Description
Technical field
The utility model relates to technical field of mold, is specifically related to a kind of low-loss gravity casting mould of automobile engine intake tube.
Background technology
The air inlet pipe of engine of heavy-duty car generally adopts the gravity casting mould of metal material shaping, as shown in Figure 6, body bottom due to air inlet pipe has evagination position C, therefore need during casting to make the loose piece corresponding with evagination position C in the die cavity of counterdie, otherwise cannot the demoulding after air inlet pipe casting.General employing sand lump uses as the loose piece of gravity casting mould, and during the workpiece demoulding, push rod is by workpiece together with sand lump jack-up, and abate sand lump completes stripping process afterwards.A conventional gravity casting mould air inlet pipe of casting needs use six sand lumps, all need, by sand lump abate one by one, to waste time and energy, affect production efficiency at every turn, because sand lump is disposable product, each casting all needs to change, and therefore loss is comparatively large, causes production cost higher, and due to the surface of sand lump comparatively coarse, cause the corresponding position of air inlet pipe easily to produce pore, affect the quality of air inlet pipe, wait to improve.
Utility model content
The purpose of this utility model overcomes the deficiency in above-mentioned background technology, a kind of gravity casting mould of automobile engine intake tube is provided, this gravity casting mould is without the need to using sand lump, thus reduction production cost, enhance productivity, Improving The Quality of Products, and there is simple, the easy to operate feature of structure.
For realizing above object, the utility model have employed following technical scheme:
A kind of low-loss gravity casting mould of automobile engine intake tube, comprise the upper die and lower die offering die cavity respectively, upper die and lower die are configured with the one group of push rod driven by actuating unit respectively, it is characterized in that: on front side of the die cavity of described counterdie, offer several recesses respectively with rear side, by skewed slot and guiding edge strip, one metal block is installed in each recess, described skewed slot is from the bottom outward-dipping end face extending to counterdie always of counterdie, and described in the top rod driving of counterdie, metal block moves along skewed slot.
The bottom of described recess offers the guide through hole that at least one penetrates into counterdie bottom surface downwards, and the push rod of counterdie is from the bottom up through the bottom surface being resisted against metal block after guide through hole.
Described guiding edge strip and skewed slot match, and the two ends, left and right of each metal block are equipped with the edge strip that to lead described in, guiding edge strip and metal block one-body molded.
The upper end of one group of push rod of described patrix is connected on upper ejector pin plate, and the lower end of one group of push rod of counterdie is connected on lower push rod plate, and upper ejector pin plate and lower push rod version are driven by described actuating unit respectively.
Described actuating unit is oil cylinder.
The beneficial effects of the utility model are: the utility model utilizes metal block to substitute sand lump, and the surface due to metal block can process very smooth, therefore effectively can reduce or avoid occurring sand hole, Improving The Quality of Products; Secondly, because skewed slot is to the guide effect of metal block, during the demoulding, push rod is by the process of metal block jack-up, and skewed slot can move by guide wire loose piece laterally, metal block and air inlet pipe are departed from, avoid interference knockout course, without the need to manually loading and unloading metal block in this process, structure is simple, easy to use, operating efficiency improves greatly, and the difference of metal block and sand lump is that metal block can reuse, can be greatly cost-saving.

Detailed description of the invention
Below in conjunction with Figure of description, the utility model is described in further detail, but the utility model is not limited to following examples.
As Figure 1-Figure 5, the low-loss gravity casting mould of a kind of automobile engine intake tube described in the utility model, comprise the patrix 2 and counterdie 3 that offer die cavity respectively, upper die and lower die are metal pattern, upper die and lower die are configured with the one group of push rod 5 driven by actuating unit respectively, and this actuating unit is generally oil cylinder.
Several recesses are offered respectively with rear side on front side of the die cavity of described counterdie, described recess is arranged on the position of existing installation sand lump, by skewed slot 7 and guiding edge strip 8, a metal block 6 is installed in each recess, metal block is shaped with the forming surface (similar with sand lump) of air inlet pipe, the material of described metal block is identical with upper die and lower die, such as iron or steel.Described skewed slot is from the bottom outward-dipping end face (gradient of skewed slot is determined as required) extending to counterdie always of counterdie, and described in the top rod driving of counterdie, metal block moves along skewed slot.The bottom of described recess offers the guide through hole that at least one penetrates into counterdie bottom surface downwards, and the push rod of counterdie is from the bottom up through the bottom surface being resisted against metal block after guide through hole.
Described guiding edge strip and skewed slot match, and the two ends, left and right of each metal block are equipped with the edge strip that to lead described in, guiding edge strip and metal block one-body molded.The upper end of one group of push rod of described patrix is connected on upper ejector pin plate 1, and the lower end of one group of push rod of counterdie is connected on lower push rod plate 4, and upper ejector pin plate and lower push rod version are driven by described actuating unit respectively.
