Abstract
The utility model discloses a plastic mould with a secondary ejection structure, belonging to the technical field of plastic mould processing. The technical key point of the plastic mould lies in that a mould body is provided and is internally provided with a first ejector plate and a first ejector bottom plate; the first ejector plate is provided with a first return pin and a first ejector pin corresponding to a product forming cavity; a second ejector bottom plate and a second ejector plate are arranged above the first ejector plate; a first spring is sheathed at the outer periphery of the first return pin between the first ejector plate and the second ejector bottom plate; the second ejector plate is provided with a second return pin and a second ejector pin corresponding to the product forming cavity; and a second return spring is arranged at the outer periphery of the second return pin between the second ejector plate and the mould body. The plastic mould is simple in structure and uniform in ejection force and is used for processing plastic products.
Description
Technical field
The utility model relates to a kind of plastic mould, more particularly, relates in particular to a kind of plastic mould with secondary ejecting structure.
Background technology
Because general mould structure is aspect ejecting, all be by top rod jack-up Ejector Retainer Plate and ejector retainner plate, eject product by the thimble on the ejector retainner plate again, but under special circumstances, the shape more complicated of some product or more special, just once eject, can cause the product top not come out, perhaps because the dynamics that ejects is too fast, cause the product distortion, can cause product assembling button bit to break when serious, make product needed repair or cause product rejection, not only increase production cost, and made the qualification rate of product reduce.
The utility model content
The purpose of this utility model is at above-mentioned the deficiencies in the prior art, provide a kind of simple in structure, eject the plastic mould that dynamics has the secondary ejecting structure uniformly.
The technical solution of the utility model is achieved in that a kind of plastic mould with secondary ejecting structure, comprise die ontology, in die ontology, be provided with first ejector retainner plate and first Ejector Retainer Plate, on first ejector retainner plate, be provided with first back stitching and with corresponding first thimble in formed product chamber, wherein said first ejector retainner plate top also is provided with second Ejector Retainer Plate and second ejector retainner plate, and the first back stitching outer race between first ejector retainner plate and second Ejector Retainer Plate is provided with first spring; On second ejector retainner plate, be provided with second back stitching and with corresponding second thimble in formed product chamber, the second back stitching outer race between second ejector retainner plate and die ontology is provided with second return spring.
In the above-mentioned plastic mould, be provided with limited block between described second ejector retainner plate upper surface and the die ontology inwall top with secondary ejecting structure.
After the utility model adopts said structure, by increasing by second Ejector Retainer Plate and second ejector retainner plate, utilize second thimble on second ejector retainner plate to cooperate first thimble on first ejector retainner plate at first product once to be ejected in advance, make between product and the mould to break away from, but do not leave mould fully, then under the continuation of top rod advances, second thimble stops to move under the effect of limited block, and first thimble continues forward impelling, and product is ejected mould fully, finishes the demoulding of product; The mode that adopts secondary to eject, can be when ejecting in advance for the first time, with product and mould separating certain distance, for eject next time, the space is provided, allows next time and eject more smooth and easy, can not occur simultaneously owing to once eject dynamics too suddenly or too fast, cause the product distortion or break the situation of assembling button bit, guarantee the qualification rate of converted products.
Description of drawings
The utility model is described in further detail below in conjunction with the embodiment in the accompanying drawing, but do not constitute any restriction of the present utility model.
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model when once ejecting;
Fig. 3 is the structural representation of the utility model secondary when ejecting.
Among the figure: die ontology 1, first ejector retainner plate 2, the first back stitching 2a, the first thimble 2b, the first return spring 2c, first Ejector Retainer Plate 3, second Ejector Retainer Plate 4, second ejector retainner plate 5, the second back stitching 5a, the second thimble 5b, the second return spring 5c, limited block 6.
The specific embodiment
Consult shown in Figure 1, a kind of plastic mould of the present utility model with secondary ejecting structure, comprise die ontology 1, in die ontology 1, be provided with first ejector retainner plate 2 and first Ejector Retainer Plate 3, on first ejector retainner plate 2, be provided with the first back stitching 2a and with the corresponding first thimble 2b in formed product chamber, also be provided with second Ejector Retainer Plate 4 and second ejector retainner plate 5 above first ejector retainner plate 2, the first back stitching 2a outer race between first ejector retainner plate 2 and second Ejector Retainer Plate 4 is provided with the first spring 2c; On second ejector retainner plate 5, be provided with the second back stitching 5a and with the corresponding second thimble 5b in formed product chamber, the second back stitching 5a outer race between second ejector retainner plate 5 and die ontology 1 is provided with the second return spring 5c; Between second ejector retainner plate, 5 upper surfaces and die ontology 1 inwall top, be provided with limited block 6, be used to prevent that 5 displacements of second ejector retainner plate from too much causing the fretting wear between mould.
Consult Fig. 2, shown in Figure 3, after the product injection moulding is finished, the front and back mould separately, start up jack-up of top rod that external drive makes die ontology 1 bottom, promote first ejector retainner plate 2, first Ejector Retainer Plate 3, second Ejector Retainer Plate 4 and second ejector retainner plate 5 up move simultaneously, product is ejected in advance, when the second thimble 5b on second ejector retainner plate 5 runs into limited block 6, promptly stop to move, eject in advance for the first time and finish, this moment, product was with mold separation but do not break away from mould fully, under the continuation of top rod promoted, first ejector retainner plate 2 and first Ejector Retainer Plate 3 continued up to move, and the first thimble 2b continues up jack-up product, make product break away from die ontology 1 fully, the secondary of finishing product ejects.The mode that adopts secondary to eject, can be when ejecting in advance for the first time, with product and mould separating certain distance, for eject next time, the space is provided, allows next time and eject more smooth and easy, can not occur simultaneously owing to once eject dynamics too suddenly or too fast, cause the product distortion or break the situation of assembling button bit, guarantee the qualification rate of converted products.
