Abstract

The utility model relates to a die of a production shock damper support, which comprises a body which corresponds to a support, wherein the area of a pouring gate of the body is between 540 mm2 and 580 mm2, the pouring gate is connected with aluminum water, the pouring gate is connected with the body and is connected with the neck portion of a shock damper through a gap bridge pipe, the front section of the gap bridge pipe is added with an overflow block, and two exhaust grooves which are respectively arranged on the left and the right sides are arranged on two sides of the body. The die has the beneficial effects that the die is not provided with local fractures after assembling through die-casting production detection, a sink-hole is not arranged on the neck portion, and no air bubbles are produced after T6 thermal treatment.

Description

Produce the mould of shock absorber support
Technical field
The utility model relates to a kind of mould, relates in particular to the mould of a kind of production automobile (Nissan) shock absorber support.
Background technology
As seen from Figure 1: shock absorber support is the vital part on the Nissan automobile, abroad is to adopt forged steel shaping after-baking to carry out fine finishining more all the time.European afterwards designer considers that vehicle weight will alleviate proposition and will make with aluminum alloy materials, product requirement requirement of strength δ b 〉=250Mpa, product will be through T6 heat treatment, and product occurring through regular meeting in Japan's trial production has in local fracture situation and the production process product bubble more after assembling; Damper neck 101 places shrinkage cavity among Fig. 1 is bigger, and reason wherein is mould is difficult to be equipped with extruding die casting at the design aspect of running channel, overflow piece, air discharge duct a ordinary production.
As seen from Figure 2: running channel 203 cross-sectional areas of available technology adopting Japan mould are less, and air discharge duct 204 intercommunication exhausts are not smooth, and neck 101 places among Fig. 1 are too far away apart from cast gate, herein the thickest extruding undercompensation of product
The subject matter of structure mold existence is as follows like this:
1. the running channel cross-sectional area is too little, and after aluminium water entered running channel, aluminium water cooling speed caused extruder pressure to upload to cause product monolithic extruded unreal soon;
2. air discharge duct intercommunication can cause among Fig. 2 that two side places, 201 gases can be involved in neck upper end 202 under the damper neck, cause product through T6 heat treatment after the product bubble a lot;
3. the damper neck 101 places shrinkage cavity among Fig. 1 is bigger, and mechanical performance of products can not well guarantee.
Summary of the invention
The utility model technical issues that need to address have provided a kind of mould of producing shock absorber support, are intended to solve the above problems.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
The utility model comprises: with the corresponding body of support; The area of the running channel of described body is at 540mm 2-580mm 2Between; Running channel connects aluminium water; Described running channel connects body and is connected damper neck place by cross under; The cross under leading portion increases the overflow piece; About be respectively two sides that 2 air discharge duct is placed in body.
Compared with prior art, the beneficial effects of the utility model are: by the detection that die casting is produced, do not have the local fracture situation to produce after the assembling, the neck place does not have shrinkage cavity, through not having bubble after the T6 heat treatment yet.
Description of drawings
The structural representation of Fig. 1 automobile damper bracket;
Fig. 2 is the mould structure schematic diagram of production drawing 1 in the prior art;
Fig. 3 is the utility model structural representation.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail:
As seen from Figure 3: the utility model comprises: with the corresponding body 10 of support; The area of the running channel 302 of described body 10 is at 540mm 2-580mm 2Between; Running channel 302 connects aluminium water 303; Described running channel 302 connects body 10 and is connected damper neck place by cross under 304; Cross under 304 leading portions increase overflow piece (not shown); About be respectively two sides that 2 air discharge duct 301 is placed in body 10.
The cross-sectional area that the utility model increases running channel has original 288mm 2Change 560mm into 2Air discharge duct is divided into two bursts of discharges of a, b, and the centre adds gap bridge, and the gap bridge leading portion increases the overflow piece.
After running channel 302 was widened, the aluminium water cooling was the slowest herein, can be expressed to the aluminium water at place, running channel bottom 303 on the body, had guaranteed the bulk strength of product.
The utility model is changed for the mode of air discharge duct compared to existing technology, original design can cause the gas at two side places 202 under the damper neck can be involved in neck upper end 201, thereby cause product through T6 heat treatment, product bubble fraction defective reaches more than 40%, after two strands of gases separated, gas all came the mould outside and greatly reduces the product rejection that causes because of the product bubble.
The utility model is passed a bridge by increasing, and aluminium water can directly directly squeeze the part aluminium water at place, running channel bottom 303 at damper neck place 101 when extruding, and the place's shrinkage cavity of damper neck reduces greatly, has increased the weak local intensity of product.
The utility model improves the squeezing effect that die casting is produced by increasing the cross section integration of running channel, guarantees the extrusion performance in the die casting production process, thereby product strength is improved, and product is qualified to be improved greatly.
