Description

Technical Field

[0001] This utility model relates to the field of nipple processing technology, specifically a liquid silicone nipple molding die with a breast-like structure. Background Technology

[0002] With the continuous innovation of infant feeding concepts, parents have placed higher demands on the safety and functionality of baby products. As an essential tool for daily infant feeding, the design and quality of pacifiers directly affect the healthy growth of infants. Traditional pacifiers have limitations in simulating the breastfeeding experience, while liquid silicone pacifiers with a breast-like structure, closely resembling the shape, feel, and sucking characteristics of real breast milk, are gradually becoming a new favorite in the market.

[0003] For example, the patent with national authorized patent announcement number CN207859382U discloses a thermoforming mold for a nipple, which includes a fixed mold and a moving mold that communicate with the injection molding channel. The moving mold is provided with several mold cores, each mold core having a hemispherical protruding end that extends smoothly into a concave cone shape towards the bottom of the mold core. The diameter of the lowest end of the mold core is smaller than the diameter of the outer wall of the mold core seat. The lowest end of the mold core is recessed inward to form an annular recessed area with a sidewall depth of no more than 2mm, and the height of the upper edge of the annular recessed area is flush with the height of the outer wall of the moving mold core seat. The fixed mold is provided with several mold cavities that match the mold cores. Each mold cavity has an annular protrusion at its outer end. The annular protrusion is located in the center of the annular recessed area and is positioned opposite to it. The distance between the sidewall of the annular protrusion and the sidewall of the annular recess is 1.5-2.5mm, and the thickness of the annular protrusion does not exceed the thickness of the annular recess. By modifying the mold core and mold cavity, and adjusting the relative positions of the positioning pins, positioning holes and the mold core and mold cavity, the strength of the nipple can be effectively improved after the liquid silicone is made into a nipple.

[0004] However, the thermoforming mold for the aforementioned nipple cannot automatically demold the formed nipple during the cooling and molding process and when the mold is opened. Because it cannot be automatically demolded, the nipple needs to be manually removed from the mold, which increases the time for manual operation in each production cycle and reduces production efficiency. Utility Model Content

[0005] The purpose of this invention is to provide a liquid silicone nipple molding mold with a breast-like structure, in order to solve the problem mentioned in the background art that the molded nipple cannot be automatically demolded during the cooling and molding process and mold opening. Because it cannot be automatically demolded, the nipple needs to be manually removed from the mold, which reduces production efficiency.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A liquid silicone nipple molding die with a breast-like structure includes: a base, a connecting block fixedly installed on the upper surface of the base, a mold cavity opened on the upper surface of the connecting block, a filling mechanism inserted into the mold cavity, and a groove formed between the mold cavity and the filling mechanism, the filling mechanism being fixedly installed on the lower surface of a top cover, the top cover being slidably installed on the outer surface of four sets of sliding pillars, and the sliding pillars being fixedly installed on the upper surface of the base.

[0008] As a preferred embodiment of this utility model, electric push rods are fixedly installed at both ends of the upper surface of the base, and the upper surfaces of the piston rods of the two sets of electric push rods are fixedly connected to the lower surface of the top cover.

[0009] As a preferred embodiment of this utility model, the upper surface of the top cover is provided with an injection channel, and the injection channel is connected to the mold cavity.

[0010] As a preferred embodiment of this utility model, the top cover can slide and cover the outer surface of the connecting block, and can touch the upper surface of the stop plate as the electric push rod is continuously pulled down, the stop plate being fixedly installed on the outer surface of the connecting block.

[0011] In a preferred embodiment of this utility model, the filling mechanism includes a lifting column, which is fixedly installed on the lower surface of the top cover. A connecting plate is slidably installed on the outer surface of the lifting column, and a core is fixedly installed on the lower surface of the connecting plate. The core can be driven by the top cover to be inserted and suspended in the mold cavity, forming a groove between the mold cavity and the core. The lifting column is also driven to slide into the docking groove, which is opened on the upper surface of the connecting block.

