Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, and in particular to a mold frame that facilitates the replacement of mold cores. Background Technology

[0002] Mold bases are core components in industrial manufacturing (such as plastic product molding, metal die casting, and precision parts processing). Their function is to provide a stable mounting carrier and precise positioning guidance for the molding components such as the mold core and cavity, ensuring that the mold moves synchronously and runs smoothly during the opening and closing cycle, and directly determining the dimensional accuracy and surface quality of the molded products.

[0003] Currently, Chinese utility model patent with publication number CN202422803802.8 has proposed a mold frame that facilitates mold core replacement. It attempts to solve the problems of material jamming and residue caused by thermal expansion and contraction of the mold core, as well as insufficient positioning guidance when the mold is closed, through the cooperation of a limiting movable sleeve, an adjusting rod and a movable crank.

[0004] However, in actual industrial production scenarios, this existing technology still has obvious limitations: First, the output angle of the mold core is fixed, and it cannot be flexibly adjusted according to the molding requirements of different specifications of products and the space conditions for mold core assembly and disassembly, resulting in poor adaptability; Second, the mold core replacement process still requires manual assistance from staff, which not only increases labor costs, but may also cause damage to the mold core due to manual contact, or cause safety risks due to operational errors, making it difficult to meet the needs of efficient and automated production.

[0005] Therefore, there is an urgent need to design a mold frame that can flexibly adjust the angle and realize non-contact assembly and disassembly of the mold core, so as to make up for the shortcomings of the existing technology and improve the efficiency, safety and adaptability of mold core replacement. Utility Model Content

[0006] To address the aforementioned problems, this invention provides a mold frame that facilitates the replacement of mold cores.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a mold frame that facilitates mold core replacement, comprising: The base mounting frame is the basic structure for the installation and use of the device; a vertical slide rail for adjusting the angle of the mold core is slidably installed inside, and a control linear screw motor is set on both sides of the base mounting frame; The outer shell, located inside the base mounting frame, is the basic molding structure of the mold core, and a replacement adjustment frame is slidably installed inside it. A dual-axis linear motor is used to control the height of the replacement adjustment frame. Mirror screws are fixedly installed at both ends of the motor. A positioning slider is installed on the outer thread of the mirror screw. A lifting support plate is rotatably installed on the positioning slider. The other end of the lifting support plate is rotatably connected to the replacement adjustment frame. The output control board is slidably disposed inside the replacement adjustment frame and is used to push the mold core to the outside. An output linear screw motor is installed on one side to push the output control board to move.

[0008] By adopting the above technical solution, the mold frame achieves rapid mold core replacement. The base mounting frame, serving as the installation foundation for the entire device, allows for flexible adjustment of the mold core angle via internal vertical slide rails to meet different molding requirements. The control linear screw motors on both sides provide precise linear motion control. The molding shell, as the basic molding structure for the mold core, features a slidingly mounted replacement adjustment frame for convenient mold core replacement and adjustment. A dual-axis linear motor controls the height of the replacement adjustment frame via a mirror screw and positioning slider, while a lifting support plate ensures smooth lifting and lowering of the frame. The output control board slides inside the replacement adjustment frame, and through the push of the output linear screw motor, accurately outputs the mold core to the outside, thus greatly improving the efficiency and flexibility of the mold frame.

[0009] Furthermore, the base mounting frame has movable limiting grooves on both sides, and the lower end of the vertical slide rail is slidably installed inside the movable limiting grooves.

[0010] By adopting the above technical solution, the design of the sliding limit grooves on both sides of the base mounting frame and the sliding installation of the lower end of the vertical slide rail not only enhances the stability of the vertical slide rail on the base mounting frame, preventing it from shifting or shaking during operation, but also allows the vertical slide rail to move flexibly within a certain range within the sliding limit groove according to actual molding needs, further improving the mold frame's adaptability to different molding scenarios. This design effectively ensures the accuracy and reliability of the mold frame during operation, providing a solid guarantee for high-quality molding operations.

[0011] Furthermore, the control linear screw motors are respectively installed at one end of the moving limiting groove, and the lower end of the vertical slide rail is provided with a moving threaded hole that is threadedly connected to the control linear screw motors.

[0012] By adopting the above technical solution, the threaded connection design between the linear screw motor and the lower end of the vertical slide rail enables precise control of the vertical slide rail's movement within the moving limit groove. When the linear screw motor is started, its rotational motion is converted into linear movement of the vertical slide rail through the threaded connection, allowing for precise adjustment of the vertical slide rail's position within the moving limit groove according to actual molding requirements. This design not only improves the adjustment accuracy of the mold frame but also makes the entire molding process more flexible and efficient, further meeting the operational needs of different molding scenarios.

