Description

Technical Field

[0001] The utility model relates to the technical field of injection molding machines, in particular to an injection molding device for laptop covers. Background Art

[0002] An injection molding machine is an important industrial equipment. Its working principle is similar to that of a syringe. Through the thrust of a screw (or plunger), the plastic in a molten state that has been plasticized is injected into a closed mold cavity. After curing and shaping, the product is obtained. Injection molding machines are widely used in the production of plastic products, such as household appliance casings, automotive parts, toys, daily necessities, etc.

[0003] In view of the above and related existing technologies, the inventor believes that the following defects often exist: when producing laptop covers, an injection molding machine is generally used. Since most injection molding machines will push the covers and drop them into a collection bucket after production, and the capacity of the collection bucket is limited, it needs to be replaced after a period of production, which is likely to cause the problem of cumbersome operation. Therefore, an injection molding device for laptop covers is proposed to solve the above problems. Summary of the Utility Model

[0004] In order to make up for the deficiencies of the existing technology and solve at least one of the technical problems proposed in the background art.

[0005] The technical solution adopted by the utility model to solve its technical problems is as follows: an injection molding device for laptop covers according to the utility model includes a machine body and a guiding device. A plastic extruder is fixedly connected to the upper surface of the machine body, and a molding part is fixedly connected to the upper surface of the machine body. A guiding device is provided on the surface of the machine body. The guiding device includes a placement plate. The side wall of the placement plate is fixedly connected to the side wall of the machine body. A rotating plate is rotatably connected to the surface of the placement plate. A plurality of guide rollers are rotatably connected to the inner wall of the rotating plate. A buffer sleeve is fixedly connected to the surface of the guide rollers. The cover will move on the surface of the buffer sleeve on the guide rollers, and the guide rollers will rotate on the inner surface of the rotating plate. By setting the placement plate, the rotating plate, the guide rollers and the buffer sleeve, it is convenient to convey the cover, and at the same time, it can also reduce the possibility of the cover being damaged due to too high a falling height.

[0006] Preferably, two support frames are fixedly connected to the side wall of the machine body. The two support frames are located on both sides of the rotating plate relative to the rotating plate. A moving block is fixedly connected to the position of the side wall of the rotating plate close to the support frame. The surface of the moving block is movably connected to the inner surface of the support frame. The moving block moves on the inner wall of the support frame. By setting the moving block and the support frame, the angle and position of the rotating plate can be restricted.

[0007] Preferably, one end of the moving block away from the rotating plate is fixedly connected with a placing block, and the placing block is located on the side wall of the support frame. When the moving block moves, the moving block drives the placing block to move, and the placing block can reduce the situation that the moving block disengages from the support frame.

[0008] Preferably, an inserting block is slidably connected to the inner wall of the placing block, and the inserting block is inserted into the inner walls of the support frame and the moving block. Push the inserting block to make it slide on the inner wall of the placing block, and the inserting block is inserted into the inner walls of the support frame and the moving block, and the inserting block can limit the position of the moving block in the support frame.

[0009] Preferably, a spring is fixedly connected between the side wall of the inserting block and the side wall of the placing block. A plurality of insertion holes are formed on the surface of the support frame, and the inserting block is inserted into the inner wall of the insertion hole of the support frame. When using the inserting block, release the inserting block and the spring drives the inserting block to slide. By setting the spring, the inserting block can be driven and its position can be limited at the same time.

[0010] Preferably, a heat dissipation device is provided on the side wall of the placing plate. The heat dissipation device includes a fixing plate, and the side wall of the fixing plate is fixedly connected to the side wall of the placing plate. A plurality of fans are inserted into the inner wall of the fixing plate. Start the fans, and by setting the fans, the machine cover can be dissipated heat.

[0011] Preferably, two threaded rods are rotatably connected to the surface of the fixing plate, and two opposite threaded lines are provided on the surface of the threaded rods. Two clamping plates are threadedly connected to the surface of the two threaded rods. The bottom end of the threaded rod is fixedly connected with a turntable, and the clamping plate is sleeved on the surface of the fan. The threaded rod rotates in the inner wall of the clamping plate, and the clamping plate is sleeved on the surface of the fan. By setting the threaded rod, the clamping plate and the turntable, the position of the fan can be limited.

After the rotating plate rotates to a suitable angle, release the inserting block and the spring rebounds. The spring drives the inserting block to move, and the inserting block is inserted into the inner walls of the support frame and the moving block. Then attach the conveyor belt to the rotating plate, and then start the whole device to produce the notebook machine cover. When the machine cover falls, it will land on the surface of the buffer sleeve. The machine cover will also move its position due to gravity. When the machine cover moves, it will drive the guide roller to rotate on the inner surface of the rotating plate. By setting the whole device, the machine cover can be conveniently guided to the conveyor belt, thereby reducing the operation of frequently replacing the collection bucket. At the same time, the buffer sleeve can also reduce the situation that the machine cover is damaged by knocking.

[0014] 2. When the present utility model is in production, the fan is pushed to insert it into the inner wall of the fixed plate, and then the turntable is pushed to drive the threaded rod to rotate. The threaded rod rotates within the inner walls of the two clamping plates, and the two clamping plates are sleeved on the surface of the fan. Then the fan is started to blow air on the machine cover. If it is necessary to rotate the two threaded rods together, the belt is sleeved on the surfaces of the two turntables, and then the belt is pulled to drive the two turntables to rotate together. The turntable drives the threaded rod to rotate. By setting the fan, the heat dissipation speed of the machine cover can be increased. BRIEF DESCRIPTION OF THE DRAWINGS
