Abstract
The utility model provides a runner insert, which comprises an insert body; the insert body is cylindrical, and the top of the insert body is provided with a mounting seat; the front side surface of the insert body is provided with a feed inlet, the feed inlet is communicated with a first flow passage, and the first flow passage is connected with two second flow passages; the first flow channel and the second flow channel are both arc-shaped flow channels; and the two second flow passages are respectively communicated with discharge ports positioned on the left side surface and the right side surface of the insert body. The runner mold insert passes through the mount pad to be fixed in double-deck runner system, and the hot melt adhesive passes through the runner mold insert feed inlet and flows in at the first layer, gets into the second floor through first runner and second runner, flows out from the discharge gate, and the inside runner of a runner and second runner all adopts the fillet, has solved the dead angle problem that produces in the double-deck runner, can not appear bad problems such as product heterochrosis, black line, has improved the efficiency of moulding plastics.
Description
Technical Field
The utility model relates to the field of hot runners, in particular to a runner insert.
Background
Hot Runner (Hot Runner Systems) is a system of heating assemblies used in injection molds to inject molten plastic pellets into the mold cavity. The hot runner mold is a new structure in which the runner and the runner of the conventional mold or the three-plate mold are heated, and the runner do not need to be taken out for each molding.
The needle valve type hot runner saves materials, and the plastic part has beautiful surface, compact internal quality and high strength.
In the prior art, a runner plate in a hot runner system is processed by adopting direct drilling and matching with a plug to form a runner, so that the turning part of the runner is basically a right-angle curve and is not smooth, the problems of different colors, black stripes and the like of a product can be caused, and the injection molding effect is poor.
SUMMERY OF THE UTILITY MODEL
In view of this, the technical problem to be solved by the present invention is to provide a runner insert, which can improve the injection molding effect.
The technical scheme of the utility model is realized as follows:
the utility model provides a runner insert, which comprises an insert body;
the insert body is cylindrical, and the top of the insert body is provided with a mounting seat;
the front side surface of the insert body is provided with a feed inlet, the feed inlet is communicated with a first flow passage, and the first flow passage is connected with two second flow passages; the first flow channel and the second flow channel are both arc-shaped flow channels;
and the two second flow passages are respectively communicated with discharge ports positioned on the left side surface and the right side surface of the insert body.
Preferably, the mounting seat is provided with a groove.
Preferably, the discharge hole is positioned behind the feed inlet.
Preferably, the diameter of the first flow channel is larger than the diameters of the two second flow channels.
According to the runner insert, the runner insert is fixed in a double-layer runner system through the mounting base, hot melt adhesive flows in the first layer through the feed port of the runner insert, enters the second layer through the first runner and the second runner, and flows out of the discharge port, and runners in the first runner and the second runner are all rounded, so that the problem of dead corners generated in the double-layer runner is solved, the problems of different colors, black stripes and the like of products are avoided, and the injection molding efficiency is improved.
Drawings
Fig. 1 is a schematic structural diagram of a runner insert according to an embodiment of the present invention;
fig. 2 is a front view of a runner insert according to an embodiment of the present invention.
Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As shown in fig. 1 and 2, the present invention provides a runner insert, comprising an insert body 1;
the insert body 1 is cylindrical, and the top of the insert body is provided with a mounting seat 2;
a feed inlet 3 is formed in the front side face of the insert body 1, the feed inlet 3 is communicated with a first flow passage 4, and the first flow passage 4 is connected with two second flow passages 5; the first flow channel 4 and the second flow channel 5 are both arc-shaped flow channels;
the two second flow passages are respectively communicated with discharge ports 6 positioned on the left side surface and the right side surface of the insert body 1.
Therefore, according to the runner insert provided by the utility model, the runner insert is fixed in a double-layer runner system through the mounting base, the hot melt adhesive flows in the first layer through the feed inlet of the runner insert, enters the second layer through the first runner and the second runner, and flows out from the discharge outlet, and the runners in the first runner and the second runner are all rounded, so that the problem of dead angles generated in the double-layer runner is solved, the problems of different colors, black stripes and the like of products cannot occur, and the injection molding efficiency is improved.
In a preferred embodiment of the utility model, the mounting seat is provided with a groove 7.
In this application, the runner insert can be fixed in the hot runner system through recess 7.
In a preferred embodiment of the present invention, the discharge port is located behind the feed port.
During the use, the feed inlet of runner mold insert is located the first layer of hot runner, and the discharge gate is located the second layer of hot runner, accomplishes the transport of hot melt adhesive.
In a preferred embodiment of the utility model, the diameter of the first flow channel is larger than the diameter of the two second flow channels.
Because the second runner is two, the diameter of first runner is greater than the diameter of two second runners, can promote conveying efficiency.
According to the runner insert, the runner insert is fixed in a double-layer runner system through the mounting base, hot melt adhesive flows in the first layer through the feed port of the runner insert, enters the second layer through the first runner and the second runner, and flows out of the discharge port, and runners in the first runner and the second runner are all rounded, so that the problem of dead corners generated in the double-layer runner is solved, the problems of different colors, black stripes and the like of products are avoided, and the injection molding efficiency is improved.
Finally, it is to be noted that: the above description is only a preferred embodiment of the present invention, and is only used to illustrate the technical solutions of the present invention, and not to limit the protection scope of the present invention. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention shall fall within the protection scope of the present invention.
