[0025] The embodiment of the present application provides a spring-open optical fiber mold, which solves the problem that it is inconvenient to demould the handle, and the long-term use of the spring will cause the spring elasticity to decrease. In actual use, the problem of difficult demoulding of the handle is solved, making demoulding smoother; at the same time, the elasticity of the spring can be adjusted to maintain a stable demoulding effect, extend the effective cycle of the mold, and improve adaptability and production efficiency.

[0026] In order to better understand the above technical solution, the above technical solution will be described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0027] Reference Figure 1-5 , a pop-up optical fiber mold, comprising: a fixed mold base plate 1, used for the fixed mold part of the mold to be firmly installed on the fixed mold plate of the injection molding machine to ensure the stability of the mold during the injection molding process; a fixed mold plate 2; located directly below the fixed mold base plate 1, and the fixed mold plate 2 is slidably connected to the fixed mold base plate 1, and the fixed mold plate 2 is used to fix the upper mold core; a plurality of mounting grooves 7 are provided, and are evenly provided on the fixed mold plate 2 and the fixed mold base plate 1, and the fixed mold plate 2 corresponds to the mounting grooves 7 on the fixed mold base plate 1; a plurality of springs 8 are provided, and the springs 8 are located in the mounting grooves 7, and are used to push the fixed mold plate 2 to move; a plurality of limit rods 11 are provided, and one end of the limit rod 11 passes through the fixed mold plate 2 and is threadedly connected to the fixed mold base plate 1, the limit rod 11 is used to support the fixed mold plate 2, and the limit rod 11 is used to limit the sliding stroke of the fixed mold plate 2.

[0028] Through the cooperation between the above structures, when the mold is opened, the fixed mold plate 2 is first pushed to move by the spring 8 so that the material handle on the upper mold core is separated from the injection port.

[0029] The movable mold plate 3 is located directly below the fixed mold plate 2, and the movable mold plate 3 is used to fix the lower core.

[0030] The lower core can be fixed by the fixed template 2.

[0031] The support plate 4 is located directly below the movable platen 3 and is firmly connected to the movable platen 3. The support plate 4 is used to bear part of the injection pressure and the weight of the mold itself and the product.

[0032] The support plate 4 can play an important role in supporting and sharing pressure.

[0033] There are two cushion blocks 5, and the cushion blocks 5 are firmly connected to the bottom of the support plate 4. The cushion blocks 5 are used to share and bear part of the pressure from the mold opening and closing and the injection molding process.

[0034] A space is created between the movable die base plate 6 and the support plate 4 by the cushion block 5 so that structures such as the push plate can be moved.

[0035] The movable mold base plate 6 is firmly connected to the bottom of the cushion block 5, and the movable mold base plate 6 is used to firmly install the movable mold part of the mold on the movable mold plate of the injection molding machine.

[0036] The movable mold part of the mold can be connected and installed with the movable mold plate of the injection molding machine through the movable mold base plate 6.

[0037] The elastic force adjusting screw 9 is located in the mounting groove 7, and the vertical center line of the elastic force adjusting screw 9 coincides with the vertical center line of the spring 8; the limiting member 901 is located in the mounting groove 7, and the limiting member 901 is firmly connected to the elastic force adjusting screw 9, and the limiting member 901 is directly below the spring 8; the adjusting plate 10 is located in the mounting groove 7, and the adjusting plate 10 is threadedly connected to the elastic force adjusting screw 9, and the adjusting plate 10 is between the limiting member 901 and the spring 8, and the adjusting plate 10 is used to squeeze the spring 8.

[0044] The diameter of the adjustment plate 10 is larger than the inner diameter of the spring 8 .

[0045] The diameter of the adjustment plate 10 should be appropriately larger than the inner diameter of the spring 8 to achieve effective control and adjustment of the spring 8 .

[0046] During use, when using the mold for injection molding, first fix the fixed mold base plate 1 on the fixed template of the injection molding machine, and fix the movable mold base plate 6 on the movable template of the injection molding machine; then inject the molten plastic into the mold, and after cooling and solidification, the mold is opened, and the spring 8 pushes the fixed template 2 to move, thereby driving the material handle on the upper core to separate from the injection port; in this process, the limit rod 11 plays the role of supporting the fixed template 2 and limiting the sliding stroke of the fixed template 2, ensuring the normal operation of the mold; after long-term use, if the elastic force of the spring 8 decreases, the position of the adjustment plate 10 can be adjusted by rotating the elastic force adjustment screw 9, thereby squeezing the spring 8 and increasing the elastic force of the spring 8; the limit member 901 and the limit block 1001 play the role of limiting the movement of the adjustment plate 10, ensuring the accuracy and stability of the adjustment.

[0047] The push rod, push rod fixing plate, guide column, guide sleeve and other structures required for the above-mentioned mold are all existing technologies and are non-essential technical features in this application, so they are not described or drawn in detail in the documents and drawings of this application.

[0048] In summary, compared with the prior art, the present invention has the following beneficial effects: it solves the problem that the injection molded plastic handle is difficult to detach from the injection port, thereby improving production efficiency and product quality; it adopts a spring-open design, and utilizes the elastic force of the spring to achieve automatic demolding, thereby simplifying the demolding process and reducing the difficulty of manual operation; at the same time, an elastic force adjustment device is provided, which can adjust the elastic force of the spring in real time as needed to ensure the stability and consistency of the demolding effect; it extends the service life of the mold, and reduces the mold maintenance and replacement costs caused by the decrease in spring elastic force; and it improves the adaptability of the mold, which can meet the production needs of optical fiber products of different specifications and shapes.
