Abstract
The utility model discloses an injection mould with a slide block backhoe de-molding structure. A fixed mould core is arranged at the lower end of a fixed molding board; a movable mould core is arranged at the upper end of a de-molding board; the fixed mould core and the movable mould are attached to each other on a mould joint of the fixed molding board and the de-molding board; the slide block backhoe de-molding structure comprises a slide block backhoe which penetrates through the de-molding board and then is fixedly connected with a movable molding board; the upper end of the slide block backhoe penetrates through the movable mould core and then contacts the bottom of a product in the fixed mould core; a slide block limiting block is fixed in the de-molding board and is connected with a slide block base by a slide block spring; a slide block body is arranged on the slide block base; and when the slide block spring is in a compressed state, the slide block body extends into the movable mould core and tightly contacts the upper end of the slide block backhoe. The injection mould with the slide block backhoe de-molding structure disclosed by the utility model is simple in structure; with the slide block backhoe de-molding structure in the mould and by virtue of the combination of molding board movement generated when a conventional mould is opened and the action of the slide block spring, an inverted buckled part inside the product can be smoothly de-molded, and therefore, a phenomenon that the inverted buckled part of the product cannot be ejected is effectively avoided.
Description
Technical field
The utility model relates to die apparatus field, and especially one is applicable to interiors of products back-off, but die location is not enough to make the injection mold with slide block backhoe demolding structure using in oblique top or the situation of oblique top manufacture difficulty when large.
Background technology
In plastic mould, often can encounter interiors of products has some casing series products of back-off: as sphygmomanometer back cover, and toy back cover etc.This series products must be equipped with battery provides the source of power, and therefore the back cover of this series products often can be divided into two parts, and a part is the major part at mould dynamic model: as wiring board etc.Another part is the power resources part at mould slide block: as battery etc.Therefore to there is back-off to block battery part at the Slipper of mould, as shown in Figure 1.And the position of mould is not enough to make in oblique top or the situation of oblique top manufacture difficulty when large in some cases, often can produce the phenomenon that product back-off portion cannot deviate from, and is difficult to get a desired effect and make this type of product utilization prior art.
Summary of the invention
The purpose of this utility model is to provide a kind of injection mold with slide block backhoe demolding structure simple in structure, that effectively avoid product back-off portion to deviate from.
The utility model solves the technical scheme that prior art problem adopts: a kind of injection mold with slide block backhoe demolding structure, comprise solid plate, moving platen and the stripper plate between solid plate and moving platen, the lower end of solid plate is provided with fixed mold core, the upper end of described stripper plate is provided with mavable module core, and fixed mold core and mavable module core are bonded to each other at the die joint place of solid plate and stripper plate; Between described stripper plate and moving platen, be provided with spring; Described slide block backhoe demolding structure comprises the slide block backhoe being fixedly connected with moving platen through described stripper plate, touch through the product bottom connection in mavable module core and fixed mold core the upper end of slide block backhoe, in described stripper plate, be fixed with slide block limited block, slide block limited block is connected with take-up housing by sliding block spring, take-up housing is provided with slide block body, and make when sliding block spring during in compressive state slide block body stretch in mavable module core and with the upper end close contact of described slide block backhoe.
Between described solid plate and stripper plate, be provided with damping pin.
The beneficial effects of the utility model are: the utility model is simple in structure, template motion when it utilizes conventional mould die sinking by slide block backhoe demolding structure is set in mould, coordinate the effect of sliding block spring to make the back-off demoulding smoothly of interiors of products, thus the phenomenon of effectively having avoided product back-off portion to deviate from.

Detailed description of the invention
Below in conjunction with the drawings and the specific embodiments, the utility model is described:
Fig. 4-5 are respectively the utility model mould structure schematic diagram and side view.As shown in the figure, a kind of injection mold with slide block backhoe demolding structure, comprise solid plate 13, moving platen 10 and the stripper plate 12 between solid plate 13 and moving platen 10, the upper end that the lower end of solid plate 13 is provided with fixed mold core 7, stripper plate 12 is provided with mavable module core 2, and fixed mold core 7 is bonded to each other with the die joint place of stripper plate 12 at solid plate 13 with mavable module core 2; Between stripper plate 12 and moving platen 10, be provided with spring 11; Between solid plate 13 and stripper plate 12, be provided with damping pin 14.
Fig. 2-3 show in detail the concrete structure of slide block backhoe demolding structure.Slide block backhoe demolding structure comprises the slide block backhoe 1 being fixedly connected with moving platen 10 through stripper plate 12, touch through the bottom connection of the product 9 in mavable module core 2 and fixed mold core 7 upper end of slide block backhoe 1, in stripper plate 12, be fixed with slide block limited block 3 by screw 4, slide block limited block 3 is connected with take-up housing 5 by sliding block spring 6, take-up housing 5 is provided with slide block body 8, and make when sliding block spring 6 during in compressive state slide block body 8 stretch in mavable module core 2 and with the upper end close contact of slide block backhoe 1.
Operating principle of the present utility model is:
Pull the base plate of moving platen 10 that solid plate 13, moving platen 10 are moved by forming machine, again because the effect of the damping pin 14 between solid plate 13 and stripper plate 12, solid plate 13 and stripper plate 12 temporarily can not be separated, and spring 11 is easy to separately stripper plate 12 and moving platen 10, so in the time that forming machine die sinking is moved, stripper plate 12 and moving platen 10 can first separate.
When stripper plate 12 and moving platen 10 is separately time, moving platen 10 is with movable slider backhoe 1 to move simultaneously, like this will be gapped between slide block body 8 and mavable module core 2, and sliding block spring 6 acts on slide block limited block 3 to 5 one power towards mavable module core 2 inside of take-up housing, like this when stripper plate 12 and moving platen 10 is separately time, take-up housing 5 with movable slider body 2 just to the internal motion of mavable module core 2, thereby slide block body 8 and the inner back-off of product 9 are separated.Thereby ejecting product, makes product 9 separate with mould smoothly.
Above content is in conjunction with concrete optimal technical scheme further detailed description of the utility model, can not assert that concrete enforcement of the present utility model is confined to these explanations.For the utility model person of an ordinary skill in the technical field, without departing from the concept of the premise utility, can also make some simple deduction or replace, all should be considered as belonging to protection domain of the present utility model.
