Description

Technical Field

[0001] This utility model belongs to the field of sealing ring production technology, and specifically relates to a sealing ring injection molding machine. Background Technology

[0002] An injection molding machine for sealing rings is a device specifically designed for manufacturing rubber or plastic sealing rings. It injects heated and molten material (such as rubber, thermoplastic elastomers, etc.) into a closed mold cavity, where it is cooled and solidified under high pressure to form the desired sealing ring shape.

[0003] Existing sealing ring injection molding machines produce sealing rings by injecting molten rubber into the interior of two closed molds, then allowing it to cool and solidify. Afterward, the molds are opened, and the sealing rings are manually removed. This manual operation is time-consuming, especially in mass production, which significantly reduces overall production efficiency. Furthermore, prolonged manual material handling not only consumes a lot of the operator's physical strength but also leads to operator fatigue and operational errors. In addition, manual material handling increases the risk of contact with high-temperature molds, which can easily cause burns or other safety accidents. Utility Model Content

[0004] In view of this, this utility model addresses the shortcomings of the prior art by providing a sealing ring injection molding machine. By setting a cooling mechanism at the upper end of the upper mold, the molten rubber inside the mold is rapidly cooled and molded, allowing the sealing ring to adhere to the side of the upper mold that is not cooled and has a higher temperature. Then, the molded sealing ring is removed and unloaded by an automatic material handling mechanism. This allows for a continuous and efficient production process without human intervention, greatly improving the production efficiency of sealing rings.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: a sealing ring injection molding machine, including a carrier box, a plurality of guide columns are provided at the upper end of the carrier box, a lower mold is provided between the outer arc surfaces of the plurality of guide columns, an injection pipe is provided in the injection hole opened at the lower end of the lower mold, a lifting plate is slidably provided between the outer arc surfaces of the plurality of guide columns, a plurality of cooling fins are provided at the lower end of the lifting plate, the plurality of cooling fins are arranged at equal intervals, an upper mold is provided between the lower ends of the plurality of cooling fins, a cooling pipe is provided in the mounting hole opened inside the plurality of cooling fins, an automatic feeding mechanism is provided at the rear side of the carrier box, an mounting plate is provided between the upper ends of the guide columns, an electric push rod one is provided at the upper end of the mounting plate, the telescopic end of the electric push rod one is connected to the upper end of the lifting plate, an electric push rod two is provided at the upper end of the sliding frame, the telescopic end of the electric push rod two is connected to the upper end of the mounting frame plate.

[0006] As a further improvement of this utility model, the automatic feeding mechanism includes a slide frame disposed on the rear side of the bearing box. A sliding frame is slidably disposed inside the slide frame, and multiple limiting posts are slidably disposed inside the sliding frame. A mounting frame plate is disposed between the lower ends of the multiple limiting posts, and multiple suction cups are disposed at the lower end of the mounting frame plate. A lead screw is rotatably disposed on the left side inside the slide frame, and the lower left end of the sliding frame is threadedly connected to the lead screw. A drive unit for driving the lead screw to rotate is disposed on the rear left end of the slide frame. The drive unit includes a motor disposed on the rear left end of the slide frame, and the output shaft of the motor is connected to the rear end of the lead screw through a coupling.

[0007] As a further improvement of this utility model, the interior of the carrier box is equipped with multiple storage boxes that slide together. Each of the multiple storage boxes has a handle on its front side. The lower end of the carrier box is equipped with multiple mounting blocks. The carrier box and the mounting blocks are fixed together by welding. The lower end of each of the multiple mounting blocks is equipped with an anti-slip pad.

[0008] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0009] Firstly, by controlling the operation of the external coolant pump, coolant is pumped into the cooling pipe. Due to the principle of thermal contraction, the sealing ring remains on the uncooled lower mold during subsequent mold opening. The operation of the first electric push rod is then activated, and its telescopic end drives the upper mold away from the interior of the lower mold. Subsequently, the operation of the motor, the second electric push rod, and the suction cup are activated to pick up the sealing ring, causing it to fall into a pre-prepared collection box. A cooling mechanism is installed at the upper end of the upper mold, which allows the molten rubber inside the mold to cool and solidify rapidly. The sealing ring adheres to the side of the upper mold that is still at a higher temperature. Then, an automatic material handling mechanism removes the formed sealing ring and unloads it. This continuous and efficient production process can be achieved without human intervention, greatly improving the production efficiency of the sealing ring.

[0010] Secondly, the cooling efficiency of the upper mold is greatly improved by using multiple sets of cooling fins to cool the unformed sealing ring on one side of the upper mold.

[0011] Thirdly, tools can be placed inside the storage box by pulling out the handle, and the mounting block at the bottom of the carrying box and the anti-slip pad at its bottom can further ensure the stability of the molding machine and improve the injection molding quality of the sealing ring.

