Description
Technical field
The utility model relates to lampshade mould, is specifically related to a kind of highly exhaust LED lamp cover mould.
Background technology
During mold injection, our more common products have free time silk, serious even scraps, and the problems referred to above are vented bad causing by mould self.When melted material filling speed is faster than the exhaust velocity in die cavity, the air in die cavity is compressed to reach a high temperature at once, and the part that formed products contacts with high temperature air produces burns; Because resistance of holding one's breath in die cavity prevents the flowing of melted material, slow down flow velocity, cause filling bad phenomenon; Air in die cavity and gas flow, inhibit the flowing of melted material, and divisional plane is expanded, and causes and expand projected area same effect, die joint being floated, and produces flash.This type of situation all has a strong impact on yield rate, waste resource, increases cost, especially to the lampshade mould of light sensitive, occurs that free time silk is undoubtedly the fatal shortcoming of product.Therefore, we need badly and a kind ofly can adapt to high-speed production and the LED lamp cover mould be better exhausted.
Utility model content
In view of this, the utility model, for the deficiencies in the prior art, is highly vented LED lamp cover mould to the open one of traditional LED lamp cover mould.
The purpose of this utility model is achieved through the following technical solutions:
A kind of highly exhaust LED lamp cover mould, comprise patrix, counterdie, upper mold core and lower mold core, offer framed in the middle part of described patrix, low mold frame is offered in the middle part of described counterdie, described upper mold core be arranged at framed in, upper mold core and upper framed be matched in clearance, described lower mold core is arranged in low mold frame, lower mold core and low mold frame are matched in clearance, in described upper mold core, array distribution has 8 lampshade die cavitys, upper mold core die joint is provided with the exhaust passage around each lampshade die cavity, lampshade die cavity array distribution has several blow vents to be connected with exhaust passage, the exhaust passage of adjacent lampshade die cavity is interconnected, described lower mold core is provided with the lampshade mold insert corresponding with described lampshade die cavity, and around described lampshade mold insert, array distribution has three the exhaust mold inserts embedding lower mold core.
Upper mold core arranges exhaust passage, lower mold core arranges exhaust mold insert, during injection moulding, intracavity gas discharges mould by exhaust passage and exhaust mold insert gap, the situations such as effective solution is burnt because being vented the bad product caused, it is bad to fill, flash, good exhaust structure not only improves the yield rate of product injection moulding but also speeds injection moulding speed, raises the efficiency.
Described exhaust mold insert front is provided with concave surface, and two sides are provided with parallel lugs, and exhaust mold insert lower end tilts to the inside and embeds in lower mold core, and exhaust mold insert lower end is connected with thimble.
Exhaust mold insert two ends are respectively provided with a parallel lugs, any side of described parallel lugs is parallel with exhaust mold insert corresponding side surface, exhaust mold insert lower end inclination 2-5 ° to the inside, and exhaust mold insert lower end is shunk and embedded lower mold core, described exhaust mold insert bottom surface is provided with thimble groove, thimble groove connecting ejector pin.Two ends arrange parallel lugs is more of value to the exhaust location of mold insert and stability, and leaving area when simultaneously increasing injection moulding, lower end is done certain angle and tilted more to be conducive to exhaust mold insert ejecting product and reset.
Described patrix is provided with some locking grooves, is provided with the latch segment for locking upper mold core in locking groove; Described counterdie is provided with some locking grooves, is provided with the latch segment for locking lower mold core in locking groove.
It is more difficult for being loaded or take out framed by core rod when core rod is too large, and with framed adjacent two sides for datum level, remaining two sides arrange latch segment, only first latch segment need be pulled down during handling, just can complete the dismounting of core rod easily, easy to operate, structure is simple.
Described upper mold core is also provided with the first exhaust expanding channels adjacent ring around the exhaust passage of lampshade die cavity, and relative first exhaust interchannel is provided with the second exhaust expanding channels, and the exhaust passage around lampshade die cavity is provided with some exhaust outlets and stretches out upper mold core side.
Adjacent ring around lampshade die cavity exhaust passage by first exhaust expanding channels, relative first exhaust passage by second exhaust expanding channels, like this arrange make die venting evenly, injection moulding is more stable.
The utility model, relative to prior art, has following beneficial effect:
1. the utility model is by arranging exhaust passage and exhaust mold insert, and the situations such as effective solution is burnt because being vented the bad product caused, it is bad to fill, flash, improve the yield rate of product injection moulding, raise the efficiency.
2. the utility model structure is simple, saves material, and manufacture difficulty is low and have higher stability.
