Description

Technical Field

[0001] This utility model relates to the field of mold replacement, specifically a mold frame that facilitates mold switching. Background Technology

[0002] A mold frame is the support for a mold. For example, on a die-casting machine, the mold frame is the part that assembles and fixes the various parts of the mold according to a certain pattern and position, allowing the mold to be installed and work on the die-casting machine. It consists of an ejection mechanism, a guiding mechanism, a pre-reset mechanism, mold foot pads, and a base plate. The mold frame is a semi-finished product of the mold, composed of various steel plates and matching parts; it can be considered the skeleton of the entire mold. Because the processing involved in mold frames and molds differs greatly, mold manufacturers often choose to order mold frames from mold frame manufacturers, leveraging the production advantages of both parties to improve overall production quality and efficiency.

[0003] In the existing technology, molds and mold frames are usually fixedly connected or connected by bolts. When replacing the mold, it is necessary to disassemble it step by step, which is inconvenient and reduces manufacturing efficiency.

[0004] Therefore, a mold frame that facilitates mold switching is proposed to address the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one of the technical problems mentioned in the background art, this utility model proposes a mold frame that facilitates mold switching.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: A mold frame for convenient mold switching, comprising a base; an electric push rod fixedly connected to the top of the base, an upper mold fixedly connected to the top of the electric push rod, a rotating seat rotatably connected to the top of the base, a motor fixedly connected to the bottom of the base, the output end of the motor fixedly connected to the rotating seat, a lower mold slidably connected to the top of the rotating seat, an mounting block fixedly connected to the top of the rotating seat, the mounting block slidably connected to the lower mold, a fixing block fixedly connected to the top of the rotating seat, and a rotatably connected component inside the fixing block. The screws are connected by a belt drive. A first limiting block is threaded onto the surface of each screw, and the first limiting block is slidably connected to a rotating seat. A connecting block is fixedly connected to the side of the lower mold, and the first limiting block is slidably connected to the connecting block. This step, by driving the rotating seat to rotate via a motor, allows adjustment of the positions of the two lower molds. While processing one lower mold, the other can be replaced without affecting the processing of the lower mold. By driving the two screws to rotate, the screws cause the first limiting blocks and connecting blocks on both sides to separate, facilitating simultaneous assembly and disassembly of the two lower molds.

[0007] Preferably, a cylinder is fixedly connected to the bottom of the base, and a second limiting block is fixedly connected to the output end of the cylinder. A limiting groove is opened inside the rotating seat, and the base and the limiting groove are slidably connected to the second limiting block. In this step, the rotating seat is provided with two limiting grooves inside. When the rotating seat rotates, the second limiting block is connected to the limiting groove to fix the angle of the rotating seat, making the rotating seat more stable after rotation.

[0008] Preferably, a protective shell is fixedly connected to the top of the rotating seat, and the protective shell is rotatably connected to the positive and negative thread screws; this step can protect the belt through the protective shell, and at the same time support the positive and negative thread screws.

[0009] Preferably, a handle is fixedly connected to the surface of the screw thread, the handle is rotatably connected to the protective shell, the side of the protective shell is provided with a bevel, and the surface of the handle is provided with an anti-slip groove; in this step, the operator can rotate the screw thread by rotating the handle, which makes it convenient for the operator to rotate the screw thread.

[0010] Preferably, a sliding rod is fixedly connected to the side of the fixed block, and the first limiting block is slidably connected to the sliding rod; in this step, the sliding rod can increase the stability of the first limiting block when it moves and support the bottom of the first limiting block.

[0011] Preferably, a limiting rod is fixedly connected to the inner side of the connecting block, and the limiting rod is slidably connected to the first limiting block; this step can increase the stability of the first limiting block when it is connected to the connecting block.

[0012] The advantages of this utility model are:

[0013] 1. The mold frame of this utility model is designed to facilitate mold switching. The position of the two lower molds can be adjusted by rotating the rotating seat driven by the motor. When processing one lower mold, the other lower mold can be replaced without affecting the processing of the lower mold. By driving the two positive and negative thread screws to rotate, the positive and negative thread screws drive the first limiting blocks on both sides to separate from the connecting blocks, which facilitates the simultaneous assembly and disassembly of the two lower molds.

[0014] 2. The mold frame for convenient mold switching described in this utility model has two limiting grooves inside the rotating seat. When the rotating seat rotates, the second limiting block connects with the limiting groove to fix the angle of the rotating seat, making the rotating seat more stable after rotation.

