The utility model relates to a casting mould, especially a die-casting mould for the cylinder blocks of the petrol engines, which comprises a cover die, a moving mould part, and a left slide block, a right slide block, an upper slide block and a lower slide block which are arranged on the four sides of the moving mould. A sliding slide block is arranged on the circumference of the moving mould which proceeds with horizontal motion relative to the cover die, and a runner system of a casting is arranged on the core of the cover die. The utility model is characterized in that the utility model has reasonable design, can cast the cylinder blocks with high quality, etc.

Description

The cylinder block compression mod

Technical field

The utility model relates to a kind of casting mould, particularly a kind of die casting of gasoline engine cylinder body.

Technical background

Cylinder block is the vital part in the gasoline engine, it also is the part that has in gasoline engine die casting and even the die casting than high technology content and better quality requirement, each serial cylinder block size and local shape are different, but the basic structure form reaches unanimity, and has determined the basically identical of its mould structure form.

Summary of the invention

The utility model has solved problems of the prior art, provides a kind of reasonable in design, can cast the cylinder block compression mod of high-quality cylinder block.

Above-mentioned technical purpose of the present utility model mainly solves by the following technical programs: comprise cover half, dynamic model part and be arranged at the left slider of dynamic model four sides, right slide block, top shoe and sliding block, around the dynamic model that carries out horizontal movement with respect to cover half, be provided with sliding slider, on the cover half core, offer the runner system of foundry goods.By being fixed on dynamic model on the die casting machine, cover half closing up or separately partly; produce matched moulds and die sinking action; around the dynamic model that carries out horizontal movement with respect to cover half, be provided with upper and lower, left and right four sideslip movable sliders; these slide blocks are along with the horizontal movement (matched moulds, die sinking) of dynamic model; and finish lock pin or the action of loosing core; form the cavity of foundry goods during lock pin, be shaped casting after loosing core and be ejected and leave casting mold precondition is provided.

As preferably, traditional running gate system mode and charging form have been changed, described four side slides are except that forming the foundry goods cavity, suitably done to increase, it is increased part and cooperates through the inclined-plane with the core that is arranged on the cover half middle part, described runner system comprises sprue, main cross gate that links to each other with sprue and the some branches cross gate that links to each other with main cross gate, and branch's cross gate communicates with wedge shape charging ingate again.During injection, sprue flows to three stocks on the cover half core by main cross gate and props up ingate and enter die cavity.Realized wall thickness charging from foundry goods, the continuous filling and the pressure that help die cavity pass speed, avoided washing away to core, cast gate is offered at the heavy wall place, the principle that meets the foundry goods consecutive solidification, help forming fine and close imperforate interior material tissue, knife gate also is easy to remove from foundry goods, also meet and shorten the principle that molten metal is filled flow process as far as possible, reduced the casting of owing of thin-walled fin, can be full of simultaneously each fin in advance and fill to the foundry goods bottom more later on, overflow overflow launder that the gas in the die cavity can cavity edge be provided with in the cylinder mouth of slider bottom and the air discharge duct.

As preferably, also respectively be provided with shaping core in a place on described left slider and the right slide block, form the two angle hydraulic pressure core-pulling mechanisms of non-equal angular eclipsed form.

As preferably, the length of described wedge shape charging ingate is 50mm.

Therefore, it is little to the utlity model has floor space, the efficient height, and working environment is better, and good product consistency, operation are comparatively simple, and production cost is lower, is beneficial to characteristics such as large-scale production.Inner chamber of cylinder block is by the dynamic mould core moulding, and the spark plug chamber is by the cover half core moulding, and foundry goods four side sides are recessed by four sides slide block moulding.Wherein, the shaped portion on cover half, dynamic model and the slide block all adopts heat-resisting alloy tool steel, the whole nodular iron casting of framed employing, and the intensity height, good rigidly, flexibly movable, the location is reliable, and repeat performance is better.

Specific embodiment

Below by embodiment, and in conjunction with the accompanying drawings, the technical solution of the utility model is described in further detail.

Embodiment 1: as shown in Figure 1, left slider 1 is provided with shaping core 2, and it is provided with increases part 3; As shown in Figure 2, top shoe 4 is provided with and increases part 5; As shown in Figure 3, right slide block 6 is provided with increases part 8, is provided with shaping core 7 in the right slide block; As shown in Figure 4, sliding block 9 is provided with and increases part 10.

As shown in Figure 6, cover half is provided with core 16, and the part of increasing of left slider, top shoe, right slide block and sliding block cooperates by the inclined-plane with it, is provided with wedge shape charging ingate on the cover half core, and the height of wedge shape charging ingate is 50mm.As shown in Figure 5, the core of cover half is provided with the running channel runner system, comprises sprue 13, and the main cross gate 14 that links to each other with sprue communicates with wedge shape charging ingate with three branch's cross gates 11,12,15 that link to each other with main cross gate, branch's cross gate 11,12,15.

Cover half, dynamic model, left slider, right slide block, top shoe and sliding block have been formed the die cavity of foundry goods, core cavity is by the active and inactive mold core moulding, the spark plug chamber is by the cover half core moulding, foundry goods four side sides are recessed by four sides slide block moulding, four sides slide block and cover half core are by the inclined-plane driving fit, during injection, sprue flows to three stocks on the cover half core by main cross gate and props up ingate and enter die cavity.

Change the inner chamber of cylinder block Edge feed and be vertical charging from bottom blade end face similarity gate form, utilize four slide blocks of increasing to form the foundry goods cavity and form the running channel die joint simultaneously, on the cover half core, offer sprue, main cross gate and branch's cross gate, the wedge shape charging ingate at two places and one place, left side below offering on the taper faying face of cover half core and four slide blocks, its form is with putting cast gate, but its ingate form is linear cast gate, enters the foundry goods shaped design at place according to cast gate.Like this, wall thickness charging from foundry goods, the continuous filling and the pressure that help die cavity pass speed, avoided washing away to core, cast gate is offered at the heavy wall place, the principle that meets the foundry goods consecutive solidification, help forming fine and close imperforate interior material tissue, knife gate also is easy to remove from foundry goods, also meet and shorten the principle that molten metal is filled flow process as far as possible, reduced the casting of owing of thin-walled fin, can be full of simultaneously each fin in advance and fill to the foundry goods bottom more later on, overflowed overflow launder that the gas in the die cavity can cavity edge be provided with in the cylinder mouth of slider bottom and the air discharge duct.
