Compared with prior art, the beneficial effects of the utility model are：The injection mold of the anti-shrinkage cavity shrinkage porosity, by arranging
Fixed form so that backing plate is fixedly mounted on the upper surface of fixed form under the fixation of the rivet at its left and right two ends so that fixed
Mould stably can be installed, and arrange groove and sprue gate, can be by sprue gate casting material, while coordinating dynamic above cover half
Mould, forms running gate system, and in the compression spring that is internally provided with of cover half, the wherein elastic force of compression spring is certain value, can be controlled
The pressure of inside grooves processed, effectively prevents the product of inside grooves from excessively shrinking, and prevents the shrinkage porosite of object, arranges expansion link, makes
Cover half is moved up and down under the drive of expansion link below moving die plate, by the movement of dynamic model realize the unlatching of groove with
Closure so that injecting products are convenient, the injection mold of the anti-shrinkage cavity shrinkage porosity, can active balance pressure, prevent object by
In uneven caused shrinkage cavity shrinkage porosity phenomenon of being heated, practicality is stronger.
