Abstract
The utility model relates to a mould opening/closing mechanism of a clamp type template for a plastic drawing blower, which is provided with a rotary machine frame in which a main shaft connected with a left template and a right template is arranged. The outer walls of the left template and the right template are provided with connecting rings connected with two connecting rods, and the connecting rods are connected with the driving mechanism for an opening/closing mould. The other sides of the left template and the right template are provided with mould locking mechanisms. The driving mechanism for an opening/closing mould is a shifting arm connected with the left connecting rod and the right connecting rod and are connected to a mould opening shaft which is arranged in the machine frame and is downwards connected with a twisting rod; the twisting rod is connected with a bearing through a pin, and the bearing contacts both sides of the guide rail slot on a slotted mould opening guide rail which is installed on a fixed machine base. A plurality of groups of left templates, right templates and mechanisms driving the left templates and the right templates to open or close are arranged on the same rotary machine frame; when the left templates and the right templates rotate with the machine frame to the position of the fixed slotted mould opening guide rail, the bearing runs along the guide rail slot to open or close the left templates and the right templates.
Description
Technical field
The utility model relates to the clasp mould mechanism of clamp type templates of machine for drawing and blowing plastic, belongs to the plastics machinery field.
Background technology
Adopt notes, stretch blow processing hollow plastic container, need plastic draw-blow machine.Plastic draw-blow machine can be divided into translation opposite opened template or jaw type folding template; the characteristics of jaw type folding template are; side in left and right two templates is fixed by main shaft mutually, so the folding of template is to open or closure at opposite side, the clasp mould mechanism that drives template also is rotation formula.Prior art is that the connecting rod that adopts the push-and-pull cylinder to drive moves on a center line in the folding to clamp type templates on the plastic draw-blow machine, cylinder drivening rod structure in a straight line is very long like this, occupation space is bigger, particularly just can't place for the multistation stretch blow machine of rotation.
Summary of the invention
The purpose of this utility model is in order to overcome the shortcoming of prior art, provides a kind of lead agency short, and is applicable to the clasp mould mechanism of the clamp type templates of machine for drawing and blowing plastic that rotary multistation stretch blow machine is supporting.
The technical scheme of the clasp mould mechanism of the utility model clamp type templates of machine for drawing and blowing plastic is: the frame that a rotation is arranged; main shaft is installed in frame; main shaft connects left template and right template; a left side; the outer wall of right template is shaped on connecting ring; connecting ring links to each other with two connecting rods; two connecting rods connect to be opened; the lead agency of matched moulds; on a left side; the opposite side of right template is installed clamping mechanism; its described opening; the lead agency of matched moulds is and a left side; the moving arm that right connecting rod links to each other; moving arm is connected on the die sinking axle; the die sinking axle is installed in the frame; the die sinking axle connects torsional pole down; torsional pole distribution connection bearing, bearing contacts with the guide-track groove both sides that the groove mould opening guide rail is arranged, and has the groove mould opening guide rail to be installed on the fixing support.The mechanism of the left and right template of the technical program and the left and right template folding of drive has many groups (being multistation stretch blow machine) to be installed on the same frame, frame is work in rotating (must rotate), and mould opening guide rail has groove and be installed on the support, and it is fixing (must be fixing) that support does not rotate.When left and right template has run to groove mould opening guide rail position along with the frame rotation, bearing enters in the guide-track groove of groove mould opening guide rail, move along guide-track groove, guide-track groove is pre-designed track, bearing contacts with rail walls in orbital motion, the bearing distribution reacts on torsional pole and drives the rotation of die sinking axle, and the die sinking axle drives moving arm and makes left and right template opening and closing by two connecting rods.So the opening and closing of left and right template do not need spcific power, be to rely on mechanical Contact Transmission to drive.

The specific embodiment
The utility model discloses a kind of clasp mould mechanism of clamp type templates of machine for drawing and blowing plastic; be specially adapted to multistation stretch blow machine; the frame 1 that a rotation is arranged; many group Stretch and Blow Mechanisms (but in practical product also can one group) are installed on the frame; every group of Stretch and Blow Mechanism all installed main shaft 7 in frame 1; main shaft connects left template 3 and right template 5; connected mode can be as Fig. 2; Fig. 3 institute formula; a left side; the outer wall of right template is shaped on connecting ring 4; 6 (ears); a connecting ring and a left side; right two connecting rods 9; 10 link to each other; said structure and prior art are basic identical; two connecting rods connect to be opened; the lead agency of matched moulds; on a left side; the opposite side of right template is installed clamping mechanism 8; its major technology is characterised in that described opening; the matched moulds lead agency is and a left side; right connecting rod 9; 10 moving arms 11 that link to each other; connecting pin 2 is arranged; by the moving arm drivening rod; the overall length of machine is shortened; compact conformation; if the multistation volume dwindles greatly; moving arm is connected on the die sinking axle 12; die sinking axle 12 is installed in the frame 1; as Fig. 1; shown in Figure 4; the die sinking axle connects torsional pole 13 12 times; torsional pole 13 distributions 14 connection bearings 15; also can be in actual product without bearing; and use the roller of other structure, but bearing is reliable for effect, is again existingly can join parts; bearing contacts with guide-track groove 18 both sides that groove mould opening guide rail 16 is arranged, and has the groove mould opening guide rail to be installed on the fixing support 17.Have the groove mould opening guide rail can have mould opening guide rail 16 ' with mould closing guide rail 16 "; as shown in Figure 5; be installed in respectively on the support 17 fixing below the running route; but also can use a channel-section steel to make; being positioned on fixedly on the support, is to adopt operating machinery to contact transmission power to come the opening and closing mould fully by two guide rails.Be that this mechanism is that the track that utilizes left and right guide rail side to open 16 motions of (closing) mould guide rail promotes die sinking axle 12 rotation drive moving arms 11 through bearing 15, pin 14, torsional pole 13, rotate the motion that drives left connecting rod 9, right connecting rod 10 through moving arm 11.A left side template 3, right template 5 go here and theres dress together under the connection of main shaft 7, it opens or closes is that left and right connecting rod 9,10 is controlled, and are used for that stretch blow work is carried out and end-of-job aftershaping plastic bottle automatic demoulding.So, be the start-up time of the lead agency of opening and closing mould when left template 3 runs to folding mould guide rail 16 positions when rotated with right template 5, bearing 15 enters guide-track groove 18, bearing distribution 14 is impelled torsional pole 13 to reverse to drive die sinking axle 12 and is reversed, be connected moving arm 11 on the die sinking axle 12 immediately following reversing, drive is installed in the left connecting rod 9, the right connecting rod 10 that connect with connecting pin 2 on the moving arm 11 and moves horizontally, and drives opening or closure of left template 3, right template 5.
