Embodiment 1

[0015] Example 1, such as figure 1 Shown, the preform injection mold of a kind of injection blowing machine, this injection blowing machine comprises three sets of mutual injection molds, blow molds and debottle moulds, and this blow mold comprises lower blow mold 9 and upper blow mold Mold 8, the injection mold comprises the lower injection mold that is fixed on the frame; The upper injection mold 1 that vertical sliding is installed on the frame; Rotation is installed on the turret 7 on the frame, and this turret 7 is lifted by Driven by a power unit; the turret 7 is provided with three mandrels 6 that form 120° with each other. The lower injection mold includes a lower injection mold body, the lower injection mold body is fixed on the frame, the lower injection mold body is provided with a sliding platform that facilitates the sliding of the injection molding cavity 5, and the position is matched with the upper neck block 11 lower neck mass. The upper injection mold 1 inc...

Embodiment 2

[0019] Such as figure 2 As shown, this figure describes the structural schematic diagram of the injection mold cavity when the mold is closed. The injection mold described in this embodiment is basically the same as the structure in Embodiment 1, except that the injection cavity 5 and the injection table 3 are fixed. connect. For example, common fixing methods such as bolt and nut connections can be used.

Abstract

The invention discloses a preform injection mold of an injection blowing machine, which comprises a lower injection mold fixed on a frame; an upper injection mold vertically slidably mounted on the frame; a turret mounted on the frame by rotation. The turret is driven by a vertical lifting power device; the turret is equipped with three mandrels at an angle of 120° to each other, and also includes an injection cavity that is horizontally slidably installed on the lower injection mold, and the injection cavity is slidably installed on the frame The injection molding platform is connected; the injection port of the injection molding cavity is docked with the injection port of the injection molding platform; the injection molding platform is driven and slid by the injection platform driving device so that the injection cavity and the mandrel are set or separated, and the upper injection mold is connected to the mandrel. The upper mold driving device is connected, and the upper mold driving device drives the upper injection mold to move down and close the lower injection mold to cover the injection cavity and the mandrel. The mold can reduce the clamping force requirements of the equipment and improve the surface finish of the product.

Description

technical field [0001] The invention relates to a preform injection mold, in particular to a preform injection mold for an injection blowing machine. Background technique [0002] The injection blowing machine is a kind of equipment that integrates injection molding, blow molding and bottle removal. The injection mold, blow molding mold and bottle removal mold of the machine are respectively arranged on the outer periphery of the turret at a 120° circle. The mandrels at 120° to each other, the turret can be controlled to rotate, and can also be lifted at the same time, while the injection mold includes a fixed lower injection mold and a movable upper injection mold, the lower end surface of the upper injection mold and the bottom of the lower injection mold The upper end surface is provided with injection molding cavities that cooperate with each other. In the initial state, the upper injection mold and the lower injection mold are opened, the turret rises between the upper ...
