DETAILED DESCRIPTION

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0030] See also Figure 1-Figure 6The utility model provides a technical solution: a flat cable extruder head, comprising a head body 1 provided with a feed port 2, the feed port 2 is connected to a working cabin 3, and the working cabin 3 is detachably connected to a mold 4, and the extrusion end of the head body 1 is rotatably provided with at least one end cap 5. In this embodiment, two end caps 5 are selected, and the end caps 5 are symmetrically arranged about the head body 1. Specifically, the flat cable extruder head comprises: a rotating shaft 6, which is arranged on one side of the end cap 5; a fixing seat 7, which is arranged on one side of the head body 1, and the rotating shaft 6 is connected to a rotating hole opened on the surface of the fixing seat 7;

[0031] The above technical solution can be used to conveniently open the end cover 5 so as to replace the mold 4 inside the head body 1 .

[0032] like Figure 2 As shown, the flat cable extruder head also includes a driving assembly for controlling the opening and closing of the end cover 5. Specifically, the driving assembly includes an electric push rod 9 arranged on the side of the head body 1. The electric push rod 9 is connected to the head body 1 through a rod seat 8, and its output end is connected to a hinge 10, and the hinge 10 is connected to the end cover 5;

[0033] The above technical solution can realize automatic opening of the end cover 5. When the mold 4 needs to be removed, the electric push rod 9 is started to retract, and the electric push rod 9 drives the hinge 10 to move, thereby driving the end cover 5 to open. When the end cover 5 is opened, the limit on the mold 4 is released.

[0034] like Figure 3 and Figure 4 As shown, the flat cable extruder head also includes at least two guide components arranged relative to the mold 4, and the guide components include: a fixed plate 11, which is arranged on the inner wall of the head body 1; a guide rod 12, one end of which is fixed to the fixed plate 11; a movable plate 13, which is arranged on the side of the mold 4, and the guide rod 12 is slidably matched with a guide groove 14 opened on the surface of the movable plate 13;

[0035] like Figure 4 As shown, the flat cable extruder head also includes an elastic member, which is arranged between the fixed plate 11 and the movable plate 13 to give the movable plate 13 an elastic force so that the extrusion port of the mold 4 extends out of the outlet 19 opened on the surface of the end cover 5; specifically, the elastic member includes a first spring 15, one end of which is connected to the fixed plate 11, and the other end of the first spring 15 is in contact with the movable plate 13;

[0036] The above technical solution can realize the ejection of the mold 4 while opening the end cover 5. When the end cover 5 is opened, the limit on the mold 4 is released. Under the elastic force of the first spring 15, the movable plate 13 slides along the guide rod 12, thereby driving the mold 4 to slide out of the head body 1.

[0037] Further, such as Figure 6As shown, the flat cable extruder head also includes an elastic limiting component, which is arranged at one end of the guide rod 12 close to the end cover 5 to limit the movable plate 13, and the elastic limiting component includes: a convex plate 17, which is movably arranged in an inner groove 16 opened in the guide rod 12; a second spring 18, one end of which is connected to the inner groove 16, and the other end of the second spring 18 abuts against the bottom of the convex plate 17; the surface of the convex plate 17 is provided with anti-slip grooves to increase the friction coefficient between the convex plate 17 and the guide groove 14;

[0038] The above technical solution can prevent the mold 4 from falling and being damaged. When the movable plate 13 slides to the end of the guide rod 12, the guide groove 14 inside the movable plate 13 contacts the convex plate 17. Since the convex plate 17 is connected to the second spring 18, the second spring 18 can exert elastic force on the convex plate 17, so that the convex plate 17 exerts pressure on the inner wall of the guide groove 14, thereby fixing the movable plate 13 and preventing the movable plate 13 from completely sliding out of the guide rod 12 and causing the mold 4 to fall. The mold 4 can be disassembled by holding it and slowly driving it to separate from the guide rod 12.

[0039] Working principle: when the mold 4 needs to be disassembled, the electric push rod 9 is started to retract, and the electric push rod 9 drives the hinge 10 to move, thereby driving the end cover 5 to open. When the end cover 5 is opened, the limit on the mold 4 is released. Under the elastic force of the first spring 15, the movable plate 13 slides along the guide rod 12, thereby driving the mold 4 to slide out of the head body 1. When the movable plate 13 slides to the end of the guide rod 12, the guide groove 14 inside the movable plate 13 contacts the convex plate 17. Since the convex plate 17 is connected to the second spring 18, the second spring 18 can apply elastic force to the convex plate 17, so that the convex plate 17 presses the inner wall of the guide groove 14, which plays a role in fixing the movable plate 13, preventing the movable plate 13 from completely sliding out of the guide rod 12 and causing the mold 4 to fall off. The mold 4 can be held by hand and slowly driven to separate it from the guide rod 12 to complete the disassembly, which is very convenient.