[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] like Figures 1 to 5As shown, a mold frame for convenient mold switching includes a base 1; an electric push rod 12 is fixedly connected to the top of the base 1, an upper mold 13 is fixedly connected to the top of the electric push rod 12, a rotating seat 14 is rotatably connected to the top of the base 1, a motor 15 is fixedly connected to the bottom of the base 1, the output end of the motor 15 is fixedly connected to the rotating seat 14, a lower mold 16 is slidably connected to the top of the rotating seat 14, a mounting block 17 is fixedly connected to the top of the rotating seat 14, the mounting block 17 is slidably connected to the lower mold 16, and a fixed... Block 18, the fixed block 18 is internally rotatably connected to a threaded screw 19, the threaded screw 19 is connected to each other via a belt drive, the surface of the threaded screw 19 is threaded to a first limiting block 110, the first limiting block 110 is slidably connected to the rotating seat 14, the side of the lower mold 16 is fixedly connected to a connecting block 111, the first limiting block 110 is slidably connected to the connecting block 111; during operation, the motor 15 drives the rotating seat 14 to rotate, the rotating seat 14 drives the structure on its top to rotate, and the electric push rod 12 drives the rotation of the rotating seat 14. The upper mold 13 moves downward to form the mold inside the lower mold 16. When one of the lower molds 16 rotates to below the upper mold 13, the other lower mold 16 rotates to the other side. When the lower mold 16 needs to be replaced, the threaded screw 19 is rotated. The threaded screw 19 drives the belt in the middle to rotate, which in turn drives the threaded screw 19 on the other side to rotate. The two threaded screws 19 drive the first limiting blocks 110 on both sides to move towards the middle, separating them from the connecting block 111. When the first limiting block 110 and the connecting block 111 are separated... When the connecting block 111 is separated, the connecting block 111 can be pulled to remove the lower mold 16 that needs to be replaced, so that it is separated from the mounting block 17. This step can adjust the position of the two lower molds 16 by rotating the rotating seat 14 driven by the motor 15. When processing one lower mold 16, the other lower mold 16 can be replaced without affecting the processing of the lower mold 16. By driving the two positive and negative thread screws 19 to rotate, the positive and negative thread screws 19 drive the first limit blocks 110 on both sides to separate from the connecting block 111, which makes it easy to disassemble and assemble the two lower molds 16 at the same time.

[0024] like Figure 4As shown, a cylinder 21 is fixedly connected to the bottom of the base 1, and a second limiting block 22 is fixedly connected to the output end of the cylinder 21. A limiting groove 23 is opened inside the rotating seat 14. The base 1 and the limiting groove 23 are slidably connected to the second limiting block 22. During operation, when the rotating seat 14 rotates, the second limiting block 22 aligns with the limiting groove 23. The cylinder 21 drives the second limiting block 22 to connect with the limiting groove 23, fixing the angle of the rotating seat 14. When the cylinder 21 drives the second limiting block 22 to separate from the limiting groove 23, the rotating seat 14 can rotate. In this step, the rotating seat 14 has two limiting grooves 23 inside. When the rotating seat 14 rotates, the second limiting block 22 connects with the limiting groove 23 to fix the angle of the rotating seat 14, making the rotating seat 14 more stable after rotation.

[0025] like Figure 4 and Figure 5 As shown, a protective shell 31 is fixedly connected to the top of the rotating seat 14, and the protective shell 31 is rotatably connected to the positive and negative thread screw 19; this step can protect the belt through the protective shell 31, and at the same time support the positive and negative thread screw 19.

[0026] like Figure 5 As shown, a handle 41 is fixedly connected to the surface of the screw 19 with both positive and negative threads. The handle 41 is rotatably connected to the protective shell 31. The protective shell 31 has a beveled opening on its side, and the surface of the handle 41 has an anti-slip groove. During operation, the screw 19 with both positive and negative threads is rotated by rotating the handle 41. This step allows the operator to rotate the screw 19 with both positive and negative threads by rotating the handle 41, making it convenient for the operator to rotate the screw 19 with both positive and negative threads.

[0027] like Figure 5 As shown, a sliding rod 51 is fixedly connected to the side of the fixed block 18, and the first limiting block 110 is slidably connected to the sliding rod 51; in this step, the sliding rod 51 can increase the stability of the first limiting block 110 when it moves and support the bottom of the first limiting block 110.

[0028] like Figure 4 As shown, a limiting rod 61 is fixedly connected to the inner side of the connecting block 111, and the limiting rod 61 is slidably connected to the first limiting block 110. During operation, when the first limiting block 110 is connected to the connecting block 111, it can also be connected to the limiting rod 61. This step can increase the stability of the first limiting block 110 when it is connected to the connecting block 111.

[0029] Working principle: The motor 15 drives the rotating seat 14 to rotate, which in turn drives the structure on top of the rotating seat 14 to rotate. The electric push rod 12 drives the upper mold 13 to move downwards, forming the mold inside the lower mold 16. When one lower mold 16 rotates to below the upper mold 13, the other lower mold 16 rotates to the other side. When the lower mold 16 needs to be replaced, the handle 41 is turned to drive the threaded screw 19 to rotate. The threaded screw 19 drives the belt in the middle to rotate, which in turn drives the threaded screw 19 on the other side to rotate. The reverse thread screw 19 drives the first limiting blocks 110 on both sides to move towards the middle, separating them from the connecting block 111 and the limiting rod 61. When the first limiting block 110 separates from the connecting block 111, the connecting block 111 can be pulled to remove the lower mold 16 that needs to be replaced, separating it from the mounting block 17. When the rotating seat 14 rotates, the second limiting block 22 aligns with the limiting groove 23. The cylinder 21 drives the second limiting block 22 to connect with the limiting groove 23, fixing the angle of the rotating seat 14. When the cylinder 21 drives the second limiting block 22 to separate from the limiting groove 23, the rotating seat 14 can rotate.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
