Description

The rail mounted die-sinking device

The utility model provides a kind of rail mounted die-sinking device, and You Zhiqi can prevent that when matched moulds air from residuing between the mould, and the operation of steady and smooth then is provided in the die sinking process, and then makes the fraction defective of product reduce to minimum.

Traditional vacuum die casting machine such as Fig. 6 are to shown in Figure 9, it is provided with a patrix 1 and a counterdie 2 on board, this patrix 1 is to be incorporated into one to lift below the template 11, be provided with a discrepancy template 6 in counterdie 2 belows, be provided with down electric hot plate 4 in template 6 belows of coming in and going out, but its lifting of driving device controls that this time electric hot plate 4, the template 6 of coming in and going out and counterdie 2 nationalitys are established by other; Be provided with a board seat of honour 8 corresponding to the board in upper and lower mould 1,2 home positions top, this board seat of honour 8 is below in conjunction with there being electric hot plate 3 on, laterally is provided with several pin rods 12 in two sides of patrix 1; Board in the depanning direction is provided with lowering or hoisting gear A in addition, this lowering or hoisting gear A is provided with one group of pneumatic cylinder A1 below board, the cylinder axle of this pneumatic cylinder A1 extends to the board top and is provided with a top trigger A2, and the board between lowering or hoisting gear A and die holder is provided with the pulley A4 that is positioned at suitable height.This upper and lower mould 1,2 behind the matched moulds is being the die holder position above the electric hot plate 4 under nationality is sent into it by the template 6 of coming in and going out, treat to make drive unit will descend electric hot plate 4 upwards to rise behind the mould together with come in and go out template 6 and counterdie 2, and then make vacuum (-tight) housing 5 cover upper and lower mould 1,2, and will vacuumize and give simultaneously supercharging (as shown in Figure 6) in the vacuum (-tight) housing 5, through precompressed, pressurization, exhaust, add sulphur final vacuum cover 5 and rise gradually and open (as shown in Figure 7); This discrepancy template 6 is delivered to upper and lower mould 1,2 the depanning seat and puts and arrive directly over the lowering or hoisting gear A together with lifting template 11 after waiting to finish.(as shown in Figure 8), make and be located at the recess A3 of the pin rod 12 of patrix 1 two surveys corresponding to the top trigger A2 of lowering or hoisting gear A, automatically the pneumatic cylinder A1 that starts lowering or hoisting gear A subsequently rises, utilize its top trigger A2 will lift template 11 jack-up, rise to end limit that certain altitude lifts template 11 season and touch pulley A4 and make that to lift template 11 be center and upwards lift and open with its pivoting point with lifting template 11 until patrix 1, reach the purpose of die sinking according to this; And control pre-trigger A2 and lift template 11 when descending synchronously together with patrix 1 as pneumatic cylinder AI, then nationality makes its downward bias by the patrix 1 and the weight of lifting template 11 itself then is closed in counterdie 2.

The die-sinking device of above-mentioned traditional vacuum die casting machine no doubt provides the function that can automatically patrix be opened, yet, because its lowering or hoisting gear of must nationality being established by other is with patrix and lift and make patrix touch pulley again after template promotes can opening, so not only structure is complicated, manufacturing cost is higher, and lift that template rises and when touching pulley, because the effect of impact, to make that whole lowering or hoisting gear is related to be given a shock, and then influence the precision of the foundry goods in the counterdie, more may make foundry goods break away from counterdie when serious and damage, even cause stopping of machine; So the utility model i.e. existing shortcoming of the above-mentioned traditional die-sinking device of pin is improved and is developed.

Main purpose of the present utility model is providing a kind of rail mounted die-sinking device, be be provided with by arc of horizon in the appropriate location of the depanning direction of board curved to vertical track, be provided with roller in template two sides of lifting in addition in conjunction with patrix, nationality with upper and lower mould together with lifting template when the direction of track is carried, made roller transmit the upright position by level along track, and then make cope match-plate pattern lift and open in vertical state in company with lifting template, shake when avoiding die sinking, and can reduce manufacturing cost according to this.

Another purpose of the present utility model after providing upper and lower mould and covering, can keep certain clearance between the two when not precompressed as yet, pressurization, to avoid making air wherein residual because of covering in the upper and lower mould before vacuumizing, cause the fraction defective raising of product.

Rail mounted die-sinking device provided by the utility model, include a patrix and a counterdie, on being somebody's turn to do, counterdie is that nationality is articulated it on one side each other by a hinge device, and patrix is to be fixedly arranged on one to lift below the template, be provided with a discrepancy template in the counterdie below, the template below is provided with down electric hot plate in coming in and going out, be provided with electric hot plate in the patrix top, but its lifting of driving device controls that this time electric hot plate is established by other together with come in and go out template and counterdie nationality, on being somebody's turn to do, counterdie is that nationality is transferred it by the template of coming in and going out, it is characterized in that: these two surveys of lifting the close end limit of template are provided with a holder, be pivoted with a movable block in this holder, this movable block is provided with a through hole, is pivoted with roller respectively in lifting the template dual side-edge in addition; This is provided with an axostylus axostyle in upright respectively ground, two appropriate locations of surveying above discrepancy template, and makes axostylus axostyle pass the through hole of movable block; Two side appropriate locations are respectively equipped with by the curved track to vertical topography of arc of horizon above the board of depanning direction, nationality is so that upper and lower mould is when shifting out simultaneously, made and be located at the roller that lifts template and roll, and then make patrix and lift template and lift the breakdown mould with the pivoting point between sliding seat and holder simultaneously along guide rail.

The utility model has the advantages that when having avoided die sinking and shake, and can reduce manufacturing cost, improve the quality of products.

Other purposes of the present utility model and function can be understood after cooperating following accompanying drawing to be further described in more detail, and only the following stated in order to explain preferred embodiment of the present utility model, is not that the utility model is done to appoint with pro forma restriction only.
