Detailed Description
The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.
As shown in fig. 1, the feeding structure of the injection molding machine comprises: the valve comprises a valve body 1, a valve body cover, a valve core and a valve core, wherein a mounting hole 2 and a circulation hole 3 are longitudinally formed in the valve body 1, the mounting hole 2 is communicated with the circulation hole 3, a feeding hole 4 and a discharging hole 5 are transversely formed in the lower part of the valve body 1, and the discharging hole 5, the feeding hole 4 and the mounting hole 2 are communicated; the supporting seat 6 is inserted at the lower end of the valve body 1, a supporting column 7 is arranged on the supporting seat 6, and the supporting column 7 penetrates through the feeding hole 4 and the discharging hole 5 and extends into the mounting hole 2; the spherical valve core 8 is arranged in the mounting hole 2 and movably abutted against the supporting column 7; when the ball valve core 8 moves upwards, the top end of the ball valve core 8 is inserted into the circulation hole 3 and cuts off the circulation hole 3 and the mounting hole 2.
Before injection molding, raw materials are firstly melted, the spherical valve core 8 is abutted against the upper end of the supporting column 7, a certain gap is reserved between the top end of the spherical valve core 8 and the top end of the mounting hole 2 at the moment, the melted raw materials can enter the mounting hole 2, the melted raw materials in the mounting hole 2 can enter the feeding hole 4 because the mounting hole 2 is communicated with the feeding hole 4, the purpose of storing the materials is achieved, after the materials are stored, the step of injecting the materials is started, when the materials are injected, the stored raw materials enter the feeding hole 4, because the feeding hole 4 is communicated with the mounting hole 2, the raw materials can enter the mounting hole 2 and contact with the lower end of the spherical valve core 8, the raw materials can drive the spherical valve core 8 to move upwards, the top end of the spherical valve core 8 can be inserted into the circulation hole 3, so that the circulation hole 3 and the mounting hole 2 can be separated, the raw materials in the mounting hole 2 are prevented from flowing, and then the raw materials can enter into discharge opening 5 when guaranteeing to mould plastics to penetrate the material, realizes moulding plastics and penetrates the material purpose.
The ball valve core 8 moves upwards and depends on the raw material in the feed port 4 entering the mounting hole 2 as the drive, the structure is simple, the additional driving device can be reduced, the manufacturing cost is reduced, and when the storage mode is switched, the raw material in the circulation hole 3 downwards extrudes the ball valve core 8, the ball valve core 8 can be driven to move downwards, the switching speed is high, and the influence of other devices cannot be caused.
The diameter of the spherical valve core 8 is larger than that of the circulation hole 3, so that the spherical valve core 8 can not be completely inserted into the circulation hole 3, the smoothness degree of the spherical valve core 8 during up-and-down movement is improved, and the spherical valve core 8 can be completely separated from the circulation hole 3 and the mounting hole 2.
The lower end of the valve body 1 is connected with a glue injection cylinder 9 and a glue injection cylinder 10, the glue injection cylinder 9 is communicated with the discharge hole 5, and the glue injection cylinder 10 is communicated with the feed hole 4.
During the storage, the raw materials in the circulation hole 3 get into the feed port 4 through the mounting hole 2, because the feed port 4 communicates with a rubber injection section of thick bamboo 10, so the raw materials can be stored to a rubber injection section of thick bamboo 10 in, penetrate when a rubber injection section of thick bamboo 9 is used for moulding plastics and penetrate the material, penetrate during the storage and be vacuum state in the rubber injection section of thick bamboo 9, so the raw materials during the storage can not get into to penetrating in the rubber injection section of thick bamboo 9.
The upper end of the valve body 1 is connected with a sol cylinder 11, and the sol cylinder 11 is communicated with the circulation hole 3.
The sol cylinder 11 is used for melting the raw material, and then sending the melted raw material into the circulation hole 3.
The specific embodiments described herein are merely illustrative of the spirit of the invention. Various modifications, additions and substitutions for the specific embodiments described herein will be apparent to those skilled in the art without departing from the scope and spirit of the invention as defined in the accompanying claims.
