In the description of the present utility model, it should be understood that the azimuth or positional relationship indicated by the azimuth words such as "upper, lower" and "top, bottom", etc. are generally based on the azimuth or positional relationship shown in the drawings, and are merely for convenience of description and simplification of the description, and these azimuth words do not indicate or imply that the apparatus or element to be referred to must have a specific azimuth or be constructed and operated in a specific azimuth, without limiting the scope of protection of the present utility model; the orientation word "inner and outer" refers to inner and outer relative to the contour of the respective component itself.
As shown in fig. 1-5, a demoulding mechanism of a car navigation bottom shell comprises a front mould panel 1, a front mould plate 2, a push plate 3, a rear mould plate 4, mould legs 5 and a bottom plate 6, wherein the front mould panel is arranged on one side of the front mould plate, a front mould sliding block 7 is arranged in the push plate, the push plate is arranged between the front mould plate and the rear mould plate, the rear mould plate is fixedly connected with the bottom plate through mould legs, two mould legs are arranged at intervals, a thimble plate 8 and a thimble fixing plate 9 fixedly arranged at the upper end of the thimble plate are arranged between the mould legs, a thimble is fixedly arranged on the thimble fixing plate, and the lower end of the thimble plate is fixedly provided with a mandril which passes through the bottom plate and is connected with an ejection system of an injection moulding machine; the front mould sliding block is internally provided with a spring needle assembly 11, and the front mould panel is fixedly provided with a transmission assembly 12 for driving the spring needle assembly to move.
Thus, in the die sinking process, the front die panel drives the transmission assembly to move, and the transmission assembly drives the spring needle assembly to move so as to loose core. When the mold is closed, the transmission assembly drives the spring needle assemblies to move, and the mold is closed.
The spring needle assembly comprises a spring needle rod 21, a connector 22 is arranged at the upper end of the spring needle rod, an inclined surface is arranged on the connector, a limiting ring 23 is fixedly arranged on the spring needle rod, a sliding hole which is in sliding fit with the spring needle rod is formed in a front mold sliding block, a containing groove is formed in the front mold sliding block, the containing groove is located outside the sliding hole, the containing groove and the sliding are coaxially arranged, a spring 24 with compression amount is placed in the containing groove, and the spring with compression amount is sleeved on the outer side of the spring needle rod and located below the limiting ring.
