Abstract
The utility model relates to a kind of stamping die metal thimble, comprise needle point, thimble rod and thimble seat, the outer circumferential walls of thimble rod is provided with several annular grooves, needle point is conical structure, needle point connects the front end being arranged on thimble rod, thimble seat connects the rear end being arranged on thimble rod, and needle point, thimble rod and thimble seat are structure as a whole, and the outer surface of needle point, thimble rod and thimble seat is coated with anti oxidation layer.Stamping die metal roof needle construction of the present utility model is simple, easily manufactured, compared with prior art, owing to being provided with several annular grooves in outer circumferential walls, reduces frictional resistance, not easy to wear, has better result of use.
Description
Technical field
The utility model relates to the technical field of mould, especially a kind of stamping die metal thimble.
Background technology
Die ejector pin is for goods shaping in ejection die, traditional die ejector pin is by cylindrical, top shank, form with the cylindrical thimble countersunk head of cylindrical, top shank one, this cylindrical thimble countersunk head is positioned at one end of cylindrical, top shank, and cylindrical thimble is the cylinder that an external diameter is equal, the die ejector pin of this structure is installed in a mold in die ejector pin installing hole, when needs eject moulded products, the thimble rod of die ejector pin stretches out in installing hole, there is following defect in the die ejector pin of this structure, whole thimble rod contacts with installing hole inner surface, when thimble moves back and forth, rub with installing hole inner surface, comparison of resistance is large, thus cause thimble rod outer surface to grind flower, thimble rod outer surface is made to become coarse, substantially reduce the service life of die ejector pin, and contact completely with installing hole inner surface due to thimble rod, need shaping goods to be ejected by larger thrust, use inconvenience.
Utility model content
The technical problems to be solved in the utility model is: for solving above-mentioned Problems existing, provide one to eject effective, the stamping die metal thimble that contact area is little.
The utility model solves the technical scheme that its technical problem adopts: a kind of stamping die metal thimble, comprises needle point, thimble rod and thimble seat, the outer circumferential walls of thimble rod is provided with several annular grooves.
Further, needle point is conical structure, and needle point connects the front end being arranged on thimble rod, and thimble seat connects the rear end being arranged on thimble rod.
Further, needle point, thimble rod and thimble seat are structure as a whole, and the outer surface of needle point, thimble rod and thimble seat is coated with anti oxidation layer, can effectively prevent from getting rusty.
The beneficial effects of the utility model are: stamping die metal roof needle construction of the present utility model is simple, easily manufactured, compared with prior art, owing to being provided with several annular grooves in outer circumferential walls, reduce frictional resistance, not easy to wear, there is better result of use.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model.
1. needle points, 2. thimble rod, 3. thimble seat, 4. annular groove in figure.
Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
The metal thimble of stamping die as shown in Figure 1, comprise needle point 1, thimble rod 2 and thimble seat 3, the outer circumferential walls of thimble rod 2 is provided with several annular grooves 4, wait in use, lubricating oil is stained with in annular groove 4, contact area can be reduced, reduce wear, needle point 1 is conical structure, convenient installation, needle point 1 connects the front end being arranged on thimble rod 2, thimble seat 3 connects the rear end being arranged on thimble rod 2, needle point 1, thimble rod 2 and thimble seat 3 are structure as a whole, needle point 1, the outer surface of thimble rod 2 and thimble seat 3 is coated with anti oxidation layer, extend service life.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
