Abstract
The utility model discloses a pneumatic secondary demoulding mechanism to the spring of solving spring secondary demoulding mechanism became invalid easily, problem that economic practicality is poor. Pneumatic secondary demoulding mechanism includes the backing plate and fixes the core on backing plate upper portion, but the backing plate top is equipped with the shaping push pedal of up -and -down motion, and it has vertical through -hole to open in the shaping push pedal, and the through -hole can separate with the core during drawing of patterns, its characterized in that, and it has vertical air vent to open at the middle part of backing plate, air vent lower extreme and air compressor machine link to each other, the upper end communicates with each other with the through -hole.
Description
Technical field
The utility model relates to a kind of pneumatic secondary demolding mechanism.
Background technology
Mould emptier is also known as ejecting mechanism; realize the mechanism that plastic deviates from from the die cavity of mould; existing mould emptier is divided into: simple (once) mould emptier, sequence demoulding mechanism and secondary demolding mechanism; secondary demolding mechanism is also known as two-step ejector mechanism or secondary ejecting mechanism; because; along with the development of plastics industry; the shape of plastic becomes increasingly complex; for the plastic that some are complex-shaped; after a stripping action completes; plastic still can not be deviate from from die cavity, just needs increase stripping action.At present, what secondary demolding mechanism generally adopted is spring secondary demolding mechanism, but easily loses efficacy because of spring Long-Time Service, needs frequent replacing in use procedure, therefore not economic and practical.
Utility model content
The utility model is intended to provide a kind of pneumatic secondary demolding mechanism, easily loses efficacy with the spring solving spring secondary demolding mechanism, the problem of economic and practical difference.
Pneumatic secondary demolding mechanism in this programme; comprise backing plate and the core being fixed on backing plate top; the moulding push plate that can move up and down is provided with above backing plate; moulding push plate has vertical through hole, during a demoulding, through hole can be separated with core, it is characterized in that; vertical passage is had at the middle part of backing plate; passage is provided with air valve, and described passage lower end is connected with air compressor machine, and upper end communicates with through hole.
The utility model has the advantage of: first, goods to move upward disengaging core by moulding push plate, complete a demoulding, but the goods after a demoulding are still stayed on moulding push plate, at this moment open air valve, and compressed air enters through hole from breather pipe, blow off goods moulding push plate, completes the secondary demoulding.This programme, compared to spring secondary demolding mechanism, overcomes spring and easily lost efficacy and need the frequent problem changed, have more economic and practical.
Further, core and through hole are provided with two groups, and are oppositely arranged centered by described passage, and the upper end of passage is provided with two holes, and two holes communicate with two through holes respectively.Core and through hole all arrange two groups, and the die cavity of corresponding mould also arranges two groups, and one-shot forming two goods, can improve shaping efficiency, and the upper end of passage is provided with two holes, can give respective through hole air feed respectively.
Further, two hole is V-shaped is symmetrical arranged, and can guarantee that the throughput of both sides through hole is even.
Further, backing plate is fixed with vertical guide pillar, moulding push plate has pilot hole, during a demoulding, guide pillar and pilot hole depart from.During a demoulding, by pilot hole and guide pillar, moulding push plate is played to the effect of motion guide, the demoulding is more stable.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, the utility model is described in further detail:
Reference numeral in Figure of description comprises: goods 1, moulding push plate 2, core 3, guide pillar 4, backing plate 5, breather pipe 6.
Embodiment is substantially as shown in Figure 1: the pneumatic secondary demolding mechanism of the present embodiment, backing plate is positioned at bottom, and backing plate top is provided with two groups of cores, and core is threaded with backing plate.Backing plate is fixed with vertical guide pillar, and the upper end of guide pillar has sphere.Have vertical passage at the middle part of backing plate, passage is provided with air valve, passage lower end is connected with air compressor machine.
Moulding push plate is positioned at the top of backing plate, and can move up and down, and moulding push plate has vertical through hole, and through hole has two groups, and often organize through hole and be up big and down small ladder hole, the core of the present embodiment and through hole are all oppositely arranged centered by described passage.
The upper end of passage is provided with two holes, and two hole is V-shaped is symmetrical arranged, and two holes communicate with two through holes respectively.
During a demoulding, through hole can be separated with core, and moulding push plate has pilot hole, and during a demoulding, guide pillar and pilot hole depart from.During the secondary demoulding, open air valve, in passage, pass into compressed air, goods can be separated with moulding push plate.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the prerequisite not departing from the utility model structure, some distortion and improvement can also be made; these also should be considered as protection domain of the present utility model, and these all can not affect effect and the practical applicability of the utility model enforcement.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. record the content that may be used for explaining claim.
