Abstract
The utility model discloses a mold for casting a universal joint blank. The mold comprises an upper concave mold (1) and a lower concave mold (2), wherein a through hole (3) is formed in the center of a bottom surface of the upper concave mold (1); a groove (4) is formed in an edge of the through hole (3); a through hole (7) is formed in the center of the top of the lower concave mold (2); a groove (5) is formed in an edge of the through hole (7); the groove (5) and the groove (4) are assembled to form an inner cavity; the shape of the inner cavity is as the same as an outer contour shape of a product to be processed; one end of the groove (5) is connected with the through hole (7). According to the design of the mold, the equipment cost is reduced in the process of producing the universal joint, the waste gas emission and energy consumption are reduced, the environmental protection is promoted, and the produced universal joint is high in precision.
Description
Technical field
The utility model relates to a kind of processing mold, particularly a kind of mould of casting universal joint blank.
Background technology
Universal joint is to realize the parts that varied angle power transmits, and for changing the position of transmission axis direction, is the joint component of the universal driving device of automobile driving system, and universal joint and power transmission shaft combination, form card gear together.At present, the method with forge hot is generally produced in the processing of market upper cardan, under 900 ℃ of-950 ℃ of high temperature, forge, this method needs high temperature furnace, produces a large amount of waste gas, affects integrated environment, it is a kind of mode of production of high pollution high energy consumption, and the dimensional accuracy of adopting the universal joint of producing is in this way poor, surface is also more coarse, and productivity ratio is not high yet.Due to corresponding firing equipment of needs etc., production cost also improves accordingly.
Summary of the invention
The purpose of this utility model is to provide in order to solve above-mentioned the deficiencies in the prior art that a kind of precision is higher, cost is lower, the mould of the casting of automobile universal joint blank of environmental protection.
To achieve these goals, a kind of mould of casting universal joint blank that the utility model is designed, comprise upper cavity die, lower cavity die, place of described upper cavity die bottom center is provided with through hole, described through hole edge is provided with groove, described lower cavity die top center place is provided with through hole, and through hole edge is provided with groove, after described groove and groove assembling, is formed with inner chamber, described cavity shape is identical with the outer contour shape of processed product, and one end of groove is connected with through hole.
Further, the other end of groove is provided with two parallel exhaust grooves and is connected with the external world of lower cavity die, and the degree of depth of described exhaust groove is less than the degree of depth of groove.
Further, the degree of depth of groove is less than the thickness of upper cavity die, and the degree of depth of groove is less than the thickness of lower cavity die.
Further, described through hole and through hole cross section are circular, and through hole and through hole are connected.
Further, described groove and groove number are respectively four, and the number of exhaust groove is eight.
The utility model compared with prior art, there is following beneficial effect: 1, adopt this extrusion die, directly cooling reinforcing bar is processed, do not need high temperature furnace, corresponding production cost reduces, there is no the discharge of waste gas and the consumption of a large amount of heat energy simultaneously, be a kind of mode of energy-conserving and environment-protective, and allow employee have a better production environment yet.2, owing to directly carrying out cold extrusion, and the exhaust groove of lower cavity die, can make hail contact more fully die cavity, the precision of the universal joint of production is higher, and surface roughness is also better.
