For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of plastic inspection well double-layer flaring mould, comprise: main mould and be installed on the enlarging core of main mould at least one end, the second die ontology that described main mould comprises the first die ontology and matches with the first die ontology, fixed by several first fixture between described first die ontology and the second die ontology, described first die ontology and the second die ontology are combined, middle formation one die cavity, fixed by several second fixture between described enlarging core and main mould, described enlarging core is installed in die cavity and also and between the inwall of main mould forms gap.
As the preferred technical scheme of one, described enlarging core comprises the first flange that main part and main body protrude out, and the cylindrical setting of described main part, forms cylindrical gap between the inwall of described main part and main mould.
As the preferred technical scheme of one, described first die ontology is provided with mounting bracket.
As the preferred technical scheme of one, described main mould is provided with several reinforcement, is provided with the groove connected with die cavity in described reinforcement.
As the preferred technical scheme of one, the quantity of described enlarging core is two, and two enlarging cores are installed on the two ends of main mould respectively.
As the preferred technical scheme of one, described first die ontology is provided with the second flange matched with the first flange of enlarging core, described second die ontology is provided with the three-flange limit of matching with the first flange of enlarging core, described first flange is connected by bolt and nut with between the second flange, and described first flange is connected by bolt and nut with between three-flange limit.
As the preferred technical scheme of one, described main mould and enlarging core are made by iron material.
As the preferred technical scheme of one, described first fixture is hasp.
The invention has the beneficial effects as follows: the plastic inspection well double-layer flaring mould structure in the present invention is simple, easy to use, by arranging enlarging core, not only accurately can control the wall thickness of plastic inspection well, also can make the plastic inspection well inner wall smooth produced, use this kind of mould to manufacture plastic inspection well, substantially increase the quality of plastic inspection well, thus plastic inspection well can be avoided in use to occur leakage problem.

Detailed description of the invention
Below in conjunction with accompanying drawing, the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein is only for instruction and explanation of the present invention, is not intended to limit the present invention.
Refer to Fig. 1 and Fig. 2, a kind of plastic inspection well double-layer flaring mould, comprise: main mould 1 and be installed on the enlarging core 2 of main mould 1 at least one end, the second die ontology 11 that described main mould 1 comprises the first die ontology 10 and matches with the first die ontology 10, fixed by several first fixture 12 between described first die ontology 10 and the second die ontology 11, described first die ontology 10 and the second die ontology 11 are combined, middle formation one die cavity, fixed by several second fixture 3 between described enlarging core 2 and main mould 1, described enlarging core 2 is installed in die cavity and also and between the inwall of main mould 1 forms gap.Described enlarging core 2 comprises the first flange 21 that main part 20 and main body 20 protrude out, and the cylindrical setting of described main part 20, forms cylindrical gap between described main part 20 and the inwall of main mould 1.During rotation molding, the connector that can form plastic inspection well in this cylindrical gap is flowed into after heating raw materials, therefore, the setting of this enlarging core 2 substantially increases the quality of plastic inspection well, not only make the plastic inspection well connector inner wall smooth produced, and make the wall thickness controllable precise of connector.Described first die ontology 10 is provided with mounting bracket 100.Described main mould 1 is provided with several reinforcement 13, the groove 130 connected with die cavity is provided with in described reinforcement 13, this groove 130 be arranged so that the outside of the inspection shaft produced has reinforcement, thus add the structural strength of inspection shaft, in the present embodiment, the quantity of described enlarging core 2 is two, and two enlarging cores 2 are installed on the two ends of main mould 1 respectively, certainly in other embodiments, the quantity of described enlarging core 2 also can be three, four or more.In the present embodiment, described first die ontology 10 is provided with the second flange 101 matched with the first flange 21 of enlarging core 2, described second die ontology 11 is provided with the three-flange limit 110 of matching with the first flange 21 of enlarging core 2, described first flange 21 is connected by bolt and nut with between the second flange 101, and described first flange 21 is connected by bolt and nut with between three-flange limit 110.Described main mould 1 and enlarging core 2 are made by iron material, thus make mould have good structural strength.Described first fixture 12 is hasp.Certainly, in other embodiments, also can produce between described main mould 1 and enlarging core 2 by hasp or other connected mode.
During with Making mold plastic inspection well in the present invention, first raw material is poured in die cavity, by together with 2-in-1 with enlarging core for main mould 1 and fixing, then by the mode of rotational moulding, raw material is heated in die cavity and shaping, finally mould is taken off and can obtain integrated inspection shaft, manufacture very convenient, the specification of enlarging core is selected depending on real needs.
