Abstract
The invention discloses a mold formed by utilizing a relative oblique slip mechanism of a slide block and a slide block insert and belongs to the field of thermoplastic forming molds. The mold is characterized by internally structurally comprising a movable mold insert, movable mold inserts A and B, slide block inserts A, B and C, a slide block seat, shouldered tap bolts A and B and springs A and B. The inner connection mode is that the slide block insert B and the slide block seat are in surface contact and tight fit and are limited, and are connected and limited by a hanging table and locked and fixed by the bolts; and the slide block insert B and the slide block insert A are in surface contact and sliding fit. The back-off demolding motion process is that an inverted buckle at the front end of a plastic product lead-in opening is separated by virtue of slide of the slide block insert B under the action of the tension of the springs A and B, and an inverted buckle at the rear end of a plastic product is separated by virtue of oblique slip of the slide block insert A. The mold disclosed by the invention has the beneficial effects that according to the relative oblique slip mechanism of the slide block and the slide block insert, the two inverted buckles with different requirements at the same part of the plastic product are separated, the mold structure is simplified, the mold space is saved, and the production efficiency is improved.
