Description

A kind of human body inductive lamp lampshade injection forming mold with moving back internal threaded mechanisms
Technical field
The invention belongs to die apparatus technical field, especially relating to a kind of human body inductive lamp lampshade injection forming mold with moving back internal threaded mechanisms.
Background technology
Injection mold is the one in mould, application very general, especially uses at most at some working of plastics products of making.Such as be with female human body inductive lamp lampshade, at present for the production of the mould with this series products, some adopts hydraulic motor as Power Component, in depanning mould assembling action, be used for moving back the power of screw thread, in the upper and lower rotary motion of threaded rod of forming thread, spacing and the spacing difficult point maximum often of precession of the back-out of threaded rod, motor does not have brake gear, complete in oil pressure actuated, oil pressure is closed, the effect that motor also can fall by oil pressure continues to rotate, and finally stops by force by two thrust bearings that thread core (mold insert of shaped article screw thread) is upper and lower.There is following shortcoming:
1, during matched moulds, thread core upper end and die is easily made to rotate tension.
2, during die sinking, make thread core lower end with thread bush tension.
3, when next hydraulic motor works on, thread core may be killed, and causes motor to turn motionless;
4, thread core upper end and die rub excessively, and product produces overlap.
5, stop by force, gear, thread core, thread bush and bearing all can shake wound and shatter, and cause part to shorten service time, frequently repair a die, and impact is produced, and affects the bulk life time of mould.
Above consequence all by repair a die and renewal part solves, must bring very large impact to production, the cost that repairs a die that also to have allowed producer pay very large.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of human body inductive lamp lampshade injection forming mold with moving back internal threaded mechanisms, matched moulds and die sinking, by cutting off power transmission voluntarily timely, avoid each parts to shake wound to shatter, also guarantee thread core to move up and down in process can not with the situation of die generation tension, in the effective guarantee mold use life-span, save maintenance and open money.
The technical solution used in the present invention is: a kind of human body inductive lamp lampshade injection forming mold with moving back internal threaded mechanisms, comprises the thread core of upper die and lower die and shaped article screw thread, and upper die and lower die laminating forms formed product chamber; Described counterdie comprises float plate and base plate from top to bottom, is provided with elastic parts between described float plate and base plate; Product circumference is spacing in float plate, and thread core is positioned at counterdie and upper end is positioned at the formed product chamber at float plate place, and thread core can rotate in a circumferential direction and be engaged in counterdie; Thread core side is provided with the tooth bar running through upper die and lower die, and thread core and tooth bar be arranged in parallel, and tooth bar one end is connected with press, is connected between tooth bar and thread core by power transfer assembly, and tooth bar makes thread core to rotate in a circumferential direction motion.
Described power transfer assembly comprises the first bevel gear, the second bevel gear, several bearings, connecting axle, gear, described thread core overcoat has bearing, this bearing and be arranged in base plate, first bevel gear is enclosed within thread core, second bevel gear and gear are connected together through connecting axle, connecting axle is provided with gear and this gear is arranged in base plate, first bevel gear and the engagement of the second bevel gear, first bevel gear and the second bevel gear are at right angles arranged, gear and tooth bar engagement, connecting axle is vertical with tooth bar to be arranged.
Described product circumference is spacing refers to that in float plate float plate shows saw-tooth ring in edge's annular row in formed product chamber, and saw-tooth ring to be positioned at outside thread core upper end and to be positioned at product lower limb.
Described elastic parts is helical spring.
The invention has the beneficial effects as follows: a kind of human body inductive lamp lampshade injection forming mold with moving back internal threaded mechanisms of the present invention, with power transfer assembly, in matched moulds and die sinking, masterpiece when to be pulled open to mould by press or close is power, is a kind of Transformation Application of pure mechanical force.And the matched moulds of this power follower mould or the stopping of die sinking stop, and can be stopped by power, there is not the strength of a buffered excess in the very first time.So the power transfer assembly of the present invention's design, can realize synchronous with the action of press, avoid each parts to shake wound and shatter, also guarantee thread core to move up and down in process can not with the situation of die generation tension, in the effective guarantee mold use life-span, save maintenance and open money.

Detailed description of the invention
Shown in Fig. 1-Fig. 4, a kind of human body inductive lamp lampshade injection forming mold with moving back internal threaded mechanisms, comprises the thread core 2 of upper die and lower die and shaped article 1 screw thread, and upper die and lower die laminating forms product 1 forming cavity; Described counterdie comprises float plate 3 and base plate 4 from top to bottom, is provided with elastic parts 5 between described float plate 3 and base plate 4; The object that elastic parts 5 is arranged, because thread core 2 and product 1 are screwed together, and thread core 2 maintenances rotate in a circumferential direction, so when thread core 2 rotates, product 1 be allowed to move upward, so design flexibility assembly 5, when the demoulding, the pressure that float plate 3 upper end is subject to slowly is removed, and version 3 of floating drives product 1 moving upward slowly under the effect of elastic parts 5, can be separated like this with thread core 2.
Product 1 circumference spacing in float plate 3 because time product 1 moves upward, thread core 2 rotate, so report allow product 1 not rotate, guarantee two can depart from smoothly.
Thread core 2 is positioned at counterdie and upper end is positioned at product 1 forming cavity at float plate 3 place, and thread core 2 can rotate in a circumferential direction and be engaged in counterdie; Thread core 2 side is provided with the tooth bar 6 running through upper die and lower die, and thread core 2 and tooth bar 6 be arranged in parallel, and tooth bar 6 one end is connected with press, is connected between tooth bar 6 and thread core 2 by power transfer assembly, and tooth bar 6 makes thread core 2 to rotate in a circumferential direction motion.
Described power transfer assembly comprises the first bevel gear 7.1, second bevel gear 7.2, several bearings 7.3, connecting axle 7.4, gear 7.5, described thread core 2 overcoat has bearing 7.3, this bearing 7.3 and be arranged in base plate 4, first bevel gear 7.1 is enclosed within thread core 2, second bevel gear 7.2 and gear 7.5 are connected together through connecting axle 7.4, connecting axle 7.4 is provided with gear 7.5 and this gear 7.5 is arranged in base plate 4, first bevel gear 7.1 and the second bevel gear 7.2 engage, first bevel gear 7.1 and the second bevel gear 7.2 are at right angles arranged, gear 7.5 and tooth bar engagement, connecting axle 7.4 is vertical with tooth bar 6 to be arranged.
Described product 1 circumference is spacing refers to that in float plate 3 float plate 3 shows saw-tooth ring 8 in edge's annular row of product 1 forming cavity, and saw-tooth ring 8 to be positioned at outside thread core 2 upper end and to be positioned at product 1 lower limb.
Described elastic parts 5 is helical spring.
Operation principle of the present invention is: after mold-closing injection, press drives patrix and tooth bar 6 to move, the pressure that float plate 3 upper end is subject to slowly is removed, version 3 of floating drives product 1 moving upward slowly under the effect of elastic parts 5, rotate with hour rack 6 driven gear 7.5, gear 7.5 drives the second bevel gear 7.2 to move, second bevel gear 7.2 drives the first bevel gear 7.1 to rotate, first bevel gear 7.1 drives thread core 2 to rotate, thread core 2 is while rotate, float plate 3, while move upward, can be separated with thread core 2 like this.
