Abstract
The utility model provides a piston foundry goods the gating system, water at the pouring basin of cross gate and the overflow of multichannel down sprue and the setting of down sprue bottom including cross gate, setting, the cross gate is used for connecting down sprue and pouring basin, the down sprue is provided with rising head and spoiler. The utility model discloses a piston foundry goods the gating system improves cross gate, down sprue structural design, waters and collects pouring chill water at the beginning through setting up the overflow, causes the foundry goods segregation in preventing to get into the piston die cavity, sets up the feeding head, ensures the production quality of piston product.
Description
Technical field
The utility model relates to a kind of casting moulding system field, particularly relates to Piston Casting running gate system.
Background technology
Rolling piston type air-conditioner compressor, mainly be arranged in compressor of air conditioner, low-pressure gas is promoted to a kind of driven fluid machinery of gases at high pressure, it is the heart of refrigeration system, it sucks the refrigerant gas of low-temp low-pressure from air intake duct, drives piston to compress it, discharge the refrigerant liquid of HTHP to blast pipe by motor rotation, for kind of refrigeration cycle provides power, thus realize the kind of refrigeration cycle of compression → condensation → expansion → evaporation.
Rolling piston is a strength member of compressor of air conditioner, the performance of rolling piston directly affects the service life of air-conditioning, along with the development in epoch, each air-conditioning producer is more and more higher to the hardness of piston, tensile strength, bending strength, heat endurance, wearability, corrosion resistance, processing characteristics, geometric accuracy, the requirement in service life.
In piston blank castings production process, affect by template dimensions, cause the long flow path that pouring in vertically clamped moulds pressure is large, molten iron flows through die cavity, in addition the molten iron degree of supercooling entering die cavity early stage is large, easy formation carbide or distribution of carbides segregation, and cause the underproof present situation of row's piston metallographic structure bottom template.
Utility model content
In view of the above, be necessary to provide a kind of Piston Casting running gate system that can prevent from being formed carbide or distribution of carbides segregation.
A kind of Piston Casting running gate system, comprise cross gate, be arranged on the overflow running channel of the cup of cross gate and multiple tracks sprue and the setting of sprue bottom, described cross gate is for connecting described sprue and cup, and described sprue is provided with rising head and spoiler.
Further, described sprue is four roads.
Further, each sprue is provided with four spoilers.
Further, described rising head end is formed with riser neck.
Compared to prior art, Piston Casting running gate system of the present utility model, improves cross gate, sprue structural design; the chill water of cast beginning is collected by arranging overflow running channel; prevent from entering in piston die cavity and cause foundry goods segregation, feeding head is set, guarantee the quality of production of piston product.
Accompanying drawing explanation
Fig. 1 is Piston Casting running gate system front view of the present utility model;
Fig. 2 is the Piston Casting running gate system rearview of utility model.
Detailed description of the invention
By describing technology contents of the present utility model, structural feature in detail, realized object and effect, accompanying drawing is coordinated to be explained in detail below in conjunction with embodiment.
Incorporated by reference to consulting Fig. 1 and Fig. 2, Piston Casting running gate system of the present utility model, is arranged on mould shaping plate 100, comprises cross gate 10, is arranged on the cup 20 of cross gate 10 and multiple tracks sprue 30.Described cross gate 10 is for connecting sprue 30 and cup 20.Described sprue 30 is provided with rising head (not shown) and spoiler 50.Described spoiler 50 is for the floating sand of the oxidizing slag that stops molten iron to produce in flowing and generation.Described cup 20 enters cross gate 10 for guiding molten iron.
Preferably, sprue 30 is four roads, and each sprue 30 is provided with four spoilers 50.
Further, described rising head end is formed with riser neck (not shown).
Further, described sprue 30 bottom is provided with overflow running channel 70, for collecting the chill water that cast starts, preventing from entering in piston die cavity and causing foundry goods segregation.
Piston Casting running gate system of the present utility model; design is optimized to piston template; improve cross gate, sprue structural design arrange overflow running channel 70 collect cast start chill water; prevent from entering in piston die cavity and cause foundry goods segregation; feeding head is set, guarantees the quality of production of piston product.
The foregoing is only preferred embodiment of the present utility model; not thereby the scope of the claims of the present utility model is limited; every equivalent structure transformation utilizing the utility model description and accompanying drawing content to do; or be directly or indirectly used in other relevant technical fields, be all in like manner included in scope of patent protection of the present utility model.
