Abstract
The invention discloses a blow molding production process for a box body of a draw-bar box. The blow molding production process comprises the following production flow: (1) extruding a PC (Polycarbonate) raw material in a molten state into a box body mould of the draw-bar box from an injection molding port; (2) performing blow molding formation from the interior of the mould injection molding port of the box body of the draw-bar box, wherein the pressure of the blow molding formation is 0.6-0.8 MPa, the forming temperature of the box body of the draw-bar box is 230-260 DEG C, and the forming time of the box body of the draw-bar box is 2-3 minutes; (3) taking the blow molding formed box body of the draw-bar box out of the mould; and (4) cutting the box body of the draw-bar box. The production process provided by the invention is simple and has a short production period; particularly, the loss of the scrap of the conventional production process for the box body of the draw-bar box can be reduced by 35-40 percent; the production cost can be reduced by over 25 percent; the working efficiency is increased; the original box body production process is greatly improved and remarkably improved; and the blow molding production process is worthy of being greatly promoted in the industry.
Description
Technical field
The present invention relates to a kind of draw-bar box, relate in particular to that a kind of technology is simple, draw-bar box casing blowing production technology more than 25% reduces cost.
Background technology
The casing of existing draw-bar box all adopts plastic uptake technology that dull and stereotyped plastic uptake is become the groove-like casing; The material that groove-like casing casing port is unnecessary excises and the polishing moulding after the moulding; This just causes the waste of corner material, and cost increases, and production procedure is long; Therefore, demand urgently the production technology of draw-bar box is carried out significant improvement and raising.
Summary of the invention
The objective of the invention is to, overcome the above-mentioned defective of prior art, provide a kind of technology simple, draw-bar box casing blowing production technology more than 25% reduces cost.
For realizing said purpose, production technology provided by the invention is following: comprise following production procedure, comprise following production procedure, 1., from injection hole clamp-on draw-bar box box mold in molten condition the PC raw material; 2., blow molding in the mold injection mouth of draw-bar box casing, the pressure of said blow molding is 0.6～0.8MPa, said draw-bar box casing forming temperature is 230～260 ℃, said draw-bar box casing molding time 2～3 minutes; 3., the draw-bar box casing with blow molding takes out in mould; 4., the draw-bar box casing is cut.
Said PC raw material can be used the PET raw material substitution.
The usefulness of patent of the present invention is; Production technology is simple, and is with short production cycle, particularly can reduce the loss 35～40% of rim charge of the casing production technology of traditional draw-bar box; Can reduce production costs more than 25%; Improved operating efficiency, original casing production technology is had significant improvement and significantly improves, worth industry is widelyd popularize.
The specific embodiment
Embodiment 1:
Comprise following production procedure, 1., from injection hole clamp-on draw-bar box box mold in molten condition the PC raw material; 2., blow molding in the mold injection mouth of draw-bar box casing, the pressure of said blow molding is 0.6～0.8MPa, said draw-bar box casing forming temperature is 230～260 ℃, said draw-bar box casing molding time 2～3 minutes; 3., the draw-bar box casing with blow molding takes out in mould; 4., the draw-bar box casing is cut.
Embodiment 2:
Comprise following production procedure, 1., from injection hole clamp-on draw-bar box box mold in molten condition the PET raw material; 2., blow molding in the mold injection mouth of draw-bar box casing, the pressure of said blow molding is 0.6～0.8MPa, said draw-bar box casing forming temperature is 230～260 ℃, said draw-bar box casing molding time 2～3 minutes; 3., the draw-bar box casing with blow molding takes out in mould; 4., the draw-bar box casing is cut.
The preferred embodiment of below only giving an example, the composition that other is similar, be equal to, technology, content etc. all should belong to the protection domain of patent of the present invention.
Claims (2)
1. draw-bar box casing blowing production technology is characterized in that: comprise following production procedure, 1., from injection hole clamp-on draw-bar box box mold in molten condition the PC raw material; 2., blow molding in the mold injection mouth of draw-bar box casing, the pressure of said blow molding is 0.6～0.8MPa, said draw-bar box casing forming temperature is 230～260 ℃, said draw-bar box casing molding time 2～3 minutes; 3., the draw-bar box casing with blow molding takes out in mould; 4., the draw-bar box casing is cut.
