Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1, fig. 2, and fig. 3, the injection molding mold for the automobile mask comprises an upper mold 1, a lower mold 2, and a jacking mechanism for ejecting the automobile mask, wherein the jacking mechanism is composed of an upper jacking sleeve 3, a jacking rod 4, and a cylinder 5, an inner groove for the jacking rod 4 to push into is formed in the bottom of the upper jacking sleeve 3, the cylinder 5 is connected to the bottom of the jacking rod 4 through a cylinder pushing plate 6, the jacking rod 4 is driven by the cylinder 5 to push into the inner groove and drive the upper jacking sleeve 3 to lift upwards for ejecting the automobile mask, a spring 7 is sleeved on the jacking rod 4 and between the cylinder pushing plate 6 and the upper jacking sleeve 3, a groove 8 for the upper jacking sleeve 3 to access is formed in the lower mold 2, a plurality of diameter limiting bulges 9 are outwardly protruded in the circumferential wall of the upper jacking sleeve 3, a diameter limiting ring 10 which is outwardly protruded is formed on the groove wall of the groove 8, a plurality of positioning grooves 11 for radially positioning the corresponding diameter limiting bulges 9 are formed on the diameter limiting ring 10, the upper jacking sleeve 3 is radially limited by the formed diameter limiting ring 10, and the stability of the jacking sleeve 3 is improved.

In order to prevent the seizure property of the axial movement of the upper knock sleeve 3, the diameter limit projection 9 is in clearance fit with the positioning groove 11.

In a further detail, the upper top sleeve 3 is wrapped by a heat insulation layer, and the heat insulation layer has certain flexibility, so that the heat insulation layer is prevented from being in hard-to-hard contact with the forming module, and damage is reduced.
