According to the further technical scheme, a wear-resistant block is arranged below the shovel machine, and the limiting block is in contact with the wear-resistant block for limiting during core pulling.

According to the further technical scheme, in the mold closing state, the four pitched roof inserts and the slide block are kept on the same horizontal plane, the slide block is drawn out of the groove in the mold opening state, the pitched roof inserts are retracted towards the center of the guide block by 1.6mm, and the small step surfaces on the side surfaces are reversely buckled by 0.74 mm.

The beneficial effects of the utility model

The shovel machine is fixed on the front die, and the stroke of the T-shaped groove core-pulling slide block is 40.25mm when the die is opened; the core of the sliding block is pulled, the limiting block limits the position, the front end of the sliding block is separated from the two grooves, after the grooves are lack of extrusions, springs are arranged on the pitched roof insert to apply elasticity to the pitched roof insert, the four pitched roof inserts do retraction movement towards the center of the guide block, after the pitched roof insert retracts, the pitched roof is ejected out without interfering with a product, the pitched roof assembly is driven by the pitched roof rod to pull the core outwards together, then the mold is ejected out, and then the product is taken out;

during die assembly, the sliding block is driven by the shovel to be inserted into the groove, the four pitched roof inserts are restored to the initial positions, and the forming of the product hole and the accuracy of the size are guaranteed.
