The specific implementation mode is as follows:
the invention will now be further described with reference to specific embodiments, with reference to figures 1 to 4:
the utility model provides a mold processing for self priming pump head, including cope match-plate pattern 1 and the lower bolster 2 of assembling from top to bottom, be formed with the embryo chamber between cope match-plate pattern 1 and the lower bolster 2, be provided with the psammitolite 3 corresponding with self priming pump head inner chamber structure in the embryo chamber, and be formed with the die cavity that is used for the casting to form the self priming pump head between psammitolite 3 and the embryo chamber, offer on the psammitolite 3 and be used for carrying out the separated runner to the intake antrum of self priming pump head and go out the water cavity and separate logical groove 4, the circulation is separated and is led to the inslot and has been placed runner division board 5, runner division board 5 and self priming pump head are the fashioned integral type structure of secondary casting.
The utility model discloses a it separates logical groove 4 to have seted up the runner on psammitolite 3, and place runner division board 5 that has shaped and separate logical inslot 4 at the runner, make when self priming pump head casting moulding, runner division board 5 and self priming pump head can the secondary casting shaping and form the integral type structure, because of runner division board 5 is shaping early, the event is no longer because of expend with heat and contract with cold and is used in on the wall of self priming pump head, thereby the outer wall of the self priming pump head that obtains after the casting can level and smooth, no indenture.
Furthermore, consider that the steam separation baffle also can lead to the indenture to appear in the outer wall of self priming pump head because of expend with heat and contract with cold in the actual casting processing, consequently, the utility model discloses in, offer on the psammitolite 3 and be used for carrying out the divided steam at the play water cavity of self priming pump head to the steam and separate logical groove 6, the steam is separated and is placed steam division board 7 in leading to groove 6, and steam division board 7 is the fashioned integral type structure of secondary casting with the self priming pump head. Namely, the same principle as the runner partition plate 5 is adopted, and the formed water-vapor partition plate 7 is placed in the water-vapor partition through groove 6, so that when the self-priming pump head is cast and formed, the water-vapor partition plate 7 and the self-priming pump head can be cast and formed for the second time to form an integrated structure.
Meanwhile, in order to improve the production efficiency, a main runner 8 for flowing of the molten metal is formed between the upper template 1 and the lower template 2, a casting opening 9 communicated with the main runner 8 is formed in the upper template 1, and more than two blank cavities are formed in each blank cavity and are communicated with the main runner 8. In the present embodiment, there are two embryo cavities, and the two cavities are arranged in central symmetry.
Furthermore, in order to place the sand core 3 between the upper template 1 and the lower template 2 and take out the self-priming pump head formed on the outer surface of the sand core 3 from the upper template 1 and the lower template 2, the outer wall surface of the sand core 3 extends outwards to the outside of the embryo cavity and forms a holding part 10. And the sand core 3 and the self-sucking pump head after being taken out only need to carry out crushing treatment on the sand core 3, and the finished self-sucking pump head can be obtained.
Considering that the sand core 3 is easy to break, in order to enable the holding part 10 to be stably connected with the sand core 3, the end surfaces of the sand core 3 corresponding to the water inlet end, the water outlet end and the water injection end port of the self-priming pump head extend outwards and are fixedly connected with the holding part 10.
The above-mentioned embodiment is only one of the preferred embodiments of the present invention, and the scope of the present invention is not limited thereto, so: all equivalent changes made according to the shape, structure and principle of the utility model are covered within the protection scope of the utility model.
