Description

Technical Field

[0001] This utility model belongs to the field of mold technology, specifically an electrostatic spraying mold for rubber shoe production. Background Technology

[0002] Rubber shoes are shoes made of rubber materials, usually consisting of a sole and an upper. Rubber shoes are characterized by their wear resistance, corrosion resistance, and simple manufacturing process. The production process of rubber shoe soles requires the use of rubber shoe molds for injection molding.

[0003] In the use of existing rubber shoe production molds, molten rubber raw material is usually injected into the mold after it has been opened. After the plastic cools and solidifies in the mold, the mold is opened and the formed rubber shoe is taken out. During long-term use and observation, it was found that the existing rubber shoe production molds have a problem with slow molding speed due to the slow cooling rate of the rubber raw material in the mold.

[0004] Therefore, this utility model provides an electrostatic spraying mold for rubber shoe production. Utility Model Content

This step, by setting up a cooling box to connect the liquid outlet pipe and the water pump to the liquid inlet pipe, can cool and recycle the water flowing out of the liquid guide tank, thereby reducing water waste and improving water utilization. At the same time, the cold water can make the mold seat temperature drop faster, thereby increasing the molding speed of the rubber shoe.

[0008] Preferably, a pair of slide rails are fixed to the inner side wall of the cooling box; a first filter screen is placed on the side wall of the pair of slide rails; this step can filter the water entering the cooling box by setting the slide rails and the first filter screen, so as to reduce the situation where impurities such as injection molding residue in the water adhere to the surface of the refrigeration pipe, resulting in a reduction in the cooling effect.

[0009] Preferably, a blower box is fixedly connected to the side wall of the mold box; the side wall of the blower box has multiple ventilation holes; a fan is fixedly connected to the inner side wall of the blower box; this step, by setting up the blower box and the fan to blow air onto the molded rubber shoes, can make the temperature of the rubber shoes drop faster, thereby improving the molding effect of the rubber shoes.

[0011] Preferably, a plurality of fixing rods are fixedly connected to the side wall of the air box; a second filter screen is detachably installed at the end of the plurality of fixing rods; this step, by setting the second filter screen, can filter the airflow entering the air box, reduce the situation where some dust and other impurities in the airflow are blown onto the surface of the rubber shoes and cause pollution, thereby improving the cleanliness of the surface of the rubber shoes.

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.

[0023] Specific implementation examples are given below.

[0024] like Figures 1 to 2 As shown in the embodiment of this utility model, an electrostatic spraying mold for producing rubber shoes includes a mold box 1; a liquid guiding groove 11 is provided inside the mold box 1; a mold base 12 is fixedly connected to the inner wall of the mold box 1; a mold cover 13 is hinged to the top of the mold base 12; an injection molding pipe 14 is connected to the top of the mold cover 13; an inlet pipe 15 is connected to the side wall of the mold box 1; an outlet pipe 16 is connected to the side wall of the mold box 1; the inlet pipe 15 and the outlet pipe 16 are staggered; a fixing plate 17 is fixedly connected to the side wall of the mold box 1; during operation, an external water source is connected through the inlet pipe 15 to allow water to flow into the liquid guiding groove 11, and then... The raw material is then injected into the mold base 12 and mold cover 13 through the injection tube 14. At this time, water is in the liquid guide trough 11 and comes into contact with the mold base 12, which can cool the mold base 12 and the raw material inside it. Then the mold cover 13 can be opened to take out the molded rubber shoe. After processing, the liquid outlet pipe 16 can be opened to drain the water. This step, by setting the liquid inlet pipe 15 and the liquid guide trough 11, allows water to come into contact with the mold base 12 and cool the mold base 12 after injection molding, so that the temperature inside the mold base 12 drops faster, thereby increasing the molding speed of the rubber shoe in the mold base 12 and improving the efficiency of rubber shoe production.

[0025] like Figures 1 to 3 As shown, a cooling box 2 is fixedly connected to the top of the fixed plate 17; the side wall of the cooling box 2 is connected to the outlet pipe 16; a refrigeration pipe 21 is fixedly connected to the inner side wall of the cooling box 2; a water pump 22 is connected to the side wall of the cooling box 2; a guide pipe 23 is connected to the side wall of the water pump 22; and the guide pipe 23 is connected to the end of the inlet pipe 15. During operation, when water in the guide tank 11 is discharged from the outlet pipe 16, it enters the cooling box 2. At this time, the refrigeration pipe 21 cools the water entering the tank, and then the water pump 22 is started to draw the water out of the cooling box 2. The water then enters the guide tank 11 again through the guide pipe 23 and the inlet pipe 15. This step, by setting the cooling box 2 to connect the outlet pipe 16 and the water pump 22 to the inlet pipe 15, can cool and recycle the water flowing out of the guide tank 11, thereby reducing water waste and improving water utilization. At the same time, the cold water can make the temperature of the mold base 12 drop faster, thus increasing the molding speed of the rubber shoe.

