Description
Technical field
The utility model belongs to the manufacturing technology field of practice-training teaching equipment, is specifically related to a kind of teaching with the air tube assembly of blow moulding machine.
Background technology
Teaching blow moulding machine is the Practical training equipment that structure forms and operation principle is best that training student understands plastic molding equipment, is the indispensable teaching hardwares of die & mold design and manufacture specialty and speciality of materials forming.In blow-molding process, compressed air by air tube assembly, promptly will blow in mold cavity in hot melting plastic, thus obtain blowing part under the control of pneumatic operated valve.The parts of existing installation air tube lack retaining part because of surface, cause installation and removal extremely inconvenient, particularly must by means of bench vice during installation air tube, this not only affects the installation and removal efficiency of air tube, and easily causes the surface of installing parts to damage because of the repeatedly clamping of bench vice.
Summary of the invention
The purpose of this utility model is the air tube assembly of the teaching blow moulding machine providing a kind of structure simple, reasonable in design and easy to loading and unloading, and it can solve used air tube installing component in background technology affects the technical problem of use because lacking clamp structure.
For achieving the above object, the utility model is a kind of imparts knowledge to students with the air tube assembly of blow moulding machine, it comprises mount pad, connector, air tube and sealing gasket, the upper end of described mount pad be set to cylindrical, centre is set to taper shape, lower end is provided with positive six prisms one, the cylinder of upper end is provided with external screw thread one and internal thread one, and the cylinder below described external screw thread one is provided with air inlet screwed hole; The centre of described mount pad is axially arranged with air admission hole, and described positive six prisms one are provided with internal thread two, and described internal thread two is provided with connector; The lower end of described connector is provided with positive six prisms two, and be provided with gas pin in described connector, be provided with air tube in described gas pin, the upper end of described air tube is provided with sealing gasket.
In technique scheme, described air inlet screwed hole, air admission hole communicate with the endoporus of air tube.
After adopting technique scheme, with one, spanner is clamped in positive six prism one places, another spanner is clamped in positive six prism two places, rotates arbitrary spanner, easily can install or remove air tube.So not only can shorten air tube dismounting or the time needed for installation, the surface that air tube can be protected again to install parts can not press from both sides bad, can extend the service life that air tube installs parts.
Accompanying drawing explanation
Fig. 1 is the internal structure schematic diagram of a kind of air tube assembly using blow moulding machine of imparting knowledge to students of the utility model;
Fig. 2 is the surface structure schematic diagram of a kind of air tube assembly using blow moulding machine of imparting knowledge to students of the utility model.
Respectively be designated in accompanying drawing: 1, mount pad, 11, external screw thread one, 12, air inlet screwed hole, 13, air admission hole, 14, internal thread two, 15, internal thread one, 16, positive six prisms one, 2, connector, 21, gas pin, 22, positive six prisms two, 3, air tube, 4, sealing gasket.
Detailed description of the invention
Below in conjunction with accompanying drawing, a kind of teaching of the utility model is described further with the air tube assembly of blow moulding machine:
From Fig. 1 and Fig. 2, its mount pad of the utility model 1, connector 2, air tube 3 and sealing gasket 4, the upper end of described mount pad 1 be set to cylindrical, centre is set to taper shape, lower end is provided with positive six prisms 1, the cylinder of upper end is provided with external screw thread 1 and internal thread 1, and the cylinder below described external screw thread 1 is provided with air inlet screwed hole 12; The centre of described mount pad 1 is axially arranged with air admission hole 13, and described positive six prisms 1 are provided with internal thread 2 14, and described internal thread 2 14 is provided with connector 2; The lower end of described connector 2 is provided with positive six prisms 2 22, and be provided with gas pin 21 in described connector 2, be provided with air tube 3 in described gas pin 21, the upper end of described air tube 3 is provided with sealing gasket 4.
Using method of the present utility model is, first be assembling air tube: first air tube 3 is placed in gas pin 21, sealing gasket 4 is placed on the air inlet oral area of gas pin 21, again connector 2 is installed on mount pad 1, use two spanners to clamp positive six prisms 1 and positive six prisms 2 22 respectively, can connector 1, air tube 3 be connected in aggregates with mount pad 1; Second step installs air tube assembly: be connected with the external screw thread of piston rod head by the internal thread 1 of mount pad 1, and the external screw thread 1 of mount pad 1 is connected with the internal thread of piston guide plate simultaneously, can be installed on blow moulding machine by air tube assembly; 3rd step installs inlet suction port and air induction hose: inlet suction port is arranged on air inlet screwed hole 12 place, then air induction hose is installed to the other end of inlet suction port, and adjust the aperture size of air inlet.
In the present embodiment, compressed air will be entered in air tube 3 by air induction hose, inlet suction port and air admission hole 21, then enter in the hot melting plastic of mold cavity by air tube 3, complete the of paramount importance step of blow molding.Air inlet screwed hole 12 communicates with the endoporus of air admission hole 13, air tube 3.
In blow molding, due to the straight tube internal diameter of air tube 3 lower end and external diameter unchanged, the straight tube of air tube is very easily blocked by plastics, once tracheae blocked by plastics, then air tube 3 must be unloaded from air tube assembly, the plastics disposing blocking or the air tube more renewed can work on.The utility model is that installation and removal air tube provides conveniently, and reasonable in design, anufacturability is better, and now in practical teaching, result of use is remarkable.
