Structure.
Background technology
In existing injection mould structure, the most modes frequently with pivot stud of screw thread core pulling utilize push pedal side
The ejection of product side is promoted to take out tooth, so that the need for product comes off, but this structure can not meet all moulds, in front and rear mould
While being required for taking out tooth, front and rear mould is done pulled core structure by the way of pivot stud and is difficult to mold, and thimble is needed when exhausting tooth
Or during ejector sleeve ejection, then also need to make thread core draw back, then ejected with thimble or ejector sleeve, in the mode of pivot stud
Thread core can not be moved, ejection apart from short, and in the processing of different product thread core stretch into it is deep inside die cavity
Spend inconsistent, it is necessary to set different thread core structures, add production cost.
Utility model content
The purpose of this utility model be overcome weak point of the prior art there is provided one kind it is simple in construction, easy to operate
Make the mechanism of thread core retrogressing with large-duty use facing is carried.
In order to solve the above technical problems, the utility model is solved by following technical proposals：
A kind of use facing makes the mechanism that thread core is retreated, and inside mold cavity, the use facing makes thread
Core withdrawing mechanism includes thread core, cylindrical type facing, rack and travelling gear, and the travelling gear is located at the thread type
The side of core, the thread core includes cylinder and is arranged on the forming thread end and connection screw thread end at cylinder two ends, it is described into
The type end of thread is inside die cavity, and the central axis of the facing is provided with internal thread hole, and the facing is arranged by internal thread hole
In the threaded ends of thread core, the travelling gear includes the first travelling gear and the second travelling gear being coaxially disposed,
The driven gear engaged with the first travelling gear, the second driving cog wheel and rack are additionally provided with the cylinder of the thread core
Engagement connection, the upper surface of the facing is provided with some adjustment holes around facing central shaft circumferential arrangement, the adjustment hole
Provided with pin, the facing is fixedly connected in rear mold by pin.
Specifically, one end of the rack is provided with pusher cylinder.
Specifically, mould is provided with pin hole, the pin is inserted in pin hole through adjustment hole.
Specifically, the use facing makes thread core withdrawing mechanism include two thread cores and two facings
The utility model has advantages below and beneficial effect compared with prior art：The utility model passes through rack drives tooth
The design of set solves the problem of rotary type core pulling of thread core original place is difficult to die sinking, thread core while ejecting product
Setback is done, die sinking space and ejection distance is added, is stretched into while changing thread core by the regulation of facing position
Depth in die cavity, it is easy to adjust, and drive thread core to screw out by the rotation of rack when taking out thread core, without
Manually twisted, save manpower, realized that die automation is produced, improve production efficiency.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and detailed description.
Fig. 1 is the structural representation for the mechanism that a kind of use facing of the utility model makes the retrogressing of thread core.
Embodiment
The utility model is described in further detail with reference to embodiment and accompanying drawing, but implementation of the present utility model
Mode not limited to this.
As shown in figure 1, a kind of use facing makes the mechanism that thread core is retreated, it is described to adopt inside the die cavity of mould
Thread core withdrawing mechanism is set to include thread core 1, cylindrical type facing 2, rack 3, travelling gear 4, the driving cog with facing
Wheel 4 is located at the side of the thread core 1, and the thread core 1 includes cylinder 101 and is arranged on the screw thread at the two ends of cylinder 101
Forming ends 102 and threaded ends 103, the thread forming end 102 is inside die cavity, and the central axis of the facing 2 is set
There is internal thread hole, the facing 2 is set in the threaded ends 103 of thread core 1, the travelling gear 4 by internal thread hole
Including the first travelling gear 401 and the second travelling gear 402 being coaxially disposed, it is additionally provided with the cylinder 101 of the thread core 1
Engaged with the first travelling gear 401 driven gear (not marked in diagram), second travelling gear 402 engages with rack 4
Connection, the upper surface of the facing 2 is provided with some adjustment holes 201 around the central shaft circular arrangement of facing 2, the adjustment hole
Pin (unmarked in diagram) is provided with 201, the facing 2 is fixedly connected in rear mold by pin.Using facing 2 to thread
The position of core 1 and height are fixed, and improve the controllability of thread core, thread core 1 is stretched into inside die cavity
Depth be adjusted, so as to control the depth of thread on product.
Specifically, one end of the rack 4 is provided with pusher cylinder (unmarked in diagram), rack is controlled using pusher cylinder
Motion.
Specifically, mould is provided with pin hole, the pin is inserted in pin hole through adjustment hole 201.Pass through pin pair
Facing 2 is fixed.
Specifically, the use facing makes thread core withdrawing mechanism include two thread cores 1 and two facings 2.Mould
Tool improves the processing efficiency of product provided with two die cavities.
Specific implementation process of the present utility model is as follows：
Embodiment：The utility model is to drive the second travelling gear 402, the first travelling gear 401 and second by rack 3
