Technical Field

[0001] This utility model belongs to the field of mold frame technology, specifically relating to a mold frame mechanism that allows for quick mold core replacement. Background Technology

[0002] Mold base and mold core are key components in mold manufacturing. The mold base, as the basic framework of the mold, consists of fixed mold base plate, moving mold base plate, guide pillars, guide sleeves, and other parts. It supports, positions, and mounts the mold core and other mold components, providing structural stability and guiding the mold opening and closing. The mold core, on the other hand, is the core component that directly forms the product in the mold. Designed and manufactured according to the product's shape, size, and performance requirements, it works in conjunction with the mold base to fill the cavity with molten or liquid material during injection molding, die casting, and other molding processes. After cooling and solidification, it forms the desired product shape. Together, they ensure that the mold efficiently and accurately produces qualified products.

[0003] In traditional mold frame mechanisms, replacing the mold core usually requires complex disassembly tools and cumbersome operating procedures, which consumes a lot of time and manpower, seriously affecting production efficiency and making it difficult to meet the needs of modern manufacturing for efficient and flexible production. Therefore, a mold frame mechanism that can quickly replace the mold core is proposed. Utility Model Content

[0004] The purpose of this invention is to provide a mold frame mechanism that is easy to operate and allows for quick mold core replacement in order to solve the above-mentioned problems.

[0005] This utility model achieves the above objectives through the following technical solutions:

[0006] A mold frame mechanism with quick mold core replacement includes a base and an A plate disposed on the base. A guide post is fixedly disposed on the A plate, and a B plate is slidably disposed on the A plate through the guide post. Both the A plate and the B plate are provided with T-shaped grooves, and a mold core is slidably disposed in the T-shaped grooves.

[0007] It also includes:

[0008] A panel, which is fixedly mounted on the mold core;

[0009] A pull rod, which is slidably mounted on the panel;

[0010] A horizontal plate, which is connected to a tie rod, is driven to move longitudinally by the tie rod;

[0011] An embedded block is slidably disposed on both sides of the panel, and is driven to move inward by a horizontal plate.

[0012] As a further optimization of this utility model, side plates are fixed on both sides of the mold core, the side plates are connected to the panel, and a handle is fixedly provided on the panel.

[0013] As a further optimization of this utility model, the pull rod is provided with sliding rods on both sides, the sliding rods slide through the side wall of the panel, and the sliding rods are connected to the horizontal plate after passing through the side wall of the panel.

[0014] As a further optimization of this utility model, the pull rod is located inside the handle.

[0015] As a further optimization of this utility model, a connecting rod is provided between the horizontal plate and the embedded block, and the two ends of the connecting rod are respectively hinged to the horizontal plate and the embedded block. A spring is sleeved on the sliding rod, and the two ends of the spring are respectively connected to the horizontal plate and the inner wall of the panel.

[0016] As a further optimization of this utility model, the surface of the embedded block is rounded.

[0017] As a further optimization of this utility model, the inner surface of the T-shaped groove is provided with embedding holes on both sides, and the embedding block can be embedded in the embedding holes.

[0018] As a further optimization of this utility model, the side plate and the mold core form a T-shaped structure.

[0019] The beneficial effects of this utility model are as follows:

[0027] The present application will now be described in further detail with reference to the accompanying drawings. It should be noted that the following specific embodiments are only used to further illustrate the present application and should not be construed as limiting the scope of protection of the present application. Those skilled in the art can make some non-essential improvements and adjustments to the present application based on the above application content.

[0028] Example 1

[0029] like Figure 1 - Figure 5 As shown, a mold frame mechanism for quick mold core replacement includes a base 1 and an A plate 2 mounted on the base 1. A guide post 4 is fixedly mounted on the A plate 2, and a B plate 3 is slidably mounted on the A plate 2 via the guide post 4. Both the A plate 2 and the B plate 3 have T-slots 10, and a mold core 5 is slidably mounted within the T-slots 10. The base 1 serves as the basic support component of the entire mold frame mechanism, providing a stable mounting platform for the A plate 2 and ensuring the stability of the mechanism during operation. The A plate 2 and the B plate 3 form a sliding connection structure via the guide post 4, allowing the B plate 3 to slide smoothly along the guide post 4, facilitating position adjustment during mold opening and closing. The T-slots 10 on the A plate 2 and the B plate 3 provide a precise sliding track and installation positioning for the mold core 5, restricting the horizontal freedom of the mold core 5, ensuring the positional accuracy of the mold core 5 during operation, and also providing a structural basis for the quick disassembly and installation of the mold core 5.

