BRIEF DESCRIPTION OF THE DRAWINGS

[0015] Figure 1 The present invention provides a schematic structural diagram of a wire harness sheath structure mold.

[0016] Figure 2 The present invention provides a schematic structural diagram of the cooperation between a lower mold plate and a mold core assembly of a wire harness sheath structure mold. DETAILED DESCRIPTION

[0017] like Figure 1 and 2 As shown, Figure 1 This is a schematic diagram of the structure of a wire harness sheath structure mold proposed by the present invention. Figure 2 The present invention provides a schematic structural diagram of the cooperation between a lower mold plate and a mold core assembly of a wire harness sheath structure mold.

[0018] Reference Figure 1 and 2 The present invention provides a wire harness sheath structure mold, comprising: an upper mold plate 1, a lower mold plate 2 and a mold core assembly;

[0019] An upper mold cavity is provided at the bottom of the upper mold plate 1 and a lower mold cavity is provided at the top of the lower mold plate 2. The upper mold plate 1 is located above the lower mold plate 2, and the mold core assembly is located between the upper mold plate 1 and the lower mold plate 2.

[0020] The core mold assembly includes a crossbeam 3 and multiple core molds 4. Both ends of the crossbeam 3 are provided with mold lifting frames 5. The multiple core molds 4 are respectively located on both sides of the crossbeam 3 and one end of the core mold 4 is fixed to the crossbeam 3. The upper mold cavity, the lower mold cavity and the core mold 4 cooperate to form a mold cavity. A connecting rod 6 is provided at the end of the mold lifting frame 5 and is connected to the upper mold plate 1 through the connecting rod 6.

[0021] During the specific working process of the wire harness sheath structure mold of this embodiment, when injecting glue, a sheath product is formed in the cavity surrounding the mold core. After molding, the upper mold plate moves up, the cavity opens, and the lifting mold frame of the core assembly is driven up by the connecting rod, so that the sheath product outside the core moves up with the upper mold plate and is demolded from the lower mold cavity.

[0022] In this embodiment, the proposed wire harness sheath structure mold has a core assembly located between the upper mold plate and the lower mold plate surface; the core assembly includes a crossbeam and a plurality of cores, both ends of the crossbeam are provided with a mold lifting frame, the plurality of cores are respectively located on both sides of the crossbeam and one end of the core is fixed to the crossbeam, the upper mold cavity, the lower mold cavity and the core cooperate to form a cavity, the end of the mold lifting frame is provided with a connecting rod and is connected to the upper mold plate through the connecting rod. Through the above-mentioned optimized design of the wire harness sheath structure mold, through the design of the model assembly, the formation and synchronous molding of multiple cavities are realized, and in the process of mold opening, the upper mold drives the core assembly through the connecting rod, which is convenient for the product to be demolded during the mold opening process and improves the processing efficiency.

[0023] In a specific embodiment, it also includes a flow channel plate 7, which is located on the top of the upper mold plate 1. The flow channel plate 7 is provided with a glue injection flow channel connected to the cavity; when injecting glue, the glue is injected into the cavity through the glue injection flow channel on the flow channel plate.

[0024] In the specific connection method between the core mold assembly and the upper mold plate, a horizontally extending first rotating shaft 81 is respectively provided at both ends of the mold lifting guard frame 5, and a plurality of second rotating shafts 82 are provided at the end of the upper mold plate 1, and each of the second rotating shafts 82 is arranged in parallel with one of the first rotating shafts 81. The connecting rod 6 is arranged obliquely and its two ends are rotatably connected to the mold lifting guard frame 5 and the upper mold plate 1 through the first rotating shaft 81 and the second rotating shaft 82 respectively. When the mold lifting guard frame moves up with the upper mold plate, due to the gravity of the core mold assembly, the connecting rod rotates from an inclined state to a vertical state, so that the core mold assembly moves horizontally with the connecting rod, thereby improving the demolding effect and preventing the product from being damaged secondary during the demolding process.

[0025] In a further specific design, the upper end of the connecting rod 6 is provided with a first waist-shaped groove extending along its length direction, and the connecting rod 6 is sleeved on the outside of the second rotating shaft 82 through the first waist-shaped groove; the connecting rod and the second rotating shaft are connected through a waist-shaped hole. When the upper template moves up, due to the existence of the waist-shaped hole, there is a certain relative movement between the upper template and the core assembly, so that the upper template is first demolded from the product, and then the core assembly is driven to move up and demolded from the lower template.

[0026] Alternatively, in other specific embodiments, the lower end of the connecting rod 6 is provided with a second waist-shaped groove extending along its length direction, and the connecting rod 6 is sleeved on the outside of the first rotating shaft 81 through the second waist-shaped groove, which can also realize the relative movement of the upper template and the core assembly.

[0027] Since the sheath product is provided with circumferentially arranged protrusions, in order to further prevent secondary damage to the product during demolding, the first rotating shaft 81 and the second rotating shaft 82 are arranged parallel to the extension direction of the core 4, so that the core assembly moves with the upper template perpendicular to the extension direction of the core.

[0028] Since the core mold assembly deviates when it rises, in other specific embodiments, two frame receiving grooves for accommodating the mold lifting frame 5 are provided on the top of the lower mold plate 2, and the two frame receiving grooves are respectively located on both sides of the lower mold cavity; this facilitates positioning of the core mold assembly when closing the mold and improves processing accuracy.

[0029] In other specific embodiments, a support spring 9 is provided at the bottom of the guard frame accommodating groove. After the mold is opened, when the upper mold plate moves up and demolds the product, the core assembly is pushed upward under the elastic action of the support spring, thereby achieving simultaneous demolding from the lower mold plate and improving demolding efficiency.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
