Strong magnets template detent mechanism
Technical field
The utility model belongs to the foundry machinery field, particularly a kind of strong magnets template detent mechanism.
Background technology
For some specialities casting processing, on foundry production line, must adopt special processing mode, for example in the casting process of parts such as automobile camshaft, the flange portion of camshaft needs chilling to handle, to guarantee that flange portion has higher abrasion resistance, usually adopt the mode of on template, placing chill to carry out moulding for reaching this purpose, make molten iron at chill periphery chilling in the molten iron cast step thereby be implemented in.But, then need all place chill on the upper and lower surface of template for the step of overall modelling that must adopt match plate.At the mode comparative maturity of template upper surface placement chill, can finish automatically by modes such as manipulators, at present then can only be for placing chill by manually operating at the template lower surface.Yet, place very inconvenience of chill operation by artificial toward the template lower surface that is in eminence, hand labor intensity is big, and especially for the high-speed molding machine, manually-operated can not be satisfied process requirements more.
Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art, provide a kind of by magnet being set at the template lower surface, utilize riser to drive accessory plate the chill delivery is also adsorbed the magnet type board positioning mechanism that is positioned the template lower surface, it has the advantage of automaticity height, accurate positioning.
The utility model solves its technical problem and takes following technical scheme to realize:
A kind of strong magnets template detent mechanism comprises the template of level run on the moulding machine carriage, it is characterized in that: the lower surface at template is shaped on a plurality of magnetic anchor points; On this template bottom immobilizing foundation, bracing frame is installed, on this bracing frame, prop up one with the corresponding accessory plate in template position, upper surface at this accessory plate is shaped on a plurality of chill locating slots, and the position of these a plurality of chill locating slots is corresponding one by one with the position of the made magnetic anchor point of template; On the immobilizing foundation of accessory plate bottom, fixed mount is installed, the lifting cylinder vertically is installed on this fixed mount, install horizontal riser in the push rod end of this lifting cylinder.
And described template lower surface is shaped on a plurality of magnetic anchor points by the form of a plurality of magnet pieces of setting-in.
And, be fixed with alignment pin in the equal symmetry in the outside of each magnetic anchor point of described template lower surface, be shaped on chamfering at the relative inner face top of this alignment pin.
And described riser lower surface is fixed with guide post in the bilateral symmetry that promotes cylinder, and this guide post guiding is movably installed in the made guide pin bushing of fixed mount.
Advantage of the present utility model and good effect are:
1. this strong magnets template detent mechanism makes a plurality of magnetic anchor points at the template lower surface by the form of setting-in magnet piece, the accessory plate of one upper surface location chill is set in the template bottom, accessory plate rises to the template lower surface by the riser driving of its underpart, thus the chill of institute's setting-in on the accessory plate is adsorbed in the lower surface of template, realize the automation type magnetic location of chill, only need that manually chill is positioned over the accessory plate upper surface and get final product, thereby significantly reduce hand labor intensity.
2. this strong magnets template detent mechanism is fixed with alignment pin in the equal symmetry in the outside of each magnetic anchor point of template lower surface, is shaped on chamfering at the relative inner face top of this alignment pin, is convenient to the accurate location of chill.
3. this strong magnets template detent mechanism is fixed with guide post at the riser lower surface in the bilateral symmetry that promotes cylinder, to guarantee the lifting stationarity of riser.
4. the utility model scientific structure design is reasonable, can drive accessory plate by riser rises, the lower surface that chill magnetic on the accessory plate is positioned template will be positioned, realize the automatic magnetic location of chill thus, have the efficient height, locate advantages such as accurate, be specially adapted to the chill location of high-speed molding machine match plate.

The specific embodiment
The utility model is described in further detail below in conjunction with accompanying drawing, by specific embodiment.Following examples are descriptive, are not determinate, can not limit protection domain of the present utility model with this.
A kind of strong magnets template detent mechanism comprises the template 1 of level run on moulding machine carriage 2.Its innovative point is: be shaped on a plurality of magnetic anchor points in the lower surface of the template form by a plurality of magnet pieces 10 of setting-in.And the equal symmetry in the outside at each magnetic anchor point of template lower surface is fixed with alignment pin 11.All be shaped on the chamfering of being convenient to the accurate location of chill at the relative inner face top of this alignment pin.On this template bottom immobilizing foundation, bracing frame 5 is installed, on this bracing frame, prop up one with the corresponding accessory plate 4 in template position, upper surface at this accessory plate is shaped on a plurality of chill locating slots 12, and the position of these a plurality of chill locating slots is corresponding one by one with the position of the made magnetic anchor point of template.Fixed mount 9 is installed on the immobilizing foundation of accessory plate bottom, on this fixed mount, vertically is equipped with and promotes cylinder 7, install horizontal riser 6 in the push rod end of this lifting cylinder.Accurately locate the lifting height of accessory plate by the extreme position that cylinder is set.The riser lower surface is fixed with guide post 8 in the bilateral symmetry that promotes cylinder, and this guide post guiding is movably installed in the made guide pin bushing of fixed mount.
Operation principle of the present utility model is:
Manually chill 3 is positioned in the made locating slot of accessory plate upper surface one by one, promote cylinder and rise the steady rising of driving accessory plate near the template lower surface, the chill of being located on the accessory plate is adsorbed on the made magnetic anchor point of template lower surface, thereby finishes the lower surface chill location of match plate.This detent mechanism is finished required movement by cylinder, have simple in structure, be easy to adjustment, automaticity height, quick action, time saving and energy saving, advantage such as the location is accurate, the whole efficiency of mo(u)lding equipment, product quality all are improved.
