Detailed Description

The invention will be further described with reference to the following examples.

The utility model discloses a car console skeleton injection mold's embodiment, as shown in fig. 3, including cope match-plate pattern 3, lower bolster (not shown) and the runner plate (not shown) that is located 3 tops of cope match-plate pattern, be equipped with the die cavity that is used for the shaping skeleton between cope match-plate pattern 3 and the lower bolster, lower bolster still rigid coupling has the mold insert 4 that is located the die cavity and is used for the shaping skeleton internal bucket. It should be noted that, in order to facilitate understanding of the mold improvement point of the present embodiment, fig. 3 only shows the upper mold plate 3 and the insert 4, and the lower mold plate and the runner plate may both adopt the lower mold plate and the runner plate of a conventional sub-instrument panel framework injection mold, and the structures and the working principles of the lower mold plate and the runner plate are easily known to those skilled in the art.

In this embodiment, the runner plate is provided with a pouring gate located in the middle of the top surface thereof and four runner ports located in the bottom surface thereof, as an improvement, the top surface of the upper die plate 3 is provided with four hot nozzle mounting positions 31 arranged at intervals, each hot nozzle mounting position 31 is communicated with the corresponding runner port, each hot nozzle mounting position 31 is used for mounting the corresponding hot nozzle assembly 7, please see fig. 3, the left-to-right direction of fig. 3 is the length direction of the framework, the hot nozzle mounting position 31 located at the leftmost end of fig. 3 is the hot nozzle mounting position 31 corresponding to the first step surface 11 of the cavity (framework), and the hot nozzle mounting positions 31 located at the second, third and fourth are the hot nozzle mounting positions 31 corresponding to the second step surface 12 of the cavity (framework). Through the sprue gate setting with the runner plate in its middle part, combine figure 4, the material is advanced to the sprue gate of runner plate, then the material flows in the hot mouth subassembly 7 that corresponds in proper order after the reposition of redundant personnel of runner plate, because the hot mouth subassembly 7 that corresponds with first step face 11 is located the first side of the left side, consequently, the material can flow just can pour into a mould first step face 11 part after the certain stroke, can effectively alleviate the problem that hot mouth subassembly 7 that first step face 11 goes out leads to the sun facula because of the high temperature.

Referring to the schematic diagram of the skeleton waterway structure of fig. 5, for convenience of understanding, only two hot nozzle assemblies 7 are shown above the skeleton, the hot nozzle assembly 7 at the leftmost end corresponds to the first step surface 11 of the skeleton, and the hot nozzle assembly 7 at the rightmost end corresponds to the second step surface 12 of the skeleton. In the improvement, a hot nozzle cooling water path 5 is arranged around the outer periphery of the bottom end of the hot nozzle mounting position 31 inside the upper template 3, and the hot nozzle cooling water path 5 is mainly arranged around the outer periphery of a sprue gate of the hot nozzle assembly 7 and mainly cools the joint of the hot nozzle assembly 7 and the cavity. Combine fig. 6, insert 4 inboard is equipped with the spiral cooling water route 6 that is the heliciform setting on the direction of height, and spiral cooling water route 6 mainly cools off the interior fill department of skeleton, guarantees that the upside and the downside of first step face 11 all are provided with the cooling water route.
