Description

Technical Field

[0001] This utility model relates to the field of connector processing technology, specifically a connector gate cutting fixture. Background Technology

[0002] In the injection molding or die casting process of connectors, a gating system must be designed to fill the mold cavity with molten material. This system typically includes a main runner, branch runners, and a gate. The gate is a narrow channel connecting the gating system to the product cavity. After the part cools and solidifies, this connector needs to be separated from the part body, leaving one or more excess blank portions on the connector, known as "gates" or "sprues".

[0003] During gate removal, the connector is typically placed on a "locating post" used for connector positioning, so that the protrusion on the locating post connects with the connecting groove of the connector to achieve the positioning purpose. However, the protrusion often cannot be precisely aligned with the connecting groove, and a certain gap remains between them. During the cutting process, the cutting blade applies a certain pushing force to the gate of the connector, which can easily cause the connector to shift, resulting in low cutting accuracy, uneven cut, and residual material residue on the surface of the connector, thus affecting subsequent use. Utility Model Content

[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] Please see Figures 1 to 7 This utility model provides a fixture for cutting the gate of a connector, including a support platform 1 and a limiting post 6 connected to the support platform 1. The support platform 1 is connected to a liftable lifting plate 2, which is connected to the output end of a hydraulic cylinder or a pneumatic cylinder for driving the lifting plate 2 to perform lifting and lowering actions. The lifting plate 2 is connected to a cutting blade 5 for cutting the gate. The limiting post 6 is connected to a limiting mechanism for limiting the connector 7. The limiting mechanism includes two clamping blocks 12, a wedge block 14, two connecting rods 17, and two springs 18. The clamping blocks 12 are movably connected to the limiting post 6. The wedge block 14 is used to drive the two clamping blocks 12 away from each other. The connecting rod 17 is used to guide the clamping blocks 12. The springs 18 are used to drive the two clamping blocks 12 closer to each other. The lifting plate 2 is connected to a driving mechanism for driving the wedge block 14 to lift and lower.

[0024] When the connector 7 is in the positioning state, the descent of the lifting plate 2 synchronously drives the two cutting blades 5 to descend. The lower cutting blade 5 completes the cutting purpose, while the upper cutting blade 5 ensures that the gate does not leave any burrs, thus guaranteeing the cutting quality.

[0025] The top of the support platform 1 is connected to two guide columns 3, which are slidably connected to the lifting plate 2. The guide columns 3 play a good guiding role for the lifting plate 2, improving the stability of the lifting of the cutting blade 5.

[0026] There are two cutting blades 5, arranged vertically. Each cutting blade 5 is slidably connected to the lifting plate 2 and is connected to a positioning bolt 4 for positioning. Adjusting the positioning bolt 4 allows for loosening or repositioning of the cutting blade 5, facilitating blade position adjustment and ensuring controllable cutting position. Once the cutting blade 5 is in the appropriate position, rotating the positioning bolt 4 causes its bottom to press firmly against the cutting blade 5, thus locking and fixing it in place.

[0027] The positioning bolt 4 is threadedly connected to the lifting plate 2, and the bottom of the positioning bolt 4 is pressed against the cutting blade 5. A U-shaped plate 11 is connected between the two cutting blades 5, and operating the U-shaped plate 11 facilitates the synchronous adjustment of the positions of the two cutting blades 5. The bottom of the positioning bolt 4 is provided with a friction surface to increase the contact friction with the cutting blade 5 and to provide a good limiting and fixing effect on the cutting blade 5.

[0028] The limiting mechanism also includes four pressing surfaces 13, which are disposed on the pressing blocks 12. The pressing blocks 12 are slidably connected to the limiting post 6. The connector 7 is provided with two connecting grooves 15, and the connecting grooves 15 are provided with arc-shaped surfaces 21. When the two pressing blocks 12 move away from each other, the pressing surfaces 13 press against the arc-shaped surfaces 21 of the connecting grooves 15, which can effectively limit and fix the connector 7, improve the stability of the connector 7 installation, and facilitate subsequent gate cutting operations.

[0029] The two ends of the connecting rod 17 are slidably connected to the clamping blocks 12. The spring 18 is sleeved on the connecting rod 17, and the two ends of the spring 18 are connected to the two clamping blocks 12. When the wedge block 14 rises, the stretched spring 18 drives the two clamping blocks 12 to move closer to each other, causing the clamping surface 13 to separate from the arc surface 21. At this time, the connecting piece 7 is in a loosened state, which facilitates quick disassembly.

[0030] The driving mechanism includes a lifting rod 8, a connecting plate 9, a lifting column 10, a lifting cylinder 20, a guide block 16, and a second spring 19. The top of the lifting column 10 is connected to the wedge block 14, the guide block 16 is slidably connected inside the lifting column 10, and the second spring 19 is used to drive the guide block 16 to move upward. The two ends of the lifting column 10 are connected to the guide block 16 and the connecting plate 9, and the end of the connecting plate 9 is connected to the lifting rod 8. The lifting rod 8 passes through the support platform 1, and the top of the lifting rod 8 is connected to the lifting plate 2.

[0031] During the descent of the lifting plate 2, before the cutting action is performed, the lifting rod 8, connecting plate 9, lifting column 10, and guide block 16 are simultaneously lowered. Spring 19 is compressed, pushing the lifting cylinder 20 downwards, simultaneously lowering the wedge block 14. This causes the wedge block 14 to slide relative to the two clamping blocks 12, driving the two clamping blocks 12 away from each other, thus limiting and fixing the connecting piece 7. At this time, spring 19 provides sufficient downward pressure to the lifting cylinder 20. As the lifting plate 2 continues to descend, the cutting blade 5 cuts the gate. Spring 19 is further compressed, increasing the downward pulling force on the wedge block 14, further pressing the clamping block 12 against the connecting piece 7, further strengthening the stability of the connecting piece 7 and ensuring the accuracy of the gate cutting.

[0032] Spring 19 is fitted onto the lifting column 10, and both ends of spring 19 are connected to the guide block 16 and the lifting cylinder 20.

[0033] Working principle: Connector 7 is fitted onto limiting post 6, aligning clamping block 12 with connecting groove 15 of connector 7. Lifting plate 2 descends, simultaneously driving cutting blade 5 downwards, thus lowering lifting rod 8, connecting plate 9, lifting post 10, and guide block 16. Spring 19 is compressed, applying downward force to lifting cylinder 20, causing lifting cylinder 20 to pull wedge block 14 downwards. Wedge block 14 drives two clamping blocks 12 away from each other, spring 18 is stretched, and clamping block 12 presses against connecting groove 15, thus limiting and fixing connector 7. Cutting operation has not yet begun at this point. The lifting plate 2 then descends further, allowing the cutting blade 5 to cut the gate. Meanwhile, the lifting rod 8, connecting plate 9, lifting column 10, and guide block 16 descend further, compressing the spring 19. The lifting cylinder 20 applies an increased downward pull to the wedge block 14, further pressing the clamping block 12 against the connector 7, thus enhancing the stability of the connector 7 and ensuring the accuracy of the gate cutting. After cutting, the lifting plate 2 moves upward, simultaneously moving the lifting rod 8, connecting plate 9, lifting column 10, and guide block 16 upward. The guide block 16 drives the lifting cylinder 20 and wedge block 14 upward. The stretched spring 18 pulls the two clamping blocks 12 closer together, separating them from the connecting groove 15, quickly loosening the connector 7 for easy disassembly, before proceeding with the gate cutting operation for the next connector 7.
