DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1 As shown, the existing product is a clip-type plastic wire fixing bracket, which realizes deformation through plastic elasticity, realizes the change of the clamp size through elastic deformation, and achieves the purpose of fixing through clamping force. Usually, three or more wires are connected to it. In the production process, it is necessary to connect the wires to the fixing bracket. Since the fixing bracket is produced by a mold injection molding process, the wires are injection molded onto the fixing bracket. The traditional injection molding process is easy to form a gate material. Therefore, this embodiment proposes the following wire harness fixing bracket mold and provides a corresponding molding process.

[0040] like Figure 2 As shown, the wire harness fixing mold of this embodiment adopts the same mold form as most injection molding processes, that is, the upper and lower molds are combined for injection molding. Therefore, this mold includes an upper mold 2 and a lower mold 1, which can reduce the research and development cost of the wire harness fixing frame mold and is also convenient for factories to promote and use.

[0041] like Figure 3 As shown, the lower mold 1 in the present mold includes a base plate 3, a panel 4, a mold core seat 5 and an injection molding seat 6 from bottom to top, wherein the mold core seat 5 in the lower mold 1 is a fixing frame molding part, the mold core seat 5 is installed on the panel 4, the injection molding seat 6 is installed in the middle of the panel 4, two mold core seats 5 are provided and are respectively located on both sides of the injection molding seat 6, the base plate 3 is installed at the bottom of the panel 4, the fixing frame molding requires the mold core seat 5 and the injection molding seat 6 to cooperate, and limiting members 7 are also installed on both sides of the top of the panel 4. The limiting members 7 are used to limit the wiring harness to ensure the stable position of the wiring harness during the injection molding process of the fixing frame.

[0042] Specifically, Figure 4 Schematic diagram of the exploded structure of the lower mold 1. It can be seen from the figure that the mold core seat 5 is symmetrically provided with two mold cavities 501. Therefore, the mold is provided with at least two stations, each of which is respectively operated to form two wire harness fixing frames. The two ends of the limiter 7 are bent, and two plug holes 403 are respectively provided on both sides of the top of the panel 4. The two ends of the limiter 7 are bent toward the plug holes 403. The limiter 7 is inserted into the plug holes 403. A wire groove 401 is provided on both sides of the top of the panel 4, and the two ends of each mold core seat 5 are the same. A wire groove 1 502 corresponding to the position of the wire groove 2 401 is also provided, and the wire groove 1 502 and the wire groove 2 401 form a channel for placing the wire harness, and a wire groove 3 701 is also provided at the bottom of both ends of the limiting member 7, and the wire groove 3 701 is connected with the wire groove 2 401 to form a circular channel. When the injection molding process is performed, the wire harness is placed in the circular channel formed by the wire groove 2 401 and the wire groove 3 701, and the limiting member 7 is used to press the wire harness to prevent the wire harness from detaching and limit it. The formation of the circular channel avoids the damage of the wire harness.

[0043] from Figure 1It can be seen that the two sides of the clamping arm of the wiring harness fixing frame are flat. In the design process of this mold, the core mold seat 5 is attached to the injection molding seat 6, and the one side plane of the injection molding seat 6 cooperates with the mold cavity 501 to form a molding chamber in the shape of the wiring harness fixing frame. Seats 402 are provided at both ends of the panel 4, and the core mold seat 5 is installed at the seat 402. The middle part of the panel 4 is through, and the injection molding seat 6 is located in the middle part of the panel 4. The injection molding seat 6 is set to be able to slide up and down in the middle part of the panel 4. Therefore, this embodiment has the following effects: the mold cavity 5 corresponds to the two sides of the injection molding seat 6. 01 are all provided with injection cylinders 9, and the mold directly fills the mold cavity 501 with raw materials through the injection cylinder 9. When the filling is completed, the injection seat 6 moves vertically downward, and the injection cylinder 9 is displaced out of the mold cavity 501. In this case, the injection cylinder 9 can no longer inject into the mold cavity 501, and the two sides of the wiring harness fixing frame are flat. Therefore, after the injection seat 6 moves downward, the flat surfaces on both sides can still form a complete fixing frame molding cavity with the mold cavity 501, and in this case, the formation of gate material can be directly avoided. (Gate material is the excess part formed after the plastic melt enters the mold cavity through the gate during the injection molding process and cools and solidifies at the gate. The gate material usually needs to be removed in the subsequent processing process, such as trimming, polishing, etc.).

