Detailed description of the invention
The utility model is further described below in conjunction with specific embodiment and accompanying drawing.
One tubular die casting die structure as described in Fig. 1-Fig. 5, it comprises movable mold 1, fixed die 2 and correspondence are located at this movable mold 1, the dynamic model seat 10 that on fixed die 2 and position is relative, cover half seat 20, this cover half seat 20 is provided with and treats the cover half chamber that die casting 15 top profile matches, described dynamic model seat 10 is provided with and treats the core 13 that die casting 15 endoporus matches, the movable mold 1 and dynamic model seat 10 of these core 13 both sides are provided with can slide in opposition arrange slide block 12, this two slide block 12 closes up to be combined into treats with described the dynamic model chamber that die casting 15 low profile matches, this dynamic model chamber, the overall die cavity of die casting 15 is treated described in cover half chamber and core 13 form, wherein, point cooling oil circuit 16 is provided with in described core 13.
The utility model is used for carrying out Die Casting to tubular die casting, its complicated surface structure being formed and treat die casting 15 that crashed by the slide block 12 in movable mold 1 and dynamic model seat 10, and form the whole die casting die cavity treating die casting 15 in conjunction with the cover half chamber on cover half seat 20, core 13, stable molding, the temperature of core 13 is controlled additionally by point cooling oil circuit 16, than traditional extrusion process, improve tubular formed product effect, decrease cold shut, and delayed mould be full of cracks generation, increase die life.
