Abstract
The utility model discloses an injection forming mold for an automatic aerator impeller, which comprises a mold core 1 and a mold cavity 4, wherein an impeller body 3 and a cavity 2 connected with an upper flange are arranged on the mold core 1; twelve mold impressions 7 are also evenly arranged at the five equilibrium points of the mold cavity 4. The utility model is characterized in that twelve insert blocks 5 are arranged in the mold impressions 7; the width of the insert blocks 5 nearby the inner circle of the mold cavity 4 is less than that of other insert blocks; the mold impressions formed by blades are arranged between the spare sides of the mold impressions 7. The utility model has the advantages of small volume, low cost, good quality of the impeller, etc., and an impeller body can be formed once. The utility model is an ideal injection forming mold for the automatic aerator impeller.
Description
The utility model relates to a kind of oxygen increasing machine impeller manufacturing installation that is used for aquaculture, specifically relates to the shaping dies of the back taper water lift impeller of aerator.
The manufacturing of the water lift impeller of the aerator back taper of known technology generally is to adopt steel material to be welded through machining and shaping, because impeller is in the water for a long time, what have also is in the seawater, the Exposure to Sunlight aqueous corrosion, working environment is very abominable, therefore very easily corrosion damages and scraps, the weld easy fracture, service life short, maintenance difficult, processed complex is simultaneously because the weight of impeller is big, exist drawbacks such as dynamic efficiency is low, waste electric energy, also have and adopt stainless steel to make, also only overcome the problem of easy-to-rust, and cost is also higher; In order to address the above problem, someone attempts to adopt injection molded, but when making as if the mould that adopts routine, because due to the structure of impeller itself, required mould is bigger, and its weight will be greater than 6 tons, and general lathe can't be processed, and cost is higher, thereby so so far product still can't be applied.
The purpose of this utility model is to provide that a kind of volume is little, cost is low, impeller wheel physical efficiency once-forming, the measured oxygen increasing machine impeller mold for injection molding of impeller matter.
For achieving the above object, the utility model is to adopt following scheme to realize: it comprises the die cavity that blade will be shaped in a core rod, a die cavity and the die cavity, also evenly being provided with plurality of moveable in the Along ent of die cavity inserts, insert and die cavity one side between have blade to be shaped die cavity, insert and die cavity one side for the inclined plane close with the blade lean angle.
Insert and pass die cavity and be fixed on the movable plate.
The width of inserting of the inboard, center of close die cavity is littler than outside width.
After adopting said structure, owing to make the impeller body injection molded by the utility model mould, in light weight, dynamic efficiency is better, also is not afraid of corrosion, long service life, handling ease, cost is also low, and owing to adopted and insert, and will insert by push rod after injection moulding is finished ejects, the wheel rotor body can draw off, need not resemble conventional method and adopt slide block from radially the skidding off of impeller body, thereby the entire die volume is less relatively, general lathe can be finished processing tasks, weight is only about 2 tons according to a preliminary estimate, die cost is also relatively low, and the impeller body quality that goes out by this mold injection is good simultaneously, can satisfy practical requirement fully.
Be described further below in conjunction with drawings and Examples.
Fig. 1 is the sectional structure schematic diagram of the utility model oxygen increasing machine impeller mould;
Local structural representation when Fig. 2 ejects impeller for the utility model oxygen increasing machine impeller die insert;
Fig. 3 is the planar structure schematic diagram of the utility model oxygen increasing machine impeller mould cavity.
As shown in Figure 1, mould of the present utility model comprises a core rod 1, one die cavity 4, as Fig. 3, die cavity 4 is connected to 1 of core rod and is connected guide post 8, have on the core rod 1 impeller body 3 with on connect the hole 2 that is connected of dish, as shown in Figure 3, also evenly be provided with 12 die cavitys 7 in the Along ent of die cavity 3, be provided with 12 in the die cavity 7 and insert 5, insert 5 near die cavity 7 one sides, the width of 5 parts of inserting in the interior center of circle of close die cavity 4 is littler than its elsewhere, the die cavity that will be shaped for blade between the vacant opposite side of die cavity 7, inserting 5 has the inclined plane similar to the blade lean angle with die cavity 7 one sides, inserts 5 to be fixed on the movable plate 6, this plate 6 can keep the 5 same moved further of inserting, driving when movable plate 6 moves inserts 5 ejects, and as shown in Figure 2,5 impeller bodies 2 with injection molded of inserting eject, rotate the direction of impeller body 2, can from mould, draw off.
