Description

The demolding structure of emery wheel abrasive material mould

Technical field

The technical field of grinding is the utility model is related to, particularly relates to a kind of demoulding of emery wheel abrasive material mould Structure.

Background technology

Traditional emery wheel is to form a circle annular abrasive material by being molded in base circumferential outer surface, and traditional moulds are A circular groove structure is formed in mould outer ring, matrix is placed in this circular groove structure, and abrasive material pours into matrix and ring Between connected in star structure, matrix is pushed down by cover plate, annular upper holder block pushes down abrasive material and forms abrasive material, and press from top to bottom will Upper holder block is depressed, and heat-insulation pressure keeping is molded under certain condition, is completed through solidify afterwards product, this kind of mould is because abrasive particle is than bonding agent ratio Great, any concussion all easily causes abrasive particle as bottom deposition, and concussion is serious when the emery wheel of produced in conventional processes produces, Vertical Square It is big to distance, cause the emery wheel inside abrasive particle distribution side side on the high side of production on the low side, ground effect is influenceed, to solve above-mentioned ask Abrasive material, can be designed to that multiple abrasive sheets are pasted onto matrix surface, emery wheel abrasive material mould only needs horizontal compacting by topic Shaped abrasive piece, and due to needing multiple abrasive sheets on an emery wheel, it is necessary to realize that emery wheel abrasive material mould is fast Fast shaped article, the multiple products of one-shot forming, the multiple products of one-shot forming, it is necessary to set baffle plate to form in a mould Multiple molding cavities, and because resin flowing under pressure be full of die cavity when producing, demoulding difficulty is caused, can not smoothly be taken off Mould.

Utility model content

In order to overcome drawbacks described above, the utility model provides a kind of demolding structure of emery wheel abrasive material mould, the sand The demolding structure of wheel abrasive material mould can realize that the single abrasive material flake products of emery wheel abrasive material are smoothly stripped, and improve emery wheel mill The uniformity of the bed of material.

The utility model in order to solve its technical problem used by technical scheme：A kind of emery wheel abrasive material mould Demolding structure, including cushion block and first the demoulding block, cushion block can stop be positioned on the workbench of press, the cushion block be able to The framed downside of abrasive material mould is supported in, and engraved structure is formed between cushion block, the backing plate of abrasive material mould is proper Engraved structure face between cushion block, the first demoulding block can be positioned on the briquetting of abrasive material mould and tight against briquetting It is set to be slided along abrasive material mould depth direction, first demoulding block is just immediately below the pressure head of press.

As further improvement of the utility model, prolong on the inside of the abrasive material mould formed with least one pair of longitudinal direction The socket stretched, what can be slided along die depth direction in the socket is provided with baffle plate, and baffle plate is by abrasive material mould medial septal It is disconnected to form several forming cavities for supplying abrasive media, the second demoulding block is additionally provided with, the second demoulding block be able to be inserted in abrasive material Between adjacent briquetting and tight against each baffle plate uper side surface in mould, and the second demoulding block upper end is higher by abrasive material shaping mould Each briquetting upper end setting height of tool.

As further improvement of the utility model, the baffle plate includes the first trapezoidal plate, the second trapezoidal plate and clapboard, Between what the clapboard can slide along mold frame structure depth direction is inserted in first and second trapezoidal plate, first and second trapezoidal plate phase To side wall be inclined-plane, the opposite side wall of first and second trapezoidal plate is vertical plane, and first and second trapezoidal plate opposing sidewalls are just and wedge Shape plate both sides inclined-plane, which coordinates, to be adjacent to, and is additionally provided with a wedge drive device, the wedge drive device can drive wedge court Slide one end big to its width.

As further improvement of the utility model, wedge drive device is the 3rd demoulding block, and the 3rd demoulding block be able to Enough and clapboard upper end face, and the 3rd demoulding block be able to be inserted between first and second trapezoidal plate, the 3rd demoulding block upper end is high Go out each briquetting upper end setting height.

The beneficial effects of the utility model are：The utility model is padded by framed lower set in abrasive material mould Block, the first demoulding block is set on the briquetting of abrasive material mould, the first demoulding block is compressed by press, and then pass through briquetting Backing plate and product are pressed out, realize feeding, the utility model is also by being in two by the baffle plate setting in abrasive material mould The structure that individual trapezoidal plate and a wedge coordinate, exiting for wedge is realized by the 3rd demoulding block, and then increase abrasive material The forming cavity large space of mould, first pass through the second demoulding block and first and second trapezoidal plate is extruded into abrasive material mould, then lead to Cross the first demoulding block and realize product stripping, because the wedge band of centre is gradient, can just make its abjection with less power, by In shaping cavity space increase, first and second trapezoidal plate also is easy to, and then realizes the quick abjection of baffle plate, once baffle plate takes off Going out, the demoulding of backing plate and product just becomes very easy, therefore, abrasive material mould fast demoulding of the present utility model, The smooth demoulding of multiple products while shaping is realized, stripping rate is fast, does not damage product, ensure that product quality.
