Description

A kind of injection mould mould pin
Technical field
The utility model relates to a kind of injection mould mould pin, belongs to injection mold manufacturing technology field.
Background technology
Along with advancing by leaps and bounds of plastics industry, the demand of mould of plastics sharply increases.In order to adapt to, the size of plastic products becomes more diverse, shape is day by day complicated and the demand of attractive in appearanceization of incrustation, and mould of plastics is just towards diversified, complicated, precise treatment and multi-cavity future development.
Injection moulding is a kind of main moulding process and the method for plastic part, 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.At the larger goods Shi of moulding ﹐, because thereby causing moulding Que Xian ﹐, the bent Bian Xing of may the Fa raw Wan of the ﹐ male model plate ﹐ Xia higher injection pressure of the span compare great ﹐ between two mould pin generally on mould, increases support part into Xie this Wen Ti ﹐ that determines, as mould pin and support column.Mould pin is generally installed under moving platen (or gripper shoe), and Bottom clamp plate is installed by mould underfooting side, and upper and lower liftout plate is installed respectively on Bottom clamp plate, and mould pin, moving platen (or gripper shoe) and Bottom clamp plate form the space that ejects of liftout plate.After die assembly, dynamic model is partly fixed on injector motion parts and realizes the motion of opening and closing mould.For I-shaped mould, generally by foundary weight, Bottom clamp plate is fixed in injector, to realize the installation of dynamic model and injector, fix, 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.Meanwhile, traditional mould pin and Bottom clamp plate are split type form, are connected by screw fixingly after assembling, to form, eject space, and this has also increased die manufacturing cost virtually, cause and produce waste.
Utility model content
The utility model object is in order to overcome the deficiencies in the prior art, to provide a kind of to conflict with the demand that reduces as far as possible die size in order to reduce costs for solving the installation requirements of above-mentioned mould in injector and ejecting space demand, the utility model improves mould leg structure, make it can meet the installation of mould in injector, can guarantee to eject again the realization of motion, and a kind of injection mould mould has been proposed the overall structure size that reduces to a great extent mould bases.
For achieving the above object, the technical solution adopted in the utility model is: a kind of injection mould mould pin, and described mould pin is hexahedral rectangular structure, at a side and the close mould foot plate surface place of described mould pin, has a rectangular slot; On described mould pin, be also provided with a shoulder; Described shoulder is at the opposite side of described rectangular slot side of living in and be connected with mould foot plate surface.
Further improved as the utility model, described shoulder thickness is 25-40mm.
Due to the utilization of technique scheme, the utility model compared with prior art has following advantages:
A kind of injection mould mould pin of the utility model scheme, by the architecture advances to mould pin, can realize the installation of straight body mould dynamic model and injector fixes, simultaneously realize and under prerequisite, reduce mould bases overall structure size guaranteeing to eject motion, can significantly reduce die cost simultaneously, overcome injector board and select difficult problem, be particularly useful for the injection moulding occasion of moulding massive article, there is good application prospect and practical significance.
Accompanying drawing explanation
Below in conjunction with accompanying drawing, technical solutions of the utility model are described further:
Accompanying drawing 1 is the structure chart of injection mould mould pin of the present utility model;
Accompanying drawing 2 is the mounting structure figure of injection mould mould pin of the present utility model;
Wherein: 1, moving platen; 2, mould pin; 3, rectangular slot; 4, shoulder; 5, bottom surface; 6, screw; 7, support column; 8, upper ejector plate; 9, lower liftout plate; 10, return pin.
the specific embodiment
Below in conjunction with drawings and the specific embodiments, the utility model is described in further detail.
Be a kind of injection mould mould pin described in the utility model as shown in Figure 1, mould pin 2 is hexahedral rectangular structure, at a side and the close mould foot plate surface place of mould pin 2, has a rectangular slot 3; On mould pin 2, be also provided with a shoulder 4; Shoulder 4 is at the opposite side of described rectangular slot 3 sides of living in and be connected with mould foot plate surface 5.
As shown in Figure 2, mould pin 2 is connected and fixed by screw 6 and moving platen 1; Some support columns 7 are set below moving platen 1 increases the Area of bearing of moving platen 1, and upper and lower liftout plate 8,9 is connected and fixed by screw, return pin 10 is installed on upper ejector plate 8 and ejects reset.
The mould pin of this version is designed to inner side with the monolithic construction of shoulder 4 by Bottom clamp plate of the prior art and mould pin, by briquetting, snap in that rectangular slot 3 is interior is fixed on injector motion side by mould pin 2, to realize the opening and closing mould motion of dynamic model part, thereby the installation that realizes straight body mould and injector is fixed, can guarantee to eject space and eject robust motion, and can reduce the overall structure size of mould bases simultaneously; The thickness of shoulder 4 is answered proof strength demand, generally in 30mm left and right.
Below be only concrete exemplary applications of the present utility model, protection domain of the present utility model is not constituted any limitation.All employing equivalents or equivalence are replaced and the technical scheme of formation, within all dropping on the utility model rights protection scope.
