A horizontal inclined top core-pulling device arranged in a horizontal slider

Abstract

The invention discloses a transverse inclined top core-pulling device arranged in a transverse slide block, which includes a transverse slide block (1), a pin (11), an inclined top rod (2), an inverted core block (21), a positioning Nest (22), stopper (23), inclined top seat (3), and containment groove (31). The invention adopts the method of arranging the inclined ejector rod and the undercut core block in the transverse slide block. When the mold is opened, while the inclined guide pillar drives the transverse slide block for transverse demolding, the inclined ejector rod and the undercut core block are placed on the stopper. The technical solution is to slide and extend the transverse slider obliquely under restraint, so that the undercut core block can be ejected from the product in the direction orthogonal to the ejection direction of the transverse slider, which overcomes the existing technology. There are problems and shortcomings such as complex structure, high cost, low efficiency and easy production of scrap products. By arranging the inclined top mechanism in the horizontal slider, the injection mold with horizontal and inclined core pulling and demoulding that makes the product upside down has achieved a simplified structure and The purpose is to reduce costs, improve demoulding efficiency and avoid waste products.

Description

Technical field [0001] The invention relates to an inclined top core-pulling device of an injection mold, in particular to a horizontal sliding block that is used to demold the core block of a molded product upside down with a horizontal sliding block, and the horizontal inclined top is drawn out and arranged in the horizontal sliding block. Inclined top core pulling device. Background technique [0002] The core-pulling and demolding of the injection mold is divided into longitudinal, transverse and oblique directions. The so-called longitudinal direction is along the opening and closing direction of the injection mold, the so-called transverse direction is the direction orthogonal to the longitudinal direction, and the direction between the longitudinal direction and the transverse direction is oblique. to. [0003] In the horizontal slider, the surface where the diagonal direction axis is located is parallel to the surface where the demolding direction axis of the horizontal sl...

Problems solved by technology

[0004] The inclined top core-pulling device is usually installed in the movable or fixed platen of the injection mold. For the undercut inclined core-pulling in which the axis of the inclined-drawing direction axis of the inverted core block is parallel to the transverse surface of the mould, the prior art adopts a dynamic An oil cylinder is set on the formwork to carry out the reverse buckle core-pulling first, and then divide and open the mold to eject the product from the mold; its structure is complex, and the demoulding process of core-pulling, mold opening, and ejecting the product is long and inefficient; the supporting oil cylinder and its control device, so that the cost of the mold is high; in addition, if there is an error in the coordinated control of the core-pulling action of the oil cylinder and the parting action of the mold, the product will be scrapped. Therefore, the existing technology has complex structure, high cost, low efficiency, and easy production. Waste problems and deficiencies
