The utility model includes a hollow tube body with a flange end; two gaskets, a spring, an anti-loosing gasket and a squeezing piece are sheathed on the tube body by being close to the flange head in turn; a seal gel ring is also arranged between the two gaskets; the spring is a left-hand spring; the surface of the anti-loosing gasket contacted with the spring is provided with a right-angle gear; the surface contacted with the squeezing piece is provided with an isoceles gear; the waist of the squeezing piece is provided with a thread; one side of the squeezing piece is provided with a right-angle gear which is matched with the anti-loosing gasket; the other side is provided with a handwheel; when in use, the connection-seal component connected with a soft water tube is inserted into a matched cooling water and screwed; the expansion seal principle of the seal gel ring is utilized; an adhesive plaster needing not to be sealed is adopted; the connection-seal component is conveniently assembled and disassembled; the spring is arranged which can broaden the size tolerance of the component; the anti-loosing gasket can prevent the squeezing piece from loosing; the integral structure of the connection-seal component is compact; besides, the connection-seal component is conveniently used and has a good seal effect.

Description

The black box of plugging into

Technical field

The utility model relates to a kind of black box of plugging into, and relates in particular to a kind of black box of plugging into that is used for the injection mould cooling nozzle.

Background technique

In injection moulding die trial stage or production phase, the time regular meeting installation or removal mould on injection machine, and will remove or be communicated with cooling water channel on the mould accordingly.Plug into method and the existing method of plugging into by traditional mold cools down water hole all can not be satisfactory, their common characteristic are all will do sealing with the screw thread place that the sealing adhesive plaster is entangled in pipe end, then body is screwed into the corresponding cooling water hole of mould, the consume material of so not only losing time can't guarantee sealing effect.Also have and carry out perfect connecting assembly on this principle, the piece though they are plugged into still can't break away from the sealing adhesive plaster, and complex structure, volume be big, remove relatively difficulty, and volume greatly also makes the often difficult position of arranging when designing mould.

The model utility content

The utility model need use the sealing adhesive plaster in order to solve the existing black box of plugging into, sealing effect is not good, the shortcoming of installing/dismounting trouble, a kind of black box of plugging into is provided, and it need not to seal adhesive plaster and can realize quick mounting and dismounting, and can reach good sealing effect.

For solving the problems of the technologies described above, the utility model adopts following technological scheme: a kind of black box of plugging into, it comprises that one has the hollow body of flange head, on body, be close to flange head and be with two pads, spring, check washer and extrusion successively, also be provided with an O-ring seal between two pads.

Described spring is a left-handed spring, and the one side that check washer contacts with spring has the right angle tooth, and the one side that contacts with extrusion has the isosceles tooth.Be threaded at the extrusion waist, extrusion one side has the isosceles tooth that is complementary with check washer, and opposite side has handwheel.

Described each parts abut flange headgear on body after, the body the other end extends to outside the extrusion.

The screw thread of described extrusion waist is an outside thread, and minor diameter of thread is respectively greater than the external diameter of check washer, spring, pad and body upper flange head.

At threaded coaxial aperture in big slightly upper end of the cooling water hole place of mould processing, cooling water hole and coaxial aperture joint form a level, and the screw thread of coaxial aperture upper end and the screw thread of extrusion are complementary.During use, the black box of originally plugging into that has connected hose inserted to tighten get final product.O-ring seal plays sealing effect by the expansion that takes place under the extruding of two pads.

The utility model utilizes O-ring seal expansion principle, the black box one design of adopting of plugging into, need not to seal adhesive plaster, assembling, dismounting are fast, be provided with spring and can relax the size of components tolerance, have check washer and can prevent that extrusion is loosening, the black box compact overall structure of plugging into, easy to use, good sealing effect.

Description of drawings

Below in conjunction with embodiment and accompanying drawing the utility model is described further:

Fig. 1 is the utility model erection drawing;

Fig. 2 uses schematic representation for the utility model.

Embodiment

As Fig. 1 black box of plugging into shown in Figure 2, it comprises that a left end has the hollow body 1 of flange head, is with successively from left to right on body between two pads 2, spring 4, check washer 5 and extrusion 6, two pads 2 and is provided with an O-ring seal 3.Described spring 4 is a left-handed spring, and the one side that check washer 5 left sides contact with spring 4 has right angle tooth 7, and the one side that the right side contacts with extrusion 6 has isosceles tooth 8.The right side tail end of spring 4 and the straight-sided flank near normal of right angle tooth 7 stop check washer 5 reverse loose purposes of changeing thereby spring 4 is played.Be threaded 9 at extrusion 6 waists, the left side has the isosceles tooth that is complementary with check washer 5, and the right side has handwheel 10.Described each parts abut flange headgear on body 1 after, body 1 right-hand member exposes outside the extrusion 6, so that water pipe is installed.The screw thread 9 of described extrusion 6 waists is an outside thread, and screw thread 9 internal diameters are respectively greater than the external diameter of check washer 5, spring 4, pad 2 and body upper flange head.

As shown in Figure 2, need process a coaxial aperture in cooling water channel 12 positions of using the black box mould 11 of originally plugging into, be Spielpassung between coaxial aperture and pad 2 and the check washer 5.The coaxial aperture aperture forms a level greater than cooling water channel 12 diameters at surface of contact.The band internal thread of coaxial aperture outer end, the screw thread 9 of internal thread and extrusion 6 is complementary.During use, body 1 right-hand member is connected hose, the black box of will plugging into inserts in the mould 11 corresponding holes, tightens extrusion 6 by handwheel 10, and pressure is delivered to O-ring seal 3 from extrusion by check washer 5, spring 4 and pad 2.The flange of body 1 left end is subjected to stopping of stepped shaft level at the bottom of the hole on the other hand, produces an opposite effect power and is delivered on the O-ring seal 3.After O-ring seal 3 is subjected to two power extruding in opposite directions, make its radial deformation expansion, but the outer rim of O-ring seal 3 and inner edge are stopped by the hole wall of mould 12 and body 1 outer wall respectively, so O-ring seal 3 can produce extruding force to the hole wall and the body 1 of mould 12 at this moment, thereby reach sealing effect.

O-ring seal 3 can not influence the working life of cushion rubber at the geometric distortion of an approximate sealing.Also very convenient when dismounting, the extrusion 6 of only need back-outing, the whole black box of plugging into just separates with mould 11., needn't remove at every turn and install because but extrusion 6 can be connected on the body 1 for a long time with body 1 slide relative event water pipe.Left-handed spring 4 cooperates with check washer 5, extrusion 6 easily is screwed into is difficult for unclamping, and the effect of spring 4 simultaneously also is beneficial to the tolerance of suitably relaxing hole depth.
