Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a kettle mold. Background Technology

[0002] Currently, injection molds are widely used in industrial production as tools for manufacturing plastic products. Their main function is to give plastic products a complete structure and precise dimensions. Injection molding is a highly efficient mass production method, especially suitable for producing parts with complex shapes. Specifically, the injection molding process involves injecting molten plastic into a mold cavity under high pressure using an injection molding machine. After cooling and solidification, the molded product is obtained.

[0003] In existing injection molding technology, there are some problems that urgently need to be solved. For example, an existing kettle mold, such as... Figure 1 As shown, since the spring 203 is on the sliding part 202 inside the cavity, the oil on the spring will splash onto the product when the mold is opened, causing the product to be scrapped, affecting product quality and production efficiency. Utility Model Content

[0004] The purpose of this utility model is to provide a kettle mold to overcome the shortcomings of the existing technology and improve product quality and production efficiency.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] A kettle mold includes a fixed mold assembly and a moving mold assembly. The moving mold assembly and the fixed mold assembly complete one injection molding of the kettle by closing and opening the mold. The fixed mold assembly includes: a main body with a cavity inside, a guide strip inside the cavity, and a spring mounting cavity at a spaced interval from the cavity; a sliding member with a guide groove that mates with the guide strip, the sliding member being slidably mounted in the cavity through the engagement between the guide groove and the guide strip; and a spring elastically connected to the sliding member through a spring connecting block, the spring being disposed in the spring mounting cavity. The moving mold assembly includes a push plate with a pressure block groove that mates with the spring connecting block, the spring connecting block being slidably mounted on the pressure block groove.

[0007] Preferably, two sliding members are symmetrically arranged in the cavity, and each sliding member is connected to multiple springs. The main body is provided with multiple spring mounting cavities, and each spring is individually installed in the spring mounting cavity. Each spring is connected to the sliding member through the spring connecting block.

[0008] Preferably, the fixed mold assembly further includes a hot runner plate and a panel, wherein the hot runner plate is mounted on the main body and communicates with the main body, and the panel is mounted and fixed on the hot runner plate.

[0009] Preferably, both the spring mounting cavity and the spring are arranged at an angle.

[0010] Preferably, the sliding member is provided with two guide grooves symmetrically, and the cavity is provided with two conductive strips that respectively cooperate with different guide grooves.

[0011] Preferably, the conductive strip has two symmetrical protrusions, and the guide groove has a groove that mates with the protrusions, the groove being used for the sliding installation of the protrusions.

[0012] This utility model discloses a kettle mold, which has the following advantages: When the moving mold assembly and the fixed mold assembly separate, the push plate moves together with the moving mold assembly, and the spring connecting block slides in the pressure block groove, driving the sliding part to slide in the cavity, thereby realizing the demolding operation of the molded kettle product. This method effectively avoids the problem of oil splattering onto the product due to the spring directly acting on the cavity, improving the surface quality of the product and reducing the scrap rate.

[0020] See Figure 2 and Figure 3 This utility model provides a kettle mold. In this embodiment, a kettle mold is provided, which mainly includes a fixed mold assembly 200 and a moving mold assembly 300. The fixed mold assembly 200 consists of a main body 201, a sliding member 202, and a spring 203. The main body 201 has a cavity 2011 and a spring mounting cavity 2012. A guide strip 2013 is installed in the cavity 2011. The guide strip 2013 cooperates with the guide groove 2021 on the sliding member 202, thereby realizing the sliding installation of the sliding member 202 within the cavity 2011. Specifically, the guide groove 2021 on the sliding member 202 matches the shape of the guide strip 2013, allowing the sliding member 202 to slide stably along the guide strip 2013 within the cavity 2011. The spring 203 is installed in the spring mounting cavity 2012 and connected to the sliding member 202 through a spring connecting block 2031, thereby providing elastic support for the sliding member 202.

[0021] It should be noted that the sliding component 202 can be customized in shape and size according to the shape and size requirements of different products to achieve precise molding of kettles of various complex shapes. At the same time, in the selection of spring 203, springs with different elasticity and different materials can also be used according to actual production needs, such as stainless steel spring 203, titanium nitride coated spring 203, etc., to meet the demolding force requirements of different products and the durability requirements of the mold.

