Description

Technical Field

[0001] This utility model relates to the field of casting mold technology, and in particular to a slider-type casting mold positioning mechanism for mounting electric heating tubes. Background Technology

[0002] In the field of modern industrial manufacturing, casting technology, as a key link in forming and processing, is widely used in industries such as aerospace, automobile manufacturing, and home appliance production. With the increasing complexity of product functional requirements, many castings need to incorporate electric heating tubes to achieve heating and temperature control functions, such as the heating box of new energy vehicle batteries and the shell of constant temperature medical equipment. This places higher demands on casting equipment.

[0003] In traditional casting machines, the lack of an effective coordinating positioning mechanism during the casting process makes it easy for the heating element to shift or loosen. This results in unstable installation of the heating element inside the casting, affecting product performance and service life. In addition, the high surface temperature of the casting and mold not only poses a risk of burns to operators but also causes the mold to be in a high-temperature state for a long time, accelerating mold material fatigue and reducing mold life. To address these issues, a sliding block casting mold positioning mechanism with an embedded heating element is used. Utility Model Content

[0004] To overcome the above deficiencies, this utility model provides a slider-type mold positioning mechanism for mounting electric heating tubes, aiming to improve the problems in the prior art where insufficient positioning accuracy of electric heating tubes leads to poor product performance and safety hazards and shortened mold life caused by high temperature of the mold.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A sliding mold positioning mechanism for mounting electric heating tubes includes a fixed mold base plate, a plurality of evenly distributed guide pillars fixedly connected to the bottom of the fixed mold base plate, a plurality of evenly distributed heating tubes fixedly connected inside the fixed mold base plate, an upper mold fixedly connected to the bottom of the fixed mold base plate, side molds one abutting on the left and right sides of the bottom of the fixed mold base plate, and side molds two abutting on the front and rear sides of the bottom of the fixed mold base plate. A moving mold base plate is slidably connected to the bottom of the side molds one, and the side molds two are slidably connected to the front and rear sides of the top of the moving mold base plate. A sliding component is provided on the top of the moving mold base plate.

[0009] Two electric push rods are fixedly connected to the outer side of the second side mold. A connecting plate is fixedly connected to the top of the electric push rods. A cooling pipe is fixedly connected to the inner side of the connecting plate. Multiple evenly distributed water outlet holes are opened at the front of the outer side of the cooling pipe.

[0010] As a further description of the above technical solution:

[0011] The inner side of the second side mold is provided with a telescopic groove, and the front end of the cooling pipe is slidably connected in the telescopic groove;

[0012] As a further description of the above technical solution:

[0033] 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.

[0034] Reference Figures 1-6 A sliding mold positioning mechanism with embedded heating tubes includes a fixed mold base plate 1, which serves as the fixed foundation component of the entire mold mechanism and is used to connect to the fixed end of the injection molding machine, providing stable support for the fixed mold part. Multiple evenly distributed guide pillars 3 are fixedly connected to the bottom of the fixed mold base plate 1, serving as precise guides to ensure that the moving mold base plate 5 slides smoothly along the guide pillars 3 during the opening and closing of the moving mold and the fixed mold. Multiple evenly distributed heating tubes 4 are fixedly connected inside the fixed mold base plate 1 to preheat and maintain the temperature of the fixed mold base plate 1, ensuring the mold reaches a suitable working temperature. An upper mold 2 is fixedly connected to the bottom of the fixed mold base plate 1, forming an important part of the casting cavity. Side molds 14 abut against the left and right sides of the bottom of the fixed mold base plate 1, and the front and rear sides of the bottom of the fixed mold base plate 1... Side mold 2 17 and side mold 14 are used to form the side structure of the casting. They work together with the upper mold 2 and side mold 2 17 to construct the complex-shaped casting cavity. They also slide to separate during mold opening, making it easy to demold the casting. Side mold 2 17 has a similar function to side mold 14 and is also used to form the side structure of the casting. The side mold 2 17 on the front and rear sides works in conjunction with the side mold 14 on the left and right sides. The bottom of side mold 14 is slidably connected to the moving mold base plate 5, which is the basic load-bearing component of the moving mold. Side mold 2 17 is slidably connected to the front and rear sides of the top of the moving mold base plate 5. The top of the moving mold base plate 5 is provided with a sliding component. The sliding component is the key structure for achieving precise positioning and sliding demolding of the heating tube 10. Through the coordinated action of its components, the position of the heating tube 10 is kept stable during the casting process.