Detailed Implementation

[0018] To better understand this utility model, the following embodiments further illustrate its content, but the scope of protection of this utility model is not limited to the embodiments described below. Numerous specific details are set forth in the following description to provide a more thorough understanding of this utility model. However, it will be apparent to those skilled in the art that this utility model can be practiced without one or more of these details.

[0019] like Figure 1 , 2 As shown in Figures 3 and 4, a sealing ring injection molding machine includes a carrier box 101. Multiple guide pillars 102 are arranged at the upper end of the carrier box 101. A lower mold 106 is arranged between the outer arc surfaces of the multiple guide pillars 102. An injection pipe 107 is installed in an injection hole at the lower end of the lower mold 106. A lifting plate 103 is slidably arranged between the outer arc surfaces of the multiple guide pillars 102. Multiple cooling fins 210 are arranged at the lower end of the lifting plate 103. An upper mold 209 is arranged between the lower ends of the multiple cooling fins 210. A cooling pipe 208 is installed in an installation hole inside the multiple cooling fins 210. An automatic feeding mechanism is arranged at the rear side of the carrier box 101. An installation plate 104 is arranged between the upper ends of the guide pillars 102. An electric push rod 105 is arranged at the upper end of the installation plate 104. The telescopic end of the electric push rod 105 is connected to the upper end of the lifting plate 103.

[0020] The automatic feeding mechanism includes a slide frame 201 located at the rear of the carrier box 101. A sliding frame 202 is slidably arranged inside the slide frame 201. Multiple limiting posts 205 are slidably arranged inside the sliding frame 202. A mounting frame plate 206 is arranged between the lower ends of the multiple limiting posts 205. Multiple suction cups 207 are arranged at the lower end of the mounting frame plate 206. The multiple suction cups 207 are located at the four corners of the mounting frame plate 206. A lead screw 203 is rotatably arranged on the left side inside the slide frame 201. The lower left end of the sliding frame 202 is threadedly connected to the lead screw 203. A drive unit for driving the lead screw 203 to rotate is arranged at the rear left end of the slide frame 201. The drive unit includes a motor 204 arranged at the rear left end of the slide frame 201. The output shaft of the motor 204 is connected to the rear end of the lead screw 203 through a coupling. An electric push rod II is arranged at the upper end of the sliding frame 202. The telescopic end of the electric push rod II is connected to the upper end of the mounting frame plate 206.

[0021] First, connect the inlet and outlet circulation pipes of the cooling pipe 208 to the inlet and outlet pipes of the coolant pump. Then, connect the injection pipe 107 to an external molten rubber injector. Subsequently, control the operation of the electric push rod 105. The telescopic end drives the upper mold 209 on the lifting plate 103 to move downward under the restriction of the guide post 102 and contact the lower mold 106 to lock the mold. Then, control the operation of the molten rubber injector and inject it into the space between the upper mold 209 and the lower mold 106 through the injection pipe 107. Then, control the operation of the external coolant pump to pump the coolant into the interior of the cooling pipe 208. The unformed sealing ring on one side of the upper mold 209 is cooled by multiple sets of cooling fins 210. Due to the principle of cold contraction, the sealing ring remains on the uncooled lower mold 106 when the mold is opened later.

[0022] Then, the electric push rod 105 is activated, and its telescopic end drives the upper mold 209 away from the interior of the lower mold 106. Subsequently, the motor 204 is activated, and its output shaft drives the lead screw 203 to rotate, thereby causing the suction cup 207 on the sliding frame 202 to be positioned at the upper end of the lower mold 106. Then, the electric push rod 2 is activated, and its telescopic end drives the suction cup 207 on the mounting frame 206 to move downward under the restriction of the limiting post 205 and contact the formed sealing ring. Then, the suction cup 207 is activated to pick up the sealing ring (the formed sealing ring is connected as a whole through the injection port). Then, the electric push rod 2 is activated to pick up the sealing ring. Then, the motor 204 is reversed, causing the sealing ring to move out of the upper end of the lower mold 106. Then, the suction cup 207 is deactivated, causing the sealing ring to fall into the pre-prepared collection box.

[0023] According to another embodiment of the present invention, such as Figure 1 , 2As shown, multiple storage boxes 108 are slidably arranged inside the carrier box 101. Each storage box 108 has a handle on its front side. Multiple mounting blocks 109 are provided at the lower end of the carrier box 101. Each mounting block 109 has an anti-slip pad at its lower end. By pulling out the handle, the storage box 108 can be opened to place tools inside. The mounting blocks 109 at the lower end of the carrier box 101 and the anti-slip pads at their lower ends can further ensure the stability of the molding machine.
