Abstract
The utility model relates to the technical field of notebook computer production dies, and particularly discloses a novel notebook computer production die capable of improving stress shadows. An oblique jacking part, an angle pin pull rod, a straight ejector block and a straight ejector pull rod are arranged in the die, wherein one end of the angle pin pull rod is connected with a lower ejector plate, and the other end of the angle pin pull rod is connected with the oblique jacking part; one end of the straight ejector pull rod is connected with the lower ejector plate, and the other end of the straight ejector pull rod is connected with the straight ejector block. According to the novel notebook computer production die, a short angle pin structure is adopted for solving existing problems, and an ejector pin is replaced by the large straight ejector block, so that the problem of appearance stress shadows of the structural part of an ultrathin notebook computer is completely solved, the yield is improved to 96 percent according to the statistic, and good effects are achieved.
Description
Technical field
The utility model relates to notebook production technical field of mold, specifically a kind of notebook production novel die that improves stress shadow.
Background technology
Along with the day by day lightening this development trend of electronic product, notebook computer is also more and more thinner, more and more lighter, it is very thin that Laptop case part will become, wherein the structural thickness of basic housing component product also becomes ultra-thin, reach 0.8mm even thinner, when product thickness become ultra-thin after, production to mould development and moulding all has a great impact, if by traditional moulds Design Thinking, directly adopt thimble, the ejecting mechanism top products such as taper pin there will be top protruding, top prints, the problems such as stress shadow.As shown in Figure of description 1, when traditional Design of Dies, can adopt the mode of common thimble and common taper pin to eject, due to this type thimble and taper pin all long, in the time of injection and pressurize, can produce a little distortion, in cooling process, pressure in die cavity can reduce, the cooling meeting difference to some extent of the cooling and ejecting mechanism of die, cause product surface to occur stress shadow, push up the bad of the outward appearances such as seal, need by manual wipping or polishing, yield is only 81%, by analyzing material and the structure of ejecting mechanism, due to taper pin and thimble all long, directly reach ejector retainner plate, so rise and injection pressure can produce larger distortion when larger in mould temperature, and in cooling procedure because cavity pressure is less, thimble and taper pin can have rebound effect power to product face, extruding plastic cement products, plastic cement products internal structure is changed, cause stress shadow, protruding phenomenon is pushed up in serious also having.
Therefore, design the problem that can solve ultra-thin notebook structural member outward appearance stress shadow for overcoming the deficiency of above-mentioned technology, improve the yield of producing, a kind of notebook production novel die that improves stress shadow that yield has promoted according to statistics, inventor's problem to be solved just.
Summary of the invention
For the deficiencies in the prior art, the purpose of this utility model is to provide a kind of notebook production novel die that improves stress shadow, it is simple in structure, easy to use, can solve the problem of ultra-thin notebook structural member outward appearance stress shadow, improved the yield of producing, yield promotes according to statistics, has extraordinary practical value.
The utility model solves the technical scheme that its technical problem adopts: a kind of notebook production novel die that improves stress shadow, mould comprises upper mounted plate, hot runner manifold, caster, male model plate, mould pin, upper plate, lower roof plate, bottom plate, upper mounted plate bottom is connected with hot runner manifold, hot runner manifold bottom is connected with caster, bottom plate top is provided with lower roof plate, lower roof plate top is provided with upper plate, upper plate top is provided with mould pin, it is characterized in that: in mould, be provided with oblique top, taper pin pull bar, straight jacking block, straight top pull bar, taper pin pull bar one end is connected with lower roof plate, the taper pin pull bar other end is connected with oblique top, pull bar one end, straight top is connected with lower roof plate, the straight top pull bar other end is connected with straight jacking block.
Further, described taper pin pull bar is arranged in mould pin.
The beneficial effects of the utility model are:
The utility model, for above-mentioned existing problem, adopts shorter inclined pin structure, changes thimble into large straight jacking block, thoroughly solve the problem of ultra-thin notebook structural member outward appearance stress shadow, improved the yield of producing, yield has been promoted to 96% according to statistics, has extraordinary effect.

Description of reference numerals: 1-upper mounted plate; 2-hot runner manifold; 3-caster; 4-male model plate; 5-mould pin; 6-upper plate; 7-lower roof plate; 8-bottom plate; 9-product; 10-oblique top; 11-taper pin pull bar; The straight jacking block of 12-; The straight top of 13-pull bar.
Detailed description of the invention
Below in conjunction with specific embodiment, further set forth the utility model, should be understood that these embodiment are only not used in restriction scope of the present utility model for the utility model is described.In addition should be understood that those skilled in the art can make various changes or modifications the utility model after having read the content of the utility model instruction, these equivalent form of values drop on application appended claims limited range equally.
Fig. 1 is a kind of notebook production Novel die structure schematic diagram that improves stress shadow of the utility model, mould comprises upper mounted plate 1, hot runner manifold 2, caster 3, male model plate 4, mould pin 5, upper plate 6, lower roof plate 7, bottom plate 8, upper mounted plate 1 bottom is connected with hot runner manifold 2, hot runner manifold 2 bottoms are connected with caster 3, bottom plate 8 tops are provided with lower roof plate 7, lower roof plate 7 tops are provided with upper plate 6, upper plate 6 tops are provided with mould pin 5, in mould, be provided with oblique top 10, taper pin pull bar 11, straight jacking block 12, straight top pull bar 13, taper pin pull bar 11 one end are connected with lower roof plate 7, taper pin pull bar 11 other ends are connected with oblique top 10, pull bar 13 one end, straight top are connected with lower roof plate 7, straight top pull bar 13 other ends are connected with straight jacking block 12, taper pin pull bar 11 is arranged in mould pin 5.
The basis composition that upper mounted plate 1 in the utility model, hot runner manifold 2, caster 3, male model plate 4, mould pin 5, upper plate 6, lower roof plate 7, bottom plate 8 are mould bases, the length of oblique top 10 has significantly shortening, and be controlled at concordant with die bottom surface as far as possible, can reduce the distortion that product 9 injection pressures produce, originally the thimble of design now changes to the larger and shorter straight jacking block 12 of lifting surface area, and taper pin pull bar 11 directly promotes straight jacking block 12 while ejecting with straight top pull bar 13 and with oblique top 10, product ejected.Adopt shorter inclined pin structure, change thimble into large straight jacking block 12, thoroughly solve the problem of ultra-thin notebook structural member outward appearance stress shadow, improved the yield of producing, yield has been promoted to 96% according to statistics, has extraordinary effect.
