Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically relating to an arc-shaped ejection mold structure. Background Technology

[0002] In the injection molding production process, when dealing with products with curved structures, the traditional left-right ejection method is often ineffective in meeting actual production needs. Due to these limitations, these traditional methods frequently lead to a series of problems. For example, the product may be damaged during demolding because traditional ejection methods cannot adapt well to the characteristics of curved structures, failing to provide the appropriate demolding force and angle. Furthermore, demolding difficulty is also a common problem; the inability to precisely match the shape characteristics of curved products makes demolding operations complex and difficult. Moreover, traditional ejection methods significantly reduce production efficiency, as the complex and inefficient demolding process severely impacts the overall production schedule and output. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides an arc-shaped ejector structure to solve the problem of difficult demolding of existing arc-shaped injection molded products. This arc-shaped ejector structure can improve demolding efficiency and the integrity of injection molded products, and avoid damage to injection molded products during the demolding process.

[0004] This utility model provides an arc-shaped sliding ejection structure, including a mold, a pushing mechanism, an injection tube, a linear sliding slide, a connecting rod, an arc-shaped sliding slide, and an injection needle. The mold is provided with an arc-shaped guide groove. The arc-shaped sliding slide is slidably disposed in the arc-shaped guide groove between a first position and a second position. An injection cavity is provided in the arc-shaped sliding slide. The injection cavity is arc-shaped. The injection tube is fixed to the mold. The linear sliding slide is linearly slidably disposed on the mold. The pushing mechanism is connected to the linear sliding slide. The two ends of the connecting rod are rotatably connected to the linear sliding slide and the arc-shaped sliding slide, respectively. The linear sliding slide drives the arc-shaped sliding slide to slide. The injection needle is disposed on the linear sliding slide. When the arc-shaped sliding slide is in the first position, the injection needle is connected to the injection tube, and the injection cavity is connected to the injection tube. When the arc-shaped sliding slide slides from the first position to the second position, both the arc-shaped sliding slide and the injection needle are separated from the injection tube.

[0005] Furthermore, the actuating mechanism is a hydraulic cylinder.

[0006] Furthermore, the injection-molded tube has an arc-shaped structure.

[0007] This arc-shaped sliding mold release structure has the following advantages:

[0008] Improved production efficiency: This arc-shaped ejection structure enables automated demolding of arc-shaped products. Compared with traditional demolding methods, it reduces operation steps and time, and greatly improves production efficiency.

[0009] Ensuring product quality: The precise sliding of the arc-shaped travel position in the arc-shaped guide groove, as well as the precise cooperation between the injection needle, injection cavity, and injection tube, ensures the stability and consistency of the injection molding process, thereby effectively guaranteeing the quality of the arc-shaped products.

[0010] Reduced product damage rate: During the demolding process, the arc-shaped travel path slides along the preset arc trajectory, which can better adapt to the shape of the arc-shaped product, avoid product damage caused by improper demolding method, and reduce the defect rate.

[0011] Enhancing mold versatility: The design of using a push mechanism to drive a linear traveling slide, and then using a connecting rod to link an arc-shaped traveling slide, allows this structure to be applied to the production of arc-shaped products of different sizes and specifications, thus enhancing the versatility of the mold.
