An Outer Buckle Mechanism for Precise Stroke Control

Abstract

The invention discloses an external buckle mechanism for precise stroke control, comprising a stroke control mechanism and a sequence control mechanism. The stroke control mechanism is used to precisely control the stroke of a mold when the mold is opened, so that the mold can be opened smoothly at the same time. The plastic parts in the mold cavity will not be damaged; the sequence control mechanism is used to control the mold opening sequence of each mold opening surface of the mold, so as to ensure that the various parts of the mold act according to the set sequence; the stroke control mechanism It includes a trigger base and a trigger rod, and the trigger rod is partially slidably sleeved in the trigger base; the sequence control mechanism includes a first elastic block telescopically installed on the nozzle push plate and a telescopic The second elastic block is movably installed on the A plate; the component structure of the present invention and the cooperation relationship between them are simple, the structural strength and stability are good, and the mold opening distance of the mold opening surface and the mold opening and closing sequence can be accurately controlled. control to meet the production needs of different plastic products.

Description

technical field [0001] The invention relates to a mold external clamp mechanism, which is especially suitable for an injection mold external clamp mechanism capable of realizing more than two mold opening operations, and belongs to the technical field of injection molds. Background technique [0002] In injection molds, for plastic products with relatively simple shapes, generally only one mold opening is required to remove the formed plastic products from the mold, while for plastic products with complex structures or larger shapes, one-time The method of mold opening may not be able to remove the complex parts of the plastic product smoothly. If the mold is opened forcibly, it will damage / damage the complex parts or appearance of the plastic product, resulting in defective products. Therefore, for complex structures or relatively large shapes Large plastic products often adopt the method of secondary mold opening to open the mold when opening the mold. The first mold openi...
