【Specific embodiment】
The present invention will be described in detail below in conjunction with the accompanying drawings：
As illustrated, a kind of be easy to mould to return to location structure a little, the internal mould for being provided with forming cavity 2 is included
The screw thread formations 3 of tool molding assembly 1 and the threaded portion of shaped article 7, shaped article profile or internal other knots in forming cavity 2
Structure, the lower section of the screw thread formations 3 is provided with after being easy to the depanning of product 7, and the gear that screw thread formations 3 return to position is determined
Position device 4.
The gear positioning device 4 includes the first screw thread 41 for being located at the lower end of screw thread formations 3, in the thread forming
Travelling gear part 42 is cased with outside part 3, the driving cog gear member 42 is provided with the second screw thread 421 matched with the first screw thread 41,
During rotary transmission gear part 42, driving cog gear member 42 can be moved up and down with respect to line profiled member 3, and the lower end of driving cog gear member 42 sets
There is gear part 422, be provided with the side of driving cog gear member 42 and be meshed with gear part 422 and can drive what gear part 422 was rotated
Gear bar 43.Pull or promote gear bar 43, you can drive gear part 422 to rotate, so that driving cog gear member 42 can be with respect to line
Profiled member 3 is moved up and down.
The present invention can solve the inside back-off depanning of product 7, in the case of insufficient space.Existing mold has in interiors of products
In the case of back-off 71, it is impossible to smooth depanning, i.e., can not make inside has the product of back-off.
The mould molding component 1 includes and coordinate together the interior profiled member 11 of shaped article bottom and inside, be enclosed within
Middle profiled member 12, the screw thread formations 3 outside profiled member 11 are enclosed within outside middle profiled member 12, and the upper end of interior profiled member 11 is provided with
The back-off forming tank 112 of lower forming tank 111 and shaped article the inside back-off of shaped article bottom, in back-off forming tank 112
Fang Kaiyou contacts spacing lower limit portion 113 with middle profiled member 12, and the upper end of middle profiled member 12 is provided with and is connect with lower limit portion 113
Tactile upper limit portion 121, interior profiled member 11, middle profiled member 12, screw thread formations 3 top be provided with the top of shaped article 7 and
The upper profiled member 5 of outer shape.
The lower end of the interior profiled member 11 is provided with fixed part 114, and inwardly protruded spacer pin is provided with fixed part 114
115, i.e. spacer pin 115 are inserted into inside fixed part 114 by the mounting hole on fixed part 114, under the middle profiled member 12
End is provided with upper and lower and rotation the sliding groove 122 at the position of spacer pin 115, and the sliding groove 122 is included can make middle profiled member
12 move up and down slide up and down groove 1221, and make the rotational slide groove 1222 that middle profiled member 12 rotates.
The lower end of the middle profiled member 12 is additionally provided with holds driving cog gear member 42 and makes driving cog gear member 42 with middle profiled member 12
The pallet 123 for up moving.
After product 7 is molded, dynamical system up push up in profiled member 12, middle profiled member 12 slides up and down groove 1221 along spacing
Pin 115 moves up and down, and the pallet 123 of middle profiled member 12 also props up driving cog gear member 42 simultaneously, it is up moved together, while
Drive screw thread formations 3 up move together, middle profiled member 12, screw thread formations 3 make product 7 up move and with interior profiled member
11 are separated, and now, the back-off forming tank 112 for limiting the rotation of back-off 71 of product 7 is also separated with product 7；Then, dynamical system
Profiled member 12 in continuing up to push up, the rotational slide groove 1222 of middle profiled member 12 rotates along spacer pin 115 and moves up and down, while tooth
Wheel bar 43 is rotated to the direction of setting, i.e., band nutating gear part 42 is rotated on screw thread formations 3, makes the phase of driving cog gear member 42
Screw thread formations 3 are moved upwards so that pallet 123 is not transmitted gear member 42 and limits, i.e., screw thread formations 3 will not be transported upwards
It is dynamic, the smooth depanning in the part of screw thread formations 3 on product 7 is realized, during this, height is not in vertical height for gear bar 43
Become, driving cog gear member 42 can upwards move one end distance, should ensure that the tine length S of gear bar 6 is more than or equal to driving cog gear member
42 tine length L and the ultimate range sum up moved, it is ensured that two gears do not fall off.
After depanning, as long as ensureing the reduction of mould by position before gear bar 43 is reverted into depanning, accurate positioning,
It is easy to regulation.Gear bar 43 in only the horizontal direction on move forward and backward, can be by gear bar 43 and other motionless contacts in frame
Mark is carried out in position, and when the mark position of gear bar 43 reaches contact position, i.e., mould returns to initial position, you can cast
Next product of production.
