Description

Technical Field

[0001] The utility model relates to the field of an inclined top core-retracting mechanism for an inclined hole, in particular to an inclined top core-retracting mechanism for an inclined hole. Background Art

[0002] The inclined ejector core-removing mechanism for inclined holes is a common structure in injection molds. When the mold is closed, the inclined ejector is at the position of the core to form an inclined hole in the plastic part. When the plastic part is molded, the mold is opened and the inclined ejector moves in an oblique direction under the action of the ejection mechanism, thereby extracting the core from the plastic part. It is used to withdraw the core in the inclined hole after the plastic part is molded, so as to smoothly remove the plastic part.

[0003] When most inclined ejector core-retracting mechanisms are in use, the inclined holes of the product cannot be demoulded normally. Conventional designs require a spring plate, but the design of a spring plate will be unstable when the mold is large, which may lead to demoulding difficulties, core jamming or damage, causing production delays and equipment failures. In addition, the production cost is too high, which increases the amount of materials required for the mechanism, thereby increasing the cost of raw materials.

[0004] Therefore, the utility model provides a slanted ejector core-retracting mechanism for an inclined hole to solve the problems raised in the above-mentioned background technology. Utility Model Content
