Abstract
A kind of sand shooting mouth for preventing scab is the utility model is related to, including：Polytetrafluorethylecoatings coatings and sand shooting mouth, thoroughly solves the problems, such as sand shooting mouth inwall scab；Sand shooting mouth inwall finishing process is saved, declines nozzle cost of manufacture；The efficiency of explosion core mould is lifted, nozzle maintenance procedures can almost be omitted；Nozzle penetrates sand amount stabilization, and production efficiency is obviously improved；Sand shooting mouth sectional area is stable, and no longer periodically sand parameter is penetrated in adjustment, penetrates sand steady quality.
Description
Technical field
The utility model belongs to casting explosion core mould technical field, and in particular to a kind of sand shooting mouth, it is more particularly to a kind of anti-
The only sand shooting mouth of scab.
Background technology
Casting by the use of explosion core mould all using resin as core bonding agent, but by cold core shooting mode structure is determined.It is mixed with
The resin sand of resin must be entered in mold cavity by sand shooting mouth.Casting resin has very strong adhesiveness, and resin sand passes through
Just one layer of resin is stained with during sand shooting mouth inside sand shooting mouth, being bonded at the resin bed of nozzle inwall can slowly solidify, and form one layer very
Firm cured layer.Explosion core mould often produces a mould and is just bonded one layer of resin (solidifying sometimes together with sand).So week and
One layer of reluctant accumulation horizon can slowly be formed in nozzle inwall by renewing, and accumulation horizon can have a strong impact on that nozzle penetrates grittiness energy.Its
Main cause has two：First, the increase of accumulation horizon has tied up nozzle internal cross-sectional area, the reduction of sand amount is penetrated in the unit interval, is extended
Shooting time；Second, irregular accumulation horizon, increases resin sand and projects resistance.It is conventional to do in order to not influence sand shooting mouth performance
Method is to need constantly to carry out the cleaning of inwall resin bed in sand shooting mouth, and the sand shooting mouth of big core box almost needs to clear up everyday, even if
It is sand removal everyday, the nozzle inwall inner resin layer of one day is still slowly being accumulated, and sand shooting mouth performance is still gradually reducing.In addition
A kind of method is that the finishing of sand shooting mouth inwall is reached into very smooth finish surface, and such cost is very high but simply extends nozzle inwall
Cleaning time does not solve the problems, such as inwall scab, and this has a strong impact on explosion core mould production efficiency and the quality of production.
Therefore, efficiency high can be realized by how designing one kind, and cost is low, and the sand shooting mouth without periodic cleaning turns into this area
The problem of urgent need to resolve.
Utility model content
The utility model is in view of the shortcomings of the prior art, there is provided a kind of sand shooting mouth for preventing scab, thoroughly solves sand shooting mouth
Inwall scab problem；Sand shooting mouth inwall finishing process is saved, declines nozzle cost of manufacture；Lift the efficiency of explosion core mould, nozzle
Maintenance procedures can almost be omitted；Nozzle penetrates sand amount stabilization, and production efficiency is obviously improved；Sand shooting mouth sectional area is stable, no longer fixed
Sand parameter is penetrated in phase adjustment, penetrates sand steady quality.
To solve the above problems, the technical solution adopted in the utility model is：
A kind of sand shooting mouth for preventing scab, it is characterised in that including：Polytetrafluorethylecoatings coatings and sand shooting mouth, wherein, it is described
The inwall of sand shooting mouth is handled without finishing, and the polytetrafluorethylecoatings coatings are arranged on the inwall of the sand shooting mouth.
Further, the polytetrafluorethylecoatings coatings are arranged on by way of uniformly smearing on the inwall.
Further, after the sand shooting mouth inwall smears the polytetrafluorethylecoatings coatings, fixed and penetrated by way of sintering
Polytetrafluorethylecoatings coatings on sand mouth inwall.
A kind of preparation method for the sand shooting mouth for preventing scab, it is characterised in that comprise the following steps：
1) sand shooting mouth makes：Drilling is carried out successively and sand shooting mouth inwall is fired；
2) the sand shooting mouth inwall is cleaned；
3) polytetrafluorethylecoatings coatings are uniformly applied on the sand shooting mouth inwall；
4) sintering polytetrafluoroethylfilm coating, it is made to be fixed on sand shooting mouth inwall.
The beneficial effects of the utility model are：
(1) thoroughly solves the problems, such as sand shooting mouth inwall scab；
(2) sand shooting mouth inwall finishing process is saved, declines nozzle cost of manufacture；
(3) efficiency of explosion core mould is lifted, nozzle maintenance procedures can almost be omitted；
(4) nozzle penetrates sand amount stabilization, and production efficiency is obviously improved；
(5) sand shooting mouth sectional area is stable, and no longer periodically sand parameter is penetrated in adjustment, penetrates sand steady quality.

Fig. 2 is the sand shooting mouth schematic diagram that the utility model prevents scab.
Wherein, 1, sand shooting mouth 2, adhering resin 3, polytetrafluorethylecoatings coatings
Embodiment
In order that those skilled in the art more fully understand the technical solution of the utility model, with reference to specific embodiment
The utility model is described in further detail.
According to one side of the present utility model, the utility model provides a kind of sand shooting mouth for preventing scab, such as Fig. 2 institutes
Show, including polytetrafluorethylecoatings coatings and sand shooting mouth, wherein, the inwall of the sand shooting mouth is handled without finishing, and described poly- four
PVF coating is arranged on the inwall of the sand shooting mouth.
Fig. 1 is the problem of sand shooting mouth that traditional sand shooting mouth runs into the course of the work blocks, and fat sand is penetrated when passing through sand shooting mouth
Just one layer of resin is stained with inside sand mouth, being bonded at the resin bed of nozzle inwall can slowly solidify, and form one layer of very firm solidification
Layer, and the following characteristic of polytetrafluorethylecoatings coatings：Nearly all material does not bond with polytetrafluorethylecoatings coatings, very thin layer
Also show that good non-adhesiveness energy；High temperature resistant, corrosion resistance；
Thus, the process that the utility model saves inwall finishing in traditional sand shooting mouth manufacturing process, after cleaning inwall,
Directly in inner-wall spraying polytetrafluorethylecoatings coatings, nozzle is internally formed one layer of polytetrafluorethylecoatings coatings, effectively solve in nozzle
Wall scab problem.
According to specific embodiment of the utility model, the polytetrafluorethylecoatings coatings are arranged on by way of uniformly smearing
On the inwall.
According to specific embodiment of the utility model, suitable sintering field is just provided in sand shooting mouth atelier
Institute, the secondary conveying of sand shooting mouth is avoided, saves cost, using the side of sintering in some embodiments of the present utility model
Formula realizes the fixation of polytetrafluorethylecoatings coatings, can also use other modes, it is preferred that the sand shooting mouth inwall smears described poly- four
It is sintered after PVF coating, for fixing the polytetrafluorethylecoatings coatings on sand shooting mouth inwall.
According to another aspect of the present utility model, the utility model provides a kind of making side for the sand shooting mouth for preventing scab
Method, it is characterised in that comprise the following steps：