[0012] As a preferred embodiment of this utility model, a convex ring is fixedly installed on the outer surface of the core, so that the cooled and cured silicone nipple can be held on the outer surface of the core through the convex ring, and can be lifted out of the mold cavity.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] 1. Through the design of the base, top cover, mold cavity, electric push rod, stop plate, and filling mechanism, during use, the electric push rod is activated to insert the top cover into the outer surface of the connecting block until the top cover touches the upper surface of the stop plate. The top cover then drives the filling mechanism, which is fixedly installed on the lower surface, to be inserted into the mold cavity opened on the upper surface of the connecting block. This creates a nipple groove between the filling mechanism and the mold cavity. Then, the operator can pour liquid silicone into the injection channel opened on the upper surface of the top cover, allowing the liquid silicone to flow into the mold cavity and cool and solidify to form a nipple. The solidified nipple hangs on the outer surface of the filling mechanism. During the mold opening process, the electric push rod pushes the top cover, allowing the top cover to pull the nipple hanging on the outer surface of the filling mechanism out of the mold cavity. This enables the electric push rod to automatically open and demold, replacing the cumbersome manual demolding process, greatly shortening the production cycle of a single product and increasing the output per unit time.

[0015] 2. Through the design of the connecting plate, core, convex ring, and lifting column, during nipple production, the top cover sleeve is pulled against the outer surface of the connecting block by activating the electric push rod until the top cover touches the upper surface of the stop plate. During this process, the top cover drives the connecting plate, which is slidably mounted on the outer surface of the lifting column, to touch the upper surface of the connecting block. This allows the connecting block to drive the core, which is fixedly mounted on the lower surface, into the mold cavity. As the top cover continues to pull down, the connecting plate is stopped on the outer surface of the connecting block, and the lifting column slides into the mating groove. The core inserted into the mold cavity forms the nipple groove. Then, the operator can pour liquid silicone into the injection channel opened on the upper surface of the top cover, allowing the liquid silicone to fill the mold cavity along the channel and solidify during the cooling process. In this process, because the protruding ring on the outer surface of the core protrudes from the core body, the cured silicone nipple can be wrapped around the outer surface of the protruding ring, thus firmly hanging on the outer surface of the core. Then, during the process of opening the mold by pushing the top cover with an electric push rod, the top cover can drive the lifting column to be pulled out from the docking groove. The lifting column can then drive the connecting plate that is slidably mounted on the outer surface to be lifted up. The connecting plate can then drive the core on the lower surface to be lifted out of the mold cavity. In turn, the core can drive the nipple hanging on the outer surface to be lifted out of the mold cavity, thus achieving the purpose of automatic demolding. This allows the workers to directly remove the hanging nipple to complete the production process. Furthermore, the process of mold closing, mold opening, and demolding is realized by pushing and pulling the electric push rod, thereby reducing the downtime in the production process and increasing production efficiency.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 This utility model provides a technical solution:

[0023] like Figures 1-3 As shown, a liquid silicone nipple molding die with a breast-like structure includes: a base 1, a connecting block 101 fixedly installed on the upper surface of the base 1, a mold cavity 102 opened on the upper surface of the connecting block 101, a filling mechanism 2 inserted into the mold cavity 102, and a groove formed between the mold cavity 102 and the filling mechanism 2, the filling mechanism 2 being fixedly installed on the lower surface of the top cover 103, the top cover 103 being slidably installed on the outer surface of four sets of sliding pillars 104, and the sliding pillars 104 being fixedly installed on the upper surface of the base 1.

[0024] Electric push rods 105 are fixedly installed at both ends of the upper surface of the base 1, and the upper surfaces of the piston rods of the two sets of electric push rods 105 are fixedly connected to the lower surface of the top cover 103.

[0025] An injection channel is provided on the upper surface of the top cover 103, and the injection channel is connected to the mold cavity 102.

[0026] The top cover 103 can slide and cover the outer surface of the connecting block 101, and can touch the upper surface of the stop plate 106 as the electric push rod 105 is continuously pulled down. The stop plate 106 is fixedly installed on the outer surface of the connecting block 101.

[0027] Through the design of the base 1, top cover 103, mold cavity 102, electric push rod 105, stop plate 106, and filling mechanism 2, during use, the electric push rod 105 is activated to insert the top cover 103 onto the outer surface of the connecting block 101 until the top cover 103 touches the upper surface of the stop plate 106 and stops. The top cover 103 then drives the filling mechanism 2, which is fixedly installed on the lower surface, to be inserted into the mold cavity 102 opened on the upper surface of the connecting block 101. This creates a nipple-like groove between the filling mechanism 2 and the mold cavity 102, allowing the operator to pour liquid silicone into the top cover. Liquid silicone flows into the mold cavity 102 through the injection channel on the upper surface of 103, where it is cooled and solidified to form a nipple. The solidified nipple hangs on the outer surface of the filling mechanism 2. Then, when the electric push rod 105 pushes the top cover 103 to open the mold, the top cover 103 can pull the nipple hanging on the outer surface of the filling mechanism 2 out of the mold cavity 102 and demold it. Thus, the push of the electric push rod 105 can realize the automatic mold opening and demolding action, replacing the cumbersome manual demolding process, greatly shortening the production cycle of a single product and increasing the output per unit time.

