Description

The full aluminum cylinder mould of automobile air conditioner compressor

Technical field

Patent of the present invention is related to full aluminum cylinder die casting, and the die casting of more particularly to automobile air-conditioning compressor cylinder bodies is set Meter, belongs to precision die manufacture technology field.

Background technology：

Compressor of air conditioner is the key equipment of refrigerating system, and first generation compressor connecting rod piston formula is axle after upgrading Compressor is flowed, because drive manner is different, latter configuration is compact, smooth running vibrations are minimum during work, greatly improve machinery Efficiency.It is that, to improve stability without considering loss of weight, but car air-conditioner compresses with the weight of compressor of air conditioner in non-vehicle Machine and all parts as many need to consider energy-saving and emission-reduction and pay attention to the lightweights of parts.The aluminum cylinder car for this early development With compressor, but this aluminum cylinder compressor only refers to profile, and inner chamber still needs to be pressed into cast iron liners, so the index such as its weight is not true Positive optimization, but increases many complicated techniques.

It is not only wear-resisting but also pressure-resistant in order to realize, it can also substantially mitigate compressor of air conditioner weight, aluminum alloy compressor cylinder body is certainly It is so one of to be preferably selected, because it can bear reciprocating friction of the plunger in axial direction with compression refrigeration agent, moreover it is possible to resistance to 2.2MPa's Pressure.Research finds that the performance for only having silumin in various aluminum alloy materials can meet these requirements, and the wherein trade mark is The content of its silicon of R14 aluminium alloy reaches 18%~20%, and its anti-wear performance can greatly improved；But it is excessively common in its process Element silicon in brilliant alusil alloy is easy to precipitation and forms primary silicon, and this superhard particle brings no small to follow-up machining Harm, the expensive cutting tool of CNC machine can be scrapped when encountering primary silicon because being impacted greatly improves processing cost. The present invention makes element silicon be solid-solution in completely in aluminium, in the aluminium alloy of die casting, scooped to optimize the smelting technology of silumin Remove the precipitation that primary silicon is prevented the quick cooling of liquid aluminium alloy by mould in primary silicon, press casting procedure before pan feeding cylinder, So as to realize the purpose for removing primary silicon, be conducive to following process, reduce cost；Product is amenable to plunger in the past of axial direction simultaneously Multiple high-speed friction, cylinder body bears 2.2MPa pressure, moreover it is possible to substantially mitigate cylinder body weight, and the qualification rate of casting has reached 98%.

The content of the invention

The full aluminum cylinder mould of automobile air conditioner compressor, the full aluminum cylinder die casting of its compressor is by top shoe, main shaft cover half Core, compression cylinder fixed mold, cross gate, sprue bush, sliding block, side running channel, compression cylinder dynamic mould core, main shaft dynamic mould core group Into；Described compressor casing profile is designed as cylinder, and its center is spindle hole, the grade of periphery 7 point arrangement compression cylinder；Described In the structure of die casting because on the outside of cylinder body not finishing but have many structure holes and different boss, it is therefore overall Design is to give cylinder body figuration with two large-scale sliding blocks of top shoe and sliding block, and two sliding blocks respectively constitute the hemicycle of casting profile Arc；7 described compression cylinders and central principal axis hole, then main shaft fixed mold respectively on active and inactive mold, compression cylinder fixed mold, Compression cylinder dynamic mould core, main shaft dynamic mould core docking figuration；Described dynamic, the segmentation of cover half upper core length should be forty and sixty percent, Dynamic mould core is slightly longer, makes the parcel power of dynamic model larger, to ensure that casting is not detained on cover half during die sinking；The 14 of active and inactive mold Equal design point cooling device on individual core, so that compression cylinder top layer can obtain finer and close crystallization, while can pass through mould pair The quick cooling of liquid aluminium alloy prevents the precipitation of primary silicon；Described side running channel is designed on sliding block；Described sprue bush Design is contacted in rear plane with material cylinder, and front end face is mounted directly in the plane of sliding block；Described cross gate is opened in cover half Side, its length is defined by the projected area without departing from sliding block, in order to avoid leave overlap on the composition surface of top shoe and sliding block； The end face that running channel turns in cylinder body is opened up in the side of cross gate, can so enable aluminum alloy to fill whole die cavities；The mould is also set up Pre-reset mechanism, in order to avoid the interference of push rod and top shoe and sliding block；It is closer to the distance due to mold design medium casting and material head, Cross gate is very short, and the dynamic loss of energy of die casting is smaller, and the transmission of pressure is very efficient, so that the qualification rate of casting reaches 98%.

Using patent of the present invention will be appreciated that：Four or six are divided into due to be related to upper active and inactive mold upper core length Open, dynamic mould core is slightly longer, make the parcel power of dynamic model larger, it is ensured that casting is not detained on cover half during die sinking；Secondly dynamic Design point cooling device on 14 cores of cover half, so that compression cylinder top layer can obtain finer and close crystallization, while can pass through Quick cooling of the mould to liquid aluminium alloy prevents the precipitation of primary silicon；Thirdly due to design medium casting and material head distance compared with Closely, cross gate is very short, and the dynamic loss of energy of die casting is smaller, and the transmission of pressure is very efficient；Post is amenable to using this patent product The reciprocal high-speed friction in axial direction is filled in, cylinder body bears 2.2MPa pressure, moreover it is possible to substantially mitigate cylinder body weight, the qualification rate of casting More than 98% has been reached, Improving The Quality of Products has been finally reached, reduction production cost, raising casting qualified rate, enhancing enterprise are in city Competitiveness in.
