Description

The fast Quick connecting joint of unthreaded hole

Technical field

The utility model relates to a kind of fast Quick connecting joint of unthreaded hole that connects with the gateway of unthreaded hole that fluid seepage detects that is applied to, and especially is applied to the fast Quick connecting joint of unthreaded hole in mold cools down water route.

Background technology

In order to control mold temperature, temperature is remained in certain scope, the mould design has the cooling duct.For the mould that the mold insert assembly unit is arranged in the template, the cooling duct is crossed over two or more mould parts usually.Cooling water channel in the mould on existing each mold insert is unthreaded hole, in order to allow the cooling duct in the mold insert form the loop, uses plug and blocks some water hole.Cooling water channel on the mold insert communicates with inlet opening and apopore on the template, and cooling water hole on the mold insert and the water hole intersection on the template seal by O-ring seal, inlet opening on the template and apopore have can with the internal thread hole of water inlet or water out adapter wire connection.After mould is carried out, must carry out the leak detection of cooling water channel.The leak detection in present mold cools down water route is normally with after the mold insert of mould and the formwork integral assembling, connect with the inlet opening and the apopore of mould by screw thread with warter connection, water inlet pipe and rising pipe and warter connection join, and then chilled water are imported the mold cools down water route and carry out the leakproof test.For, the complicated die large-scale for majority, all be to be assemblied to form by a large amount of mold inserts mostly, cooling water channel is crisscross, in case mould leaks, very difficult discovery is that the water hole plug on the inlaid piece of mould leaks or the O-ring seal place of mould parts intersection leaks.Can only integral disassembly, assembly a test again again, sometimes even want repeated disassembled and assembled, test for several times.One time that cover is large-scale, the complicated die dismounting will be taken all day for one time easily, time-consuming effort again.Therefore necessary the instrument of trying the water is improved.

Summary of the invention

The purpose of this utility model is to provide a kind of fast Quick connecting joint of unthreaded hole that can connect each mold insert unthreaded hole of mould to society, utilizes the fast Quick connecting joint of unthreaded hole to try the water separately to each mold insert.

The technical solution of the utility model is: design the fast Quick connecting joint of a kind of unthreaded hole, comprise main body, secondary seal ring, spring washer, the collar, the primary seal circle, and retaining ring, described body front end be provided with can with the screw rod of the internal thread wire connection of retaining ring perforation, main body and the face screw rod intersection are the conical surface, on described screw rod, be with secondary seal ring near the described conical surface, on secondary seal ring, be with spring washer, on described screw rod, from inside to outside be with the collar successively near spring washer, the primary seal circle, the termination wire connection of described screw rod has retaining ring, is provided with through hole in described main body.

Described retaining ring inner face extends bulge loop, and described primary seal snare is on described bulge loop.

Root at described screw rod is provided with annular groove, and described secondary seal ring is put in described annular groove.

Described coupling head also comprises the rapid-acting coupling of being with mesopore, and described rapid-acting coupling is by thread segment and described main body wire connection on it.

Use the utility model can realize that elder generation carries out leak detection to the cooling water channel of each mold insert of mould, after confirming ne-leakage, the overall package mould carries out leak detection again.Like this, leak, can find seepage place easily and repair in case find mould.So the man-hour of mould water route leak detection can be saved widely.

Embodiment

See also Fig. 1 to Fig. 3, it is the fast Quick connecting joint of a kind of unthreaded hole, comprise main body 6, secondary seal ring 5, spring washer 4, the collar 3, primary seal circle 2, reach retaining ring 1, described main body 6 front ends be provided with can with the screw rod 63 of the internal thread wire connection of the perforation 11 of retaining ring 1, the face with screw rod 63 intersections of main body 6 is the conical surface 61, root at described screw rod 63 is provided with annular groove 62, and described secondary seal ring 5 is put in described annular groove 62.Be with spring washer 4 on secondary seal ring 5, from inside to outside be with the collar 3, primary seal circle 2 successively near spring washer 4 on described screw rod 63, the termination wire connection of described screw rod 63 has retaining ring 1, is provided with through hole 64 in described main body 6.Certainly, described retaining ring 1 also can be designed to its inner face and extend bulge loop 12, and described primary seal circle 2 is enclosed within the structure on the described bulge loop 12; Also can be provided with internal projecting ring 31 on the collar 3 inwalls, the internal diameter of its internal projecting ring 31 equals the external diameter of screw rod 63, with the concentricity of assurance with main body 6.

The utility model also comprises the rapid-acting coupling 7 of being with mesopore 72, and described rapid-acting coupling 7 is by thread segment on it 71 and described main body 6 wire connections.

The effect of above-mentioned primary seal circle 2 is to prevent to leak between this unitor outer wall and unthreaded hole 81 (referring to Fig. 4) inwall, and the effect of secondary seal ring 5 is to prevent to leak between the internal thread of the perforation 11 of screw rod 63 and retaining ring 1.

See also Fig. 4, Fig. 4 is that Fig. 4 is a user mode structural representation of the present utility model.Two fast Quick connecting joints of the unthreaded hole with spline structure are inserted respectively in the water inlet and water outlet unthreaded hole 81 of mold insert 8.The fast Quick connecting joint of unthreaded hole is pressed clockwise precession, the screw thread of main body 6 and retaining ring 1 is constantly locked, because main body 6 and turn 4 contact for the conical surface 61, in the process of constantly tightening, the conical surface 61 promotes spring washer 4 distendings and unthreaded hole 81 chuckings, then water pipe is connected on rapid-acting coupling 7, can water flowing carries out leak detection.Primary seal circle 2 and secondary 5 seals, and prevents that the water in the cooling water channel from oozing out from this joint.

Utilize the fast Quick connecting joint of unthreaded hole, can be at an easy rate to the cooling water channel of mould parts independent one by one transport water leakproof test.Treat that every mould parts test finishes, overall package is tried the water again.Thereby the repeated disassembled and assembled mould when having avoided overall package to try the water seepage for the mould assembly work brings great convenience, has improved efficient, has saved the time.

The gateway that the fast Quick connecting joint of unthreaded hole also can be applicable to other field liquid state, gaseous state pipeline connects fast, carries out leak detection.
