Abstract

One or more embodiments of the invention provide an oil cylinder, rack and large-stroke secondary sliding block mold structure and a mold assembly. An oil cylinder and a sliding block mechanism are arranged, a first rack is connected to the piston end of the oil cylinder, a sliding block seat is arranged in a sliding block assembly, a second rack and a gear assembly are installed at the bottom of the sliding block seat, the upper portion of the gear assembly is engaged with the second rack, and the lower portion of the gear assembly is engaged with the first rack. When the oil cylinder drives a piston to drive the first rack to move, the gear assembly drives the second rack to move, then the sliding block mechanism is driven to move in the mold stripping direction, and large-stroke mold stripping is achieved. A sliding block insert and a sliding block moving part are arranged, a guide rail is arranged between the sliding block moving part and the sliding block insert, and the sliding block moving part can move along the guide rail. During mold stripping, mold stripping of the sliding block insert is firstly conducted, then mold stripping of the sliding block moving part is conducted under the driving of limiting screws, secondary sliding block mold stripping is completed, and the problem that in the prior art, it is difficult to conduct mold stripping on a product with a large inner opening and a small outer opening is solved.

Description

technical field [0001] One or more embodiments of this specification relate to the field of mold technology, and in particular to a mold structure and mold assembly of a large stroke secondary slider of an oil cylinder rack. Background technique [0002] Molds are various molds and tools used in industrial production for injection molding, blow molding, extrusion, die-casting or forging forming, smelting, stamping and other methods to obtain the required products; [0003] For products with openings, the mold usually needs to be demolded by means of cylinder transmission, but for products with large strokes, high inside and low outside, that is, products with large inner openings and small outer openings, It is difficult to demould, and the existing demoulding methods often require complicated procedures and low efficiency. Contents of the invention [0004] In view of this, the purpose of one or more embodiments of this specification is to propose a mold structure and mo...
