Abstract
The utility model belongs to the technical field of the mould and specifically relates to department's section of thick bamboo needle air-cooling mould. The die comprises a die body, a cylinder ejecting needle and an air pipe, wherein the die body is fixedly provided with a plurality of cylinder ejecting needles, air holes are formed in a needle body of each cylinder ejecting needle, the air holes of the cylinder ejecting needles are communicated with the air pipe, and the top end of the air pipe is fixed in the die body. The utility model discloses an outside air supply lets in the department's section of thick bamboo needle with gas through the trachea in, blows off via department's section of thick bamboo needle open-top again. Thus, the heat on the ejector pin can be carried away from the ejector pin through the flow of the gas. The temperature of the ejector pin is reduced. Thereby avoided the department's section of thick bamboo needle to take place the deformation because the temperature is too high, helped injection molding cooling shaping.
Description
Technical Field
The utility model belongs to the technical field of the mould and specifically relates to department's section of thick bamboo needle air-cooling mould.
Background
When the injection molding piece is subjected to injection molding in the injection molding machine, the ejector pin is placed in the injection molding piece. The high temperature of the injection-molded part during injection molding causes the temperature of the ejector pin to be high. When the ejector pin is too hot, deformation can take place, influence the quality of injection molding to be unfavorable for the injection molding cooling to take off the material. However, since the barrel needle body is too thin, a water loop cannot be formed in the needle body, and the barrel needle is not suitable for water cooling in the barrel needle body.
SUMMERY OF THE UTILITY MODEL
In order to solve the technical problem described in the background art, the utility model provides an department's section of thick bamboo needle air-cooling mould. An external gas source leads gas into the ejector sleeve needle through a gas pipe and then blows the gas out through the top opening of the ejector sleeve needle. Thus, the heat on the ejector pin can be carried away from the ejector pin through the flow of the gas. The temperature of the ejector pin is reduced. Thereby avoided the department's section of thick bamboo needle to take place the deformation because the temperature is too high, helped injection molding cooling shaping.
The utility model provides a technical scheme that its technical problem adopted is:
the cylinder ejecting needle air cooling mold comprises a mold body, a cylinder ejecting needle and an air pipe, wherein a plurality of cylinder ejecting needles are fixed on the mold body, air holes are formed in needle bodies of the cylinder ejecting needles, the air holes of the cylinder ejecting needles are communicated with the air pipe, and the top end of the air pipe is fixed in the mold body.
Specifically, the tail end of the air pipe is fixed in the bottom plate, an air inlet hole is formed in the side end of the bottom plate, an air passage is formed in the bottom plate, and the air inlet hole is communicated with the opening of the tail end of the air pipe through the air passage.
Specifically, the end surface of the top of the needle body of the ejector sleeve needle is provided with an air outlet nozzle, and the surface area of the air outlet nozzle is smaller than that of the end surface of the top of the needle body of the ejector sleeve needle.
The utility model has the advantages that: the utility model provides an department's section of thick bamboo needle air-cooling mould. An external gas source leads gas into the ejector sleeve needle through a gas pipe and then blows the gas out through the top opening of the ejector sleeve needle. Thus, the heat on the ejector pin can be carried away from the ejector pin through the flow of the gas. The temperature of the ejector pin is reduced. Thereby avoided the department's section of thick bamboo needle to take place the deformation because the temperature is too high, helped injection molding cooling shaping.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
in the figure, 1 is a mould body, 2 is a cylinder ejector, 3 is an air pipe, 4 is a bottom plate, and 5 is an air inlet.
Detailed Description
The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
Fig. 1 is a schematic structural diagram of the present invention.
A cylinder ejecting needle air cooling die comprises a die body 1, cylinder ejecting needles 2 and an air pipe 3, wherein the plurality of cylinder ejecting needles 2 are fixed on the die body 1, and needle bodies of the cylinder ejecting needles 2 are fixed on the die body 1. The needle body of the ejector pin 2 is internally provided with a vent hole, the vent hole of the ejector pin 2 is communicated with the air pipe 3, and the top end of the air pipe 3 is fixed in the mold body 1. The tail end of the air pipe 3 is fixed in the bottom plate 4, an air inlet 5 is arranged at the side end of the bottom plate 4, an air passage is arranged in the bottom plate 4, and the air inlet 5 is communicated with an opening at the tail end of the air pipe 3 through the air passage. The end surface of the top of the needle body of the ejector sleeve needle 2 is provided with an air outlet nozzle, and the surface area of the air outlet nozzle is smaller than that of the end surface of the top of the needle body of the ejector sleeve needle 2.
As shown in the attached figure 1, firstly, the air is introduced into the air passage in the bottom plate 4 from the air inlet 5 by the external air source, enters the air pipe 3 through the air passage, enters the needle body of the ejector pin 2 through the air pipe 3, and is finally blown out from the vent hole in the needle body of the ejector pin 2. The heat transferred from the external injection molding member to the ejector pin 2 is carried away from the ejector pin 2 by the flow of the gas, thereby achieving the purpose of cooling the ejector pin 2 by the gas. When the gas continuously cools the ejector pin 2, the ejector pin 2 can be prevented from being deformed due to overheating, and the cooling forming of the injection molding piece can be facilitated.
In light of the foregoing, it will be apparent to those skilled in the art from this disclosure that various changes and modifications can be made without departing from the spirit and scope of the invention. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
