Abstract
The utility model discloses a track frog casting is with easy spacer core box of sand system, including the core box bottom plate with establish the core box vertical wall at core box bottom plate edge all around, on the core box bottom plate, it is equipped with the ingate model to found the wall inboard at the core box, be equipped with the strengthening rib model that is used for the shaping to connect the strengthening rib of dead head and foundry goods on the core box bottom plate founds the wall inboard. A reinforcing rib cavity is additionally arranged on a sand-made easy-separation piece manufactured by a core box, so that two reinforcing ribs are additionally arranged between a casting head and a casting after casting is finished, and the reinforcing ribs are connected with the casting head and the casting, so that the phenomenon of meat breaking of the casting caused by the falling of the casting head is not easily caused in the vibrating shakeout process of the casting.
Description
Technical Field
The utility model belongs to the technical field of the track frog production technique and specifically relates to a track frog casting is with easy spacer core box of sand system is related to.
Background
The sand easy-separation core box is used for manufacturing a novel sand easy-separation, the sand easy-separation is placed between the casting head reserved cavity and the casting piece reserved cavity when a sand mold is manufactured, and the sand easy-separation plays a role in controlling the speed and the direction of filling a casting mold with molten metal during pouring and has a certain slag blocking effect.
The production of the high manganese steel frog adopts an integral casting mode, and in order to facilitate the cleaning and machining of castings, easy-to-separate sheets are often adopted for connection between the castings and a casting head; the existing easy spacer is mostly a square plate-shaped structure, and an ingate cavity is arranged on the easy spacer, so that the use of the easy spacer of the structure often brings the phenomenon that the casting breaks at the easy spacer in the vibration shakeout process to break off the meat, the casting is scrapped due to meat deficiency or is welded and repaired, and the production cost is increased and the labor intensity is increased.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art, the utility model aims to solve the technical problem that a track frog casting is with easy spacer core box of sand system is provided to reach and effectively avoid the foundry goods end to break the purpose of meat phenomenon off with the fingers and thumb.
In order to solve the technical problem, the utility model discloses the technical scheme who adopts is:
the sand-made easy-parting core box for casting the track frog comprises a core box bottom plate and core box vertical walls arranged on the edges of the periphery of the core box bottom plate, wherein an ingate mold is arranged on the inner side of each core box vertical wall on the core box bottom plate, and a reinforcing rib mold for forming reinforcing ribs for connecting a casting head and a casting is arranged on the inner side of each core box vertical wall on the core box bottom plate.
Furthermore, the reinforcing rib model is connected with the inner side of the core box vertical wall.
The reinforcing rib model is a block with a small top and a large bottom.
The core box vertical wall comprises main side plates which are oppositely arranged, and a pair of end plates which can adjust the position are arranged between the main side plates.
The ingate model and the reinforcing rib model are both positioned in the middle between the pair of main side plates.
The reinforcing rib model is attached to the inner side of the end plate at one end, and the ingate model is arranged close to the inner side of the end plate at the other end.
Compared with the prior art, the utility model, have following advantage:
this track frog casting is with easy spacer core box of sand system structural design is reasonable, the easy spacer of sand system that makes the core box produce has newly increased a strengthening rib cavity, thereby increase two strengthening ribs between casting head and the foundry goods after the pouring is accomplished, this strengthening rib is connected casting head and foundry goods, make the foundry goods difficult production in the vibrations knockout in-process break the meat phenomenon off with the fingers and thumb because of the foundry goods that the casting head dropped the production, the frog waste product reduces, repair welding reprocesses operation intensity greatly reduced, the production cost is reduced, the labor waste that repair operation brought has been avoided simultaneously.

fig. 1 is a schematic pouring diagram of the present invention.
Fig. 2 is a schematic top view of fig. 1.
Fig. 3 is a schematic structural diagram of the core box of the present invention.
Fig. 4 is the structural schematic diagram of the easy-to-separate piece of the present invention.
In the figure:
1. the casting process comprises the following steps of frog casting, 2-casting head, 3-sand-made easy-separation piece, 4-broken meat part, 5-core box bottom plate, 6-core box vertical wall, 7-fixing piece, 8-ingate model, 9-reinforcing rib model, 10-ingate cavity and 11-reinforcing rib.
Detailed Description
The following description of the embodiments of the present invention will be made in detail with reference to the accompanying drawings.
As shown in fig. 1 to 4, the sand-made easy-parting core box for casting the track frog comprises a core box bottom plate 5 and a core box vertical wall 6 arranged on the periphery of the core box bottom plate, wherein an ingate mold 8 is arranged on the inner side of the core box vertical wall on the core box bottom plate, and a reinforcing rib mold 9 for forming reinforcing ribs for connecting a casting head and a casting is arranged on the inner side of the core box vertical wall on the core box bottom plate.
The reinforcing rib model 9 is a block with a small top and a large bottom, so that the sand mold demoulding operation is facilitated.
The core box vertical wall 6 comprises main side plates which are oppositely arranged, and a pair of end plates with adjustable positions are arranged between the main side plates; preferably, the opposite positions of the pair of main side plates are provided with clamping grooves corresponding to the end portions of the end plates, and the clamping grooves of each main side plate are arranged in parallel to facilitate the adjustment of the end portions.
A fixing piece 7 is arranged on the bottom plate of the core box between the pair of main side plates and positioned on the outer side of the end plate, and the fixing piece can be fixed on the bottom plate of the core box through a fastening piece and is used for reinforcing the end plate.
The reinforcing rib model is connected with the inner side of the vertical wall of the core box; the ingate mould and the reinforcing rib mould are both positioned in the middle between the pair of main side plates. The reinforcing rib model is attached to the inner side of the end plate at one end, and the inner pouring gate model is arranged close to the inner side of the end plate at the other end.
A reinforcing rib cavity is additionally arranged on the sand-made easy separation piece 3 made of the core box and corresponds to the ingate cavity 10, so that two reinforcing ribs are additionally arranged between the casting head 2 and a casting after the casting is finished, the reinforcing ribs 11 are connected with the casting head and the frog casting 1, and the casting is not easy to break meat due to the fact that the casting falls off in the vibrating shakeout process.
Therefore, the problems that the existing meat breaking part 4 is easy to break meat off, the waste products of the track frog are reduced, the intensity of repair welding repair operation is greatly reduced, the production cost is reduced, and the labor waste caused by repair welding repair operation is avoided.
