Inverted buckle demolding device of complex-shape product

Abstract

The invention discloses an inverted buckle demolding device of a complex-shape product. The inverted buckle demolding device comprises a first sliding block mechanism used for demolding of a first inverted buckle (1) and a second sliding block mechanism used for demolding of a second inverted buckle (2). The large end of an inclined guide column (3) in the second sliding block mechanism is connected with an upper mold plate of a mold. A second sliding block (4) is in sliding connection with the inclined guide column (3) and meanwhile is in sliding connection with a lower mold plate. A guide structure is arranged between the first sliding block mechanism and the lower mold plate, and a first sliding block (6) is in sliding connection to the second sliding block (4). The end of the first sliding block (6) is provided with a molded surface matched with the first inverted buckle (1). The end of the second sliding block (4) is provided with a molded surface matched with the second inverted buckle (2). The mold opening sequence of the mold is demolding of the first inverted buckle (1) and demolding of the second inverted buckle (2) successively. After the above structure is adopted, the phenomenon that the inverted buckles are damaged by pulling is avoided, meanwhile, the mold structure is more compact and simpler, and demolding is more ingenious and effective.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to an undercut stripping device for complex-shaped products. Background technique [0002] At present, most of the plastic products are used in auto parts, a large part of the reason is that they are easy to be formed into complex shapes at one time, such as attached figure 1 And attached figure 2 The auto part shown in , it has a panel and a gantry-type bracket protruding from the panel, a first undercut 1 inclined to the panel is provided at the edge of the panel, and a first undercut 1 is provided on the side of the beam of the gantry-type bracket facing the panel. The second undercut 2, the first undercut 1 and the second undercut 2 have different inclination directions. In other words, these undercuts cannot be directly released from the mold, and they all need to be inclined when designing the mold. Structure (in the mold design, the inclined top is the mechanism used to for...

Problems solved by technology

However, there are the following problems in the specific design of the mold: first, if the first undercut and the second undercut are made into a slanted top, since their demoulding directions are different, there will be movement interference, It is bound to destroy one of the undercut structures; secondly, if the first undercut and the second undercut are used separately for inclined roofing, on the one hand, it will increase the volume of the entire mold and make the mold structure more complicated; The size of the parts is not large, and the distance between the gantry bracket and the panel is relatively short. It is very difficult to design two slanted roof structures in such a narrow space.
