Since the plurality of ejector pins 20 are all fixed on the supporting block 30, when the ejection mechanism 50 drives the supporting block 30 to move towards the flow channel 12, the plurality of ejector pins 20 can be simultaneously pushed towards the flow channel 12 to push out the glue material in the flow channel 12. Therefore, the plurality of ejector pins 20 can be driven to push towards the flow channel 12 at the same time only by abutting the ejection mechanism 50 against the supporting block 30, so that the ejection consistency of the plurality of ejector pins 20 can be ensured, and the sizing material in the flow channel 12 can be ejected better. In addition, since only one ejection mechanism 50 is required to achieve the movement of the plurality of ejector pins 20, for example, one ejector rod 52 may be provided, and the ejector rod 52 moves toward the supporting block 30 and drives the supporting block 30 to move toward the flow channel 12.

Wherein, the restoring member 40 can be rubber, sponge, spring or poke rod, etc. Of course, in other embodiments, the restoring element 40 may be connected to the ejection mechanism and the supporting block 30 or the thimble 20, respectively.

Specifically, in one embodiment, the restoring element 40 is a spring, and the spring is sleeved on the thimble 20. One end of the spring abuts against the surface of the first ejector block 10 away from the flow channel 12, and the other end abuts against the end of the ejector pin 20 away from the flow channel 12. The spring is compressed as the needle 20 is pushed towards the flow passage 12. It can be understood that the spring is simple in structure, and compared with rubber or sponge, the spring is better in structural performance such as elasticity and strength and longer in service life. In one embodiment, one end of the spring abuts the surface of the first top block 10 facing away from the flow channel 12, and the other end abuts the support block 30.

In this embodiment, the first ejector block 10 is an inclined ejector block, and the moving direction of the inclined ejector block is inclined relative to the mold opening direction of the injection mold.

The first top block 10 is slidably connected to the guide portion 71, and when the first top block 10 is driven by the top block link 53 to move along the mold opening direction of the injection mold, the first top block 10 is also slidably connected to the guide portion 71 to move in the first direction, that is, the moving direction of the first top block 10 is inclined to the mold opening direction of the injection mold. So when the product drawing of patterns, first molding surface 11 can keep away from the product surface and separate with the product, can avoid the surface and the first molding surface 11 friction of product, and then can make things convenient for the product drawing of patterns to and improve the surface quality of product. In addition, when the first top block 10 is used for molding the reverse buckle of the product, the first top block 10 can be separated from the reverse buckle, and the product is further preserved and demoulded smoothly. Of course, in other embodiments, the guiding portion 71 may be in a column shape, or the first top block 10 may be provided with a guiding hole, the guiding portion 71 extends into the guiding hole, or the guiding portion 71 may be provided in a guiding rail, and so on.

In this embodiment, the ejection mechanism 50 includes a push plate 51 and a push rod 52 connected to the push plate 51, and the push plate 51 drives the push rod 52 to move towards the thimble 20, so that the push rod 52 drives the thimble 20 to push towards the flow channel 12. Specifically, the push plate 51 is arranged on the movable mold and is positioned on one side of the movable mold plate, which is far away from the fixed mold, and the push plate 51 can move towards the movable mold plate. The ejector rod 52 is fixed on the ejector plate 51 and extends towards the first ejector block 10, and when the ejector plate 51 moves towards the movable die plate, the ejector rod 52 is driven to move towards the first ejector block 10 to drive the support block 30 to push towards the runner 12. Compared with the case that the ejection mechanism 50 is a motor or an oil cylinder, the ejector rod 52 and the push plate 51 have simple structures, so that the mold structure can be simplified, and the cost can be reduced. And the ejector block link 53 connected to the first ejector block 10, a push rod (not shown) for pushing out a product, and a material pulling rod (not shown) may also be fixed to the push plate 51, so that the space utilization of the injection mold may be improved. The push plate 51 may be driven by an injection molding machine, or may be driven by an oil cylinder or a motor. In one embodiment, the ejector pin 52 abuts a surface of the support block 30 facing away from the ejector pin 20.

