Technical Field

[0001] This utility model relates to the field of metal parts processing technology, specifically to a forming mold for metal parts processing. Background Technology

[0002] Metalworking, or metal processing for short, refers to the production activities of humans processing materials with metallic properties, which are composed mainly of metallic elements. It is a craft technology that processes metal materials into items, parts, and components, including large parts such as bridges and ships, as well as small components such as engines, jewelry, and watches. It is widely used in various fields such as science, industry, art, and handicrafts. When processing metal parts, forming molds are used. Forming molds, also known as dies, are molds made according to the shape and structure of the actual object in proportion.

Detailed Implementation

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] This utility model provides, for example Figures 1-5 The mold shown is a forming mold for processing metal parts, including a base 1, a lower mold 2 mounted on the base 1, a moving mechanism 3 at the bottom of the base 1, a lifting plate 4 fixedly connected to the moving mechanism 3, a push rod 5 fixedly connected to the top of the lifting plate 4, the top of the push rod 5 penetrating into the mold cavity of the lower mold 2, a support assembly 6 fixedly connected around the top of the base 1, a hydraulic cylinder 7 mounted on the top of the support assembly 6, a moving seat 8 used in conjunction with the support assembly 6 fixedly connected to the piston rod of the hydraulic cylinder 7, an upper mold 9 mounted on the lower surface of the moving seat 8, and an injection tube 10 used in conjunction with the upper mold 9 embedded in the moving seat 8. The moving mechanism 3 can quickly drive the push rod 5 on the lifting plate 4 to quickly demold the metal parts formed in the mold cavity of the lower mold 2, improving the demolding speed of the metal parts and enhancing the working efficiency of the forming mold for processing metal parts.

[0024] The moving mechanism 3 includes a lead screw 31 and a double-headed motor 32. The output shaft of the double-headed motor 32 is fixedly connected to one end of the lead screw 31, and the other end of the lead screw 31 is rotatably connected to the inner wall of the base 1 through a bearing. A moving plate 34 is threadedly connected to the lead screw 31 through a threaded sleeve 33. Limiting components 35, which are fixedly connected to the inner wall of the base 1, are provided at both ends of the moving plate 34. A first movable seat 36 is fixedly connected to the center of the top of the moving plate 34. A movable rod 37 is movably connected to the inner cavity of the first movable seat 36. A second movable seat 38 is movably connected to the other end of the movable rod 37. The top of the second movable seat 38 is connected to the bottom of the lifting plate 4. The parts are fixedly connected, and the dual-head motor 32 can drive two lead screws 31 to rotate simultaneously. Then, the threaded sleeve 33 on the lead screw 31 drives the moving plate 34 to move. While the moving plate 34 is moving, the limiting component 35 provides a limiting effect on the moving plate 34 to prevent the moving plate 34 from rotating synchronously with the lead screw 31. The moving plate 34 drives the moving rod 37 to adjust its height through the first movable seat 36. In turn, the moving rod 37 drives the push rod 5 on the lifting plate 4 to adjust its height through the second movable seat 38. Therefore, the metal parts formed in the mold cavity of the lower mold 2 can be quickly demolded through the push rod 5.

[0025] The limiting component 35 includes a limiting sleeve 351, which is embedded at both ends of the moving plate 34. The inner cavity of the limiting sleeve 351 is slidably connected to a limiting rod 352, and the two ends of the limiting rod 352 are fixed to the inner wall of the base 1. The cooperation between the limiting sleeve 351 and the limiting rod 352 can provide a limiting effect on the moving plate 34 and prevent the moving plate 34 from rotating.

[0026] The support assembly 6 includes four support rods 61, which are fixed around the top of the base 1. The upper end of the support rods 61 is fixedly connected to the mounting plate 62. The hydraulic cylinder 7 is mounted on the mounting plate 62. The movable seat 8 is fitted with sliding sleeves 63 that cooperate with the support rods 61. By setting the cooperation between the support rods 61 and the mounting plate 62 in the support assembly 6, the upper mold 9 on the movable seat 8 can be quickly and directly docked with the lower mold 2 under the drive of the hydraulic cylinder 7, thereby improving the positioning effect between the upper mold 9 and the lower mold 2, making the metal parts formed between the upper mold 9 and the lower mold 2 less prone to deformation, and improving the quality of metal parts forming.

[0027] A spring 11 is sleeved on the lower surface of the support rod 61. The top end of the spring 11 is fixed on the movable seat 8, and the lower end of the spring 11 is fixed on the base 1. The spring 11 can provide a buffering effect on the impact force between the upper mold 9 and the lower mold 2.

[0028] A fixing rod 12 is fixedly connected to the upper surface of the movable seat 8 at a symmetrical position. A rubber pad 13 that fits against the lower surface of the mounting plate 62 is fixedly connected to the top of the fixing rod 12. The cooperation between the fixing rod 12 and the rubber pad 13 can provide support for the hydraulic air to drive the movable seat 8 to move upward, preventing the movable seat 8 from fitting against the mounting plate 62. This creates a space between the movable seat 8 and the mounting plate 62, which facilitates the installation and use of the injection tube 10.

[0029] Each injection tube 10 is equipped with a flow control valve 14. The end of the injection tube 10 near the lower mold 2 is kept horizontal with the surface of the lower mold 2. By setting the flow control valve 14, the flow of the metal liquid flowing in the injection tube 10 can be controlled to avoid too much or too little metal liquid being added, which would affect the molding effect of the metal parts.

[0030] In practical use, the hydraulic cylinder 7 first drives the movable seat 8 on the support rod 61 to move to a limited position. Then, the movable seat 8 drives the upper mold 9 to quickly dock with the lower mold 2, improving the positioning effect between the upper mold 9 and the lower mold 2, making the metal parts formed between the upper mold 9 and the lower mold 2 less prone to deformation. Then, the molten metal is introduced into the mold cavity of the lower mold 2 through the metal injection tube 10, and cooperates with the upper mold 9 to perform injection molding of the metal parts. After molding, the metal parts are driven by the dual-head motor 32 to drive the two lead screws 31 to rotate simultaneously. Then, the lead screws 31 are driven by the... The threaded sleeve 33 drives the moving plate 34 to move. While the moving plate 34 moves, the limiting component 35 provides a limiting effect on the moving plate 34 to prevent the moving plate 34 from rotating synchronously with the lead screw 31. The moving plate 34 drives the moving rod 37 to adjust its height through the first movable seat 36. Thus, the moving rod 37 drives the push rod 5 on the lifting plate 4 to adjust its height through the second movable seat 38. Therefore, the metal parts formed in the lower mold cavity can be quickly demolded through the push rod 5, which improves the demolding speed of the metal parts and enhances the working efficiency of the forming mold for processing metal parts.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
