Description

Technical Field

[0001] The present application relates to the technical field of mold parts, and more specifically, to a cavity plate 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, our company has set a slide plate on the cavity plate and connected the slide plate to the separation plate. Driven by the cylinder, the slide plate will drive the separation plate to move, so that a gap is formed between the separation plate and the core plate and the cavity plate respectively. The gap will be connected to the mold cavity and the air groove, and then the dust on the air groove will be taken away by overflow flash.

[0005] However, since the cavity plate needs to have multiple cylinders, and the multiple cylinders are spread throughout the entire cavity plate, it can be foreseen that each cylinder is generally provided with two openings, and the two openings are connected to the corresponding external air source through air pipes. In this way, the air pipes connected to the multiple cylinders on the cavity plate will be entangled with each other, thereby causing the entire cavity plate structure to be chaotic and difficult to repair.

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

[0045] 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.

[0046] 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.

[0047] 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.

[0048] 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.

[0049] To address the above problem, our company has set a slide plate on the cavity plate and connected the slide plate to the separation plate. Driven by the cylinder, the slide plate will drive the separation plate to move, so that a gap is formed between the separation plate and the core plate and the cavity plate respectively. The gap will be connected to the mold cavity and the air groove, and then the dust on the air groove will be taken away by overflow flash.

[0050] However, since the cavity plate needs to have multiple cylinders, and the multiple cylinders are spread throughout the entire cavity plate, it can be foreseen that each cylinder is generally provided with two openings, and the two openings are connected to the corresponding external air source through air pipes. In this way, the air pipes connected to the multiple cylinders on the cavity plate will be entangled with each other, thereby causing the entire cavity plate structure to be chaotic and difficult to repair.

[0051] See also Figure 1 , Figure 4 and Figure 5A cavity plate structure provided in a first aspect of an embodiment of the present application comprises a cavity plate body 1 and a plurality of cylinders 2, wherein the cavity plate body 1 is provided with a first gas path (not shown in the figure) and a second gas path (not shown in the figure), and the plurality of cylinders 2 are arranged on the cavity plate body 1, and each of the cylinders 2 is provided with a first port and a second port, and the cavity plate body 1 is provided with a first gas path air outlet 11 and a second gas path air outlet 12 corresponding to the cylinder 2 on one surface of the cylinder 2, the first gas path air outlets 11 are connected to each other through the first gas path, and the second gas path air outlets 12 are connected to each other through the second gas path, the first gas path air outlet 11 is connected to the corresponding first port, and the second gas path air outlet 12 is connected to the corresponding second port.

[0052] It can be foreseen that the present embodiment opens two air paths (a first air path and a second air path) directly on one surface of the cavity plate body 1 located on the cylinder 2, and opens a first air path outlet 11 and a second air path outlet 12 corresponding to each cylinder 2 in the two air paths, so that the air source can be directly introduced from the cavity plate body 1 to the first port and the second port of the cylinder 2 for connection. Compared with pulling the air pipe from the outside to the cylinder 2 of the cavity plate body 1, the present embodiment shortens the distance connected to the cylinder 2, thereby making the structure simple and uncluttered, and easy to repair.

[0053] See also Figure 1 and Figure 2 In one embodiment, the cavity plate structure further includes a connecting component 3, which is disposed between the cavity plate body 1 and the cylinder 2 and connects the cavity plate body 1 and the cylinder 2.

[0054] In one embodiment, the connecting assembly 3 includes a first connecting main pipe and a second connecting main pipe, a plurality of first branch pipes are extended from the first connecting main pipe, one end of the first branch pipe is connected to the corresponding first gas circuit outlet 11, and the other end is connected to the corresponding first port, and a plurality of second branch pipes are extended from the second connecting main pipe, one end of the second branch pipe is connected to the corresponding second gas circuit outlet 12, and the other end is connected to the corresponding second port.

[0055] See also Figure 1 and Figure 2 In another embodiment, the connecting assembly 3 includes a plurality of airway plates 31, and the plurality of airway plates 31 correspond one-to-one to the plurality of cylinders 2. Each of the airway plates 31 is provided with a first channel and a second channel, and the first channel is respectively connected to the corresponding first air path outlet 11 and the first port, and the second channel is respectively connected to the corresponding second air path outlet 12 and the second port.

[0056] See also Figure 1 and Figure 3 In one embodiment, a first gas circuit air inlet 13 and a second gas circuit air inlet 14 are provided on the cavity plate body 1, and the cavity plate structure also includes a first plug connector 4 and a second plug connector 5, the first plug connector 4 is arranged in the first gas circuit air inlet 13, the first gas circuit is connected to a first external gas source through the first plug connector 4, the second plug connector 5 is arranged in the second gas circuit air inlet 14, and the second gas circuit is connected to a second external gas source through the second plug connector 5.

