Description

Technical Field

[0001] This application relates to the technical field of molds, and in particular to a production mold for silicone products. Background Art

[0002] A mold is a variety of dies and tools used in industrial production to obtain the required products by injection molding, blow molding, extrusion, die casting, forging, smelting, stamping, etc. Molds are also widely used in the production of silicone products.

[0003] Among them, silicone nipples are usually produced by molds. Existing nipple molds usually tightly fit the upper mold and the lower mold, then use bolts to tighten and fix them, and finally inject silicone. However, during the production process, the bolts on the mold need to be disassembled and screwed many times, which not only increases the workload of the staff, but also increases the time required for mold injection and demolding, making it inconvenient to improve the efficiency of mold injection and demolding, and thus needs to be improved. Utility Model Content

[0005] A production mold for silicone products provided by this application adopts the following technical solutions:

[0006] A production mold for silicone products includes a lower mold and an upper mold. Installation frames are fixed on both sides of the lower mold, and the two installation frames are symmetrically distributed. A rotating plate is rotatably installed on the top of the installation frame through a rotating shaft; two pairs of embedding grooves are opened on the top of the upper mold, and each pair of embedding grooves has two; a clamping mechanism is also included. Both clamping mechanisms include toggle clamps fixed on the rotating plate, and the clamping mechanism is used to connect and fix the lower mold and the upper mold.

[0007] Preferably, an extrusion plate is fixed at the chuck end of the toggle clamp, and embedding heads are fixed at both bottom ends of the extrusion plate. The embedding heads are adapted to the embedding grooves.

[0008] Preferably, a pair of reinforcing plates are fixed on the installation frame, and waist-shaped holes are opened on the reinforcing plates.

[0009] Preferably, a pair of positioning columns are fixed on the top of the lower mold, and are located at the bottom of the upper mold. A pair of positioning grooves are respectively opened corresponding to the positioning columns. The positioning columns are adapted to the positioning grooves, and chamfers are provided at the openings of the positioning grooves.

[0010] Preferably, a sealing edge groove is opened on the top side of the lower mold, and a sealing edge frame is fixed on the bottom side of the upper mold. The sealing edge frame is adapted to the sealing edge groove.

[0011] Preferably, anti-slip strips are fixedly adhered to the bottom of the lower mold, and the anti-slip strips are made of rubber material.

[0012] In summary, the present application includes the following beneficial technical effects:

[0013] 1. By setting the clamping mechanism, operating the toggle clamp in the clamping mechanism can lower the extrusion plate, so that the embedding heads are respectively embedded into the embedding grooves on the upper mold, thereby tightly pressing the upper mold on the lower mold, realizing the tight connection and stable connection of the two molds, eliminating the need for traditional multiple screw tightening of bolts. The staff only needs to press the operating rod on the toggle clamp to complete the installation, saving the time used for injection mold installation and demolding disassembly, improving work efficiency, with simple operation and high practicability.

[0014] 2. By setting the edge-sealing groove and the edge-sealing frame, the outflow of molten silica gel can be avoided, further improving the sealing performance between the two molds. By setting the positioning posts and the positioning grooves, the lower mold and the upper mold can be assembled and connected faster, improving practicability. Description of the Drawings

[0020] The following further elaborates on the present application in conjunction with the attached Figures 1-4 for further detailed description of the present application.

[0021] The embodiment of the present application discloses a silicone product production mold. Refer to Figures 1 to 4, A production mold for silicone products, including a lower mold 1 and an upper mold 2. The upper mold 2 has an injection hole. On both sides of the lower mold 1, mounting brackets 3 are fixed. The two mounting brackets 3 are symmetrically distributed. At the top of the mounting bracket 3, a rotating plate 5 is rotatably mounted through a rotating shaft. There is a sliding damping between the rotating plate 5 and the rotating shaft, which has the function of keeping the rotating plate 5 stable without external force; on the top of the upper mold 2, two pairs of embedding grooves 7 are opened, and each pair of embedding grooves 7 has two; it also includes a clamping mechanism. Both clamping mechanisms include toggle clamps 6 fixed on the rotating plate 5. The clamping mechanism is used to connect and fix the lower mold 1 and the upper mold 2. At the clamping head end of the toggle clamp 6, a pressing plate 8 is fixed. At both ends of the bottom of the pressing plate 8, embedding heads 9 are fixed, and the embedding heads 9 are adapted to the embedding grooves 7.

[0022] By adopting the above technical solution, during use, align the positioning posts 11 with the positioning grooves 13, and rotate the toggle clamps 6 180° in sequence, which can avoid the toggle clamps 6 from interfering with the upper mold 2 covering the lower mold 1. After the upper mold 2 covers the lower mold 1, turn back the toggle clamps 6 respectively, then align the embedding heads 9 and the embedding grooves 7, and press down the operating rod on the toggle clamp 6, then the pressing plate 8 can be moved downward and pressed on the upper mold 2. After operating the two groups of toggle clamps 6, the installation is completed. The operation is convenient, fast, and practical.

[0023] Refer to Figure 1 , A pair of reinforcing plates 4 are fixed on the mounting bracket 3. Waist-shaped holes are opened on the reinforcing plates 4. This setting is convenient for improving the self-strength of the mounting bracket 3. The waist-shaped holes are convenient for reducing the overall weight of the mounting bracket 3, making the lower mold 1 easy to carry and take.

[0024] Refer to Figure 2 and Figure 4 , A pair of positioning posts 11 are fixed on the top of the lower mold 1. At the bottom of the upper mold 2, and a pair of positioning grooves 13 are respectively opened corresponding to the positioning posts 11. The positioning posts 11 are adapted to the positioning grooves 13. A chamfer 15 is provided at the notch of the positioning groove 13. This setting is convenient for the quick positioning of the lower mold 1 and the upper mold 2, facilitating quick splicing and installation, improving the installation efficiency, and being convenient for use.

[0025] Refer to Figure 2 and Figure 4 , At the side of the top of the lower mold 1, a sealing edge groove 10 is opened. At the side of the bottom of the upper mold 2, a sealing edge frame 14 is fixed. The sealing edge frame 14 is adapted to the sealing edge groove 10. This setting is convenient for improving the sealing performance between the lower mold 1 and the upper mold 2, thus avoiding the molten silicone flowing out during injection molding.

[0026] Refer to Figure 3, an anti-slip strip 12 is fixedly adhered to the bottom of the lower mold 1. The anti-slip strip 12 is made of rubber. The anti-slip strip 12 can improve the stability of the placement of the lower mold 1 and prevent the lower mold 1 from shifting when the toggle clamp 6 is pressed down.

[0027] The implementation principle of a silicone product production mold according to an embodiment of the present application is as follows: During use, align the positioning post 11 with the positioning groove 13, and sequentially rotate the toggle clamp 6 by 180°. This can prevent the toggle clamp 6 from interfering with the upper mold 2 covering the lower mold 1. After the upper mold 2 covers the lower mold 1, rotate the toggle clamp 6 back respectively, then align the embedding head 9 and the embedding groove 7, and press down the operating rod on the toggle clamp 6, then the pressing plate 8 can be moved downward and pressed on the upper mold 2. After operating the two toggle clamps 6, the installation is completed. The operation is convenient, fast, and practical. After the injection molding is completed, lift the operating rods on the toggle clamps 6 respectively to release the fixation, and then rotate the toggle clamp 6 by 180°, then the upper mold 2 can be removed, and thus demolding can be achieved.
