Description

Technical Field

[0001] This utility model relates to the field of silicone processing technology, specifically to a multi-hole punch device for micro-hole molding of silicone nipples. Background Technology

[0002] In the field of infant and toddler products, silicone nipples are an important tool for infant feeding, and their quality and performance are of great concern. The microporous structure of silicone nipples plays a key role in the smoothness of milk flow, the effect of preventing choking, and the comfort of infant sucking. Therefore, the microporous molding technology of silicone nipples has always been a research focus in this field.

[0003] Existing silicone nipple microporous molding equipment and processes have many shortcomings. On the one hand, during the molding process, due to the lack of an effective buffering mechanism, the punch often generates a large impact force when it comes into contact with the silicone nipple, which can easily cause tearing and deformation of the nipple material, reduce the product qualification rate, and increase production costs.

[0004] On the other hand, the design and layout of the steel needles in traditional punching devices are not ideal. Uneven force distribution on the needles during punching results in poor consistency in the forming of each micro-hole, making it difficult to meet the production requirements of high-quality silicone nipples. Furthermore, the transmission of pressure to the steel needles is not precise enough, leading to uneven punching and impacting production efficiency. Moreover, after the silicone nipples are formed, most equipment uses manual removal, which is not only inefficient and unable to meet the needs of large-scale production, but also prone to damaging the nipples during removal, affecting the product's appearance quality and yield.

[0005] To address the aforementioned issues, this paper proposes a multi-hole punch device for microporous molding of silicone nipples. Utility Model Content

[0006] The present invention aims to solve the problems mentioned in the background art by providing a multi-hole punch device for micro-hole molding of silicone nipples.

[0007] The specific technical solution is as follows:

[0008] A multi-hole punch device for micro-hole molding of silicone nipples includes a base, a top plate fixedly installed on the top of the base by a bracket, a cylinder installed on the bottom center of the top plate by bolts, a movable plate installed on the lower end of the piston rod of the cylinder by bolts, and a plurality of punching components installed on the bottom of the movable plate.

[0009] Each punching assembly includes a round rod and several steel needles. The upper end of the round rod moves through the movable plate, and the lower end of the round rod is fixedly installed with a core. The lower ends of the steel needles move through the core and extend below the core.

[0010] The base is fixedly mounted with a lower mold on its top by a support column. The lower mold has a molding cavity that corresponds one-to-one with the core for placing the silicone nipple. The lower mold also has a steel needle insertion hole for inserting a steel needle.

[0011] It also includes an air-blowing ejection mechanism that lifts up the silicone nipple.

[0012] As a preferred embodiment of this utility model, the steel needles are divided into left and right groups by the round rod as the dividing point, and a connecting block is fixedly installed on the top of the steel needles in both the left and right groups.

[0013] As a preferred embodiment of this utility model, an anti-detachment plate is installed on the top of the round rod, and the anti-detachment plate is located above the moving plate.

[0014] As a preferred embodiment of this utility model, the top outer wall of the round rod is provided with external threads, the bottom center of the anti-detachment plate is provided with a threaded hole, and the top of the round rod is screwed into the inside of the threaded hole.

[0015] In a preferred embodiment of this utility model, a spring is fitted around the outside of the round rod, and the spring is located between the moving plate and the core.

[0016] As a preferred embodiment of this utility model, the air-blowing ejection mechanism includes an air pump installed at the bottom of the lower mold, and the interior of the lower mold is provided with a ventilation groove communicating with the steel needle insertion hole. The air outlet of the air pump is connected to the ventilation groove through a pipe.

[0017] As a preferred embodiment of this utility model, at least two limiting rods are installed at equal intervals on the top of the movable plate, and the upper ends of the limiting rods move through the top plate.

[0018] This utility model has the following beneficial effects:

[0019] This multi-hole punch device is used for microporous molding of silicone nipples.

[0020] Improve product quality:

[0021] The top of the round rod is screwed to the threaded hole of the anti-detachment plate via an external thread. The anti-detachment plate is located above the moving plate to prevent the round rod from detaching from the moving plate. The spring fitted on the outside of the round rod is located between the moving plate and the core. During stamping, the core gradually increases the pressure on the silicone nipple. The buffering effect prevents the steel needle from causing excessive impact on the silicone nipple, preventing tearing and deformation of the nipple material and improving the product qualification rate.

