Description
Technical field
The utility model is related to mold injection field, refers in particular to a kind of in-mold molding pressurizing unit.
Background technology
Groove is usually provided with current air bag cover, makes the bottom of groove very thin, convenient and safe air bag ejection；But
During injection moulding, because the bottom of groove is very thin, poor fluidity is caused, not only influence injection efficiency, and easily make air bag cover
Hollowing is produced, total quality is influenceed.
Utility model content
The utility model purpose is to provide a kind of in-mold molding pressurizing unit to overcome the deficiencies in the prior art, when
When not being molded completely also after product injection, cell body is directly squeezed out on product by profiling cutting knife, so as to improve injection effect
Fruit and product quality.
To reach above-mentioned purpose, the technical solution adopted in the utility model is：A kind of in-mold molding pressurizing unit, comprising
Die and the product die cavity in die；The profiling cutting knife and drive that can be extend into product die cavity are provided with the die
The actuating unit of dynamic profiling cutting knife action；The head of the profiling cutting knife is provided with the extruding being engaged with product inside groove shape
Head.
Preferably, the die is fixed mold core or mavable module core.
Preferably, the afterbody of the profiling cutting knife is provided with tool rest；The tool rest is connected with the output end of actuating unit；Institute
State and be additionally provided with back-moving spring on tool rest in die.
Preferably, the actuating unit is drive cylinder or drives oil cylinder.
Due to the utilization of above-mentioned technical proposal, the utility model has following advantages compared with prior art：
In-mold molding pressurizing unit described in the utility model when not being molded completely also after product injection, by imitative
Shape cutting knife directly squeezes out cell body on product, so that improve injection effect and product quality, and simple structure, it is easy for installation.
