Embodiment Construction
[0051] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.
[0052] In the description of the present invention, it should be noted that unless otherwise specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection or a detachable connection. Connected, or integrally connected; it may be mechanically connected or electrically connected; it may be directly connected or indirectly connected through an intermediary, and it may be the internal communication of two components. "First", "second", "third" and "fourth" do not represent any sequence relationship, but are only distinguished for convenience of description. Those of ordinary skil...

The invention relates to the technical field of molds, in particular to a hot sprue, a hot runner injection mold and a pouring method thereof. The hot sprue comprises a front hot sprue core and a rear hot sprue core, and the front hot sprue core and the rear hot sprue core are oppositely arranged; the front hot sprue core is provided with a through hot runner; the first hot pouring end of the front hot sprue core is provided with a concave first groove, and the groove wall of the first groove, the end face of the first hot pouring end and the outer side face of the first hot pouring end are connected to form a first glue sealing wall; and a second hot pouring end of the rear hot sprue core is provided with a concave second groove, and the groove wall of the second groove, the end face of the second hot pouring end and the outer side face of the second hot pouring end are connected to form a second glue sealing wall. In order to separate a workpiece from hot melt glue between the front hot sprue core and the rear hot sprue core, the front hot sprue core and the rear hot sprue core do opposite motion towards one or two of the lower portion and the middle portion, and the first glue sealing wall and / or the second glue sealing wall can separate and cut the workpiece from the hot melt glue in the hot sprue during opposite motion. Operation is facilitated, and the structure is simple.
Description
technical field [0001] The invention relates to the field of mold technology, in particular to a hot sprue, a hot runner injection mold and a pouring method thereof. Background technique [0002] by figure 1 The rectangular hollow part 01 shown is taken as an example, and the part is molded by injection molding with an existing mold, usually using figure 2 In the point feeding shown, the melt enters the mold cavity from the feeding point 02, flows along both sides, and will meet at the filling end position, thereby forming the joint line 03. The bonding line will not only reduce the structural strength of the part, but also be an appearance defect, especially when using spray-free materials or colored materials. [0003] This defect can be improved by filling the hole in the middle with the same plastic material as the part, and then removing the filling plastic in the middle after molding, such as image 3 As shown, the material to fill the hollow part 01 can be regarde...
