Description

Technical Field

[0001] This utility model relates to the field of injection mold technology, and in particular to a mold runner plate structure and injection mold for improving heat dissipation of hot nozzles. Background Technology

[0002] In injection molds, the nozzle and runner are key components of the mold system. The nozzle, as the main channel connecting the injection machine nozzle and the mold cavity, primarily functions to deliver molten plastic to the cavity at a constant temperature and pressure. The runner, as the basic support structure of the mold, not only plays a crucial role in distributing molten plastic to each cavity but also provides the nozzle with mounting position and a heat conduction path. Since the nozzle, as the channel for conveying molten plastic, operates at high temperatures for extended periods, it is susceptible to deformation and performance degradation due to overheating; therefore, ensuring effective heat dissipation is essential.

[0003] In view of the above, a mold flow channel plate structure for improving the heat dissipation of the hot nozzle is proposed, thereby further improving the heat dissipation effect of the hot nozzle. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide a mold runner plate structure and injection mold that improves heat dissipation of the hot nozzle.

The heat dissipation groove structure is located on the side of the runner plate on which the hot nozzles are provided. Each hot nozzle is located within the heat dissipation groove structure, and the heat dissipation groove structure extends to the edge of the runner plate.

[0007] In one embodiment, the heat dissipation groove structure includes a horizontal heat dissipation groove, a vertical heat dissipation groove, and a heat nozzle clearance position.

[0016] Compared with the prior art, the present invention has at least the following advantages:

[0017] This utility model's mold runner plate structure for improving heat dissipation of the hot nozzle notch creates a heat dissipation groove structure on the runner plate, with the hot nozzle positioned within the groove structure.

[0021] To facilitate understanding of this utility model, a more comprehensive description of this utility model will be given below with reference to the accompanying drawings.

[0022] Please see Figure 1 and Figure 2As shown, a mold runner plate 200 structure for improving heat dissipation of the hot nozzle 100 includes: a hot nozzle 100 and a runner plate 200. The hot nozzle 100 is installed on one side of the runner plate 200, and a heat dissipation groove structure 210 is provided on the runner plate 200. The heat dissipation groove structure 210 is located on the side of the runner plate 200 where the hot nozzle 100 is provided. Each hot nozzle 100 is located in the heat dissipation groove structure 210, and the heat dissipation groove structure 210 extends to the edge of the runner plate 200.

[0023] It should be noted that by creating a heat dissipation groove structure 210 on the runner plate 200 and extending the groove structure 210 to the edge of the runner plate 200, the heat dissipation groove structure 210 is connected to the outside of the runner plate 200, forming an open heat dissipation channel. This utilizes natural air convection for heat dissipation. Simultaneously, the hot nozzle 100 is located within the heat dissipation groove structure 210, which not only reduces the contact area between the hot nozzle 100 and the runner plate 200 but also facilitates the rapid dissipation of heat emitted by the hot nozzle 100 to the outside of the runner plate 200 through the heat dissipation groove structure 210. This improves the heat dissipation effect of the hot nozzle 100 and thus extends the service life of the mold. In this embodiment, a cooling water channel is provided on the runner plate 200 to accelerate the heat dissipation of the hot nozzle 100 through water cooling. Combined with the heat dissipation groove structure 210, this greatly enhances the heat dissipation effect of the hot nozzle 100; the cooling water channel is arranged around the hot nozzle 100.

[0024] Specifically, the heat dissipation groove structure 210 includes a horizontal heat dissipation groove 211, a vertical heat dissipation groove 212, and a heat nozzle clearance position 213. The horizontal heat dissipation grooves 211 and the vertical heat dissipation grooves 212 are arranged in a crisscross pattern, and the heat nozzle clearance position 213 is connected to the horizontal heat dissipation grooves 211 and / or the vertical heat dissipation grooves 212. That is, the grooves of the heat dissipation groove structure 210 are arranged in a grid pattern, and the heat nozzle clearance position 213 is connected to the grooves. The heat nozzle clearance position 213 may be directly connected to the horizontal heat dissipation grooves 211, or directly connected to the vertical heat dissipation grooves 212, or simultaneously directly connected to both horizontal and vertical heat dissipation grooves, so as to achieve multi-directional heat dissipation, increase the heat dissipation area, and thus enhance the heat dissipation effect and improve the heat dissipation efficiency. In this embodiment, multiple horizontal heat dissipation grooves 211 are provided, each horizontal heat dissipation groove 211 extends to the edge of the flow channel plate 200, and each horizontal heat dissipation groove 211 is arranged at the same interval, thereby further improving the heat dissipation effect.

[0025] Furthermore, the depth and width of the horizontal heat dissipation groove 211 can be selected to match the size of the mold. Preferably, the depth of the horizontal heat dissipation groove 211 is 2-10mm and the width of the horizontal heat dissipation groove 211 is 30-80mm to ensure sufficient heat dissipation area.

[0026] Furthermore, multiple longitudinal heat dissipation slots 212 are provided, each extending to the edge of the flow channel plate 200, and each longitudinal heat dissipation slot 212 is arranged at the same interval, thereby further improving the heat dissipation effect.

[0027] Furthermore, the depth and width of the longitudinal heat dissipation groove 212 can be selected to match the size of the mold. Preferably, the depth of the longitudinal heat dissipation groove 212 is 2-10mm, and the width of the longitudinal heat dissipation groove 212 is 30-80mm to ensure sufficient heat dissipation area. In this way, a three-dimensional heat dissipation path is formed by the longitudinal heat dissipation groove 212 and the transverse heat dissipation groove 211, and the parallel operation of multiple heat dissipation channels improves reliability.

[0028] Furthermore, the hot nozzle clearance position 213 includes a clearance groove and a hot nozzle clearance hole. The hot nozzle 100 is installed in the hot nozzle clearance hole, and the clearance groove surrounds the hot nozzle clearance hole. The hot nozzle clearance hole communicates with the horizontal heat dissipation groove 211 and / or the vertical heat dissipation groove 212. The hot nozzle 100 is installed through the hot nozzle clearance hole, and the clearance groove is provided around the hot nozzle clearance hole to reduce the contact area between the hot nozzle 100 and the flow channel plate 200. At the same time, the heat of the hot nozzle 100 is discharged from the horizontal heat dissipation groove 211 and / or the vertical heat dissipation groove 212 as much as possible through the clearance groove, which can also improve the heat dissipation effect to a certain extent.

[0029] In one embodiment, four hot nozzles 100 are provided, and four hot nozzle clearance positions 213 are provided. The four hot nozzles 100 are matched with a four-cavity mold layout, and each hot nozzle 100 is matched with a hot nozzle clearance position 213 to ensure the heat dissipation effect of the hot nozzles 100.

[0030] In one embodiment, an avoidance groove 220 is provided on the side away from the heat dissipation groove structure 210. The avoidance groove 220 is used to install a flow divider plate. The flow divider plate is equipped with a heating system and other structures such as a main flow channel and a flow divider channel.

[0031] In one embodiment, the flow channel plate is further provided with multiple heat dissipation channels 230, which are connected to the avoidance groove to facilitate rapid heat dissipation of the flow distribution plate. At the same time, the cooling water channels are arranged around the flow distribution plate.
