Detailed description of the invention
For the ease of the understanding of those skilled in the art, be further described the utility model below in conjunction with embodiment and accompanying drawing, the content that embodiment is mentioned is not to restriction of the present utility model.
As shown in Figures 1 to 4, the cavity structure of a kind of double-color mold of the utility model, comprise die cavity template 1, this die cavity template 1 is provided with the die for shaped article, described die is provided with connecting portion 2, first die portion 3 and the second die portion 4, described second die portion 4 is connected with described connecting portion 2, described first die portion 3 is connected with this second die portion 4, the outside in described first die portion 3 offers the some fixing holes 8 for fixing first time shaped article, and described first die portion 3 and the second junction, die portion 4 are provided with transition lug boss 5.
Concrete, the conveniently demoulding of final products, the projection of described lug boss 5 for seamlessly transitting, as shown in Figure 3.In actual application, the first injection molding product section of injector is the first die portion 3, by offering fixing hole 8 in the outside in the first die portion 3, in the process of shaping first die portion 3 product, first sizing material will be filled in fixing hole 8, after this portioned product is shaping, the fixing hole 8 that the inwall of product molds outside some salient points 10 and the first die portion 3 snaps together, thus this portioned product is fixed in the first die portion 3 tightly, prevent this portioned product from running glue and contraction, effectively reduce the deflection of product, thus when making the product of injector injection moulding second die portion 4 part again, the sizing material of injection well can be connected with the sizing material injected before, before effectively avoiding, the phenomenon staggered and cause product bad in rear double injection sizing material position, be specially adapted to the linking between flexible glue material and ebonite material, and the linking between the large sizing material of shrinkage factor, transition lug boss 5 is provided with in the first die portion 3 and the second junction, die portion 4, when shaping to the first die portion 3 partial syringe, the bottom of this portioned product is coated on this transition lug boss 5, when making product for shrinking, be subject to the resistance of transition lug boss 5, strong fixation is played to product, prevents this portioned product to run glue and contraction further.
The utility model injects the deflection of rear product by control first die portion 3 and lug boss 5, the shaping product of second die portion 4 partial syringe well can be connected with it, ensure that the form accuracy of product, reduce product because be connected bad fraction defective, improve production efficiency and reduce cost.
