Description

Technical Field

[0001] This utility model relates to the field of plastic mold design technology, specifically a mold for a car center console decorative frame. Background Technology

[0002] In recent years, with the continuous development of automotive technology, most cars are equipped with a central control screen. In addition to traditional video playback functions, the central control screen can also display maps, reversing cameras, and other information. The central control trim frame is an important component of the central control screen, and it needs to be injection molded using plastic molds during production.

[0003] To save on plastic material consumption and speed up injection molding, achieving short molding time and high production efficiency, hot nozzles are often used for injection molding of the plastic mold of the central control decorative frame. However, the existing hot nozzles will cause deformation of the mold's A plate and front mold core during the long heating process, affecting the product size. Prolonged production without cooling will cause the mold to be scrapped.

[0004] Currently, the existing technology involves installing a hot nozzle sleeve on the hot nozzle. However, the hot nozzle sleeve needs to meet certain requirements: firstly, it must protect the hot nozzle from damage; secondly, it must achieve the effect of cooling the hot nozzle after injection molding; and thirdly, it must be simple to process and easy to assemble. However, existing conventional hot nozzle sleeve designs cannot meet these three requirements, thus necessitating a new hot nozzle sleeve design to solve the current problems. Utility Model Content

[0027] The structure of the mold for the automotive center console decorative frame provided by this utility model is as follows: Figures 1 to 4 As shown, the system includes a front half-module 1 and a rear half-module 5. The front half-module 1 includes a hot runner plate 3 and an A plate 4. The top of the A plate 4 is equipped with a hot runner plate 3 with inlet and outlet water channels, and the front mold core 41 is fixed inside the A plate 4. The front half-module 1 also includes a panel 2 with three hot nozzles.

The rear mold core 54 cooperates with the front mold core 41 to realize the injection molding operation.

[0028] Furthermore, such as Figure 4 , Figure 5 as well as Figure 6As shown, three sets of hot nozzle assemblies 6 are connected to the surface of the hot runner plate 3, and the bottom end of the hot nozzle assembly 6 passes through the A plate 4 and the front mold core 41 in sequence. The hot nozzle assembly 6 includes a mold hot nozzle 61, a hot nozzle sleeve 62 and a hot nozzle sleeve mother 63. The hot nozzle sleeve mother 63 is fixed to the surface of the hot runner plate 3 by bolts. The hot nozzle sleeve 62 is installed inside the hot nozzle sleeve mother 63. The upper and lower ends of the hot nozzle sleeve 62 and the hot nozzle sleeve mother 63 are sealed to each other by sealing rings 621. The mold hot nozzle 61 is provided inside the hot nozzle sleeve 62. The top end of the mold hot nozzle 61 passes through the hot runner plate 3 and communicates with the hot nozzle of the panel 2. The bottom end of the mold hot nozzle 61 communicates with the cavity formed after the front mold core 41 and the rear mold core 54 are closed.

[0029] During implementation, first, install some related components of the hot runner, including the hot nozzle 61, onto the hot runner plate 3. Then, install some components of the hot runner, including the cylinder, onto the panel 2. Guided by the four small guide pillars on the panel 2, the panel 2 and the hot runner plate 3 are assembled. Then, install the hot nozzle sleeve 62 onto the hot nozzle sleeve mother 63. Next, install the hot nozzle sleeve mother 63 onto the hot runner plate 3 with screws. After fixing, install the A plate 4 with the front mold core 41.

[0030] Furthermore, such as Figure 6 as well as Figure 8 As shown, the hot runner plate 3 has an inner anti-mistake platform 31 on its surface, and the hot nozzle sleeve 63 has an outer anti-mistake groove 631 on its outer surface. When the hot nozzle sleeve 63 is installed with the hot runner plate 3, the outer anti-mistake groove 631 and the inner anti-mistake platform 31 cooperate to prevent mistakes. The hot nozzle sleeve 62 has an outer anti-mistake platform 622 on its outer surface, and the hot nozzle sleeve 63 has an inner anti-mistake groove 632 on its inner wall. When the hot nozzle sleeve 62 is installed with the hot nozzle sleeve 63, the outer anti-mistake platform 622 and the inner anti-mistake groove 632 cooperate to prevent mistakes.

The top end of the water inlet groove 72 is connected to the water inlet tee hole 71, and the top end of the water outlet groove 74 is connected to the water outlet tee hole 75.

[0033] In practice, cooling water enters through the inlet channel of the hot runner plate 3 and flows into the inlet tee hole 71. It then flows through the inlet tee hole 71 to the inlet tank 72 and into the annular water delivery tank 73. Subsequently, it flows through the outlet tank 74 to the outlet tee hole 75 and finally flows out through the outlet channel of the hot runner plate 3, thereby realizing the cooling function of the hot nozzle assembly 6.

[0034] Working principle: In use, the cooling water inlet and outlet pipes are connected to the water inlet and outlet channels of the hot runner plate 3. The existing hot nozzle sleeve is designed as a mother-daughter sleeve, namely the hot nozzle sleeve daughter piece 62 and the hot nozzle sleeve mother piece 63. The hot nozzle sleeve daughter piece 62 is placed inside the hot nozzle sleeve mother piece 63. A water inlet tee hole 71 and a water outlet tee hole 75 are drilled on the hot nozzle sleeve mother piece 63. The gap at the middle connection between the hot nozzle sleeve mother piece 63 and the hot nozzle sleeve daughter piece 62 is completed by machining two straight groove water inlet grooves 72 and water outlet grooves 74 on a milling machine and a circular groove annular water conveying groove 73 on a lathe. This gap serves as a passage for cooling water. Standard sealing ring grooves matching the diameter of the hot nozzle sleeve daughter piece 62 are set on the top and bottom of the water passage of the hot nozzle sleeve daughter piece 62, and sealing rings 621 are installed to prevent water leakage.

[0035] During assembly, after installing the hot nozzle 61 onto the hot runner plate 3, the hot nozzle sleeve 62 is installed onto the hot nozzle sleeve female part 63. At this point, the inner anti-misalignment groove 632 and the outer anti-misalignment platform 622 cooperate to achieve misalignment prevention. Next, the hot nozzle sleeve female part 63 is installed onto the hot runner plate 3 with screws. During installation, the outer anti-misalignment groove 631 and the inner anti-misalignment platform 31 cooperate to achieve misalignment prevention. After fixing, the A plate 4 containing the front mold core 41 is installed. Then, the hot nozzle sleeve female part 63 and the hot runner plate 3 are fixed with screws. After fixing, the A plate 4 containing the front mold core 41 is installed. This ensures that the hot nozzle 61 is not damaged during assembly. After all mold components are assembled, the injection molding machine is installed, and all water circulation circuits are connected. After adjusting the injection molding machine parameters and producing qualified products, normal production can begin.
