The high-performance double-ejection mold structure comprises a panel, a front mold plate, a rear mold plate, an ejector pin panel, an ejector pin bottom plate, a bottom plate, an ejection rod, an insert pin, a spring, an ejector pin, a front mold core and a rear mold core, wherein the insert pin is arranged on the bottom plate; the ejection rod is arranged on the ejector pin bottom plate; the spring is arranged in the ejection rod and is positioned and guided by the insert pin; the ejection rod penetrates through the ejector pin panel and the ejector pin bottom plate; the ejector pin panel, the ejector pin bottom plate and the ejection rod are positioned and installed; the ejector pin bottom plate is positioned at the lower end of the ejector pin panel; the panel is arranged at the upper end of the front mold plate; the front mold core is arranged in the front mold plate; the rear mold core is arranged in the rear mold plate. According to the high-performance double-ejection mold structure, a simple and effective double-ejection mold stripping mode is provided, a standard mold frame does not need to an extra ejector pin plate, the manufacturing cost of a non-standard mold frame is eliminated, the mold structure is simplified, the cost is saved, and the working efficiency is improved.
Description
Technical field
The utility model belongs to mould applications, relates in particular to and in product rear mold, has border barb normally depanning and a kind of high-performance secondary ejection mold structure of taking.
Background technology
In tradition plastic rear mold, there is border barb; a demoulding, eject after action, plastic back-off wraps on rear model cavity and is difficult to depanning, must increase a demoulding again and eject action; just can make plastic forced stripper mechanism; to guarantee plastic part quality, this class mould emptier is called secondary ejecting mechanism, and traditional secondary ejection structure is generally that design 3-4 piece ejector retainner plate divides and ejects for 2 times; cause the complicated of mould structure change; the cycle stretch-out that injection moulding is produced, has wasted cost, affects production efficiency.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of simple and effective Double-ejection depanning mode, standard die set does not need to increase in addition ejector retainner plate, wall has exempted to do the expense that nonstandard mould bases increases, simplified mould structure, save cost, increased the secondary ejection mold structure of operating efficiency.
The utility model is achieved through the following technical solutions: a kind of high-performance secondary ejection mold structure, comprise panel, front template, rear pattern plate, thimble panel, Ejector Retainer Plate, base plate, knock-pin, pin, spring, thimble, front cavity and rear cavity, described pin is arranged on base plate, described knock-pin is arranged on described Ejector Retainer Plate, described spring is arranged in knock-pin, described spring is by pin location and guiding, described Ejector Retainer Plate is positioned at thimble panel lower end, described panel is arranged on front template upper end, described front cavity is arranged in front template, described rear cavity is arranged in rear pattern plate.
As preferred technical scheme, described knock-pin is through thimble panel and Ejector Retainer Plate.
As preferred technical scheme, location and installation between described thimble panel, Ejector Retainer Plate and knock-pin.
As preferred technical scheme, between described front cavity and rear cavity, be provided with a cavity, in cavity, lay product.
As preferred technical scheme, described product is provided with inserted link, and described inserted link is arranged in the pin of knock-pin.
The beneficial effects of the utility model are: the utility model provides a kind of simple and effective Double-ejection depanning mode, standard die set does not need to increase in addition ejector retainner plate, and wall has exempted to do the expense that nonstandard mould bases increases, and has simplified mould structure, save cost, increased operating efficiency.
Accompanying drawing explanation
For ease of explanation, the utility model is described in detail by following specific embodiment and accompanying drawing.
Fig. 1 is the structural representation before the utility model ejects;
Fig. 2 is the structural representation after the utility model ejects.
The specific embodiment
As depicted in figs. 1 and 2, a kind of high-performance secondary ejection mold structure of the present utility model, comprise panel 1, front template 2, rear pattern plate 3, thimble panel 4, Ejector Retainer Plate 5, base plate 6, knock-pin 10, pin 11, spring 12, thimble 13, front cavity 20 and rear cavity 21, described pin 11 is arranged on base plate 6, described knock-pin 10 is arranged on described Ejector Retainer Plate 5, described spring 12 is arranged in knock-pin 10, described spring 12 is by pin 11 location and guiding, described Ejector Retainer Plate 5 is positioned at thimble panel 4 lower ends, described panel 1 is arranged on front template 2 upper ends, described front cavity 20 is arranged in front template 2, described rear cavity 21 is arranged in rear pattern plate 3.
As preferred embodiment, knock-pin 10 is through thimble panel 4 and Ejector Retainer Plate 5.
In the present embodiment, thimble panel 4, Ejector Retainer Plate 5 and 10 location and installation of knock-pin.
Wherein, between front cavity 20 and rear cavity 21, be provided with a cavity, lay product 100 in cavity, product 100 is provided with inserted link, and described inserted link is arranged in the pin 11 of knock-pin 10.
During die sinking under the effect of injection machine push rod, thimble panel 4 and Ejector Retainer Plate 5 move toward cover half direction, under the effect of Compress Spring 12, it is rear motionless that knock-pin 10 moves L distance toward cover half direction, because pin 11 is fixed, when product 100 glue positions have gone out pin 11, continue to eject, under the effect of thimble 13, product is out of shape inward, thereby deviates from back-off, during matched moulds, under the effect of Ejector Retainer Plate 5 toward rear mold direction bear down on one rod 10 cup head, thereby realize safe matched moulds, product can be realized fully-automatic production.
The beneficial effects of the utility model are: the utility model provides a kind of simple and effective Double-ejection depanning mode, standard die set does not need to increase in addition ejector retainner plate, and wall has exempted to do the expense that nonstandard mould bases increases, and has simplified mould structure, save cost, increased operating efficiency.
The above, be only the specific embodiment of the present utility model, but protection domain of the present utility model is not limited to this, and any variation of expecting without creative work or replacement, within all should being encompassed in protection domain of the present utility model.Therefore, protection domain of the present utility model should be as the criterion with the protection domain that claims were limited.
