Abstract
The utility model relates to a light-weight piston mould. The light-weight piston mould comprises a base, a mould outer model which is located above the base and is used for forming a piston ring bank and a skirt section, a mould upper model which is located above the mould outer model and is used for forming a piston air valve pit and a combustion chamber, a cavity which is located in the middle of the mould outer model and is used for forming a piston inner cavity, and a mould core located in the middle of the cavity. The cavity comprises two embedding blocks which are symmetrically distributed along the axis of the mould core and are used for forming a piston window part and a light-weight part; slide blocks which are used for linking the embedding blocks are fixedly connected with the outer periphery of the mould core. The two slide blocks are symmetrically distributed at the two sides of the mould core along the axis of the mould core; the upper ends of the slide blocks are movably connected with the embedding blocks. Particularly, the upper ends of the slide blocks are clamped with the lower ends of the embedding blocks. The light-weight piston mould realizes the rapid and efficient mould closing and de-molding in a production process of light-weight pistons and the production efficiency is greatly improved.
Description
Technical field
The utility model relates to a kind of lightweight piston mould.
Background technology
Piston of gasoline engine, in new material, new technology, new technology application, starts to lightweight structure designs.At present, piston is piston skirt window place bearing capacity and light-weight design in one of application of new construction design aspect, and window place will have enough intensity, become that pressure surface is long-pending, elasticity, also will carry out herein light-weight design.The planform of lightweight piston is more complicated, has brought larger difficulty to casting for piston by the aspect such as design, processing of mould.Existing lightweight piston metal type dies complex structural designs, production efficiency is low.
Utility model content
The purpose of this utility model is to provide a kind of lightweight piston mould, and this Piston mould not only structural design is simple, can also rapidly and efficiently complete matched moulds and demoulding work in lightweight piston production process, enhances productivity.
For achieving the above object, the utility model has adopted following technical scheme: a kind of lightweight piston mould, comprise base, be positioned at base top the mould external form being shaped for piston land and skirt section, be positioned at mould external form top the mould mo(u)ld top half being shaped for piston port hole and combustion chamber, be positioned at the die cavity being shaped for piston cavity in the middle of mould external form and be positioned at the core rod in the middle of die cavity.Described die cavity comprises inserting of being shaped for piston window portion and lightweight position along core rod axis symmetrical two, is fixedly connected with and is useful on the slide block that interlock is inserted on described core rod excircle.
Described slide block is 2, and is symmetrically distributed in core rod both sides along core rod axis; Described upper end of slide block is movably connected with inserting.Specifically, described upper end of slide block and the lower end engagement connection of inserting.
From above technical scheme, the utility model, by core rod, slide block and cooperatively interacting of inserting, is first extracted core rod downwards out in the time of the demoulding, then makes slide block drive to insert to move down with core rod; In the time of matched moulds, first make core rod increase, band movable slider rising simultaneously jack-up is inserted and type, whole rear mold external form, the mould mo(u)ld top half matched moulds successively of putting in place that rise of die cavity.The utility model has been realized matched moulds rapidly and efficiently and the demoulding in lightweight piston production process, has greatly improved production efficiency.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Wherein:
1, insert, 2, slide block, 3, core rod.
Detailed description of the invention
Below in conjunction with accompanying drawing, the utility model is described further:
A kind of lightweight piston mould as shown in Figure 1, comprise base, be positioned at base top the mould external form being shaped for piston land and skirt section, be positioned at mould external form top the mould mo(u)ld top half being shaped for piston port hole and combustion chamber, be positioned at the die cavity being shaped for piston cavity in the middle of mould external form and be positioned at the core rod 3 in the middle of die cavity.Described die cavity comprise be shaped for piston window portion and lightweight position along core rod axis symmetrical two insert 1, on described core rod 3 excircles, be fixedly connected with and be useful on the slide block 2 that interlock is inserted.
Described slide block 2 is 2, and is symmetrically distributed in core rod 3 both sides along core rod 3 axis.Described slide block 2 upper ends are movably connected with 1 lower end of inserting.Specifically, described slide block 2 upper ends and the 1 lower end engagement connection of inserting.
Workflow of the present utility model is:
In lightweight piston forming process, when matched moulds, first make core rod 3 increase, core rod 3 is with movable slider 2 jack-up of rising simultaneously to insert 1 and type, die cavity rear mold external form, the mould mo(u)ld top half matched moulds successively of putting in place that all rise.In lightweight piston forming process when the demoulding, first move moulds successively mo(u)ld top half and mould external form, then extract core rod 3 downwards out, drive slide block 2 to insert 1 to move down with core rod 3, completes the demoulding.The utility model has been realized matched moulds rapidly and efficiently and the demoulding in lightweight piston production process, has greatly improved production efficiency.
Above-described embodiment is described preferred embodiment of the present utility model; not scope of the present utility model is limited; do not departing under the prerequisite of the utility model design spirit; various distortion and improvement that those of ordinary skill in the art make the technical solution of the utility model, all should fall in the definite protection domain of the utility model claims.
Claims (3)
