Description

Technical Field

[0001] This utility model belongs to the field of golf ball production technology, specifically a golf ball skin injection molding equipment. Background Art

[0002] Golf ball injection molding equipment is a key piece of equipment used to manufacture golf ball shells. It generally includes an upper mold and a lower mold, each with a corresponding hemispherical cavity. When the upper and lower molds come into contact, the two hemispherical cavities form a complete spherical cavity. Before injection molding, the ball core is loaded into the hemispherical cavity of the lower mold, and then injection molding is performed. After curing, the production of the golf ball is complete. Then, after the upper mold moves upward and opens, the produced golf ball is unloaded. However, the following defects still exist:

[0003] The injection molding process needs to be divided into three steps: core loading, shell injection, and unloading. This makes the injection molding process unsustainable and results in low processing efficiency. Utility Model Content

[0004] In view of the above situation and to overcome the defects of the prior art, this utility model provides a golf ball skin injection molding equipment, which effectively solves the problem that the injection molding process cannot be carried out continuously, resulting in low processing efficiency.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a golf ball skin injection molding equipment, including a mounting frame, connecting plates symmetrically mounted on both sides of the mounting frame, a side plate fixedly mounted on one end of the connecting plate, a support frame mounted on the side of the side plate away from the mounting frame, a fixing frame fixedly mounted on one of the support frames, an upper mold assembly mounted on the fixing frame, and a lower mold assembly provided on the outer side of the mounting frame;

[0006] The lower mold assembly includes eight lower molds evenly distributed on the outside of the mounting frame. A fixing block is fixedly installed on the side of the lower mold closest to the mounting frame. Fixing rods are fixedly installed on both sides of the fixing block. Two synchronous belts are symmetrically provided at both ends of the fixing rods. The synchronous belts are fixedly connected to the fixing rods on the same side of each fixing block.

[0007] Preferably, the inner side of the synchronous belt is symmetrically provided with two pulleys, which are a driving pulley and a driven pulley, respectively. A rotating shaft is coaxially fixed between the driving pulleys on both sides and between the driven pulleys on both sides. The rotating shaft is rotatably connected to the side plate. One end of the rotating shaft on the driving pulley is fixedly connected to the output shaft of the motor. The motor is fixedly mounted on the side plate.

[0008] Preferably, the lower mold has a hemispherical cavity evenly formed on the side away from the mounting frame, and protrusions are evenly installed on the inner wall of the hemispherical cavity.

[0009] Preferably, a roller is installed on the side of the fixing block near the mounting frame, and the roller contacts the outer wall of the mounting frame.

[0010] Preferably, the upper mold assembly includes an upper mold located below the fixed frame. The bottom end of the upper mold is also uniformly provided with hemispherical cavities. The top end of the upper mold is uniformly installed with feed pipes, which correspond one-to-one with the hemispherical cavities. The feed pipes are used to input injection liquid. The top end of the upper mold is fixedly connected to the output ends of two cylinders, which are fixedly installed on the fixed frame.

[0011] Preferably, the upper mold is located above the mounting frame. When the upper mold is directly above the lower mold, the hemispherical cavity on the upper mold corresponds one-to-one with the hemispherical cavity on the lower mold. At this time, there are three lower molds above the mounting frame, which are used for feeding the ball core, injecting the ball skin, and unloading the ball, respectively.

[0012] Compared with the prior art, the beneficial effects of the present invention are:

[0013] During operation, three lower molds are always present above the mounting frame. One of the lower molds is located directly below the upper mold for injection molding. One lower mold feeds the ball core, while the other lower mold unloads the finished ball, allowing the injection molding production of the ball skin to continue and improving the production efficiency of golf balls.

[0014] During operation, the fixing rods on both sides of the bottom fixing block of the lower mold are fixedly connected to two synchronous belts respectively. At the same time, the rollers on the side of the fixing block near the mounting frame contact the outer wall of the mounting frame, which improves the movement stability of the lower mold. In addition, it can generate an upward supporting force on the lower mold during injection molding, thereby improving the injection molding stability. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present utility model without creative effort are within the protection scope of the present utility model.

