The upper surface middle part of the upper mold offers injection hole, and injection hole is connect by gate spool with EU case forming cavities, described Upper mold is provided with air hole close to the both sides of injection hole, and air hole is connected with EU case forming cavities, the upper mold close to EU casees into Upper mold cooling tube is provided on the upside of cavity, and one end of upper mold cooling tube is provided with connector, the connector connects with casing It connects, the water outlet connection of the upper mold cooling tube one end and water pump far from connector.
Preferably, the upper mold is both provided with lifting lug on the inside of supporting rod.
Preferably, the top of the supporting rod is fixedly installed limited block.
A kind of injection mold of EU casees proposed by the present invention, advantageous effect are:Lower die and upper mold are passed through into support first Bar connects, and lower die is made to form EU case forming cavities with upper mold, then injects liquid plastics from injection hole, and liquid plastics pass through gate spool EU case forming cavities are flowed into, after the completion of injection, outer tank is accessed at the nearly mouth of a river of water pump, then start water pump, while by water Valve is opened, and cooling liquid is discharged into upper mold cooling tube from the water outlet of water pump, and cooling liquid flows to lower die cooling from upper mold cooling tube Pipe, step by step cools down the liquid plastics in EU case forming cavities, and the top of upper mold is provided with air hole, ensures while cooling The gas of generation can be smoothly discharged out, and after the completion of cooling, be switched off the pump, while water valve is closed, and effectively accelerates cooling Speed, while improve the working efficiency of the present invention.
Description of the drawings
Fig. 1 is a kind of structure diagram of the injection mold of EU casees proposed by the present invention;
Fig. 2 is enlarged structure schematic diagram at a kind of A of the injection mold of EU casees proposed by the present invention.
In figure:Lower die 1, upper mold 2, supporting rod 3, lifting lug 4, air hole 5, injection hole 6, gate spool 7, mandril 8, upper mold cooling Pipe 9, EU casees forming cavity 10, lower die cooling tube 11, water valve 12, water pump 13, casing 14, connector 15.
Specific embodiment
Below in conjunction with the attached drawing in the embodiment of the present invention, the technical solution in the embodiment of the present invention is carried out clear, complete Site preparation describes, it is clear that described embodiment is only part of the embodiment of the present invention, instead of all the embodiments.
With reference to Fig. 1-2, a kind of injection mold of EU casees, including lower die 1 and upper mold 2, the upper surface quadrangle of lower die 1 is respectively provided with Have supporting rod 3, and upper mold 2 be arranged on supporting rod 3, the top of supporting rod 3 is fixedly installed limited block, prevent upper mold 2 from It comes off on supporting rod 3, upper mold 2 is both provided with lifting lug 4 close to the inside of supporting rod 3, facilitates lifting upper mold, reduces artificial, raising Working efficiency, upper mold 2 and lower die 1 form EU casees forming cavity 10, and it is cold that lower die 1 close to the downside of EU casees forming cavity 10 is provided with lower die But pipe 11, one end of lower die cooling tube 11 are provided with casing 14, and the one end of lower die cooling tube 11 far from casing 14 is provided with water valve 12, the middle part of lower die 1 is provided with mandril 8, accelerates to take the speed of EU casees, improves working efficiency.
The upper surface middle part of upper mold 2 offers injection hole 6, and injection hole 6 is connected by gate spool 7 and EU casees forming cavity 10 It connects, upper mold 2 is provided with air hole 5 close to the both sides of injection hole 6, and air hole 5 is connected with EU casees forming cavity 10, and upper mold 2 is close The upside of EU casees forming cavity 10 is provided with upper mold cooling tube 9, and one end of upper mold cooling tube 9 is provided with connector 15, connector 15 connect with casing 14, and the one end of upper mold cooling tube 9 far from connector 15 is connect with the water outlet of water pump 13, can quickly by The product cooling of injection molding improves the cooling velocity of the device.
