阅读说明：本技术 一种导模法生长单晶的模具及组件及加工方法 (Die and assembly for growing single crystal by guide die method and processing method ) 是由 张学锋 肖学峰 于 2020-03-26 设计创作，主要内容包括：一种导模法生长单晶的模具,包括相对设置的内侧模板、外侧模板,相对设置的内侧模板、外侧模板之间间隔熔体流过的狭缝,内侧模板、外侧模板的相对内壁为光滑表面,还在内侧模板的上端面开设内侧倒角,还在外侧模板的上端面开设外侧倒角,内侧倒角和外侧倒角相对设置,用于控制晶体形状的厚度,还在内侧模板、外侧模板的侧壁上开设供溶体进入狭缝的过孔,本发明中,相对的两个模板之间内壁光滑无阻力,拉制时利用毛细原理,生长处于狭缝形状相同的晶体。(A mould for growing monocrystal by guide mould method is composed of internal and external formworks, and the slits between said internal and external formworks for the molten substance to flow through.)

1. A die for growing single crystal by a guide die method is characterized in that: the crystal shape control device comprises an inner side template and an outer side template which are oppositely arranged, and a slit through which a melt flows is arranged between the inner side template and the outer side template which are oppositely arranged at intervals, wherein the opposite inner walls of the inner side template and the outer side template are smooth surfaces, an inner side chamfer is arranged on the upper end surface of the inner side template, an outer side chamfer is arranged on the upper end surface of the outer side template, the inner side chamfer and the outer side chamfer are oppositely arranged and used for controlling the thickness of a crystal shape, and a through hole through which the melt enters the slit is arranged on the side walls of the inner side template and the.

2. A mold for growing a single crystal according to claim 1, wherein: the end surfaces of the inner chamfer and the outer chamfer are planes or arc surfaces.

3. A mold for growing a single crystal according to claim 1, wherein: and through holes are formed in the bottoms of the side walls of the inner side template and the outer side template.

4. A mold for growing a single crystal according to claim 3, wherein: and the upper part of the outer wall of the inner template is provided with an inner unfilled corner, and the upper part of the outer wall of the outer template is provided with an outer unfilled corner.

5. A mold for growing a single crystal according to claim 1, wherein: the inner side template and the outer side template are flat plate pieces and are used for producing flat strip-shaped thin crystal.

6. A mold for growing a single crystal according to claim 1, wherein: the inner side template and the outer side template are circular rings, and the slits arranged between the inner side template and the outer side template at intervals are circular rings and are used for drawing the annular shell-shaped thin-walled crystal.

7. A mold for growing a single crystal according to claim 1, wherein: the inner side template and the outer side template are in a prism shape, and the slits arranged between the inner side template and the outer side template at intervals are also in a prism shape and are used for drawing prism thin-wall crystals.

8. An assembly for growing single crystals by the guided mode method, comprising: the crucible top is open and is used for containing melt and placing a mold, the width of the mold is smaller than that of the crucible so that the side walls of the two sides of the mold are not in contact with the inner wall of the crucible, the inner side unfilled corner and the outer side unfilled corner of the mold have the same grooving height, the grooving height is the same as the side wall height of the crucible, the cover plate is a flat plate, a through clamping groove is formed in the middle of the cover plate, the grooving shape of the clamping groove is matched with that of the unfilled corner of the mold, the clamping groove of the cover plate is lapped on the unfilled corner end face of the mold, the outer side edge of the cover plate is lapped on the side wall of the crucible, and the mold is the mold for growing single crystals by the guide mold method according to any one of claims.

9. A processing method of a die for growing single crystals by a guide die method is characterized by comprising the following steps:

machining the inner side template and the outer side template;

and mechanically polishing the inner walls of the inner template and the outer template to form a smooth plane.
