Description

Technical Field

[0001] The utility model relates to the technical field of mold frames, in particular to an adjustable quick-locking mold frame. Background Art

[0002] The mold frame is a semi-finished product of the mold, composed of various steel plates and matching parts. It is the skeleton of the entire mold. The mold frame is usually a device used to support and fix the mold core. It is mainly used for fixing and supporting during the manufacture and processing of the mold, and can be easily processed.

[0003] Existing related technologies often have the following defects: when a mold core is needed for injection molding production, since the existing mold frame size is relatively fixed, a mold frame with a matching size needs to be customized for use. Customized mold frames with matching sizes can only be used for the production of products of specific sizes. If demand changes or products are updated, these mold frames may be discarded, resulting in a waste of resources.

[0004] Therefore, the utility model provides an adjustable quick-locking mold frame. Utility Model Content

[0015] The effect achieved by the above components is: by setting a locking structure, it is easy to lock the lower mold and the upper mold together, thereby avoiding the situation where the upper mold and the lower mold are disconnected due to shaking when the mold frame is moved, thereby improving the safety when the mold frame is moved.

[0016] Preferably, a latch is slidably penetrated through the surface of the base, and two round holes are provided on the surface of the rectangular rod, and the size of the latch matches the size of the round holes.

[0017] The effect achieved by the above components is that the latch is inserted into the round hole and reaches the position of limiting the rectangular rod, thereby further improving the stability of locking the lower mold and the upper mold.

[0018] Preferably, the arc surface of the latch is sleeved with a spring, and two ends of the spring are fixedly connected to the latch and the base respectively.

By providing the limiting structure 6, it is convenient to limit the mold cores 5 of different sizes in the mold cavity 4, thereby avoiding the need to customize the mold frame of the same size for use when replacing the mold core 5, thereby improving the practicality of the mold frame and reducing the discard rate of the mold frame. The surface of the bottom mold 2 is provided with a locking structure 7, and by providing the locking structure 7, it is convenient to lock the bottom mold 2 and the upper mold 3 together, thereby avoiding the situation where the upper mold 3 and the bottom mold 2 are disconnected due to shaking when the mold frame is moved, thereby improving the safety when the mold frame is moved.

[0030] The specific arrangement and function of the limiting structure 6 and the locking structure 7 will be described in detail below.

[0031] Reference Figure 2 and Figure 3 and Figure 4 As shown, in this embodiment: the two limiting structures 6 each include two threaded rods 61, which are rotatably connected to the two sides of the lower mold 2 and the upper mold 3 respectively, and the surface of the threaded rod 61 is threadedly connected to a driving arm 62, and one side of the driving arm 62 is fixedly connected to a round rod 63, and the inner wall of the mold cavity 4 is slidably connected to two clamping blocks 64, and the clamping blocks 64 are fixedly connected to one end of the round rod 63. A rectangular groove 67 is provided on the side of the two clamping blocks 64 close to each other, and the mold core 5 will slide along the inner wall of the trapezoidal groove provided on the surface of the clamping blocks 64, and the trapezoidal groove is convenient for the clamping blocks 64 to squeeze the mold core 5 in the center position of the mold cavity 4, thereby facilitating the clamping of the mold core 5. A driving rod 65 is threaded through the surface of the round rod 63, and the end of the driving rod 65 close to the mold core 5 is rotatably connected to a rectangular block 66. Rectangular grooves 67 are provided on both sides of the mold core 5. The size of the rectangular grooves 67 is adapted to the size of the mold core 5. The rotation of the driving rod 65 will move inside the round rod 63 with the help of the thread. The movement of the driving rod 65 will drive the rectangular block 66 to move toward the mold core 5. When the rectangular block 66 moves to a suitable position, the rectangular block 66 will slide into the rectangular groove 67. The rectangular block 66 reaches a position that further limits the mold core 5, thereby further improving the effect of limiting the mold core 5. Two slide grooves 68 are provided at one end of the round rod 63, and the inner walls of the two slide grooves 68 are slidably connected to the limit bars 69, and the two limit bars 69 are fixedly connected to the surface of the rectangular block 66. When the rectangular block 66 moves, it will drive the limit bars 69 to slide along the inner walls of the slide grooves 68. The slide grooves 68 limit the moving path of the limit bars 69, and then limit the moving path of the rectangular block 66, thereby preventing the rectangular block 66 from rotating when moving.

