Description

Technical Field

[0001] This utility model relates to the field of mold making technology, and in particular to an atomizing sheet forming mold and an atomizing sheet. Background Technology

[0002] The atomizing plate is one of the core components of an atomizer. The outer periphery of the atomizing plate typically needs to be encapsulated with silicone or plastic via injection molding, a process usually performed by an injection mold. The cavity of the atomizing plate is usually small, requiring a relatively small amount of plastic injection. The injection plastic needs to fill the cavity quickly and completely encapsulate the edges of the atomizing plate. Some molds on the market use venting channels to expel air from the cavity, with some of the injection plastic entering the venting channels. This design is prone to incomplete venting when the injection plastic enters the cavity at high speed and pressure, potentially resulting in air pockets. Furthermore, because this design may leave air inside the cavity, the injection plastic may not completely fill the cavity, affecting product quality.

[0003] For example, Chinese Patent Application No. CN202122652407.0 discloses a novel atomizer mold with an in-mold locking mechanism. This type of mold is used for injection molding of atomizing sheets. Air is released through venting grooves. When the injection plastic enters the cavity at high temperature, high speed, and high pressure, incomplete venting can easily occur, potentially resulting in air holes. Because air may remain in the cavity, the injection plastic may not completely fill the cavity, affecting product quality.

[0004] For example, the atomizer injection mold disclosed in Chinese patent application number CN202121697336.X is also used for injection molding the atomizing plate. Air is released through an venting groove. When the injection plastic enters the cavity at high temperature, high speed, and high pressure, incomplete venting can easily occur, potentially resulting in air pockets. Because air may remain in the cavity, the injection plastic may not completely fill the cavity, affecting product quality. Utility Model Content

[0022] To further illustrate the technical means and effects adopted by this utility model in order to achieve the intended utility model purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model is provided in conjunction with the accompanying drawings and preferred embodiments.

[0023] Example 1 Please refer to Figures 1 to 3 As shown, it illustrates the specific structure of a preferred embodiment of the present invention, which is an atomizing sheet forming mold.

[0024] The cavity can vent air through the first venting groove 12, the second venting groove 13, and the overflow groove. At the same time, the overflow groove can also eject a portion of the injection plastic. This design can completely eliminate air in the cavity, allowing the injection plastic to quickly fill the cavity, preventing air bubbles in the product in the cavity, and controlling the pressure in the cavity to prevent the injection plastic from being damaged due to excessive pressure in the cavity.

[0025] This application provides an atomizing sheet forming mold, including a front mold core 20 and a rear mold core 10 that can be closed together; the rear mold core 10 is provided with a first cavity 11, a flow channel 110, a first venting groove 12, a second venting groove 13, a first overflow groove 14, and a first core 15; the flow channel 110, the first venting groove 12, the second venting groove 13, and the first overflow groove 14 are connected to the first cavity 11; the first core 15 is disposed in the first cavity 11; the first venting groove 12 communicates with a first slag-filling groove 19; the second venting groove 13 communicates with the first overflow groove 14; the front mold core 20 is provided with an injection hole 2. 1. A second cavity 22, a second core 23, a second slag-filling groove 24, and a second overflow groove 25; the second core 23 is disposed within the second cavity 22; the second slag-filling groove 24 and the second overflow groove 25 are connected; after the front mold core 20 and the rear mold core 10 are closed, the first cavity 11 and the second cavity 22 are closed together to form cavity 113; the first core 15 and the second core 23 press down on the atomizing sheet in the cavity; the injection hole 21 is connected to the cavity 113 through the runner 110; the second venting groove 13 is closed together with the second slag-filling groove 24; the first overflow groove 14 and the second overflow groove 25 are closed together. The front mold core 20 and the rear mold core 10 are mounted on the injection molding machine. The semi-finished atomizing sheet is placed in the first cavity 11, and the first core 15 supports the semi-finished product. When the front mold core 20 and the rear mold core 10 are closed, the injected plastic enters the cavity 113 from the injection hole 21 through the runner 110. During this process, the first venting groove 12, the second venting groove 13, the first overflow groove 14, and the second overflow groove 25 can all vent simultaneously, ensuring that the gas in the cavity 113 is quickly discharged. Simultaneously, the first overflow groove 14 and the second overflow groove 25 close to form an overflow groove, from which some of the injection molding material can be ejected. This design further ensures that the cavity 113 is completely filled with injection molding material, helping to guarantee product quality. During injection molding, a portion of the injection molding material enters the first slag pocket groove 19 to form the first slag pocket; a portion enters the second slag pocket 114 to form the second slag pocket 114; and a portion enters the overflow groove to form the third slag pocket 115. This design effectively empties the air from the cavity 113 and effectively controls the pressure within the cavity 113, preventing the injection molding material from being damaged due to excessive pressure within the cavity 113.