[0044] like Figure 5 As shown, Figure 5 for Figure 4Schematic diagram of the cross-sectional structure at the center line L, side grooves 606 are provided on both sides of the injection molding seat 6 corresponding to the mold cavity 501, a clamping plate 602 is fixed at the top of the side groove 606 by screws 603, a spring plate 604 is fixed in the middle of the clamping plate 602, the middle of the spring plate 604 is bent toward the mold cavity 501, and a spring 2 605 is fixed between the bending part and the inner wall of one side of the side groove 606, the spring 2 605 gives a certain outward force to the spring plate 604, and the spring plate 604 is elastic as a whole. Under normal conditions, the spring plate 604 is attached to one side of the mold core seat 5 and does not contact the inside of the mold cavity 501, and is squeezed by the mold core seat 5, It is received in the middle of the side groove 606, when the injection molding seat 6 moves upward until the side groove 606 moves to the mold cavity 501, the spring plate 604 is in contact with the formed solid The fixed frame contacts the mold cavity 501. At this time, the fixed frame in the mold cavity 501 has also been formed and can be separated from the mold cavity 501 under the action of external force. Therefore, in this case, when the spring plate 604 moves to the mold cavity 501, it can resist the already formed fixed frame and give the fixed frame an upward peeling force during the upward pulling process, thereby assisting the fixed frame to separate from the mold cavity 501, that is, after the mold realizes the molding of the fixed frame, the fixed frame can be automatically demolded, and the spring plate 604 is bent near the middle, and its bottom or end extends into the side groove 606 to form a bend. Therefore, when the injection molding seat 6 moves downward, due to the elastic properties of the spring plate 604 itself and the setting of the bending part, the spring plate 604 will shrink in the side groove 606 again due to the extrusion of the core seat 5, thereby achieving its automatic reset effect.

[0045] like Figure 5 As shown, an inner seat 8 is installed in the middle of the injection molding seat 6, and the inner seat 8 is connected to the injection molding tube 10, and the injection molding of the mold is realized with the inner seat 8 as the medium. It can be seen from the figure that the inner seat 8 is installed from the bottom of the injection molding seat 6, and a slurry hole 801 is opened in the center of the top of the inner seat 8, and a plurality of injection molding through holes 802 corresponding to the mold cavity 501 are extended from the slurry hole 801. The injection molding cylinder 9 passes through the injection molding seat 6 and connects with the injection molding through holes 802. The inner seat 8 is provided with a thread at the connection between the injection molding cylinder 9 and the injection molding through holes 802, and the end of the injection molding cylinder 9 is screwed to the thread. The grouting hole in the middle of the injection molding cylinder 9 is hexagonal, which is convenient for using a hexagonal wrench to twist the injection molding cylinder 9 for installation. Therefore, it can be seen from the above structure that the inner seat 8 and the injection molding cylinder 9 are both detachable structures, and the inner seat 8 is connected and installed with the injection molding seat 6 through the installation of the injection molding cylinder 9. In this way, the inner seat 8 and the injection molding cylinder 9 can be easily installed and removed, which is convenient for later maintenance.

[0046] like Figure 6 As shown, Figure 6 for Figure 4The schematic diagram of the cross-sectional structure at the center line D shows that a vertical cavity 607 connected to the slurry hole 801 is provided in the middle of the injection seat 6, a slide seat 1001 is slidably installed in the middle of the vertical cavity 607, and the top end of the injection tube 10 is fixed to the slide seat 1001, so that the continuity of slurry injection during the up and down movement of the injection seat 6 is achieved without disconnecting the connection with the raw material.