[0057] For further information, see Figure 1 and Figure 6 In one embodiment, the sizes of the first plug connector 4 and the plug connector are different. For example, the size of the first plug connector 4 can be larger than the size of the second plug connector 5. This embodiment prevents the first plug connector 4 and the second plug connector 5 from being connected to the wrong position by setting the sizes of the first plug connector 4 and the second plug connector 5 to be different, thereby playing a fool-proof role.

[0058] See also Figure 1 In one embodiment, a cooling layer is provided in the cavity plate body 1, and the cavity plate structure further includes a first cooling component 6, which is respectively connected to the cooling layer and an external cooling source, and the cooling layer covers the position of the mold cavity on the cavity plate body 1.

[0059] See also Figure 1 In one embodiment, the cooling layer includes a first cooling water circuit (not shown in the figure) and a second cooling water circuit (not shown in the figure), the first cooling water circuit is arranged on one side of the cavity plate body 1, and the second cooling water circuit is arranged on the other side of the cavity plate body 1, the first cooling assembly 6 includes a first water inlet pipe joint 61, a second water inlet pipe joint 62, a first water outlet pipe joint 63 and a second water outlet pipe joint 64, the first water inlet pipe joint 61 is arranged at the inlet end of the cavity plate body 1 located at the first cooling water circuit, the second water inlet pipe joint 62 is arranged at the inlet end of the cavity plate body 1 located at the second cooling water circuit, the first water outlet pipe joint 63 is arranged at the outlet end of the cavity plate body 1 located at the first cooling water circuit, and the second water outlet pipe joint 64 is arranged at the outlet end of the cavity plate body 1 located at the second cooling water circuit.

[0060] That is to say, the first cooling water channel and the second cooling water channel are independently controlled respectively. Compared with merging the first cooling water channel and the second cooling water channel into one water channel for control, this embodiment can enhance the cooling effect of the cooling layer by independently controlling the first cooling water channel and the second cooling water channel to increase the hydraulic force.

[0061] See also Figure 1 and Figure 2 In one embodiment, a plurality of supporting columns 7 are arranged on one side of the cavity plate body 1. When the separation plate is driven to be molded together with the cavity plate body 1, the supporting columns 7 are against the separation plate. Through the arrangement of the supporting columns 7, this embodiment can not only assist the separation plate to be molded together with the cavity plate body 1, but also bear the force applied to the cavity plate body 1 during the mold closing, thereby playing a stable supporting role. The plurality of supporting columns 7 are of different sizes to avoid other structures.

[0062] See also Figure 6 In one embodiment, a plurality of wire installation grooves 8 are provided on one side of the cavity plate body 1. The plurality of wire installation grooves 8 are arranged in parallel and are used to place wires. A plurality of wire pressing members 9 are arranged above each of the wire installation grooves 8. The wire pressing members 9 may be wire pressing plates or wire pressing lines, and may be installed on one side of the cavity plate body 1 located on the wire installation groove 8. The wire pressing members 9 are used to press the wires in the wire installation grooves 8 to prevent the wires in the wire installation grooves 8 from being too messy. In other words, the arrangement of the wire pressing members 9 can play a role in tidying up the wires.

[0063] A second aspect of an embodiment of the present application provides a preform mold, comprising the cavity plate structure as described above.

[0064] In summary, the present application provides a cavity plate structure and a preform mold, comprising a cavity plate body 1 and a plurality of cylinders 2, the cavity plate body 1 being provided with a first air path and a second air path, the plurality of cylinders 2 being arranged on the cavity plate body 1, each of the cylinders 2 being provided with a first port and a second port, the cavity plate body 1 being located on one surface of the cylinder 2 and being provided with a first air path outlet 11 and a second air path outlet 12 corresponding to the cylinder 2, the first air path outlets 11 being connected to each other through the first air path, the second air path outlets 12 being connected to each other through the second air path, the first air path outlet 11 being connected to the corresponding first port, and the second air path outlet 12 being connected to the corresponding second port. It can be foreseen that the present application opens two air paths (a first air path and a second air path) directly on one surface of the cavity plate body 1 located on the cylinder 2, and opens a first air path outlet 11 and a second air path outlet 12 corresponding to each cylinder 2 in the two air paths, so that the air source can be directly introduced from the cavity plate body 1 to the first port and the second port of the cylinder 2 for connection.
