Description

Technical Field

[0001] This utility model relates to the field of press-fitting equipment technology, specifically a mold press-fitting machine. Background Technology

[0002] Press fitting machines are widely used pressure processing equipment in fields such as machinery manufacturing, automotive parts processing, and electronic component assembly. They are mainly used for processes such as pressing, stamping, riveting, and forming of workpieces. Traditional press fitting machines typically include core components such as a frame, hydraulic or mechanical drive system, worktable, and press fitting head, and complete the processing of workpieces by applying controllable pressure.

[0003] In existing technologies, the worktable of press fitting machines typically adopts a fixed structure or only supports mold installation and adjustment within a limited range. Although it can meet basic assembly requirements, when dealing with molds of different sizes, shapes, or installation requirements, it is often necessary to frequently change fixtures or adjust the positioning mechanism, resulting in reduced production efficiency. Utility Model Content

[0005] To achieve the above objectives, this utility model provides the following technical solution: a mold pressing machine, including a frame, wherein a positioning platform for positioning molds of different sizes is provided on the frame; the positioning platform includes: a body, disposed on the frame; a plurality of T-shaped positioning grooves, disposed on the body, each T-shaped positioning groove including a first groove segment and a second groove segment extending along the depth direction of the first groove segment, the width of the second groove segment being greater than the width of the first groove segment, and each T-shaped positioning groove having at least one open end; and a positioning element used in conjunction with the T-shaped positioning groove, disposed in the T-shaped positioning groove.

[0006] Preferably, the positioning element includes: a reverse-threaded double-ended stud disposed in the T-shaped positioning groove; a first threaded component and a second threaded component respectively disposed on the threads at both ends of the reverse-threaded double-ended stud; and a contact assembly disposed on the second threaded component for positioning the mold. Preferably, the contact assembly includes: a rotating member disposed on the second threaded member and coaxially arranged therewith; and a contact plate disposed on the rotating member.

[0007] Preferably, the opposing surfaces of the first threaded component and the second threaded component are provided with rubber sheets to increase frictional resistance.

[0008] Preferably, the end of the reverse-threaded double-ended stud is provided with a hexagonal extension.

[0009] Compared with the prior art, the beneficial effects of this utility model are: By creating two T-shaped positioning grooves with the same magnified reference point on the positioning table body, and using positioning components that can slide along the inner wall of the groove, adaptive clamping of molds of different sizes is achieved. At the same time, the reverse-threaded double-ended stud and the opposing-rotation threaded components work together to achieve synchronous clamping in unidirectional rotation. The rubber sheet increases frictional damping to prevent loosening, and the hexagonal extension simplifies wrench operation and shortens mold change time. Overall, the positioning accuracy, clamping reliability and production efficiency of the press machine are improved. Attached Figure Description

[0016] Example Please see Figure 1-5 As shown, the present invention provides a mold pressing machine technical solution: a mold pressing machine, including a frame 1, on which a positioning table 2 for positioning molds of different sizes is provided; The positioning table 2 includes: a body 201, several sets of T-shaped positioning grooves 202, and positioning elements 203 that cooperate with the T-shaped positioning grooves 202. The body 201 is mounted on the frame 1, and the T-shaped positioning grooves 202 are mounted on the body 201. The T-shaped positioning grooves 202 include a first groove segment 2021 and a second groove segment 2022 extending along the depth direction of the first groove segment 2021. The width of the second groove segment 2022 is greater than the width of the first groove segment 2021. Each T-shaped positioning groove 202 has at least one open end 2023, and the positioning element 203 is disposed in the T-shaped positioning groove 202.

[0017] In this embodiment, the first groove segment 2021 and the second groove segment 2022 share the same geometric base point, which is enlarged proportionally to form the latter. The opening end 2023 is located at the edge of the body 201, which facilitates the entry and exit of the positioning member 203.

[0018] The positioning component 203 includes: a reverse-threaded double-ended stud 2031, a first threaded component 2032 and a second threaded component 2033, and a contact component 3. The reverse-threaded double-ended stud 2031 is detachably disposed in the T-shaped positioning groove 202. The first threaded component 2032 and the second threaded component 2033 are respectively disposed on the threads at both ends of the reverse-threaded double-ended stud 2031. The contact component 3 is disposed on the second threaded component 2033 and is used to position the mold.

[0019] In this embodiment, the first threaded component 2032 and the second threaded component 2033 have the same structure, and both of them have internal threads that match the external threads at both ends of the reverse-threaded double-ended stud 2031.

[0020] The contact assembly 3 includes a rotating member 301 and a contact plate 302. The rotating member 301 is disposed on the second threaded member 2033 and is coaxially disposed therewith. The contact plate 302 is disposed on the rotating member 301.

[0021] In this embodiment, the rotating component 301 can be designed as a bearing coaxially sleeved on the outer wall of the second threaded component 2033, and the contact plate 302 is fixed to the side wall of the rotating component 301 by a connecting rod.

[0022] The first threaded component 2032 and the second threaded component 2033 have rubber sheets 4 on their opposing surfaces to increase frictional resistance.

[0023] The end of the reverse-threaded double-ended stud 2031 is provided with a hexagonal extension 5, which is used to disassemble or tighten with a wrench or other accessories.

[0024] The working principle of this utility model is as follows: When a new mold needs to be positioned, the operator first places the mold roughly in the center of the workbench, and then pushes the rotating part 301 of each positioning component 203 into the open end 2023 of the T-shaped positioning groove 202. At this time, the first threaded part 2032 enters the widened second groove section 2022, while the second threaded part 2033 remains outside the groove and abuts against the edge of the mold, with the contact plate 302 tightly against the side wall of the mold. After all positioning components 203 are in place, each rotating part 301 is tightened in sequence. During the tightening process, the end face of the first threaded part 2032 presses against the groove wall of the first groove section 2021 to generate friction, while the operator must prevent the second threaded part 2033 from moving, so that the first threaded part 2032 and the second threaded part 2033 move in opposite directions and together clamp the narrow opening of the first groove section 2021, thereby reliably fixing the mold. To release the positioning, simply rotate the reverse-threaded double-ended stud 2031 in the opposite direction, and the positioning component 203 will loosen, allowing the mold to be removed, thus achieving quick mold change.

[0025] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
