Specific embodiment
The utility model is described in further detail with reference to embodiment and accompanying drawing, but implementation of the present utility model
Mode not limited to this.
As shown in Figures 1 to 7, the utility model realizes the note of flexible glue bag flexible glue by a kind of flexible glue bicolor injection mould
Molding product, mainly improves in terms of three to injection mold：Product design, mold design and processing and the test of sizing material
Selection.
The product that Fig. 1 is produced by a kind of flexible glue bicolor injection mould of the utility model, the product include simple products and
Complex product, the wall thickness of complex product is more difficult to more greatly filling, therefore the product penetrates injection simple products in injection using one
Form one and penetrate product 1, two penetrate injection complex product formation two penetrates product 2, according to this product structure, common mould development theory
It is use inverted mold structure design more, if product is in the He of front mould 3 when the product just appears in die sinking using inverted mold design
Ejection is required in rear mold 4, causes the ejection position of glue-feeding system completely inadequate, and the risk of product adhesion front mould 3 is suitable
Greatly, so, formal dress mould is gone out according to the product design, realize disposable ejecting product.
As shown in Figures 2 and 3, in injection moulding process, because product produces cooling meat phenomenon in die cavity 5, product is made
The projection of core 5 and die cavity 6 is hugged, makes product formation sticking to mould, take out difficult, taking out can cause the surface of product to be wiped by force
Wound causes to weigh wounded with mould, in order to prevent causing these defects in processing, is penetrated by one and increases a depanning of front mould 3 for penetrating product 1
The angle at angle 7 improves, but ensures there is sticking to mould power between product and rear mold 4 again, therefore is penetrated one and back-off is designed on product
8, design back-off 8 ensures that product stays in rear mold 4, and the gradient size of designed back-off 8 is 0.1mm, and is increased when two penetrate
Product 2 is penetrated rear in the glue position 10 of drawing that glue post position 9 and increase by two on mold cores 5 are penetrated on the bottom two ends of product 2 so as to increase by two
Sticking to mould power on mould, it is ensured that two penetrate product 2 stays in rear mold, while also making product that ejection is realized in rear mold 4, product is penetrated one
Increase round glue position 11 on 1 base to reach adhesive force of the product in rear mold 4.
As shown in Figures 4 to 7, it is designed and improvement, including front mould 3 and rear mold according to the said goods requirement and to mould
4, the front mould includes A plates 12 and preceding core rod 13, and the rear mold 4 includes B plates 14 and rear core rod 15, and 13 are provided with the preceding core rod
Two inject colloid system 16, and the rear core rod 15 is provided with one and injects colloid system 17, described one inject colloid system 17 enter glue point 18
Position penetrates the appearance profile face 201 of product 2 less than described two, and the preceding core rod 13 is provided with die cavity 6, is set on the rear core rod 15
There is core 5, the core 5 is provided with multiple mold inserts 19, and the mold insert 19 forms pillow position (not indicated in diagram) with preceding core rod 13,
Smooth surface high is processed into the pillow position by grinding machine, and the preceding core rod 13 and the contact of rear core rod 15 form die joint 20, the parting
Smooth surface high is processed into face 20 by Digit Control Machine Tool, and the die joint 20 is separated with the pillow position.To penetrate product 2 relatively multiple due to two
It is miscellaneous, so second injects colloid system 16 and selects full valve needle of hot runner to enter glue, it is contemplated that product will realize automated production, and first penetrates
Glue-feeding system 17 selects to enter glue for banana, prevents from drawing high influence assembling, and the described one glue point position of entering for injecting colloid system 17 is less than
Described two penetrate the appearance profile face of product 2, and a glue runner that enters for injecting colloid system 17 turns ox horn and enters glue runner using hot flow path.
Due in the injection moulding process of the product, two to penetrate product 2 be the difficult filling of comparing, and one penetrate product 1 required precision it is high, use
Digit Control Machine Tool processing die joint 20 is smooth surface high, it is ensured that the double-colored encapsulated clear adhesive of boundary is good and does not produce punching molten, while
Also meet two and penetrate the exhaust of product 2 without going out batch cutting edge of a knife or a sword, be this injection mold be provided with can be processed with grinding machine it is all of
Position is rested the head on, and rests the head on position and separated with the die joint 20, and the design of pillow position improves product excessive glue problem, improves the matter of product
Amount, specifically, be provided with glue post position 9 on the core 5, with two penetrate on product 2 draw that glue position is 10 consistent, product 2 is penetrated in increase by two
Sticking to mould power in rear mold 4.
In injection moulding process, the quality with comparison product of sizing material can also produce influence, due to the different meetings of sizing material hardness
Deformation of products and adhesion front mould are produced, is learnt by practice, improve the two sizing material hardness for penetrating product 2, Product Assembly can be allowed more
Easily, while sticking to mould probability also has certain decline, also there is improvement result to product sticking to mould so as to show that hardness is higher, hardness is got over
It is high smaller to the sticking to mould risk of mould, according to the functional requirement of product, such as light conductivity and shock resistance, while requiring injection mold
Two kinds of TPE flexible glue sizing material difference of hardness have to be larger than 20A, and sizing material final choice LC453-109 (90A) is an injection material, LC453-
108 (70A) are two injection material, so as to reach the requirement of product, make to penetrate product and two combinations for penetrating product are more stablized.
Above-described embodiment is the utility model preferably implementation method, but implementation method of the present utility model is not by above-mentioned
The limitation of embodiment, it is other it is any without departing from the change made under Spirit Essence of the present utility model and principle, modify, replace
Generation, combination, simplification, should be equivalent substitute mode, be included within protection domain of the present utility model.
