Abstract
The invention discloses a two-stage ejection device of a mould. The device comprises a mould body and is characterized in that a pin press plate is arranged on the lower portion of the mould body and a pin is arranged on the upper end face of the pin press plate; and a two-stage ejection mechanism is arranged on the upper portion of the mould body and connected with the upper portion of the pin. Furthermore, the two-stage ejection mechanism comprises a sleeve and a contraction drum, wherein the sleeve penetrates through and is fixedly connected to the upper portion of the mould body, the contraction drum is sleeved into the sleeve, the bottom of the contraction drum is connected with the middle of the mould body, and the upper portion of the pin is sleeved into the contraction drum. The device comprises the pin, the contraction drum and the sleeve which are sleeved sequentially. According to the two-stage ejection device, the structure is simple, the device is convenient to operate, a plurality of support pins are avoided, mould materials are reduced, therefore the production cost is reduced, the whole height of the mould is reduced simultaneously, and materials are greatly saved.
Description
Technical field
The invention belongs to template contral device field, specifically, relate to a kind of mould secondary liftout attachment.
Background technology
In the modern industry, be more and more higher to the processing request of parts.The processing of parts, mould are keys, and various moulds arise at the historic moment.At present, three template dies are a kind of important templates, and the quality of its design has directly determined the quality of the parts that process.Three template dies comprise A plate, B plate and C plate successively, and roughly structure is identical between them, and effect is also roughly fixing.
Secondary ejection structure in the mould, the top board pins of following that generally adopt at present combine more.Use the top board pins of following more, increased mold materials, production cost raises, so that the whole height of mould raises, has wasted a large amount of materials again.
Summary of the invention
The technical problem to be solved in the present invention is to overcome defects, and a kind of simple in structure, easy to operate and mould secondary liftout attachment of reducing waste of material, reducing production costs is provided.
For addressing the above problem, the technical solution adopted in the present invention is:
A kind of mould secondary liftout attachment comprises die ontology, it is characterized in that: the bottom of described die ontology is provided with the pin pressing plate, is provided with pin on the upper surface of pin pressing plate; Described die ontology top be provided with secondary ejecting mechanism, secondary ejecting mechanism is connected with the top of pin.
Say further:
Described secondary ejecting mechanism comprises sleeve and shrink cylinder; Sleeve runs through and is fixedly connected with the top of die ontology; Be socketed with shrink cylinder in the described sleeve, the middle part of the bottom connecting mold body of shrink cylinder; The top of socket pin in the shrink cylinder.
Owing to adopted technique scheme, compared with prior art, the present invention includes pin, shrink cylinder and the sleeve of successively socket.During the mould die sinking, pin is motionless, and ejector retainner plate drives shrink cylinder and moves, owing to pin is arranged in the shrink cylinder the inside, so template push pedal band moving sleeve and product motion.When reaching certain stroke, pin breaks away from shrink cylinder, and at this time shrink cylinder can be shunk and be injected in the sleeve, continues to eject, thereby reaches Double-ejection.The present invention is simple in structure, and is easy to operate, avoided using the top board pins of following more, reduced the use of mold materials, then reduced production cost, again so that the whole height of mould reduces, greatly saved material simultaneously.
The invention will be further described below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is the structural representation of an embodiment of the present invention.
Among the figure: the 1-sleeve; The 2-shrink cylinder; The 3-pin; 4-pin pressing plate; The 5-die ontology.
The specific embodiment
Embodiment:
As shown in Figure 1, a kind of mould secondary liftout attachment comprises die ontology 5, is generally three template dies at this die ontology 5.The bottom of die ontology 5 is provided with pin pressing plate 4, is provided with pin 3 on the upper surface of pin pressing plate 4.Die ontology 5 top be provided with secondary ejecting mechanism, secondary ejecting mechanism is connected with the top of pin 3.
In the present embodiment, secondary ejecting mechanism comprises sleeve 1 and shrink cylinder 2.Sleeve 1 runs through and is fixedly connected with the top of die ontology 5.Be socketed with shrink cylinder 2 in the sleeve 1, the middle part of the bottom connecting mold body of shrink cylinder 2, the top of shrink cylinder 2 interior socket pins 3.
During the mould die sinking, pin is motionless, and ejector retainner plate drives shrink cylinder and moves, owing to pin is arranged in the shrink cylinder the inside, so template push pedal band moving sleeve and product motion.When reaching certain stroke, pin breaks away from shrink cylinder, and at this time shrink cylinder can be shunk and be injected in the sleeve, continues to eject, thereby reaches Double-ejection.The present invention is simple in structure, and is easy to operate, avoided using the top board pins of following more, reduced the use of mold materials, then reduced production cost, again so that the whole height of mould reduces, greatly saved material simultaneously.
The present invention is not limited to above-mentioned preferred embodiment, and anyone should learn the structural change of making under enlightenment of the present invention, and every have identical or akin technical scheme with the present invention, all belongs to protection scope of the present invention.
