Abstract
The invention discloses a mold for molding a light guide plate, and relates to a mold technique. The mold comprises a main runner for charging glue straightly, a front mold plate and a rear mold plate; a glue charge end of the main runner is communicated with an injection nozzle of an injection molding machine; a glue discharge end of the main runner is communicated with a sprue of a mold cavity; the front mold plate and the rear mold plate are arranged oppositely. The main runner for charging glue straightly is adopted so as to form main runner straight ejection and branch runner straight ejection; the runner and the glue charge are smooth, the pressure loss in the runner is very low, and the glue charge speed is high, so that the molding speed is high, the yield is high, and the manufacture cost is reduced; meanwhile, because the pressure loss in the runner is very low, a high-power injection molding machine is not required to be adopted; on one hand, the energy consumption is reduced, the equipment investment can be reduced, and the production cost of a product is reduced further; according to calculation, the manufacture cost of the light guide plate can be reduced by about 5%, and the market competitiveness is improved.
Description
Technical field
The present invention relates to mould, espespecially a kind of mould of formed light conductive plate.
Background technology
Light guide plate is the critical component of backlight, and its effect is the area source spot light of light emitting diode (being called for short LED) being changed into uniform in light emission.
Light guide plate is plastic tab, through injection mo(u)lding.It is shaped with the groove of many change light travel paths.The area of current light guide plate is general larger, and its length is more than 15 centimetres, and thickness is less than 1 millimeter, and the degree of depth of its groove is 1 ~ 10 micron.For this large area, the light guide plate of ultrathin type and shallow trench, the difficulty of its injection mo(u)lding is well imagined.
The quality of light guide plate, molding rate, yields and manufacturing cost and mould closely bound up, the shaping of light guide plate requires high to its mould.At present, the mould of formed light conductive plate has the following disadvantages:
One, runner design is unreasonable, and runner internal pressure loss is large.The runner of the mould of existing formed light conductive plate is long, and path inflection, is folded to runner from sprue.Flow channel length is large, especially inflection path, the constricted flow of melten gel certainly will be made, injection pressure loss is large, and the pressure entering die cavity reduces, and melten gel flows to die cavity and slow in the speed of mould intra-bladder instillation, its result caused: the quality of light guide plate is unstable, yields is low, and shaping speed is slow, and manufacturing cost is high.
Its two, in the situation that mould is constant, to overcome the unfavorable situation that " one " causes, the power of injection machine must be increased, improving the pressure of injection molding machine nozzle.This just needs separately to purchase powerful injection-moulding device, and increasing device drops into and equipment cost, and the energy consumption of product improves, moreover high-power injection-moulding device acquisition expenses wants more expensive than small-power injection-moulding device.
The novel die of a kind of formed light conductive plate of market demand, is not increasing the power of injection machine, utilizes existing small-power injection-moulding device to produce yields high, and shaping speed is fast, and low cost of manufacture, and the light guide plate that energy consumption is low, to improve the market competitiveness.
Summary of the invention
The technical issues that need to address of the present invention are, the mold runner design overcoming existing formed light conductive plate is unreasonable, and runner internal pressure loss is large, causes the deficiency that yields is low, shaping speed is slow, manufacturing cost is high, provides a kind of mould of formed light conductive plate.Its runner internal pressure loss is little, and light guide plate yields is high, and shaping speed is fast, and energy consumption is low.
The mould of a kind of formed light conductive plate of the present invention adopts following technical proposals:
A mould for formed light conductive plate, comprise straight enter the sprue of glue, the glue end that enters of sprue communicates with the nozzle of injection machine, and the glue-extruding end of sprue is communicated with the cast gate of die cavity.
Technique scheme is further elaborated:
Also comprise the front template and rear pattern plate that are oppositely arranged, the line of the geometric center in front template plate face and the geometric center in rear pattern plate plate face is called the center line of this mould;
