Description
Technical field
The invention belongs to injection mold fields, specifically disclose a kind of ejecting mechanism for engine flip lid injection mold.
Background technique
Injection mold is widely applied a kind of molding die in plastic part production, and it is complete to be also to confer to plasthetics
The tool of structure and accurate dimension, injection molding are a kind of processing methods used when producing certain complex-shaped components in batches.
Injection mold is made of moving mold and fixed mold two parts, and moving mold is mounted on the moving die plate of injection (mo(u)lding) machine, fixed mold
It is mounted on the fixed form of injection (mo(u)lding) machine.In injection moulding, moving mold and fixed mold closure constitute running gate system and chamber
Room, by the plastics after hot melt by forming required product by being cooled and shaped in running gate system injecting chamber.Dynamic model when die sinking
Tool is separated with fixed mold to take out plastic products.
The mandril of ejecting mechanism is located in chamber, when product is cooled and shaped, will appear adhesion between mandril and product
Situation, it is possible that unbalance stress, scratch occurs so as to cause the surface of product when manually removing.
Summary of the invention
The invention discloses it is a kind of for engine flip lid injection mold ejecting mechanism, its object is to solve mandril with
Adhesion problems between product.
To solve the above problems, basic scheme of the invention are as follows: for the ejecting mechanism of engine flip lid injection mold, packet
Several horizontal positioned shafts being set between fixed mold and pedestal are included, shaft is parallel to each other, and one group is distributed in shaft
One cam；The second cam, the distal end of the first cam distal end outer profile and the second cam are provided between the first adjacent cam
At angle between outer profile；Be equipped with cylinder above the top of first cam and the second cam, cylinder include the first cylinder with
Second cylinder, the first cylinder are located at the surface of the first cam, and the second cylinder is located at the surface of the second cam；The cylinder body of cylinder
It is each attached to the lower surface of fixed mold；The piston rod of cylinder is passed down through piston plate and cylinder body, piston rod respectively with it is corresponding
Cam offsets；It is installed with reset spring between the inner wall upper end of cylinder block and piston plate, is provided with air inlet in the middle part of piston rod
Hole, air inlet are located at the top of piston plate, and the equal face setting in the upper end of piston rod is there are two venthole obliquely, in piston rod
Portion is equipped with pipeline, and air inlet is connected to venthole by pipeline；The left end of shaft is equipped with intermeshing gear, and first turns
The left end of axis is connected with the output shaft of motor.
The basic principle of this programme are as follows: after the product in mold is cooled and shaped, moving mold is separated, starts motor.
Motor drives first shaft to rotate clockwise by output shaft, and first shaft is driven by meshed gears,
To which drive shaft rotates synchronously, the rotation of shaft drives the first cam to rotate clockwise with the second cam；Due to the first cam
At angle between distal end outer profile and the second cam distal end outer profile；Therefore, it is clockwise while the first cam is with the second cam
When rotation, the distal end outer profile of the first cam is contacted with the First piston bar of the first cylinder first.
When the farthest outer profile of First piston bar and the first cam contacts, First piston bar stress is moved upwards, and first
Product is ejected chamber by piston rod；First piston bar drives first piston plate to move upwards, and first piston plate squeezes the upper of cylinder
The pressure of half chamber, upper half chamber increases, and gas is influenced to flow into from air inlet, be flowed from venthole through pipeline by pressure
Out；Meanwhile first piston plate pressed home spring, reset spring generate deformation compression.
When First piston bar is detached from and the distal end outer profile of the first cam contacts, reset spring loses squeezing for first piston plate
Pressure, reset spring start to restore deformation and first piston plate are pushed to move downward, and it is downward that first piston strip moves First piston bar
Movement.
While First piston bar moves downward, second piston bar moves upwards under the promotion of the second cam；At this time
Two piston plates squeeze the upper half chamber of cylinder, and the pressure of upper half chamber increases, and gas is influenced to flow into from air inlet by pressure,
It is flowed out from venthole through pipeline, gas flows to the lower surface of product；Meanwhile second piston plate pressed home spring, it resets
Spring generates deformation compression；When First piston bar is parallel with the upper surface of second piston bar, product is pushed by second piston bar
It continues up, the gas that the second push rod collides when contacting with product, and flows out from venthole applies product oblique
It upwards pressure, buffering collision of closed is achieved the effect that with this.
After worker removes product, second piston bar disengaging is contacted with the distal end outer profile of the second cam, and reset spring loses
The extruding of first piston plate is gone, reset spring starts to restore deformation and second piston plate is pushed to move downward, second piston strip
Dynamic second piston bar moves downward.
Until close motor when First piston bar and second piston bar are restored to original state, continue to be molded next time
Processing.
For compared with the existing technology, piston rod is divided into twice ejection upwards in this programme, using the two alternating movement,
Firmly uniformly mandril can be separated with product；And according to the quantity of piston rod setting and position, it can reach and more balance
Application active force, prevent from damaging product.
It is first contacted when piston rod in this programme is contacted with product using air-flow, forms air-flow buffer layer, avoid piston rod
The excessive velocities of movement and the dynamics of shock that generates is larger, to cause to damage to product；Meanwhile air-flow is contacted with product
When, it can cool down again to product, when avoiding worker's pickup, product temperature is excessively high and scalds.
Further, the upper end of piston rod is circumferentially evenly distributed with multiple ventholes.
Uniformly venthole respectively, more evenly, range is wider for the air flow method of generation, and buffering effect is more preferably；Gas simultaneously
The range of stream is wider, wider to the range to cool down with product.
Further, the bottom end office of piston rod is provided with cushion.
When cushion is moved downward for piston rod, shock when reducing with cam contact reduces piston rod and cam
Abrasion, to increase the service life of piston rod and cam.
Further, the transmission ratio of gear is one to one.The synchronous rotation between shaft is realized, to ensure that cam jacks up
The time consistency of piston rod, the height for avoiding the occurrence of piston rod is uneven, and product is easily tilted and fallen.
Further, cam is disk cam.For disk cam when jacking up piston rod, the vibration generated in the process is smaller, avoids producing
Product are vibrated to be fallen.
