Embodiment Construction

[0027] The present application will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0028] Please see attached figure 1 to attach Figure 7 , a turbine rotary ejection die-casting mold, including a fixed template 1, a movable template 2, a base plate 8, an ejector plate 3 fixed on the base plate 8, an ejector pin 6 fixed on the ejector plate 3 and extending upward through the movable template, and the fixed template 1 is fixedly provided with a fixed mold core 101, and the movable template 2 is fixedly equipped with a movable mold core 201. The fixed mold core 101 and the movable mold core 201 are closed to form a mold cavity, and the thimble 6 passes through the movable mold core 201 and can extend into the mold cavity. Inside, the movable template 2 includes a first movable template 21 and a second movable template 22 that can slide away relatively and is connected between the first movable template and the second movable...

Abstract

The invention relates to the technical field of metal pressure-casting, in particular to a turbine rotary ejecting pressure-casting mould. The turbine rotary ejecting pressure-casting mould comprisesa fixed moulding board and movable moulding boards, wherein the movable moulding boards comprise a first movable moulding board and a second movable moulding board which can slide relatively as well as a limiting column which is connected between the first movable moulding board and the second movable moulding board to limit the first movable moulding board and the second movable moulding board from sliding; the upper end of the first movable moulding board is fixedly provided with a movable mould core; the lower end of the second movable moulding board is fixedly provided with a rotary insertring on the second movable moulding board; a first movable mould insert is fixedly arranged on the second movable moulding board; a second movable mould insert which can be rotatably limited on the second movable moulding board is arranged between the first movable mould insert and the rotary insert ring; during mould opening, the first movable moulding board can drive the rotary insert ring to move upwards, so that the second movable mould insert rotates for separating a casting formed in the mould cavity from the second movable mould insert. A product subjected by pressure-casting of the pressure-casting die can be directly used without any post-processing process, so that casting efficiency is greatly improved.

Description

【Technical field】 [0001] The present application relates to the technical field of metal die casting, and in particular to a turbine rotary ejection die casting mold. 【Background technique】 [0002] At present, most of the turbocharger valve bodies on the market use traditional sand casting or change the shape of the turbine so that it can be demoulded. The former sand casting has low efficiency, high cost, and has a large pollution to the environment. The latter changes The shape of the turbine cannot guarantee the designer's needs. [0003] The production of existing turbine rotary castings is mainly based on low-pressure casting technology. Low-pressure casting has high requirements for molds. At the same time, the alloy material produced also has certain restrictions. The alloy products produced by low-pressure casting need to go through a post-processing process to meet the requirements. , with the application of new materials, continuously compressed costs and higher ...
