Abstract
The utility model provides a needle blowing rod for a blowing machine. The needle blowing rod for the blowing machine comprises a rod outer shell, a core rod, a protective cover and a material cutting ring, and is characterized in that the rod outer shell, the core rod, the protective cover and the material cutting ring are arranged in a split mode, the rod outer shell is connected with the material cutting ring through threads, the protective cover is connected in a connection position between the material cutting ring and the rod outer shell in a sleeved mode, the front end and the tail end of the core rod are respectively provided with sealing rings which are matched with the material cutting ring and the rod outer shell, the core rod is arranged in the rod outer shell, a cooling cavity is formed between the core rod and the rod outer shell, and a water inlet and a water outlet communicated with the cooling cavity are arranged in the side wall of the rod outer shell. The needle blowing rod for the blowing machine is small in investment, is delicate in design, and effectively improves the safety and practical applicability of equipment, thereby lowering the production cost and improving the economic benefits.
Description
Technical field
The utility model belongs to the apparatus for blow moulding field, relates in particular to a kind of blow needle bar.
Background technology
At present, in blow moulding machine, the blow needle bar adopts mostly that global design is integrally manufactured to be formed.In blow moulding machine, the blow needle bar is generally directly to be fixed on Connection Block, is driven its lifting and is blown for plastic foil and make staving by lowering or hoisting gear.In use procedure, because the blow needle bar contacts with the high temperature parison for a long time, make blow needle bar heat conduction excess Temperature, if the bung that can not get in time lowering the temperature very easily produces distortion, affect product quality.And due to blow needle bar blank ring portion position long-term with the contact friction of mould buckle, its periphery easily produces flash, causes the bung end face uneven, need be with blow needle bar integral demounting during the maintenance of blank ring, troublesome poeration, consuming time longer.In case the blank ring damages, need to change whole blow needle bar, cause wastage of material.
Summary of the invention
in order to solve the problems of the technologies described above, the utility model provides a kind of blow moulding machine blow needle bar, comprise the bar shell, core bar, sheath, the blank ring, it is characterized in that described bar shell, core bar, sheath and blank ring adopt the split design, described bar shell is connected with the blank ring by screw thread, described sheath is socketed in blank ring and bar shell junction, the front end of described core bar and tail end are respectively equipped with the sealing ring that matches with blank ring and bar shell, core bar is arranged in the bar shell, form cooling chamber between core bar and bar shell, be provided with the water inlet and the delivery port that are communicated with cooling chamber on the sidewall of bar shell.
The beneficial effects of the utility model are: blow needle bar each several part is adopted the split design, be convenient to the part that breaks down is carried out detachable maintaining, reduced equipment debugging man-hour and raw-material waste; Between blow needle bar shell and core bar, cooling chamber is set, can makes cooling water realize airtight waterway circulating in blowing bar integral body, avoid bulk temperature too high, affect product quality.The utility model small investment, the design ingenious, effectively improved security and the practicality of equipment, thereby reduced production cost, improved economic benefit.
Description of drawings
Fig. 1 is structural representation of the present utility model.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further explained explanation.In Fig. 1,1-bar shell, 2-core bar, 3-sheath, 4-blank ring, 5-sealing ring, 6-cooling chamber, 7-water inlet, 8-delivery port, 9-screw thread.
Bar shell 1, core bar 2, sheath 3 and blank ring 4 all adopt the split design, bar shell 1 is connected with blank ring 4 by screw thread 9, sheath 3 is socketed in blank ring 4 and bar shell 1 junction, the front end of core bar 2 and tail end are respectively equipped with the sealing ring 5 that matches with blank ring 4 and bar shell 1, core bar 2 is arranged in bar shell 1, form cooling chamber 6 between core bar 2 and bar shell 1, be provided with the water inlet 7 and the delivery port 8 that are communicated with cooling chamber 6 on the sidewall of bar shell 1.
Assembling process of the present utility model is: core bar 2 front ends are inserted in the circular hole of blank ring 4, then sheath 3 is set on blank ring 4, at the circular hole outward turning upper boom shell 1 of blank ring 4.
When the utility model uses: at first with the integral installation of blow needle bar on the blow moulding machine Connection Block, adjust the blow needle bar and be in the operating position; When blowing bucket work, water inlet 7 is connected with extraneous cooling water source, opens cooling water circulation, cooling water is interior mobile to carry out cooling to the blow needle bar at cooling chamber 6.
Above embodiment of the present utility model is had been described in detail, but described content is only preferred embodiment of the present utility model, can not be considered to be used to limiting practical range of the present utility model.All equalizations of doing according to the utility model application range change and improve etc., within all should still belonging to patent covering scope of the present utility model.
