The utility model provides a technical scheme that its technical problem adopted is: a shortened two-plate sprue bushing structure of a plastic mold is improved in that: comprises a mould blank, a mould core and a squirt nozzle;
the lower surface of the mould blank is provided with an accommodating groove for accommodating the mould core, the mould blank is also provided with a step through hole for accommodating the squirt nozzle, the mould core is correspondingly provided with a first through hole, and the tail end of the squirt nozzle penetrates out of the first through hole of the mould core;
a bulge is arranged on the bottom surface of the accommodating groove of the mold blank, a groove is arranged at a corresponding position on the mold core, and the bulge of the mold blank is positioned in the groove of the mold core; the step through hole penetrates out of the bulge of the die blank, and the first through hole is located in the groove.
In the structure, a chamfer is arranged at the opening of the step through hole of the die blank.
In the above structure, the lower surface of the mold core is provided with a water gap communicated with the squirt nozzle.
In the structure, the longitudinal section of the bulge of the mold blank is circular, and the diameter of the circular bulge is gradually reduced from the bottom surface of the accommodating groove to the mold core.
The utility model has the advantages that: the utility model discloses a shorten two board mould purt mouth structures of plastic mould through protruding on the mould embryo, the groove structure design on the mold core, has shortened the purt mouth and has moulded plastics runner material length promptly, has improved production stability, shortens the shaping cycle, reduces mould cooling time to still shorten the die sinking distance, improved shaping efficiency.

Detailed Description
The present invention will be further explained with reference to the drawings and examples.
The conception, the specific structure, and the technical effects produced by the present invention will be clearly and completely described below in conjunction with the embodiments and the accompanying drawings to fully understand the objects, the features, and the effects of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all embodiments, and other embodiments obtained by those skilled in the art without inventive labor based on the embodiments of the present invention all belong to the protection scope of the present invention. In addition, all the connection/connection relations referred to in the patent do not mean that the components are directly connected, but mean that a better connection structure can be formed by adding or reducing connection auxiliary components according to specific implementation conditions. The utility model discloses each technical feature in the creation can the interactive combination under the prerequisite that does not contradict conflict each other.
Referring to fig. 1 to 3, the present invention discloses a shortened two-plate mold sprue bush structure for a plastic mold, in this embodiment, the structure includes a mold blank 10, a mold core 20 and a sprue bush 30, wherein an accommodating groove 101 for accommodating the mold core 20 is provided on a lower surface of the mold blank 10, the mold core 20 is disposed in the accommodating groove 101 of the mold blank 10, an upper surface of the mold core 20 is attached to a bottom surface of the accommodating groove 101, the mold blank 10 is further provided with a step through hole 101 for accommodating the sprue bush 30, and an opening of the step through hole 101 is provided with a chamfer for facilitating injection molding; the mold core 20 is correspondingly provided with a first through hole 201, the end of the squirt nozzle 30 penetrates out of the first through hole 201 of the mold core 20, and the lower surface of the mold core 20 is provided with a water gap 40 communicated with the squirt nozzle 30.
Further, as shown in fig. 1 and fig. 3, a protrusion 102 is disposed on a bottom surface of the accommodating groove 101 of the mold blank 10, a groove 202 is disposed at a corresponding position on the mold core 20, and the protrusion 102 of the mold blank 10 is located in the groove 202 of the mold core 20; moreover, the step through hole 101 penetrates out of the protrusion 102 of the mold blank 10, and the first through hole 201 is located in the groove 202. In this embodiment, the longitudinal section of the protrusion 102 of the mold blank 10 is circular, and the diameter of the circle gradually decreases from the bottom surface of the receiving groove 101 to the mold core 20, so that by the design of the structure, when the mold blank 10 is assembled with the mold core 20, the protrusion 102 and the groove 202 are matched to play a guiding role, thereby facilitating the assembly of the mold blank 10 and the mold core 20.
