[0001] The utility model relates to the technical field of injection molds, in particular to a jig for facilitating the removal of products. Background Technique
[0002] In the manufacturing of plastic products, especially for small injection-molded parts, in order to ensure the dimensional accuracy, shape stability and batch production consistency of the products, specially designed injection jigs are required. Injection jigs are usually customized according to the characteristics of plastic materials, the design requirements of the products and the characteristics of injection molding machines.
[0003] When injection molds produce some small injection-molded parts, due to the large production volume at one time, and the injection molds are prone to sticking during use. The reasons for sticking include inappropriate temperature, rough surface of the mold cavity, static electricity on the mold surface and too fast mold opening speed, etc., which make it difficult for the ejection structure to eject all plastic parts, resulting in the interruption of the production line and thus affecting production efficiency. Content of the Utility Model
[0004] The purpose of the utility model is to provide a jig for facilitating the removal of products. After the ejection structure ejects the molded injection-molded parts, the utility model can blow down the plastic parts staying on the surface of the fixed mold through air flow, and at the same time, with the cooperation of vibration and an electrostatic elimination fan, the device is more convenient for removing products.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A jig for facilitating the removal of products, including a U-shaped plate, a moving mold and a fixed mold. A bracket is fixed on the surface of the U-shaped plate, and a plurality of springs are fixed on the surface of the bracket. One end of the spring is fixedly connected to the surface of the fixed mold. A U-shaped frame is fixed on the surface of the fixed mold, and a first cylinder is fixed on the surface of the U-shaped frame. One end of the first cylinder penetrates through the U-shaped frame and is fixed with a push plate. A plurality of ejector rods are fixed on the surface of the push plate. The ejector rods penetrate through the fixed mold. A vibration motor is fixed at the bottom of the fixed mold. A support plate is fixed above the surface of the U-shaped plate. A high-voltage generator, an electrostatic elimination air bar and a fan are fixed on the top of the support plate. The high-voltage generator is electrically connected to the electrostatic elimination air bar. A shunt pipe is communicated with the surface of the fan. Exhaust pipes are fixed on both sides of the surface of the fixed mold. A second cylinder is fixed on the surface of the U-shaped plate. One end of the second cylinder penetrates through the U-shaped plate and is fixedly connected to the moving mold.
[0006] Preferably, for the jig for facilitating the removal of products of the utility model, a collection box is slidably connected to the surface of the U-shaped plate, and an extraction slot is opened on the surface of the U-shaped plate.
[0007] Preferably, for the jig for facilitating the removal of products of the utility model, two limiting plates are fixed on the surface of the U-shaped plate, and the collection box is located between the two limiting plates.
[0008] Preferably, for the fixture of the present utility model that facilitates the removal of products, one end of the shunt pipe is communicated with a corrugated pipe, and one end of the corrugated pipe is communicated with the exhaust pipe.
[0009] Preferably, for the fixture of the present utility model that facilitates the removal of products, two guide rods penetrate through the surface of the U-shaped plate, and one end of the guide rod is fixedly connected to the surface of the moving mold.
[0010] Preferably, for the fixture of the present utility model that facilitates the removal of products, a guide rod is fixedly installed on the surface of the bracket, the guide rod slidably penetrates through the fixed mold, and a sliding sleeve is fixedly embedded on the surface of the moving mold.
[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:
[0012] In the present utility model, the second air cylinder can drive the moving mold to move towards the fixed mold. When the moving mold and the fixed mold are in contact, the spring can be compressed and deformed, so as to buffer and disperse the impact received by the fixed mold. Then, the injection molding operation is started. After the injection molding is completed, the second air cylinder drives the moving mold to reset, and then the first air cylinder is started, so that the push plate drives the ejector rod to pass through the fixed mold, so that the injection molded part can be ejected from the inside of the fixed mold. When the plastic part cannot be completely ejected, the high-voltage generator and the static eliminator air bar are started, so that the static eliminator air bar can generate a large amount of negative ions. These negative ions can be blown by the static eliminator air bar onto the surface of the plastic part, so that the negative ions and the positive static electricity on the surface of the plastic part and the fixed mold attract each other, thereby neutralizing the static charges on the surface of the plastic part and the fixed mold, so that the plastic part that is no longer adsorbed by static electricity can fall by itself. Then, the vibration motor can be started to vibrate the fixed mold. Vibration can make the plastic part attached to the surface of the fixed mold fall off more easily. And the air blower can also be started to send air into the shunt pipe, so that the air flow can be blown towards the surface of the fixed mold through the exhaust pipe, so as to further blow off the plastic parts that have not fallen off on the surface of the fixed mold through the air flow, making it easier to remove the plastic parts with this fixture.

