A kind of manufacture mold and working method applied to steam header part
Technical field
The invention belongs to the production mould technical fields of auto parts and components, are applied to steam header part more particularly, to one kind
Manufacture mold and working method.
Background technique
With the development of automobile industry and being constantly progressive for technology, people pay attention to automotive interior spare and accessory parts more and more
Manufacture.In the road for development of automobile, engine is the core component of automobile, it is that the energy of a certain form is converted to machine
The machine of tool energy, function are to be converted into thermal energy after the chemical energy of liquid or gas is passed through burning, then thermal energy is passed through expansion
It is converted into mechanical energy and external output power.Automobile engine often with cylinder number have three cylinders, four cylinders, five cylinders, six cylinders, eight cylinders, ten cylinders,
Twelve-cylinder etc., one liter of engine below of discharge capacity commonly uses three cylinders, and our automobiles used in everyday are then four cylinder engine, discharge capacity
In 1-2.5 liter.
However corresponding steam header part is needed on four cylinder engine, which facilitates the layout of tracheae to pacify
Dress avoids turning and the abrupt change of cross-section, improves the finish etc. of pipe surface so that tracheae must assure that enough circulation areas,
To reduce resistance, air flue throttling and air tubing length are rationally designed additionally by steam header part, arranges pressure stabilizing cavity volume appropriate
Deng, and reach high turn, high-power purpose.
Therefore, certain design is needed for the mold manufacture of steam header part, due to all not having inside original product
Gradient, and present product is all transformed into arc-shaped, the product manufacturing mold of arc-shaped not can be carried out smoothly de- well
Mould can not guarantee product strength if directly ejecting using past mode well during ejection, stability compared with
Difference is easy to damage product, and the product produced is inaccurate, brings certain trouble to the manufacture of product, and past
Working method is excessively cumbersome, and the product quality produced is also poor, is unable to reach the high request of existing spare and accessory parts, it is often necessary into
The multiple processing of row, therefore the higher product mold of yields and working method, become urgent problem to be solved.
