Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.
[0025] Specific implementation examples are given below.
[0026] Please see Figure 1 - Figure 4This utility model provides a connector injection mold that is easy to demold, including a lower mold 1; the top of the lower mold 1 has multiple guide holes 11; multiple positioning pins 12 are fixedly connected to the top of the lower mold 1; a mold core 13 is fixedly connected to the top of the lower mold 1; multiple guide rods 14 are slidably connected to the side walls of the multiple guide holes 11; an upper mold 16 is fixedly connected to the top of the multiple guide rods 14; the bottom of the upper mold 16 has multiple positioning holes 15; the multiple positioning holes 15 correspond to the positioning pins 12; the bottom of the upper mold 16 has a cavity 17; the top of the cavity 17 is equipped with an injection port 18; the top of the lower mold 1 has multiple first grooves. 19; A cylinder 110 is fixedly connected to the inner sidewall of the bottom of multiple first grooves 19; Multiple air rods 111 are installed on the top of the cylinders 110; Guide plates 112 are fixedly connected to the top of the multiple air rods 111; During operation, multiple guide holes 11 are opened on the top of the lower mold 1, and guide rods 14 are slidably connected to the sidewalls of the multiple guide holes 11. The upper mold 16 is fixedly connected to the top of the multiple guide rods 14. The lower mold 1 and the upper mold 16 are connected through the guide holes 11 and the guide rods 14. Multiple positioning pins 12 are fixedly connected to the top of the lower mold 1, and multiple positioning holes 15 are opened on the bottom of the upper mold 16. 2 corresponds to the positioning hole 15 and is used to position the connection between the lower mold 1 and the upper mold 16. A mold core 13 is fixedly connected to the top of the lower mold 1 for shaping the mold. A cavity 17 is opened at the bottom of the upper mold 16, and an injection port 18 is opened at the bottom of the cavity 17. The material required for the mold is injected into the cavity 17 through the injection port 18. Multiple first grooves 19 are opened at the top of the lower mold 1. Cylinders 110 are fixedly installed on the inner sidewalls of the bottom of the multiple first grooves 19. Multiple air rods 111 are installed on the top of the air rods 110, and guide plates 11 are fixedly connected to the top of the multiple air rods 111. 2. When the connector is injection molded, the upper mold 16 covers the lower mold 1 by engaging the guide rod 14 on the upper mold 16 with the guide hole 11 on the lower mold 1. After injection molding is completed, the upper mold 16 needs to be lifted. During the injection molding process, it is difficult to lift the upper mold 16 because the internal structure is sealed. The cylinder 110 drives the air rod 111 to push the guide plate 112 upward, so that the guide plate 112 contacts the bottom of the upper mold 16 and lifts the bottom of the upper mold 16, giving the bottom of the upper mold 16 a force, making it easier to lift the upper mold 16, and thus facilitating the demolding of the mold.
[0027] Furthermore, such as Figure 2 and Figure 5As shown, the lower mold 1 has multiple second grooves 2 on its top; multiple springs 21 are fixedly connected to the inner sidewalls of the bottom of the multiple second grooves 2; and a pad 22 is fixedly connected to the top of the multiple springs 21. During operation, multiple second grooves 2 are provided on the top of the lower mold 1, multiple springs 21 are fixedly connected to the inner sidewalls of the bottom of the second grooves 2, and a pad 22 is fixedly connected to the top of the multiple springs 21. When the upper mold 16 covers the lower mold 1, the bottom of the upper mold 16 presses the pad 22, causing the pad 22 to press the springs 21 downward. After the connector injection molding is completed, the upper mold 16 separates from the lower mold 1. During the separation process, the springs 21 release pressure, causing the pad 22 to lift the upper mold 16 upward. By lifting the upper mold 16, the upper mold 16 and the lower mold 1 can be separated more easily, allowing the model to be demolded better.
[0028] Furthermore, such as Figure 2 As shown, a sealing gasket 3 is fixedly connected to the top of the lower mold 1; the sealing gasket 3 is sleeved on the side wall of the mold core 13 to seal the side wall of the mold core 13; during operation, the sealing gasket 3 is fixedly connected to the top of the lower mold 1 and sleeved on the side wall of the mold core 13. When the connector is injection molded, it is necessary to ensure that the side wall of the mold core 13 is in a sealed state. The sealed state of the mold core 13 is conducive to better plasticity of the model. At the same time, when the mold is not in use, it needs to be sealed and stored to avoid oxidation or water vapor corrosion.
[0029] Furthermore, such as Figure 4 As shown, a water tank 4 is installed on the top of the cavity 17; the water tank 4 is square and is used to cool the mold core 13; during operation, the water tank 4 is installed on the top of the cavity 17, and water and coolant are added inside the water tank 4. When the connector is injection molded, high-temperature materials need to be added. After injection, the model needs to be cooled and solidified. By installing the water tank 4 on the top of the cavity 17, the model can be cooled and solidified quickly, making the model more stable and robust.
