Abstract
According to the technical scheme, the utility model provides a feeder head structure in a casting system of a planet carrier cast of mining machinery. The feeder head structure comprises multiple feeder heads and a die cavity, wherein the plurality of feeder heads are all arranged right above the die cavity and evenly distributed.
Description
Technical field
The utility model relates to the mouth structure that emits in a kind of mining machinery planet carrier foundry goods casting system.
Background technology
Planet carrier is the important composition parts of large-scale mine coal pulverizer, not only requires will carry huge weight in the work also wear-resisting, heat-resisting, fatigue resistance.To the requirement of product casting quality than higher; In traditional casting system; Rising head in the casting system all is that design is at the foundry goods edge; This structure rising head can not well play the effect of feeding in actual casting cycle, make defectives such as the easy shrinkage porosite of main part, shrinkage cavity and the residue of foundry goods be too much, make product second-rate, yield rate is lower.
Summary of the invention
For solving above-mentioned technical problem, the utility model provides a kind of feeding effect to emit mouth structure in the mining machinery planet carrier foundry goods casting system preferably.
The technical scheme of the utility model is, the mouth structure that emits in a kind of mining machinery planet carrier foundry goods casting system with following structure is provided, and it comprises a plurality of rising heads, die cavity, described a plurality of rising heads all be positioned at die cavity directly over and evenly distribute.
After adopting said structure, the utlity model has following advantage:
The position of rising head more rationally is difficult for producing too many oxidizing slag, in casting cycle, can in time dispel the heat, and defectives such as shrinkage porosite, residue can effectively avoided or reduce to fluid infusion in time, accurately.
As improvement, rising head is an exothermic riser.Exothermic riser can at high temperature burn and guarantee that casting liquid remains high-temperature liquid state and can carry out feeding to foundry goods timely, has avoided the foundry goods hot-spot or has been heated inequality and the defectives such as shrinkage porosite that produce.
Description of drawings:
Fig. 1 is the structural representation that emits mouth structure in the utility model mining machinery planet carrier foundry goods casting system;
The specific embodiment:
Below in conjunction with accompanying drawing and specific embodiment the utility model is described further.
As shown in Figure 1, emit mouth structure in the utility model mining machinery planet carrier foundry goods casting system, it comprises a plurality of rising head 1, die cavity 2, a plurality of rising heads 1 all be positioned at die cavity 2 directly over and evenly distribute.The position of this kind rising head more rationally is difficult for producing too many oxidizing slag, in casting cycle, can in time dispel the heat, and defectives such as shrinkage porosite, residue can effectively avoided or reduce to fluid infusion in time, accurately.As further measure, rising head 1 is an exothermic riser.Exothermic riser can at high temperature burn and guarantee that casting liquid remains high-temperature liquid state and can carry out feeding to foundry goods timely, has avoided the foundry goods hot-spot or has been heated inequality and the defectives such as shrinkage porosite that produce.
Claims (2)
1. emit mouth structure in the mining machinery planet carrier foundry goods casting system, it comprises a plurality of rising heads (1), die cavity (2), it is characterized in that: described a plurality of rising heads (1) all be positioned at die cavity (2) directly over and evenly distribute.
2. emit mouth structure in the mining machinery planet carrier foundry goods casting system according to claim 1, it is characterized in that: described rising head (1) is an exothermic riser.
