Abstract
The present invention discloses a high-temperature resistant automotive component forming mold, which relates to the field of mold technology. Due to the continuous injection molding work of the mold, the material will fill the gaps in the mold cavity. If the formed material is directly extracted, demolding is difficult, and the material in the gap is torn and separated, resulting in a large amount of material in the gap and affecting the use of the mold. Through the elastic deformation of the spring plate, when the formed plate is clamped and slid inward, the spring plate is pulled to produce deformation, and a tensile force is generated by the deformation to pull the formed plate outward. After the material is cooled and formed, the formed plate loses the limiting force of inward clamping. At this time, the spring plate pulls the formed plates apart through the slider, making the mold better demolding and avoiding the direct extraction of the formed material. The material in the gap is torn and separated, There is a large amount of material in the gap, which affects the use of the mold.

In the slide assembly 35, the forming plate 34 is subjected to an inward clamping force, and when sliding, the elastic plate 351 is deformed by the tension of the sliding block 353, so that the sliding block 353 slides in the fixed groove block 352, after the injection molding cooling is completed, the bottom block 1 is separated from the top block 2, at this time, the press seal block 38 gradually releases the forming plate 34, and the deformation is recovered by the elastic plate 351, and the forming plate 34 is pulled to be separated by the sliding block 353.
In the process of injecting the material, the cavity is injected from the bottom through the injection pipe 8, so that air in the cavity is extruded upwards in the process of continuously injecting the material, and is discharged from a gap between the exhaust hole of the exhaust hood 361 and the hole sealing block 364 at the moment, and then is guided out through the air outlet hole, when the material is gradually filled in the cavity, the viscosity of the material pushes the bottom ring 363 to move upwards, the hole sealing block 364 gradually seals the exhaust hole, and when the material is thoroughly sealed, the bottom ring 363 enters the annular groove of the exhaust hood 361.
In the demolding process, the top block 2 is separated from the bottom block 1, at this time, the slide column 375 is driven by the exhaust hood 361 to separate, so that the slide column 375 is drawn out from the groove drum 372, and in the drawing process, the protrusions of the slide column 375 are continuously contacted with the protrusions of the slide plate 373 and separated, so that the slide plate 373 slides outwards in the process, and the molded part is pushed from inside to outside, so that the material is deformed and separated from adhesion with the mold.
