Description

Technical Field

[0001] The present application relates to the technical field of mold parts, and more specifically, to a cavity plate fool-proof structure and a preform mold. 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.

[0039] In order to make the technical problems, technical solutions and beneficial effects to be solved by the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0040] It should be noted that when a component is referred to as being "fixed on" or "disposed on" another component, it may be directly or indirectly located on the other component. When a component is referred to as being "connected to" another component, it may be directly or indirectly connected to the other component. The directions or positions indicated by the terms "upper", "lower", "left", "right", "front", "back", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc. are based on the directions or positions shown in the accompanying drawings and are only for the convenience of description and cannot be understood as limitations on the present technical solution. The terms "first" and "second" are only used for the convenience of description and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features. "Multiple" means two or more, unless otherwise clearly and specifically defined.

[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 can be foreseen that the cylinder is generally provided with two passages, and the two passages are connected to two external air sources through two plug-in tubes respectively to drive the extension and contraction of the cylinder respectively. However, the two existing plug-in tubes are usually configured the same, which may easily cause the two plug-in tubes to be plugged in reverse, resulting in errors in the cylinder movement, thereby causing errors in the dust removal work.

[0045] See also Figure 1 and Figure 4 A cavity plate fool-proof structure provided in a first aspect of an embodiment of the present application includes a first plug connector 11 and a second plug connector 12, wherein the first plug connector 11 is arranged in a first port (not shown in the figure) of the cylinder assembly 2, and a first external air source is connected to the first port through the first plug connector 11, and the second plug connector 12 is arranged in a second port (not shown in the figure) of the cylinder assembly 2, and a second external air source is connected to the second port through the second plug connector 12, and the first plug connector 11 is different from the second plug connector 12. That is, in this embodiment, by setting the first plug connector 11 and the second plug connector 12 differently, the first plug connector 11 and the second plug connector 12 can be clearly distinguished, thereby avoiding the problem of incorrect movement of the cylinder 21 caused by the first plug connector 11 and the second plug connector 12 being plugged in reverse, thereby avoiding the problem of errors in dust removal work.

[0046] In one embodiment, the shape of the first plug connector 11 and the shape of the second plug connector 12 may be set to be different, so that the first plug connector 11 and the second plug connector 12 can be clearly distinguished.

[0047] See also Figure 1 and Figure 2 In another embodiment, the size of the first plug connector 11 is different from the size of the second plug connector 12 so that the first plug connector 11 and the second plug connector 12 can be clearly distinguished.

[0048] See also Figure 1In one embodiment, the cylinder assembly 2 includes a plurality of cylinders 21, each cylinder 21 is provided with a first port and a second port, and when all cylinders 21 are used to extend or retract at the same time, in order to facilitate the simultaneous control of the plurality of cylinders 21, the cavity plate foolproof structure also includes a cavity plate body 3 and a connecting assembly 4, a first air circuit (not shown in the figure) and a second air circuit (not shown in the figure) are provided in the cavity plate body 3, the first plug connector 11 is provided in the first air circuit air inlet of the first air circuit, a first external air source is connected to the first air circuit through the first plug connector 11, the second plug connector 12 is provided in the second air circuit air inlet of the second air circuit, a second external power source is connected to the second air circuit through the second plug connector 12, and the connecting assembly 4 corresponds to connecting the first port of the cylinder 21 and the first air circuit, and the second port and the second air circuit.

[0049] Compared with each cylinder 21 being connected with the first plug connector 11 and the second plug connector 12, in this embodiment, by opening the first gas path and the second gas path on the cavity plate body 3, and respectively arranging the first plug connector 11 and the second plug connector 12 in the first gas path air inlet of the first gas path and the second gas path air inlet of the second gas path, multiple cylinders 21 can be connected to the cavity plate body 3 through the connecting component 4, which not only saves the number of plug connectors, but also makes the entire structure simpler.

[0050] In one embodiment, the connecting assembly 4 may include a first connecting main pipe (not shown in the figure) and a second connecting main pipe (not shown in the figure), the first connecting main pipe is extended with a plurality of first branch pipes, the cavity plate body 3 is provided with a first gas circuit outlet 31 corresponding to the first branch pipe, one end of the first branch pipe is connected to the corresponding first gas circuit outlet 31, and the other end is connected to the corresponding first port, the second connecting main pipe is extended with a plurality of second branch pipes, the second gas circuit is provided with a second gas circuit outlet 32 ​​corresponding to the second branch pipe, one end of the second branch pipe is connected to the corresponding second gas circuit outlet 32, and the other end is connected to the corresponding second port.

Since the airway plate 41 has a certain hardness, compared with the air pipe connecting the cylinder 21, the airway plate 41 is connected to the cylinder 21 through the first channel and the second channel, and the shapes of the first channel and the second channel can be arbitrarily bent, and the first channel and the second channel will be hidden in the airway plate 41, thereby saving the installation space of the airway plate 41 and making the entire structure neat and tidy to install without being messy.

[0053] Since the first gas outlet 31 and the second gas outlet 32 ​​on the cavity plate body 3 are very dense and the space is limited, in order to ensure the structural strength of the gas outlet on the cavity plate body 3 and to ensure that the airway plate 41 is easy to process and the mold is beautiful, the appearance of the airway plate 41 is consistent, and a foolproof setting is made for the installation method of the airway plate 41, wherein, refer to Figure 1 and Figure 2 In one embodiment, a plurality of the airway plates 41 are arrayed on the cavity plate body 3, and the installation positions of two adjacent rows of airway plates 41 located in the middle of the cavity plate body 3 are set differently, so that the mold will not be installed incorrectly during assembly.
