Abstract
The invention discloses an arc core-pulling device for a die, which mainly comprises a movable die insert panel, a teeth row oil cylinder, a teeth row, a fixed gear, a movable gear, a U-shaped gear and a bending core, wherein the movable die insert panel is installed on a movable die, a rod end of a piston rod of the teeth row oil cylinder is connected with the teeth row, the fixed gear is rotatably installed on the movable die insert panel, and the U-shaped gear is installed in the movable die and located below the movable die insert panel; and the movable gear is rotatably connected with one end of the bending core, the outer teeth of the movable gear are respectively engaged with the outer teeth of the fixed gear and the arc inner teeth of the U-shaped gear, and the bending core is slidably connected to the interior of a bending groove of the movable die insert panel. Because the U-shaped gear is provided with the arc inner teeth, the movable gear engaged with the U-shaped gear moves along an arc inner teeth surface to drive the bending core to be stably pulled out from a die cavity. The fixed gear, the movable gear and the U-shaped gear are engaged with each other to realize power transmission as well as stable and reliable running.
Description
Technical field
The present invention relates to a kind of injection mold, particularly relate to a kind of mould arc core-pulling device.
Background technology
Plastics injection mould is the instrument of producing plastic products, uses very extensive.In plastic products injection moulding, because there are indent, side channel, side opening etc. in the inside of some plastic products, mold cores need be set and by the mode of loosing core mold cores be taken out after moulding at plastic part.The mode that mould of plastics is loosed core is a lot, but less for the extraction mode with radian hole, and the dealer is badly in need of the extraction mechanism of a kind of energy convenience, stable, reliable arc core.
Summary of the invention
The object of the present invention is to provide a kind of mould arc core-pulling device reliable and stable, that overlap is few that moves.
For achieving the above object, technical solution of the present invention is:
The present invention is a kind of mould arc core-pulling device, and it mainly is made up of dynamic model panel, tooth row oil cylinder, tooth row, fixed gear, free gear, U-shaped gear, curved core; Described dynamic model panel is installed on the dynamic model, and the tooth row cylinder block is installed in the outside of dynamic model, and the rod end of the piston rod of tooth row oil cylinder is connected with tooth row one end, and the activity of tooth row body is arranged on the die joint of dynamic model; Described fixed gear is rotatable to be installed on the dynamic model panel, and U-shaped gear is installed in the dynamic model and is positioned at the below of dynamic model panel; Described free gear is rotatable to be connected with an end of curved core, the other end of curved core is core, the external tooth of free gear respectively with the engagement of the arc inner tooth of the external tooth of fixed gear, U-shaped gear, offer the curved groove of arc at the dynamic model panel, curved core slips in the curved groove of dynamic model panel and can move around along curved groove.
The present invention also comprises dynamic model fuse, side oil pumping cylinder, side core-pulling; Described dynamic model fuse is fixed in the dynamic model as the part of die cavity; The cylinder body of described side oil pumping cylinder is installed on the dynamic model, the opposite side relative with the tooth row oil cylinder, and side is pumped, and the rod end of piston rod of cylinder is connected with side core-pulling and this side core-pulling slips on the dynamic model panel.
After adopting such scheme, because U-shaped gear of the present invention has arc inner tooth, can move along the arc inner tooth face with the free gear of its engagement, drive curved core and extract out from mold cavity stably.Fixed gear, free gear, U-shaped gear are being meshing with each other between the gear, realize the transmission of power, operate steadily, reliably, and curved core mold die cavity cooperates closely, and the gap is little, and overlap is few, preferably resolves the problem of loosing core of arcuate socket.
The present invention is further illustrated below in conjunction with the drawings and specific embodiments.
Description of drawings
Fig. 1 is cutaway view of the present invention;
Fig. 2 is the figure of loosing core after the die sinking of the present invention.
The specific embodiment
As shown in Figure 1, the present invention is a kind of mould arc core-pulling device, and it mainly is made up of dynamic model panel 1, tooth row oil cylinder 2, tooth row 3, fixed gear 4, free gear 5, U-shaped gear 6, curved core 7, dynamic model fuse 8, side oil pumping cylinder 9, side core-pulling 10.
Described dynamic model panel 1 is installed on the dynamic model 20, and tooth row oil cylinder 2 cylinder bodies are installed in the outside of dynamic model 20, and the rod end of the piston rod of tooth row oil cylinder 2 is connected with an end of tooth row 3, and the body activity of tooth row 3 is arranged on the die joint of dynamic model 20.
Described fixed gear 4 rotatable being installed on the dynamic model panel 1, U-shaped gear 6 are installed in the dynamic model 20 and are positioned at the below of dynamic model panel 1; One end of described free gear 5 rotatable and curved cores 7 is connected, the other end of curved core 7 is mold cores, the external tooth of free gear 5 meshes with the external tooth of fixed gear 4, the arc inner tooth of U-shaped gear 6 respectively, offer the curved groove 11 of arc at dynamic model panel 1, curved core 7 slips in the curved groove 11 of dynamic model panel 1 and can move around along curved groove 11.
Described dynamic model fuse 8 is fixed in the dynamic model 20 as the part of mold cavity; The cylinder body of described side oil pumping cylinder 9 is installed on the dynamic model 20, the opposite side relative with tooth row oil cylinder 2, and side is pumped, and the rod end of piston rod of cylinder 9 is connected with side core-pulling 10 and side core-pulling 10 slips on dynamic model panel 1, and the end of this side core-pulling 10 is mold cores.
Operation principle of the present invention:
With reference to shown in Figure 2, when die sinking, dynamic model 20 separates with cover half 30,2 actions of tooth row oil cylinder, tooth row 3 is outwards mobile along die joint, fixed gear 4 rotations of drive and its engagement, and fixed gear 4 drives the free gear 5 with its engagement, the arc inner tooth engagement of free gear 5 and U-shaped gear 6 is also moved along the arc inner tooth of U-shaped gear 6, and connected curved core 7 is extracted out from the arcuate socket of product 50.
Emphasis of the present invention just is: adopt the cooperation of fixed gear, free gear, U-shaped gear.
The above, only for preferred embodiment of the present invention, so can not limit scope of the invention process with this, i.e. the equivalence of doing according to the present patent application claim and description changes and modifies, and all should still belong in the scope that patent of the present invention contains.
