Abstract
The invention discloses a lever-accelerating/accurately-positioned air blowing mechanism applied to blow-molding dies for automobile fuel tanks, which aims to meet the demand that air needles obtain larger puncture acceleration during motion and accurately-positioned air blowing. The mechanism consists of a rotating shaft, a cylinder, a cylinder connecting piece, a swing arm, a guide pillar, a lever, an air needle, an air-needle fixing block and other parts. According to the principle of moment, the lever-accelerating mechanism obtains larger acceleration at the end with a long force arm by utilizing the cylinder to apply smaller acceleration to the end with short force arm so as to meet the demand that the air needle punctures a material base, and simultaneously utilizes the stroke control of the cylinder and the motion direction of the air needle guided by the guide pillar to accurately position air blowing so as to satisfy process conditions in blow-molding production. Therefore, products meeting requirements can be continuously and stably obtained.
Description
Technical field
The invention belongs to the vehicle fuel tank blow moulding field, be specifically related to a kind of lever that is applied in the vehicle fuel tank blow moulding tool and quicken, accurately locate inflatable body.
Background technology
Medium-sized blow molding die all is the contact-making surface places that inflatable body are arranged on two-half die, and it is small-sized or the condition of small walled that this blow molded product that just requires to be produced need satisfy.Its production procedure is that blowing material embryo gets into die cavity; Blow from material embryo edge behind the mold closing; Cool off the die sinking pickup again, this blow molding process can only be accomplished to blowing pressure less demanding or non-uniform temperature and bring the product wall thickness not exclusively evenly or to the undemanding product of safety requirements.For automotive oil tank (product size: 1425mm*395mm*315mm; The product wall thickness requires 5mm); Adopt common blow molding process; Can not instantaneous time reach the requirement of needed balanced high temperature of big wall thickness material blowing and high pressure, more can not guarantee to obtain the fuel tank product that wall thickness is even, safety coefficient is high.Therefore in order to create balanced high temperature and this working condition of high pressure blowing: the admission of blowing needle is arrived the optimum position of blowing through the material base that blow needle stings excessive wall thickness at a high speed, is the technological difficulties that exist in the blow mold field at present.
Summary of the invention
The objective of the invention is to design and a kind ofly can pass big wall thickness material fast inflatable mouth is delivered to the blow-out position of appointment, quicken, accurately locate inflatable body with the lever of the process conditions that satisfy vehicle fuel tank blow moulding production.
Above-mentioned purpose, realize through following technical scheme:
A kind of lever that is applied in the vehicle fuel tank blow moulding tool quickens, accurately locatees inflatable body; It is characterized in that: this mechanism includes holder, is disposed with cylinder, swing arm and guide pillar on the holder, and wherein cylinder is provided with cylinder connection piece; Guide pillar and holder are fixed; Be with the air tube fixed block that has air tube on the guide pillar, lever connects cylinder connection piece, swing arm and air tube fixed block through turning cylinder, between the two the arm of force after the arm of force between the above two is shorter than; The driving cylinder moves up and down; Cylinder connection piece drives lever one end, and as fulcrum, and then the other end air tube fixed block that drives lever quickens to move up and down under the guiding of guide pillar with the turning cylinder in the swing arm.
Described lever is arranged on the both sides of cylinder connection piece, swing arm, air tube fixed block, has fixed connection mechanism between the lever of both sides, makes lever construction more safely with reliable.
Described swing arm has a swing arm holder, and both are connected through turning cylinder, and swing arm is moved as fulcrum relative fixed seat with this turning cylinder after by lever drives.
The present invention applies less acceleration through cylinder at the short end of the arm of force and makes the bigger end of the arm of force obtain bigger acceleration according to lever principle, makes air tube can pass big wall thickness material base fast, has solved puncture force and has reached the excessive difficult problem of puncture force loss inadequately; Through the Stroke Control of cylinder and the guiding of guide pillar, make the inflatable mouth of air tube obtain the condition that accurate space blow-out position has satisfied blow molding process.The application of this mechanism rises to space blowing with the technology of general blow molding die blowing from the edge, makes the pressure of blowing in the die cavity can reach equilibrium moment with temperature, has reduced the cost of production and processing, has improved production efficiency; Make the research and development space of serviceability of product more open, have DEVELOPMENT PROSPECT and business development meaning widely.
Description of drawings
Fig. 1 is an operation principle sketch map of the present invention;
Fig. 2 is a structural representation of the present invention.
The specific embodiment
Below in conjunction with accompanying drawing the present invention is described further.
Like Fig. 1, shown in Figure 2; A kind of lever that is applied in the vehicle fuel tank blow moulding tool quickens, accurately locatees inflatable body, and this mechanism includes holder 1, is disposed with cylinder 2, swing arm 3 and guide pillar 4 on the holder 1; Wherein cylinder 2 is provided with cylinder connection piece 21; Guide pillar 4 is connected with holder 1, is arranged with the air tube fixed block 5 that has air tube 51 on the guide pillar 4, and lever 6 connects cylinder connection piece 21 through turning cylinder 11; Lever 6 connects swing arm 3 through turning cylinder 12, and lever 6 connects air tube fixed block 5 through turning cylinder 14.Wherein the arm of force L1 between cylinder connection piece 21 and the swing arm 3 is shorter than the arm of force L2 between swing arm 3 and the air tube fixed block 5.Lever 6 is arranged on the both sides of cylinder connection piece 21, swing arm 3, air tube fixed block 5, has the mechanism 7 of fixed connection between the lever of both sides, makes lever construction more safely with reliable.Swing arm 3 has a swing arm holder 31, and both are connected through turning cylinder 13, and swing arm 3 is driven the back by lever 6 and moves as fulcrum relative fixed seat 1 with this turning cylinder 13.
In the time of work; Drive cylinder 2; Cylinder piston passes to turning cylinder 11 through cylinder connection piece 21 with instantaneous acceleration; As fulcrum, the moment that turning cylinder 11 obtains from cylinder 2 places acts on turning cylinder 14 through lever 6 with the turning cylinder in the swing arm 3 12, make air tube fixed block 5 obtain with turning cylinder 11 oppositely and bigger acceleration; Air tube fixed block 5 drives air tube 51 and along guide pillar 4 guide direction product is punctured, and inflatable mouth is delivered to required locus; Air tube 51 begins to blow, and finishes back cooling, die sinking pickup.
