Description
Technical Field
[0001] This utility model relates to the field of mold frame technology, specifically a precision mold frame with positioning function. Background Technology
[0002] In modern manufacturing, mold making is a crucial link that plays a decisive role in product quality, production efficiency, and cost control. The mold base, as the core support structure of the mold, directly affects the mold's performance and the precision of the molded products through its positioning accuracy and stability. As the manufacturing industry moves towards higher precision, higher efficiency, and automation, higher demands are being placed on the positioning capabilities of precision mold bases.
[0003] The existing technology has the following defects or problems: The existing technology, disclosed in CN219944565U, relates to a precision mold frame with positioning function, including a frame body, a frame plate at the bottom of the frame body, a groove at the center of the frame plate, a servo motor on the side wall of the frame plate, the output end of the servo motor penetrating the side wall of the frame plate and having a clamping structure at its end, the clamping structure moving within the inner wall of the groove, a symmetrical T-slot vertically located at the center of the groove, and a limiting structure within the T-slot to prevent the mold from shifting position during movement. The mold is located at the center of the frame plate. This invention places the mold on the surface of the frame plate, and the limiting plate, under the action of an elastic element, presses and limits the mold, placing it at the center of the frame plate. The output end of the servo motor drives a lead screw to rotate, and clamping plates on the surface of the lead screw move relative to it. When the mold is not at the center of the frame plate, the relative movement of the clamping plates pushes the mold, causing it to quickly move to the center of the frame plate, thus improving positioning efficiency.
[0004] The aforementioned equipment lacks a precise fine-tuning mechanism for the mold's posture and position during use. When the mold shape is irregular or the placement angle is off, it is difficult to ensure that the mold can be accurately centered on the support plate, failing to meet the requirements for high-precision mold positioning. However, in existing technologies, some precision mold frames with positioning functions lack an effective locking mechanism. When the mold is running at high speed or under great pressure, the mold frame is prone to displacement, which not only reduces the service life of the mold but also poses safety hazards.
[0005] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content
[0006] To address the shortcomings of existing technologies, this utility model provides a precision mold frame with positioning function, which solves the current problems.
[0007] To achieve the above objectives, this utility model provides the following technical solution: a precision mold frame with positioning function, comprising two external plates, a guide rail fixedly connected to one side of the two external plates, a sliding groove provided at the top of the guide rail, a support plate fixedly connected to the right side of the right external plate, a motor fixedly connected to the top of the support plate, a threaded rod fixedly connected to the drive end of the motor, two sliders threadedly connected to the external thread of the threaded rod, a mold frame fixedly connected to the top of the two sliders, a positioning groove provided at the top of the mold frame, a guide post fixedly connected to the top of the mold frame, and locking components respectively provided inside the front and rear sides of the mold frame.
[0008] As a preferred embodiment of the present invention, the two locking components include a mold frame, and the front and rear sides of the mold frame are respectively provided with receiving cavities.

[0010] As a preferred embodiment of this utility model, the top ends of the two sliders are respectively fixedly connected to the bottom ends of the left and right sides of the mold frame, and the inner wall of the bottom end of the mold frame is slidably connected to the outside of the guide rail.
[0011] As a preferred embodiment of this invention, the bottom ends of the plurality of guide pillars are fixedly connected to the top of the mold frame.

[0015] 1. A precision mold base with positioning function, which is provided with a motor, threaded rod, guide rail, slide groove, slider, mold base, positioning groove, and guide post. When the motor is started, the threaded rod rotates and drives the slider to move laterally along the slide groove to adjust the horizontal position of the mold base until the positioning groove is completely aligned with the mold.

[0016] 2. A precision mold frame with positioning function, which, by setting a pull rod, a limit block, a trapezoidal locking block, and a return spring, after the mold frame is initially aligned by the guide post and the positioning groove, the trapezoidal locking block will wedge into the groove of the external equipment, the trapezoidal locking block will move with the limit block, the limit block will move with the pull rod, and at the same time, the return spring will be compressed. When the trapezoidal locking block is fully extended and locked into the groove of the external mold protrusion that it cooperates with, the return spring provides a restoring force, thereby forming a mechanical locking structure.

