The specific embodiment

The utility model is applicable to for example common apparatus of domestic production plastic pipe such as fluid pressure type plastic-injection moulding machine, its structure such as Fig. 1 are to shown in Figure 5: be made up of A mould and B mould, two moulds all have die and punch, and die is provided with steam vent 11 and the injecting hole 12 that is communicated with its inner chamber.Described punch is provided with the ring flange 14 that connects die; Ring flange is close to the entrance point edge of die, is linked to each other by bolt.Described die, be evenly distributed with some cyclic reinforcing rib groove 3 on its internal chamber wall, one end of its inner chamber is provided with the bellmouth inner chamber 2 that constitutes punch bellmouth shoulder 16, the other end is provided with the ring-type seam 7 that closely links to each other with body 17 end faces of punch, and the other end of B mould die inner chamber also is provided with o-ring groove 13.

See Fig. 1 and Fig. 2: process the bigger water drainage plastics pipe that is used for city-building for convenience, the die of above-mentioned A mould and B mould can be made up of two identical little moulds.Concrete structure is: die can be made up of the semicircle concave dies of two identical 180 degree, and it is divided into two vertically by die and forms, and its axial edge that closes up the place is provided with several bolts hole 9 by the hexagon socket head cap screw connection.Therefore:, and then take out " the modified and reinforced pressure water pipe of regenerating polypropylene " of moulding in the die as long as after pulling down hexagon socket head cap screw on the axial edge, die integral body can be separated, and is convenient to extract out the punch of A mould or B

mould.Sequence number

5 and 6 is respectively the inwall of groove, die among the figure.

Certainly, process the bigger water drainage plastics pipe that is used for city-building for convenience, the die of above-mentioned A mould and B mould can be made up of four identical little moulds.Promptly on the basis of aforementioned per half concave die, it is split into two identical smaller part concave dies along laterally being divided into two again, i.e. first smaller part concave die 10 and second smaller part concave die 8; At the place that closes up that bayonet socket is arranged of two identical smaller part concave dies, its widthwise edge is along the fastening screw keyhole 4 of several hexagon socket head cap screws that are provided with several available hexagon socket head cap screw series connection; During assembling, through hexagon socket head cap screw fastening aforementioned 180 the degree semicircle dies (half sheet concave die).Then two and half sheet concave dies are closed up, and by several hexagon socket head cap screws bolt hole 9 of connecting one by one, fastening back forms the assembling of whole die as shown in Figure 5.The side face of die is provided with some the equally distributed ring-type convex tendons 22 of strengthening the effect of critical external compressive resistance power that play.

See Fig. 3: the punch of A mould can be made up of the ring flange 14 and the die body that combine as a whole.Die body is made up of the bellmouth end 15 that has taper, bellmouth shoulder 16, body 17 and the tail pipe 19 that are arranged in order, and stepped, they all have tapering.Ring flange 14 combines as a whole with bellmouth end 15, and ring flange 14 is provided with several bolts hole 20.

See Fig. 4: the punch of B mould is made up of the ring flange 14 and the die body that combine as a whole; Die body is made up of the bellmouth end shoulder 21, bellmouth shoulder 16, body 17 and the tail pipe 19 that are arranged in order, and stepped, they all have tapering; Ring flange 14 combines as a whole with bellmouth end shoulder 21, and ring flange 14 is provided with several bolts hole 20.

In order to alleviate the weight of punch, the punch in this example has inner chamber 18 (seeing Fig. 3 and Fig. 4).

The punch of A mould, its tail pipe external diameter has the bellmouth internal diameter of seal groove die 13 by equaling gradually greatly to 3 millimeters (pipe diameter is 0.2 meter-1.5 meters) than B die strip bellmouth and socket.Because it utilizes the principle of the performance of expanding with heat and contract with cold (13 ‰-15 ‰) of plastics, do a collection of A mould pipe earlier, allow it cool off naturally, do B mould pipe again, after the demoulding of B mould pipe, immediately the tail pipe of cooled A mould pipe is inserted in the bellmouth of B mould pipe, so big external diameter tail pipe also can be inserted into equal and less than socket pipe in, at this moment A mould pipe and B mould pipe be connected to become 2 meter 1 the joint homogeneous tube.Be guaranteed through the mechanical strength of junction, cooling back naturally, use welding rod with material through electric heating processing along circumference the B mould tube faucet end surface side of A mould pipe and B mould pipe junction again, A mould pipe and B mould pipe are welded to reach seal impermeable purpose.

The bad shape seam 7 of above-mentioned die, its effect is: enter the inner chamber of die when the punch die body after, the one, punch is located in the die inner chamber; The 2nd, can make ring flange 14 be close to the inlet end face of die, again by the bolt hole 20 of several bolts above several hexagon socket head cap screws polyphone punch ring flange 14, with several the threaded bolts hole 1 and fastening above the die inlet end face, thereby punch is fixed; The 3rd, in the piston head vertical depression by the fluid pressure type plastic-injection moulding machine arrives the material cylinder, grog when the material of punishment in advance cylinder is chewed the injecting hole 12 that is communicated with its die inner chamber and is injected into the die inner chamber, can be prevented that grog from leaking out grog from the tail pipe 19 of die inlet end face and punch.

The drainpipe that comes out by the utility model A mould and B Mould Machining, behind its socket joint, the socket joint position is tightly connected by welding manner, and constituting an end thus has bellmouth, the other end that a drainpipe of socket (band seal groove) is arranged, and this drainpipe can be used for cities and towns discharging rainwater or sewage.