[0047] like Figure 6 and Figure 7 As shown, a "convex" connecting hole 601 is opened at the top of the injection molding seat 6, and the upper mold 2 includes a top plate 206, and a connecting rod 207 is fixed to the bottom of the top plate 206. The bottom end of the connecting rod 207 is a gasket, and the gasket is arranged in the connecting hole 601, thereby realizing an indirect connection between the injection molding seat 6 and the top plate 206, and the up and down displacement of the injection molding seat 6 can be achieved by the displacement of the top plate 206.

[0048] like Figure 7 As shown, the upper mold 2 also includes a top plate 201, and the bottom of the top plate 201 is stacked and fixed with a backing plate 1 202, a backing plate 203 and a pressing plate 204. The bottom of the pressing plate 204 is provided with a mold core 205 corresponding to the position of the mold cavity 501. When the upper mold 2 and the lower mold 1 are molded together, the mold core 205 cooperates with the mold cavity 501 to form a fixed frame, and the middle of the backing plate 1 202, the backing plate 203 and the pressing plate 204 are all provided with a notch to form a middle groove. 211, the top plate 206 slides in the middle groove 211 and uses the middle groove 211 as a limit, a cylinder 208 is installed in the middle of the top plate 201, the cylinder 208 is connected to the top plate 206 and controls the lifting and lowering of the top plate 206, and a cylinder 209 is set on the top of the top plate 201. The cylinder 209 is used to control the overall displacement of the upper mold 2. The cylinder 209 is installed on the outer frame of the mold, and its specific installation position is not repeated here.

[0049] In summary, if Figure 8 and Fig. 9 As shown, Figure 8 and Fig. 9The cross-section and split structure of the entire mold are as follows: the wiring harness is placed in the wire groove in sequence, the end of the wiring harness is located in the mold cavity 501, and the wiring harness is limited by the limiter 7. The bottom of the pressure plate 204 on both sides of the upper mold 2 is also provided with an adapter groove 210 to match the protrusion of the limiter 7. After the wiring harness is limited, the upper mold 2 and the lower mold 1 can be controlled by the cylinder 209, and then the mold cavity 501 is grouted. After the grouting is completed, the injection seat 6 is controlled to move downward and stop the grouting by the cylinder 1 208. It should be noted that a plurality of limit rods 301 are provided on the bottom plate 3, and a spring is provided on the limit rod 301. Spring 1 302, the bottom of the injection molding seat 6 is provided with a plurality of holes corresponding to the limiting rod 301 and sits on the spring 1 302. During the grouting process, the injection molding seat 6 remains stable due to the support of the spring 1 302. Although the injection molding seat 6 will be given an upward force during the grouting process, the injection molding seat 6 can maintain a stable position under the limitation of the connecting rod 207. After the injection molding seat 6 moves downward, the fixing frame is formed in the mold cavity 501. After forming, the upper mold 2 is moved upward as a whole through the cylinder 209. During the upward movement, the injection molding seat 6 is pulled upward, and the fixing frame is peeled off from the mold cavity 501 by the spring plate 604 during the pulling process, completing the production of the wiring harness fixing frame.

[0050] The specific molding process is as follows:

[0051] Step 1: Place the wire harness in the circular channel formed by wire slot 1 502, wire slot 2 401 and wire slot 3 701 in sequence;

[0052] Step 2: Open the second cylinder 209 to control the upper mold 2 and the lower mold 1 to fit together;

[0053] Step 3: injecting grout into the mold cavity 501 through the injection tube 10;

[0054] Step 4: After the grouting is completed, the cylinder 1 208 controls the injection seat 6 to move downward so that the injection cylinder 9 moves out of the mold cavity 501;

[0055] Step 5: After the fixing frame is cooled and formed, the upper mold 2 is moved upward by the cylinder 209, and during the upward movement, the wire harness fixing frame is peeled off from the mold cavity 501 by the spring plate 604, completing the molding of the fixing frame.

[0056] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is limited by the attached embodiments and their equivalents.
