Problems solved by technology

[0002] At present, most simple preform injection molding systems rely on the hydraulic ejector mechanism to eject the preform, and the ejected preform directly falls on the conveyor belt under the machine, and is transported to the next station by the conveyor belt. The ejection and demoulding method is likely to cause product drop damage and deformation due to excessive temperature of the product
[0003] In view of the above problems, the existing technology proposes a preform removal system with a manipulator. This system uses multiple independent valve bodies to form a vacuum preform removal air circuit. The valve bodies are connected by various pipelines, and there is a large airflow resistance. , large vacuum loss, large footprint, cumbersome installation, low volumetric efficiency and high energy consumption, most of them need to increase the vacuum pump to ensure the vacuum degree, which cannot fundamentally solve the problem

Embodiment 1

[0042] Such as Figure 1-Figure 5 As shown, this embodiment provides a combined air valve, which includes a combined valve body 1 , several main valve core assemblies and several pilot valves 2 . Wherein, the combined valve body 1 is used as the base body of the combined gas valve, on which several installation holes and several gas pipes are arranged, and the gas pipes are used for connecting external actuators. A plurality of main valve core couples are arranged in the mounting holes one by one, and the main valve core couples are used to realize the on-off of the gas circuit. A plurality of pilot valves 2 are set corresponding to the above-mentioned main spool couples one by one and are detachably connected to the combined valve body 1 .

[0043] Specifically, as figure 1 As shown, the main spool assembly includes the main spool 3 and the main valve body, the main spool 3 can move up and down in the main valve body, and the movement of the piston-type main spool 3 realize...

Embodiment 2

[0053] This embodiment also provides an assembly method of the combined air valve, which is efficient, simple, and easy to maintain and replace.

[0054] The assembling method of this combined air valve comprises the steps:

[0055] S1: Provide combined valve body 1 with mounting holes and gas piping.

[0056] S2: Install the main valve body 5 of the lower seat to the lower part of the installation hole by means of the positioning steps, buckle the lower cover plate 6 of the valve body corresponding to the main valve body 5 of the lower seat on the lower surface of the combined valve body 1, and connect them through fasteners.

[0057] S3: Insert the main valve core 3 into the installation hole, so that the lower end of the main valve core 3 is connected with the main valve body 5 of the lower seat.

[0058] S4: Install the main valve body 4 on the upper seat to the upper part of the installation hole by means of the positioning step, so that the main valve body 4 on the uppe...

Abstract

The invention relates to the technical field of combined valves and discloses a combined gas valve and an assembling method thereof. The combined gas valve comprises a combined valve body, a pluralityof main valve element couple parts and a plurality of pilot valves. The combined valve body is provided with a plurality of installing holes and a plurality of gas pipelines. The gas pipelines are used for being connected with an execution mechanism. The main valve element couple parts are arranged in the installing holes in a one-to-one corresponding manner. The main valve element couple parts are used for achieving on-off of a gas loop. The pilot valves and the main valve element couple parts are arranged in a one-to-one corresponding manner, and are detachably connected to the combined valve body. The combined gas valve is high in blank sucking and pouring working efficiency, energy is saved, the occupied area is small, installing is simple, the lift is long, and maintaining and replacing are convenient. The assembling method of the combined gas valve is simple and efficient, and maintaining and replacing are easy.
