Abstract
The utility model discloses a rigid joint plain-end drain pipe forming mould, belongs to the forming technologies, and aims to achieve the purpose that a mould pipe of the forming mould can be used as a mould pipe of a flexible joint C-shaped steel bell-end drain pipe. The rigid joint plain-end drain pipe forming mould adopts the technical scheme that the rigid joint plain-end drain pipe forming mould comprises the mould pipe, a left sealing head ring and a right sealing head ring, holes at the right end of the mould pipe are four step-shaped holes, the peripheral surface of the right sealing head ring is provided with four step-shaped cylindrical surfaces which are matched with the four step-shaped hole surfaces at the right end of the mould pipe, and the inner end surface of the right sealing head ring is opposite to the inner end surface of the left sealing head ring. The rigid joint plain-end drain pipe forming mould is used for forming concrete drain pipes.
Description
Technical field:
The utility model relates to a kind of pipe of cement finishing die, flat mouthful of drainpipe finishing die of particularly a kind of rigid joint.
Background technology:
The development in city is increasing to the discharge capacity of sewage, rainwater, drainpipe is bigger through requiring, country has issued standard (GB/T 11836-2009) to this Concrete and reinforced concrete drainage and sewer pipes, the most frequently used and concrete drain tile that consumption is maximum has three kinds in the standard: flexible joint C shaped steel bellmouth drainpipe, the flat mouthful drainpipe of rigid joint and rigid joint tongue and groove drainpipe, the length of tube of these three kinds of drainpipes is 2000mm, and the external diameter of pipe is all identical.Existing production with pipe die is that three kinds of pipe dies are produced this three kinds of drainpipes respectively, because caliber and length are all bigger, the used steel of every cover pipe die are very big, pipe die expense height, and occupied ground is big.
Summary of the invention:
The utility model purpose provides flat mouthful of drainpipe finishing die of a kind of rigid joint, and the mould pipe in this shaping mould also can be used for the mould pipe of flexible joint C shaped steel bellmouth drainpipe.The realization the technical solution of the utility model is, flat mouthful of drainpipe finishing die of a kind of rigid joint, comprise mould pipe and left and right end socket circle, it is characterized in that: the right-hand member hole of described mould pipe is four step-shaped holes, the step cylinder that the side face of described right end socket circle has four four step-shaped hole faces with mould pipe right-hand member to match, the inner face of this right end socket circle is relative with the inner face of left end socket circle.The utility model has the remarkable advantage that mould pipe versatility is good, die cost is low compared with the prior art.
Description of drawings:
Fig. 1 is that existing flexible joint C shaped steel holds drainpipe finishing die structural representation, Fig. 2 is flat mouthful of drainpipe finishing die structural representation of existing rigid joint, Fig. 3 is flat mouthful of drainpipe finishing die structural representation of rigid joint of the present utility model, Fig. 4 is a flexible joint C shaped steel bellmouth drain structure schematic diagram, and Fig. 5 is flat mouthful of drain structure schematic diagram of rigid joint.
The specific embodiment:
The utility model is in order to solve the shared problem of mould pipe in flat mouthful of drainpipe shaping mould of flexible joint C shaped steel bellmouth drainpipe and rigid joint, to the mould pipe in these two kinds of finishing dies relatively, the left end hole of the former mould pipe 2 is identical with the latter's mould pipe 5 left end holes, the end socket circle of changing left end can be formed separately above-mentioned two kinds of different drainpipes, but the inner surface structure of the right-hand member of these two kinds of mould pipes is inequality and both right end socket circles 1,4 is also inequality, for this reason, right end socket circle 4 in flat mouthful of drainpipe finishing die of existing rigid joint is replaced by right end socket circle 7 of the present utility model, the structure of this right end socket circle is, the outer peripheral face of end socket circle 7 is four step surfaces that the mould pipe right-hand member inner surface with flexible joint C shaped steel bellmouth drainpipe matches, the annular end face of its right-hand member is relative with left end socket circle 6, at this moment, distance between the inner face of left and right sides end socket circle should remain 2000mm, for the length of the mould pipe 2 that makes flexible joint C shaped steel bellmouth drainpipe shaping mould also can be used for flat mouthful of drainpipe finishing die of rigid joint of the present utility model, its length suitably need be extended, generally within the 50mm scope, can meet the demands, when formed flexible joint C shaped steel bellmouth drainpipe, axial length to the left end socket circle 3 of finishing die correspondingly extends, and the length that both increased is identical.
Claims (1)
1. a mouthful drainpipe finishing die is put down in a rigid joint, comprise mould pipe and left and right end socket circle, it is characterized in that: the right-hand member hole of described mould pipe is four step-shaped holes, the step cylinder that the side face of described right end socket circle has four four step-shaped hole faces with mould pipe right-hand member to match, the inner face of this right end socket circle is relative with the inner face of left end socket circle.
