Abstract
The utility model discloses a novel mold for casting a piston, relates to a machining device and particularly belongs to a piston casting mold with a combustion chamber. The novel mold comprises an outer mold (1), a core mold (2), a pin mold (3) and a top mold (4), wherein a pouring port (6), a casting cavity and a positioning ring (5) are arranged on the outer mold; the core mold is mounted in the positioning ring matched with the core mold, the pin mold and the top mold are mounted in a cavity of the outer mold, and the novel mold is characterized in that a boss is arranged on the top mold and corresponds to the combustion chamber of the piston; an exhaust port (7) is arranged in the top mold. The novel mold disclosed by the utility model has the positive effects of reducing production cost and improving working efficiency and product quality.
Description
Technical field
The utility model relates to machinery processing apparatus, belongs to especially a kind of casting for piston mould with combustion chamber.
Background technology
Piston is the key components and parts of engine, along with the fast development of automobile industry, also increasing for the demand of piston.Mostly piston volume production is to adopt flat roof type casting both at home and abroad at present, and the method for removing defective material by machining obtains combustion chamber.This mode is not only wasted raw material, and the process time needing is longer, makes production cost high, inefficiency.
Summary of the invention
The purpose of this utility model is to provide a kind of casting for piston novel die, to reach, reduce production costs, and the object of increasing work efficiency.
Casting for piston novel die provided by the utility model, there is external mold, core, pin mould and backform, external mold is provided with sprue gate, casting cavity and centring ring, core is arranged in the centring ring being mated, pin mould and backform are arranged in the chamber of external mold, it is characterized in that, backform is provided with boss, corresponding with the combustion chamber of piston; In backform, be provided with exhaust outlet.
Backform of the present utility model is provided with boss, when carrying out casting for piston, forms the combustion chamber on piston, has reduced manufacturing procedure when saving material; In backform, be provided with up-small and down-big exhaust outlet, can discharge the air in casting cavity, avoid temperature to reduce too fast simultaneously.In sum, the utlity model has and reduce production costs, increase work efficiency and the good effect of product quality.
Accompanying drawing explanation
Accompanying drawing partly discloses the utility model specific embodiment, wherein,
Fig. 1, the utility model assembly structure schematic diagram;
Fig. 2, the utility model backform cutaway view;
Fig. 3, the utility model backform upward view.
The specific embodiment
As shown in Figure 1, casting for piston novel die provided by the utility model, has external mold 1, core 2, pin mould 3 and backform 4, and external mold is provided with sprue gate 6, casting cavity and centring ring 5, core is arranged in the centring ring being mated, and pin mould and backform are arranged in the chamber of external mold.
As shown in Figure 2, backform is provided with boss, is provided with exhaust outlet 7 in backform, and its cross section is tapered, that is, its top internal diameter is less than bottom internal diameter.
Backform of the present utility model is provided with boss, when carrying out casting for piston, forms the combustion chamber on piston, has reduced manufacturing procedure when saving material; In backform, be provided with up-small and down-big exhaust outlet, can discharge the air in casting cavity, avoid temperature to reduce too fast simultaneously.In sum, the utlity model has and reduce production costs, the good effect of increasing work efficiency and improving the quality of products.
Claims (2)
