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

[0026] The present invention will be further described below in conjunction with specific embodiment:

[0027] Please refer to figure 1 , Figure 4 , Figure 6 and Figure 7 , a demoulding machine for an injection molding machine, 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;

[0028] The lower mold assembly 2 includes a lower mold 201 and a stripping plate 202;

[0029] 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;

[0030] 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;

[0031] A first sliding mechanism 3 is arranged between the lower mold...

Abstract

The invention discloses a die release machine for an injection molding machine. The die release machine comprises an upper die and a lower die assembly, wherein a cavity is formed in the upper die, and a core is arranged on the lower die assembly; the lower die assembly comprises a lower die and a die release plate; the die release plate is located between the lower die and the upper die, and thecore fixed to the lower die penetrates through a through hole in the die release plate to be matched with the cavity; a guide column arranged on the lower die penetrates through the through hole in the die release plate to form slide fit with a corresponding hole in the upper die; a first slide mechanism is arranged between the lower die and the die release plate, and the slide mechanism enables the lower die to slide relative to the die release plate; and a second slide mechanism is arranged between the die release plate and the upper die, and the slide mechanism enables the die release plateto slide relative to the upper die. The die provided by the invention is simple in structure and low in cost, and an independent ejection mechanism does not need to be arranged.

Description

technical field [0001] The invention relates to the technical field of molds, in particular to a demoulding machine for injection molding machines. 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 object of the present invention is to o...
