Abstract
The utility model discloses a kind of pop-up type line position core-pulling mechanism, comprise front mould A plate, rear mold B plate, rear mold support fixed head, the bottom of described front mould A plate is connected with the top of rear mold B plate; Be provided with rear core rod in described rear mold B plate, this rear core rod is provided with slide block; Described rear mold supports fixed head and is connected with the bottom of rear mold B plate, and rear mold support fixed head is provided with shovel base, and described shovel base is connected with slide block.The utility model uses the mechanical form that flicks to loose core to realize line position, spacing spacing that a lot of oil cylinder and oil cylinder mechanism must have can be saved, induction of signal controls and identification, backhoe mechanism etc., simplify mechanism, save cost energetically, eliminated the maintenance of oil cylinder, can avoid polluting simultaneously, environment purification, neat and tidy, is beneficial to workman's operation, facilitates the maintenance in later stage.
Description
Technical field
The present invention relates to technical field of mold, having particularly related to a kind of pop-up type line position core-pulling mechanism of the plastics injection mould for having the front mould of more than 2 or rear mold tunnel type to loose core.
Background technology
Increasing plastics injection mould is being had to need to do multiple core-pulling mechanism at present, traditional method is exactly the core-pulling mechanism directly becoming tunnel type, adopt hydraulic oil cylinder driving, but adopt loose core of oil cylinder can bring very large oil pollution, it is many unfavorable to bring to production environment and workman's operation.Moreover, if one set of die has multiple similar means just directly to cause oil cylinder increasing number simultaneously, signal control and Stroke Control are made troubles, probably exceeds the Signal analysis upper limit of injection machine, oil cylinder cost is large simultaneously, and care and maintenance is also a problem.
Summary of the invention
For the deficiency that prior art exists, object of the present invention just there are provided a kind of pop-up type line position core-pulling mechanism, the mechanical form that flicks is used to loose core to realize line position, spacing spacing that a lot of oil cylinder and oil cylinder mechanism must have can be saved, induction of signal controls and identification, backhoe mechanism etc., simplify mechanism, save cost energetically, eliminate the maintenance of oil cylinder, can avoid polluting simultaneously, environment purification, neat and tidy, is beneficial to workman's operation, facilitates the maintenance in later stage.
To achieve these goals, the technical solution used in the present invention is such: a kind of pop-up type line position core-pulling mechanism, and comprise front mould A plate, rear mold B plate, rear mold support fixed head, the bottom of described front mould A plate is connected with the top of rear mold B plate; Be provided with rear core rod in described rear mold B plate, this rear core rod is provided with slide block; Described rear mold supports fixed head and is connected with the bottom of rear mold B plate, and rear mold support fixed head is provided with shovel base, and described shovel base is connected with slide block.
As a kind of preferred version, described front mould A plate and rear mold B plate are by mold base shutter snapping.
As a kind of preferred version, described shovel base is provided with T-shaped dovetail groove.
As a kind of preferred version, described front mould A plate, rear mold B plate, rear mold support on fixed head and are also provided with sear mechanism.
As a kind of preferred version, described rear mold B plate is provided with inductive pick-up.
As a kind of preferred version, described rear mold B plate and rear mold support between fixed head and are provided with square lead.
Compared with prior art, beneficial effect of the present invention: the present invention uses the mechanical form that flicks to loose core to realize line position, spacing spacing that a lot of oil cylinder and oil cylinder mechanism must have can be saved, induction of signal controls and identification, backhoe mechanism etc., simplify mechanism, saved cost energetically, eliminate the maintenance of oil cylinder, can avoid polluting, environment purification, neat and tidy simultaneously, be beneficial to workman's operation, facilitate the maintenance in later stage.
Accompanying drawing explanation
Fig. 1 is structural representation of the present invention;
Fig. 2 is the connection diagram that in the present invention, rear core rod and rear mold support fixed head;
Fig. 3 is the mould product structural representation in the embodiment of the present invention.
Detailed description of the invention
Below in conjunction with specific embodiment, the invention will be further described.Following examples only for technical scheme of the present invention is clearly described, and can not limit the scope of the invention with this.
Embodiment:
As shown in Figure 1, a kind of pop-up type line position core-pulling mechanism, comprise front mould A plate 1, rear mold B plate 2, rear mold support fixed head 3, described front mould A plate 1, rear mold B plate 2, rear mold support on fixed head 3 and are also provided with sear mechanism 9; The described bottom of front mould A plate 1 and the top of rear mold B plate 2 are connect by mold base shutter 7 snapping; Described rear mold B plate 2 is provided with inductive pick-up 10; Described rear mold B plate 2 and rear mold support between fixed head 3 and are provided with square lead 11; As shown in Figure 2, in described rear mold B plate 2, be provided with rear core rod 4, this rear core rod 4 is provided with slide block 5; Described rear mold supports fixed head 3 and is connected with the bottom of rear mold B plate 2, and rear mold support fixed head 3 is provided with shovel base 6, and described shovel base 6 is provided with T-shaped dovetail groove 8 and is connected with slide block 5.During concrete enforcement, plastic mould product 12 as shown in Figure 3, during the single cave injection moulding of this mould product 12 rear mold just have core-pulling mechanism A on 3 directions to, B to, C to, and the batch of reality is mould two cave in becoming to produce, 2 products of injection moulding simultaneously, therefore this cover die just has 6 rear mold core-pulling mechanisms, the form that the present invention is flicked by employing rear mold B plate 2 realizes loosing core, after injection moulding terminates, just die sinking is started, front mould A plate 1 and rear mold B plate 2 are by mold base shutter 7 snapping, temporarily can not open, open in advance so rear mold B plate 2 and rear mold support fixed head 3, open one end distance afterwards, rear mold supports fixed head 3 and drives shovel base 6, shovel base 6 has oblique T-shaped dovetail groove 8 can play the effect of conversion direction, just slide block 5 can be released from rear core rod 4 by the shovel base 6 being provided with T-shaped dovetail groove 8, thus realize exiting mould product 12 mouth of pipe back-off, this is first time die sinking, wherein the order of die sinking campaign and distance are by sear mechanism 9, inductive pick-up 10 and contour spacing spacing screw control, and square lead 11 play the guiding role.After first time die sinking is all extracted out, injection machine drives rear mold part to continue die sinking, and at this moment mold base shutter 7 is opened, and then front mould A plate 1 and rear mold B plate 2 just can be opened; During matched moulds, due to the effect of sear mechanism 9, front mould A plate 1 and the first matched moulds of rear mold B plate 2, then sear mechanism 9 extrudes stressed, and the rocker piece return in sear mechanism 9 inside contracts, and rear mold B plate 2 and rear mold support fixed head 3 matched moulds again.Mold base shutter 7 of the present invention has good intensity and reliability, extend service life, sear mechanism 9 is safe and reliable, wherein square lead 11 both sides are provided with gib block, gib block material is that bronze adds graphite, and the material of square lead 11 is extraordinary 2510 heat treatment materials of anti-wear performance.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and distortion, these improve and distortion also should be considered as protection scope of the present invention.
