Abstract
The utility model relates to a bidirectional closing mould stretching blow molding machine, which is composed of a machine frame, a mould closing mechanism arranged in the machine frame, a mould plate connected with the mould closing mechanism, a stretching blow mechanism arranged on the mould plate; the mould closing mechanism can be used for driving a connecting plate through a piston rod of a mould closing air cylinder arranged in the machine frame, the connecting plate can be connected with a front and a rear movable pull and push plates, the movable pull and push plates can be used for driving the mould plate through a connecting rod, the lower end of the mould plate can be connected with the connecting rod, the machine frame is provided with a chute, and the lower end of the connecting rod is matched with the chute. The bidirectional closing mould stretching blow molding machine can be used for driving the mould plate using the movable pull and push plates through the connecting rod, saves complex structures, such as a fixed mould plate, the connecting rod, etc. has the advantage of large mould opening, can be favorable for operation, has convenience, safety, etc.
Description
The utility model relates to the process equipment of plastic packaging containers, particularly relates to the stretch blowing machine of two-step method production polyester bottles, is mainly used in to produce mineral water bottle, oil bottle and the water dispenser plastic hollow vessels such as bottle that are filled with water.
Use injection, stretch-blow two-step method production plastic hollow vessel, its capital equipment is injection machine, heater and stretch blowing machine.Described stretch blowing machine is by frame, template, the clamping mechanism of folding template, be installed in Stretch and Blow Mechanism on the template etc. form.In existing stretch blowing machine, its template is divided into fixed form and collapsible form, fixed form is two, in the middle of two fixed forms a collapsible form is arranged, three templates are connected by four guide pillars, and Stretch and Blow Mechanism is installed in wherein on the template, mould of plastics is positioned on template one side during work, prefabricated plastic pipe is put into mould, after machine-shaping, from mould, take out product.Because a collapsible form is unidirectional (one-sided) die sinking, spacing is little, puts, inconvenient operation, particularly larger container when getting workpiece, as oil bottle etc., takes out difficulty, and is dangerous.Be complex structures such as template, guide pillar on the other hand, processing time consuming is many, the installation and maintenance trouble, and volume is big, the expense height.
The purpose of this utility model provides a kind of two-way locked mode, and the die sinking spacing is big, helps operation and the stretch blowing machine of simply constructed production hollow plastic container.
The technical scheme that the utility model reversible lock die drawing is stretched blow moulding machine is: by frame and the clamping mechanism that is installed in the frame; the template that connects clamping mechanism; and be installed in Stretch and Blow Mechanism on the template etc. form; it is characterized in that described clamping mechanism is mounted in the piston rod drive gusset piece of the locked mode cylinder in the frame; gusset piece links to each other with forward and backward two movable drawing plates; movable drawing plate drives template through connecting rod; connect pull bar under the template; chute is arranged in frame, matches with the groove of living in the lower end of pull bar.
The utility model discloses a kind of reversible lock die drawing and stretch blow moulding machine, compared with the prior art, have following characteristics: the one, replaced all clamping mechanisms by movable drawing plate and connecting rod, substitute parts in addition such as fixed form, collapsible form and guide pillar with two templates, simplify the structure; The 2nd, because of two-way die sinking, locked mode, the spacing of two moulds is increased, help pipe and get bottle, easy to operate, safety is particularly useful for bulk container production; The 3rd, volume-diminished, cost reduces.
Fig. 1 is that the utility model reversible lock die drawing is stretched the blow moulding machine structural representation;
Fig. 2 is that the utility model reversible lock die drawing is stretched blow moulding machine A to schematic diagram.
Below in conjunction with Fig. 1-Fig. 2 embodiment of the present utility model is done detailed explanation.
1, frame; 2, locked mode cylinder; 3, piston rod; 4, guide rod; 5, movable drawing plate; 6,8, connecting rod; 7,9, coupling bar; 10, template; 11, Stretch and Blow Mechanism; 12, template is in die opening state; 13, connecting rod is in die opening state; 14, movable drawing plate top dead centre (in mode-lock status); 15, movable drawing plate lower dead center (in die opening state); 16, gusset piece (position when locked mode); 17, gusset piece (position when die sinking); 18, pull bar; 19, roller; 20, chute.
The utility model relates to the equipment of producing plastic containers, a frame 1 is arranged in the bottom, locked mode cylinder 2 is installed in the frame 1, piston rod 3 in the locked mode cylinder 2 connects gusset piece 16,17, drive forward and backward two movable drawing plates 5 by gusset piece, described forward and backward be with respect to the people the operation the position, movable drawing plate 5 two symmetries, last peace connecting rod 6,8, connecting rod is generally 4 groups 8, and as shown in Figure 2, the other end of connecting rod 6,8 connects coupling bar 7,9, be connected on the template 10 template 10 installation molds again.Template 10 cylinder lever connecting rods 18 are shaped on the slideway of chute 20 in frame 1, following roller installed 19 of pull bar 18 moves in chute by roller 19.Movable drawing plate 5 upper and lower motions can be carried out along guide rod 4.Be the die opening state locations of structures shown in the chain-dotted line among Fig. 1, Fig. 2, as template 12, connecting rod 13 and gusset piece 17 etc., a lot of for the pattern of frame, the Stretch and Blow Mechanism 11 on the template is prior aries, does not describe in detail.
