Abstract
The invention discloses a two-color plastic product forming mold device. The mold device at least comprises a male mold, a first female mold, a second female mold and a machine platform, wherein a movable insert and a driving lever are arranged in the male mold; the movable insert is connected with the driving lever via an elastic element; the lateral surface of the movable insert opposite to thedriving lever is provided with a groove with a certain inclination; a convex part is arranged at a corresponding position on the driving lever; the driving lever is also provided with a perforation with a certain inclination; a lateral surface of the first female mold opposite to the male mold is provided with a lug and a deflector rod; and a bayonet lock is arranged on the deflector rod corresponding to the perforation; the lateral surface of the second female mold opposite to the male mold is a horizontal plane; a sprue is arranged on the inner side of the second female mold; and the machineplatform is connected with the first female mold and the second female mold in a horizontal manner. The mold device of the invention has the advantage that the structure is simple, and completes processing two-color three-dimensional tags by matching with the different positions of the movable insert.
Description
Technical field
The present invention relates to a kind of plastic cement of one injection molding, relate in particular to a kind of die device of plastic article dual-color forming.
Background technology
In commodity market, businessman is different from other like products for the product that makes oneself, need stick sign, trade mark or the unique ornaments of oneself on product.Usually these signs, trade mark or ornaments adopt mode of printing directly to be formed at the surface of product more.Adopt mode of printing technology simple, be confined to planar design, can't be shaped to three-dimensional sign but the shortcoming of its existence is exactly a mark printed.Be directed to this, people design the label of concrete stereoeffect, and this label adopts plastic material usually, utilize mould heat pressure, injection moulding to form.But present employed 3-D signboard owing to adopt one-time formed mode more, and label can't mold complicated moulding, and also can't form various color; Even can produce double-colored 3-D signboard, but because the zone of forming stereo sign does not link to each other, a plurality of cast gates need be set in processing mold can machine-shaping.
Summary of the invention
Technical scheme to be solved by this invention is exactly at present making product nameplate, the existing deficiency of ornaments, provides a kind of need that the die device that a cast gate can be processed diversified moulding, possess two kinds of double-colored 3-D signboards of color is set in mould.
For solving the problems of the technologies described above, the present invention has adopted following technical scheme: this die device comprises at least: male model, its inside is provided with movably goes into son and drive link, described movably go into the son with described drive link between be connected by elastic parts, wherein, describedly movably go into son and be provided with the groove with constant slope in the face of the side of described drive link, described drive link corresponding position is provided with protruding falcon, and also is provided with the perforation with constant slope on the described drive link; First master mold, its side in the face of described male model is provided with projection, and is provided with driving lever, and corresponding described perforation place of this driving lever is provided with bayonet lock; Second master mold, its side in the face of described male model is a horizontal plane, this second master mold inboard is provided with cast gate; And board, level connects described first master mold and second master mold.
More excellent, the bottom of described male model also is provided with at least one short slot, is provided with setting element in the base corresponding position of this die device.
More excellent, described setting element comprises: positioning ball; And elastic parts, be connected the groove inner bottom part of described positioning ball and described base.
More excellent, described elastic parts is a spring.
Compared with prior art, the present invention has the following advantages:
1, when first time moulding, adopt structures such as driving lever and drive link, driving lever is pushed into drive link and movably goes into son and tightly engage, and makes that movably going into sub upper surface projects in the cavity of converted products, thereby finishes the plastic parts of first kind of color earlier;
2, when second time moulding, under the impetus of spring, drive link is pushed into and movably goes into subsolution and remove fastening state, make and movably go into the cavity place that sub upper surface is recessed converted products, make second kind of color plastic rubber shaping place form a cavity that is interconnected, thereby only need a cast gate can finish the pouring operation of second kind of color plastic cement.
The present invention is simple in structure, utilizes the difference of movably going into sub position to finish the processing of the double-colored 3-D signboard that possesses two kinds of colors with cooperation.
Description of drawings
Cross-sectional view when Fig. 1 is a preferred embodiment of the present invention moulding for the first time.
Cross-sectional view when Fig. 2 is a preferred embodiment of the present invention moulding for the second time.
The specific embodiment
For describing technology contents of the present invention, structural feature in detail, illustrated in detail below in conjunction with embodiment and conjunction with figs..
Please consult Fig. 1 and Fig. 2 simultaneously, be the cross-sectional view of a preferred embodiment of the present invention.This die device comprises: male model 12, its inside is provided with movably goes into son 121 and drive link 122, described movably go into the son 121 with described drive link 122 between be connected by spring 123, wherein, describedly movably go into son 121 and be provided with groove 1211 with constant slope in the face of the sides of described drive link 122, described drive link 122 corresponding positions are provided with protruding falcon 1221, also be provided with perforation 1222 on the described drive link 122, and also be provided with two short slots 124 in the bottom of described male model 12 with constant slope; First master mold 111, its side in the face of described male model 12 is provided with projection 1111, and is provided with driving lever 1112, and these driving lever 1112 corresponding described perforation 1222 places are provided with bayonet lock 1113; Second master mold 112, its side in the face of described male model 12 is a horizontal plane, this second master mold inboard is provided with cast gate 1121; Board (figure does not show), level connects described first master mold 111 and second master mold 112; And base 13,124 places are provided with setting element 131 in described base 13 corresponding described short slots, and this setting element 131 comprises: positioning ball 1312; And spring 1311, be connected the bottom in the groove 132 of described positioning ball 1312 and described base 13.
When first time moulding, described driving lever 1112 is pushed into described drive link 122 with described movably to go into son 121 and tightly engage, makes describedly movably to go into sub 121 upper surface and project in the cavity 21 of converted products, thereby finishes the plastic parts of first kind of color earlier;
When second time moulding, under the impetus of described spring 123, described drive link 122 is pushed into described movably goes into sub 121 engagement release states, make described cavity 21 places that son 121 upper surface is recessed converted products of movably going into, make second kind of color plastic rubber shaping place form a cavity that is interconnected 22, thereby only need described second master mold, 112 interior cast gates 1121 that are provided with to finish the pouring operation of second kind of color plastic cement.
The above is preferred embodiment of the present invention only, is not to be used for limiting practical range of the present invention; Every according to equivalence variation and modification that the present invention did, all covered by claim of the present invention.
