Abstract
The utility model provides a kind of lampshade injection mold, including die, the die is provided with for shaped article die cavity, sprue, runner and enters glue runner, the sprue is connected with runner, the runner is serpentine, it is described enter glue runner be trapezoidal inclined plane shape, the upper bottom of the trapezoidal inclined plane is connected for low order end and with runner, and the bottom of the trapezoidal inclined plane is connected for high order end and with product die cavity side.The utility model colloid after runner and trapezoidal inclined plane shape respectively through serpentine enter glue runner, into die cavity, so makes the plastic cement filling time short from after sprue outflow, and the pressure for entering glue runner is uniform, and mold temperature cooling is uniform.The generation of the problems such as avoiding gas line, improves formed product presentation quality and strength grade, and molding cycle shortens, production cost reduction.
Description
Technical field
The utility model is related to a kind of injection mold, more particularly to a kind of lampshade injection mold.
Background technology
Injection mold is a kind of instrument for producing plasthetics；Also plasthetics complete structure and accurate dimension are to confer to
Instrument.Injection moulding is to produce a kind of processing method used during some complex-shaped parts in batches.Refer specifically to the thawing that will be heated
Material die cavity is injected by high pressure, through cooling and solidifying after, obtain formed products.Plastic product is also more and more extensive in daily life
Be applied, such as building, machinery, electronics, instrument, instrument each industrial circle.For such mould in original die industry
Lamps structure design molding cycle is long, high cost, production poor product quality etc., such as, and design arm's length standard design Jiao Kou originally
When, the injection cycle of product is long, and poor product quality, defective products is high.In injection moulding, because lampshade product is larger, product material
PC plastic cement is generally used, poor fluidity, when glue is entered using arm's length standard design Jiao Kou, can cause the position of the glue-feeder of product
The quality problems such as gas line occur.
Utility model content
The technical problems to be solved in the utility model is directed to above-mentioned the deficiencies in the prior art, there is provided a kind of lampshade injection mould
Tool, allows melt plastic cement to rapidly enter die cavity, it is to avoid generation the problems such as gas line, trapped gas, improves formed product outward appearance matter
Amount and strength grade, molding cycle shorten, production cost reduction.
To achieve these goals, the technical scheme that the utility model is used is as follows：
A kind of lampshade injection mold, including die, the die are provided with for shaped article die cavity, sprue, shunting
Road and enter glue runner, the sprue is connected with runner, the runner is serpentine, it is described enter glue runner be trapezoidal oblique
Planar, the upper bottom of the trapezoidal inclined plane is connected for low order end and with runner, the bottom of the trapezoidal inclined plane for high order end and
Side with product die cavity is connected, and the die is provided with exhaust passage, and the exhaust passage is set around product die cavity semicircle
And away from the side of glue runner is entered, the exhaust passage is connected with product die cavity, and the exhaust passage is set from shallow to deep, institute
It is shallow end that exhaust passage is stated near one end of product die cavity.
Further, it is provided with cooling water channel in the die.
The beneficial effects of the utility model are：Enter that normal runner design is in "S" shape, due to the glue ejected from sprue
Body pressure is maximum, and speed is also most fast, but by after the buffering of serpentine, the pressure for so entering glue runner does not just have
It is so big；And enter glue runner for trapezoidal inclined plane shape, upper bottom is low order end and is connected with runner, go to the bottom for high order end and with
Product die cavity is connected, and colloid is entered from after runner outflow by the low order end for entering glue runner, then is flowed out from high order end, such energy
Colloid is again passed by into glue runner buffering, is entered in product type chamber after reducing pressure, and enter the low order end glue-feeder of glue runner
It is smaller, enter the high order end gum outlet of glue runner than larger, and exhaust passage is set around product die cavity, is designed to half
Round shape, and the side that principle enters glue runner is arranged on, so make the plastic cement filling time short, the pressure for entering glue runner is uniform, type
Gas in chamber can be discharged quickly and evenly, and mold temperature cooling is uniform.The generation of the problems such as avoiding gas line, trapped gas, improves and produces
Product molded appearance quality and strength grade, molding cycle shorten, production cost reduction.
Brief description of the drawings
Fig. 1 is mould core structure schematic diagram of the present utility model；
Fig. 2 is structural representation of the present utility model；
Fig. 3 is another viewing angle constructions schematic diagram of the present utility model.
Specific embodiment
The utility model is further described below in conjunction with accompanying drawing：
A kind of lampshade injection mold as shown in Fig. 1 to Fig. 3, including die 1, the die 1 are provided with for being molded product
Product die cavity 2, sprue 3, runner 4 and enter glue runner 5, the sprue 3 is connected with runner 4, and the runner 4 is
Serpentine, it is described enter glue runner 5 be trapezoidal inclined plane shape, the upper bottom of the trapezoidal inclined plane is connected for low order end and with runner 4,
The bottom of the trapezoidal inclined plane is high order end and is connected with the side of product die cavity 2.So that colloid is when die cavity is entered, passed through after elder generation
Cross runner 4 and enter the buffering of glue runner 5, the colloid pressure of so entrance product die cavity is uniform, it is to avoid the problems such as gas line
Produce, improve the presentation quality of formed product 2 and strength grade, molding cycle shortens, production cost reduction sets on the die 1
There is exhaust passage 6, the exhaust passage 6 is set and away from the side for entering glue runner, the exhaust passage around the semicircle of product die cavity 2
6 are connected with product die cavity 2, and the exhaust passage 6 is set from shallow to deep, and the exhaust passage 6 is near one end of product die cavity 2
It is shallow end.
Cooling water channel 7 is provided with the die 1.
The operation principle of the present embodiment：During work, because colloid is ejected from sprue 3, subsequently into the shunting of serpentine
After road 4 is buffered, the pressure for so entering glue runner 5 is just less big；And enter glue runner 5 for trapezoidal inclined plane shape, upper bottom is
Low order end and it is connected with runner 4, goes to the bottom as high order end and be connected with the side of product die cavity 2, colloid flows out from runner 4
The low order end by entering glue runner 5 enters afterwards, then enters the side of die cavity from high order end, and so energy colloid is again passed by into glue runner
5 bufferings, enter in product type chamber 2 after reducing pressure, and it is smaller to enter the low order end glue-feeder of glue runner 5, enters glue runner 5
High order end gum outlet is than larger, and exhaust passage 6 is set around product die cavity 2, is designed to semicircle shape, and be arranged on
Principle enters the side in the road of glue stream 5, so makes the plastic cement filling time short, and the pressure for entering glue runner is uniform, and the gas in die cavity can be quick
Equably discharge, mold temperature cooling is uniform.The generation of the problems such as avoiding gas line, trapped gas, improves formed product presentation quality
And strength grade, molding cycle shortening, production cost reduction.
The above is not imposed any restrictions to this new technical scope, it is all according to the utility model technical spirit to
On embodiment any modification, equivalent variations and the modification made, still fall within the range of this new technical scheme.
