Description

A kind of pin row casting mould

Technical field

The invention belongs to pin row casting fields, and in particular to a kind of pin row casting mould.

Background technology

Pin row is the important component of scrapper conveyor, since pin row is in coalcutter fuselage bottom, born under heavy duty alternate stress and Load, so often being replaced in overhaul to pin row.It is at this stage de- frame mold life to the mode of production for casting pin row Production, single moulding produce one, low production efficiency；The no sandbox in outside is fixed, and in order to which moulding consolidates, each moulding must be used strong Larger fresh sand is spent, it is of high cost.

Utility model content

The purpose of this utility model is to provide an a kind of moulding more than one piece, production efficiency height, a kind of pin row casting for saving sand Modeling has.

The purpose of this utility model is realized in the following manner：A kind of pin row casting mould, including upper die and lower die, on Mould includes sprue gate cylinder, and lower die includes running channel, and upper mold includes at least two row's pin row upper molds, and lower die is included at least under two row's pin rows Mould；Sandbox is set outside upper die and lower die, and at least pin row upper mold is misaligned described in two rows, and at least pin row lower die is not right described in two rows Together, running channel has inclined angle.

The correspondence position on three sides of upper die and lower die sets 3 upper mold positioning pins and 3 lower die positioning pins respectively.

The beneficial effects of the utility model are：Production efficiency is improved to be become once making from original single moulding production one Type produces four；The old husky moulding in part can be used, the usage amount of new sand is greatly saved, the amount ratio of quartz sand saves hundred originally / 50；Surface quality is bright and clean, compared to de- frame cast(ing) surface, it is ensured that smaller mould shift amount.The utility model production efficiency It greatly improves, has saved cost, it is ensured that the higher market competitiveness of Products.

Wherein, 10 be single pin row upper mold, and 11 be first row pin row upper mold, and 12 be second row pin row upper mold, and 13 be the 3rd Pin row upper mold is arranged, 14 be the 4th row's pin row upper mold, and 20 be single pin row lower die, and 21 be first row pin row lower die, and 22 be second row Pin row lower die, 23 be the 3rd row's pin row lower die, and 24 be the 4th row's pin row lower die, and 30 be sprue gate cylinder A, and 31 be sprue gate cylinder B, 40 be running channel A, and 41 be running channel B, and 51 be upper mold positioning pin A, and 52 be upper mold positioning pin B, and 53 be upper mold positioning pin C, under 61 are Mould positioning pin A, 62 be lower die positioning pin B, and 63 be lower die positioning pin C.

Specific embodiment

As shown in Figs. 1-2, frame upper mould, lower die top view are taken off, is set on de- frame upper mould in single pin row Mould 10 and sprue gate cylinder A30 take off and set single pin row lower die 20 and running channel A40 on frame lower mould.Molding sand is filled into Enter the de- upper and lower modeling of frame mold.The each moulding one of de- frame mold, and it is flaskless, in order to which moulding consolidates, make every time Type must be all with the larger fresh sand of intensity.

As shown in Figure 3-4, the utility model upper mold includes sprue gate cylinder B31 and the first row pin row upper mold being arranged in parallel 11st, second row pin row upper mold 12, the 3rd row's pin row upper mold 13, the 4th row's pin row upper mold 14, three angles of the utility model upper mold Upper setting upper mold positioning pin A51, upper mold positioning pin B52, upper mold positioning pin C53.The utility model lower die includes running channel B41 peace First row pin row lower die 21, second row pin row lower die 22, the 3rd row's pin row lower die 23, the 4th row's pin row lower die 24 of row setting, Lower die positioning pin A61, lower die positioning pin B62, lower die positioning pin C63 are set on three angles of the utility model lower die.This practicality It is fixed respectively with sandbox outside new upper die and lower die.Running channel B41 includes connection first row pin row lower die 21 and second row pin row lower die 22 inclination running channel, the 3rd row's pin row lower die 23 of connection and the 4th row's pin row lower die 24 inclination running channel and be connected two inclinations and pour The trunk running channel in road.

First row pin row upper mold 11 and second row pin row upper mold 12 are misaligned, the 3rd row's pin row upper mold 13 and the 4th row's pin row Upper mold 14 is misaligned, and first row pin row lower die 21 and second row pin row lower die 22 are misaligned, the 3rd row's pin row lower die 23 and the 4th Row's pin row lower die 24 is misaligned, and such running channel B41 includes inclined part and tilts running channel, and impact force is small when cast, prevents Falling stop sand.Upper mold positioning pin A51, upper mold positioning pin B52, upper mold positioning pin C53 formed cavity respectively with lower die positioning pin The cavity that A61, lower die positioning pin B62, lower die positioning pin C63 are formed corresponds, and position is correct during for ensureing mould assembling.

The quantity that pin row upper mold and pin row lower die are corresponded in the upper die and lower die of the utility model is not to be only 4, Quantity is at least 2.

When it is implemented, the utility model upper mold is put into inside sandbox, one layer of fresh sand is first filled, is subsequently filled old sand, directly To concordant with sandbox, blow carbon dioxide solidification, from sandbox inside remove the utility model upper mold, form lower space design.This reality It is also handled in the same manner with new lower die, space design in formation.Using old sand, cost has been saved, has improved company Competitiveness.3 positioning pin cores are produced by core box.3 positioning pin cores are put into 3 dowel holes of lower space design Face, mould assembling, positional fault when preventing sandbox mould assembling by positioning pin core.It pours into a mould from sprue gate after mould assembling, is flowed to by running channel Inside the cavity that four row's pin row upper molds and four row's pin row lower dies are formed, pin row is cast as, by processing, once produces four rows pin Row, production efficiency increase substantially.
