Abstract
The invention relates to a method for shortening molding cycle of a paper holder of a copier. The method comprises the following steps: (1) adopting three-stage mold clamping force to ensure the product to be free of burrs and prolong the service lives of tie bars, toggles and templates of molds and injection molding machines; (2) adopting four-stage injection speed to avoid the product from having bubbles; (3) setting two-stage holding time to ensure the weight of the product; (4) setting appropriate material temperature and water lines (6 groups for the front mold and 7 groups for the rear mold) and lowering the mold temperature to shorten the cooling time of the mold from 30s to 18s; (5) setting 10 hot runners and four-stage injection pressure to avoid the product from deforming; and (6) charging while cooling, opening and closing the mold and even holding, ejecting multiple times while opening the mold and carrying out last ejecting and withdrawing while closing the mold. The method effectively solves the following technical problems: the 500*560*155mm products are not deformed, have normal surfaces and dispense with secondary processing during production, and the molding cycle is 38s so as to achieve the output of 68000 single molds per month.
Description
Technical field
The present invention relates to the method that a kind of paper holder of copier molding cycle shortens.
Background technology
Known injection molding cycle refers to begin to comprise by matched moulds, injection, pressurize, cooling and die sinking required time till the matched moulds next time from matched moulds.Matched moulds generally is divided into four sections: fast matched moulds, matched moulds, low pressure are protected mould and high-voltage lock mould at a slow speed.Die sinking generally is divided into three sections: it is slow that die sinking one slowly, die sinking reaches die sinking two fast.In molding cycle, in order to shorten injection molding cycle, generally to shorten moulding cool time.But in many cases, prolong moulding cool time in order to improve product deformation, and cause injection molding cycle long.Should avoid product deformation, shorten moulding cool time again, then difficulty relatively.
Summary of the invention
The technical problem to be solved in the present invention provides a kind of smooth and easy, surperficial flawless/albefaction/requirements such as burr/starved of guaranteeing that 500 * 560 * 155mm product is indeformable, 1 over thousands of size conforms drawing requires, logical paper slides, need not secondary operations during production and manually sort, to reach every month 68000 output of single mold, production efficiency has improved 45%, energy consumption has reduced by 20%, has reduced the method for the paper holder of copier molding cycle shortening of the unit cost of production.
In order to solve the problems of the technologies described above, the special character of the method that the paper holder of copier molding cycle that the present invention proposes shortens is:
1, adopts the clamp force of " locked mode (a section) 75, locked mode (two sections) 70, locked mode (five sections) 146 ", guarantee not burr of goods, prolong the service life of pull bar, toggle and the template of mould, injection machine.
2, use the injection speed of " penetrate (one) 85, penetrate (two) 95, penetrate (three) 75, penetrate (four) 65 ", avoid goods to produce bubble.
The dwell time of " pressurize () 1 second, pressurize (two) 2 seconds " 3, is set, guarantees the weight of goods.
4, barrel temperature is provided with 70 degree, and front mould is provided with 6 groups of machine water, and back mould is provided with 4 groups and freezes water, 3 groups of machine water, reduces mold temperature, makes mold cooling time shorten to 18 seconds from 30 seconds.
5, the hot flow path that 10 purts are chewed is set, reduces injection pressure, promptly penetrate (one) 120, penetrate (two) 125, penetrate (three) 120, penetrate (four) 110, avoid product deformation.
6, feed in raw material at " cool time " and folding mould even carry out simultaneously during in pressurize; Repeatedly eject when die sinking and carry out simultaneously; Last top is moved back when matched moulds and is carried out simultaneously, to shorten cycle time.
The present invention compares with conventional art and has the following advantages: injection molding cycle foreshortened to 38 seconds by original 65 seconds, each product need not secondary operations and manually sorts during volume production, to reach every month 68000 output of single mold, production efficiency has improved 45%, energy consumption has reduced by 20%, has reduced the unit cost of production.

The specific embodiment
Below in conjunction with embodiment the present invention is further described:
The method that described paper holder of copier molding cycle shortens comprises:
1, adopts the clamp force of " locked mode (a section) 75, locked mode (two sections) 70, locked mode (five sections) 146 ", guarantee not burr of goods, prolong the service life of pull bar, toggle and the template of mould, injection machine.
2, use the injection speed of " penetrate (one) 85, penetrate (two) 95, penetrate (three) 75, penetrate (four) 65 ", avoid goods to produce bubble.
3, the dwell time of " pressurize () 1 second, pressurize (two) 2 seconds " and relevant parameter (seeing following parameter list for details) are set, guarantee the weight of goods.
4, barrel temperature is provided with 70 degree, and front mould is provided with 6 groups of machine water, and back mould is provided with 4 groups and freezes water, 3 groups of machine water (seeing following parameter list and accompanying drawing for details), reduces mold temperature, makes mold cooling time shorten to 18 seconds from 30 seconds.
5, the hot flow path that 10 purts are chewed is set, reduces injection pressure, promptly penetrate (one) 120, penetrate (two) 125,
6, feed in raw material at " cool time " and folding mould even carry out simultaneously during in pressurize; Repeatedly eject when die sinking and carry out simultaneously; Last top is moved back when matched moulds and is carried out simultaneously, to shorten cycle time.
The molding technique parameter that other is associated:
The above only is preferred embodiment of the present invention, and all equalizations of being done according to claim scope of the present invention change and modify, and all should belong to the covering scope of claim of the present invention.
