Abstract
The utility model relates to the reinforced die ejector pin of a kind of push rod, comprise countersunk head and push rod, countersunk head and push rod coaxially arrange, and push rod one is built in the lower surface of countersunk head, it is characterized in that: described push rod upper surface is coaxially engaged and a top pressure ring is installed, coaxial installation one elastic component between this top pressure ring and push rod.This die ejector pin is coaxially inlayed a compression ring in push rod upper end, this compression ring adopts spiral way to be screwed in push rod, the impulsive force of push rod is applied on product and by top pressure ring buffering and bears, and has improved thus the impact resistance of push rod, the blastic deformation of push rod to product.
Description
Technical field
The utility model belongs to mould applications, relates to the thimble of mold parts, the reinforced die ejector pin of especially a kind of push rod.
Background technology
Die ejector pin is the instrument for the product after mold moulding is separated on mould, is conventionally axially arranged on patrix or counterdie, and the row's of employing pin mode.Die ejector pin is made up of the countersunk head of integral production and coaxial push rod, and countersunk head and push rod are cylindrical, and the upper end of countersunk head and the lower end of push rod are planar design.When needs are in mould when ejecting product, countersunk head pressurized also promotes push rod and stretches out, and the end face of push rod produces ejecting force to product, thus product is ejected.At present, countersunk head and push rod are the integrally formed structure of unified material, and bulk strength is general; Especially for countersunk head part, this countersunk head is the first force part of mold pressing, and the power that has certain impact, and is very easy to countersunk head blastic deformation, causes thus the length of die ejector pin to change, and causes product to eject deficiency, is not easy discharging.In addition, the lower surface of push rod also has certain impact to product, also easily causes the top trace of product and affects the outward appearance of product.Therefore, overcoming blastic deformation and the push rod bottom blastic deformation to product of countersunk head, is the important guarantee improving the quality of products.
For existing die ejector pin situation, by retrieval, find following relevant patent document:
1, a kind of modified form ejector pin structure of die CN203409934U, comprise thimble body, described thimble body upper surface is provided with multiple grooves, in described groove, be provided with elastic component, evenly be coated with wear-resisting electrostatic layer at the upper surface of thimble body simultaneously, the utility model buffering and good antiskid effect, in the service life of improving thimble, can effectively eliminate electrostatic phenomenon simultaneously.
2, a kind of die ejector pin (CN103395145A), comprise thimble the first shell of column, thimble the second shell of column, thimble the 3rd shell of column, described thimble first shell of column one end is provided with round platform, the other end is connected with thimble the second shell of column, described thimble the second shell of column is connected with thimble the 3rd shell of column, between wherein said thimble the first shell of column and thimble the second shell of column, be provided with transition and connect round platform I, between described thimble the second shell of column and thimble the first shell of column, be provided with transition and connect round platform II.The thimble shell of column that the present invention is reduced successively by three sections of diameters connects to form, reduce the contact area of thimble and installing hole, and by centre bore and bilateral symmetry notch are set on the connection round platform in thimble one end, ensure that thimble installation is fixing reliable, thimble long service life, easy to use, moulded products effectively can be ejected from mould.
Contrast by technical characterictic, above-mentioned two sections of patent documents are not identical with the utility model application, and have equally the problems referred to above.
Utility model content
The purpose of this utility model is to overcome the deficiencies in the prior art part, provides one can ensure that die ejector pin push rod intensity is large, product ejects the reinforced die ejector pin of the reliable push rod in location.
The technical solution of the utility model is:
The reinforced die ejector pin of a kind of push rod, comprise countersunk head and push rod, countersunk head and push rod coaxially arrange, and push rod one is built in the lower surface of countersunk head, it is characterized in that: described push rod upper surface is coaxially engaged and a top pressure ring is installed, coaxial installation one elastic component between this top pressure ring and push rod.
And described top pressure ring engages the structure of installing and is with push rod: be shaped with an outer double-screw bolt in the lower end of top pressure ring, this made internal thread in outer double-screw bolt engagement push rod middle part.
And, coaxially engage a compression ring is installed at the bottom surface of countersunk head, coaxial installation one elastic component between this compression ring and push rod bottom surface.
And described elastic component adopts spring, or adopt rubber blanket.
Advantage of the present utility model and good effect are:
1, this die ejector pin is coaxially inlayed a top pressure ring in push rod upper end, this top pressure ring adopts spiral way to be screwed in push rod, the impulsive force of push rod is applied on product and by top pressure ring buffering and bears, and has improved thus the impact resistance of push rod, the blastic deformation of push rod to product.
2, on the step forming between the top pressure ring that this die ejector pin is installed and push rod, a spring is installed, by effectively shock absorbing power of spring, the skidding of simultaneously avoiding thimble to occur in the time ejecting, ensure that push rod vertically pushes up dress product reliably, make product can be subject to top power straight up, improved effect and the efficiency of discharging.
Brief description of the drawings
Fig. 1 is structural front view of the present utility model;
Fig. 2 is the cross-sectional view of Fig. 1;
Fig. 3 is the A portion structure enlarged diagram of Fig. 2.
Detailed description of the invention
Below by specific embodiment, the utility model is described in further detail, and following examples are descriptive, is not determinate, can not limit protection domain of the present utility model with this.
The reinforced die ejector pin of a kind of push rod, comprises countersunk head 2 and push rod 3, and countersunk head and push rod coaxially arrange, and push rod one is built in the lower surface of countersunk head.
Innovative point of the present utility model is:
Described push rod upper surface is coaxially engaged and a top pressure ring 4 is installed, coaxial installation one elastic component 8 between this top pressure ring and push rod.
Described top pressure ring engages the structure of installing with push rod: be shaped with an outer double-screw bolt 7 in the lower end of top pressure ring, this made internal thread in outer double-screw bolt engagement push rod middle part.
In the present embodiment accompanying drawing, described elastic component adopts spring, also can adopt rubber blanket, and spring housing is contained on the interior made step of push rod outside the pressure ring of top.
In addition, described countersunk head upper surface is coaxially engaged a compression ring 1 is installed, and also adopts the form of outer double-screw bolt 6 and elastic component 5 between this compression ring and countersunk head, and its structure is similar to the installation form of push rod and top pressure ring.
The advantage of the present embodiment is also:
By the compression ring and the top pressure ring that install additional, can adjust by screw thread locate mode the length of die ejector pin, to be applicable to more eurypalynous mould.
