However, the shape of the vent hole on the fixed mold and / or movable mold is fixed and cannot be adjusted according to the filling speed of the molten plastic
In this way, when increasing the filling speed of molten plastic, the air in the mold cavity cannot be discharged in time, resulting in back pressure in the mold cavity, resulting in insufficient filling or glue burning

Embodiment Construction
[0031] The specific embodiments of the present invention will be described in further detail below in conjunction with the accompanying drawings, so as to make the technical solutions of the present invention easier to understand and grasp.
[0032] A motorcycle front panel injection mold, such as figure 1 , figure 2 As shown, it includes a mold body 1. The mold body 1 includes a fixed mold and a movable mold. After the fixed mold and the movable mold are engaged with each other, a cavity 2 is formed between the fixed mold and the movable mold for forming a motorcycle dash panel.
[0033] like figure 2 , image 3 As shown, the mold body 1 is provided with an exhaust hole 3, one end of the exhaust hole 3 communicates with the mold cavity 2, and the other end penetrates the outer side wall of the mold body 1 and communicates with the outside world. When the injection molding machine is used to inject molten plastic into the mold cavity 2 , the air in the mold cavity 2 can b...

The invention provides a motorcycle dash panel injection mold, which comprises a mold body with a mold cavity inside, and an air vent connected to the mold cavity is opened on the outer wall of the mold body; the hole of the air vent is radially away from the mold cavity One side gradually increases; an adjustment mechanism is provided in the vent hole, and the adjustment mechanism includes a bracket connected to the mold body, an adjustment block slidably connected to the bracket, and an elastic member connected between the bracket and the adjustment block. The regulating block exerts an elastic force directed to one side of the mold cavity, and the regulating block is in close contact with the inner wall of the vent hole under the action of the elastic force. When the injection speed of the molten plastic increases, the force exerted by the air in the cavity on the regulating block increases, so that the regulating block continues to move away from the cavity, and the gap between the regulating block and the vent hole increases, so that the cavity The air in it can be discharged more quickly, and it is not easy to have insufficient filling or glue burning.
Description
technical field [0001] The invention relates to an injection mold, in particular, to an injection mold for a motorcycle front panel. Background technique [0002] At present, the Chinese patent with the publication number CN206748922U discloses an electric vehicle front panel injection mold, which includes a fixed mold and a movable mold. When the fixed mold and the movable mold are fastened together, a mold cavity is formed between the fixed mold and the movable mold. When in use, the molten plastic is injected into the mold cavity by pressure, and the molten plastic is cooled in the mold cavity to form the front wall of the electric vehicle. [0003] The cavity is filled with air before molten plastic is injected into the cavity. In order to produce better quality products, vent holes need to be provided on the fixed mold and / or the movable mold to quickly exhaust the air in the mold cavity. However, the shape of the vent holes opened in the fixed mold and / or the movable...
