[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0024] Currently, optocoupler products with different packaging forms usually use different mold boxes. The mold boxes lack interchangeability and commonality, and it is necessary to replace different special molds when performing different packaging forms, which increases the operation time and reduces production efficiency. Moreover, when the existing mold boxes are combined, there are gaps between the upper mold box and the lower mold box, and the sealing performance is poor. During the packaging process, external air, moisture, and pollutants are likely to enter the mold interior, resulting in damage to the internal components of the optocoupler product. The liquid packaging material may leak from the gaps, causing incomplete packaging and affecting product quality.

[0025] To solve the defects existing in the above mold box during the packaging process, please refer to Figures 1 - 6, a general packaging mold box for optocoupler products provided by the utility model. When packaging different series of optocoupler products, there is no need to replace the mold box, which saves operation time and enhances the sealing performance of the mold box. It can not only improve work efficiency but also ensure the quality of product packaging. The packaging mold box is based on the lower mold box 1 and the upper mold box 2. A barrel module 101 is arranged at the center position of the top of the lower mold box 1. A round hole for installing the barrel is opened on the barrel module 101. A first sealing frame 102 and a second sealing frame 103 are arranged inside both the lower mold box 1 and the upper mold box 2. The first sealing frame 102 and the second sealing frame 103 are respectively arranged on both sides of the barrel module 101. The first sealing frame 102 on the lower mold box 1 corresponds to the first sealing frame 102 on the upper mold box 2, and the second sealing frame 103 on the lower mold box 1 corresponds to the second sealing frame 103 on the upper mold box 2. The first sealing frame 102 and the second sealing frame 103 can respectively perform SOP packaging and DIP packaging on the optocoupler products, and both the first sealing frame 102 and the second sealing frame 103 are detachably arranged. The first sealing frames 102 and the second sealing frames 103 for DIP and SOP packaging can be replaced and used with each other and can be shared on the same lower mold box 1. A runner ejector rod 105 and two groups of cavity ejector rods 106 are installed inside both the lower mold box 1 and the upper mold box 2. The two groups of cavity ejector rods 106 respectively correspond to the first sealing frame 102 and the second sealing frame 103. The cavity ejector rod 106 is used to support and fix the first sealing frame 102 and the second sealing frame 103. The runner ejector rod 105 is arranged between the two groups of cavity ejector rods 106. A runner module is arranged inside both the lower mold box 1 and the upper mold box 2. The runner ejector rod 105 is used to support and fix the runner module. A lower frame ejector rod 104 is installed on one side inside the lower mold box 1. Mounting plates 107 for fixing the runner ejector rod 105 and the cavity ejector rods 106 are installed on both the lower mold box 1 and the upper mold box 2. A bottom plate 108 is arranged at the bottom of the mounting plate 107 on the lower mold box 1. The bottom plate 108 is used to support the lower mold box 1. During the production process, the lower mold box 1 and the upper mold box 2 can be used to package optocoupler products with DIP packaging and SOP packaging without replacing different lower mold boxes 1 and upper mold boxes 2, saving costs and time and improving production efficiency.

[0026] Since there is a gap between the lower mold box 1 and the upper mold box 2 when they are closed, during the packaging process, external air, moisture, and pollutants are likely to enter the lower mold box 1, resulting in damage to the internal components of the optocoupler product. The liquid packaging material may leak from the gap, causing incomplete packaging. To solve this technical problem, refer to Figures 2 - 6As shown in the figure, a sealing cavity 3 is formed on the lower mold box 1. The sealing cavity 3 is set as a circular groove. A sealing component 4 is installed at the bottom of the upper mold box 2. Among them, the sealing strip 41 is adapted to the sealing cavity 3. A plurality of pointed tooth grooves 5 are formed on both sides of the inner wall of the sealing cavity 3. The cross-section of the pointed tooth groove 5 is triangular. Filling teeth 42 adapted to the pointed tooth grooves 5 are fixedly connected to both the inner wall and the outer wall of the sealing strip 41. The sealing strip 41 and the filling teeth 42 are both made of rubber and have a certain elasticity. The sealing strip 41 is inserted into the sealing cavity 3. During the process of the sealing strip 41 going deep, the filling teeth 42 are deformed by the extrusion of the inner wall of the sealing cavity 3. When the installation of the sealing strip 41 is completed, the plurality of filling teeth 42 are respectively aligned with the plurality of pointed tooth grooves 5. The filling teeth 42 can enter the pointed tooth grooves 5 according to their own elasticity, fixing the upper mold box 2 on the lower mold box 1. External force is required to remove the upper mold box 2, preventing the upper mold box 2 from loosening, which can enhance the connection stability between the lower mold box 1 and the upper mold box 2. After the sealing strip 41 enters the sealing cavity 3, the inner joint seam between the lower mold box 1 and the upper mold box 2 can be blocked, enhancing the sealing performance of the connection between the lower mold box 1 and the upper mold box 2, preventing external pollutants from entering the lower mold box 1, and also avoiding the leakage of liquid packaging materials, ensuring product quality.

[0027] Since filling teeth 42 are provided on both sides of the sealing strip 41, in order to ensure that the sealing strip 41 and the filling teeth 42 can be smoothly inserted into the sealing cavity 3, the width of the sealing strip 41 is made smaller than the width of the sealing cavity 3. And a blocking strip 43 is fixedly connected to the top of the sealing strip 41. The width of the blocking strip 43 is adapted to the width of the sealing cavity 3. The blocking strip 43 can fill the sealing cavity 3, filling the gap between the sealing strip 41 and the sealing cavity 3, ensuring the sealing performance of the sealing strip 41. And a sealing cover 44 is fixedly connected to the top of the blocking strip 43. The sealing cover 44 is fixedly installed at the bottom of the upper mold box 2. The width of the sealing cover 44 is larger than the width of the sealing cavity 3. The sealing cover 44 can cover the sealing cavity 3 to block the sealing cavity 3, further ensuring the sealing effect of the sealing strip 41.

[0028] In order to seal the external joint seam between the lower mold box 1 and the upper mold box 2, an outer sealing plate 8 is fixedly sleeved outside the lower mold box 1. The height of the outer sealing plate 8 is greater than the height of the lower mold box 1. When the upper mold box 2 is installed on the lower mold box 1, the upper mold box 2 is located inside the outer sealing plate 8. The outer sealing plate 8 can seal the joint seam between the lower mold box 1 and the outside of the upper mold box 2, and cooperate with the sealing component 4 to achieve double sealing at the connection between the lower mold box 1 and the upper mold box 2.

[0029] In order to facilitate the combination of the lower mold box 1 and the upper mold box 2, positioning holes 6 are formed at the four corners of the lower mold box 1. Positioning rods 7 are fixedly connected to the four corners of the upper mold box 2. The positioning rods 7 are adapted to the positioning holes 6. The setting of the positioning rods 7 and the positioning holes 6 can play a guiding role in the installation of the upper mold box 2.
