Abstract
The invention discloses mould legs of an injection mould. The mould legs are arranged between a movable mould plate (1) and a moving clamping plate (2), and an ejection plate (4) is also arranged between the movable mould plate (1) and the moving clamping plate (2). The mould legs (3) of the injection mould are arranged on both sides of the ejection plate (4), square grooves (5) are formed in the outer sides of the mould legs (3) of the injection mould, the inner sides of the mould legs (3) of the injection mould are small on both sides and large in the centers,the inner sides of the mould legs (3) of the injection mould face to the ejection plate (4), and the ends, in which the square groove (5) are formed, of the mould legs (3) of the injection mould face the moving clamping plate (2). Through the above manner, the installation and fixing of a vertical movable mould and an injection machine can be achieved, the bearing area of the mould legs is increased, the motion stability of the ejection plate is improved, the cost of mould is reduced, and the problem of difficult selection of the table of the injection machine is solved at the same time. The mould legs of the injection mould are particularly suitable for injection of large-size formed products or ejector plates equipped with finger cams, pull rods and other mould parts and have a good application prospect and practical significance.
Description
Technical field
The present invention relates to injection mold mechanism field, particularly relate to a kind of injection mould mould pin.
Background technology
Injection moulding is under high pressure conditions, plastic melt to be arrived in closed die cavity with high speed injection, obtains and the on all four plastic products of die profile after pressurize, cooling and shaping.Injection mold is the important process equipment during plastic injection is produced, and in its structure, generally six large systems, consists of, and forms respectively the fixed half and moving half part of mould, and wherein solid plate, moving platen, mould pin are the most basic structure component parts.Mould pin is called again square iron, is generally placed under moving platen or under gripper shoe, and Bottom clamp plate is generally installed by mould underfooting side, and upper and lower liftout plate is installed respectively on Bottom clamp plate, and mould pin, moving platen/gripper shoe and Bottom clamp plate form the space that ejects of liftout plate.After die assembly, dynamic model part will be fixed on and in injector, realize the motion of opening and closing mould.For I-shaped mould, generally by foundary weight, Bottom clamp plate being fixed on to the installation that injector motion side realizes dynamic model and injector fixes, while adopting I-shaped mould, due to Bottom clamp plate, size is larger than moving platen in the longitudinal direction, thereby forms ledge arrangement with mould pin, so that the installation of foundary weight and fixing, but this has increased the dimensions of mould bases virtually, cause manufacturing cost to increase, especially for large mold, because the increase of mould bases size even causes the selection difficulty of injector board.Simultaneously, traditional mould pin form is regular cuboid piece material, thereby liftout plate form is also regular rectangle plate, while the parts such as taper pin pull bar being installed on some moulding occasion especially moulding massive article or liftout plate, must increase liftout plate size, otherwise can cause the pin-and-hole that respectively resets, push pedal pilot hole on liftout plate, stop pin-and-hole, limit pin hole, trip bolt hole and taper pin tie rod hole etc. and interfere, but this strengthens die cost and board tonnage virtually, cause and produce waste.
Therefore, for solving above-mentioned mould installation requirements and for reducing costs the conflict that reduces as far as possible die size in injector, mould leg structure is improved, make it can meet the installation of mould in injector, can suitably reduce again the overall structure size of mould.
Summary of the invention
The technical problem that the present invention mainly solves is to provide a kind of injection mould mould pin, while solve adopting straight body mode structure to carry out injection moulding to produce, owing to being provided for the lug of fixing foundary weight on Bottom clamp plate, cannot not realize the fixing problem of dynamic model; The mould pin of this version can increase mould pin Area of bearing, improves and ejects location and eject robust motion; Can significantly reduce die cost, overcome injector board and select difficult problem, and improve die life to a certain extent, be particularly useful for being provided with on moulding massive article or liftout plate the injection moulding occasion of the mould parts such as taper pin pull bar, there is good application prospect and practical significance.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of injection mould mould pin is provided, be arranged between moving platen and Bottom clamp plate, between moving platen and Bottom clamp plate, be also provided with liftout plate, described a kind of injection mould mould pin is arranged on liftout plate both sides, described a kind of injection mould mould outside of foot has square groove, and two, inner side of injection mould mould pin is little broad in the middle, and the inner side of injection mould mould pin is towards liftout plate; One end that described a kind of injection mould mould pin has square groove is towards Bottom clamp plate.
Preferably, described injection mould mould pin is provided with two pairs of screw holes.
The invention has the beneficial effects as follows: the installation that the present invention can realize straight body mould dynamic model and injector for injection moulding production is fixed, and can increase mould pin Area of bearing simultaneously, improves liftout plate robust motion.
Accompanying drawing explanation
Fig. 1 is the perspective view of a kind of injection mould mould of the present invention pin;
Fig. 2 be shown in a kind of assembly structure schematic diagram of injection mould mould pin;
In accompanying drawing, the mark of each parts is as follows: 1, moving platen; 2, Bottom clamp plate; 3, injection mould mould pin; 4, liftout plate; 5, square groove.
The specific embodiment
Below in conjunction with accompanying drawing, preferred embodiment of the present invention is described in detail, thereby so that advantages and features of the invention can be easier to be it will be appreciated by those skilled in the art that, protection scope of the present invention is made to more explicit defining.
Refer to Fig. 1 and Fig. 2, the embodiment of the present invention comprises:
A kind of injection mould mould pin, be arranged between moving platen 1 and Bottom clamp plate 2, between moving platen 1 and Bottom clamp plate 2, be also provided with liftout plate 4, described a kind of injection mould mould pin 3 is arranged on liftout plate 4 both sides, described a kind of injection mould mould pin 3 outsides have square groove 5, one end that described a kind of injection mould mould pin 3 has square groove 5 is towards Bottom clamp plate 2, by briquetting, just dynamic model can be arranged on to the realization of injector motion side opens, matched moulds motion, two, inner side of injection mould mould pin 3 is little broad in the middle, and the inner side of injection mould mould pin 3 is towards liftout plate 4, liftout plate 4 is also done corresponding architecture advances near the side of injection mould mould pin 3, formation two is large, middle little " I-shaped " structure, this improvement can increase mould pin Area of bearing, improve the robust motion of liftout plate, described injection mould mould pin 3 is provided with two pairs of screw holes, realizes respectively fixing of injection mould mould pin 3 and Bottom clamp plate 2 and being connected and fixed of injection mould mould pin 3 and moving platen 1.
The present invention can realize the installation of straight body mould dynamic model and injector and fix, and can increase mould pin Area of bearing simultaneously, improves liftout plate robust motion; Can significantly reduce die cost, overcome injector board and select difficult problem, and improve die life to a certain extent, be particularly useful for being provided with on moulding massive article or liftout plate the injection moulding occasion of the mould parts such as taper pin pull bar, there is good application prospect and practical significance.
