Gear Worm Mold

Abstract

The invention provides a mold of a worm with gears. The mold of a worm with gears comprises an upper mold with a thread injection molding cavity and a lower mold with a gear injection molding cavity; the upper mold is internally provided with a first insert; the thread injection molding cavity is arranged in the first insert; the first insert is rotatably arranged in the upper mold; the thread injection molding cavity is arranged in a rotatable first insert; when in demoulding, the first insert in the rotatable mold can be rotated to enable a screw part of a worm with gears to be demoulded smoothly, so that a thread injection molding product can be demoulded directly for the mold depending on the structure of the mold, and the demoulding difficulty is lowered; a push plate is arranged between the upper mold and the lower mold; the push plate is provided with a connecting part containing cavity for connecting the thread injection molding cavity and the gear injection molding cavity; the end part of the worm with gears is of a gear structure, therefore, a push plate structure is arranged in demoulding, and demoulding push force is applied to gear parts of the push plate structure in demoulding, so that products can be demoulded easily.

Description

technical field [0001] The invention relates to the technical field of auto parts preparation, and more specifically relates to a geared worm mold. Background technique [0002] The internal structure of the car contains a variety of transmission components, such as the position of the air outlet of the car, or the position of the audio bracket. Regardless of the automatic adjustment structure or the manual adjustment structure, the adjustment of the air outlet direction is realized through the screw transmission component. Or realize the adjustment of the pop-up and retraction work of the audio bracket. [0003] The screw transmission parts in the above position on the automobile are generally small screw transmission parts. For example, a transmission worm includes a worm part and a transmission gear arranged on the head of the worm. Since the worm part of the transmission worm has a thread structure, it needs to be used after injection molding is completed. The demouldin...

AI Technical Summary

Problems solved by technology

The usual practice is to set up a power mechanism such as an oil motor to turn the transmission worm out of the mold, which makes the removal of the transmission worm relatively complicated after preparation.

[0004] At the same time, additional working parts are added, which increases the structure of the machine and increases the cost of product preparation
