Description

Technical Field

[0001] This utility model relates to the technical field of plastic toy assembly equipment, and in particular to an internal dispensing device for plastic toy molds. Background Technology

[0002] Plastic toys refer to children's or adults' entertainment products made from synthetic resins such as PVC, ABS, and PP as the main raw materials and processed through injection molding, blow molding, and other processes. They are characterized by being lightweight, durable, low-cost, and highly malleable, and encompass various forms such as building blocks, dolls, and models.

[0003] Plastic toy molds are precision tools specifically designed for the mass production of plastic toys. Typically made of steel or aluminum alloy, they are sculpted using CNC machining or EDM processes to create the toy's three-dimensional cavity structure. Their core function is to inject molten plastic into the mold cavity, allowing it to cool and solidify, ensuring precise dimensions and a smooth surface. Mold design must consider details such as draft angles, parting lines, and ejector pin layouts, and be compatible with the clamping force and injection volume of the injection molding machine, ultimately achieving high-efficiency, low-cost mass production of toys.

[0004] Based on this, Chinese patent document CN112895236B discloses a mold for processing plastic toys, which includes a base, a linear slide rail, a sliding plate, a first cylinder, a connecting rod, a nozzle, a support plate, a fan, a locking block, a connecting column, a mold body, a buffer pad, a moving plate, an L-shaped rod, a partition plate, a lead screw, a rotating block, a fixing plate, a second cylinder, a vertical plate, and a limiting block. This technical solution uses the installed locking block and limiting block to limit and fix the partition plate, which facilitates the fixing of the mold body, thereby facilitating the assembly and disassembly of the mold body and the replacement of mold bodies of different shapes for production, thus expanding the scope of application of this invention. By using the installed fan, linear slide rail, sliding plate, and nozzle, the first cylinder drives the connecting rod and sliding plate to reciprocate, and then the nozzle is used to cool different positions of the mold body, improving cooling efficiency and thus increasing productivity.

[0005] However, existing plastic toy mold manufacturing processes suffer from low dispensing efficiency. Specifically, in plastic toy mold manufacturing, the dispensing process is mainly used to achieve precise color zoning and three-dimensional decorative effects. The process typically involves: mold preparation, cleaning the silicone / metal mold and applying a release agent; mixing the epoxy resin and curing agent in proportion (color paste can be added); injection; the operator manually injects the glue into the mold cavity (complex structures require multiple fillings); defoaming; vacuum defoaming or static setting to eliminate air bubbles; curing; hardening at room temperature or with heat; demolding; removing the mold and trimming rough edges; post-processing; UV coating or polishing to enhance the surface effect. The core of this dispensing process is to achieve transparent decoration, multi-color parts, or a crystal-like texture in toys through precise filling and curing of liquid glue. However, in existing plastic mold dispensing processes, workers typically operate by hand with a dispensing cylinder, and the amount of glue dispensed each time depends on the worker's experience to control, resulting in low efficiency in the plastic toy mold dispensing process.
