The specific embodiment
For making the object, technical solutions and advantages of the present invention clearer, below in conjunction with drawings and Examples, the present invention is described in further detail.
Refer to shown in Fig. 3 and Fig. 4, injection mold comprises panel 1, flange 3, sprue bushing 4, A plate 5, front cavity 6, regrinding-material 7, rear cavity 8, B plate 9, back stitching 10, thimble panel 11, Ejector Retainer Plate 12, base plate 13, rubbish nail 14 and mouth of a river pin 16, wherein panel 1 is fixedly connected with A plate 5 by screw 2, described front cavity 6 is fixedly connected with A plate 5, B plate 9 is fixedly connected with described rear cavity 8, mouth of a river pin 16 is separately fixed on thimble panel 11 and Ejector Retainer Plate 12, mouth of a river pin 16 is also fixedly connected with thimble 15, on described Ejector Retainer Plate 12, be provided with through hole, thimble 15 is connected with base plate 13 by through hole.
Thimble 15 comprises the first thimble portion 151 and the second thimble portion 152, the first thimble portion 151 is fixedly connected with mouth of a river pin 16, described the second thimble portion 152 is fixed on base plate 13, the diameter of the first thimble portion 151 is greater than the diameter of the second thimble portion 152, through hole comprises the first through hole 121 and the second through hole 122, the radius of described the first through hole 121 equals the diameter of the first thimble portion 151, the radius of the second through hole 122 equals the diameter of described the second thimble portion 151, and the length of the first through hole 121 is greater than the length of the first thimble portion 151.In the present embodiment, the length of the first through hole 121 is greater than 8 millimeters of the first thimble portion 151 length.
Injection mold also comprises that ejector pin 19 one end are parallel with the endoporus of product for working ejector sleeve 18 and the ejector pin 19 of the effect of ejecting, and the other end is fixedly connected with base plate 13.Regrinding-material 7 is connected with product.Further, one end of ejector pin 19 is also fixedly connected with ejector sleeve briquetting 17.Injection mold also comprises holder department 20 and the middle holder limit 21 for playing the guiding role.
Refer to shown in Fig. 5, during die sinking, when product is ejected by thimble, thimble bottom surface under mouth of a river pin 16 also has certain distance (being 8MM) to contact with Ejector Retainer Plate 12 end faces, causing mouth of a river pin 16 cannot follow thimble panel 11 ejects together, thereby mouth of a river pin 16 cannot eject regrinding-material 7, the effect that mouth of a river thimble time delay ejects is played by this mechanism, now ejecting state, regrinding-material 7 remains static product, between regrinding-material 7 and product, produce relative motion, regrinding-material 7 makes product can depart from the mouth of a river with the relative motion of product, then the thimble 15 under mouth of a river pin 16 ejects at the mouth of a river after Ejector Retainer Plate 12 contacts together with product, now product is separated with the mouth of a river.
The present embodiment enters the design of sealing rubber die structure by optimizing common style big water gap, be beneficial to and select product to enter glue, there will not be product and the mouth of a river can not be separated, and need to be equipped with special messenger, carry out post-processed, Qie Ci mechanism is simply convenient to change, and die cost is low, reduces cost of labor, raise the efficiency, be more conducive to produce.
Above content is in conjunction with concrete embodiment further description made for the present invention, can not assert that specific embodiment of the invention is confined to these explanations.For general technical staff of the technical field of the invention, without departing from the inventive concept of the premise, can also make some simple deduction or replace, all should be considered as belonging to protection scope of the present invention.
