Description

Technical Field

[0001] The utility model relates to the technical field of wiring harness plugs, in particular to a wiring harness plug mould. Background Art

[0002] A wiring harness plug is an electrical connection component used to establish a reliable electrical connection between a wiring harness and other electrical devices (such as appliances, sensors, controllers, etc.). It is the end part of the wiring harness and usually contains multiple pins or jacks to connect multiple wires to the corresponding devices.

[0003] Usually, when processing and producing wiring harness plugs, corresponding upper and lower molds are needed for processing and molding, but most molds have the following shortcomings:

[0004] In the existing method, it is difficult to clamp the upper and lower molds together during use, which results in a gap between the upper and lower molds. This causes defects in the molded plug product. In addition, during the molding process, raw materials are prone to seepage, which reduces the applicability.

[0005] In response to the above problems, the present utility model document proposes a wiring harness plug mold. Utility Model Content

[0006] The utility model provides a wiring harness plug mold, which solves the problem in the prior art that it is inconvenient to clamp and fix the upper mold and the lower mold when in use, so that a gap is easily formed between the upper mold and the lower mold, resulting in certain defects in the molded plug product. At the same time, during the molding process, raw materials are prone to seepage, which reduces the applicability.

[0007] The utility model provides the following technical solutions:

[0008] A wiring harness plug mold, comprising:

[0009] An upper mold and a lower mold, wherein the upper mold is arranged on the top of the lower mold, the top side of the upper mold is provided with four limiting holes, and the interiors of the upper mold and the lower mold are respectively provided with four through holes connected to the limiting holes;

[0010] A fastening mechanism is provided between the upper mold and the lower mold, and is used to clamp and fix the upper mold and the lower mold;

[0011] The molding mechanism is arranged on the upper mold and the lower mold for processing and molding the wiring harness plug.

[0012] In one possible design, the fastening mechanism includes four screw rods, a limit plate, a clamping block, a base, a threaded groove and a suction cup. Each of the screw rods is limited to pass through the inside of the through hole. The limit plate is fixedly arranged on the top of the screw rod and is used to limit and be connected to the inside of the limit hole. Each of the clamping blocks is threadedly connected to the outer wall of the screw rod and is used to clamp and fix the lower mold in the direction of the upper mold.

[0013] In a possible design, each of the bases is fixedly disposed on the top of the suction cup, and the threaded groove is opened on the top side of the base for threaded connection of the screw rod.

[0014] In one possible design, the molding mechanism includes a feed port, two modules, a connecting hole, an upper molding cavity, a lower molding cavity, a positioning block and a positioning groove. The two modules are both arranged on the top of the lower mold, the positioning block is fixedly arranged on the bottom side of the module, and the positioning groove is opened on the top side of the lower mold for the positioning block to limit the engagement.

[0015] In a possible design, the upper molding cavity and the lower molding cavity are respectively opened on the bottom side of the module and the top side of the lower mold, and the connecting hole is opened inside the module and communicates with the upper molding cavity and the lower molding cavity.

[0016] In a possible design, the feed port is opened on the top side of the upper mold, and a feed hole connected to the feed port and the connecting hole is opened inside the upper mold.

[0017] In a possible design, corresponding sealing gaskets are provided on the bottom sides of the upper mold and the lower mold, respectively.

[0018] In the present application, when in use, first, place the lower mold on the operating platform to ensure that it is stable and motionless. Then, place the two modules on the top of the lower mold, and ensure that the positioning block on the bottom side of the module is accurately inserted into the positioning groove on the top side of the lower mold to achieve precise positioning of the module. Then, set the upper mold on the top of the lower mold and the module, and ensure that the limiting holes of the upper mold are aligned with the through holes in the lower mold and the module. Next, pass the four screws through the through holes respectively, and make the top ends of the screws limitedly engage in the limiting holes. Then, thread the outer wall of each screw to connect the clamping block, and rotate the screw to move the clamping block downward until the clamping block is in close contact with the top of the lower mold, thereby achieving clamping and fixing between the upper mold and the lower mold. If a more stable fixing effect is required, a suction cup can be installed at the bottom of the lower mold, and the screw can be connected to the suction cup through the threaded groove on the base. The adsorption force of the suction cup can be used to further enhance the stability of the mold, thereby preventing gaps between the upper and lower molds, avoiding defects in the molded plug product, and also avoiding the phenomenon of raw material leakage, thereby improving applicability.

[0019] After the mold is assembled and fixed, the molten plastic or other molding material is injected through the feed port on the top side of the upper mold. The feed hole connected to the feed port and the connecting hole is opened inside the upper mold to ensure that the material can flow smoothly into the connecting hole inside the module. The connecting hole is connected to the upper molding cavity and the lower molding cavity, so the material will be filled into these two molding cavities. The upper molding cavity is located on the bottom side of the module, and the lower molding cavity is located on the top side of the lower mold, so that the two molding cavities together constitute the final shape of the wiring harness plug, so as to facilitate the injection molding of the wiring harness plug and improve the applicability. After the material cools and solidifies, the fastening mechanism is loosened, and the upper mold is separated from the lower mold and the module. Then, the molded wiring harness plug is removed from the lower mold. Corresponding sealing gaskets are respectively provided on the bottom and top sides of the upper and lower molds. The sealing gaskets can fit tightly when the mold is closed to prevent material leakage and reduce friction and wear between the molds, ensuring the sealing of the mold during the molding process and protecting the mold from damage.
