Description

Technical Field

[0001] This utility model relates to the field of injection molding, and in particular to an auxiliary structure for blanking injection molds for components of hydraulic equipment. Background Technology

[0002] Injection molding is a method of shaping industrial products. Products are typically produced using rubber injection molding and plastic injection molding. Injection molding can also be divided into injection molding compression molding and die casting.

[0003] After injection molding, the product needs to be removed from the mold. However, the existing unloading method often involves manual unloading by workers, which lacks automation and results in low unloading efficiency, thus affecting production efficiency. Utility Model Content

[0004] The technical problem to be solved by this utility model is to overcome the defects of the existing technology. This utility model proposes an auxiliary structure for the blanking of injection molds for hydraulic equipment components.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is: a material feeding auxiliary structure for injection mold of hydraulic equipment components, including a U-shaped worktable, a mold cavity fixed on the bottom surface of the worktable, a liftable template set at the top of the worktable corresponding to the position of the mold cavity, a telescopic rod and an electric cylinder respectively set on both sides of the bottom of the worktable, a support plate located in the mold cavity and slidably connected to the top of the telescopic rod and the electric cylinder, and a reciprocating push plate set on the worktable, and when the telescopic rod and the electric cylinder are extended to their maximum length, the bottom surface of the push plate contacts the top surface of the support plate.

[0006] Preferably, the extension length of the telescopic rod is less than the extension length of the electric cylinder, and the extension length of the telescopic rod is greater than the depth of the mold cavity.

[0007] Preferably, the tilt angle of the support plate is 20° when both the telescopic rod and the electric cylinder are extended to their maximum length.

[0008] Preferably, one side of the mold cavity is provided with an inclined plate whose end is fixed to the bottom surface of the workbench, and the top surface of the inclined plate is on the same plane as the top surface of the support plate when it is tilted at 20°.

[0009] Preferably, while the bottom surface of the push plate is in contact with the top surface of the support plate, the side surface of the push plate is perpendicular to the top surface of the support plate.

[0010] Preferably, a fixed plate is fixed on the worktable, and a movable plate connected to a push plate is slidably arranged inside the fixed plate. The movable plate is provided with toothed grooves. A drive motor is installed on the worktable, and a turntable located inside the fixed plate and the movable plate is driven by a transmission rod at the output end of the drive motor. The turntable is provided with a number of fixed rods that mesh with the toothed grooves.

[0011] Preferably, the length of the push plate's movement on the top surface of the support plate is no more than one-fifth of the length of the push plate's reciprocating motion in a single stroke.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model uses a telescopic rod and an electric cylinder to push the support plate out of the mold cavity, thereby pushing the injection molded product on the support plate out of the mold cavity. The reciprocating push plate pushes the cooled injection molded product to separate the injection molded product from the support plate, thus completing the unloading work. The high degree of automation improves production efficiency.

[0014] 2. This utility model uses the different extension lengths of the telescopic rod and the electric cylinder to make the support plate tilt. The tilted support plate causes the push plate to separate the injection molded product from the support plate and slide down the support plate onto the inclined plate and then onto the worktable, thereby allowing the injection molding work to continue and further improving production efficiency.

[0023] It is readily understood that, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementations without altering the essential spirit of this utility model. Therefore, the following detailed embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as limitations or restrictions on the technical solution of this utility model.

[0024] like Figure 1 As shown, the auxiliary structure for blanking injection molds of hydraulic equipment components of this utility model includes a U-shaped worktable 1. A mold cavity 2 is fixed on the bottom surface of the worktable 1. A hydraulic cylinder 4 is installed on the top of the worktable 1. The output end of the hydraulic cylinder 4 is driven by a template 3 located above the worktable 1 and corresponding to the mold cavity 2, ensuring the stable operation of the injection molding process. Telescopic rods 8 and electric cylinders 9 are respectively provided on both sides of the bottom of the worktable 1. The top of the telescopic rods 8 and the electric cylinders 9 is movably provided with the same support plate 7 located in the mold cavity 2 and slidably connected to the mold cavity 2. The support plate 7 is pushed out of the mold cavity 2 by the telescopic rods 8 and the electric cylinders 9, thereby pushing the injection molded product on the support plate 7 out of the mold cavity 2, which is beneficial to the blanking process.