[0022] The steel needles are divided into left and right groups by a circular rod, and the top is fixed by a connecting block. The connecting block serves two purposes: firstly, it ensures more even force distribution on the steel needles during the stamping process, guaranteeing consistent forming of each micro-hole and improving product quality; secondly, during the punching stage, after the moving plate presses down and contacts the connecting block, it pushes the steel needles through the silicone nipple by pressing down on the connecting block, thus transmitting pressure and ensuring smooth punching.

[0023] The molding cavities on the lower mold correspond one-to-one with the core and are used to place the silicone nipple. Precise positioning ensures that the silicone nipple is accurately positioned during stamping, allowing the steel needle to punch out micro-holes according to the preset position and shape, thereby improving the product molding accuracy and quality stability.

[0024] The steel needle insertion hole not only provides a precise insertion channel for the steel needle, ensuring that the steel needle penetrates the silicone nipple vertically and accurately during stamping, avoiding bending or deviation of the steel needle, and ensuring that the shape and size of the micro-hole meet the design requirements, thus improving the product yield; it also connects with the ventilation groove and acts as an air jet channel in the air-blowing ejection mechanism to eject the molded silicone nipple from the molding cavity.

[0025] Improve production efficiency:

[0026] The design of multiple molding cavities on the lower mold allows for the simultaneous stamping of multiple silicone nipples, improving production efficiency. The air-blowing ejection mechanism includes an air pump installed at the bottom of the lower mold, with a venting groove inside the lower mold communicating with the steel needle insertion hole. After the silicone nipple completes microporous molding, the airflow generated by the air pump is ejected through the venting groove and the steel needle insertion hole, quickly ejecting the molded nipple from the molding cavity without manual removal, thus speeding up the production process.

[0027] Easy to maintain and use:

[0028] The steel needle grouping design allows for individual replacement of the corresponding group of steel needles when some needles become worn or damaged, reducing maintenance costs and time.

[0029] The non-contact ejection method of the air-blowing ejection mechanism will not leave marks on the nipple, ensuring the product's appearance quality. At the same time, it can also remove impurities inside the steel needle insertion hole during the ejection process, achieving multiple benefits. Attached Figure Description

[0041] Example 1

[0042] like Figures 1 to 5 The present invention provides a multi-hole punch device for micro-hole molding of silicone nipples, including a base 100, a top plate 120 fixedly installed on the top of the base 100 by a bracket 110, a cylinder 200 installed at the bottom center of the top plate 120 by bolts, a movable plate 210 installed at the lower end of the piston rod of the cylinder 200 by bolts, and a plurality of punching components installed at the bottom of the movable plate 210.

[0043] Each punching assembly includes a round rod 300 and several steel needles 340. The upper end of the round rod 300 movably passes through the movable plate 210. An anti-detachment plate 310 is installed on the top of the round rod 300, located above the movable plate 210. The anti-detachment plate 310 prevents the round rod 300 from detaching from the movable plate 210. The top outer wall of the round rod 300 has external threads, and the bottom center of the anti-detachment plate 310 has a threaded hole 311. The top of the round rod 300 is screwed into the inside of the threaded hole 311. A core 320 is fixedly installed at the lower end of the round rod 300. A spring 330 is fitted around the outside of the round rod 300, located between the movable plate 210 and the core 320. The spring 330 is located between the moving plate 210 and the core 320. During the stamping process, the spring 330 first causes the core 320 to gradually increase the pressure on the silicone nipple 421. This buffering effect can prevent the steel needle 340 from directly impacting the silicone nipple 421 excessively, preventing problems such as tearing and deformation of the nipple material, and improving the product qualification rate. The lower end of the steel needle 340 moves through the core 320 and extends to the bottom of the core 320. With the round rod 300 as the dividing point, the steel needle 340 is divided into left and right groups. The top of the steel needle 340 in both groups is fixedly installed with a connecting block 341, which makes the steel needle 340 more evenly stressed during the stamping process and ensures the consistency of the forming of each microhole. Moreover, this grouping design facilitates the replacement and maintenance of the steel needle 340. When some steel needles 340 are worn or damaged, the corresponding group of steel needles 340 can be replaced individually, reducing maintenance costs and maintenance time.

