And T-shaped sliding grooves are formed in the outer side surfaces of the two sliding blocks, T-shaped guide sliding blocks matched with the T-shaped sliding grooves are fixed on the cavity wall of the fixed template injection molding cavity, inclined counter bores are formed in the bottoms of the two sliding blocks, and guide columns and springs are arranged in the counter bores.

And forming parts are symmetrically arranged on the inner side surfaces of the two sliding blocks.

The utility model has the beneficial effects that:

through improving injection mold dog structural design, can improve in the production of moulding plastics, the easy not hard up problem of dog can realize that the accuracy of mould slider is spacing, avoids appearing the casing that consequently causes and damages the problem, has guaranteed that the product is pleasing to the eye and has promoted the product percent of pass.
