In the figure: the core-pulling mechanism comprises a transverse slide block pressing plate 11, a transverse slide block 12, a core-pulling driver 13, a vertical slide block 14, a slide block 15, an insert 16, a groove 17, an inclined bump 18, a forming surface 19, a stop block 20 and a second forming surface 21.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, the cavity back-drawing mechanism for the automobile instrument panel body comprises a transverse sliding block pressing plate 11, a transverse sliding block 12 is connected to the end face of the bottom of the transverse sliding block pressing plate 11, a core-drawing driver 13 is arranged at the end of the transverse sliding block 12, an output shaft of the core-drawing driver 13 is connected with the transverse sliding block 12, and a vertical sliding block 14 is movably connected to the transverse sliding block 12. When the movable mold plate is not shown to be separated from the fixed mold plate, the molded plastic part is irregular, so that the molded plastic part is clamped on the mold, and the demolding direction is not in the same direction as the irregular surface of the molded plastic part, therefore, the core pulling driver 13 needs to work to drive the transverse slide block 12 to move towards the direction close to the molded plastic part, when the transverse slide block 12 moves, the vertical slide block 14 moves and drives the molded plastic part to be separated from the irregular molding surface, and the subsequent demolding process is facilitated without touching the irregular molding surface.

The transverse sliding block 12 moves along the horizontal direction of the transverse sliding block pressing plate 11, the bottom end face of the transverse sliding block 12 is an inclined plane, and a groove 17 is formed in the inclined plane of the transverse sliding block 12. When the transverse sliding block 12 moves, the movement of the vertical sliding block 14 can be driven through the inclined angle of the groove 17.

The vertical sliding block 14 extends into the groove 17 to form clamping connection with the groove 17, and the vertical sliding block 14 can slide along the groove 17 in the groove 17. The vertical sliding block 14 is always in the connection state with the groove 17 and cannot be separated, and when the transverse sliding block 12 moves, the transverse sliding block 12 drives the vertical sliding block 14 to move back and forth along the groove 17 because the vertical sliding block 14 is always in the connection state with the groove 17.

The groove 17 is convex, and the width of the groove at the outer side of the convex groove 17 is smaller than that of the groove at the inner side of the convex groove 17. Because the groove width of the outer side of the groove 17 is smaller than the inner side groove width of the convex-shaped groove 17, the parts in the inner side cavities of the rest grooves 17 of the vertical sliding block 14 always slide in the inner side of the groove 17 and cannot slide into the cavity of the outer side of the groove 17, and the vertical sliding block 14 is ensured to be always in a connection state with the groove 17.

The end of the vertical slide block 14 is connected with an insert 16, and when the transverse slide block 12 drives the vertical slide block 14 to move, the vertical slide block 14 repeatedly moves back and forth along the axial direction of the insert 16. The left and right sides of the vertical sliding block 14 are limited, when the transverse sliding block 12 drives the vertical sliding block 14 to move, the vertical sliding block 14 can only move up and down along the groove 17, and when the vertical sliding block 14 moves, the insert 16 moves along with the vertical sliding block 14.

The vertical sliding block 14 is provided with an inclined convex block 18, and the horizontal height of the inclined convex block 18 is smaller than that of the vertical sliding block 14. After the movable mold plate is separated from the fixed mold plate, the plastic part needs to be indirectly separated from the molding surface on the mold through the movement of the vertical slide block 14, if the horizontal height of the oblique projection 18 is too large, the moving distance of the plastic part is limited, and the plastic part cannot be completely separated from the molding surface, so in this example, the horizontal height of the oblique projection 18 is smaller than the horizontal height of the vertical slide block 14.

The inclined convex block 18 is movably connected with a sliding block 15, and one side of the sliding block 15, which is far away from the inclined convex block 18, is provided with a first forming surface 19 for forming the surface of a plastic part. When the vertical slider 14 moves upward, the inclined projection 18 can drive the slider 15 to move along the inclined projection 18 in a direction away from the plastic part.

The inclined convex block 18 is convex, the width of the outer end face of the convex inclined convex block 18 is larger than the width of the end face of the inner side of the convex inclined convex block 18, and the inclined convex block 18 is inserted into the sliding block 15 and movably clamped with the sliding block 15. Since the width of the outer end surface of the oblique projection 18 is larger than the inner end surface of the convex oblique projection 18, the sliding block 15 is always in the connection state with the oblique projection 18, and since the oblique projection 18 is in an oblique shape, when the vertical sliding block 14 moves, the oblique projection 18 plays a role of guiding and dragging.

The forming surface 19 is a concave arc surface, when the mold is closed, the slide block 15 is abutted against the insert 16, a second forming surface 21 for forming the surface of a plastic part is arranged on the end surface of the insert 16 close to the slide block 15, and the second forming surface 21 is connected with the first forming surface 19 and is inclined. The plastic parts formed on the first forming surface 19 and the second forming surface 21 are irregular, and in the demolding process, the sliding block 15 and the insert 16 need to be separated from the plastic parts, so that the plastic parts are prevented from being collided and extruded in the demolding process.

The working principle of the injection mould is as follows: after the movable mold plate is separated from the fixed mold plate, the core-pulling driver 13 drives the transverse slide block 12 to move towards the direction close to the plastic part, the groove 17 drives the vertical slide block 14 to move upwards along the groove 17 and drive the insert 16 to move away from the plastic part, during the movement of the vertical slide block 14, the inclined lug 18 is connected with the slide block 15, so that the slide block 15 can be driven to move away from the plastic part, the plastic part is enabled to move away from the concave arc surface on the first molding surface 19, and then the plastic part is enabled to move out of the mold and complete demolding under the condition that the inclined rod (not shown in the figure) of the injection mold does not touch the first molding surface 19 and the second molding surface 21.

The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein may be made by those skilled in the art without departing from the spirit of the invention or exceeding the scope of the invention as defined in the accompanying claims.
