Abstract
The utility model provides an injection mould bringing convenience to popping of a popping device. The injection mould comprises an upper template, a cushion plate arranged on the upper portion of the upper template and fixed with the upper template, a cushion block and the popping device. The cushion block is arranged between the upper template and the cushion plate and embedded into the cushion plate. One side of the upper template, close to the cushion block, is provided with a gating channel. One side of the cushion block, opposite to the gating channel, is provided with a lower popping device containing groove for the popping device to be contained. The cushion plate is provided with an upper popping device containing groove communicated with the lower popping device containing groove. One side of the popping device, close to the bottom face of the upper popping device containing groove, is provided with a groove. A spring is arranged in the groove. Two ends of the spring respectively contact with the bottom of the upper popping device containing groove and the bottom of the groove. The spring is in a state of compression. One side of the cushion block, close to the upper template, is provided with a receding groove to form a step hole. The injection mould has the advantages of preventing the groove mouth of the popping device containing groove from generating protruding or dent due to the fact that the receding groove is arranged at the groove mouth of the popping device containing groove, and ensuring that the popping device can move smoothly for a long time.
Description
Technical field
The utility model relates to mechanical field, refers to especially a kind of injection mold that ejector ejects that is easy to.
Background technology
During existing injection mold applies to produce widely, all exist in process of production stub bar is cleaned out this link of mould, injection mold is provided with and draws the material nail in the prior art, and draw the material nail to be the barb setting, be difficult to clear up stub bar, be provided with the ejector storage tank in order to clear up on stub bar this part link template, be provided with ejector in this storage tank, be arranged at the top of runner, but in the process that ejector ejects, exist stub bar not come off, stub bar will push ejector storage tank notch when matched moulds, very easily cause ejector storage tank notch to produce projection or depression, ejector storage tank notch place is more coarse, affects the normal operation of ejector.
The utility model content
For the deficiency that prior art exists, the purpose of this utility model is to provide a kind of ejector activity to be easy to smoothly the injection mold that ejector ejects.
The technical solution of the utility model is achieved in that a kind of injection mold that ejector ejects that is easy to, comprise cope match-plate pattern, be positioned at cope match-plate pattern top and with its fixing backing plate, cushion block and cylindrical ejector, described cushion block is between cope match-plate pattern and backing plate and embed the backing plate setting, described cope match-plate pattern is provided with the runner that waters of semicircular in shape shape near a side of cushion block, the side that described cushion block waters runner relatively is provided with for the accommodating lower ejector storage tank of ejector, described backing plate is provided with the upper ejector storage tank that communicates with lower ejector storage tank, consist of the ejector storage tank, the diameter of described ejector bottom surface is greater than the diameter that waters runner, described ejector is provided with groove near a side of upper ejector storage tank bottom surface, be provided with spring in this groove, the two ends of this spring contact with the bottom surface of groove with upper ejector storage tank bottom surface respectively, and spring is in compressive state, it is characterized in that: described cushion block is provided with avoiding hollow groove near a side of cope match-plate pattern, the edge of this avoiding hollow groove notch is positioned at the outside of lower ejector storage tank notch edges, consists of stepped hole.
By adopting technique scheme, notch place at the ejector storage tank is provided with avoiding hollow groove, when preventing that ejector from ejecting, in the situation that stub bar does not come off, extruding ejector storage tank notch, avoided ejector storage tank notch to produce projection or depression, guaranteed that ejector is movable smooth and easy for a long time.
The utility model further is set to: the described avoiding hollow groove degree of depth is 0.5 centimetre, and wherein, described avoiding hollow groove is circular port.
By adopting technique scheme, features simple structure be easy to processing, and the degree of depth of avoiding hollow groove is less, has reduced the wastage of raw material.
Description of drawings
In order to be illustrated more clearly in the utility model embodiment or technical scheme of the prior art, the below will do to introduce simply to the accompanying drawing of required use in embodiment or the description of the Prior Art, apparently, accompanying drawing in the following describes only is embodiment more of the present utility model, for those of ordinary skills, under the prerequisite of not paying creative work, can also obtain according to these accompanying drawings other accompanying drawing.
Fig. 1 is the utility model specific embodiment structural representation;
Fig. 2 is the utility model specific embodiment structure ejector storage tank schematic diagram;
Fig. 3 is ejector and the external diameter structural representation that waters runner.
The specific embodiment
Below in conjunction with the accompanying drawing among the utility model embodiment, the technical scheme among the utility model embodiment is clearly and completely described, obviously, described embodiment only is the utility model part embodiment, rather than whole embodiment.Based on the embodiment in the utility model, those of ordinary skills are not making the every other embodiment that obtains under the creative work prerequisite, all belong to the scope of the utility model protection.
As shown in Figure 1-Figure 3, the utility model discloses a kind of injection mold that ejector ejects that is easy to, comprise cope match-plate pattern 4, be positioned at cope match-plate pattern 4 tops and with its fixing backing plate 2, cushion block 3 and cylindrical ejector 6, described cushion block 3 is between cope match-plate pattern 4 and backing plate 2 and embed backing plate 2 and arrange, described cope match-plate pattern 4 waters runner 8 near what a side of cushion blocks 3 was provided with the semicircular in shape shape, the side that described cushion block 3 waters runner 8 relatively is provided with for the accommodating lower ejector storage tank 10 of ejector, described backing plate 2 is provided with the upper ejector storage tank 9 that communicates with lower ejector storage tank 10, consist of the ejector storage tank, and the outer wall end that ejector 6 is positioned at ejector storage tank 9 is provided with boss 61, cooperate with cushion block 3 and to play position-limiting action, prevent that ejector breaks away from the ejector storage tank in the course of the work, the diameter of described ejector 6 bottom surfaces is greater than the diameter that waters runner 8, described ejector 6 is provided with groove near a side of upper ejector storage tank 9 bottom surfaces, be provided with spring 5 in this groove, the two ends of this spring 5 contact with the bottom surface of groove with upper ejector storage tank 9 bottom surfaces respectively, and spring is in compressive state, in the utility model specific embodiment, described cushion block 3 is provided with avoiding hollow groove 7 near a side of cope match-plate pattern 4, the edge of these avoiding hollow groove 7 notches is positioned at the outside of lower ejector storage tank 10 notch edges, consists of stepped hole; Notch place at the ejector storage tank is provided with avoiding hollow groove 7, when preventing that ejector from ejecting, in the situation that stub bar does not come off, extruding ejector storage tank notch, avoided ejector storage tank notch to produce projection or depression, guaranteed that ejector is movable smooth and easy for a long time.
