Abstract
The molten steel casting passage of model casting, it comprises one by be connected together one of two foundry goods symmetries middle cross pouring channel, described cross pouring channel comprises the sprue gate of upper end, two horizontally disposed cross gates and the sprue arranged downward vertically, the limit, foundry goods upper end be connected in parallel below the downward UNICOM in two ends of the cross gate on both sides, the both sides, bottom of sprue respectively UNICOM are arranged in the foundry goods center of both sides, and two foundry goods are connected together, a breach is offered below the junction of described sprue connection cross gate, make sprue at the downward affluent channel of formation turning, indentation, there both sides shape, and conflux below breach and be connected to sprue, sprue gate, upper end in described cross pouring channel and cross gate outer end, both sides are connected with the connecting rod of booster action respectively, the both sides, bottom of described sprue respectively by uniform duct UNICOM of horizontal UNICOM on the lateral face of corresponding side foundry goods, it has rational in infrastructure, easy to use, and foundry goods can be made to meet rational solidification sequence, ensures the quality of product, especially can solve the features such as foundry goods shrinkage cavity and porosity problem preferably.
Description
Technical field
The utility model relates to a kind of molten steel casting passage being exclusively used in model casting, belong to investment casting process technical field.
Background technology
In existing investment casting process, often can encounter such class foundry goods, this kind of foundry goods both sides wall thickness, midfeather is thin, both sides are that thermal center needs feeding in other words, when designing the running gate system of this kind of foundry goods, often can consider molten steel casting passage as shown in Figure 1, it is connected together symmetrically by a middle cross pouring channel by two foundry goods 11, described cross pouring channel comprises the sprue gate 12 of upper end, two horizontally disposed cross gates 13 and the sprue 14 arranged downward vertically, the limit, foundry goods 11 upper end be connected in parallel below the downward UNICOM in two ends of the cross gate 13 on both sides, the both sides of sprue 14 respectively UNICOM are arranged in foundry goods 11 center of both sides, and two foundry goods 11 are connected together.
Above-mentioned cross pouring channel design also exists a very large problem, and molten steel is poured into from casting gate, and be first be full of bottom along sprue and expire gradually, when flooding whole foundry goods completely, molten steel flows to foundry goods from the cross gate of side again; Because the centre position of foundry goods is solidified in advance, molten steel can not flow through centre position to bottom feeding from cross gate through foundry goods top again, causes the middle lower bottom part of foundry goods side to have shrinkage cavity and porosity.
Summary of the invention
The purpose of this utility model is the deficiency overcoming prior art existence, and provide a kind of rational in infrastructure, easy to use, foundry goods can be made to meet rational solidification sequence, ensure the quality of product, especially can solve the molten steel casting passage of the model casting of foundry goods shrinkage cavity and porosity problem preferably.
The purpose of this utility model has been come by following technical solution, a kind of molten steel casting passage of model casting, it comprises one by be connected together one of two foundry goods symmetries middle cross pouring channel, described cross pouring channel comprises the sprue gate of upper end, two horizontally disposed cross gates and the sprue arranged downward vertically, the limit, foundry goods upper end be connected in parallel below the downward UNICOM in two ends of the cross gate on both sides, the both sides, bottom of sprue respectively UNICOM are arranged in the foundry goods center of both sides, and two foundry goods are connected together, a breach is offered below the junction of described sprue connection cross gate, make sprue at the downward affluent channel of formation turning, indentation, there both sides shape, and conflux below breach and be connected to sprue.
Sprue gate, upper end in described cross pouring channel and cross gate outer end, both sides are connected with the connecting rod of booster action respectively; The both sides, bottom of described sprue respectively by uniform duct UNICOM of horizontal UNICOM on the lateral face of corresponding side foundry goods.
The utility model has rational in infrastructure, easy to use, and foundry goods can be made to meet rational solidification sequence, ensures the quality of product, especially can solve the features such as foundry goods shrinkage cavity and porosity problem preferably.
Accompanying drawing explanation
Fig. 1 is the structural representation of prior art.
Fig. 2 is structural representation of the present utility model.
Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be described in detail: shown in Fig. 2, the molten steel casting passage of a kind of model casting described in the utility model, it comprises one by be connected together one of two foundry goods 21 symmetries middle cross pouring channel 22, described cross pouring channel 22 comprises the sprue gate 23 of upper end, two horizontally disposed cross gates 24 and the sprue 25 arranged downward vertically, the limit, foundry goods 21 upper end be connected in parallel below the downward UNICOM in two ends of the cross gate 24 on both sides, the both sides, bottom of sprue 25 respectively UNICOM are arranged in foundry goods 21 center of both sides, and two foundry goods 21 are connected together, a breach 26 is offered below the junction that described sprue 25 connects cross gate 24, make sprue at the downward affluent channel 27 of formation turning, indentation, there both sides shape, and conflux below breach 26 and be connected to sprue 25.
Shown in figure, the sprue gate, upper end 23 in described cross pouring channel and both sides cross gate 24 outer end are connected with the connecting rod 28 of booster action respectively; The both sides, bottom of described sprue 25 respectively by uniform duct 29 UNICOM of horizontal UNICOM on the lateral face of corresponding side foundry goods 21.
The utility model offers a breach below the junction connecting cross gate, this breach serves molten steel shunting action, so a part of steel flow enters foundry goods bottom sprue, another part molten steel flows to foundry goods from cross gate simultaneously, two strands of molten steel can not produce strong head-on collision, foundry goods side has molten steel to enter always, the medium position Feeding channel of foundry goods can not solidify in advance, the order of solidifying is always: the molten steel of cross gate is through foundry goods top, pass through middle part feeding again to the bottom of foundry goods, whole foundry goods meets solidification sequence, ensure the quality of product, solve shrinkage cavity and porosity problem well.