[0013] Furthermore, a rotating connecting shaft is provided at both ends of one side of the molded outer shell, and a positioning mounting ring is fixedly welded to the upper surface of one end of the movable limiting groove, and the rotating connecting shaft is rotatably installed inside the positioning mounting ring.

[0014] By adopting the above technical solution, the design of rotating connecting shafts at both ends of one side of the molding shell and positioning mounting rings on the upper surface of one end of the movable limiting groove allows the molding shell to rotate flexibly around the rotating connecting shafts. In actual molding operations, this rotational design allows for easy adjustment of the angle and position of the molding shell, thereby better adapting to molding requirements of different shapes and sizes. At the same time, the fixed welding of the positioning mounting rings ensures the stability and reliability of the rotating connecting shafts, preventing loosening or detachment during rotation, and providing a strong guarantee for the smooth progress of molding operations.

[0015] Furthermore, the other two ends of the molded outer shell are provided with linkage sliders, which are slidably installed inside the vertical slide rail.

[0016] By adopting the above technical solution, the design of sliding sliders at both ends of the other side of the molding shell sliding inside the vertical slide rail makes the molding shell more stable and smooth when adjusting its position and angle. The sliding of the sliders within the vertical slide rail can precisely control the moving distance and direction of the molding shell, further improving the adjustment accuracy and operational flexibility of the mold frame. This design also enhances the overall stability of the mold frame, ensuring the accuracy and reliability of molding operations and providing solid technical support for efficiently completing different molding tasks.

[0017] Furthermore, the bottom of the molded outer shell is provided with a lifting and storage slot, the dual-axis linear motor is embedded in the center of the lifting and storage slot, and the positioning slider is slidably disposed inside the lifting and storage slot.

[0018] By adopting the above technical solution, the bottom of the molding shell is provided with a lifting and storage slot in which a dual-axis linear motor is embedded, and the positioning slider is slidably set inside the lifting and storage slot. This design enables the molding shell to have flexible lifting and adjustment capabilities in the vertical direction. The dual-axis linear motor can provide stable and strong driving force, ensuring that the molding shell remains stable during lifting and lowering without shaking or jamming. The sliding of the positioning slider in the lifting and storage slot further precisely controls the lifting distance and position of the molding shell, allowing the mold frame to better adapt to the molding needs of different heights and depths. This design not only improves the adjustment accuracy and operational flexibility of the mold frame, but also greatly enhances its applicability and practicality, providing a strong guarantee for the completion of various complex molding tasks.

[0019] Furthermore, rotating connectors are fixedly provided on both sides of the lower surface of the replacement adjustment frame, and the upper end of the lifting support plate is rotatably connected to the rotating connectors.

[0020] By adopting the above technical solution, the rotating connecting parts on both sides of the lower surface of the replacement adjustment frame are combined with the rotating connection structure at the upper end of the lifting support plate, realizing flexible rotation between the replacement adjustment frame and the lifting support plate. This design allows the replacement adjustment frame to be angled according to actual needs, making core replacement operations more convenient and efficient, whether horizontal or at a certain tilt angle. At the same time, the stability of the rotating connecting parts ensures that the connection between the replacement adjustment frame and the lifting support plate will not loosen or fall off during rotation, further improving the safety and reliability of the mold frame during use and providing good structural support for the rapid and accurate replacement of the mold core.

[0021] Furthermore, a sealing output groove is provided on the lower side of the replacement adjustment frame, and a sealing connecting plate is integrally provided on the lower side of the output control board. The sealing connecting plate is slidably disposed inside the sealing output groove, and an output threaded hole for threaded connection with the output linear screw motor is provided at the center of the sealing connecting plate.

[0022] By adopting the above technical solution, the sealing output groove on the lower side of the replacement adjustment frame and the sealing connecting plate integrally set on the lower side of the output control board cooperate with each other. The sealing connecting plate is slidably set inside the sealing output groove. This design ensures the sealing of the connection between the two, which can effectively prevent external impurities from entering the mold frame and affecting the normal use of the mold core and the overall performance of the mold frame. At the same time, the output threaded hole at the center of the sealing connecting plate, which is threaded to the output linear screw motor, allows the output linear screw motor to accurately control the movement of the output control board, thereby realizing precise adjustment of the replacement adjustment frame. This makes the mold core replacement process more stable and reliable, and improves the working efficiency and accuracy of the mold frame.

[0023] In summary, this utility model has the following beneficial effects: 1. In this application, the operating angle of the device can be flexibly adjusted by means of the basic mounting frame, which improves the flexibility and convenience for the user to change the mold core.