[0028] like Figure 4 As shown, the filling mechanism 2 includes a lifting column 204, which is fixedly installed on the lower surface of the top cover 103. A connecting plate 201 is slidably installed on the outer surface of the lifting column 204. A core 202 is fixedly installed on the lower surface of the connecting plate 201. The core 202 can be driven by the top cover 103 to be inserted and suspended in the mold cavity 102, forming a groove between the mold cavity 102 and the core 202. The lifting column 204 is also driven to slide into the docking groove 107, which is opened on the upper surface of the connecting block 101.

[0029] A raised ring 203 is fixedly installed on the outer surface of the core 202, so that the cooled and cured silicone nipple can be held on the outer surface of the core 202 by the raised ring 203, so that it can be lifted out of the mold cavity 102.

[0030] Through the design of the connecting plate 201, core 202, convex ring 203, and lifting column 204, during nipple production, the top cover 103 can be pulled onto the outer surface of the connecting block 101 by activating the electric push rod 105 until the top cover 103 touches the upper surface of the stop plate 106. During this process, the top cover 103 can drive the connecting plate 201, which is slidably mounted on the outer surface of the lifting column 204, to touch the upper surface of the connecting block 101, thereby enabling the connecting block 101 to... 1. The core 202, fixedly mounted on the lower surface, is inserted into the mold cavity 102. As the top cover 103 continues to pull down, the connecting plate 201 is stopped on the outer surface of the connecting block 101, and the lifting column 204 slides into the docking groove 107. The core 202 inserted into the mold cavity 102 forms a nipple groove, allowing the operator to pour liquid silicone into the injection channel on the upper surface of the top cover 103, filling the mold cavity 102 along the channel. During the cooling and curing process, because the protruding ring 203 on the outer surface of the core 202 protrudes from the core 202 body, the cured silicone nipple can wrap around the outer surface of the protruding ring 203, thus firmly hanging on the outer surface of the core 202. Subsequently, during the mold opening process, the electric push rod 105 can push the top cover 103, which can drive the lifting column 204 to be pulled out from the docking groove 107. The lifting column 204 can then drive the connecting plate 2, which is slidably mounted on the outer surface. 01. When the mold is lifted, the connecting plate 201 can pull the core 202 on the lower surface out of the mold cavity 102, which in turn can pull the nipple hanging on the outer surface out of the mold cavity 102, thus achieving automatic demolding. This allows the staff to directly remove the hanging nipple to complete the production process. Furthermore, the process of mold closing, mold opening, and demolding can be realized by pushing and pulling the electric push rod 105, thereby reducing downtime in the production process and increasing production efficiency.

[0031] Based on the above technical solution, the working steps of this solution are summarized as follows: In use, the electric push rod 105 is activated to pull the top cover 103 onto the outer surface of the connecting block 101 until the top cover 103 touches the upper surface of the stop plate 106. During this process, the top cover 103 drives the connecting plate 201, which is slidably mounted on the outer surface of the lifting column 204, to touch the upper surface of the connecting block 101. This allows the connecting block 101 to drive the core 202, which is fixedly mounted on its lower surface, into the mold cavity 102. As the top cover 103 continues to pull down, the connecting plate 201 is stopped on the outer surface of the connecting block 101, and the lifting column 204 slides into the mating groove 107. The core 202 inserted into the mold cavity 102 forms a nipple groove, allowing the operator to pour liquid silicone into the injection port on the upper surface of the top cover 103. Liquid silicone fills the mold cavity 102 through the flow channel. During cooling and curing, the protruding ring 203 on the outer surface of the core 202 protrudes from the core 202 body, allowing the cured silicone nipple to wrap around the outer surface of the protruding ring 203, thus firmly holding it on the outer surface of the core 202. Subsequently, the electric push rod 105 pushes the top cover 103 to open the mold, causing the top cover 103 to pull the lifting column 204 out of the docking groove 107. The lifting column 204 then lifts the connecting plate 201 that is slidably mounted on the outer surface, which in turn lifts the core 202 on the lower surface out of the mold cavity 102. This allows the core 202 to pull the nipple held on the outer surface out of the mold cavity 102, achieving automatic demolding. The nipple can then be easily removed by the operator, completing the production process.

[0032] In summary, by pushing and pulling the electric push rod 105, the automatic mold closing, mold opening, and demolding processes are realized, thereby reducing downtime in the production process and increasing production efficiency.
