Abstract

The utility model discloses a high-performance modular precise extrusion mold which comprises a bottom plate module (1), a stock mold module (2) and a cover plate module (3), wherein two or three sections of the stock mold module (2) are arranged; the stock mold module (2) is connected with the bottom plate module (1) through a stock mold fixing screw (4); the cover plate module (3) is connected with the stock mold module (2) through a cover plate fixing screw (5); the high-performance modular precision extrusion mold also comprises positioning pins (7) and positioning pin fixing screws (6); a bottom plate module groove (11) is formed above the bottom plate module (1); a position, which corresponds to the bottom plate module groove (11), at the lower surface of the stock mold module (2) is provided with a stock mold module groove (21) of which the width is the same as that of the bottom plate module groove (11); and two positioning pins (7) are arranged on each section in the stock mold module (2). The high-performance modular precision extrusion mold is simple in structure, easy to mount, high in positioning precision and low in cost.

Description

A kind of high-performance Modularized Precision extrusion die

Technical field:

The utility model relates to extrusion die, specifically a kind of high-performance Modularized Precision extrusion die.

Background technology:

The stock mould of existing extrusion die often has two joint or three joints, when the stock mould of processing and installation extrusion die, after first every joint being processed, be installed in one by one on the base plate again, then, with workman's range estimation each joint is carried out centering and install, and make each center of saving on same straight line, after adjusting, stock mould and base plate is bonding or connect together with tool holder by gluing, beat again the pin location, and with screw pin is strained, adopt this mode, positioning accuracy is low, and very time-consuming, the Product Precision that especially adopts this Mould Machining to go out is low, and is second-rate.

The utility model content:

The purpose of this utility model just provide a kind of simple in structure, be easy to install, positioning accuracy is high, cost is low high-performance Modularized Precision extrusion die.

For achieving the above object, the utility model comprises floor module, stock mould module and cover plate module, the joint number of stock mould module can be two joints or three joints, the stock mould module is connected with floor module by the stock mould hold-down screw, the cover plate module is connected with the stock mould module by the cover plate hold-down screw, also comprise alignment pin and alignment pin hold-down screw, be provided with the floor module groove above the described floor module, following and the floor module groove opposite position of described stock mould module is provided with the stock mould module slot with floor module groove same widths, the part of described alignment pin is loaded in the floor module groove, and with the alignment pin hold-down screw alignment pin is strained, another part of described alignment pin then stretches in the stock mould module slot, and the quantity of described alignment pin arranges by two at every joint in the stock mould module; Between described alignment pin and the floor module groove cooperate and alignment pin and stock mould module slot between cooperate and all adopt matched in clearance.

The utility model is owing to be provided with the floor module groove on floor module, below the stock mould module, be provided with stock mould module slot with floor module groove same widths with floor module groove opposite position, the part of alignment pin is loaded in the floor module groove, and with the alignment pin hold-down screw alignment pin is strained, another part of alignment pin then stretches in the stock mould module slot, again since alignment pin respectively with the floor module groove, matched in clearance is all adopted in cooperation between the stock mould module slot, so when floor module is installed respectively saving of typing module, become very easy, and positioning accuracy is high, the Product Precision that goes out with this Mould Machining is high, and quality is good.The utility model is simple in structure, is easy to install, and positioning accuracy is high, and cost is low.

Description of drawings:

Fig. 1 is overall structure schematic diagram of the present utility model.

The specific embodiment:

Referring to Fig. 1, the utility model comprises floor module 1, stock mould module 2 and cover plate module 3, the joint number of stock mould module 2 can be two joints or three joints, stock mould module 2 is connected with floor module 1 by stock mould hold-down screw 4, cover plate module 3 is connected with stock mould module 2 by cover plate hold-down screw 5, also comprise alignment pin 7 and alignment pin hold-down screw 6, be provided with floor module groove 11 above the described floor module 1, following and floor module groove 11 opposite positions of described stock mould module 2 are provided with the stock mould module slot 21 with floor module groove 11 same widths, the part of described alignment pin 7 is loaded in the floor module groove 11, and with alignment pin hold-down screw 6 with alignment pin 7 tension, another part of described alignment pin 7 then stretches in the stock mould module slot 21, and the quantity of described alignment pin 7 arranges by two at every joint in the stock mould module 2.Between described alignment pin 7 and the floor module groove 11 cooperate and alignment pin 7 and stock mould module slot 21 between cooperate and all adopt matched in clearance.

During actual installation, first alignment pin 7 is inserted in the floor module groove 11, then use alignment pin hold-down screw 6 with its tension, successively the stock mould module slot 21 of stock mould module 2 each joint is aimed at alignment pin 7 again, alignment pin 7 is inserted in the stock mould module slot 21, like this, just very rapid and very accurately stock mould module 2 is installed on the floor module 1.
