More specifically, after moulding finished, slide block 120 maybe be because the cohesive force of frictional force or shaped article colloid though the product slide block moves after causing moulding, thereby cause distortion or product fracture when release (promptly breaking away from shaped article).The setting of the distortion disease-prevention institutions 160 in the utility model can prevent that this type of situation from producing.Because slide block 120 is when mobile, pin 163 can produce friction against shaped article 10 owing to the jacking force of patrix, thereby when slide block 120 moved, pin 163 kept motionless, to prevent shaped article 10 motions.After slide block 120 broke away from shaped article, pin 163 was release.Therefore, the delay of pin 163 is release, has prevented to drive when slide block 120 is release shaped article 10 motions, thereby has caused phenomenons such as distortion or product fracture to produce.
Preferably, slide block 120 comprises a plurality of slide units that are spliced.As shown in Figure 4, be the automobile of the utility model schematic perspective view with auxiliary fasia console mould counterdie inner slide.In the illustrated embodiment, slide block 120 comprises a plurality of slide units such as 121,122,123,124,125,126.Because slide block 120 is bigger, need material many, and processed complex.Therefore, for solving this difficult problem, the utility model has adopted spliced slide block structure, promptly forms slide block through splicing a plurality of slide units.Thus, can save material, and be convenient to processing, greatly reduce the development cost of mould.
In addition, counterdie 100 also comprises the needle valve hot flow path.Glue-feeding system adopts the big mouth of a river of this needle valve hot flow path directly to advance glue.Plastic melt directly gets into shunting nozzle by the big end of sprue and gets into mold cavity by shunting nozzle again, characteristics such as have therefore that flow resistance is little, the flow process that flows is short and pipeline time is long.And, adopt the needle valve hot flow path, can control melt and what reach every the glue time of advancing, therefore can solve the fusion line defective.For auxiliary fasia console, its intensity is very important, can not have a bit fusion defective, otherwise insufficient strength can directly have influence on the security performance of automobile.And adopt the needle valve hot flow path, the injection pressure loss is minimum again, directly advances glue on product, so just solves product injection defect problem effectively, and is discontented like filling, current mark etc.