[0024] 2. In this application, the output control board is used in conjunction with a dual-axis linear motor to drive the lifting and lowering of the adjustment frame, which enables contactless disassembly and assembly of the mold core and improves the mold core replacement effect.

[0027] The technical solutions in the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application.

[0028] like Figures 1-6As shown in the figure, this application discloses a mold frame that facilitates mold core replacement, including a base mounting frame 1, which is the basic structure for device installation and use; a vertical slide rail 2 for adjusting the mold core angle is slidably installed inside; a control linear screw motor 3 is respectively provided on both sides of the base mounting frame 1; a moving limit groove is opened on both sides of the base mounting frame 1, and the lower end of the vertical slide rail 2 is slidably installed inside the moving limit groove; the control linear screw motor 3 is respectively installed at one end of the moving limit groove, and the lower end of the vertical slide rail 2 is provided with a moving threaded hole that is threadedly connected to the control linear screw motor 3.

[0029] Rotary connecting shafts are provided at both ends of one side of the molded housing 4. A positioning mounting ring is fixedly welded to the upper surface of one end of the moving limiting groove, and the rotating connecting shaft is rotatably installed inside the positioning mounting ring. Linkage sliders are provided at both ends of the other side of the molded housing 4, and the linkage sliders are slidably installed inside the vertical slide rail 2.

[0030] The outer shell 4 is located inside the base mounting frame 1 and is the basic molding structure of the mold core. A replacement adjustment frame 5 is slidably installed inside the shell. The dual-axis linear motor 6 is the power source for controlling the height of the replacement adjustment frame 5. Mirror screws 7 are fixedly installed at both ends of the motor. Positioning sliders 8 are threaded onto the outer side of the mirror screws 7. A lifting support plate 9 is rotatably installed on the positioning slider 8. The other end of the lifting support plate 9 is rotatably connected to the replacement adjustment frame 5. A lifting storage slot is provided at the bottom of the plastic housing 4. The dual-axis linear motor 6 is embedded in the center of the lifting storage slot, and the positioning slider 8 is slidably disposed inside the lifting storage slot. Rotary connecting parts are fixedly installed on both sides of the lower surface of the replacement adjustment frame 5, and the upper end of the lifting support plate 9 is rotatably connected to the rotating connecting parts.

[0031] The output control board 10 is slidably disposed inside the replacement adjustment frame 5 and is used to push the mold core to the outside. An output linear screw motor 11 for pushing the output control board 10 to move is installed on one side. A sealing output groove is opened on the lower side of the replacement adjustment frame 5. A sealing connecting plate 12 is integrally disposed on the lower side of the output control board 10. The sealing connecting plate 12 is slidably disposed inside the sealing output groove, and an output threaded hole for threaded connection with the output linear screw motor 11 is opened at the center of the sealing connecting plate 12.

[0032] The working principle of the mold frame for easy mold core replacement in this embodiment is as follows: When the mold core needs to be replaced, the linear screw motor 3 is first started and controlled. The linear screw motor 3 drives the vertical slide rail 2 to move within the moving limit groove through the threaded connection, thereby adjusting the position of the vertical slide rail 2 to adapt to the mold core replacement requirements of different sizes or angles. At the same time, since the rotating connecting shaft on one side of the plastic shell 4 is rotatably installed inside the positioning mounting ring, and the linkage slider on the other side is slidably installed inside the vertical slide rail 2, the plastic shell 4 can be adjusted in a certain angle and position as the vertical slide rail 2 moves.

[0033] Next, the dual-axis linear motor 6 is started. The mirror screws 7 at both ends of the dual-axis linear motor 6 rotate, driving the positioning slider 8 to slide in the lifting and receiving slot. During the movement of the positioning slider 8, the lifting support plate 9 rotates around the rotating connector, thereby pushing the replacement adjustment frame 5 to rise or fall inside the plastic shell 4, so that the replacement adjustment frame 5 reaches the appropriate height for the mold core replacement operation.

[0034] Once the replacement adjustment frame 5 reaches the designated height, the output linear screw motor 11 is activated. The output linear screw motor 11 drives the output control plate 10 to slide within the replacement adjustment frame 5 via a threaded connection. The sealing connection plate 12 on the lower side of the output control plate 10 slides within the sealed output groove, thereby pushing the mold core located within the replacement adjustment frame 5 out to the outside through the sealed output groove, completing the mold core output replacement process. When the mold core does not need to be replaced, all components maintain a relatively stable state, ensuring that the mold frame can perform normal molding work.

All technical solutions falling within the scope of this utility model's concept are protected.
