Abstract
Disclosed is an injection mold, comprising a moving half, a fixed half and a plurality of bearing plates positioned therebetween. The moving half comprises a moving half plate and a moving half core positioned thereon. The fixed half comprises a fixed half plate and a fixed half cavity positioned thereon. The bearing plates are positioned on one of the fixed half plate and the moving half plate and a bearing surface is formed thereon. The moving half core and the fixed half cavity contact with each other partially to form an arrangement surface. With the bearing plates positioned therebetween, the bearing surface and the arrangement surface can undertake the closing mold pressure generated by an injection molding machine together for reducing the arrangement surface area. The molding is easy and cost drops to improve productivity. The closing mold balance of the entire injection mold can be preferably ensured.