[0032] Reference Figure 5As shown, specifically, the locking structure 7 includes two bases 71, which are fixedly connected to the two sides of the lower mold 2 respectively, and a rectangular rod 72 is slidably penetrated on the surface of the base 71, and a connecting arm 73 is fixedly connected to both sides of the upper mold 3, and a rectangular hole 74 is provided on the surface of the connecting arm 73, and the size of the rectangular hole 74 is adapted to the size of the rectangular rod 72. A latch 75 is slidably penetrated on the surface of the base 71, and two round holes 76 are provided on the surface of the rectangular rod 72, and the size of the latch 75 is adapted to the size of the round hole 76. The latch 75 is inserted into the round hole 76, and the latch 75 reaches the position of limiting the rectangular rod 72, thereby further improving the stability of locking the lower mold 2 and the upper mold 3. The arc surface of the latch 75 is covered with a spring 77, and the two ends of the spring 77 are fixedly connected to the latch 75 and the base 71 respectively. The latch 75 will be inserted into the circular hole 76 with the help of the contraction force of the spring 77. The spring 77 improves the stability of the latch 75 inserted into the circular hole 76 to prevent the latch 75 from falling out of the circular hole 76 due to shaking.

[0033] Working principle: when the mold core 5 needs to be installed, first put the mold core 5 into the film cavity, and then rotate the two threaded rods 61 at the same time. The rotation of the threaded rod 61 will drive the driving arm 62 to move with the help of the thread, and the movement of the driving arm 62 will drive the round rod 63 to move, and the movement of the round rod 63 will drive the clamping block 64 to move in the direction close to the mold core 5. When the clamping block 64 moves to a suitable position, the mold core 5 is squeezed, and the mold core 5 moves with the help of the squeezing of the clamping block 64. The mold core 5 slides along the inner wall of the trapezoidal groove on the surface of the clamping block 64. When the mold core 5 moves to the center position of the mold cavity 4, the position of the mold core 5 is restricted, and the rotation of the driving rod 61 is The movable rod 65 and the driving rod 65 rotate to move in the round rod 63 with the help of the thread. The movement of the driving rod 65 drives the rectangular block 66 to move in the direction close to the mold core 5. When the rectangular block 66 moves, it drives the limit bar 69 to slide along the inner wall of the slide groove 68. The slide groove 68 limits the moving path of the limit bar 69, and then limits the moving path of the rectangular block 66, thereby avoiding the rectangular block 66 from rotating when moving. When the rectangular block 66 moves to a suitable position, the rectangular block 66 slides into the rectangular groove 67, and the rectangular block 66 reaches a position that further limits the mold core 5, thereby further improving the effect of limiting the mold core 5.

[0034] When the lower mold 2 and the upper mold 3 need to be locked together, the latch 75 is first pulled. The latch 75 moves and slides in the base 71 and gradually comes out of the circular hole 76. The latch 75 stretches the spring 77 when it moves. At this time, the spring 77 is in a stretched state. When the latch 75 comes out of the circular hole 76, the rectangular rod 72 is pulled. The rectangular rod 72 moves and slides in the base 71. When the rectangular rod 72 moves to a suitable position, the upper mold 3 is placed on the surface of the lower mold 2. The upper mold 3 drives the connecting arm 73 Slide into the base 71, and then push the rectangular rod 72 in the opposite direction. The rectangular rod 72 will slide in the base 71 and gradually insert into the rectangular hole 74. When the rectangular rod 72 moves to a suitable position, the rectangular rod 72 will pass through the rectangular hole 74, thereby limiting the position of the connecting arm 73, and then release the latch 75. The latch 75 will be inserted into the circular hole 76 with the help of the contraction force of the spring 77. The latch 75 reaches the position to limit the rectangular rod 72, thereby further improving the stability of locking the lower mold 2 and the upper mold 3.
