Embodiment Construction
[0019] Such as Figure 1 to Figure 4 As shown, the present invention includes: upper die 1, lower die 2, guide hole 11, mold core 14, discharge port 23, choke bridge 12, suspension bridge 13, radiating hole choke table 22 and radiating hole partition blocking flow Platform 21, during production, the upper mold 1 and the lower mold 2 are connected by screws, and the mold core 14 is arranged in the middle part of the upper mold 1, because the cross section of the product 3 is circular, so the mold core is circular, and A plurality of guide holes 11 are evenly distributed around the core, the guide holes are feeding holes, and a flow blocking bridge 12 is arranged between the guide holes and the guide holes. plate (splitter bridge), and the main function is to block the flow, and the bottom of the flow block bridge 12 is facing the spacer part 31 of the production product, see Figure 9 As shown, because the thickness and width of the mold cavity are larger than other places, th...

The invention relates to a new energy automobile motor shell die which comprises an upper die, a lower die, guide holes, a die core and a discharging hole. The upper die and the lower die are connected through screws. The new energy automobile motor shell die is characterized in that the new energy automobile motor shell die further comprises flow choking bridges, hanging bridges, cooling hole flow choking bosses and cooling hole separation block flow choking bosses, the flow choking bridges are arranged above a cooling hole separation block die cavity, and the flow choking bridges and the die core are connected as a whole; the cooling hole flow choking bosses and the cooling hole separation block flow choking bosses are arranged above the periphery of a die core cavity of the lower die, and the cooling hole flow choking bosses and the cooling hole separation block flow choking bosses are arranged in a spaced mode and are evenly distributed around the die core; each hanging bridge is arranged on the lower portion of each guide hole, a small injecting head is arranged at the bottom end of each hanging bridge, the hanging bridges and the upper ends of the small injecting heads are connected as a whole, flow guide channels are formed inside and outside the hanging bridges, and the two sides of the hanging bridges and the flow choking bridges are connected as a whole. Due to the fact that the new energy automobile motor shell die is provided with the flow choking bridges, the flowing speed of aluminum materials in the die cavity at the positions of product separation blocks is reduced remarkably, balance of the overall speed of the aluminum materials for entering the die cavity is achieved, quality of product is improved, and generation of waste products is prevented.
Description
technical field [0001] The invention relates to a profile mold, in particular to a new energy automobile motor housing mold. Background technique [0002] The traditional automobile motor housing is made of iron. With the need of energy saving, there is now an aluminum profile automobile motor housing. The mold design is unreasonable, the production is not stable enough, the scrap rate is high, and the production efficiency is low. Contents of the invention [0003] The object of the present invention is to provide a new energy automobile motor shell mold for the above problems. [0004] To achieve the above object, the present invention adopts the following technical solutions: [0005] A new energy automobile motor shell mold, including: an upper mold, a lower mold, a guide hole, a mold core and a discharge port, the upper mold and the lower mold are connected by screws, and it is characterized in that it also includes a flow blocking bridge and a suspension bridge , ...