[0023] Embodiment 1, by Figure 1-4 The present invention relates to a golf ball skin injection molding equipment, including a mounting frame 1, connecting plates 2 symmetrically mounted on both sides of the mounting frame 1, a side plate 3 fixedly mounted on one end of the connecting plate 2, a support frame 4 mounted on the side of the side plate 3 away from the mounting frame 1, a fixing frame 5 fixedly mounted on one of the support frames 4, an upper mold assembly 6 mounted on the fixing frame 5, and a lower mold assembly 7 provided on the outer side of the mounting frame 1;

[0024] The lower mold assembly 7 includes eight lower molds 704 evenly distributed on the outside of the mounting frame 1. A fixing block 705 is fixedly installed on the side of each lower mold 704 closest to the mounting frame 1. Fixing rods 706 are fixedly installed on both sides of each fixing block 705. Two synchronous belts 703 are symmetrically arranged at both ends of each fixing rod 706. The synchronous belts 703 are fixedly connected to the fixing rods 706 on the same side of each fixing block 705. Two pulleys 701 are symmetrically arranged on the inner side of each synchronous belt 703, serving as a driving pulley and a driven pulley, respectively. Rotating shafts are coaxially fixedly installed between the driving pulleys on both sides and between the driven pulleys on both sides. The rotating shafts are rotatably connected to the side plate 3. One end of the rotating shaft on the driving pulley is fixedly connected to the output shaft of a motor 702. The motor 702 is fixedly installed on the side plate 3. A hemispherical cavity 708 is evenly formed on the side of the lower mold 704 away from the mounting frame 1. The inner wall of the hemispherical cavity 708... The upper part is evenly equipped with protrusions 709. A rolling wheel is installed on the side of the fixing block 705 near the mounting frame 1. The rolling wheel contacts the outer wall of the mounting frame 1. Three lower molds 704 are always present above the mounting frame 1. One of the lower molds 704 is located directly below the upper mold 601 and is used for injection molding. One lower mold 704 feeds the ball core, and the other lower mold 704 unloads the finished injection molded golf ball, so that the injection molding production of the ball skin can continue and improve the production efficiency of golf balls. The fixing rods 706 on both sides of the fixing block 705 at the bottom of the lower mold 704 are fixedly connected to two synchronous belts 703 respectively. At the same time, the roller on the side of the fixing block 705 near the mounting frame 1 contacts the outer wall of the mounting frame 1, which improves the movement stability of the lower mold 704. At the same time, it can generate an upward supporting force on the lower mold 704 during injection molding, which improves the injection molding stability.

[0025] The upper mold assembly 6 includes an upper mold 601 located below the fixed frame 5. The bottom end of the upper mold 601 is also uniformly provided with hemispherical cavities 708. The top end of the upper mold 601 is uniformly installed with feed pipes 602, which correspond one-to-one with the hemispherical cavities 708. The feed pipes 602 are used to input injection liquid. The top end of the upper mold 601 is fixedly connected to the output ends of two cylinders 603. The cylinders 603 are fixedly installed on the fixed frame 5. The upper mold 601 is located above the mounting frame 1. When the upper mold 601 is located directly above the lower mold 704, the hemispherical cavities 708 on the upper mold 601 correspond one-to-one with the hemispherical cavities 708 on the lower mold 704. At this time, there are three lower molds 704 above the mounting frame 1. The three lower molds 704 are used for ball core feeding, ball skin injection molding, and ball unloading, respectively.

[0026] Working principle: During operation, the motor 702 is first turned on, which drives the pulley 701, which is the driving wheel, to rotate. This drives the synchronous belt 703 to rotate. Each time the motor is turned on, it moves one of the lower molds 704 to directly below the upper mold 601. Each hemispherical cavity 708 on the lower mold 704 contains a ball core. Then, the cylinder 603 is turned on, causing the upper mold 601 to move downward until it is in close contact with the lower mold 704. This forms a spherical cavity with the hemispherical cavities 708 on the upper mold 601 and the lower mold 704. The ball core is located inside the spherical cavity. Then, the injection molding liquid is introduced into the spherical cavity through the feed pipe 602. After solidification, the injection molding liquid forms a spherical skin on the outside of the ball core, completing the processing. The protrusions 709 on the inner wall of the hemispherical cavity 708 create pits on the outside of the spherical skin.

[0027] During injection molding, three lower molds 704 are always present above the mounting frame 1. One of the lower molds 704 is located directly below the upper mold 601 and is used for injection molding. One lower mold 704 is used for feeding the ball core, and the other lower mold 704 is used for unloading the completed injection molded golf ball.

[0028] During the movement of the lower mold 704, the fixing rods 706 on both sides of the fixing block 705 at the bottom of the lower mold 704 are fixedly connected to the two synchronous belts 703 respectively, and the rollers on the side of the fixing block 705 near the mounting frame 1 are in contact with the outer wall of the mounting frame 1, thereby improving the movement stability of the lower mold 704.