[0035] The sliding assembly includes a slider 9, whose bottom side is slidably connected to the top left side of the moving mold base plate 5. The slider 9 is the core moving component of the sliding assembly, serving as a connection and guide between the moving mold base plate 5 and the side mold 14, while also supporting and positioning the heating element 10. The top side of the slider 9 is slidably connected to the bottom of the left side mold 14. A fixed mold groove 7 is provided on the top of the moving mold base plate 5. The fixed mold groove 7 is designed to cooperate with components at the bottom of the fixed mold base plate 1, forming accurate positioning and sealing during mold closing, ensuring the integrity of the mold cavity. The heating element 10 is slidably connected to the inner side of the slider 9, and a support block 11 is fixedly connected to the outer side of the heating element 10. The support block 11 supports and fixes the heating element 10, preventing it from shifting or loosening due to vibration or pressure during the molding process. A sliding groove 8 is provided on the top left side of the moving mold base plate 5, and the slider 9 is slidably connected within the sliding groove 8. The sliding groove 8 facilitates the sliding of the slider 9. The fixed position provides initial guidance and positioning. The bottom left side of the left mold 14 has a slide groove 2 15. The top side of the slider 9 is slidably connected in the slide groove 2 15. The slide groove 2 15 provides more precise guidance and positioning for the slider 9, further enhancing the stability and accuracy of the slider 9's sliding, and ensuring the positional accuracy of the heating tube 10 during the casting process. The left and right sides of the left and right sides of the side mold 14 abut against the left and right sides of the side mold 2 17. This abutting relationship allows the side mold 14 and the side mold 2 17 to fit tightly when the mold is closed, forming a complete side cavity of the casting, ensuring the forming accuracy of the side structure of the casting. The support block 11 abuts against the top of the moving mold base plate 5.

[0036] Reference Figure 1 , Figure 4 and Figure 5 Two electric actuators 19 are fixedly connected to the outer side of the side mold 17. These actuators 19, acting as power actuators, provide precise linear thrust to drive the extension and retraction of the cooling pipes 21, enabling precise cooling of the casting and mold. A connecting plate 20 is fixedly connected to the top of each actuator 19, and the cooling pipes 21 are fixedly connected to the inner side of the connecting plate 20. The cooling pipes 21 are the core component of the cooling system, cooling the casting and mold through an internally circulating cooling medium, reducing their temperature, improving the cooling efficiency and quality of the casting, and extending the service life of the mold. The outer side of the cooling pipes 21... The part has multiple evenly distributed water outlet holes 22, which are used to spray the cooling medium in the cooling pipe 21 in the form of water mist or water flow, directly acting on the surface of the casting and mold to achieve rapid cooling. The side mold 2 17 has a telescopic groove 18 on its inner side, and the front end of the cooling pipe 21 is slidably connected in the telescopic groove 18. The telescopic groove 18 provides guidance and space for the telescopic movement of the cooling pipe 21, so that the cooling pipe 21 can slide smoothly along the telescopic groove 18 under the drive of the electric push rod 19. When cooling is needed, it extends to cool the casting and mold, and retracts when not needed to avoid interfering with the operation of other components.

[0037] Reference Figure 1 , Figures 3-6 Side mold 2 17 is fixedly connected to the outer side of a moving mold base plate 2 16. The moving mold base plate 2 16 provides an installation base for the connection between side mold 2 17 and the injection molding machine. Side mold 1 14 is fixedly connected to the outer side of a moving mold base plate 13. The moving mold base plate 13 also provides an installation connection point for side mold 14. The top of the moving mold base plate 5 has multiple evenly distributed positioning grooves 6. The positioning grooves 6 and the guide pillars 3 cooperate to achieve precise positioning. The guide pillars 3 are slidably connected in the positioning grooves 6. The bottom of the moving mold base plate 5 is equipped with a sprue sleeve 12. The sprue sleeve 12 is the entrance channel for the plastic melt to enter the mold cavity.

[0038] Working principle: When placing the heating element 10, the heating element 10 is first slid into the guide structure inside the slider 9, and its outer side is fixed by the support block 11 to ensure stability. The bottom side of the slider 9 with the heating element 10 assembled slides along the track of the first slide groove 8, which provides precise guidance for the movement of the slider 9, allowing the slider 9 to move smoothly to the predetermined position. At the same time, the top side of the slider 9 cooperates with the second slide groove 15 at the bottom of the left side mold 14 to limit the slider 9 from two directions. During the mold closing process, the first side mold 14 and the second side mold 17 slide and approach along the bottom plate 5 of the moving mold base. Under the double constraint of the first slide groove 8 and the second slide groove 15, the slider 9 drives the heating element 10 to be precisely positioned inside the cavity, ensuring that the position of the heating element 10 is fixed during the injection molding process, and finally achieving accurate embedding of it in the casting.

[0039] After injection molding is completed, the demolding stage begins. The electric push rod 19 is activated first, and the cooling pipe 21 is pushed out along the telescopic groove 18 through the connecting plate 20. The water outlet 22 on the outside of the cooling pipe 21 immediately sprays cooling medium onto the high-temperature casting and mold surface, quickly reducing its surface temperature. This operation not only eliminates the risk of burns to the operator, but also significantly alleviates the fatigue wear of the mold caused by high temperature.

[0040] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
