Abstract

The invention discloses an automobile door panel injection mold. The automobile door panel injection mold comprises a fixed mold base and a movable mold base. A fixed mold core and a movable mold coreare welded to the upper end of the fixed mold base and the lower end of the movable mold base correspondingly. The top end of the fixed mold core corresponds to the bottom end of movable mold core. Two micro hydraulic cylinders are arranged in the fixed mold core. Ejector pins are connected with output shafts of the two micro hydraulic cylinders. The ejector pins are sleeved with an ejector pin plate. An electromagnetic relay is arranged on the fixed mold base. By arranging the micro hydraulic cylinders controlled by the electromagnetic relay in the fixed mold core, the micro hydraulic cylinders are used for driving the ejector pins of a two-section structure to move up and down in a fixed model base and a cavity, thus, the ejector plate with a large area is used for providing lifting support action force for a door panel model, the door panel model can be quickly separated from the cavity, and the pressure borne by the ejector pins is reduced; and a guide rod fixedly connected with the fixed mold base achieves the support effect for up and down movement of the movable mold core, and the demolding efficiency and accuracy are advantageously improved.

Description

technical field [0001] The invention relates to the technical field of injection molding of automobile door panels, in particular to an injection mold for automobile door panels. Background technique [0002] Automobile door panels are an indispensable part of automobile manufacturing, which can provide safety protection for drivers and passengers. However, under the existing technology, there are still certain technical difficulties in the injection molding of automobile door panels. Automobile door panels with mesh are currently widely used, but the manufacturing process is extremely troublesome. Due to the small distance between the mesh holes, it is impossible to use directly large thimbles to eject. Under the existing technology, only thimbles with a diameter of 1.5mm or 2mm can be used. However, due to the large ejection distance, these small thimbles themselves need to bear a great deal of pressure. The extrusion force makes these thimbles very prone to bending or ev...
