Abstract

A tub moulded die is advanced on mandrel vibration technology flexible joint steel bell and spigot top relates to a mould. Including bellmouth shaping ring, socket shaping ring, socket chassis, socket shaping ring and socket detachable connection of chassis, the outer edge on socket shaping ring sum socket chassis sets up the flange that the round was gone out respectively, sets up the tapering pinhole of eight at least equipartitions on the flange on socket shaping ring sum socket chassis, and the tapering pinhole one -to -one on socket shaping ring sum socket chassis sets up the tapering round pin in the tapering pinhole that each group corresponds, and the terminal surface of tapering round pin does not project the free terminal surface of flange, set up three radial pinhole on socket shaping ring, three radial pinhole respectively with the drain pipe socket that will cast on pressure testing water injection pore pair answer. This mould makes that the drawing of patterns is simple, the shaping of casting body is effectual.

Description

Core Vibrated Casting Process flexible joint steel bell and spigot jacking tube shaping mould

Technical field

The utility model relates to a kind of mould, particularly a kind of manufacturing technology field of jacking tube bell and spigot shaping mould.

Background technology

Bian Ding is dug with jack in component limit by jacking construction exactly, and top is to desired location.Only have when being inconvenient to excavate and just can adopt this construction method.

Jacking construction drainpipe is cast by concrete, its two sections is bellmouth and socket respectively, during casting, bellmouth shaping dies and socket mould need be used, socket mould is made up of the socket forming ring be wholely set and socket chassis, this socket shaping mould, in knockout course, makes demoulding difficulty, and easily produces heeling error; In casting cycle, this socket shaping mould can not ensure the concentricity of bell and spigot.

Its socket circumference of jacking-type drainpipe generally arranges three pressure testing inlet openings, in casting cycle, often has sewage, earth to infiltrate wherein, makes it block.

Utility model content

In order to overcome above-mentioned defect, the utility model provides a kind of Core Vibrated Casting Process flexible joint steel bell and spigot jacking tube shaping mould.

The utility model comprises bellmouth forming ring, socket forming ring, socket chassis, described socket forming ring is connected with described socket chassis is detachable, the outer on described socket forming ring and socket chassis arranges the flange that a circle is gone out respectively, the described flange on socket forming ring and socket chassis arranges at least eight uniform tapering pin-and-holes, the tapering pin-and-hole one_to_one corresponding on described socket forming ring and socket chassis, arrange taper pin in each group of corresponding described tapering pin-and-hole, the end face of described taper pin does not protrude the free end face of described flange; Described socket forming ring arranges three radial pin-and-holes, and described three radial pin-and-holes are corresponding with the pressure testing water injection hole on the drainpipe socket that will cast respectively.

In use, coordinate the inside and outside mould of drainpipe to use, external mold lower end is connected to socket forming ring flange upper end to the utility model, and internal mold is connected on socket chassis; After socket forming ring and steel socket fix, radial pin-and-hole on socket forming ring is corresponding with the pressure testing inlet opening on steel socket to be communicated with, insert pin, pin is inserted in pressure testing inlet opening always, like this when casting, can ensure that socket forming ring rotates or play, ensure that and build rear bell and spigot concentricity, ensure that the quality of product, good forming effect; In addition, owing to being fixed by cone pin between socket forming ring and socket chassis, when the adventitia demoulding, directly take off socket chassis, then outwards extract pin, after pin departs from socket, socket forming ring is communicated with external mold and can easily takes off.

Socket forming ring described in the utility model is an annular trough body, and the notch of described annular trough body is towards described socket chassis; This set can facilitate the plug of pin in described pin-and-hole.

The utility model arranges seal groove respectively on the inside and outside sidewall of described socket forming ring, and for the circle that is filled with a sealing, described seal groove is separately positioned on the sidewall away from an end on described socket chassis; Fitted seal circle casting in seal groove, can prevent sewage, silt from infiltrating jack part, avoids the blocking of pressure testing inlet opening, namely ensure that product quality.

Accompanying drawing explanation

Fig. 1 is a kind of structural representation of the present utility model;

Fig. 2 is the A portion enlarged drawing in Fig. 1.

Detailed description of the invention

As shown in Figure 1, this Core Vibrated Casting Process flexible joint steel bell and spigot jacking tube shaping mould, comprise bellmouth forming ring 1, socket forming ring 2, socket chassis 3, socket forming ring 2 is connected with socket chassis 3 is detachable, the outer on socket forming ring 2 and socket chassis 3 arranges the flange 4 that a circle is gone out respectively, the flange 4 on socket forming ring 2 and socket chassis 3 arranges at least eight uniform tapering pin-and-holes 5, tapering pin-and-hole 5 one_to_one corresponding on socket forming ring 2 and socket chassis 3, in each group of corresponding tapering pin-and-hole 5, taper pin 6 is set, the end face of taper pin 6 does not protrude the free end face of flange 4, socket forming ring 2 arranges three radial pin-and-holes, 7, three radial pin-and-holes 7 corresponding with the pressure testing water injection hole on the drainpipe socket that will cast respectively.Socket forming ring 2 is an annular trough body 8, and the notch of annular trough body 8 is towards described socket chassis 3; The annular trough body 8 and plug that can facilitate pin in pin-and-hole is set with the split type of socket chassis 3.

Further, the inside and outside sidewall of socket forming ring 2 arranges seal groove 9,10 respectively, for the circle that is filled with a sealing, seal groove 9,10 is separately positioned on the sidewall away from an end on socket chassis 3.
