Abstract

The invention discloses a device for two-stage ejection and forcible stripping of a snap joint. The device comprises a mold core A plate, a mold core B plate, a baseplate, an elastic pin and a plastic part push rod, wherein the upper part of the mold core B plate is connected to the mold core A plate, and the lower part of the mold core B plate is arranged on the baseplate; the plastic part push rod passes through the baseplate and is connected to an ejector plate; the ejector plate is arranged on the baseplate and in the mold core B plate; a return pin spring is arranged between the ejector plate and the mold core A plate; and one end of the elastic pin passes through the mold core A plate and is connected to the snap joint, and the other end of the elastic pin passes through the ejector plate and is connected to the baseplate. The device has the beneficial effects that the snap joint with elastic deformation is forcibly stripped by using the elastic pin, and the device is simple in structure, reliable in performances, convenient to use and easy to maintain in later period and meanwhile has a very good using effect on molding of a snap joint structure in a plastic injection mold.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a device for secondary ejection and strong release of buckles. Background technique [0002] In daily life and industrial production, many plastic parts have many elastic buckle structures according to the requirements of their actual performance. For this kind of buckle structure, the traditional method is adopted most of the time, and the buckle is pulled out with a core-pulling mechanism. When using the traditional core-pulling mechanism, it is necessary to consider the cooperation between the various mechanisms, the sequence of movement, the fixed-distance guidance and the injection pressure to prevent backlash. It obviously increases the complexity of the mechanism, consumes too much cost, and also brings inconvenience to the later maintenance. Contents of the invention [0003] Aiming at the deficiencies in the prior art, the purpose of the present invention is to provide...