[0026] Preferably, the first core 15 is embedded in the first end of the first insert 16; the second end of the first insert 16 is provided with a first anti-rotation part; the second core 23 is embedded in the first end of the second insert 26; the second end of the second insert 26 is provided with a second anti-rotation part. The first and second anti-rotation parts can be easily installed and prevent rotation.

[0027] Preferably, the flow channel 110 is provided with a collecting hole 111 directly opposite the injection hole 21; the end of the flow channel 110 is provided with an upward-sloping surface 112; the molding material in the flow channel 110 enters the cavity 113 through the slope 112. The depth of the collecting hole 111 is greater than that of the flow channel 110. The injection molding material is first injected from the injection hole 21 into the collecting hole 111, and then enters the cavity 113 through the flow channel 110 and the slope 112. This design helps to expel air from the flow channel 110, and at the same time, it allows the injection molding material to be drawn into the cavity 113 at a relatively gentle speed, which is conducive to the molding of the product. When the injection molding material enters the cavity 113 from the flow channel 110, it will wrap around the edge of the atomizer semi-finished product in two paths. After the injection molding material cools and solidifies, the product is then removed. In this process, the injection molding material is divided into two channels in the cavity 113. The overflow channel, the first venting channel 12, and the second venting channel 13 work together to vent the material, ensuring product quality.

[0028] Preferably, the flow channel 110 and the first venting groove 12 are located on the midpoint line of the first cavity 11. The second venting groove 13 is located between the overflow groove and the first venting groove 12. When the injection plastic enters the cavity 113, the first venting groove 12 and the second venting groove 13 vent the plastic, and the overflow groove discharges a portion of the injection plastic, completely emptying the air in the cavity 113. That is, a portion of the injection plastic from both paths will eventually converge and be discharged from the overflow groove, ensuring better quality.

[0029] Preferably, the included angle between the second exhaust groove 13 and the first overflow groove 14 is between 30 and 15 degrees. Specifically, the included angle A can be any value among 15°, 20°, 25°, and 30°. This included angle allows for smoother exhaust, and the two work together to achieve a more balanced effect.

[0030] Preferably, the second exhaust channel 13 and the first overflow channel 14 are connected in the slag collection tank 17, and the depth of the second exhaust channel 13 is less than the depth of the first overflow channel 14. The slag collection tank 17 has a greater depth, specifically, it can be a cubic structure. The slag collection tank 17 can collect waste slag. The second and third slag bags will enter the slag collection tank 17. This design helps to reuse the waste slag and improve resource utilization.

[0031] Preferably, ejector pins are provided within the flow channel 110, the first venting groove 12, the second venting groove 13, and the first overflow groove 14; cooling pipes 18 are threaded through the front mold core 20 and the rear mold core 10, and a nitrogen spring is provided on the rear mold core 10, allowing the front mold core 20 to be pressed against the nitrogen spring. The ejector pins are used to eject the finished product and slag bag, facilitating demolding. Cooling medium flows through the cooling pipes 18, cooling the product and accelerating the molding efficiency. The nitrogen spring provides cushioning, protecting the mold and preventing damage during mold closing.

[0032] Preferably, the first core 15 and the second core 23 are components made of elastic plastic or elastic rubber. The first core 15 and the second core 23 have a certain degree of elasticity, which can prevent damage to the semi-finished product. The first core 15 and the second core 23 are made of high-temperature resistant elastic plastic or elastic rubber. This design ensures that the semi-finished product is well protected and will not be damaged when pressed by the first core 15 and the second core 23.

[0033] Preferably, a spring rod 27 is provided inside the second insert 26, and the second core 23 is embedded in the spring rod 27. The spring rod 27 can be installed in the second insert 26 by press-fitting, screws, pins, or other means. The second core 23 is embedded in the spring rod 27, so the second core 23 can gently press the semi-finished product on the first core 15. This design can prevent product displacement and improve stability.

[0034] Example 2 Please refer to Figure 4 As shown, this application provides an atomizing sheet 30, which is manufactured using an atomizing sheet 30 molding die according to Embodiment 1. The atomizing sheet 30 includes a vibrating metal sheet 31 and a piezoelectric ceramic ring 32, which are stacked together. A microporous mesh 33 is formed in the middle of the vibrating metal sheet 31, and silicone sealant covers the outer periphery of the atomizing sheet 30. The atomizing sheet 30, manufactured using an atomizing sheet 30 molding die, has better durability, better overall integrity, and guaranteed quality.

[0035] In summary, the key design feature of this utility model is that during the process of filling the cavity 113 with injection plastic, the first venting groove 12, the second venting groove 13, the first overflow groove 14, and the second overflow groove 25 can all vent simultaneously, and at the same time, part of the injection plastic can be ejected from the overflow groove. This design allows the injection plastic to quickly and completely fill the cavity 113, which helps to ensure product quality.
