CN201579379U - Roll mold - Google Patents

Abstract

The utility model discloses a roll mold, wherein a gate (1), a riser (3), a cold section (4) and a bottom box (5) which are coaxially connected sequentially to form a casting cavity. The roll mold is characterized in that a guide pipe (2) used for being injected with liquid steel is arranged inside the casting cavity. The bottom portion of the roll mold can not be impacted, thereby avoiding breaking the bottom portion of the mold.

Description

A kind of roller mold

Technical field

The utility model relates to a kind of roll casting die.

Background technology

Roll is the vitals of roll forming.Roll needs to bear bigger roll-force in the operation of rolling, so the production of roll is all passed through to cast one-time formed.Roll production is cast by the roll casting die.The roll casting die comprises coaxial cast gate, rising head, cold mould and the under casing that links to each other successively, and molten steel enters in the mould from cast gate, fills with mould gradually, finishes casting work from face.The shortcoming of above-mentioned mould is that the molten steel of working as big density enters at the inflow cavity bottom from cast gate, be the movement of falling object, will produce huge impact power, easily cause the under casing of cavity bottom to damage, thereby both caused person property's damage, also environment had been caused huge destruction.

The utility model content

The purpose of this utility model be exactly solve existing roller mold invar water the freely falling body Impact mould the bottom and damage.

The technical solution adopted in the utility model is: a kind of roller mold, it comprises that the coaxial cast gate that links to each other successively, rising head, cold mould and under casing constitute the foundry goods die cavity, it is characterized in that being provided with in the described foundry goods die cavity being used for the conduit of drainage molten steel.

Adopt technique scheme, during casting, molten steel flows in conduit, and directly drainage is to the bottom of die cavity, and molten steel just can not produce the movement of falling object like this, does not impact thereby can not produce the bottom, also just can not produce die cavity and destroy.

In sum, the utility model beneficial effect is: since the utility model adopt conduit with the direct drainage of molten steel to mold bottom, therefore can not make molten steel produce the movement of falling object, impact thereby can not produce the bottom, so just can not destroy the bottom of mould.

Description of drawings

Fig. 1 is the utility model structural representation.

Among the figure, 1, cast gate, 2, conduit, 3, rising head, 4, cold mould, 5, under casing.

The specific embodiment

A kind of roller mold of the utility model, as shown in Figure 1, it comprises that the coaxial cast gate 1 that links to each other successively, rising head 3, cold mould 4 and under casing 5 constitute the foundry goods die cavity, are provided with the conduit 2 that is used for injecting molten steel in the described foundry goods die cavity.

The utility model in use, after molten steel was filled with, conduit was promptly stayed in the foundry goods, became the part of foundry goods.

Claims (1)

1. roller mold, it comprises the coaxial cast gate [1] that links to each other successively, rising head [3], cold mould [4] and under casing [5] formation foundry goods die cavity, it is characterized in that being provided with in the described foundry goods die cavity conduit [2] that is used for injecting molten steel.
