Description
Technical Field
The utility model relates to a mould field, especially an automobile engine tappet body guarantee axiality mold processing.
Background
The fuel injection system is a key part of an automobile engine, the quality of the fuel injection system directly affects the running speed of an automobile, the fuel consumption, the environmental pollution and the like, and the tappet body is used as a key part of the fuel injection system of the lorry, so that the market demand of the tappet body is increasingly large. Although the parts are not large, the appearance structure is complex, and the size design precision is high. After the tappet forges a blank, the finished product is processed by drilling, milling and grinding without one-time forming equipment and a die. The method has the biggest problems that the product consistency cannot be ensured and the quality is unstable due to the small product, high fineness, large forging process error and the influence of uncertain factors such as later-stage processing personnel, equipment and the like.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to overcome prior art's shortcoming, provide an automobile engine tappet body guarantees axiality mold processing.
The purpose of the utility model is realized through the following technical scheme: the mold comprises a mold shell and a mold core, wherein a core cavity is formed in the mold shell, the mold core is arranged in the core cavity, a discharge hole is formed in the middle of the mold shell and communicated with the mold core, and a stripping mechanism is further arranged on the mold shell.
Specifically, the stripping mechanism comprises an ejector rod, a spring and a limiting bolt, the upper level of the formwork is provided with a mounting hole, the ejector rod is arranged in the mounting hole, one end of the ejector rod is connected with the spring, and the limiting bolt is in threaded connection with the spring in the mounting hole and pressed between the limiting bolt and the ejector rod.
Specifically, the ejector pin be T style of calligraphy, the front end of mounting hole is T type hole and ejector pin cooperation installation, the mounting hole intercommunication discharge opening, the one end of ejector pin extends to in the discharge opening.
Specifically, the front end of the ejector rod is provided with an inclination angle.
Specifically, the stripping mechanism is symmetrically provided with two stripping mechanisms.
The utility model has the advantages of it is following:
The device does not need to consider the inherent potential factors that the precision of equipment, the flow direction of metal materials and the like can not meet the product quality, the prefabricated blank can generate longitudinal flow under the interaction force of the inner die and the outer die according to the set flow direction by using the inner die core rod, so that the requirement of high-quality and high-standard equal-wall-thickness quality can be obtained, and the material can be automatically removed, so that the processing can be continuously carried out at the same time, the processing efficiency is improved, and the manpower waste is reduced.

FIG. 2 is a diagram A illustrating the usage status of the present invention;
FIG. 3 is a diagram of the usage state of the present invention;
in the figure: 1-inner mold core rod, 2-mold core, 3-ejector rod, 4-spring, 5-limit bolt, 6-blank and 7-mold shell.
Detailed Description
the invention will be further described with reference to the accompanying drawings, but the scope of the invention is not limited to the following description.
as shown in fig. 1 to 3, a mold for processing a tappet body of an automobile engine to ensure coaxiality comprises a mold shell 7 and a mold core 2, wherein a core cavity is arranged on the mold shell 7, the mold core 2 is arranged in the core cavity, a discharge hole 8 is arranged in the middle of the mold shell 7, the discharge hole 8 is communicated with the mold core 2, a stripping mechanism is further arranged on the mold shell 7, the stripping mechanism comprises a push rod 3, a spring 4 and a limit bolt 5, a mounting hole is horizontally arranged on the mold shell 7, the push rod 3 is arranged in the mounting hole, one end of the push rod 3 is connected with the spring 4, the limit bolt 5 is in threaded connection with the mounting hole to press the spring 4 between the limit bolt 5 and the push rod 3, the push rod 3 is T-shaped, the front end of the mounting hole is a T-shaped hole, the push rod 3 is installed in a matched manner, the mounting hole is communicated with the discharge; during cold heading, under the interaction force of an inner die and an outer die, the inner die core rod 1 presses the blank 6 downwards, the blank 6 is punched and formed after passing through the inner cavity of the die core 2, the inner die core rod 1 is pressed downwards after forming, the formed blank 6 enters the discharge hole 8, when the blank 6 contacts the ejector rod 3, the blank 6 is pressed by the ejector rod 3 to retract into the mounting hole in the descending process of the blank 6 due to the fact that the front end of the ejector rod 3 is provided with an inclination angle similar to a wedge, the blank 6 extrudes the ejector rod 3 to retract into the mounting hole, the ejector rod 3 compresses the spring 4 when retracting into the mounting hole, the blank 6 continues to descend until the top of the blank 6 passes through the ejector rod 3, at the moment, the restoring force of the spring 4 automatically ejects the ejector rod 3 to buckle the material, then the inner die core rod 1 ascends, the blank 6 can be separated from the inner die core rod 1, the automatic stripping effect is achieved, and the blank 6 in the discharge hole 8 can be, the die can be used for continuous cold heading processing, automatic stripping is realized, the coaxiality of processed workpieces is high, and one-step forming is realized.
Furthermore, the front end of the ejector rod 3 is provided with an inclination angle.
Furthermore, the stripping mechanisms are symmetrically provided with two stripping mechanisms.
The foregoing is merely a preferred embodiment of the invention and is not intended to limit the invention in any way. The technical solutions of the present invention can be used by anyone skilled in the art to make many possible variations and modifications to the technical solution of the present invention, or to modify equivalent embodiments with equivalent variations, without departing from the scope of the technical solution of the present invention. Therefore, any modification, equivalent change and modification of the above embodiments according to the present invention are all within the protection scope of the present invention.
