Problems solved by technology

[0002] The injection mold is inclined in one direction for all the ribs of the product. The existing technology is to tilt the top plate in the same direction as the inclined direction of the product ribs, and use the oil cylinder to push the top plate obliquely to eject; the disadvantage of this method is that the mold cannot be made One mold has multiple holes, and it cannot be made into a mold with other products perpendicular to the ribs, which makes the mold manufacturing cost high and the product production efficiency low. Therefore, the existing technology cannot meet the increasing production requirements.

Embodiment Construction

[0010] Figure 1-2 Shown is an explanatory diagram related to the present invention; a mechanism for an injection mold auxiliary thimble ejecting obliquely, including a sliding plate 1, a sliding pressure plate 11, a guide rod 2, an ejector rod 3, and a sliding seat 4.

[0011] The sliding plate 1 is fixed together with the sliding pressure plate 11, and can slide obliquely in the sliding seat 4, such as figure 1 shown.

[0012] The upper section of the guide rod 2 is fixed in the upper fixed block 07, the middle is in the sliding plate 1, and the lower end is fixed in the lower fixed block 06, as figure 1 shown.

[0013] The oblique angle of the ejector rod 3 is consistent with the oblique rib position 011, the upper end of the ejector rod 3 is in the movable mold core 02, and is in contact with the product 01, and the lower end of the ejector rod 3 is fixed on the slide plate 1 and the slide platen 11 between, such as figure 1 shown.

[0014] Described sliding seat 4 is...

Abstract

The invention discloses a mechanism assisting in oblique ejection of a centre through an injection mold. The mechanism comprises a sliding plate, a guide rod, ejector rods and a sliding base. By means of the mechanism composed of the components, during ejection, the oblique guide rod is used for controlling the motion condition of the sliding plate in the sliding base, and the centre fixed to the sliding plate can eject out a product in the oblique direction of the guide rod; and therefore, overall oblique of an ejector plate is prevented, normal work of other pit ejection mechanisms is effectively guaranteed, the one-mold multi-pit aim is achieved, and production benefits are improved.

Description

technical field [0001] The invention relates to an injection mold, in particular to a mechanism for an injection mold to assist ejector pins in oblique ejection. Background technique [0002] The injection mold is inclined in one direction for all the ribs of the product. The existing technology is to tilt the top plate in the same direction as the inclined direction of the product ribs, and use the oil cylinder to push the top plate obliquely to eject; the disadvantage of this method is that the mold cannot be made Form a mold with multiple cavities, let alone make a pair of molds with other products perpendicular to the ribs, which makes the mold manufacturing cost high and the product production efficiency low. Therefore, the existing technology cannot meet the increasing production requirements. Contents of the invention [0003] The technical problem to be solved by the present invention is to provide a mechanism for assisting ejector pins in injection molds to eject ...