[0044] The base 100 is fixedly mounted on the top via a support column 410. The lower mold 400 has a molding cavity 420 that corresponds one-to-one with the core 320 for placing the silicone nipple 421. The lower mold 400 also has a steel needle insertion hole 430 for inserting the steel needle 340. The molding cavity 420 on the lower mold 400 corresponds one-to-one with the core 320 for placing the silicone nipple 421. This precise positioning design ensures that the silicone nipple 421 is accurately positioned during the stamping process, allowing the steel needle 340 to punch micro-holes in the nipple according to the preset position and shape, thereby improving the molding accuracy and quality stability of the product. Meanwhile, the design of multiple molding cavities 420 can realize the stamping of multiple silicone nipples 421 at one time, which improves production efficiency; the steel needle insertion hole 430 on the lower mold 400 provides a precise insertion channel for the steel needle 340, ensuring that the steel needle 340 can penetrate the silicone nipple 421 vertically and accurately during stamping, avoiding bending or displacement of the steel needle 340, thereby ensuring that the shape and size of the micro-hole meet the design requirements and improving the product yield.

[0045] It also includes an air-blowing ejection mechanism that lifts the silicone nipple 421. This mechanism includes an air pump 500 installed at the bottom of the lower mold 400. The lower mold 400 has a ventilation groove 440 communicating with the steel needle insertion hole 430. The air outlet of the air pump 500 is connected to the ventilation groove 440 via a pipe. After the silicone nipple 421 completes microporous molding, the airflow generated by the air pump 500 can quickly eject the molded nipple from the molding cavity 420 without manual removal. This not only improves production efficiency but also avoids damage to the nipple that may be caused by manual operation. Furthermore, this non-contact ejection method leaves no marks on the nipple, ensuring the product's appearance quality. This design also removes impurities from inside the steel needle insertion hole 430, achieving multiple benefits.

[0046] At least two limiting rods 220 are installed at equal intervals on the top of the movable plate 210. The upper end of the limiting rod 220 moves through the top plate 120. The limiting rod 220 installed on the top of the movable plate 210 moves through the top plate 120. During the downward and upward movement of the movable plate 210, the limiting rod 220 plays a guiding and limiting role, preventing the movable plate 210 from shifting or tilting, ensuring the linearity and stability of the movement of the movable plate 210, thereby ensuring the stamping position accuracy of the steel needle 340 and the core 320 in the punching assembly, and further improving the quality of the micro-hole forming of the silicone nipple 421.

[0047] The following is the working principle of the multi-hole punch device for microporous molding of silicone nipples:

[0048] Preparation stage: Place the silicone nipple 421 into the molding cavity 420 of the lower mold 400. At this time, the air pump 500 is in the off state and the air-blowing ejection mechanism is not working.

[0049] Downward pressure phase: such as Figure 1 As shown, the cylinder 200 at the bottom of the top plate 120 is activated, causing the moving plate 210 at the lower end of the piston rod to press down. The punching assembly installed at the bottom of the moving plate 210 moves down accordingly, and the limiting rod 220 moves within the movable hole on the top plate 120, which plays a limiting role and ensures that the moving plate 210 presses down vertically.

[0050] Contact phase: The steel needle 340 in the punching assembly first contacts the silicone nipple 421, and then the core 320 also presses down on the silicone nipple 421. Since the round rod 300 is externally fitted with a spring 330 and the round rod 300 is located between the moving plate 210 and the core 320, under the action of the spring 330, the core 320 gradually increases the pressure on the silicone nipple 421, while the relative positions of the steel needle 340 and the core 320 remain unchanged.

[0051] Punching stage: such as Figure 4 and Figure 5 As shown, the moving plate 210 continues to press down until it contacts the connecting block 341, and then continues to press down the connecting block 341 and the steel needle 340, so that the steel needle 340 passes through the silicone nipple 421 and is inserted into the steel needle insertion hole 430 on the lower mold 400, thus completing the punching process of the silicone nipple 421.

[0052] Ejection Stage: After punching is completed, cylinder 200 drives moving plate 210 to rise and reset. At this time, air pump 500 starts, and air outlet of air pump 500 introduces gas into ventilation groove 440 through pipe. Ventilation groove 440 is connected to steel needle insertion hole 430. Gas is ejected from steel needle insertion hole 430, pushing the molded silicone nipple 421 out of molding cavity 420 for easy removal by operator.