[0025] A fixing plate 11 is fixed on the workbench 1, such as Figure 4 As shown, a movable plate 5 is slidably disposed inside the fixed plate 11. A push plate 15 is fixed to the end of the movable plate 5. The movable plate 5 is provided with a toothed groove 14. A drive motor 10 is installed on the worktable 1. The output end of the drive motor 10 is driven by a transmission rod to a turntable 12 located inside the fixed plate 11 and the movable plate 5. The turntable 12 is provided with several fixed rods 13 that mesh with the toothed groove 14. The drive motor 10 drives the turntable 12 to rotate, thereby driving the movable plate 5 to reciprocate within the fixed plate 11. The reciprocating motion of the movable plate 5 drives the push plate 15 to reciprocate, thereby separating the injection molded product on the support plate 7 from the support plate 7, thus completing the unloading operation.

[0026] like Figure 3 As shown, the extension length of the telescopic rod 8 is less than the extension length of the electric cylinder 9, and the extension length of the telescopic rod 8 is greater than the depth of the mold cavity 2. The difference in extension length between the telescopic rod 8 and the electric cylinder 9 causes the support plate 7 to tilt. This tilted support plate 7 causes the push plate 15 to separate the injection molded product from the support plate 7 and then slide down along the support plate 7. Figure 2As shown, when both the telescopic rod 8 and the electric cylinder 9 are extended to their maximum length, the tilt angle of the support plate 7 is 20°. A sloping plate 6 with its end fixed to the bottom surface of the worktable 1 is provided on one side of the mold cavity 2. The top surface of the sloping plate 6 and the top surface of the support plate 7 when tilted at 20° are located on the same plane, ensuring the smooth sliding of the injection molded product. At the same time, the injection molded product slides from the support plate 7 to the sloping plate 6 and then to the worktable 1 without the need for separate collection of the injection molded product from the support plate 7. This allows the injection molding work to continue and further improves production efficiency.

[0027] When the telescopic rod 8 and the electric cylinder 9 are extended to their maximum length, the bottom surface of the push plate 15 is always in contact with the top surface or the extended surface of the top surface of the support plate 7, ensuring that the push is made from the bottom of the injection molded product. This is beneficial to the stability of the material feeding operation. In addition, the side of the push plate 15 is perpendicular to the top surface of the support plate 7, so that the push plate 15 and the injection molded product are also in surface contact, thereby increasing the contact area, reducing the pressure generated during dragging, and thus preventing the injection molded product from deforming.

[0028] The length of the push plate 15 moving on the top surface of the support plate 7 is no more than one-fifth of the single-stroke length of the push plate 15 reciprocating motion, so that the push plate 15 is located far away from the support plate 7 most of the time, thus ensuring the stability of the template 3 descending. At the same time, the push plate 15 completes one injection molding operation by reciprocating once.

[0029] During use, the injection molding process is completed by lowering the template 3. After the injection molding is completed, the template 3 is reset, and the electric cylinder 9 drives the support plate 7 to rise to its maximum height. At this time, the support plate 7 tilts. After the injection molded product on the support plate 7 cools down, the push plate 15 moves to one end of the support plate 7 and continues to move, thereby separating the injection molded product on the support plate 7 from the support plate 7. The separated injection molded product slides down the support plate 7 and the inclined plate 6 onto the worktable 1. During this process, the push plate 15 begins to return to the mold cavity 2. After the mold cavity 2 can descend, it descends to carry out the next injection molding operation.

[0030] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
