Description

Technical Field

[0001] This utility model relates to the field of mold making, specifically a mold for manufacturing engine connecting rods that is easy to demold. Background Technology

[0002] Molds are tools used in industrial production to shape products. They change the shape of materials by altering their physical state and are known as the "mother of industry." They are forming tools used in industrial production processes such as injection molding, blow molding, extrusion, die casting, forging, and stamping. They mainly achieve the shaping of products by changing the physical state of the materials.

[0003] Patent CN222755986U discloses a mold that facilitates demolding. Specifically, the patent discloses a technical solution that includes "a bottom mold, a top mold above the bottom mold, a base plate fixedly connected to the lower outer surface of the bottom mold, a top plate fixedly connected to the upper outer surface of the top mold, a first lifting cylinder between the base plate and the top plate, and a molding cavity detachably connected to the middle of the bottom mold." This solution achieves the technical effect that "the molding cavity can be separated from the bottom mold during use, and the molding cavity can be raised and lowered under the drive of the second lifting cylinder. After being raised, the molding cavity can be flipped by a rotating block, facilitating the demolding and removal of the workpiece inside the molding cavity, and also facilitating cleaning of the molding cavity for subsequent injection molding."

[0004] However, since molds need to have high structural strength, rigidity, surface hardness and processing precision, which directly determine the shape and quality of the product, if holes are opened in the inner bottom wall of the lower mold or a top plate is installed, although the injection molded workpiece can be ejected, it will affect the precision of the mold structure, which will easily affect the quality of the workpiece production. Therefore, we propose a mold for manufacturing engine connecting rods that is easy to demold, in order to solve the above problems. Utility Model Content

[0014] Compared with the prior art, the beneficial effects of this utility model include:

[0015] This utility model discloses a mold for manufacturing engine connecting rods that facilitates demolding. By installing the lower mold in a rotating demolding assembly, after the workpiece has been shaped and cooled, a drive motor rotates two connecting rods and a rotating plate, causing the lower mold installed between the two rotating plates to flip over. This allows the workpiece inside the lower mold to fall due to its own weight, thus facilitating demolding. Furthermore, the precision of the lower mold is not altered during the casting or demolding process, ensuring both easy demolding and high-quality processing. Attached Figure Description

[0023] According to one embodiment of the present invention, in conjunction with the appended drawings Figure 1-4 .

[0024] A mold for manufacturing engine connecting rods that facilitates demolding includes a processing box 1. A demolding assembly 4 is mounted on the upper surface of the processing box 1. Two clamping assemblies 3 are mounted on the inner wall of the processing box 1. A storage assembly 6 is mounted on the front of the processing box 1. An injection molding assembly 2 is mounted on the upper surface of the processing box 1. A support assembly 5 is mounted on the bottom surface of the processing box 1. The injection molding assembly 2 includes a support frame 18 located on the upper surface of the processing box 1. A first electric push rod 10 is mounted on the upper surface of the support frame 18. An upper mold 9 is mounted on the output end of the first electric push rod 10. The demolding assembly 4 includes two bearings 23, both located on the upper surface of the processing box 1. On the inner wall of the toolbox 1, the inner rings of the two bearings 23 are each equipped with a connecting rod 24. One end of one of the connecting rods 24 is equipped with a drive motor 21. The ends of the two connecting rods 24 that are close to each other are each equipped with a rotating plate 20. The sides of the two rotating plates 20 that are close to each other are equipped with a support plate 12. The upper surface of the support plate 12 is equipped with a lower mold 11. The drive motor 21 drives the two connecting rods 24 and the rotating plate 20 to rotate, which can flip the lower mold 11 installed between the two rotating plates 20, so that the workpiece inside the lower mold 11 can fall due to its own weight, thereby facilitating the demolding of the workpiece.

[0025] In this embodiment, two circular grooves 25 are provided on the inner wall of the processing box 1, and circular slide plates 22 are installed on the outer surfaces of the two rotating plates 20. Each circular groove 25 is adapted to the circular slide plate 22. Under the action of mutual sliding connection between the two circular grooves 25 and the circular slide plate 22, the two rotating plates 20 can rotate more stably.

[0026] In this embodiment, both clamping components 3 include a storage slot 14, both storage slots 14 are located on the inner wall of the processing box 1, and both processing boxes 1 have two second electric push rods 13 installed on their outer surfaces. The output ends of the two sets of second electric push rods 13 are each equipped with a movable clamping plate 15. By pushing the two movable clamping plates 15 with the two second electric push rods 13, the support plate 12 can be clamped, thereby ensuring the stability of the lower mold 11.

[0027] In this embodiment, the storage component 6 includes a storage frame 16, which is located below the lower mold 11. A baffle 17 is connected to the inner wall of the storage frame 16. The baffle 17 can be installed inside the storage frame 16 and is located below the water surface of the storage frame 16, so that after the workpiece falls into the storage frame 16, it can slide through the baffle 17 to prevent the workpiece from colliding with each other.

[0028] In this embodiment, a control panel 8 is installed on the outer surface of the processing box 1. The control panel 8 is electrically connected to the device through wires. The support component 5 includes a protective frame 19 and multiple support legs 7. The protective frame 19 is located on the back of the processing box 1, and each support leg 7 is located on the bottom surface of the processing box 1. The device can be easily controlled through the control panel 8. The drive motor 21 can be supported and protected through the protective frame 19. The device can be supported through the support legs 7, ensuring the stability of the device during operation.

[0029] Working principle: This is a mold for manufacturing engine connecting rods that facilitates demolding. When using it, the operator first places the device in a suitable position and checks all the components to ensure its normal operation. Next, water or other liquid to cool the workpiece is poured into the receiving frame 16, and the receiving frame 16 is placed into the device. Then, the device is started to process the workpiece. After the workpiece is formed, the demolding component 4 in the device is activated to flip the lower mold 11, so that the workpiece in the lower mold 11 falls into the receiving frame 16. Finally, after processing is completed, the receiving frame 16 is pulled out, and the workpiece in the receiving frame 16 is taken out.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
