Abstract
The utility model relates to a mold locking device for a plastic blowing hollow former, which comprises a U-shaped body; two pull rods can be connected with two vertical walls of the body in parallel, a fixed mold plate can be arranged in the inner side of a vertical wall of the body, and a movable mold plate can be glidingly sheathed on two pull rods; a support bracket on the front and the rear parts of the movable mold plate can be glidingly sheathed with the two pull rods, and the support bracket is provided with a sleeve hole glidingly sheathed with the pull rods of the former; the body is provided with a mold locking driver connected with the movable mold plate, and an opening and closing synchronous rack and gear mechanism of the mold plate can be arranged between the movable mold plate and the body. The mold locking device for the plastic blowing hollow former has the advantages of high rigidity, easy mold assembling and disassembling, convenient charging and discharging, and small size.
Description
The utility model belongs to the plastic molding equipment technical field, more particularly relates to the equipment of blowing plastic products in model.
Existing locked mode frame is the assembling lock mould bases that connects template and support plate with three or two pull bars, and is easy to manufacture, but the rigidity deficiency, local locked mode is not tight, loads and unloads the mould inconvenience simultaneously, and overall volume is big.
The purpose of this utility model is that a kind of good rigidly will be provided, and mould handling is easy, the clamping apparatus of the plastic blown blow moulding machine that volume is little.
The technical solution of the utility model is: it comprises a Qian shape main body, and two pull bars are connected on two walls of main body abreast, and solid plate is installed on a wall inboard of main body, and moving platen slides on two pull bars; One carriage is at the forward and backward of moving platen and two pull bar sliding sleeves, and carriage is provided with and the slide bar of the make-up machine trepanning of sliding sleeve mutually; Device has the locked mode drive unit that is connected with moving platen on the main body; Device has the synchronous rack and pinion mechanism of template folding between moving platen and the main body.
Carriage of the present utility model bottom also can be provided with oil drain pan, oozes the oil that drops down to accept the lubricant housings.
Locknut drive unit of the present utility model can adopt electric motor driven ball screw transmission mechanism, also can adopt hydraulic jack drive unit or cylinder driver.
Compared with prior art, the utlity model has following advantage:
1, main body adds two pull bars, forms the locked mode frame of good rigidly, particularly make things convenient between template mould install and connect material, inloading part, pull bar as the slide rail of moving platen and the backbar of whole device, makes compact conformation again, volume is little;
2, the preceding supporting-point of carriage position between two templates, the most effective bearing inserted a pressure, back supporting-point position is suitable, makes whole device stability powerful, make the total length of structure and support reasonable.
The utility model is described in further detail below in conjunction with embodiment and accompanying drawing.
Fig. 1 is a structure front elevational schematic of the present utility model;
Fig. 2 is structure schematic top plan view of the present utility model (not expressing the locked mode drive unit among the figure).
1, two pull bar of Qian shape main body, the 2 usefulness nuts that the utility model has an integral body to cast out are fixed on two walls of main body 1 abreast, and solid plate 3 is installed on a wall inboard of main body 1, and moving platen 4 slides on two pull bars 2.The forward and backward supporting sliding sleeve of one L shaped carriage 7 usefulness supports two pull bars 2, two pull bar sections of preceding supporting position point midway between solid plate 3 and moving platen 4, two pull bar sections of supporting position, back close main body 1 wall after moving platen 4, upper and lower two parallel slide bars 8 of carriage 7 and make-up machine are sliding sleeve mutually, two slide bars 8 are perpendicular to two pull bars 2, and whole clamping apparatus is suspended on also can be along slide bar 8 slippages on the slide bar 8.Servomotor 5 is housed on the main body 1, and the nut that servomotor 5 drives the ball screw transmission mechanism rotates, and the screw mandrel 6 that nut transmission and moving platen 4 are fixed together, screw mandrel 6 push away or spur template 4 and slide along two pull bars 2.One tooth bar 9 of the synchronous rack and pinion mechanism of locked mode folding is installed on the moving platen 4, and another tooth bar 10 is installed on the main body 1, and idler gear 11 is installed on the carriage 7.During work, the nut that servomotor 5 drives the ball screw transmission mechanism rotates, and nut drive lead screw 6 promotes template 4 and shifts to solid plate 3 along pull bar 2, simultaneously, synchronous rack and pinion mechanism makes main body 1 be inconjunction with solid plate 3 and synchronously moves in opposite directions, until the locking mould.During rapping, servomotor 5 counter-rotating, solid plate 3 and moving platen 4 are opposite to separating by with locked mode the time.Carriage 7 and two pull bars 2, carriage 7 and two slide bars 8, two pull bars 2 and moving platen 4 mutually the lubricating oil at sliding sleeve place can ooze and drop down, on carriage 7, have oily runner and oil drain pan 12, avoid the oil contamination environment.
Claims (4)
1, a kind of plastic blown blow moulding machine clamping apparatus, it is characterized in that: it comprises a Qian shape main body, article two, pull bar is connected on two walls of main body abreast, solid plate is installed on a wall inboard of main body, and moving platen slides on two pull bars, one carriage is at the forward and backward of moving platen and two pull bar sliding sleeves, carriage is provided with and the slide bar of the make-up machine trepanning of sliding sleeve mutually, device has the locked mode drive unit that is connected with moving platen on the main body, and device has the synchronous rack and pinion mechanism of template folding between moving platen and the main body.
2, clamping apparatus according to claim 1 is characterized in that support support before the carriage lives two pull bar sections of point midway between solid plate and the moving platen.