Detailed implementation manner
[0019] Please refer to Figures 1-5 , a fixture for facilitating the extraction of products, including a U-shaped plate 1, a moving die 2 and a fixed die 5. A bracket 3 is fixed on the surface of the U-shaped plate 1, and a plurality of springs 4 are fixed on the surface of the bracket 3. One end of the spring 4 is fixedly connected to the surface of the fixed die 5. A U-shaped frame 8 is fixed on the surface of the fixed die 5, and a first cylinder 9 is fixed on the surface of the U-shaped frame 8. One end of the first cylinder 9 penetrates through the U-shaped frame 8 and is fixed with a push plate 10. A plurality of ejector rods 11 are fixed on the surface of the push plate 10. The ejector rods 11 penetrate through the fixed die 5. A vibration motor 12 is fixed at the bottom of the fixed die 5. A support plate 13 is fixed above the surface of the U-shaped plate 1. A high-voltage generator 14, a static eliminator air bar 15 and a fan 16 are fixed on the top of the support plate 13. The high-voltage generator 14 is electrically connected to the static eliminator air bar 15. A shunt pipe 17 is communicated with the surface of the fan 16. Exhaust ducts 18 are fixed on both sides of the surface of the fixed die 5. A second cylinder 20 is fixed on the surface of the U-shaped plate 1. One end of the second cylinder 20 penetrates through the U-shaped plate 1 and is fixedly connected to the moving die 2;
[0020] The second cylinder 20 can drive the moving die 2 to move towards the fixed die 5. When the moving die 2 and the fixed die 5 are in contact, the spring 4 can be compressed and deformed to buffer and disperse the impact received by the fixed die 5. Then, the injection molding operation starts. After the injection molding is completed, the second cylinder 20 drives the moving die 2 to reset, and then the first cylinder 9 is started to make the push plate 10 drive the ejector rods 11 to pass through the fixed die 5, so that the injection molded part can be ejected from the inside of the fixed die 5. When the plastic part cannot be completely ejected, the high-voltage generator 14 and the static eliminator air bar 15 are started, so that the static eliminator air bar 15 can generate a large amount of negative ions. These negative ions can be blown by the static eliminator air bar 15 onto the surface of the plastic part, so that the negative ions attract the positive static electricity on the surface of the plastic part and the fixed die 5, thereby neutralizing the static charges on the surface of the plastic part and the fixed die 5, and making the plastic part no longer adsorbed by static electricity fall off by itself. Then, the vibration motor 12 can be started to make the fixed die 5 vibrate. The vibration can make the plastic part attached to the surface of the fixed die 5 fall off more easily. And the fan 16 can also be started to send air flow into the shunt pipe 17, so that the air flow can be blown towards the surface of the fixed die 5 through the exhaust duct 18, thereby further blowing off the plastic parts that have not fallen off on the surface of the fixed die 5 by the air flow, making it easier for this fixture to take out the plastic parts.
[0021] Further, a collection box 23 is slidably connected to the surface of the U-shaped plate 1, and an extraction groove 22 is formed on the surface of the U-shaped plate 1;
[0022] The plastic parts taken out from the inside of the fixed mold 5 can fall into the inside of the collection box 23, and the setting of the extraction groove 22 enables the operator to pull out the collection box 23 from the surface of the U-shaped plate 1.
[0023] Further, two limiting plates 24 are fixed to the surface of the U-shaped plate 1, and the collection box 23 is located between the two limiting plates 24 on both sides;
[0024] The limiting plates 24 can limit the collection box 23, so that the collection box 23 can be aligned below the fixed mold 5.
[0025] Further, one end of the shunt pipe 17 is communicated with a corrugated pipe 19, and one end of the corrugated pipe 19 is communicated with the exhaust pipe 18;
[0026] The corrugated pipe 19 can be telescopically deformed, so as to ensure that when the fixed mold 5 vibrates, the gas can be normally transported into the exhaust pipe 18 through the corrugated pipe 19.
[0027] Further, two guide rods 21 penetrate through the surface of the U-shaped plate 1, and one end of the guide rod 21 is fixedly connected to the surface of the moving mold 2;
[0028] When the moving mold 2 moves, the guide rod 21 will slide on the surface of the moving mold 2, so that the moving mold 2 has better stability when moving and avoids the situation of position deviation.
[0029] Further, a guide rod 6 is fixed to the surface of the bracket 3, the guide rod 6 slidably penetrates through the fixed mold 5, and a sliding sleeve 7 is fixedly embedded on the surface of the moving mold 2;
[0030] The fixed mold 5 can slide on the surface of the guide rod 6, so that the fixed mold 5 can obtain a supporting effect and avoid the situation that the spring 4 bends downward.
[0031] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principles of the present invention shall be included in the protection scope of the present invention.
