Technical field
The present invention relates to the blowing processing technique field, relate in particular to a kind of container style that is applied to and strengthen the processing technology of the required plastics inner bag of pressure vessel etc. as making glass fibre.The invention still further relates to the particular manufacturing craft of aforementioned processing technology.
Background technology
As shown in Figure 1, in the existing plastics inner bag contour machining procedure, constitute the blow needle assembly by blow needle 40, screw thread mold insert 41, adopt mould 1,2 matched moulds to make material base 5 form the inner bag of setting shape.Otch circle 11,21 outside on mould 1,2, including respectively (or being the outer otch circle portion on the mould).Because outer otch circle 11,21 is along with mould 1,2 also is divided into left and right two parts, cause on the end face 3 of inner bag after the moulding one piece line 30 (referring to shown in Figure 2) being arranged.The existence of this piece line 30 influences end face 3 sealing effectiveness in use, must adopt this piece line 30 on the cutting step removal end face 3 in road, back processing technology, is used as sealing surface in order to obtain a smooth end face.In addition, also have the control valve of some follow-up assemblings need adopt the chamfering sealing simultaneously, so also need to form a chamfering 31 corresponding, that have sealing function (as shown in Figure 3) on the inner bag after the moulding.
The following process at above piece line 30, chamfering 31 places all needs to drop into extra artificial, time and process equipment.And because problems such as machining accuracy also may produce inhomogeneous chamfering, can cause the goods seal failure when serious, reduced yields.
Therefore those skilled in the art is devoted to develop the blowing processing technology of the container body that a kind of technology is simple, yields is high always.
Summary of the invention
The technical problem to be solved in the present invention is many in order to overcome the prior art manufacturing procedure, and the shortcoming that yields is low provides the blowing processing technology of the container body that a kind of technology is simple, yields is high.
The present invention solves above-mentioned technical problem by following technical proposals: the invention provides a kind of blowing processing technology of container body, may further comprise the steps at least:
Preferably, described interior otch circle is smooth end face towards an end of described screw thread mold insert.
Preferably, described interior otch circle has the chamfering flange towards an end of described screw thread mold insert.
Preferably, described blow needle assembly is set on the described blow needle slidably by otch circle in described, and then described screw thread mold insert is twisted on the screw thread that is located at described blow needle form.
Preferably, after the described step 4, mould is separated after reaching molding time, described screw thread mold insert and the described container bodily form in the described blow needle assembly are integral.Further, at last described blow needle is back-outed, described interior otch circle comes off simultaneously in described container body.
Preferably, described step 4 makes described material base pressurized form the shape of design by discharging gases at high pressure.
Positive progressive effect of the present invention is: processing technology of the present invention is owing to adopted brand-new blow needle assembly, utilize the interior otch coil structures that increases newly in this blow needle assembly, the container body that obtains has level and smooth sealing plane and sealing chamfering, need not any processing and can satisfy finished product to the requirement of plane and chamfering, avoided because the asymmetric problem of chamfering that does not steadily cause of smear metal processing.Therefore processing technology of the present invention has improved production efficiency, has improved product quality.
The present invention also provides a kind of container body blowing processing technology particular manufacturing craft, comprises first mold, second mold of joining work mutually, also comprises the blow needle assembly; Described blow needle assembly comprises interior otch circle, blow needle and screw thread mold insert; The otch circle is set on the described blow needle slidably in described, and described screw thread mold insert is twisted and is located on the screw thread of described blow needle.
Preferably, described interior otch circle is smooth end face towards an end of described screw thread mold insert.
Preferably, described interior otch circle has the chamfering flange towards an end of described screw thread mold insert.
The present invention was located at interior otch snare on the blow needle earlier before being screwed in the screw thread mold insert on the blow needle by setting up an integrally-built interior otch circle, relied on the step on the blow needle that interior otch is drawn a circle to approve the position on the position of setting.Blow needle can freely move up and down in interior otch circle.Along with blowing out of gases at high pressure, finally obtain the plastics inner bag that needs.Particular manufacturing craft of the present invention has solved container body such as the back processing problems of inner bag after moulding that blowing forms, and the container body of acquisition has level and smooth sealing plane and sealing chamfering, need not any processing and can satisfy finished product to the requirement of plane and chamfering.
