Description

Technical Field

[0001] The utility model relates to the technical field of mold frames, in particular to a mold frame capable of quickly changing molds. Background Art

[0002] The die frame is the support of the mold. For example, the part that combines and fixes the various parts of the mold according to a certain rule and position on the die-casting machine and enables the mold to be installed on the die-casting machine for work is called the die frame. It consists of an ejection mechanism, a guide mechanism, a pre-reset mechanism, a die foot pad, and a seat plate.

[0003] Chinese patent publication number CN218838310U discloses a mold frame, including a fixed mold plate, a movable mold plate and four guide pillars constituting the mold frame, the fixed mold plate is provided with concave cavities symmetrically distributed on both sides of the center line of the fixed mold plate, and a clamping claw that swings through a pin is provided in the concave cavity, and the two short axis sides of the fixed mold plate are provided with a first assembly base surface, and a locking unit with a preset shape and retractable under compression is provided on the first assembly base surface, and the locking unit is always maintained on the first assembly base surface; the clamping claw has a second assembly base surface, and a locking unit is provided on the second assembly base surface to allow the locking unit to rebound to the preset shape after the locking unit reaches the predetermined shape. A locking node is designed in a shape and combined with the locking unit, and the locking node and the concave cavity are interconnected. Although the mold frame can solve the problem of the possibility of losing the locking unit by keeping the locking unit that limits the rotation of the claw on the first assembly base surface, and it is also convenient to use, that is, the locking unit can be squeezed and retracted to complete the unlocking, and similarly, the locking can be completed when it is released and retracted, which is convenient and fast. However, common mold frames are usually fixed with bolts when installing the mold base. When the mold base is replaced, multiple sets of bolts need to be removed. The replacement steps are relatively cumbersome and it is not convenient to remove the mold base, so it needs to be improved. Utility Model Content

[0004] The purpose of the utility model is to solve the technical problems raised in the above background technology.

[0005] The utility model adopts the following technical scheme: a mold frame capable of quickly changing molds, comprising a bottom plate, a pillar being fixedly mounted on the top surface of the bottom plate, a top plate being fixedly mounted on the top surface of the pillar, a slide groove being provided on the top surface of the bottom plate, a long rod being provided inside the slide groove, a thread A being provided on one end of the long rod, a thread B being provided on the other end of the long rod, a slider being provided on the surface of the long rod, a limiting plate being fixedly mounted on the top surface of the slider, and a mold base being provided on the top surface of the bottom plate.

[0006] Preferably, a rotating disk is fixedly mounted on one end of the long rod near the thread B, a rotating rod is fixedly mounted on the surface of the rotating disk, and an adjusting block is fixedly mounted on the side of the rotating disk. Here, the long rod can be easily rotated.

[0007] Preferably, there are two groups of the sliders, and threads are provided inside the two groups of the sliders, so that the threads A and B can drive the sliders to move.

[0008] Preferably, the threads of one group of the sliders are meshed with the threads A, and the threads of the other group of the sliders are meshed with the threads B, and the threads A and B are opposite threads. Here, the threads A and B can drive the two groups of sliders to move toward each other.

Here, it is convenient to drive the abutment block to reset when the tension spring is restored.

[0011] Preferably, the clamping plates are in an "L" shape, and there are two groups of clamping plates, which are symmetrically distributed on the surface of the bottom plate. Here, it is convenient to clamp the mold base.

[0012] Compared with the prior art, the advantages and positive effects of the utility model are:

[0013] 1. In the utility model, when in use, the mold base can be fixed on the top surface of the bottom plate. When the mold base needs to be replaced, the rotating rod is manually rotated, the rotating rod drives the rotating disk to move, the rotating disk drives the long rod to move, and the long rod immediately drives the thread A and the thread B to rotate. Since the two sets of sliders are respectively engaged with the thread A and the thread B, the sliders move toward each other on the surface of the long rod, and the sliders drive the limit plates to move until the limit plates are separated from the surface of the mold base. At this time, the mold base can be released from the restriction and the mold base can be removed. In the utility model, by arranging the long rod, the slider, the limit plate, the rotating disk, the thread A and the thread B, it is convenient to limit the mold base. Only the rotating disk needs to be rotated to adjust the spacing between the limit plates, so as to clamp the mold base, which is convenient and quick to replace the mold base. At the same time, an adjusting block and a rotating rod are also provided. The rotating rod can quickly rotate the rotating disk, and the adjusting block can improve the accuracy of the rotation of the rotating disk, thereby avoiding the misalignment and offset caused by a small gap between the limit plate and the mold base, which is practical.

[0014] 2. In the utility model, when the mold base is removed, the resist block is pulled outward, and the resist block drives the tension spring and the slide bar to move outward, and the slide bar drives the clamping plate to move. At this time, the mold base is released from the restriction and can be detached from the top surface of the bottom plate. By arranging the resist block, the tension spring, the slide bar and the clamping plate, it is convenient to further fix the mold base, so that the bottom plate can fix mold bases of different sizes, which improves the adaptability and facilitates the removal and installation of the resist block. When installing, it is only necessary to resist the mold base and the clamping plate. When disassembling, it is only necessary to pull the resist block outward. The operation is simple and quick.

At this time, the die base 10 can be fixed on the top surface of the bottom plate 1. When the die base 10 is removed, the block 18 is pulled outward, and the block 18 drives the tension spring 16 and the slide bar 15 to move outward. The slide bar 15 drives the clamping plate 17 to move. At this time, the die base 10 is released from the restriction and can be separated from the top surface of the bottom plate 1. When the die base 10 is installed, the surface of the die base 10 is abutted against the clamping plate 17, and the clamping plate 17 is squeezed. The clamping plate 17 is brought The movable slide bar 15 moves outward, and the slide bar 15 then drives the stop block 18 to move outward. At this time, the stop block 18 drives the tension spring 16 to move until the mold base 10 is completely placed on the top surface of the bottom plate 1. At this time, the tension spring 16 loses external force, and due to its own tension, it drives the stop block 18 to move inward. At the same time, the stop block 18 drives the slide bar 15 to move inward, and the slide bar 15 further pushes the clamping plate 17 to move inward until the clamping plate 17 is tightly attached to the surface of the mold base 10. At this time, the clamping plate 17 can clamp and fix the mold base 10.
