Abstract
A cross loose core die-casting mold comprises a mold body, a first loose core sliding block and a second loose core sliding block, wherein the mold body is provided with a mold cavity, a first loose core hole and a second loose core hole, the first loose core sliding block is provided with a first loose core, and the second loose core sliding block is provided with a second loose core. The first loose core sliding block is provided with a first stepped hole. The small end of the first stepped hole communicates with the inner end of the first loose core sliding block, and the first loose core is sleeved with the first stepped hole. A first check block and a first elastic piece are arranged in the big end of the first stepped hole, wherein one end of the first check block is connected with one end of the first loose core, and the two ends of the first elastic piece press the other end of the first check block and the bottom face of the first stepped hole correspondingly. A first rotation prevention groove is formed in the lateral periphery of the first check block. The lateral periphery of the big end of the first stepped hole is provided with a first rotation prevention block, and one end of the first rotation prevention block stretches into the first rotation prevention groove. When the loose cores are inserted into the mold cavity in place, the other end of the first loose core presses the lateral periphery of the second loose core, in the die casting process, when the first loose core is lengthened under the action of high-temperature molten alloy, the first elastic piece is compressed under pressure, thus, the second loose core is prevented from shifting, and the lateral periphery of the second loose core is not prone to damage.
