Description

Technical Field

[0001] The utility model relates to the field of molds, and specifically refers to a guide rail mechanism for an ultra-long stroke mold. Background Art

[0002] Injection molding is a commonly used method for processing plastic molds. It involves injecting a heat-melted material into a mold cavity under high pressure and obtaining a molded product after cooling and solidification. For products with a relatively long injection depth, such as plastic test tubes, a guide rail mechanism for an ultra-long stroke mold is required to solve this problem.

[0003] The existing guide rail mechanism for ultra-long stroke molds usually passes a moving slide bar through a fixed plate and a moving plate, and fixes a concave mold plate and a convex mold plate between the fixed plate and the moving plate with screws respectively. After injection, after standing for a certain period of time, the cooled and formed product is pulled out of the mold by moving the convex mold plate, and then the finished product is pushed off the convex mold plate by a push rod inside the convex mold plate.

[0004] Although the existing guide rail mechanism for ultra-long stroke molds can maintain a relatively long injection space for products while ensuring normal demolding of the products, the push rod under the convex mold plate will occupy the space of the product thickness. When facing some ultra-long stroke molds, the required push rod space is larger, and the guide rail length of the moving slide bar is limited, resulting in the situation that the mold product cannot be fully pushed out during demolding. Summary of the Utility Model

[0005] The technical problem to be solved by the utility model is that when facing an ultra-long stroke mold, the mold product cannot be fully pushed out.

[0006] To solve the above technical problem, the technical solution provided by the utility model is: a guide rail mechanism for an ultra-long stroke mold, including a fixed plate and a moving plate. The fixed plate is internally provided with a concave mold plate, and the moving plate is internally provided with a convex mold plate corresponding to the concave mold plate. The fixed plate is connected to the moving plate through a plurality of moving slide bars. A telescopic demolding device is arranged on the side of the convex mold plate, and a moving slide rail device for controlling the movement of the telescopic demolding device is arranged between the fixed plate and the moving plate.

[0007] As an improvement, the moving slide rail device includes a single-port slideway located between the fixed plate and the moving plate and a slider that moves back and forth inside the single-port slideway. The two sides of the single-port slideway pass through the fixed plate and the moving plate, and the open end of the single-port slideway is located on the side of the fixed plate.

[0008] As an improvement, the telescopic demolding device includes a telescopic rod and a demolding slider located at the telescopic end of the telescopic rod. The demolding slider passes through the side wall of the convex mold plate, and the demolding slider and the telescopic end of the telescopic rod are welded by a welding rod.

[0009] As an improvement, the telescopic rod is connected to the sliding block through a bolt structure.

[0010] As an improvement, the movable sliding rod passes through the fixed plate and the movable plate, and the concave template and the convex template are connected through a pin structure.

[0011] As an improvement, the fixed plate and the concave template, as well as the movable plate and the convex template, are all connected through a bolt structure.

[0012] The advantages of the present utility model compared with the prior art are as follows: The device demolds the mold product through the demolding slider of the telescopic demolding device, and adjusts the demolding push points of different products through the telescopic rod. When the convex template withdraws from the concave mold, the slider retreats to the solid side of the single-port slideway along with the convex template. Through the block of the solid side of the single-port slideway, the position of the fixed demolding slider is fixed, so that the product is separated from the convex template. When the convex template is pushed into the concave template, the slider slides towards the concave template accordingly, thereby expanding the space occupied by the ejector rod.

[0018] The following further describes the present utility model in detail with reference to the drawings.

[0019] As shown in the specification appendix Figure 1 、 2As shown, it includes a fixed plate 1 and a moving plate 2. Inside the fixed plate 1, there is a concave template 3. Inside the moving plate 2, there is a convex template 4 corresponding to the concave template 3. The fixed plate 1 is connected to the moving plate 2 through a plurality of moving slide rods 5. On the side of the convex template 4, there is a telescopic demolding device 6. Between the fixed plate 1 and the moving plate 2, there is a moving slide rail device 7 for controlling the movement of the telescopic demolding device 6. The moving slide rods 5 pass through the fixed plate 1 and the moving plate 2. The concave template 3 and the convex template 4 are connected through a pin structure. The fixed plate 1 and the concave template 3, as well as the moving plate 2 and the convex template 4, are all connected through a bolt structure. On both sides of the fixed plate 1 and the moving plate 2 passing through the moving slide rods 5, the convex template 4 inserts pins on the convex mold side into the pin holes around the concave template 3, and a sealed connection is made through the sliding between the bodies of the concave template 3 and the convex template 4.

[0020] As shown in the attached drawings of the specification Figure 3 、 4 As shown, the moving slide rail device 7 includes a single-port slideway 71 located between the fixed plate 1 and the moving plate 2 and a slider 72 that moves back and forth inside the single-port slideway 71. Both sides of the single-port slideway 71 pass through the fixed plate 1 and the moving plate 2. The open end of the single-port slideway 71 is located on the side of the fixed plate 1. The telescopic demolding device 6 includes a telescopic rod 61 and a demolding slider 62 located at the telescopic end of the telescopic rod 61. The demolding slider 62 passes through the side wall of the convex template 4. The demolding slider 62 and the telescopic end of the telescopic rod 61 are welded by a welding rod. The telescopic rod 61 is connected to the slider 72 through a bolt structure. Through the slider 62 inside the single-port slideway 71, the lower telescopic demolding device 6 makes a linear reciprocating motion.

[0021] When the present utility model is specifically implemented, the slider 72 is slid into the single-port slideway 71 from the open end, the telescopic rod 61 is fixed below the slider 72 using screws, and the demolding slider 62 is welded to the telescopic end of the telescopic rod 61 using a welding rod; the moving slide rod 5 and the moving slide rail device 7 are respectively inserted into the slide rod hole and the slide rail hole of the fixed plate 1, and the other ends of the moving slide rod 5 and the moving slide rail device 7 are respectively fixed in the slide rod hole and the slide rail hole of the moving plate 2; the convex template 4, the moving plate 2, the concave template 3, and the fixed plate 1 are tightened using screws, and the direction of the demolding slider 62 is consistent with the direction of the slider groove of the convex template 4.

[0022] During use, the moving plate 2 moves towards the fixed plate on the moving slide rod 5. During the movement, the demolding slider 62 is engaged in the slider groove of the convex template 4. Under the push of the moving plate 2, the slider 72 makes a linear sliding movement in the single-port slideway 71. After the concave template 3 and the convex template 4 are hermetically connected, the demolding slider 62 is hermetically connected to the slider groove of the convex template 4 under the pressure of the moving plate 2. After injecting the melted plastic water and cooling it, the moving plate 2 retracts. At this time, the demolding slider 62 is blocked at both ends by the product and the convex template 4, causing the slider 72 to slide towards the convex template 4 side under the drive of the demolding slider 62 and stop sliding when reaching the closed side of the single-port slideway 71. At this time, the convex template continues to retract, while the product is fixed in place under the block of the demolding slider 62. When the convex template completely exits the open end of the product, the product automatically falls, completing the demolding. After the staff takes out the product, repeat the above operations. Compared with the traditional structure of using a push rod to eject the product, the structure of this device can eliminate the ejection action during demolding, so that there is no need to set a push rod structure inside the convex template 4, expanding the internal space inside the mold device and making the mold have a longer stroke.

[0023] The above describes the present invention and its implementation manners. Such description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. All in all, if those of ordinary skill in the art are inspired by it and design similar structural manners and embodiments without creative work without departing from the purpose of the present invention creation, they shall fall within the protection scope of the present invention.
