[0002] The story machine is a digital early childhood education product that utilizes microprocessor-controlled voice circuitry and advanced electronic digital-analog microcontroller technology. A mold is a tool used to manufacture a product, and an electronic product casing mold is specifically designed for manufacturing the casing of electronic products. The story machine uses advanced electronic digital-analog microcontroller technology to synthesize the AiBeiDu chip, and its circuitry includes operation buttons and a microprocessor-controlled voice circuit, demonstrating mastery of core technologies.

[0003] An existing story machine shell mold structure can easily lead to cracks inside the mold after multiple molds are installed, thus affecting the mold's processing efficiency. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model provides a story machine shell mold structure.

[0005] This utility model is achieved by the following technical solution: a story machine shell mold structure, including a top positioning component, a buffer spring fixedly connected to the top of the top positioning component, a buffer support fixedly connected to the top of the top positioning component, a fixed column fixedly connected to the top of the top positioning component, and a positioning pin fixedly connected to the top of the top positioning component.

[0006] The top of the fixed column is inserted with a first outer mold, the top of the first outer mold is fixedly connected with a positioning support, the top of the first outer mold is inserted with an inner mold, the top of the first outer mold is snapped with a limiting block, the top of the positioning support is inserted with a second outer mold, the top of the second outer mold is inserted with a limiting top plate, the inside of the limiting top plate is fixedly connected with a fixing ring, the inside of the limiting top plate is inserted with an injection tube, the inside of the injection tube is slidably connected with a sealing ejector pin, the inside of the limiting top plate is inserted with an inner mold, and the inside of the second outer mold is fixedly connected with a cooling pipe.

[0007] As a further improvement to the above scheme, the number of the buffer springs and buffer supports is set to four, and each pair forms a group, with the four buffer springs and buffer supports symmetrically distributed around the top positioning component.

[0008] Through the above technical solution, four buffer springs and buffer pillars are symmetrically distributed around the top positioning component to form an elastic support system. This system absorbs the impact force during mold closing, suppresses the transmission of vibration to the mold cavity, ensures the smoothness of the molding surface, and at the same time compensates for the thermal expansion and contraction deviation caused by temperature changes through elasticity, thus maintaining the mold closing accuracy.

[0009] As a further improvement to the above solution, the top of the top positioning component contacts the bottom surface of the first outer mold, and the positioning pin is inserted into the interior of the first outer mold.

[0010] Through the above technical solution, the positioning pin is inserted into the first outer mold, and with the guiding effect of the fixed column, the upper and lower molds can be quickly aligned and locked, avoiding flash defects caused by misalignment. It is especially suitable for the high-precision molding requirements of complex curved shells.

[0011] As a further improvement to the above solution, the number of fixed columns and positioning supports is set to several, and the several fixed columns and positioning supports are symmetrically distributed around the top positioning component.

[0012] As a further improvement to the above solution, the cooling pipe is fixedly connected inside the inner mold and inside the first outer mold, and the top of the first outer mold is in contact with the bottom surface of the second outer mold.

[0013] As a further improvement to the above solution, the sealing ejector pin is located inside the second outer mold, the sealing ejector pin is located inside the limiting top plate, and the top of the injection tube is in contact with the bottom surface of the fixing ring.

[0014] The above technical solution allows for a sliding connection between the sealing pin and the injection tube, facilitating the disassembly and cleaning of residual plastic, preventing blockages from affecting the quality of subsequent injection molding, and reducing downtime for maintenance.

[0015] As a further improvement to the above solution, the second inner mold is inserted into the top of the first inner mold, the limiting block is inserted into the bottom of the second outer mold, and the second inner mold is located at the bottom of the limiting top plate.

[0016] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0017] This invention uses a fixed ring inside a limiting top plate to contact the top of the injection tube, dispersing the impact of injection pressure on the mold and preventing cracking caused by local stress concentration. It also acts as a safety barrier to block the risk of high-temperature plastic splashing. By setting a sealing ejector pin that slides inside the injection tube and works in conjunction with the fixed ring to limit the opening and closing of the injection port, the invention avoids overflow and waste. During the injection completion stage, the ejector pin seals the flow channel to prevent backflow and improve the yield rate.

[0018] This utility model supports the molding of multi-level complex structures by setting an inner mold two to be inserted into the top of an inner mold one, adapting to the irregular contour requirements of the story machine shell. The limiting support block and the limiting top plate correspond to each other to limit the relative displacement of the mold and ensure uniform interlayer fit gap. By setting a cooling pipe and a buffer support column to work together, the former controls the mold temperature and the latter maintains the structural rigidity, together resisting thermal fatigue under long-term high-temperature operation and extending the mold life.