[0022] 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.
[0023] Example 1
[0024] Please see Figure 1-4In this embodiment: a precision mold frame with positioning function includes two outer plates 1. A guide rail 2 is fixedly connected to one side of the two outer plates 1. A slide groove 3 is opened at the top of the guide rail 2. A support plate 4 is fixedly connected to the right side of the right outer plate 1. A motor 5 is fixedly connected to the top of the support plate 4. A threaded rod 6 is fixedly connected to the drive end of the motor 5. The left and right sides of the threaded rod 6 are rotatably connected to the inner walls of the left and right sides of the guide rail 2, respectively. Two sliders 7 are threadedly connected to the outside of the threaded rod 6. The tops of the two sliders 7 are fixedly connected to the bottom ends of the left and right sides of the mold frame 8, respectively. The outside of the two sliders 7 is slidably connected to the inner wall of the slide groove 3. The tops of the two sliders 7 are fixedly connected to the mold frame 8. The bottom inner wall of the mold frame 8 is slidably connected to the outside of the guide rail 2. A positioning groove 9 is opened at the top of the mold frame 8. A guide post 10 is fixedly connected to the top of the mold frame 8. The bottom ends of multiple guide posts 10 are fixedly connected to the top of the mold frame 8. Locking components are respectively provided inside the front and rear sides of the mold frame 8.
[0025] In this embodiment, when the motor 5 starts, the drive end of the motor 5 begins to rotate, driving the threaded rod 6 to rotate synchronously. Since the threaded rod 6 and the slider 7 are connected by a thread, according to the principle of thread transmission, when the threaded rod 6 rotates, under the action of the thread, the two sliders 7 will move along the axial direction of the threaded rod 6. Because the two sliders 7 are externally slidably connected to the inner wall of the slide groove 3, the slide groove 3 restricts and guides the movement direction of the sliders 7, allowing the sliders 7 to slide smoothly within the slide groove 3 only along the direction of the guide rail 2. Simultaneously, the top ends of the two sliders 7 are fixedly connected to the bottom ends of the left and right sides of the mold frame 8, respectively. The movement of the sliders 7 will drive the mold frame 8 to move left and right along the guide rail 2, thereby achieving horizontal position adjustment of the mold frame 8. The top of the mold frame 8 has a positioning groove 9, which is used to position the parts that need to be installed on the mold frame 8 to ensure the accuracy and consistency of the parts installation. The top of the mold frame 8 is fixedly connected to the guide post 10, and its bottom end is fixedly connected to the top of the mold frame 8. The guide post 10 plays a guiding and positioning role in the mold assembly process. When other mold parts are assembled with the mold frame 8, the corresponding guide sleeves on the parts can slide along the guide post 10. Through the precise cooperation between the guide post 10 and the guide sleeve, the parts can be quickly and accurately positioned on the mold frame 8, improving the accuracy and efficiency of mold assembly. After the mold frame 8 moves to the target position, the positioning groove 9 and the guide post 10 can closely cooperate with the relevant parts to achieve precise positioning, laying the foundation for subsequent processing or molding work.
[0026] Example 2
[0027] like Figure 1 - Figure 4As shown, the two locking components include a mold frame 8. Receiving cavities 11 are respectively opened inside the front and rear sides of the mold frame 8. Pull rods 12 are slidably connected inside the two receiving cavities 11. The outer sides of the two pull rods 12 are slidably connected to the inner walls of the front and rear sides of the mold frame 8. Limiting blocks 13 are fixedly connected to the adjacent sides of the two pull rods 12. The outer sides of the two limiting blocks 13 are slidably connected to the inner walls of the two receiving cavities 11. Trapezoidal locking blocks 14 are fixedly connected to the adjacent sides of the two limiting blocks 13. The outer sides of the two trapezoidal locking blocks 14 are slidably connected to the inner walls of the mold frame 8. Return springs 15 are respectively sleeved on the outer sides of the adjacent sides of the two pull rods 12. The adjacent sides of the two return springs 15 are fixedly connected to the distant sides of the two limiting blocks 13.
[0028] In this embodiment, when the external mold component is assembled with the mold frame 8, the protrusion of the external mold will enter the positioning groove 9. At the same time, the protrusion of the external mold will contact the trapezoidal locking block 14 and push the trapezoidal locking block 14 to move. The trapezoidal locking block 14 will move with the limiting block 13, and the limiting block 13 will move with the pull rod 12. At the same time, the return spring 15 is compressed. When the trapezoidal locking block 14 is fully extended and locked into the slot of the external mold protrusion, the return spring 15 provides a restoring force, thereby forming a mechanical locking structure that firmly fixes the mold frame 8 and related components together, effectively preventing the mold frame 8 from being displaced or shaking due to external forces during mold operation, and ensuring the stability and reliability of mold operation.
[0029] The working principle and usage process of this utility model are as follows: When the motor 5 starts, the drive end of the motor 5 begins to rotate, driving the threaded rod 6 to rotate synchronously. When the threaded rod 6 rotates, the two sliders 7 will move along the axis of the threaded rod 6. The slide groove 3 restricts and guides the movement direction of the sliders 7, so that the sliders 7 can only slide smoothly in the slide groove 3 along the direction of the guide rail 2. The movement of the sliders 7 will drive the mold frame 8 to move left and right along the guide rail 2, thereby realizing the horizontal position adjustment of the mold frame 8. The positioning groove 9 is used to position the parts that need to be installed on the mold frame 8 to ensure the accuracy and consistency of the parts installation. The guide post 10 plays a guiding and positioning role in the mold assembly process. When the external mold component is assembled with the mold frame 8, the protrusion of the external mold will enter the positioning groove 9. At the same time, the protrusion of the external mold will contact the trapezoidal locking block 14 and push the trapezoidal locking block 14 to move. The trapezoidal locking block 14 will move with the limiting block 13, and the limiting block 13 will move with the pull rod 12. At the same time, the return spring 15 is compressed. When the trapezoidal locking block 14 is fully extended and locked into the groove of the external mold protrusion, the return spring 15 provides a restoring force, thereby forming a mechanical locking structure.
[0030] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the 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 this utility model should be included within the protection scope of this utility model.
