Technical Field

[0001] The utility model relates to the technical field of molds, in particular to a die-casting mold. Background Art

[0002] Die casting is a metal casting process that uses high pressure to apply molten metal to the inner cavity of a mold. The mold is usually made of a stronger alloy. This process is somewhat similar to injection molding.

[0003] In the prior art, there is a die-casting mold with Chinese patent number CN218532754U, which includes a cooling shell, both ends of the cooling shell are fixedly connected with a support frame, the top of the support frame is fixedly connected with a top plate, and a hydraulic cylinder is installed on the top plate. The mold can be quickly cooled by the flow of liquid in the cooling tank, thereby improving the molding speed of the product. However, the existing die-casting mold has the problem that the molded product cannot be taken out, which makes the mold inconvenient to use. Therefore, a die-casting mold is proposed.

The installation of the sliding plate 2 facilitates the sliding of the mold core 9.

[0026] In this embodiment, specifically: two springs 11 are respectively sleeved on the circumferential sides of the bottom of the two first guide rods 10, the tops of the multiple ejector pins 4 all penetrate the base plate 1, the four mold cores 9 are connected to the sliding plate 2, and a square hole corresponding to the motor 5 is opened on the upper side of the top plate 3. The opening of the square hole makes it difficult for the top plate 3 to interfere with the motor 5 when sliding.

[0027] In the present embodiment, specifically: a guide frame 13 for guiding the two guide plates 7 is fixedly installed on the peripheral side of the substrate 1, two fixing bars 12 are fixedly installed on the lower surface side of the guide frame 13, four second guide rods 14 for guiding the two guide plates 7 respectively are fixedly installed on both sides of the two fixing bars 12, and the ends of the four second guide rods 14 away from each other are all provided with limiting protrusions for limiting the guide plates 7, and the installation of the fixing bars 12 facilitates the installation of the second guide rods 14.

[0028] In this embodiment, specifically: threaded holes are provided on the two guide plates 7 for threaded cooperation with the threaded rod 6, two circular holes corresponding to the two second guide rods 14 are symmetrically provided at the bottom of both ends of the guide plate 7, and the motor 5 is fixedly mounted on the lower surface of the base plate 1. The opening of the circular holes facilitates the sliding cooperation between the guide plate 7 and the second guide rod 14.

[0030] When the utility model is working: when the mold needs to eject the molded product, the base plate 1 and the sliding plate 2 are first fixed to the mold machine, and then the mold machine is turned on. After the mold machine is turned on, the sliding plate 2 is driven to slide, and the sliding of the sliding plate 2 drives the ejector plate 3 and the ejector pin 4 to slide. During the sliding process of the ejector pin 4, the molded product is ejected. At this time, the mold ejects the molded product;

[0031] When the mold needs to take out the molded product, the motor 5 is turned on. The motor 5 drives the two threaded rods 6 to rotate. The rotation of the two threaded rods 6 drives the two guide plates 7 and the taking-out assembly 8 to slide. At this time, the two taking-out assemblies 8 slide close to each other. The two taking-out assemblies 8 slide close to each other and are located on the lower side of the molded product. At this time, the mold machine is turned on. The sliding plate 2 slides downward for a certain distance. The ejector pin 4 and the molded product slide downward for a certain distance. The molded product falls to the upper side of the taking-out assembly 8 during the sliding process. At this time, the motor 5 is turned on in the opposite direction. The two taking-out assemblies 8 slide away from each other. The two taking-out assemblies 8 take out the molded product.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of various changes or substitutions within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
