Abstract
The utility model relates to a kind of wide top rod mold thimble, comprise countersunk head and push rod, countersunk head and push rod coaxially arrange, push rod one is built in the lower surface of countersunk head, it is characterized in that: the bottom of described push rod is coaxially radially shaped with evagination round platform, the outer section middle part of this lower outside dome platform is coaxially fixed with cushion pad.This die ejector pin adds cushion pad in the outer face of push rod; can effectively cushion the impulsive force between push rod and product; ensure that push rod vertically pushes up dress product; make product can be subject to top power straight up; effect and the efficiency of discharging are improved, the wearing and tearing of also having protected mould to avoid repeatedly ejecting simultaneously.
Description
Technical field
The utility model belongs to mould applications, relates to the thimble of mold parts, especially a kind of wide top rod mold thimble.
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.Countersunk head is accepted downforce or the upper top power of mould, and the upper plane of its countersunk head is less, therefore also less with the contact area of mould; And the made pilot hole of push rod below countersunk head and mould is gapped, in the time that this gap is larger, often cause countersunk head to be tilted to lower stress, the pilot hole of mould is received compared with galling, in the time that wearing and tearing are larger, will make push rod yaw tilt ground ejecting product, produce waste product or discharging and have some setbacks, often need the discharging repeatedly of secondary and even three times, four times, cause the decline of productivity ratio and the wearing and tearing to mould.
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 a kind of and ensures that die ejector pin ejects reliably, avoids the crooked wide top rod mold thimble of deflection.
The technical solution of the utility model is:
A kind of wide top rod mold thimble, 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: the bottom of described push rod is coaxially radially shaped with evagination round platform, the outer section middle part of this lower outside dome platform is coaxially fixed with cushion pad.
And the top of described countersunk head is coaxially radially shaped with a upper outside dome platform, the middle part, outer face of this upper outside dome platform is coaxially fixed with cushion pad on.
Advantage of the present utility model and good effect are:
1, this die ejector pin strengthens the outer face of push rod, has improved the area of push rod and product depanning, has improved thus ejecting force, has realized the steady depanning of product.
2, this die ejector pin adds cushion pad in the outer face of push rod; can effectively cushion the impulsive force between push rod and product; ensure that push rod vertically pushes up dress product; make product can be subject to top power straight up; effect and the efficiency of discharging are improved, the wearing and tearing of also having protected mould to avoid repeatedly ejecting simultaneously.

Fig. 2 is the top view of Fig. 1;
Fig. 3 is the upward view of Fig. 1.
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.
A kind of wide top rod mold thimble, comprises countersunk head 3 and push rod 4, 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:
The bottom of described push rod is coaxially radially shaped with evagination round platform 5, and the outer section middle part of this lower outside dome platform is coaxially fixed with cushion pad 6, and this cushion pad is rubber blanket and is packed on push rod by vulcanization.
The top of described countersunk head is coaxially radially shaped with a upper outside dome platform 1, and the middle part, outer face of this upper outside dome platform is coaxially fixed with cushion pad 2 on, and this cushion pad is rubber blanket and is packed on countersunk head by vulcanization.
The size of upper cushion pad and lower cushion pad is set as requested.Generally, the area of the shared lower outside dome platform of the abundant and lower cushion pad of upper cushion pad is larger, like this, is conducive to die ejector pin and produces due effect.
