Large-angle demoulding mechanism for inclined-plane deep ribs and large-angle support parts of automobile decorative panels

Abstract

The invention discloses a large-angle demolding mechanism for a deep rib on the inclined plane of a supporting part of a decorative plate of an automobile. The demolding mechanism comprises inclined ejector rods (1), an inclined ejector block (2), first inclined connecting rods (3) and a first guide block (4), wherein the first guide block (4) is connected to an ejector plate; sliding blocks (5) are connected in the first guide block (4) in a sliding manner; the upper ends of the inclined ejector rods (1) are fixedly connected to the inclined ejector block (2); the lower ends of the inclined ejector rods (1) are connected to the sliding blocks (5) in a rotating mode; the first guide block (4) is fixedly connected to the ejector plate; the middle parts of the first inclined connecting rods(3) are connected to the sliding blocks (5) through first sliding sleeves (6); and the first sliding sleeves (6) are connected to the sliding blocks (5) in a rotating mode. Compared with the prior art, the demolding mechanism has the advantage that the machining precision is relatively low, the stability in use is relatively good, the maintenance period is relatively long, the production continuity of a mold can be improved, and the production efficiency of the mold can be improved.

Description

technical field [0001] The invention relates to a demoulding mechanism of a mould, in particular to a demoulding mechanism with inclined plane, deep ribs and large angle of an automobile decorative plate support. Background technique [0002] Deep ribs (generally refers to the height of the ribs is more than 1cm higher than the surface), and the deep ribs have an angle on the inclined surface of the car decorative panel support (see Figure 10), and if the angle is above 12°, a large angle of oblique drawing is required core mechanism to release the mold. [0003] The large-angle demoulding of the prior art, such as the publication number, is CN 204054517 U, and the name is a practical large-angle oblique ejection core-pulling structure disclosed "a practical large-angle oblique ejection core-pulling structure, including a fixed template and a movable template, a mold cavity for injection molded products is provided between the fixed template and the movable template, and a ...

Problems solved by technology

", although the slider is connected with the ejector rod through the rotating shaft, so that the inclined ejector block can slide out at a large angle to realize core pulling, but in the actual use process, because the slider is connected with the ejector rod in rotation, and the inclined connecting rod is to guide The guide block also slides, which leads to higher machining accuracy requirements when the sliding distance is greater than 2cm, otherwise the guide block is easy to get stuck and cannot be completely demolded, and it is also easy to There are bite marks, the inclined connecting rod is easy to be damaged, and the inclined connecting rod needs to pass through the guide block to act on the slider, resulting in a slow response speed of the slider and a long distance of the top plate movement, so the use stability is poor and the production is continuous Poor performance, which ultimately leads to lower mold production efficiency
