Description
Technical field
The present invention relates to a kind of fuel tank mould.
Background technology
At present, fuel tank mould is in order to avoid each auxiliary body and the cutting agency of mould upper end, by on die body corresponding for blow needle organization establishes mould cavity bottom, and the position of the corresponding blow needle of die cavity is the oil filler position of shaping rear fuel tank, therefore the relatively little one end of tank body of oil tank is also located in below, and the relatively large one end of casing is positioned at top; This just makes the fuel tank mould of prior art in the process of blow molding, easily walks downward, make the wall thickness of tank body of oil tank bottom relatively thick in the effect blanking of material self gravitation, and raw material also just needs more relatively, and then the cost of fuel tank is increased; And the inequality of wall thickness will make to shrink during fuel tank water-cooled shaping after shaping uneven, the profile of tank body of oil tank is easily out of shape, and tank body of oil tank also easily offsets on a large scale and causes the tank body of oil tank of clamping place to be out of shape, cause the yield rate of sizing lower, the cost of finished product is finally caused significantly to increase, and after the tank body of oil tank slight deformation of clamping place, easily causing the situation easily occurring in actual use leaking, quality stability is poor.
Summary of the invention
The present invention is directed to above problem provide a kind of materials comparatively to economize, be beneficial to product water cold formed, significantly can reduce product cost and the good fuel tank mould of quality stability.
The present invention overcomes the above problems technical scheme used: provide a kind of fuel tank mould with following structure, it comprises the die cavity on die body and die body, described die body is provided with blow needle mechanism, described blow needle mechanism is positioned at the upper end of die body, the Breadth Maximum of described die cavity upper end is less than the Breadth Maximum of die cavity lower end, the upper end of described die body is provided with arc track and line slideway, described blow needle mechanism slips is connected on arc track, and arc track is connected with die body by line slideway, the length direction of described line slideway and the plane orthogonal at die body place, described arc track is connected with line slideway by the support of " L " type, and arc track is positioned at the upper end of support, the below of described support is provided with square opening, the first cylinder is rotatably connected in described square opening, and axis during the first rotational cylinder is parallel with line slideway, described support is provided with arc-shaped through-hole, and arc-shaped through-hole extends along arc track, described blow needle mechanism and the piston rod of the first cylinder hinged, described die body is provided with the second cylinder, and the piston rod of the second cylinder is connected with support, and the piston rod of the second cylinder is parallel with line slideway.
After adopting above structure, compared with prior art, the present invention is due to after the arranging of arc track and line slideway, blow needle mechanism arc can be moved to avoid auxiliary body, then step back, can cutting agency be avoided, make blow needle mechanism can be arranged on the upper end of die body, then the Breadth Maximum of die cavity upper end is less than the Breadth Maximum of die cavity lower end, therefore in the process of blowing after charging, the center of gravity of material is relatively low, and under the extruding of lower end material self, material not easily walks downward, and then make the thickness of blow molding rear fuel tank casing relatively even, and can conservation be also use amount, and then reduction production cost, and in follow-up Cooling Process, because the thickness of casing is relatively even, casing each several part in water-cooled shaping process is made to shrink relatively even, offseting on a large scale also not easily appears in casing, and the stability of tank body of oil tank profile and uniformity better, and then significantly improve yield rate and reduce production cost, and clamping place is just not yielding yet, make the situation not easily occurring in actual use leaking, the reliability of quality is better, and the satisfaction of client also just better.Therefore the present invention have materials comparatively economize, be beneficial to product water cold formed, significantly can reduce product cost and the good feature of quality stability.
As improvement, described line slideway is connected with die body by fixed head, and the length of fixed head is more than or equal to the length of line slideway, the axes normal that described fixed head is corresponding with die cavity tank filler; Described line slideway is two, and two line slideways be arranged in parallel on sub-fixed head; The second described cylinder is fixed on fixed head, and on the position of the second cylinder between two line slideways; The one end in described fixed head plesiotype chamber is provided with the limited block to support upper limit; The stability then arranging rear line slideway is like this better, and then ensures the stability in use of mechanism, and after limited block arranges, do not need setting position induction installation, can reduce the preparation cost of equipment further, and dependability is good.
As further improvement, described support is provided with the travel switch for controlling blow needle mechanism shift position; Then travel switch makes the accuracy of blow needle mechanism movement higher after arranging, and then when relative displacement is less, can effectively avoid auxiliary body and cutting agency, thus improves operating efficiency of the present invention.
As improving further, described arc track is two again, and two arc tracks are arranged with one heart, and in two arc tracks, the diameter of one of them arc track is greater than the diameter of another arc track; On the position of described arc-shaped through-hole between two arc tracks; After then two arc track is arranged, make the stability of blow needle mechanism movement better, vibrations time mobile are also less, and then ensure the accuracy of blow needle, and the accuracy of blow needle mechanism movement is also just better, improves operating efficiency of the present invention further.
As improving further, the line between the center of circle that described arc track is corresponding and the center of circle corresponding to die cavity fuel tank oil pump snap ring is parallel with die body upper surface again; Arc track radian after arranging like this is relatively little, save raw material, the spacing of blow needle mechanism movement is also just relatively little, can effectively avoid auxiliary body and cutting agency again, further raising operating efficiency of the present invention, can reduce preparation cost of the present invention again simultaneously.
As improving further, described blow needle mechanism comprises slide block and blow needle seat again, and described blow needle seat is slidably connected on slide block; Described slide block is provided with the 3rd cylinder promoting blow needle seat and slide, and skid is connected on arc track; Described slide block is provided with the stroke sensor for blow needle seat; After then arranging like this, due to the slip of blow needle seat, the displacement of blow needle mechanism on arc track can be shortened further, and action can be carried out simultaneously, shorten the cycle of operation, significantly improve operating efficiency of the present invention, and then significantly reduce the production cost of product.
As further improving, described stroke sensor is three, and wherein two stroke sensors are positioned on the position of slide block near-lying mode body, and another one stroke sensor is positioned on the position of nearly 3rd cylinder of slide block; And the spacing between two stroke sensors of the same side is 2 ~ 8cm; Then in the later stage of blow molding, slide block also has one to the action of die cavity movement with blow needle, blow needle mechanism is made to have an action extruded to the tank wall around blow needle, make the tank wall density at this place relatively large, and then be beneficial to the installation of later stage reservoir port parts, make the tank wall at the parts of reservoir port this place when mounted not easily occur the situation of being out of shape, thus ensure air-tightness and the bonding strength at reservoir port place, improve stability in use and the service life of product.