In this embodiment, the first top block 10 has a molding position where the cavity 80 is formed together with the fixed mold and the movable mold, and an ejection position away from the cavity 80; in the molding position, one end of the ejector rod 52 close to the ejector pin 20 is arranged in a staggered manner with the ejector pin 20 in the first direction; in the ejected position, the ram 52 is aligned with the support block 30. Specifically, one end of the ejector rod 52 close to the ejector pin 20 is spaced apart from the support block 30, the ejector block link 53 and the ejector rod 52 are both provided on the push plate 51, the first ejector block 10 is driven to move by the ejector block link 53 when the push plate 51 moves, and the ejector rod 52 is driven to move toward the support block 30 by the push plate 51. When a product is molded in an injection mold, the first top block 10 is in a molding position, and when the product is demolded, the top block link 53 drives the first top block 10 to move, and the first top block 10 also moves in the first direction by the guide portion 71. When the first ejector block 10 moves to the ejection position, the ejector rod 52 abuts against the supporting block 30, and the ejector rod 52 continues to move towards the supporting block 30 under the continuous driving of the ejector plate 51, and pushes the supporting block 30 towards the flow channel 12, so that the ejector pin 20 ejects the rubber material in the flow channel 12. It will be appreciated that this avoids interference with the ram 52 during movement of the first ram 10. In addition, in one embodiment, the ejection direction of the ejector pins 20 is the same as the ejection direction of the ejector pins 52. Compared with the push rod 52 which moves obliquely, the moving direction of the push rod 52 is the same as the moving direction of the push pin 20, so that the acting force of the push rod 52 abutting against the supporting block 30 is larger, and the driving effect is better. In addition, in another embodiment, the moving direction of the push plate 51 and the push rod is the same as the mold opening direction of the injection mold, and since the push plate 51 is located on the side of the movable mold plate away from the fixed mold, the movable mold plate is provided with a push rod hole for the push rod 52 to pass through the fixed mold plate and abut against the supporting block 30. When the ejector rod 52 is arranged in this way, the axis of the ejector rod hole can be perpendicular to the surface of the fixed die plate, so that the ejector rod hole can be conveniently machined, and the cost of the injection mold can be reduced.

In this embodiment, the injection mold further includes a second top block 60, the first top block 10, the fixed mold and the movable mold together form a mold cavity 80, and the second top block 60 is slidably connected to the movable mold and can move along the mold opening direction of the injection mold. Specifically, the second top block 60 has a second molding surface 61 for molding the product, and the second molding surface 61 is disposed toward the first molding surface 11. The push plate 51 is provided with a plurality of top block links 53, the plurality of top block links 53 are respectively connected with the first top block 10 and the second top block 60 to drive the first top block 10 to move along the mold opening direction of the injection mold, and the first molding surface 11 can move in the direction away from the second molding surface 61 because the second top block 60 is slidably connected with the guide portion 71 and also moves along the first direction. Therefore, an included angle is formed between the ejection direction of the first ejector block 10 and the ejection direction of the second ejector block 60, so that shearing force can be generated to break the product and the rubber material in the flow channel 12, the product can be prevented from being jammed during demolding, and the smoothness during demolding is improved. In addition, the second molding surface 61 contacts with the inner surface of the product, and after the product is molded, the second ejector block 60 moves along the mold opening direction of the injection mold to eject the product out, and the second ejector block 60 is arranged to increase the contact area with the product, so that the demolding effect and the surface quality of the product can be improved.

When a product is molded by an injection mold, in a mold closing state, the movable mold, the fixed mold, the first top block 10 and the second top block 60 form a mold cavity for molding the product. When the product is demoulded, the movable mold is far away from the fixed mold along the mold opening direction of the injection mold, and then the push plate 51 moves towards the movable mold, so that the first ejector block 10 and the second ejector block 60 are driven to move far along the mold opening direction through the ejector block connecting rod 53, and the second ejector block 60 and the push rod fixed on the push plate 51 can push out the product. Because the first ejector block 10 can move along the first direction while moving along the mold opening direction, the rubber material in the runner 12 can be disconnected from the product, and the product can be smoothly pushed out of the mold. And when the first ejector block 10 moves to the ejection position, the ejector rod 52 abuts against the supporting block 30, and the ejector rod 52 continues to move towards the supporting block 30 under the action of the push plate 51, and pushes the supporting block 30 towards the flow channel 12, so that the ejector pin 20 ejects the rubber material in the flow channel 12, and the return element 40 elastically deforms when the supporting block 30 moves. After the product and the rubber material are separated from the injection mold, the push plate 51 moves far in the opposite direction, so as to drive the first ejector block 10 and the ejector rod 52 to reset, and after the ejector rod 52 is far away from the supporting block 30, the supporting block 30 moves towards the direction far away from the flow channel 12 under the action of the resetting piece 40, so as to reset. And finally, closing the fixed die and the movable die to perform the next work.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
