[specific embodiment]

As Fig. 1-double-colored directive wheel shown in Fig. 10 is molded composable mold, including rear pattern plate 1 and the cooperation injection molding of rear pattern plate 1 Form the first chromatograph of directive wheel the first front template 2 and with rear pattern plate 1 cooperate the second chromatograph of injection molding directive wheel second Front template 3, first front template 2 are equipped with the first mode 21, are equipped in first mode 21 and are oriented to for injection molding The first type chamber 22 of the first chromatograph is taken turns, second front template 3 is equipped with the second mode 31, is equipped with and uses in second mode 31 In the second type chamber 32 of the second chromatograph of injection molding directive wheel, the rear pattern plate 1, which is equipped with successively to insert, protrudes into 22 He of the first type chamber The rear mold mold insert 11 of the first chromatograph of injection molding directive wheel and the second chromatograph is respectively cooperating in second type chamber 32, and in the first color The first chromatograph is fixed on the rear mold mold insert 11 and inserts with rear mold mold insert 11 and protrudes into second type chamber 32 after layer injection molding. After rear pattern plate and the first front template cooperation the first chromatograph of injection molding directive wheel, by the way that the first chromatograph is fixed on rear mold mold insert On, so that the first chromatograph is inserted with rear mold mold insert and protrude into the second front template the injection molding operation for carrying out the second chromatograph, to make A set of rear mold can be shared by obtaining the first front template and the second front template, carry out double-shot moulding works without two sets of complete molds Industry can then effectively improve during injection molding without being removed from the molds and being carried on another mold by moulding It is molded production efficiency, production production capacity is greatly improved, improves the market competitiveness of enterprise.

The rear mold mold insert 11 is equipped with can be along the first front template 2 and rear pattern plate 1 and the second front template 3 and rear pattern plate 1 The rear mold mold insert forming ends 111 protruded into the first type chamber 22 and second type chamber 32 are inserted in molding direction respectively, in order to complete first The first chromatograph can be made to be stably fixed on rear mold mold insert after chromatograph injection molding operation, the rear mold mold insert forming ends 111 are along molding Direction is convexly equipped with positioning convex platform 112 and the convex being located on outside the positioning convex platform 112 along 113, and the convex is along 113 Being formed between the positioning convex platform 112, which is fixed on the first chromatograph on rear mold mold insert 11, is positioned to type groove 114.Complete first After chromatograph injection molding operation, what the first chromatograph moulding can be stable, which be placed on, is positioned in type groove 114.

Specifically, being opened for the ease of the first mode 21 and the second mode 31, first mode 21 includes two energy edges The the first mode monomer 211 for closing up in opposite directions or being relatively distant from perpendicular to the direction of open mold, second mode 31 include two Can be along direction the second mode monomer 311 that close up in opposite directions or be relatively distant from perpendicular to open mold, first front template 2 and the The mode connector 4 being fixedly connected with the first mode monomer 211 and the second mode monomer 311, and are equipped on two front templates 3 Band mavable module core connector 4 is along perpendicular to opening while one front template 2 is detached from rear pattern plate 1 along die sinking direction with mavable module core connector 4 The direction of molding keeps two corresponding first mode monomers 211 relatively remote far from another corresponding mode connector 4 From band mavable module core connector 4 is along vertical while the second front template 3 is detached from rear pattern plate 1 along die sinking direction with mavable module core connector 4 Make two corresponding second mode monomers 311 opposite far from another corresponding mode connector in the direction of open mold It is separate.By the first front template and the second front template after the decoupling mould when the first mode of synchronous drive and the second mode are opened respectively Mould realizes mold die sinking synchronous with mode, die sinking program is simplified, to further increase whole injection molding production efficiency.

In order to realize the first front template and the second front template after the decoupling mould when the corresponding mode connection of difference synchronous drive Part 4 is mobile to drive the first mode and the second mode open mold, and the mode connector 4 can be opposite on the first front template 2 First front template 2 is moved along perpendicular to open mold direction, and the mode connector 4 is on the second front template 3 before energy opposite second Template 3 is moved along perpendicular to open mold direction, and the rear pattern plate 1 is equipped with the wedge block being flexibly connected with mode connector 4 12, the wedge block 12 is equipped with sliding bevel 121 far from one end of rear pattern plate 1 along molding direction, on the sliding bevel 121 Equipped with the sliding ramp 122 extended along open mold direction, and the distance between two sliding ramps 122 being oppositely arranged are along die sinking side To being gradually increased, the mode connector 4 is equipped with the sliding groove 41 being slidably matched with sliding ramp 122, mould before described first When plate 2 is detached from rear pattern plate 1 along die sinking direction with mavable module core connector 4 mode connector 4 along the oblique sliding of sliding ramp 122 from And it is two corresponding to make mode connector 4 then far from another corresponding mode connector 4 along the direction perpendicular to open mold The first mode monomer 211 be relatively distant from along perpendicular to open mold direction, second front template 3 is with 4 edge of mavable module core connector Mode connector 4 is along the oblique sliding of sliding ramp 122 to make mode connector 4 along vertical when die sinking direction is detached from rear pattern plate 1 Then make two corresponding second mode monomers 311 along vertical far from another corresponding mode connector 4 in the direction of open mold Directly it is relatively distant from open mold direction.

In order to further cooperate the double-shot moulding operation of directive wheel, the mould before first is additionally provided on first front template 2 Mould mold insert 24 before the molding direction of plate 2 and rear pattern plate 1 inserts protrude into cooperation the first chromatograph of injection molding in the first type chamber 22 first, It is additionally provided with to insert to protrude into second type chamber 32 along the molding direction of the second front template 3 and rear pattern plate 1 on second front template 3 and cooperate Mould mold insert 34 before the second of the second chromatograph of injection molding.

For the ease of being poured molten plastic in the first type chamber 22 and second type chamber 32, set on mould mold insert 24 before described first There is the first mold insert communicated with the first type chamber 22 to be poured channel 241, first front template 2 is equipped with and the first mold insert Casting channel 241 communicate first before mould casting channel 25, mould mold insert 34 is equipped with and the second type chamber 32 before described second The the second mold insert casting channel 341 communicated, second front template 3 are equipped with the communicated with the second mold insert casting channel 341 Mould is poured channel 35 before two.

In order to be molded the double-colored directive wheel of production in batch, production production capacity is improved, the mode connection on the first front template 2 Part 4 is connected with the first mode of multiple groups 21, and the mode connector 4 on the second front template 3 is connected with the second mode of multiple groups 31.

The present embodiment working principle is as follows:
