[0012] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0013] See Figure 2 、 Figure 3 、 Figure 4 and Figure 5 A wire harness device mold tensile device mold structure includes a front mold 1 and a rear mold 2, the front mold 1 and the rear mold 2 are connected by a guide column 3, a front mold core 4 is provided on the front mold 1, and a front mold cavity 5 is provided on the front mold core 4, and the front mold cavity 5 is connected to the gate 7 through a runner 6, and a rear mold core 8 is provided on the rear mold 2 corresponding to the front mold core 4, and a rear mold cavity 9 is provided on the rear mold core 8. A plurality of columnar cores 10 are provided on the upper end of the rear mold 2 corresponding to the rear mold core 8, and the columnar core 10 extends into the front mold core 4. When the front and rear molds are separated, the columnar hole is formed by the columnar core, and the strip-shaped notch is formed by the front mold core. The above mold structure is used to realize one-time molding of the product in the mold, thereby improving the molding efficiency of the product and effectively reducing the production cost.

[0014] The front mold 1 includes a front mold connecting plate 11, a diverter plate 12, and a front mold plate 13. The front mold core 4 is set on the front mold plate 13. The rear mold 2 includes a rear mold connecting plate 14 and a rear mold plate 15. The rear mold core 8 is set on the rear mold plate 15. The specific structure of the front mold and the rear mold determines the position of the diverter plate and ensures the separation of the front and rear molds.

[0015] The columnar core 10 is connected to the core runner 16 , and the core runner 16 is connected to the runner 6 , so as to realize material pouring of the product cavity formed by the multiple columnar cores and the front mold core and the rear mold core.

[0016] The front mold core 4 and the rear mold core 8 are provided with water channels 17 to achieve rapid cooling of the mold, ensure the stability of product molding, and at the same time ensure the production efficiency of the product.

[0017] A hot runner 18 is provided on the front template 13 corresponding to the gate 7. The hot runner corresponds to a heating device, which ensures that the material maintains a good flow state after entering the mold after melting.

[0018] The rear mold connecting plate 14 and the rear mold plate 15 are connected by a bracket 19 to form a cavity 20. An ejector base plate 21 is provided in the cavity 20. The ejector base plate 21 is guided and connected by an ejector guide column 22. The ejector base plate 21 is connected to the rear mold plate 15 through a compression spring 23. An ejector 24 is provided on the ejector base plate 21. The ejector 24 corresponds to the core runner 16. When the front and rear molds are separated, the core runner is ejected to separate the core runner from the product.

[0019] The columnar core 10 passes through the ejector base plate 21 and is connected to the rear mold connecting plate 14, thereby ensuring the stability of the installation of the columnar core.

[0020] The plurality of columnar cores 10 correspond to the product cavities formed by the plurality of front mold cavities and the rear mold cavities, thereby enabling the simultaneous molding of multiple products on one mold, thereby improving production efficiency and reducing production costs.

[0021] The above schematically describes the present invention and its implementation methods. This description is not restrictive. What is shown in the accompanying drawings is only one of the implementation methods of the present invention. The actual structure is not limited to this.
