Embodiment 2

Referring to Figures 3 and 4, an improvement based on the first embodiment: an RCBO housing injection mold, which is applied to the field of injection mold technology;

In this embodiment, two fixed blocks 10 are fixedly installed on both sides of the sealing frame 7, and guide rods 11 are slidably penetrated in the multiple fixed blocks 10. The bottom ends of the multiple guide rods 11 are fixedly connected to the top of the bottom plate 1, and the outer walls of the multiple guide rods 11 are sleeved with first return springs 12. One end of the multiple first return springs 12 is fixedly connected to the top of the bottom plate 1, and the other end of the multiple first return springs 12 is fixedly connected to the bottom of the adjacent fixed blocks 10. The guide rods 11 and the first return springs 12 can facilitate the movement and rebound of the sealing frame 7. The sealing frame 7 is slidingly and sealingly connected to the two ejection blocks 8 through two through grooves. Two injection pipes 9 are fixedly connected to one side of the sealing frame 7. One end of the two injection pipes 9 cooperates with the cavity formed between the lifting plate 6, the sealing frame 7, and the ejection block 8. The other ends of the two injection pipes 9 are connected to the external feeding equipment. The multiple first return springs 12 can easily make the sealing frame 7 quickly return to its original position, which is convenient for the next injection molding.

In this embodiment, the interior of the two mold plates 13 is sealed and slidably penetrated by two push rods 14, one end of the two adjacent push rods 14 penetrates the lifting plate 6 and is fixedly installed with the same connecting plate 15, the outer walls of the multiple push rods 14 are sleeved with second return springs 16, one end of the multiple second return springs 16 is fixedly connected to the top of the lifting plate 6, and the other ends of the multiple second return springs 16 are fixedly connected to the bottom of the adjacent connecting plate 15, and the two connecting plates 15 are matched with the bottom of the top plate 3. When the lifting plate 6 rises, one end of the push rod 14 extends from the bottom of the mold plate 13, so that the molded RCBO shell can be pushed out of the injection molding groove.

In this embodiment, when the lifting plate 6 descends to the lowest point, the bottoms of the two mold plates 13 are in close contact with the tops of the adjacent ejection blocks 8, which can make the shape of the injection-molded RCBO shell more precise.

However, as is well known to those skilled in the art, the working principle and wiring method of the cylinder 4 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any selections according to their needs or convenience.

The use process and working principle of the technical solution of this utility model are as follows:

During use, the user can drive the lifting plate 6 to descend through the cylinder 4 until both mold plates 13 are inserted into the through grooves of the sealing frame 7 and until the bottom of the mold plate 13 is in close contact with the top of the ejector block 8. Then the user can use the injection pipe 9 to inject raw materials into the injection groove at the bottom of the mold plate 13 until the RCBO shell is formed. When the user needs to demould, the user only needs to control the cylinder 4 to drive the lifting plate 6 to rise. After the lifting plate 6 rises, it will drive the push rod 14 and the connecting plate 15 to rise synchronously until the connecting plate 15 abuts against the bottom of the top plate 3. As the lifting plate 6 continues to rise, the push rod 14 and the connecting plate 15 will rise synchronously. The bottom end of the push rod 14 will extend out of the bottom of the mold plate 13, and the RCBO shell adhered to the injection groove can be pushed out. The RCBO shell will fall into the sealing frame 7 under the action of gravity and be placed on the ejection block 8; when the lifting plate 6 rises, it will drive the first connecting slide bar 18 to rise synchronously, and push the second connecting slide bar 19 down under the linkage of the connecting rocker rod 17. The second connecting slide bar 19 can press the protrusion 20 when descending, and can push the sealing frame 7 to move downward until the RCBO shell is placed on the ejection block 8, which can facilitate users to complete material removal.