[0053] Therefore, this multi-hole punch device is used for microporous molding of silicone nipples:

[0054] The structure is stable and reliable: The base 100 is fixedly mounted on the top plate 120 via the bracket 110, forming a stable frame structure that provides solid support for the cylinder 200, the moving plate 210, and the punching assembly, ensuring operational stability. At least two equidistant limiting rods 220 are installed on the top of the moving plate 210, with their upper ends moving through the top plate 120. These rods guide and limit the movement of the moving plate 210 during its downward and upward movements, preventing it from shifting or tilting, ensuring the linearity and stability of its movement, and thus guaranteeing the stamping position accuracy of the steel needle 340 and the core 320 in the punching assembly.

[0055] Improve product quality:

[0056] The top of the round rod 300 is screwed into the threaded hole 311 of the anti-detachment plate 310 through an external thread. The anti-detachment plate 310 is located above the moving plate 210 to prevent the round rod 300 from detaching from the moving plate 210.

[0057] The spring 330, which is externally mounted on the round rod 300, is located between the moving plate 210 and the core 320. During stamping, the core 320 gradually increases the pressure on the silicone nipple 421. The buffering effect prevents the steel needle 340 from causing excessive impact on the silicone nipple 421, prevents the nipple material from tearing or deforming, and improves the product qualification rate.

[0058] The steel needles 340 are divided into left and right groups by the round rod 300 as the dividing point, and the top is fixed by the connecting block 341. The connecting block 341 makes the steel needles 340 more evenly stressed during the stamping process, ensuring the consistency of the forming of each micro hole and improving product quality. On the other hand, during the punching stage, after the moving plate 210 presses down and contacts the connecting block 341, the downward pressure on the connecting block 341 pushes the steel needles 340 through the silicone nipple 421, which plays a role in transmitting pressure and ensuring the smooth progress of the punching action.

[0059] The molding cavity 420 on the lower mold 400 corresponds one-to-one with the core 320 and is used to place the silicone nipple 421. Precise positioning ensures that the silicone nipple 421 is in the correct position during stamping, so that the steel needle 340 can punch out micro-holes according to the preset position and shape, thereby improving the product molding accuracy and quality stability.

[0060] The steel needle insertion hole 430 not only provides a precise insertion channel for the steel needle 340, ensuring that the steel needle 340 penetrates the silicone nipple 421 vertically and accurately during stamping, preventing the steel needle 340 from bending or deviating, ensuring that the shape and size of the micro-hole meet the design requirements, and improving the product yield; it also connects with the ventilation groove 440 and acts as an air jet channel in the air-blowing ejection mechanism to eject the molded silicone nipple 421 from the molding cavity 420.

[0061] Improve production efficiency:

[0062] The design of multiple molding cavities 420 on the lower mold 400 allows for the stamping of multiple silicone nipples 421 in one operation, improving production efficiency.

[0063] The air-blowing ejection mechanism includes an air pump 500 installed at the bottom of the lower mold 400. The lower mold 400 has a venting groove 440 communicating with the steel needle insertion hole 430. After the silicone nipple 421 completes microporous molding, the airflow generated by the air pump 500 is ejected through the venting groove 440 and the steel needle insertion hole 430, quickly ejecting the molded nipple from the molding cavity 420 without manual removal, thus speeding up the production process.

[0064] Easy to maintain and use:

[0065] The steel needles 340 are designed in groups, so when some steel needles 340 are worn or damaged, the corresponding group of steel needles 340 can be replaced individually, which reduces maintenance costs and maintenance time.

[0066] The non-contact ejection method of the air-blowing ejection mechanism will not leave marks on the nipple, ensuring the product's appearance quality. At the same time, it can also remove impurities inside the steel needle insertion hole 430 during the ejection process, achieving multiple benefits.

[0067] High degree of automation: The cylinder 200 at the bottom of the top plate 120 can precisely control the downward stroke and pressure of the moving plate 210. Compared with other power sources, it is easier to achieve automated control, reducing the difficulty and labor intensity of manual operation.

[0068] The cylinder 200 is preferably a QGB-32-125-MP2 cylinder; the air pump 500 is preferably an RB-21D-1 air pump.

[0069] The above are merely preferred embodiments of the present utility model and are not intended to limit the implementation methods and protection scope of the present utility model. Those skilled in the art should realize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
