Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, and in particular to a production mold for a multi-slag bag venting type scooter frame rear rocker arm. Background Technology

[0002] The rear swingarm is a crucial component of the scooter frame, primarily connecting the rear wheel to the frame. Located at the rear of the scooter, its design effectively transmits power. When the scooter's power system drives the rear wheel, the swingarm ensures smooth power transmission, allowing the scooter to move forward. The manufacturing process requires molds for the rear swingarm. These molds typically use high-quality mold steel as raw material. For complex curved surfaces, electrical discharge machining (EDM) may be used, employing the principle of electro-erosion to create shapes difficult to achieve with traditional machining. However, injection molding is often necessary to produce the frame and rear swingarm.

[0003] The existing injection molding structure for scooter rear swingarms mainly consists of an injection mold, an injection molding machine, and related auxiliary equipment. The injection mold is the core component, typically including a fixed mold base plate, a fixed template, a moving template, and a base plate for the moving mold base plate. The fixed mold base plate is connected to the fixed template of the injection molding machine, and the fixed template has a cavity for forming the shape of the rear swingarm. Its precise contour design ensures that the shape of the rear swingarm is accurately shaped. The moving template has a core installed. When the mold is closed, the core and the cavity cooperate to form a complete rear swingarm forming space. In addition, the mold is equipped with cooling water channels, which can quickly cool the product after injection molding and accelerate the molding process. However, this cannot solve the problem of air not being able to be expelled during the injection molding process, resulting in a large number of bubbles and waste residue. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a multi-slag-filled venting type scooter frame rear swingarm production mold, which aims to improve the problem of air not being able to be discharged during the injection molding process in the prior art, resulting in a large number of bubbles and waste residues.

[0005] To achieve the above objectives, this utility model adopts the following technical solution: a production mold for a multi-slag bag exhaust-type scooter frame rear swingarm, including a front mold. The front mold has multiple connecting holes inside, and a slag bag (first type) is formed near the edge of each connecting hole. The slag bag (first type) has multiple circular holes near its edge. A straight air outlet pipe is connected to the top of each circular hole, and an L-shaped air outlet pipe is connected to the inner wall of each circular hole. An exhaust mesh is fixedly connected to the top of the inner wall of the L-shaped air outlet pipe. A second slag bag (second type) is slidably connected to the bottom of the front mold. Square holes are formed on the left and right sides of the top of the second slag bag. A cover plate is slidably connected to the rear end of the front mold. A mold groove is formed at the rear end of the front mold. Fixing mechanisms are provided at both the left and right ends of the front mold for fixing operations.

[0006] As a further description of the above technical solution:

[0007] The fixing mechanism includes a fixing plate. The left side of the fixing plate is fixedly connected to the lower right side of the front mold. A rotating rod is fixedly connected between adjacent fixing plates. The outer wall of the rotating rod is rotatably connected to a rotating plate. A rotating plate is fixedly connected to the rear end of the rotating plate. A threaded hole I is opened on the right side of each rotating plate. An external thread is threaded to the inner wall of the threaded hole I. A bolt is fixedly connected to the right side of the external thread. A threaded hole II is threaded to the outer wall of the external thread.

[0008] As a further description of the above technical solution:

[0009] The rear end of the front mold is slidably connected to the rear mold, and the lower ends of the left and right sides of the rear mold are slidably connected to the rotating plate.

[0010] As a further description of the above technical solution:

[0011] Multiple buckles are fixedly connected to the top front side of the rear mold. The outer wall of the buckle is slidably connected to the rear end of the front mold. Multiple rear rocker arms are provided on the rear side of the front mold. The inner wall of the rear rocker arm is slidably connected to the outer wall of the buckle.

[0012] As a further description of the above technical solution:

[0013] A fixed cylinder is fixedly connected to the front side of the front mold near the middle, and the front side of the fixed cylinder is slidably connected to the sliding rod.

[0014] As a further description of the above technical solution:

[0015] A spring is slidably connected to the outer wall of the sliding rod, a cylindrical sleeve is fixedly connected to the front side of the spring, and a push plate is fixedly connected to the front side of the cylindrical sleeve.

[0016] As a further description of the above technical solution:

[0017] The rear end of each push plate is fixedly connected to multiple push rods, and the front side of each push plate is fixedly connected to a push column.

[0018] As a further description of the above technical solution:

[0019] The top of the rear mold is connected to a liquid storage tank, and the top of the liquid storage tank is connected to a liquid injection port.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the front mold and the rear mold are first joined together and then secured by a fixing mechanism. Liquid is then injected through the injection port, entering the storage tank and slowly flowing into the mold groove. The liquid then flows through the mold groove into various connecting holes and into the slag bag. At this point, the slag bag is vented through a circular hole, and the gas is discharged through the L-shaped vent pipe and the exhaust net. The liquid waste remains inside the slag bag. After the operation is completed, the cover is opened and removed to clean the waste in the slag bag. After cleaning, the cover is reinstalled for continued use. This design achieves greater stability during injection molding and improves the success rate of injection molding.

[0022] 2. In this utility model, when it is necessary to open, firstly, the front mold and the rear mold are locked together, and then the bolt is rotated. At this time, the bolt will drive the external thread to rotate, and then the external thread will rotate in the threaded hole one of the rotating plate until the external thread disengages from the threaded hole two. Then, the rotating plate is rotated, and the rotating plate will rotate along the rotating rod. At this time, with the cooperation of the fixing plate, the rotating plate is opened, and then the front mold and the rear mold are separated. When it is necessary to fix, the front mold and the rear mold are locked together, and then the rotating plate is rotated back along the rotating rod. Then, the bolt is rotated back into the threaded hole two. At this time, the front mold and the rear mold will be fixed, achieving a more secure fixation. Attached Figure Description

Then rotate the rotating plate 204, and the rotating plate 204 will rotate along the cylindrical sleeve 203 in the rotating rod 202. At this time, with the cooperation of the fixing plate 201, the rotating plate 204 will open, and then the front mold 1 and the rear mold 13 will separate. When fixing is required, the same method is used: snap the front mold 1 and the rear mold 13 together, then rotate the rotating plate 204 back along the rotating rod 202, and then rotate the bolt 206 back into the threaded hole 208. At this time, the front mold 1 and the rear mold 13 will be fixed, achieving a more secure fixation.
