Problems solved by technology

Since it is necessary to separately add a set of ejecting mechanism dedicated to ejecting materials, the stroke space of the entire injection molding equipment will undoubtedly be increased, thereby increasing the tonnage requirements of the equipment and the production cost of the manufacturer.

Embodiment Construction

[0030] The present invention will be further described below in conjunction with specific embodiment:

[0031] Please refer to figure 1 , Figure 4 , Image 6 and Figure 7 , a delayed demoulding mold, comprising an upper mold 1 and a lower mold assembly 2, the upper mold is provided with a cavity 101, and the lower mold assembly 2 is provided with a core 6;

[0032] The lower mold assembly 2 includes a lower mold 201 and a stripping plate 202;

[0033] The stripping plate 202 is located between the lower mold 201 and the upper mold 1, and the core 6 fixed on the lower mold 201 passes through the through hole 2021 on the stripping plate 202 to cooperate with the cavity 101;

[0034] The four guide pillars 4 arranged on the lower mold 201 pass through the through holes 2022 on the stripping plate, and are slidably fitted with the corresponding holes 102 on the upper mold 1;

[0035] A first sliding mechanism 3 is arranged between the lower mold 201 and the stripping plate ...

Abstract

The invention provides a delayed demolding mold and a demolding method. The delayed demolding mold comprises an upper mold and a lower mold assembly, wherein a cavity is formed in the upper mold; a core is arranged on the lower mold assembly; the lower mold assembly comprises a lower mold and a demolding plate; the demolding plate is positioned between the lower mold and the upper mold; the core fixed on the lower mold penetrates through a through hole in the demolding plate and is matched with the cavity; a guide post arranged on the lower mold penetrates through the through hole in the demolding plate and is in sliding fit with a corresponding hole in the upper mold; a first sliding mechanism is arranged between the lower mold and the demolding plate, and due to the sliding mechanism, the lower mold can slide relative to the demolding plate; and a second sliding mechanism is arranged between the demolding plate and the upper mold, and due to the sliding mechanism, the demolding plate can slide relative to the upper mold. The mold provided by the invention is simple in structure and low in cost, and an independent ejector mechanism does not need to be arranged.

Description

technical field [0001] The invention relates to the technical field of moulds, in particular to a delayed demoulding mold structure and a demoulding method thereof. Background technique [0002] In the process of mold opening of existing injection molding machines, the lower mold generally drives the core to move out from the cavity in the upper mold, and the injection molded product is still located on the core in the lower mold. In order to take out the injection molded product in the core of the lower mold, a separate ejector mechanism must be used to eject the injection molded product from the core in the lower mold. Since it is necessary to separately add a set of ejecting mechanism dedicated to ejecting materials, the stroke space of the entire injection molding equipment will undoubtedly be increased, thereby increasing the tonnage requirement of the equipment and the production cost of the manufacturer. Contents of the invention [0003] The purpose of the present...
