Description

Technical Field

[0001] This utility model belongs to the field of mold blank technology, and in particular relates to a mold blank with a rapid cooling structure. Background Technology

[0002] In injection molding, mold cooling efficiency directly affects production cycle, product quality, and energy consumption. Traditional mold base structures typically employ straight or simple loop cooling channels drilled inside the mold core or cavity for heat dissipation. However, such cooling layouts often suffer from uneven cooling, long heat conduction paths, and difficulty in eliminating localized hot spots. This is especially problematic in the molding of complex plastic products or products with significant wall thickness variations, easily leading to defects such as warping, shrinkage cavities, and internal stress concentration, severely impacting yield and accuracy. Furthermore, existing mold bases often lack dedicated channels for temperature monitoring and control circuitry, limiting sensor installation locations and resulting in messy wiring. This not only affects mold assembly compactness but also hinders accurate feedback and dynamic control of temperatures in critical areas. Simultaneously, traditional molds also have shortcomings in mold closing guidance, demolding mechanism layout, and modular maintenance. For example, low guiding accuracy easily leads to wear, and external ejection systems occupy a large space and are inconvenient to disassemble and assemble, thus restricting the improvement of production efficiency and automation levels.

[0003] To address this issue, we provide a mold blank with a rapid cooling structure. Utility Model Content

[0004] The purpose of this utility model is to provide a mold blank with a rapid cooling structure.

[0022] The mold blank with rapid cooling structure provided in this embodiment achieves efficient temperature control of the mold during injection molding by optimizing the overall cooling system layout and functional integration, thereby improving production efficiency and product quality. The mold blank arranges cooling channels 7 evenly along the circumference of the mold base and vertically aligns the cooling channels 7 between adjacent upper and lower mold bases, forming a continuous cooling circuit. This allows the cooling medium to flow quickly and evenly through the entire periphery of the mold cavity, effectively removing heat and preventing defects such as product deformation and shrinkage caused by localized overheating or uneven cooling. Simultaneously, a gate mounting hole 11 is provided in the center of the panel 1, and a wiring groove 12 extends from this hole downwards to connect with the top of the upper mold base 2, providing a dedicated path for temperature sensors or cooling control circuits. This not only ensures the safety and neatness of the wiring but also facilitates real-time monitoring of the mold temperature and dynamic adjustment in conjunction with the cooling system, enhancing the intelligent control capability of the mold. In addition, guide pillars 9 are located at the corners of each mold base to ensure precise alignment and stable operation during mold closing; the lifting seat 6 is integrated inside the mold foot 5, and the ejector pins move upward from the bottom of the mold cavity to demold the product, resulting in a compact structure and reliable operation. The overall mold blank adopts a modular stacked design, with each component connected by fasteners and equipped with handles 8 mounting holes, which facilitates assembly and disassembly, as well as handling and maintenance, fully balancing functionality, practicality, and manufacturing convenience.

[0023] Specifically, the wiring groove 12 extends downward from the gate mounting hole 11 along the inner side of the panel 1 and passes through to the top of the upper mold base 2, and is used to arrange temperature sensors or cooling control lines. The outlet of the wiring groove 12 is adjacent to the cooling channel 7 in the upper mold base 2. The cooling channel 7 is evenly distributed along the circumference of the upper mold base 2, the middle mold base 3 and the lower mold base 4, and passes through the side wall of each mold base. The cooling channels 7 on adjacent mold bases are aligned in the vertical direction to form a continuous cooling circuit.

[0024] Furthermore, the upper mold base 2, the middle mold base 3, and the lower mold base 4 form a closed mold cavity. The mold foot 5 is provided with a lifting seat 6, and multiple ejector pins configured on the lifting seat 6 pass through the bottom of the closed mold cavity. The sides of the panel 1, the upper mold base 2, the middle mold base 3, the lower mold base 4, and the mold foot 5 are all provided with screw holes for mounting the handle 8, and the panel 1, the upper mold base 2, the middle mold base 3, the lower mold base 4, and the mold foot 5 are arranged sequentially from top to bottom. The lower side of the upper mold base 2 is fixed to the middle mold base 3 by fasteners, and a channel hole is provided at the center of the upper mold base 2.

[0025] The operation process of this embodiment is as follows: First, the panel 1, upper mold base 2, middle mold base 3, lower mold base 4, and mold feet 5 are assembled sequentially from top to bottom. Guide pillars 9 ensure precise alignment of each mold base during mold closing. Fasteners are used to firmly connect the upper mold base 2 and the middle mold base 3, forming a structurally stable mold blank. Then, an injection gate system is installed at the gate mounting hole 11 in the center of the panel 1. Temperature sensors or cooling control lines are routed downwards along the wiring groove 12 from the inside of the gate mounting hole 11 to a position communicating with the top of the upper mold base 2, bringing the sensing or control elements close to the cooling channel 7 outlet for real-time acquisition of mold temperature data and feedback to the external control system. Next, external cooling medium pipes are connected to the aligned and continuous cooling channel 7 inlets on the side walls of each mold base, allowing... The coolant can form a continuous circulation loop in the upper mold base 2, middle mold base 3 and lower mold base 4 through circumferentially evenly distributed channels, achieving efficient and uniform cooling of the surrounding area of ​​the closed mold cavity. During the injection molding process, molten plastic is injected into the closed mold cavity formed by the upper mold base 2, middle mold base 3 and lower mold base 4 through the gate. At the same time, the cooling system runs continuously, quickly removing heat from the mold and shortening the product solidification time. After the product cools and sets, the lifting seat 6 inside the mold foot 5 is activated, driving multiple ejector pins to move upward from the bottom of the mold cavity, smoothly ejecting the finished product to complete demolding. The entire process is convenient to operate and has high cooling efficiency. Moreover, due to the integrated wiring and modular structure design, it is easy to maintain, replace or upgrade related functional components, significantly improving the production adaptability and automation level of the mold.