[0026] like Figure 3 As shown, a pair of slide rails 3 are fixed to the inner side wall of the cooling tank 2; a first filter screen 31 is placed on the side wall of the pair of slide rails 3. During operation, when water in the liquid guide tank 11 enters the cooling tank 2 from the liquid outlet pipe 16, it will pass through the first filter screen 31. At this time, the first filter screen 31 can filter the water and remove impurities such as injection molding residue contained in the water. After filtration, the first filter screen 31 can be removed, cleaned, and then reset. This step, by setting the slide rails 3 and the first filter screen 31, can filter the water entering the cooling tank 2, so as to reduce the situation where impurities such as injection molding residue in the water adhere to the surface of the refrigeration pipe 21, which leads to a reduction in the cooling effect.

[0027] like Figure 1 and Figure 4 As shown, a blower box 4 is fixedly connected to the side wall of the mold box 1; multiple ventilation holes 41 are opened on the side wall of the blower box 4; a fan 42 is fixedly connected to the inner side wall of the blower box 4; during operation, when the mold cover 13 is opened after the rubber shoe is formed, the fan 42 is started to drive the airflow from the ventilation holes 41 to the rubber shoe, which can cool down the formed rubber shoe. This step, by setting the blower box 4 and the fan 42 to blow air onto the formed rubber shoe, can make the temperature of the rubber shoe drop faster, thereby improving the forming effect of the rubber shoe.

[0028] like Figure 2As shown, a square groove 5 is provided in the middle of the mold base 12; an electric push rod 51 is fixedly connected to the inner wall of the square groove 5; a pair of top blocks 52 are fixedly connected to the end of the electric push rod 51; a pair of top grooves 53 are provided on the top of the mold base 12; during operation, the electric push rod 51 is activated to drive the top blocks 52 to move towards the top of the mold base 12. At this time, the top of the top blocks 52 will contact the bottom of the rubber shoe and can be lifted upward from the bottom after the rubber shoe is injection molded. This step, by setting the electric push rod 51 to drive the top blocks 52 to move upward, can lift the rubber shoe after it is injection molded, so as to facilitate the removal of the rubber shoe from the mold base 12.

[0029] like Figure 4 As shown, multiple fixing rods 6 are fixedly connected to the side wall of the air box 4; a second filter screen 61 is detachably installed at the end of the multiple fixing rods 6; during operation, when the blower 42 blows air onto the rubber shoes, the airflow passes through the second filter screen 61 and enters the air box 4 before being blown onto the surface of the rubber shoes. When the airflow passes through the second filter screen 61, it will be filtered to remove some dust and other impurities in the airflow. This step, by setting the second filter screen 61, can filter the airflow entering the air box 4, reduce the situation where some dust and other impurities in the airflow are blown onto the surface of the rubber shoes and cause pollution, thereby improving the cleanliness of the surface of the rubber shoes.

[0030] like Figure 3 As shown, multiple temperature-conducting plates 7 are fixed to the side wall of the refrigeration pipe 21. During operation, when the refrigeration pipe 21 cools the water in the cooling tank 2, the temperature-conducting plates 7 connected to the refrigeration pipe 21 will conduct the temperature of the refrigeration pipe 21. This step, by setting the temperature-conducting plates 7 to connect to the refrigeration pipe 21, can increase the contact range between the water in the cooling tank 2 and the refrigeration pipe 21. The temperature of the refrigeration pipe 21 can be conducted to the water through the temperature-conducting plates 7, which can improve the cooling rate of the water.

[0031] Working principle: During operation, an external water source is connected through the inlet pipe 15, allowing water to flow into the guide tank 11. Then, the raw material is injected into the mold base 12 and mold cover 13 through the injection pipe 14. At this time, the water in the guide tank 11 contacts the mold base 12, cooling it and the raw material inside. The mold cover 13 can then be opened to remove the molded rubber shoe. After processing, the outlet pipe 16 can be opened to drain the water. When the water in the guide tank 11 drains from the outlet pipe 16, it enters the cooling tank 2. The cooling pipe 21 cools the incoming water, and the water pump 22 is activated to draw the water out of the cooling tank 2. The water then flows back into the guide tank 11 through the guide pipe 23 and the inlet pipe 15. When the water in the guide tank 11 enters the cooling tank 2 through the outlet pipe 16, it passes through the first filter screen 31. 1. Water can be filtered to remove impurities such as injection molding residue. After filtration, the first filter screen 31 can be removed, cleaned, and then reset. When the mold cover 13 is opened after the rubber shoe is formed, the blower 42 is started to drive airflow from the ventilation hole 41 to the rubber shoe, which can cool the formed rubber shoe. The electric push rod 51 is started to drive the top block 52 to move to the top of the mold base 12. At this time, the top of the top block 52 will contact the bottom of the rubber shoe and can push it up from the bottom after the rubber shoe is injection molded. When the blower 42 blows air onto the rubber shoe, the airflow passes through the second filter screen 61 and enters the air box 4 before being blown onto the surface of the rubber shoe. When the airflow passes through the second filter screen 61, it will be filtered to remove some dust and other impurities. When the cooling pipe 21 cools the water in the cooling box 2, the temperature conducting plate 7 connected to the cooling pipe 21 will conduct the temperature of the cooling pipe 21.
