Description

Technical Field

[0001] This utility model relates to the field of mold technology, and in particular to a hot runner and mold. Background Technology

[0002] In existing technology, for injection molds of preforms with handles, the preform cavity and the handle cavity are interconnected. Typically, a nozzle located at the bottom of the preform is placed in the hot runner to achieve integral injection molding of the preform and handle. During our use, we found that because the top of the handle cavity is connected to the top of the preform cavity, the handle is the slowest point to fill with glue during injection, affecting injection time and slowing down the production cycle. Secondly, the mold cannot be opened until the handle has fully cooled and solidified, which affects the adjustment of the preform's heat, thus impacting blow molding. Summary of the Invention

[0003] According to an embodiment of the present invention, a hot runner is provided, comprising a hot runner body and a sprue, wherein the sprue is disposed on the hot runner body and connected to an external injection molding machine nozzle, and further comprising:

[0004] The preform nozzle is connected to the injection port and the bottom of the external preform cavity, and delivers the injection material into the preform cavity.

[0005] The handle nozzle is connected to the injection port and the bottom of the external handle cavity, and delivers the injection material into the handle cavity.

[0006] Furthermore, heaters are fitted over both the preform nozzle and the handle nozzle.

[0007] Furthermore, the height of the handle nozzle is higher than the height of the preform nozzle.

[0008] This utility model also discloses a mold, which includes a mold body. The mold body has a preform cavity and a handle cavity. The top end of the handle cavity is connected to the preform cavity, and includes a hot runner as described above.

[0009] This utility model further discloses a handle preform, which is injection molded from the above-mentioned mold.

[0010] Furthermore, it includes: a preform and a handle, with the upper end of the handle connected to the preform and a gap between the lower end of the handle and the preform.

[0011] According to the hot runner, mold, and handle preform of this utility model embodiment, by adding a handle nozzle, the handle can be injection molded separately without being affected by the preform injection, which can shorten the injection time and ensure the heat of the preform for blow molding a qualified handle bottle.

[0012] It should be understood that both the foregoing general description and the following detailed description are exemplary and intended to provide further illustration of the claimed technology. Attached Figure Description

[0014] Reference numerals: 1. Preform; 2. Handle; 3. Hot runner; 4. Inlet; 5. Preform nozzle; 6. Handle nozzle; 7. Heater. Detailed Implementation

[0015] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings, further illustrating the present invention.

[0016] First, combine Figure 1 The description of the hot runner, mold, and handle 2 preforms 1 according to the embodiments of the present utility model has a wide range of applications.

[0017] like Figure 1 As shown, the hot runner of this utility model embodiment includes a hot runner body 3 and a glue inlet 4. The glue inlet 4 is disposed on the hot runner body 3 and connected to the external injection molding machine nozzle. It also includes a preform nozzle 5 and a handle nozzle 6.

[0018] Specifically, such as Figure 1 As shown, in this embodiment, the preform nozzle 5 is connected to the inlet 4 and the bottom of the preform 1 cavity, and the preform nozzle 5 delivers injection material into the preform 1 cavity; the handle nozzle 6 is connected to the inlet 4 and the bottom of the handle 2 cavity, and the handle nozzle 6 delivers injection material into the handle 2 cavity; the injection material is plastic. By adding a handle nozzle 6, the handle 2 can be injection molded independently, unaffected by the preform 1 injection, which shortens the injection time and ensures the heat of the preform 1 for blow molding of qualified handle 2 bottles.

[0019] Furthermore, such as Figure 1 As shown, in this embodiment, both the preform nozzle 5 and the handle nozzle 6 are fitted with heaters 7 to ensure that the nozzles maintain a predetermined temperature.

[0020] Furthermore, such as Figure 1 As shown, in this embodiment, since the bottom of the preform 1 and the bottom of the handle 2 are at different heights, the height of the handle nozzle 6 is higher than the height of the preform nozzle 5, so that the handle nozzle 6 can communicate with the bottom of the cavity of the handle 2.

[0021] like Figure 1As shown, in this embodiment, the present invention also discloses a mold, which includes a mold body. The mold body is provided with a preform cavity 1 and a handle cavity 2. The top end of the handle cavity 2 is connected to the preform cavity 1. It also includes a hot runner as described above. The bottom of the handle cavity 2 and the bottom of the preform cavity 1 are provided with openings to connect the handle nozzle 6 and the preform nozzle 5, respectively.

[0022] like Figure 1 As shown in this embodiment, the present invention further discloses a handle preform, which is injection molded by the above-mentioned mold.

[0023] Furthermore, such as Figure 1 As shown, in this embodiment, it includes: bottle preform 1 and handle 2, the upper end of handle 2 is connected to bottle preform 1, and there is a gap between the lower end of handle 2 and bottle preform 1.

[0024] Above, refer to Figure 1 The present invention describes a hot runner, mold, and handle preform according to an embodiment of the present invention. By adding a handle nozzle, the handle can be injection molded separately without being affected by the preform injection, which can shorten the injection time and ensure the heat of the preform for blow molding a qualified handle bottle.
