Description

Technical Field

[0001] This utility model relates to the field of mold frame technology, and more specifically, to an intelligent mold frame. Background Technology

[0002] A mold base is the basic framework structure used in industrial molding processes to support, position, and fix the mold cavity and related components; it is equivalent to the "skeleton" of the mold. It typically consists of components such as templates, support columns, and guide mechanisms, and is widely used in molding processes such as injection molding, die casting, stamping, and 3D printing. The core function of the mold base is to provide a stable mounting reference for the mold, ensuring the relative positional accuracy of the mold components during the molding process, while also withstanding physical loads such as pressure during molding.

[0003] Existing mold bases, when actually installed and used, need to support the mold and inject material into the mold cavity through mold closing to complete the injection molding of the workpiece. However, in actual working conditions, traditional mold bases often lack intelligent temperature regulation structures. When the material temperature drops, the melt fluidity will decrease significantly. Especially in injection molding of complex cavities or thin-walled structures, problems such as insufficient mold filling and obvious weld lines are likely to occur, resulting in material shortage on the surface of the product and internal stress concentration, which directly affects the dimensional accuracy and mechanical properties of the injection molded product.

[0004] After injection molding, the workpiece needs to be cooled stably to improve molding efficiency, but the residual heat in the traditional mold heating chamber is difficult to dissipate quickly. If an exhaust port is directly opened in the heating chamber, although heat dissipation can be accelerated, heat loss will occur in the initial heating stage, resulting in slow mold heating. This not only prolongs the production preparation time, but also increases the energy consumption required for the material to reach the ideal flow state, creating a contradictory dilemma between "cooling efficiency and heating energy consumption", making it difficult to achieve an optimal balance between production cycle and energy consumption.

[0005] In view of this, we propose an intelligent template. Utility Model Content

After injection molding of the workpiece, multiple electric push rods can be activated again to move the baffle plate upward, thus exposing multiple exhaust vents. Compressed gas is then injected into the three-way solenoid valve, which in turn enters multiple internal cooling sources. The cooled gas can then be delivered to cavities one and two through multiple cooling gas delivery pipes, allowing the mold to cool more quickly, thereby improving its cooling efficiency without affecting its initial heating efficiency.
