Description

Technical Field

[0001] The present application relates to the technical field of mold parts, and more specifically, to an airway plate structure. Background Art

[0002] The preform mold is generally composed of a core plate, a separation plate and a cavity plate, in which the core plate and the separation plate serve as a movable mold plate, and the cavity plate serves as a fixed mold plate. The movable mold plate is molded together with the fixed mold plate to form a mold cavity, and the preform is manufactured by injecting the melt into the mold cavity to form the preform.

[0003] In order to ensure the quality of the preform, an air groove is generally provided on the preform mold to discharge the gas generated in the mold cavity when the preform is formed. However, dust is generated when the preform melt is injected, and the dust adheres to the air groove when the preform melt is injected, thereby causing poor exhaust and affecting the quality of the preform.

[0004] To address the above problem, a slide plate is currently provided and connected to a separation plate. Driven by the cylinder, the slide plate drives the separation plate to move, so that gaps are formed between the separation plate and the core plate and the cavity plate respectively. The gaps are connected to the mold cavity and the air groove, and the dust on the air groove is then removed by means of overflow flash.

[0005] Among them, it is foreseeable that the cylinder generally needs to be connected to a hose and connected to an external air source through the hose to drive the cylinder to move. However, the connection of the hose not only affects the appearance, but also has a limited lifespan, and the hose cannot be bent too much, that is, the hose requires a certain installation space, especially when the installation location is limited, the method of connecting through the hose is obviously not practical.

[0006] Therefore, the prior art needs to be improved. Utility Model Content

[0041] The preform mold is generally composed of a core plate, a separation plate and a cavity plate, in which the core plate and the separation plate serve as a movable mold plate, and the cavity plate serves as a fixed mold plate. The movable mold plate is molded together with the fixed mold plate to form a mold cavity, and the preform is manufactured by injecting the melt into the mold cavity to form the preform.

[0042] In order to ensure the quality of the preform, an air groove is generally provided on the preform mold to discharge the gas generated in the mold cavity when the preform is formed. However, dust is generated when the preform melt is injected, and the dust adheres to the air groove when the preform melt is injected, thereby causing poor exhaust and affecting the quality of the preform.

[0043] To address the above problem, a slide plate is currently provided and connected to a separation plate. Driven by the cylinder, the slide plate drives the separation plate to move, so that gaps are formed between the separation plate and the core plate and the cavity plate respectively. The gaps are connected to the mold cavity and the air groove, and the dust on the air groove is then removed by means of overflow flash.

[0044] Among them, it is foreseeable that the cylinder generally needs to be connected to a hose and connected to an external air source through the hose to drive the cylinder to move. However, the connection of the hose not only affects the appearance, but also has a limited lifespan, and the hose cannot be bent too much, that is, the hose requires a certain installation space, especially when the installation location is limited, the method of connecting through the hose is obviously not practical.

[0045] For this purpose, see Figure 1 and Figure 2 An airway plate structure provided in an embodiment of the present application includes an airway plate body 1, in which a first channel (not shown in the figure) and a second channel (not shown in the figure) that are not connected are opened, an air outlet 11 of the first channel is connected to a first port (not shown in the figure) of a cylinder 2, and an air outlet 12 of the second channel is connected to a second port (not shown in the figure) of the cylinder 2, wherein the first port is arranged at one end of the cylinder 2, and the second port is arranged at the other end of the cylinder 2, that is, two external air sources respectively pass through the first channel and the second channel of the airway plate to supply air to the first port and the second port of the cylinder 2 to drive the cylinder 2 to extend or retract.

[0046] In this embodiment, an airway plate body 1 is provided, and two non-interconnected first and second channels are opened in the airway plate body 1.
