Abstract
The utility model relates to an integral impeller mould for the compressor impeller on the die pressing diesel engine booster belongs to mechanical parts and makes mould technical field. The blade type cavity forming machine mainly adopts the mode that a cavity insert is arranged in an outer body, a blade body cavity is arranged in the cavity insert, and a blade type cavity is arranged in the blade body cavity to form a whole. The utility model has compact and reasonable structure, low manufacturing cost and good visual effect; the molded compressor impeller profile is accurate; the relative position of each blade is accurate, and the relative blade thickness of each blade is uniform; no parting line exists between the blade tip and the blade, so that a casting flash cannot be generated, the trimming workload can be reduced, the dynamic balance performance of the impeller is good, and the efficiency of the supercharger can be improved.
Description
Technical field:
The utility model relates to a kind of monoblock type and presses impeller mold, is used for the compressor impeller on the mold pressing processing diesel engine booster, belongs to mechanical part mfg. moulding die technical field.
Technical background:
Booster is a vitals of diesel engine, is the key part in addition of these parts and press impeller.The exhaust energy that booster utilizes diesel engine to discharge changes the rotating mechanical energy drive of rotor compressor impeller into by turbine and runs up.Compressor is pressed into cylinder of diesel engine with fresh air, and the qi of chong channel ascending adversely amount of supercharged diesel engine can supply more diesel oil completing combustion.So not only can improve the power of diesel engine, also can significantly reduce the discharge of harmful substance in the waste gas, reduce the pollution of atmosphere.
Before the utility model was made, in prior art, the critical component that is used for booster on the mold pressing processing diesel engine was pressed the mould of impeller, the silicon rubber wheel mould that normally adopts assembled piece type to press impeller mold to duplicate.The compressor impeller molded lines that this kind assembled piece type mould extrudes is inaccurate; Each blade relative position inaccuracy, the leaf thickness ununiformity is even relatively; Can produce parting line between blade, form the casting peak easily, the finishing process amount is big.
Technology contents:
The purpose of this utility model is to overcome above-mentioned weak point, thereby a kind of compact conformation is provided, rationally, and low cost of manufacture; The compressor impeller of mold pressing processing has high-precision impeller profile, and each blade relative position is accurate, and leaf is thick evenly relatively; Do not have parting line between blade point, blade, the monoblock type that can not produce the casting peak is pressed impeller mold.
Main solution of the present utility model is achieved in that
It mainly adopts to be equipped with in ectosome 1 in die cavity edge body 2, the die cavity edge body 2 and is shaped on leaf build chamber 3, blade die cavity 4 is housed in the leaf build chamber 3 forms one.
Description of drawings:
Fig. 1 is the utility model structural representation:
Fig. 2 is the utility model structure A to view:
The specific embodiment:
Embodiment during following the utility model is incited somebody to action in conjunction with the accompanying drawings is further described:
The utility model adopts stainless steel material to make, and (cover) is installed ectosome 1 in die cavity edge body 2, and die cavity is inlayed in the body 2 and is shaped on leaf build chamber 3, in the leaf build chamber 3 blade die cavity 4 is housed after, integral body of four parts molds formation.Blade die cavity 4 is the 8-16 sheet.
Compared with the prior art the utility model has the following advantages:
The utility model compact conformation, rationally, low cost of manufacture, good visual effect; The compressor impeller molded lines of mold pressing processing is accurate; Each blade relative position is accurate, and the relative leaf of blade is thick evenly; Do not have parting line between blade point, blade, can not produce the casting peak, can reduce the finishing process amount; The impeller dynamic balance performance is good, can improve the power of booster.
