Problems solved by technology

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 implementation manners of the present invention will be further described below in conjunction with the accompanying drawings, so as to make the technical solution of the present invention easier to understand and grasp.

[0032] A motorcycle cowl injection mold, such as figure 1 , figure 2 As shown, a mold body 1 is included, and the mold body 1 includes a fixed mold and a movable mold. After the fixed mold and the movable mold are interlocked, a mold cavity 2 for molding a motorcycle dash panel is formed between the fixed mold and the movable mold.

[0033] Such as figure 2 , image 3 As shown, the mold body 1 is provided with a vent hole 3, one end of the vent hole 3 communicates with the mold cavity 2, and the other end passes through the outer wall of the mold body 1 and communicates with the outside world. When using an injection molding machine to inject molten plastic into the mold cavity 2 , the air in the mold cavity 2 can be exhausted throug...

Abstract

The invention provides an injection mould for a front wall plate of a motorcycle. The injection mould comprises a mould body internally provided with a mould cavity; an exhaust hole communicating withthe mould cavity is formed in the outer wall of the mould body; the hole diameter of the exhaust hole is gradually increased away from one side of the mould cavity; an adjusting mechanism is arrangedin the exhaust hole; the adjusting mechanism comprises a support, an adjusting block and an elastic piece; the support is connected to the mould body; the adjusting block is connected to the supportin a sliding mode; the elastic piece is connected between the support and the adjusting block; the elastic piece applies elastic force to the adjusting block to point to one side of the mould cavity;and the adjusting block is tightly attached to the inner wall of the exhaust hole under the action of the elastic force. When the injection speed of molten plastic is increased, the acting force applied to the adjusting block by air in the mould cavity is increased, so that the adjusting block continuously moves towards one side far away from the mould cavity; furthermore, the gap between the adjusting block and the exhaust hole is increased; therefore, the air in the mould cavity can be exhausted more quickly; and the situation of insufficient filling or glue burning is not easy to occur.

Description

technical field [0001] The invention relates to an injection mold, in particular to an injection mold for a front panel of a motorcycle. Background technique [0002] At present, the Chinese patent with the notification number CN206748922U discloses an injection mold for the dash panel of an electric vehicle, including 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 dash panel of the electric vehicle. [0003] Before the molten plastic is injected into the cavity, the cavity is filled with air. In order to produce better quality products, it is necessary to open vent holes on the fixed mold and / or movable mold to quickly discharge the air in the mold cavity. However, the shape of the vent hole provided on the fixed mo...
