Description
Technical Field
The utility model belongs to a slot wedge forming die specifically is a slot wedge mould for motor.
Background
The slot wedge has been widely used in a motor, and various processes are required to manufacture the slot wedge, and a mold is one of important parts in manufacturing the slot wedge.
As shown in fig. 1, the conventional slot wedge mold mainly includes an upper mold and a lower mold, the lower mold is provided with a cavity, and the upper mold is provided with a male mold matched with the cavity. The processes of die assembly, die release and workpiece taking are complex during manufacturing and operation of the slot wedge die, and particularly the related dimensional accuracy requirement of the matched part of the male die and the cavity is high, the processing difficulty is high, and the die is difficult to clean; secondly, the slot wedge mould can not be formed once when pressing the slot wedge, needs secondary processing slot wedge length, and the surface of the mould is easy to be damaged by the matching part of the convex mould and the cavity.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the slot wedge die overcomes the defects and is simple in structure, convenient to operate, low in cost and capable of guaranteeing the precision and the size of the slot wedge.
The utility model adopts the technical proposal that: a slot wedge die comprises an upper die and a lower die, wherein the upper surface of the lower die is provided with a plurality of first grooves, and two sides of each first groove are provided with second grooves; third grooves communicated with the first grooves are further formed in the two sides of the lower die, and baffles are arranged in the third grooves; the lower surface of going up the mould is equipped with the fourth recess that corresponds with first recess, first recess and fourth recess form the cavity of suppression slot wedge jointly.
In the above scheme, when the slot wedge is pressed, the blank is placed in the first groove, the baffle is placed in the third groove, then the upper die is closed, the blank is formed in the cavity formed by the first groove and the fourth groove together, and if the blank overflows in the pressing process, the overflowing blank flows into the second groove. Because the whole die does not have a convex die, the surface of the die cannot be pulled, and the size and the precision of the slot wedge can be ensured due to the arrangement of the baffle.
Preferably, the two ends of the third groove are open, the baffle is placed in the third groove, and the two ends of the baffle extend out of the third groove.
The arrangement is convenient for processing and cleaning the die.
Preferably, the lower part of one side of the third groove, which is far away from the first groove, is inclined to serve as a guide of the baffle.
Preferably, the height of the baffle is greater than the depth of the third groove, and the upper die is arranged between the two baffles and abutted to the baffles.
Through the arrangement, the baffle can be used as a guide structure for placing the upper die.
Preferably, the upper surface of lower mould still is equipped with the locating hole, the lower surface of last mould is equipped with the reference column with locating hole complex.
Preferably, a handle is further arranged on the side surface of the upper die.
The utility model has the advantages that: the slot wedge mould of the utility model has short manufacturing period, long service life, low cost, small volume, light weight and convenient operation; the precision size of the slot wedge can be effectively ensured, and compared with the conventional die, the production efficiency is high, and the labor intensity is low; the male die is not arranged, the adhesive force between the upper die and the lower die is small, the demoulding is easy, and the surface of the die cannot be damaged.

Detailed Description
The invention will be further explained with reference to the drawings and the specific embodiments.
As shown in fig. 2 to 8, a slot wedge mold comprises an upper mold 1 and a lower mold 2, wherein the upper surface of the lower mold 2 is provided with a plurality of first grooves 21, and two sides of each first groove 21 are provided with second grooves 22; a third groove 23 communicated with the first groove 21 is further formed in the two sides of the lower die 2, and a baffle 3 is placed in the third groove 23; the upper surface of the upper die 1 is provided with a fourth groove 11 corresponding to the first groove 21, and the fourth groove 11 and the first groove 21 together form a cavity for pressing the slot wedge.
When the slot wedge is pressed, the blank for manufacturing the slot wedge is placed in the first groove 21, and because the blank may overflow when the blank is pressed, the second grooves 22 are arranged at two sides of the first groove and are used for storing the overflowing blank; meanwhile, in order to ensure the size and the precision of the formed slot wedge, third grooves 23 for placing the baffle plates 3 are arranged at two ends of the first grooves 21, the height of the baffle plates 3 is greater than the depth of the third grooves 23, and therefore the baffle plates 3 can also play a role in guiding.
In this embodiment, handles 13 integrally provided with the upper die 1 are provided on both sides of the upper die 1, the lower surface of the upper die 1 is further provided with a plurality of guide posts 12, and the upper surface of the lower die 2 is provided with positioning holes 24 engaged with the guide posts 12. When the upper die 1 and the lower die 2 are closed, the guide posts 12 and the positioning holes 24 play a role in guiding.
In this embodiment, the first groove 21 and the second groove 22 are arranged in parallel and both ends thereof are open; both ends of the third groove 23 and the fourth groove 11 are open, and both ends of the baffle 3 extend out of both ends of the third groove 23. The two ends of the 4 grooves are provided with openings, so that the processing and cleaning of the die are facilitated.
In this embodiment, due to the requirement of the wedge shape, the cross section of the first groove 21 is trapezoidal, the cross section of the second groove 22 is semicircular, and the groove depth of the third groove 23 is greater than that of the first groove 21, so as to ensure the dimensional accuracy of the two ends of the wedge.
In this embodiment, the lower portion of the third groove 23 away from the first groove is inclined to facilitate positioning of the baffle 3, and correspondingly, the lower portion of the baffle 3 is also inclined.
