Description

Technical Field

[0001] The utility model relates to the technical field of bellows manufacturing devices, in particular to a forming die for producing bellows. Background Art

[0002] Corrugated pipes, also known as corrugated pipes or corrugated pipes, are usually made of materials such as high-density polyethylene (HDPE) or polyvinyl chloride (PVC). Corrugated pipes have the advantages of being light, corrosion-resistant, electrically insulating and low-cost. They are widely used in some specific application fields, such as cable protection, cable ducts, drainage systems, etc. Plastic corrugated pipes can provide a certain degree of flexibility and pressure resistance through their corrugated structure, and are suitable for some occasions that require bending, expansion or external force.

[0003] During the production of bellows, the molten raw material needs to be injected into multiple groups of mutually closed bellows molds, and then vacuum pressure is applied to them to evenly distribute the raw material inside the molds. Finally, the formed bellows can be cooled and hardened. However, existing bellows molds usually do not have a cooling function. Therefore, after the bellows are separated from the mold, additional cooling and hardening treatment is required, which prolongs the production cycle and reduces production efficiency.

[0004] In addition, the bellows molds are used in groups, one of which is provided with a slot and the other is provided with a pin. When the two molds are closed, the pin enters the slot for positioning. In order to reduce wear, lubricating oil is applied to the pin and the slot. However, after long-term use, the lubricating oil will flow into the inside of the mold, which will cause contamination of the outer wall of the bellows and affect the appearance of the product.

[0012] Compared with the existing technology, the beneficial effects of the utility model are:

[0013] (1) The utility model uses a water pump to draw the coolant in the coolant tank into the cooling chamber for circulation, so that the bellows can obtain a certain cooling and hardening effect before being separated from the first mold body and the second mold body. After the first mold body is separated from the second mold body, the bellows can maintain a certain hardness, reduce the risk of deformation, and improve the molding quality of the bellows. It can also accelerate the cooling and hardening process of the bellows, shorten the production cycle, and improve production efficiency.

The coolant inside the coolant tank 103 is pumped into the cooling cavity 102 for circulation through the water pump 104. Therefore, the bellows can be cooled and hardened to a certain extent before being separated from the first mold body 100 and the second mold body 101, thereby improving the molding quality of the bellows, accelerating the cooling and hardening process of the bellows, shortening the production cycle, and improving production efficiency.

The outer surfaces of the first mold body 100 and the second mold body 101 are provided with oil drain holes connected to the oil groove 109, and the interior of the oil drain hole is provided with a plug 110. When the lubricating oil collected inside the oil groove 109 reaches a certain level, the plug 110 can be opened to discharge the lubricating oil.

[0025] A ventilation pipe 200 is installed on the top of the coolant tank 103, and a dustproof net 201 is arranged inside the ventilation pipe 200. Through the arrangement of the ventilation pipe 200, the coolant inside the coolant tank 103 can be cooled. Through the arrangement of the dustproof net 201, dust and other impurities can be prevented from entering the coolant tank 103, affecting the quality of the coolant and causing the water pump 104 and the pipeline to be blocked.

Through the arrangement of the support rod 500, the upper end of the connecting shaft 301 can be supported, so that the connecting shaft 301 is more stable when rotating.

[0026] A motor 300 is installed at the bottom of the coolant tank 103, and a connecting shaft 301 is rotatably connected inside the coolant tank 103, and the connecting shaft 301 is connected to the output shaft of the motor 300.

When impurities such as dust or lint are attached to the outer surface of the dustproof net 201, it will directly affect the passage. The circulation of air inside the air duct 200 affects the heat dissipation effect of the coolant. At this time, the electric push rod 603 can be started, and the electric push rod 603 drives the positioning block 605 to extend in the direction of the positioning groove 606.

At this time, the connecting shaft 301 can drive the brush plate 602 to rotate to clean the surface of the dustproof net 201, thereby ensuring the circulation of air inside the ventilation duct 200.

[0029] The working principle of the utility model is as follows: when using the device, first install multiple sets of first mold bodies 100 and second mold bodies 101 on the processing equipment. When the equipment drives multiple sets of first mold bodies 100 and second mold bodies 101 to close, the melted raw materials are injected into the cavity formed by the closing of multiple sets of first mold bodies 100 and second mold bodies 101 through the injection molding machine, and then vacuum pressure is applied to it to make the raw materials evenly distributed inside the cavity. At the same time, the water pump 104 is started to drive the coolant inside the coolant tank 103 to enter the cooling cavity 102 from the water inlet pipe 105, and the coolant is then discharged from the water outlet pipe 101. 06 flows back into the coolant tank 103, so that the coolant can circulate, and the motor 300 drives the fan blade 302 and the stirring blade 400 to rotate at the same time, the stirring blade 400 stirs the coolant, so that the internal heat is quickly discharged outward, and the fan blade 302 replaces the air inside the coolant tank 103, so as to achieve the purpose of quickly cooling the coolant. Therefore, when the coolant circulates inside the cooling chamber 102, it can cool the bellows, and the cooling effect is good, so the molding quality of the bellows can be improved, and the cooling and hardening process of the bellows can be accelerated, the production cycle can be shortened, and the improvement In order to improve production efficiency, when the lubricating oil in the latch 108 and the slot 107 flows downward, since the inside of the oil groove 109 is an inclined structure, the lubricating oil flows along the inclined inner wall of the oil groove 109 to the inside of the oil groove 109, so the lubricating oil can be collected to prevent the lubricating oil from flowing into the inside of the first mold body 100 and the second mold body 101, causing the outer wall of the product to be contaminated. When the lubricating oil collected in the oil groove 109 reaches a certain level, the plug 110 can be opened to discharge the lubricating oil. When the outer surface of the dustproof net 201 is attached with impurities such as dust or lint, it will directly affect the air inside the ventilation pipe 200. The circulation of the coolant will be affected, thereby affecting the heat dissipation effect of the coolant. At this time, the electric push rod 603 can be started, and the electric push rod 603 drives the positioning block 605 to extend in the direction of the positioning groove 606. Since the spring telescopic rod 604 has a certain degree of elasticity, when the positioning groove 606 is rotated to correspond exactly to the positioning block 605, the spring telescopic rod 604 can drive the positioning block 605 to insert into the positioning groove 606, thereby achieving the purpose of connecting the connecting shaft 301 with the rotating shaft 601. At this time, the connecting shaft 301 can drive the brush plate 602 to rotate to clean the surface of the dustproof net 201, thereby ensuring the circulation of air inside the ventilation duct 200.
