Abstract

This utility model discloses an injection mold for a socket housing, including an ejector plate, ejector pins, a slider assembly, a front mold insert, a rear mold insert, a front mold pin, a rear mold pin, and a panel, an upper mold plate, a lower mold plate, a square iron, and a base plate arranged from top to bottom. A front mold core is located below the upper mold plate, and a rear mold core is located above the lower mold plate. The front and rear mold cores correspond to form a cavity. The bottom end of the front mold pin has a groove, and the top end of the rear mold pin has a protrusion that engages with the groove. A first ventilation groove and a second ventilation groove are provided around the outer periphery of the front mold pin, and the first and second ventilation grooves are connected. When the mold is closed for injection molding, the air inside the cavity is gradually compressed by the injection molding compound and enters the first ventilation groove through the gap between the front mold pin and the front mold insert, then exits through the second ventilation groove to the outside of the cavity. This prevents air accumulation inside the cavity and effectively prevents the formation of air holes on the molded product.

Specifically, when the die needs to be clamped, the upper die plate 9 moves downwards, and is close to the lower die plate 10, when the upper die plate 9 moves downwards, the guide block 36 and the inclined guide rod 33 are driven to move downwards, so that the inclined guide rod 33 is inserted into the moving block 32, the moving block 32 moves towards one cavity under the action of the inclined guide rod 33, and when the moving block 32 moves, the sliding block 31 is driven to synchronously move towards one side of the cavity. When the upper die plate 9 and the lower die plate 10 are moved into position, injection molding can be performed into the cavity. After the upper die plate 9 moves downwards to the proper position, the guide block 36 is pressed on the outer side of the moving block 32, so that the moving block 32 is prevented from moving outwards during injection molding, and the injection molding quality of products in the cavity is ensured.

After the injection molding of the product in the cavity is completed, the upper template 9 moves upwards to drive the inclined guide rod 33 to move upwards, and the moving block 32 is pushed to move to the side far away from the cavity under the action of the inclined guide rod 33, so that the sliding block 31 is driven to move to the side far away from the cavity, the separation of the sliding block 31 and the product is realized, and the product is convenient to demould.

The rear mold insert 5 which is matched with the rear mold insert 7 is provided with a through hole 51, the through hole 51 is horizontally arranged, the rear mold insert 7 vertically penetrates through the through hole 51, and the other end of the side insert 34 can extend into the through hole 51. Wherein, the through hole 51 is located below the cavity, and when the cavity is injected, air in the cavity can also enter the through hole 51 along the gap between the rear mold insert needle 7 and the rear mold insert 5, thereby avoiding air accumulation in the cavity and preventing air holes from forming on the product. In actual injection molding, the clearance between the rear mold insert pin 7 and the rear mold insert 5 allows air to pass through, but the gel in injection molding cannot pass through.

The socket shell injection mold further comprises a reset spring 60 and a mounting rod 70, wherein one end of the mounting rod 70 is fixed on the ejector plate 1, the other end of the mounting rod can penetrate through the lower die plate 10, the reset spring 60 is sleeved on the mounting rod 70, one end of the reset spring 60 is abutted against the ejector plate 1, and the other end of the reset spring is abutted against the lower die plate 10. When the ejector pin plate 1 moves upwards, the reset spring 60 is compressed, and when the ejector pin 2 ejects materials, the rebound force of the reset spring 60 pushes the ejector pin plate 1 to move downwards for reset, so that reset is completed, and the next die assembly and die opening are facilitated.

The opening and closing process of the socket shell injection mold provided by the utility model is specifically as follows:

When the die is matched, the upper die plate 9 and the lower die plate 10 are tightly pressed, the front die core 40 is matched with the rear die core 50, the sliding block 31 moves to one side of the die cavity and is matched with the die cavity, and the die is matched with the die cavity. And after the die assembly is completed, injection molding is carried out in the die cavity, so that the corresponding socket shell is obtained.

After the injection molding of the product is completed, the mold is opened, the panel 8 and the upper template 9 move upwards, and the upper template 9 drives the sliding block 31 to be far away from the cavity, so that the sliding block 31 is separated from the product. Along with the gradual upward movement of the upper template 9, the upper template 9 drives the inclined guide rods 3 to move upward together, and the sliding blocks 4 are pushed to move outwards integrally under the guiding action of the inclined guide rods 3, so that the second moving blocks 42 are completely separated from the product. When the upper die plate 9 moves upwards to a proper position, the front die core 40 is separated from the product, the ejector plate 1 moves upwards, the ejector plate 1 drives the ejector pins 2 to move upwards, and the ejector pins 2 eject the product out of the die cavity upwards, so that the product is demolded.

The foregoing is merely a preferred embodiment of the present utility model, and it should be noted that modifications and improvements could be made by those skilled in the art without departing from the inventive concept, which fall within the scope of the present utility model.
