The specific embodiment
Shown in Fig. 1-7, a kind of interior tap of injection mold is characterized in that comprising fuse 1, the described fuse 1 outer rotating inner pulling mechanism that is provided with.
As the further optimization to technique scheme, described rotating inner pulling mechanism comprises the annular base 6 that is socketed and is fixed on the described fuse 1, is shaped with pin mounting groove 61 on the described annular base 6, on the described pin mounting groove 61 pin 5 is installed; Also be provided with on the described annular base 6 to take out in six in slide block 1 and six and take out slide block 24, take out in every to take out in slide block 1 and every and all be shaped with pinhole 24 and protruding fan ring on the slide block 24, described pin 5 passes described pinhole 24.Take out in described slide block 1 and in take out slide block 24 formation circuluses spaced apart, take out slide block 24 in so-called both sides of taking out slide block 1 in referring to every spaced apart are, take out slide block 1 in the both sides of taking out slide block 24 in every are.12 protruding fan rings are configured for making the bulge loop 42 of pipe fitting back-off moulding,
Take out in described every and take out the inboard that slide block 24 is shaped with pinhole 24 ends in slide block 1 and every and also be shaped with fixture block, the fixture block 23 of taking out slide block 1 in described from described in to take out the fixture block thickness of slide block 24 different.Take out in described slide block 1 with in take out slide block 24 inside be provided with the copper band 3 that in moving process, can contact and make fixture block to rotate with described fixture block.Since in take out slide block 1 fixture block 23 to take out the fixture block thickness of slide block 24 different, therefore copper band 3 in moving process first larger with fixture block thickness slide block (in take out slide block 1 with in take out the wherein a kind of of slide block 2 4) contact and make its rotation, then the slide block less with fixture block thickness (in take out slide block 1 with in take out the wherein a kind of of slide block 2 4) contact and make its rotation so that slide block in take out and can carry out smoothly.
Described copper band 3 is fixedly connected with an end of connecting rod 11, the other end of described connecting rod 11 is fixed with oil cylinder pulling block 9, be fixed with on the described oil cylinder pulling block 9 for the oil cylinder connecting rod 10 that is connected with piston rod, one end of described fuse 1 is socketed with overcoat 7, be shaped with through hole on the described overcoat 7, described oil cylinder connecting rod 10 is positioned at described through hole, and described annular base 6 also is shaped be used to the through hole that passes oil cylinder connecting rod 10.
As the further optimization to technique scheme, be shaped with jack 12 on the described fuse 1, described overcoat 7 radially is equipped with thimble 8, and an end of described thimble 8 is positioned at described jack 12.
Take out in described slide block 1 and described in take out slide block 24 sliding contact surface be the monocline face.As shown in Figure 8, eight slide blocks of the prior art, owing to be in eight, to take out slide block to consist of, sliding contact surface 21 ' between its two slide block 2 ' must be made diclinic degree structure, namely all gradient on horizontal, vertical two directions among the figure, the processing of taking out slide block in this quite bothers, in Grinding Process, because the grinding angle of existing fixture for grinding machine generally all is unidirectional fixing, therefore need to successively grinding on the anchor clamps of two kinds of different machining angles, the manufacturing procedure trouble, manufacturing cost is high.And this mechanism consists of by taking out slide block in 12, sliding contact surface between two slide blocks can be made into the monocline face, it also is like this taking out in shown in Figure 7 is and taking out slide block 24 in slide block one 2(), as can be seen from the figure its contact-making surface 21 is the monocline face, namely laterally has gradient.The manufacturing of taking out slide block in this only needs through a grinding machine, and technique is simple, and manufacturing cost is also low.
More than describe preferred embodiment of the present invention in detail.Should be appreciated that those of ordinary skill in the art need not creative work and just can design according to the present invention make many modifications and variations.Therefore, all in the art technical staff on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should fall within the scope of protection of the present invention under this invention's idea.
