Further technical scheme, described jacket layer is Steel material, and described interior jacket layer is embedded in the inner side of described jacket layer.
Further technical scheme, the lower end surface part of described interior jacket layer extends to form end layers to its outer radial, the lower end surface of jacket layer described in described end layers cover part.
In technique scheme, described jacket layer is threaded with described sand plate of penetrating.
Further technical scheme, described blasting unit, described sand-shooting head body and described in the one or more inwall penetrated in sand plate be provided with polytetrafluoroethylene floor.
In technique scheme, described blasting unit is provided with penetrates sand passage, described sand-shooting head body is provided with penetrates sand chamber, described sand plate of penetrating is provided with sand-spraying hole, describedly penetrate the charging port penetrating sand chamber described in sand channel connection, described penetrate sand plate be tightly connected described in penetrate the discharging port of sand chamber, described in penetrate Sha Zui and be connected in described sand-spraying hole, described in penetrate sand mouth be communicated with described in penetrate sand chamber to extraneous.
Because technique scheme is used, the present invention compared with prior art has following advantages:
1. in the present invention, the internal layer penetrating sand mouth is set to polytetrafluoroethylmaterial material, because polytetrafluoroethylmaterial material has good resistance to elevated temperatures, good effect of heat insulation can be played, prevent cold core resin or the inorganic resin melting and solidification when penetrating sand, and then ensure that penetrating sand mouth can not block and to penetrate sand flow smooth;
2. in the present invention, the internal layer penetrating sand mouth is set to polytetrafluoroethylmaterial material, because polytetrafluoroethylmaterial material has good greasy property, can ensure that cold core resin or inorganic resin can not stick to the inwall penetrating sand mouth, and then ensure that penetrating sand mouth can not block and penetrate sand flow journey;
3. in the present invention, interior jacket layer is set to polytetrafluoroethylmaterial material, jacket layer is set to Steel material, and jacket layer is more excellent with the switching performance penetrating sand plate on the one hand, on the other hand, avoids mould to contact with the direct of interior jacket layer, the life-span of jacket layer in extending.

Wherein: 100, blasting unit; 101, sand passage is penetrated; 200, sand-shooting head body; 201, sand chamber is penetrated; 300, sand plate is penetrated; 400, Sha Zui is penetrated; 401, interior jacket layer; 402, jacket layer; 403, end layers.
Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described:
Embodiment one
See Fig. 1 and Fig. 2, as shown in legend wherein, a kind of sand-shooting head device of core making machine, comprise the blasting unit 100 set gradually from top to bottom, sand-shooting head body 200, penetrate sand plate 300 and penetrate sand mouth 400, blasting unit 100 is provided with penetrates sand path 10 1, sand-shooting head body 200 is provided with penetrates sand chamber 201, penetrate sand plate 300 and be provided with several sand-spraying hole (not shown)s, penetrate sand path 10 1 to be communicated with the charging port penetrating sand chamber 201, penetrate sand plate 300 and be arranged on the discharging port penetrating sand chamber 201, penetrate sand mouth 400 comprise the interior jacket layer 401 of tubulose and be located at the jacket layer 402 in outside of interior jacket layer 401, interior jacket layer 401 is polytetrafluoroethylmaterial material, jacket layer 402 is Steel material, interior jacket layer 401 is embedded in the inner side of jacket layer 402 and interior jacket layer 401 covers the inwall of whole jacket layer 402, the thickness of interior jacket layer 401 is 0.1CM.
When penetrating sand, penetrate sand mouth 400 first decline insert core box penetrate in sand mouth, the molding sand penetrated in sand path 10 1 enters in core box by interior jacket layer 401 under compressed-air actuated effect, in core-shooting process, on the one hand, because interior jacket layer 401 has good heat-proof quality, molding sand through interior jacket layer 401 can not melting and solidification, on the other hand, because interior jacket layer 401 has good lubricity, also can not be detained to be connected to through the molding sand of interior jacket layer 401 penetrates on sand mouth 400, therefore can not cause the blocking of penetrating sand mouth 400, ensures to penetrate sand flow smooth.
