of the cooling box 31. The first liquid level sensor is used to detect the cooling water level in the storage tank to prevent the cooling water from being repeatedly used in the circulation process. The first liquid level sensor continuously detects the liquid level. Once the liquid level falls below the set threshold, cooling water can be added through the connecting nozzle to maintain a continuous water cooling effect on the lower mold 11.

[0061] It should be noted that the mask mold requires the lower mold 11 to be insulated before the mask is formed. Therefore, according to actual usage needs, a heat medium can be supplied through a water pump in the first connecting pipe 24. During the circulation of the heat medium in the pipe, the first connecting pipe 24 is heated by heat conduction, thereby increasing the surface temperature of the first connecting pipe 24, thereby increasing the temperature of the storage tank, and ultimately indirectly heating the bottom surface of the lower mold 11, achieving a good insulation effect. During the initial insulation stage, the valve provided at the connection between the nozzle 23 and the first connecting pipe 24 is in a closed state; when entering the subsequent cooling process, the valve will be opened;

[0062] In addition, a certain number (the number ranges from 1 to 50, and the more common number ranges from 1 to 30) of glue injection channels are distributed on the bottom and around the lower mold 11 (refer to Figure 2 The setting of these injection channels is designed to ensure that the glue can be injected evenly, thereby achieving precise control of the thickness of the mask.

[0063] The cooling box 31 also features a circular groove 33, which surrounds the reservoir and stores coolant. A sealing cover 32 with a circular structure is attached to the cooling box 31 via fasteners. This seals the groove 33, preventing coolant leakage and ensuring the cooling system's tightness and stability.

[0064] In the present application, a second liquid level sensor is provided in the meandering groove 33, and a valve is installed in communication with the meandering groove 33. The valve is provided through the base 16. The second liquid level sensor is used to detect the liquid level of the coolant in the meandering groove 33 to prevent the liquid level from dropping due to loss or other reasons as the coolant is used multiple times in the circulation process. The second liquid level sensor continuously detects the liquid level. Once the liquid level is lower than the set threshold, cooling water can be added through the valve to maintain the cooling effect on the coolant.

[0065] Two sets of mixing units are mounted on the sides of the base 16. Each set of mixing units includes a drive member 34 fixed to the side of the base 16, with the output end of the drive member 34 extending into the interior of the storage tank. A stirring blade 35 is fixedly mounted at the output end of the drive member 34. When the drive member 34 is in operation, its output end drives the stirring blade 35 to rotate synchronously, promoting the full flow of cooling water within the storage tank and thereby fully contacting the wall of the meandering groove 33. This achieves efficient cooling through heat conduction, thereby improving the cooling efficiency of the cooling water.

[0066] In order to maintain the cooling performance of the coolant, cooling units are installed on both sides of the base 16. The cooling unit is mainly composed of a circulation pump 36 fixedly mounted on the side of the base 16. The circulation pump 36 has an inlet end and an outlet end, and a right-angle tube 37 is connected to both the inlet end and the outlet end, and one end of the right-angle tube 37 is connected to the circular groove 33, thereby forming a circulation channel for the coolant. In addition, a dust cover 38 is sleeved on the base 16, and an inner groove is provided at the bottom of the dust cover 38. An air-cooled radiator 39 is fixedly mounted in the inner groove. The air-cooled radiator 39 consists of a heat sink and a fan, and the fan is set facing the right-angle tube 37.

[0067] During operation, the coolant, driven by a circulation pump 36, circulates through a right-angled tube 37 between the serpentine groove 33 and the air-cooled radiator 39. As the coolant flows through the fins of the air-cooled radiator 39, the fan operates to force air to flow through the fins, accelerating the dissipation of heat from the coolant into the air. This effectively lowers the coolant's temperature, ensuring consistent cooling performance and providing stable and efficient cooling support for the cooling process during mask production.

[0068] In the technical solution involved in this application, considering the needs of large-scale production, the mold assemblies 100 can be arranged in multiple groups. To achieve the coordinated operation between the multiple groups of mold assemblies 100 and ensure that the cooling process can efficiently process the masks in batches, interconnecting pipes can be connected between the multiple groups of mold assemblies 100. Through these interconnecting pipes, a coherent cooling medium flow path can be established, allowing the cooling medium to flow in an orderly manner between different mold assemblies 100, thereby achieving batch cooling of the masks, greatly improving production efficiency and meeting the requirements of large-scale production.

[0069] In summary, this mold achieves uniform cooling of all areas of the mask by installing a cooling device within the lower mold 11, specifically by spraying the cooling medium uniformly onto the top of the inner wall of the cooling chamber 17 from the nozzle 23 in the water-cooling assembly 200. This effectively prevents the hydrogel around the beads from solidifying to different degrees than other areas, ensuring consistent feel and efficacy of the mask. It also addresses the stress concentration caused by uneven cooling, significantly reduces defects such as cracking and deformation during cooling and demolding, and significantly improves the product yield.

[0070] At the same time, through the circulation of cooling tube 26, filtration by filter 27, water replenishment monitored by liquid level sensors, and the coordinated action of the mixing unit and cooling unit, efficient recycling of the cooling medium and precise temperature control are achieved. The water in cooling tube 26 continuously circulates, the mixing unit accelerates heat transfer between the cooling water and the coolant, and the cooling unit maintains the cooling performance of the coolant, ensuring a stable and efficient cooling process. Compared to traditional cooling tunnels, this significantly shortens the curing time of the facial mask, improves production efficiency, and ensures consistent cooling effects for each batch of products, facilitating large-scale and stable production for enterprises.

[0071] By integrating cooling devices into the mold, reliance on large cooling tunnels is reduced. This not only lowers equipment procurement and installation costs but also reduces the equipment footprint. Furthermore, the mold's cooling system automatically replenishes water and coolant via level sensors and valves, minimizing manual intervention, reducing labor costs and production risks associated with human error, and improving the cost-effectiveness and reliability of the entire production process.
