Technical field
The utility model is related to steel-making oxygen gun sprayer manufacture field, more particularly to a kind of die casting of oxygen gun sprayer.
Background technology
The method of currently manufactured steel-making oxygen gun sprayer is roughly divided into following several：1st, monoblock cast：Sand mold is first carried out again will
Copper water is injected into sand mold, because sand casting density is low, have the phenomenons such as stomata, trachoma, so heat-conducting effect is bad.2nd, temperature and pressure
Combination：It is to be put into mould extrude a shower nozzle end cap with forcing press and a shunting body is combined after copper billet is heated, its
Have the disadvantage that big difficulty of processing, high cost, yield rate are low.3rd, extruding combination：Sand casting blank is first used, then cast member is split,
Machining is carried out respectively, the end cap after processing is carried out into heating extruding to increase density, then the shunt head after processing is carried out
Brazing flux is welded, and has the disadvantage complex process, high cost.
The patent document of Application No. 200920014712.3 discloses a kind of " high density oxygen lance nozzle mold ", is inlaid with
The upper mould of movable mold constitutes a die cavity with lower mould by guide pillar, there is the hole for setting pin iron, the die cavity bottom of lower mould on guide pillar
Portion is provided with the sliding block beneficial to the demoulding.The mould be using to the extrusion process of liquid copper manufacture steel-making oxygen gun sprayer, can with gram
The more than clothes shortcomings of several production technologies.But in actual applications due to upper die and lower die installation and removal and the demoulding all
Artificial operation is needed, and mold temperature is very high, is very easy to be burned.In addition, in the mould with suppression be on
Active module in mould, but in pressing process, active module to the cylindrical place of oxygen gun sprayer end cap be pressure less than, so
So that being also easy to produce crackle at the oxygen gun sprayer end cap of product.
Utility model content
The purpose of this utility model is to overcome above the deficiencies in the prior art, there is provided a kind of die casting of oxygen gun sprayer,
Ensure product quality, simplify manufacturing process, reduce production cost, installation, dismounting and the demoulding are replaced manually using machinery, it is ensured that
Production safety.
To achieve the above object, the utility model is realized using following technical scheme：
A kind of die casting of oxygen gun sprayer, including lower mould, upper mould, demoulding push rod, thermal resistance contiguous block, in the upper end of upper mould
The demoulding push rod being slidably connected therewith is provided with, casting die cavity, thermal resistance contiguous block are constituted between lower mould and upper mould and demoulding push rod
Mould in connection, the side of mould bottom is provided with stripping chute on described.
Also include demoulding push rod connecting plate and spring, demoulding push rod connecting plate is connected with the upper end of the demoulding push rod, bullet
Spring is arranged between demoulding push rod connecting plate and upper mould.
The demoulding pull bar connecting plate is connected by connecting screw with the upper end of the demoulding push rod.
Also include heating plate, heating plate is arranged on the bottom of lower mould.
The thermal resistance contiguous block is connected through a screw thread mould.
Compared with prior art, the beneficial effects of the utility model are：
A kind of die casting of oxygen gun sprayer, is suppressed whole die cavity by upper mould, it is ensured that product oxygen gun sprayer
Global density, it is ensured that product quality；Using extrusion process, manufacturing process is simple, and production cost is relatively low；The installation of mould,
Dismounting and the demoulding replace artificial using machinery, it is ensured that production safety.

Specific embodiment
Implementation method of the present utility model is further illustrated below in conjunction with the accompanying drawings：
See Fig. 1, a kind of die casting of oxygen gun sprayer, including lower mould 2, upper mould 3, demoulding push rod 5, thermal resistance contiguous block 7,
The upper end of upper mould 3 is provided with the demoulding push rod 5 being slidably connected therewith, and casting is constituted between lower mould 2 and upper mould 3 and demoulding push rod 5
Die cavity, the upper mould 3 of the connection of thermal resistance contiguous block 7, is shown in Fig. 2, and the side of the bottom of mould 3 is provided with stripping chute 12 on described.
Also include demoulding push rod connecting plate 6 and spring 4, demoulding push rod connecting plate 6 connects with the upper end of the demoulding push rod 5
