The specific embodiment
Below in conjunction with specific embodiment, the utility model is described in further detail.Should be understood that following examples only are used to the utility model is described but not are used to limit scope of the present utility model.
Fig. 2 is the structural representation of the double-colored rotation injection mold of the utility model section, the structural representation the when structural representation when Fig. 3 is the double-colored rotation injection mold of the utility model matched moulds, Fig. 4 are the die sinking of the double-colored rotation injection mold of the utility model.Double-colored rotation injection mold of the present utility model comprises dynamic model 110 and is fixed in cover half 112 on the top clamping plate 111, described cover half 112 is provided with an inner chamber 113, a pair of slide block 114 is set in described inner chamber 113, be respectively arranged with the groove 115 of symmetry in the bottom of the outer surface of described a pair of slide block 114, described groove 115 is positioned at the intersection of slide block 114 bottom surfaces and slide block 114 vertical planes, groove 115 on the described a pair of slide block 114 constitutes a T font cavity 116 under the matched moulds state, the correspondence position on described dynamic model 110 is provided with a drag hook 117 that cooperates with described T font cavity 116.
Preferably, described drag hook 117 is fixed on the dynamic model 110 by screw thread that is arranged on the drag hook body interior and the bolt cooperation that is arranged on the dynamic model 110.
Preferably, be provided with the Angle Pin 118 that runs through in the described slide block 114, an end of described Angle Pin 118 pass cover half 112 inner chamber 113 the bottom and be fixed on the top clamping plate 111.
Preferably, be arranged with a spring 119 on the described Angle Pin 118, the inside of described slide block 114 is provided with the chamber 120 that cooperates with spring 119 along corresponding Angle Pin 118, be provided with a stop bit mechanism 121 in the bottom of chamber 120, one end of described spring 119 links to each other with stop bit mechanism 121, and the other end is fixed on the bottom of inner chamber 113 of cover half 112.
Preferably, also be provided with the slider guide spare 122 that cooperates with slide block 114 on the sidewall of the inner chamber 113 of described cover half 112, described slide block 114 can slide along the slider guide spare that matches 122.
The course of work of double-colored rotation injection mold of the present utility model is as follows: under the die opening state, a pair of slide block 114 is ejected cover half 112 respectively under the effect of spring 119.During compacted products, dynamic model 110 can move to cover half 112, along with the distance between dynamic model 110 and the cover half 112 is dwindled gradually, the drag hook 117 that is arranged on the dynamic model 110 can move between two slide blocks 114, dynamic model 110 continues to move until contacting with two slide blocks 114 afterwards, along with dynamic model 110 continues to move to cover half 112, two slide blocks 114 slide to cover half 112 along slider guide spare 122, simultaneously, under the effect of Angle Pin 118, distance between two slide blocks 114 is dwindled gradually, the spring 119 that is arranged in two slide blocks 114 also is compressed gradually, finally after dynamic model 110 and cover half 112 are fitted fully, the T font cavity 116 that the groove 115 of two slide blocks, 114 outer surfaces bottom is formed holds the drag hook on the dynamic model 110 117 just, being arranged on spring 119 in two slide blocks 114 this moment also is compressed in the chamber 120 in two slide blocks 114 fully, afterwards injection machine can be in the mold cavity of two slide blocks, 114 inside injected plastic, die sinking after injection moulding is finished, dynamic model 110 is away from cover half 112, spring 119 meetings this moment produce elastic force and act on two slide blocks 114, slide block 114 is promoted to the direction away from cover half 112, simultaneously, the drag hook 117 that is provided with on the dynamic model 110 can drive two slide blocks 114 away from cover half 112, under the effect of Angle Pin 118, spacing between two slide blocks 114 can become big gradually, when dynamic model 110 arrives certain distance away from cover half 112, drag hook 117 just can be fully from 114 disengagings of two slide blocks, two slide blocks 114 finally are drawn out cover half 112 under the effect of spring 119 and drag hook 117, last spring 119 makes two slide blocks 114 static respectively by stop bit mechanism 121, has so far finished the die sinking process.As seen, the drag hook 117 that is provided with in the utility model mould can be pulled out slide block 114 by force from cover half 112, the technical problem of thoroughly having avoided causing slide block 114 not slide into owing to spring 119 elastic force are not enough and requiring the position to influence die sinking.
In sum, mould of the present utility model can be pulled out a pair of slide block by force by drag hook when die sinking from cover half, has thoroughly avoided causing slide block can not slide into the technical problem that requires the position owing to spring force is not enough.