[0030] Furthermore, such as Figure 4 As shown, an air blowing pipe 5 is installed on the top of the cavity 17; the opening of the air blowing pipe 5 is set towards the mold core 13, and it is used to blow mold the mold core 13; during operation, the air blowing pipe 5 is installed on the top of the cavity 17, and the opening of the air blowing pipe 5 is set towards the mold core 13. After injection molding is completed, the model is blown with air through the air blowing pipe 5, which can make the model better separate from the mold core 13 and facilitate quick removal of the model.
[0031] Furthermore, such as Figure 4As shown, the cavity 17 has multiple vent holes 6 on its side wall; the multiple vent holes 6 are arranged linearly to vent the cavity 17; during operation, multiple vent holes 6 are opened on the side wall of the cavity 17. During the process of injection molding material into the mold core 13, the air inside the mold core 13 needs to be quickly discharged to prevent trapped air from causing insufficient filling and scorching. The air inside the mold core 13 can be quickly discharged through the multiple vent holes 6.
[0032] Working principle: During operation, multiple guide holes 11 are opened at the top of the lower mold 1, and guide rods 14 are slidably connected to the side walls of the multiple guide holes 11. The upper mold 16 is fixedly connected to the top of the multiple guide rods 14. The lower mold 1 and the upper mold 16 are connected through the guide holes 11 and guide rods 14. Multiple positioning pins 12 are fixedly connected to the top of the lower mold 1, and multiple positioning holes 15 are opened at the bottom of the upper mold 16. The multiple positioning pins 12 and positioning holes 15 correspond to each other and are used to position the connection between the lower mold 1 and the upper mold 16. A mold core 13 is fixedly connected to the top of the lower mold 1 for shaping the mold. A cavity 17 is opened at the bottom of the upper mold 16, and an injection port 18 is opened at the bottom of the cavity 17. The material required for the mold is injected into the cavity 17 through the injection port 18. Multiple first grooves 19 are formed at the top. Cylinders 110 are fixedly installed on the inner sidewalls of the bottom of the multiple first grooves 19. Multiple air rods 111 are installed on the top of the cylinders 110. Guide plates 112 are fixedly connected to the top of the multiple air rods 111. When the connector is injection molded, the upper mold 16 covers the lower mold 1 by engaging the guide rods 14 on the upper mold 16 with the guide holes 11 on the lower mold 1. After injection molding, the upper mold 16 needs to be lifted. During the injection molding process, it is difficult to lift the upper mold 16 due to the sealed internal structure. The cylinders 110 drive the air rods 111 to push the guide plates 112 upward, so that the guide plates 112 contact the bottom of the upper mold 16 and lift the bottom of the upper mold 16, giving the bottom of the upper mold 16 a force. The upper mold 16 is lifted more easily, facilitating mold demolding. During operation, multiple second grooves 2 are provided on the top of the lower mold 1. Multiple springs 21 are fixedly connected to the inner sidewall of the bottom of the second grooves 2. A pad 22 is fixedly connected to the top of the multiple springs 21. When the upper mold 16 covers the lower mold 1, the bottom of the upper mold 16 presses the pad 22, causing the pad 22 to press the springs 21 downwards. After the connector injection molding is completed, the upper mold 16 separates from the lower mold 1. During the separation process, the springs 21 release pressure, causing the pad 22 to lift the upper mold 16 upwards. By lifting the upper mold 16, the upper mold 16 can be separated from the lower mold 1 more easily, making the mold easier to demold. During operation, a sealing gasket 3 is fixedly connected to the top of the lower mold 1. The sealing gasket 3 is fitted onto the mold. During injection molding of the connector, the sidewalls of the core 13 must be sealed. A sealed core 13 promotes better plasticity of the mold. When not in use, the mold must be stored in a sealed manner to prevent oxidation or moisture corrosion. During operation, a water tank 4 is installed on top of the cavity 17, filled with water and coolant. High-temperature materials are used during connector injection, and the mold needs to cool and solidify after injection. The water tank 4 on top of the cavity 17 allows for rapid cooling and solidification, resulting in a more stable and robust mold. During operation, an air blower 5 is installed on top of the cavity 17, with its opening facing the core 13. After injection molding, air is blown onto the mold through the air blower 5.This allows for better separation of the mold from the mold core 13, facilitating quick mold removal. During operation, multiple vent holes 6 are opened on the side wall of the cavity 17. During the injection of molding material into the mold core 13, air inside the mold core 13 needs to be quickly expelled to prevent trapped air from causing insufficient filling and scorching. The multiple vent holes 6 allow for rapid expulsion of air from the mold core 13.
