Description
Technical field
The utility model relates to the mould mechanical field, is specifically related to the leading ejecting mechanism of a kind of plastic mould, is used for the demoulding of plastic cement products.
Background technology
In the production of plastic cement products, plastic cement products need to take out it after die for molding from mould, and this process is referred to as the demoulding, and releasing process is mainly by the ejecting mechanism ejection device.At present, the demoulding ejecting mechanism plastic emitting mouth of a river of using needs just can eject through repeatedly pushing up by jack-up, overlong time used in this ejection process repeatedly, the cool time of product is longer, product easily is out of shape, improve defect rate, also caused the waste of plastic material simultaneously, added the production cost of product.
The utility model content
In order to overcome the deficiencies in the prior art, the purpose of this utility model is to provide a kind of plastic mould leading ejecting mechanism, can the demoulding when ejecting the mouth of a river, and two processes are once completed, and simple to operate, the used time is short, and yield rate is high, and product cost is low.
For addressing the above problem, the technical scheme that the utility model adopts is as follows:
The leading ejecting mechanism of a kind of plastic mould comprises die cavity, core, impression bolster and core fixing plate and ejecting mechanism; Wherein die cavity is positioned at the below of impression bolster, and core is positioned at the top of core fixing plate; Be provided with chamber, the mouth of a river in die cavity and impression bolster, the mouth of a river is equipped with in the chamber in the mouth of a river, and the mouth of a river communicates with die cavity; It is inner that described ejecting mechanism is positioned at core and core fixing plate, and it comprises and ejects in advance thimble, Double-ejection thimble, thimble panel, Ejector Retainer Plate and eject drive unit; Described core fixing plate inside is provided with a cavity, and described Ejector Retainer Plate is positioned at cavity, and the thimble panel is positioned on Ejector Retainer Plate, and drive unit connecting ejector pin top board and Ejector Retainer Plate are under the effect of drive unit, up and down in thimble and Ejector Retainer Plate cavity; Described eject in advance the thimble upper end be connected in the mouth of a river under, its lower end is fixed on the thimble panel; Described Double-ejection thimble upper end flushes and communicates with die cavity with the core top, in its below socket one telescopic, described telescopic socket and Ejector Retainer Plate.
As preferred scheme, the utility model can also be realized by following scheme:
In time reset afterwards in order to facilitate ejecting mechanism can realize ejecting, the leading ejecting mechanism of plastic mould described in the utility model also comprises the thimble that resets, and the described thimble upper end of resetting is connected to the lower end of telescopic, and its lower end is free end and stretches out Ejector Retainer Plate.
Compared to existing technology, the beneficial effects of the utility model are: the leading ejecting mechanism of plastic mould described in the utility model can eject the mouth of a river and product at short notice, eject and can not impact product simultaneously, the finished product rate is high, save plastic material, further reduced the cost of product.The leading ejecting mechanism of plastic mould of the present utility model also has simple in structure, easy to operate, low cost and other advantages.
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail.
Description of drawings
Fig. 1 is the state diagram of the leading ejecting mechanism of plastic mould described in the utility model before ejecting;
Fig. 2 is the state diagram of the leading ejecting mechanism of plastic mould described in the utility model in ejection process;
Fig. 3 is the state diagram after the leading ejecting mechanism ejecting product of plastic mould described in the utility model.
The specific embodiment
As Fig. 1, Fig. 2, shown in Figure 3, the leading ejecting mechanism of plastic mould described in the utility model comprises die cavity 21, core 22, impression bolster 1 and core fixing plate 6 and ejecting mechanism; Wherein die cavity 21 is positioned at the below of impression bolster 1, and core 22 is positioned at the top of core fixing plate 6; Be provided with chamber, the mouth of a river in die cavity 21 and impression bolster 1, the mouth of a river 3 is housed in chamber, the mouth of a river, the mouth of a river 3 communicates with die cavity 21; Described ejecting mechanism is positioned at core 22 and core fixing plate 6 inside, and it comprises and ejects in advance thimble 4, Double-ejection thimble 5, thimble panel 7, Ejector Retainer Plate 8 and eject the drive unit (not shown); Described core fixing plate inside is provided with a cavity 10, described Ejector Retainer Plate 8 is positioned at cavity 10, and thimble panel 7 is positioned on Ejector Retainer Plate 8, drive unit connecting ejector pin top board 7 and Ejector Retainer Plate 8, under the effect of drive unit, thimble top board 7 and Ejector Retainer Plate 8 can be interior up and down at cavity 10; Described eject in advance thimble 4 upper ends be connected in the mouth of a river 3 under, its lower end is fixed on thimble panel 7; Described Double-ejection thimble 5 upper ends flush and communicate with die cavity 21 with core 22 tops, in its below socket one telescopic, described telescopic socket and Ejector Retainer Plate 8.
The operation principle of the leading ejecting mechanism of plastic mould described in the utility model is as follows: after injection moulding is completed, die cavity breaks away from core, the mouth of a river also breaks away from from chamber, the mouth of a river, the plastic cement products of injection mo(u)lding is stayed on core, under the effect of drive unit, thimble panel and Ejector Retainer Plate move upward, and eject in advance thimble and move upward the mouth of a river jack-up that makes progress thereby drive simultaneously; The Double-ejection thimble also and then moves upward in the process that thimble panel and Ejector Retainer Plate continue to move upward, and the Double-ejection thimble passes from core under the power of drive unit, thus with the product on core up jack-up realize product stripping.
As preferred scheme, the utility model can also be realized by following scheme:
For facilitate ejecting mechanism can realize ejecting in time reset afterwards, the leading ejecting mechanism of plastic mould described in the utility model, also comprise the thimble 9 that resets, described thimble 9 upper ends of resetting are connected to the lower end of telescopic, and its lower end is free end and stretches out Ejector Retainer Plate 8.
Above-mentioned embodiment is only preferred embodiment of the present utility model; can not limit with this scope of the utility model protection, the variation of any unsubstantiality that those skilled in the art does on basis of the present utility model and replacement all belong to the utility model scope required for protection.
