Abstract
The utility model relates to a mould using polyethylene double resisting material to mould flange, solving the problems that the coal mine underground gas pumping and discharging uses PE pipeline at present, the docking is very difficult. The utility model realizes the integration of the pipe and the flange, which is characterized in that an outer mould sleeve (3) is provided, a guide chute (2) is arranged in the outer mould sleeve (3), a round solid T shaped sliding mould core (1) matched with the outer mould sleeve (3) is provided, a hollow flange body (5) is arranged between the outer mould sleeve (3) and the round solid T shaped sliding mould core (1), the bottom end in the outer mould sleeve (3) is placed with polyethylene double resisting material (4) according to the specified amount. The product made by the utility model has the advantages of light weight, convenient transportation and installation, simple structure, flexible and convenient operation, low labor intensity, good sealing performance, and good benefits, the utility model particularly adapts to make the connection of the coal mine underground gas pumping and discharging pipeline.
Description
Technical field:
The utility model belongs to the Machining Technology field, is specifically related to a kind of mould with the two anti-material compacting flanges of polyethylene.
Background technology:
Known to the inventor, the pipeline that draws out methane under the at present existing coal mine adopts steel pipe mostly, usually it is big to use steel pipe to exist weight, transportation is inconvenient, install complicated, easy-to-rust, the length of service is short, the defective of poor sealing performance, so coal industry is in the new pipeline technical standard that draws out methane, the preferred material of the pipeline that requires to draw out methane should be selected the two anti-tubing of polyethylene, and the two anti-tubing of polyethylene are in the connection on ground, general adopt the straight tube butt joint, the electrical heating welding, and under the coal mine owing to the reason of gas, do not allow to use non-explosion-proof electrical heating to operate in the down-hole, as going into the well after the welding of ground, its length is difficult to adapt to conditions down-hole again, and pipeline all adopts the pipe nipple flange to connect so present down-hole draws out methane.
Summary of the invention;
The purpose of this utility model is exactly for overcoming above deficiency, a kind of two anti-tubing of employing PE at present that draw out methane under the coal mine that solved are provided, the big problem of pipeline butt joint difficulty, realized that pipe and flange are integrated, the cancellation steel is moulded and is used with, the mould with the two anti-material compacting flanges of polyethylene of a plastic pressure forming flange.
The technical scheme that realizes the purpose of this utility model is such, described mould with the two anti-material compacting flanges of polyethylene, its structure is that empty T shape outer mold cover (3) in the circle is set, it is characterized in that in outer mold cover (3), being provided with guide chute (2) and the real core T of a circle shape slip core rod (1) is set with outer mold cover (3) coupling, be provided with hollow flange body (5) between outer mold cover (3) and the real core T shape slip core rod of circle (1), the interior bottom of outer mold cover (3) is measured the two anti-flange material (4) of polyethylene that placement has plastified in accordance with regulations.Operation principle is that the bottom is measured the placement two anti-material of polyethylene (4) in accordance with regulations in outer mold cover (3), to justify real core T shape slip core rod (1) and insert outer mold cover (3), and alignment guide chute (2), the pressure at right angle that adds 15T-20T in the real core T shape slip core rod of circle (1) top, T shape slip core rod (1) pushed up with the interior bottom side edge of outer mold cover (3) be adjacent to, the two anti-material of polyethylene (4) that make the interior bottom of outer mold cover (3) measure placement are in accordance with regulations all clamp-oned hollow flange body (5), form the two anti-flange bodies of polyethylene.
Adopt the mould with the two anti-material compacting flanges of polyethylene of the present utility model, having solved draws out methane under the coal mine adopts the two anti-tubing of PE, the big problem of pipeline butt joint difficulty at present, realized that pipe and flange are integrated, cancelled steel and moulded and use with, alleviated deadweight, greatly facilitated transportation and install, have simple in structure, flexible to operation, labour intensity is low, good seal performance, practical and attractive generous, profitable advantage.
Description of drawings:
Accompanying drawing is the die structure dwg with the two anti-material compacting flanges of polyethylene
Among the figure: 1. justify real core T shape slip core rod, 2. guide chute, 3. outer mold cover, 4. two material, the 5. hollow flange die bodys of resisting of polyethylene.
The specific embodiment:
Below in conjunction with accompanying drawing, the utility model is described in further detail for embodiment, suppress the mould of flanges as shown in drawings with the two anti-material of polyethylene, be to adopt metal pipe material to make the empty T shape outer mold cover (3) of a cylindrical, in outer mold cover (3), be provided with the sliding altar (2) of guiding, with outer mold cover (3) coupling the real core T of a circle shape slip core rod (1) is set, between outer mold cover (3) and the real core T shape slip core rod of circle (1), be provided with hollow flange body (5), the interior bottom of outer mold cover (3) is measured in accordance with regulations and is placed the two anti-material of polyethylene (4), and the utility model adapts to and general medium-sized and small enterprises production.
Claims (2)
1. suppress the mould of flanges with the two anti-material of polyethylene, it is characterized in that being provided with the empty T shape of a circle outer mold cover (3), in outer mold cover (3), be provided with guide chute (2), with outer mold cover (3) coupling the real core T of a circle shape slip core rod (1) is set, between outer mold cover (3) and the real core T shape slip core rod of circle (1), is provided with hollow flange body (5).
2. the mould of the two anti-material compacting flanges of polyethylene as claimed in claim 1 is characterized in that the bottom is measured the placement plastic cement two anti-material of polyethylene (4) in accordance with regulations in outer mold cover (3).