[0022] Furthermore, both the spring mounting cavity 2012 and the spring 203 are inclined. This inclined arrangement allows the spring 203 to provide elastic support while matching the movement trajectory of the slider 202, thereby more effectively utilizing the elastic effect of the spring 203 and improving the stability and accuracy of the slider 202 during sliding. The inclined spring mounting cavity 2012 and spring 203 can also be angled according to actual production needs to adapt to water bottle products of different shapes and sizes, further improving the versatility and flexibility of the mold. The inclination angle is typically selected within the range of 5°-25°, for example, 20°. In addition, the inclined spring 203 can also adopt a pre-compression design, applying a certain compression force to the spring 203 before mold installation, so that the spring 203 can function more stably during injection molding, reducing product defects caused by spring deformation or relaxation. Meanwhile, in order to ensure that the spring 203 can work normally in the tilted state, we can also optimize the structure and material of the spring 203, such as using a special shape spring 203, such as a conical spring 203, or a material with a high elastic limit, such as spring steel or stainless steel, to improve the performance and service life of the spring 203.

[0023] Next, the moving mold assembly 300 includes a push plate 301, which has a pressing groove 3011 that cooperates with the spring connecting block 2031. The spring connecting block 2031 is slidably installed in the pressing groove 3011. When the moving mold assembly 300 and the fixed mold assembly 200 are closed, the pressing groove 3011 of the push plate 301 engages with the spring connecting block 2031 of the fixed mold assembly 200, thereby fixing the sliding member 202 in a specific position within the cavity 2011, ensuring that the molten plastic can be smoothly injected and filled into the cavity 2011 to form the shape of a kettle.

[0024] After injection molding is completed, the moving mold assembly 300 separates from the fixed mold assembly 200. At this time, the push plate 301 moves together with the moving mold assembly 300, and the spring connecting block 2031 slides in the pressure block groove 3011, driving the sliding part 202 to slide in the cavity 2011, thereby realizing the demolding operation of the molded kettle product. This design can effectively avoid the problem of oil splattering onto the product that may be caused by the spring 203 acting directly in the cavity 2011, improving the surface quality of the product and reducing the scrap rate.

[0025] To further improve the stability and reliability of the mold, two sliding parts 202 are symmetrically arranged within the cavity 2011. Multiple springs 203 are connected to each sliding part 202, and multiple spring mounting cavities 2012 are correspondingly provided on the main body 201. Each spring 203 is installed individually and connected to the sliding part 202 via a spring connecting block 2031. This ensures that the sliding part 202 experiences uniform force during sliding, preventing jamming or damage due to uneven force distribution and extending the mold's service life. Furthermore, two guide grooves 2021 are symmetrically arranged on the sliding part 202, and two conductive strips 2013 are correspondingly provided within the cavity 2011. Two protrusions 2014 are symmetrically arranged on the conductive strips 2013, and grooves 2022 are formed within the guide grooves 2021 to mate with the protrusions 2014, allowing the protrusions 2014 to slide within the grooves 2022. This method enhances the stability of the fit between the slider 202 and the guide strip 2013, preventing the slider 202 from shifting or rotating during the sliding process, thereby ensuring the molding accuracy of the product.

[0026] The fixed mold assembly 200 also includes a hot runner plate 204 and a faceplate 205. The hot runner plate 204 is mounted on and communicates with the main body 201, and is used to evenly distribute the molten plastic into the cavity 2011, ensuring that the plastic can fully fill all parts of the cavity 2011. The faceplate 205 is mounted and fixed on the hot runner plate 204, serving to protect the hot runner system and seal the cavity 2011, preventing leakage of molten plastic during injection molding. Furthermore, to facilitate quick mold replacement and maintenance, a modular design can be adopted between the hot runner plate 204 and the faceplate 205, allowing for quick disassembly and assembly of various components, thereby reducing downtime and improving production efficiency.

[0027] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
