Abstract
The utility model relates to a ventilation equipment field especially relates to a blade injection mold. A blade injection mold, the mould is inside to be equipped with the mould chamber of the blade that is used for moulding plastics, be equipped with on the mould with communicating injecting glue mouth in mould chamber and air inlet, mould intracavity portion is including the first end that is used for forming the blade upper end to and form the second end of blade lower extreme, and be used for forming the third tip of blade air inlet end, and be used for forming the fourth tip of blade air -out end, the degree of depth of fourth tip is less than the degree of depth of first end, the second end and third tip, and the air inlet all is equipped with a plurality of flash wells on being in the fourth tip in mould chamber on the edge of first end, the second end and third tip, and the flash well communicates with each other through the valve runner with mould chamber edge. Be equipped with in this blade injection mold with the communicating flash well in mould chamber to can promote gas in the inside penetrability of blade, increase the air flue rate of undercuting, stabilize injection moulding product's quality.
Description
Technical field
The utility model relates to field of ventilation equipment, particularly relates to a kind of blade injection mold.
Background technology
Fan blade is product comparatively common in field of ventilation equipment, and the shape of blade structure Leaf, size and angle all directly affects the performance of fan blade.In existing technique, adopt the method for gas aided injection mould product can form blade cavity in blade interior, thus the load consumption of leaf weight, minimizing ventilation equipment can be reduced.But, when current blade mold, when adopting the method for gas aided injection mould product, fan blade quality and quality instability, be mainly reflected in when to pass into gas in mould, the air flue that gas is formed in blade interior is lack of standardization, and causes mould inside injection moulding filling uneven because air flue extrudes, and occurs local flash phenomena.
Summary of the invention
In order to solve the problem, the purpose of this utility model is to provide a kind of blade injection mold, is provided with the overflowing well communicated with mold cavity in this blade injection mold, thus can promote that gas is in blade interior penetrability, increase air flue and empty rate, stablize the quality of injecting products.
In order to realize above-mentioned object, the utility model have employed following technical scheme:
A kind of blade injection mold, described mould inside is provided with the mold cavity for injection moulding blade, and mould is provided with the gum-injecting port and air inlet that communicate with mold cavity; Described mold cavity inside comprises the first end for the formation of blade upper end, and forms the second end of blade lower end, and for the formation of the 3rd end of blade air intake, and for the formation of the 4th end of blade outlet air end; The degree of depth of described 4th end is less than the degree of depth of first end, the second end and the 3rd end, air inlet is on the 4th end of mold cavity, the edge of first end, the second end and the 3rd end is equipped with some overflowing well, and overflowing well is communicated by valve gate with mold cavity edge.
The desired blade manufactured of the utility model need adopt above-mentioned injection mold, and coordinates the method for gas aided injection mould product to be made; The mold cavity edge of injection mold is provided with some overflowing well, when injection moulding, passes into gas can form air flue at interiors of products by air inlet, and under the extruding of air flue, the last filling of mould material occurs in overflowing well, and integral molded plastic product is regular.In addition, because air inlet is in the 4th end of mold cavity, when toward air inlet injecting gas, gas forms in injecting products inside the air flue leading to first end, the second end and the 3rd end, therefore all may there is local flash phenomena in three side sidewalls of injecting products, overflowing well need be set in the first end of mold cavity, the second end and the 3rd end edge, overflowing well be taken the shape of the letter U and surrounds the state of air inlet.Comprehensive said structure, the program, by promoting that gas is in blade interior penetrability, increases air flue and empties rate, reach the object of stable injecting products quality; After formed product depanning, can the flash that formed at overflowing well and valve gate of place to go, retained product body.
Accompanying drawing explanation
Fig. 1 is the structure sectional view of blade injection mold.
Fig. 2 is the structural representation of blade injection mold.
Detailed description of the invention
Below in conjunction with accompanying drawing, preferred embodiment of the present utility model is described in further detail.
A kind of blade injection mold as shown in Fig. 1 ~ Fig. 2, described mould 1 inside is provided with the mold cavity 11 for injection moulding blade, and mould is provided with the gum-injecting port and air inlet 12 that communicate with mold cavity 11; Described mold cavity 11 inside comprises the first end 21 for the formation of blade upper end, and forms the second end 22 of blade lower end, and for the formation of the 3rd end 23 of blade air intake, and for the formation of the 4th end 24 of blade outlet air end; The degree of depth of described 4th end 24 is less than the degree of depth of first end 21, the second end 22 and the 3rd end 23, air inlet 12 is on the 4th end 24 of mold cavity 11, the edge of first end 21, the second end 22 and the 3rd end 23 is equipped with some overflowing well 13, and overflowing well 13 is communicated by valve gate 14 with mold cavity 11 edge.
The desired blade manufactured of the utility model need adopt above-mentioned injection mold, and coordinates the method for gas aided injection mould product to be made; Mold cavity 11 edge of injection mold is provided with some overflowing well 13, when injection moulding, passes into gas can form air flue at interiors of products by air inlet 12, and under the extruding of air flue, the last filling of mould material occurs in overflowing well 13, and integral molded plastic product is regular.In addition, because air inlet 12 is in the 4th end 24 of mold cavity 11, when toward air inlet 12 injecting gas, gas forms in injecting products inside the air flue 15 leading to first end 21, the second end 22 and the 3rd end 23, therefore all may there is local flash phenomena in three side sidewalls of injecting products, overflowing well 13 need be set at the first end 21 of mold cavity 11, the second end 22 and the 3rd edge, end 23, overflowing well 13 be taken the shape of the letter U and surrounds the state of air inlet 12.Comprehensive said structure, the program, by promoting that gas is in blade interior penetrability, increases air flue and empties rate, reach the object of stable injecting products quality; After formed product depanning, can the flash that formed at overflowing well 13 and valve gate 14 of place to go, retained product body.
