Description

Technical Field

[0001] This utility model relates to an industrial pipeline mold, belonging to the field of mold technology. Background Technology

[0002] During mold manufacturing, a draft angle is designed to allow the product to be easily removed from the mold. While this facilitates demolding, it reduces the product's baseline wall thickness, thus decreasing the strength of the product's opening. Larger diameter products require greater resistance to internal wall pressure, and the greater the thickness removed during drafting. Therefore, this can potentially impact the product's lifespan after installation in a real-world application.

[0003] It is evident that, in order to avoid affecting the product's service life, there is an urgent need for an industrial pipe mold that can achieve demolding without designing a draft angle. Utility Model Content

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances. Example

[0029] like Figure 1 As shown, this embodiment provides an industrial pipe mold, including a male template 1, a female template 2, an upper fixed plate 3, and a first opening / closing device assembly. The male template 1, female template 2, and upper fixed plate 3 are stacked from bottom to top. The male template 1 and female template 2 are connected by the first opening / closing device assembly.

[0030] The first opening and closing device assembly is slidably installed in the female template 2 and the male template 1. One end of the first opening and closing device assembly is fixed to the upper fixed plate 3, and the other end of the first opening and closing device assembly is slidably installed in the male template 1.

[0031] The first opening and closing device assembly slides within a defined range between the female template 2 and the male template 1.

[0032] In the above technical solution, by using the first opening and closing device assembly in conjunction with the male template 1, the female template 2 and the first fixing plate 3, when the mold is opened, the first opening and closing device assembly can cooperate with the machine at the female template 2 and the male template 1 to achieve demolding without draft angle. Example

[0033] like Figures 1-5 As shown, the industrial pipe mold provided in this embodiment differs from the industrial pipe mold provided in Embodiment 1 in that:

[0034] The first opening and closing device assembly includes a first opening and closing device pull rod 4, a first opening and closing device extension rod 5, and a first opening and closing device body. The first opening and closing device pull rod 4 and the first opening and closing device extension rod 5 are installed on the upper and lower sides of the first opening and closing device body.

[0035] One end of the first opener / closer lever 4 is connected to the first opener / closer body, and the other end is fixed to the upper fixing plate 3;

[0036] One end of the extension rod 5 of the first opener / closer is connected to the main body of the first opener / closer, and the other end is slidably connected to the template 1.

[0037] It also includes a second opening and closing device assembly and a male mold pad 6. The male mold pad 6 is installed on the side of the male mold 1 away from the female mold 2. The second opening and closing device assembly is slidably installed inside the male mold 1. The second opening and closing device assembly includes a second opening and closing device body and a second opening and closing device pull rod 7. One end of the second opening and closing device body is inserted into the female mold 2, and the other end is connected to the second opening and closing device pull rod 7. The other end of the second opening and closing device pull rod 7 is fixed to the male mold pad 6.

[0038] It also includes mold feet 8, which are installed on the side of the male mold pad 6 away from the male mold plate 1.

[0039] It also includes a return pin 9, which is fixed to the male template 1 and slidably installed in the male mold pad 6 and the mold foot 8. The upper end face of the return pin 9 and the upper end face of the male template 1 are located on the same horizontal plane.

[0040] It also includes a lower ejector plate 10, which is fixed to the bottom end of the return pin 9 and is used to connect the return pin 9 and the drive mechanism.

[0041] It also includes a lower fixing plate 11, which is fixed to the side of the mold foot 8 away from the male mold pad 6.

[0042] To facilitate the opening and closing of the mother template 2 and the upper fixed plate 3, an auxiliary mold opening spring 12 is also included. The pull spring 12 is disposed on the outer surface of the upper end of the pull rod 4 of the first opener and closer, and the pull spring 12 is fixed to the mother template 2.

[0043] The fixed mold side and the moving mold side of the plastic mold are fixed to the fixed platen and the moving platen of the injection molding machine, respectively. The opening and closing power of the moving mold side comes from the reciprocating motion of the moving platen of the injection molding machine. When the fixed mold side reaches the designated position, the ejector roller on the injection molding machine passes through the ejector roller hole of the lower fixed plate 11, acts on the lower ejector plate 10, and pushes the ejector plate 10 forward to complete the entire ejection process.

[0044] The mold opening process of the mold provided in this embodiment will be described below with reference to the accompanying drawings. Figure 1 As shown, the mold is now in the closed state, and the molding, filling, cooling, and maintenance have been completed. Figure 2 As shown, the mold is in its first opening state. The first opening / closing lever 4 has completed its stroke, and the lever mounting plate is in contact with the upper fixed plate 3. Under the action of external force from the machine tool, and with the assistance of the compression and rebound force of the lever spring 12, the upper fixed plate 3 achieves the first mold separation, completing the core pulling of the inner hole insert of the female mold product. Figure 3 As shown, the mold is in the second opening state. The first opening / closing device extension rod 5 has completed its stroke, the pull rod platform is in contact with the mother mold plate 2, and the upper fixing plate 3 can no longer move. Under the action of the first opening / closing device extension rod 5, the machine continues to pull the mother mold plate 2 to complete the peeling of the outer mold core of the mother mold plate 2. Figure 4 As shown, the mold is in its third opening state. The second opening / closing device pull rod 7 has completed its stroke, and the pull rod platform is now in contact with the male mold plate 1. The side plate of the female mold plate 2 can no longer move relative to the mold. Under the action of the third opening / closing device 7, the machine tool drives the entire male mold plate 1 and the ejection system to move, completing the core pulling of the male mold product's inner hole insert. Figure 5 As shown, the mold is in the fully opened state, waiting for the product to be ejected by the machine, thus ejecting the product contained within the male mold core.

[0045] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
