Optionally, the stripper plate further comprises a guide pin, and the guide pin is fixed with the panel and movably penetrates through a guide hole in the small stripper plate.
Optionally, the rear template is mounted on the bottom plate, the bottom plate is provided with mold feet, and the bottom plate, the mold feet and the rear template are fixed together through screws.
Optionally, the ejector pin further comprises an ejector pin, and the ejector pin is connected with the ejector pin panel and the ejector pin base plate.
Optionally, a supporting spring and a nylon rubber plug are arranged between the front template and the rear template, the acting force of the supporting spring on the front template is opposite to the mold closing direction of the rear template, the nylon rubber plug is arranged on the surface of one side of the front template facing the rear template, and the nylon rubber plug can be connected with or separated from the rear template in a sliding manner along the mold opening and closing direction.
The above technical scheme is adopted in the utility model, dig hidden groove in the panel to set up little flitch of taking off in hiding the groove, it is the same with the function of taking off the flitch greatly in the primary structure to take off the flitch for a short time, and the pull rod motion is ejecting little flitch of taking off through connecting rod and cushion, thereby deviates from the mouth of a river material, reaches the same function of conventional three-plate mold structure.
Therefore, the following beneficial effects are achieved: because the small stripper plate is arranged in the hidden groove, the total mold thickness can be reduced, the injection molding machine is more suitable for wide injection molding machine models, the mold frame cost can be saved, and the injection molding machine is more obvious in a three-plate mold with a large product projection area and a large glue inlet point area ratio.
The specific technical solution and the advantages of the present invention will be described in detail in the following detailed description with reference to the accompanying drawings.
Drawings
The invention will be further described with reference to the accompanying drawings and specific embodiments:
FIG. 1 is a front view of the plastic mold of the present invention;
FIG. 2 is a top view of the plastic mold of the present invention;
in the figure: 1. the material-removing die comprises a panel, 2 a small stripper plate, 3 a front die plate, 4 a rear die plate, 5 a die foot, 6 an ejector pin panel, 7 an ejector pin bottom plate, 8 a bottom plate, 9 a front die core, 10 a rear die core, 11 a pull rod, 12 a nylon rubber plug, 13 a nozzle material, 14 a connecting rod, 15 a cushion block and 16 a guide pin.
Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. The following description of at least one exemplary embodiment is merely illustrative in nature and is in no way intended to limit the invention, its application, or uses. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.
It is to be understood that the features of the following examples and embodiments may be combined with each other without conflict.
It is to be understood that the following terms "upper", "lower", and the like, which indicate an orientation or positional relationship, are based only on the orientation or positional relationship shown in the drawings and are used only for convenience in describing the present invention and for simplicity in description, and do not indicate or imply that the devices/elements referred to must have a particular orientation or be constructed and operated in a particular orientation and, therefore, should not be taken as limiting the present invention.
As shown in fig. 1 and 2, a plastic mold capable of reducing the thickness of the mold includes a panel 1, a front mold plate 3, and a rear mold plate 4 sequentially arranged from top to bottom, wherein the front mold plate 3 is connected to a front mold core 9, the rear mold plate 4 is connected to a rear mold core 10, and the front mold core 9 and the rear mold core 10 form a mold cavity.
The hidden groove is formed in one side, facing the front template, of the panel 1, the small stripper plate 2 is arranged in the hidden groove, the small stripper plate 2 is connected with a cushion block 15 and a connecting rod 14, the connecting rod 14 is connected with a pull rod 11, the pull rod 11 moves, and the small stripper plate 2 is ejected out through the connecting rod 14 and the cushion block 15, so that the nozzle material 13 is stripped.
In addition, the device also comprises a guide pin 16 and a guide post, wherein the guide pin is fixed with the panel and movably passes through a guide hole on the small stripper plate. One end of the guide post is fixed on the panel 1, and the other end of the guide post movably penetrates through the front template 3 and the rear template 4 in sequence to guide the front template 3 and the rear template 4 to be matched and demoulded.