[0030] A panel 6 is fixedly mounted on the mold core 5, and side plates 61 are fixed on both sides of the mold core 5. The side plates 61 are connected to the panel 6, and a handle 62 is fixedly mounted on the panel 6. The panel 6 serves as a support platform for the mold core 5, which not only protects the mold core 5 but also provides installation positions for other components such as the tie rod 7 and the cross plate 8. The side plates 61 and the mold core 5 form a T-shaped structure, which cooperates with the T-shaped grooves 10 on the A plate 2 and the B plate 3 to enhance the stability and guidance of the mold core 5 sliding within the T-shaped grooves 10 and prevent the mold core 5 from shifting during sliding. The handle 62 provides a convenient force application point for the operator, making it easy to push and pull the mold core 5 when changing it, reducing the difficulty of operation and improving the replacement efficiency.

[0031] A pull rod 7 is slidably mounted on the panel 6, with slide rods 71 ​​on both sides of the pull rod 7. The slide rods 71 ​​slide through the side wall of the panel 6, and the pull rod 7 is slidably mounted on the panel 6 via the slide rods 71. After passing through the side wall of the panel 6, the slide rods 71 ​​connect to the horizontal plate 8. The pull rod 7 is located inside the handle 62. The pull rod 7 is the key driving component for the entire mold core replacement operation. By pulling the pull rod 7, the operator drives the slide rods 71 ​​to slide on the side wall of the panel 6, thereby realizing the longitudinal movement of the horizontal plate 8. The slide rods 71 ​​assist the sliding of the pull rod 7 and transmit force, while limiting the direction of movement of the pull rod 7 to ensure the accuracy of the sliding trajectory of the pull rod 7. The design of the pull rod 7 being located inside the handle 62 makes reasonable use of the space layout on the panel 6, making it more convenient for the operator to operate the pull rod 7, while protecting the handle 62 to prevent accidental contact, and does not affect the normal use of the handle 62.

[0032] A horizontal plate 8 is connected to the pull rod 7, which drives the horizontal plate 8 to move longitudinally. Embedded blocks 9 are slidably mounted on both sides of the panel 6, with rounded corners. The horizontal plate 8 drives the embedded blocks 9 to move inwards. A connecting rod 81 is provided between the horizontal plate 8 and the embedded blocks 9, with both ends of the connecting rod 81 hinged to the horizontal plate 8 and the embedded blocks 9 respectively. A spring 82 is sleeved on the sliding rod 71, with both ends of the spring 82 connected to the horizontal plate 8 and the inner wall of the panel 6 respectively. Embedded holes 101 are opened on both sides of the inner surface of the T-shaped groove 10, into which the embedded blocks 9 can be embedded. The horizontal plate 8 moves longitudinally under the drive of the pull rod 7, and the force is transmitted to the embedded blocks 9 through the connecting rod 81, which is the intermediate mechanism for realizing the movement of the embedded blocks 9. The transmission components include a connecting rod 81 that hinges the horizontal plate 8 to the insert block 9, allowing the longitudinal movement of the horizontal plate 8 to be flexibly converted into the lateral movement of the insert block 9, ensuring that the insert block 9 accurately inserts into or disengages from the insert hole 101 in the T-slot 10; the rounded corners of the insert block 9 allow it to automatically retract under pressure during the installation of the mold core 5, smoothly inserting into the insert hole 101 and achieving automatic locking of the mold core 5; the spring 82 is sleeved on the slide rod 71, providing a restoring force to the horizontal plate 8 when the pull rod 7 is not operated, keeping the insert block 9 in the locked state of the mold core 5, ensuring the stability of the mold core 5 during operation.

[0033] It should be noted that the working principle of this quick-change mold core mechanism is as follows: When the mold core 5 needs to be replaced, the operator pulls the lever 7, which drives the sliding rod 71 and the horizontal plate 8, which are slidably connected to it, to move longitudinally. The horizontal plate 8 drives the insert blocks 9 on both sides of the panel 6 to retract inward through the hinged connecting rod 81, so that they disengage from the insert holes 101 in the T-slots 10 on the A plate 2 and the B plate 3. At this time, the mold core 5 can be freely slid out along the T-slots 10 through the side plates 61 fixed on both sides, and the handle 62 provides the force application point. During installation, when the mold core 5 is pushed into the T-slot 10, the rounded corner design of the insert block 9 causes the insert block 9 to be squeezed and retracted with the edge of the insertion slot 10 until the insert block 9 is embedded in the insert hole 101, thus locking and realizing quick mold core replacement.

[0034] The embodiments described above are merely examples of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
