Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a die-casting mold for the support bracket on the hinge of a laptop panel. Background Technology

[0002] Die casting, also known as pressure casting, is an important metal forming process widely used in modern manufacturing. The core principle of die casting is to rapidly fill a mold cavity with liquid or semi-liquid metal under high pressure and then quickly solidify it. The hinge on a laptop computer panel is made using die casting. In the die casting process, the die casting mold is the decisive factor in determining the shape and size of the hinge. However, most existing die casting molds solidify by allowing them to cool, which is a slow solidification method. This method can easily cause shape changes during mold movement, affecting product quality. Furthermore, once solidified, it is inconvenient for users to remove the product. Therefore, this utility model is proposed. Utility Model Content

Then, the upper mold box and the upper mold are installed on the lower mold box and the lower mold. Liquid metal is injected between the lower mold and the upper mold through the feed hole. The cooling component then accelerates the solidification process. After solidification, the upper mold box and the upper mold are removed, and the product is ejected by the ejector component, completing the die casting of the bracket.

[0005] Preferably, to prevent misalignment between the upper mold and the lower mold, an active limiting ring is fixedly installed on the lower outer side of the upper mold box, and limiting posts are fixedly installed at the four corners of the lower end of the active limiting ring. A passive limiting ring is fixedly installed on the upper outer side of the lower mold box, and limiting holes are provided at the four corners of the passive limiting ring, with the limiting holes cooperating with the limiting posts.

[0006] Preferably, in order to accelerate the cooling efficiency, the cooling assembly includes a cooling box, which is fixedly installed inside the lower mold box, and the upper end of the cooling box is matched with the lower end of the lower mold. A connecting pipe is fixedly installed at one end of each side of the cooling box, and one end of the connecting pipe extends to the outside of the lower mold box.

[0007] Preferably, in order to place the lower mold box at the location of use, an anti-slip pad is fixedly installed at the lower end of the lower mold box, and sliding grooves are provided at the middle positions of the four sides of the lower mold box.

[0008] Preferably, in order to install the pop-out component on the lower mold box, the pop-out component includes a hydraulic telescopic rod, which is fixedly installed at the middle position of the four sides of the lower end of the passive limiting ring.

[0009] Preferably, in order to eject the product and make it easier for the user to remove the product, the ejection assembly further includes a lifting plate, which is slidably engaged inside the lower mold box, and ejection rods are uniformly fixedly installed on the upper end of the lifting plate, with the upper end of the ejection rods extending to the upper end of the lower mold.

[0010] Preferably, in order to drive the lifting plate to rise and fall, connecting rods are fixedly installed on all four sides of the lifting plate. The connecting rods are slidably engaged in the sliding groove, and the upper end of the connecting rod is fixedly connected to the lower end of the hydraulic telescopic rod.

[0011] The beneficial effects of this utility model are: by setting a cooling component below the lower mold, the cooling of the product inside the upper and lower molds can be accelerated, thereby improving production efficiency. At the same time, after solidification, the product inside the lower mold can be ejected by the ejector component, making it convenient for users to remove the product. Attached Figure Description
