Description
Technical field
This utility model is related to technical field of mold, specially a kind of mold liftout attachment of car boot box bracket.
Background technology
Car boot box bracket is mainly used in the article placed in bearing automobile luggage compartment, and case holder is in manufacture process
In, usually it is integrally formed using mould, but traditional mould, when case holder is produced, case holder is readily adsorbed in
On mould, cause the demoulding difficult.
In order to solve the above problems, mold liftout attachment is provided with the mould of some production case holders, including
Wedge block and the ejector retainner plate on front side of wedge block inclined-plane, wedge block lower section is provided with the slide rail slided for wedge block,
The some thimbles for ejection die are provided with above ejector retainner plate, back-moving spring is arranged with outside thimble, also set on wedge block
There is the returning device of control wedge block return, the function of the returning device is realized by return spring, such scheme
Although solving the problems, such as that the demoulding is difficult, wedge block carries out return, this structure by return spring in use
In use for some time return spring will extremely be easily damaged so that the return of wedge block is unreliable, and then affect whole
The reliability of liftout attachment work.
Utility model content
This utility model is intended to provide a kind of car boot box bracket that wedge block return reliability can be effectively ensured
Mold liftout attachment.
The mold liftout attachment of the car boot box bracket in this programme, including wedge block and positioned at wedge block inclined-plane
The ejector retainner plate of front side, wedge block lower section is provided with the slide rail slided for wedge block, is provided with above ejector retainner plate for ejecting mould
Some thimbles of tool, are arranged with back-moving spring outside thimble, the returning device of wedge block, return are also slidably connected on slide rail
Device includes return block, and first through hole and the second through hole are offered on return block, and the width of first through hole is more than the second through hole
Width, is provided with permanent magnet in first through hole, and being additionally provided with first through hole can be along the electromagnetic block of first through hole movement, electromagnetic block
One end is located in first through hole, and the electromagnetic block other end stretches into the second through hole, and electromagnetic block is provided with magnet exciting coil, on wedge block
Force sensing resistance is additionally provided with, force sensing resistance is electrically connected with the magnet exciting coil on electromagnetic block.
Force sensing resistance is a kind of pressure-dependent resistance of resistance, in this programme, when acting on the pressure on force sensing resistance
When power is big, the resistance of force sensing resistance also increases, and when the pressure hour on force sensing resistance is acted on, the resistance of force sensing resistance also subtracts
It is little.
The principle of this programme is：When ejection die is needed, external force is acted on wedge block this programme, is now placed in wedge
Force sensing resistance on shape slide block will be acted on by external force, due to the pressure on force sensing resistance it is big when, its resistance is also big, now with
The magnet exciting coil of force sensing resistance electrical connection is in off-position, and electromagnetic block does not have magnetic force, and permanent magnet attracts electromagnetic block to fit with it,
Wedge block slides in the presence of external force along slide rail, and during slip, inclined-plane and the ejector retainner plate of wedge block interact,
Ejector retainner plate is moved up in the presence of wedge block, and then causes thimble ejection die.
After thimble ejection die, wedge block needs return, now removes the external force acted on wedge block, wedge shape
The resistance of force sensing resistance will reduce on slide block, and the magnet exciting coil for now electrically connecting with force sensing resistance will be powered, and magnet exciting coil is powered
To cause electromagnetic block that there is electromagnetic force afterwards, the magnetic force that the electromagnetic force is produced with permanent magnet is mutually exclusive, in the effect of the repulsive force
Under, electromagnetic block is moved along first through hole, and electromagnetic block will protrude above return block during movement and give wedge block one
Active force, the active force will cause wedge block to move to inceptive direction, when electromagnetic block in the presence of repulsive force continuously along the
When one through hole is moved, wedge block just will continue to inceptive direction movement, until wedge block is returned in the presence of electromagnetic block
Till initial position.
This programme advantage compared with prior art is：This programme replaces return spring to realize wedge shape using electromagnetic block
The self-return of slide block, due to not using flimsy return spring, therefore this programme can be effectively ensured wedge block return
Reliability, and then ensure the reliability of liftout attachment work.
Further, electromagnetic block includes the first electromagnetic block and the second electromagnetic block, and the width of the first electromagnetic block is more than the second electromagnetism
The width of block, and the width of the first electromagnetic block, more than the width of the second through hole, magnet exciting coil is located on the first electromagnetic block.
Electromagnetic block is divided into into the first electromagnetic block and the second electromagnetic block, when wedge block is resetted, to the first electromagnetic block
On magnet exciting coil be powered, the first electromagnetic block has electromagnetic force, mutually exclusive between the electromagnetic force and the magnetic force of permanent magnet, at this
In the presence of repulsive force, the first electromagnetic block drive the second electromagnetic block along first through hole move, due to the width of the first electromagnetic block it is big
In the width of the second through hole, therefore the second through hole has position-limiting action to the first electromagnetic block, leads to when the first electromagnetic block moves to second
During the position in hole, wedge block is just pushed to initial position by the second electromagnetic block, so as to ensure that the accurate of wedge block
Reset.
Further, magnet exciting coil is direct-flow magnet exciting coil.Noise, pulsation of the direct-flow magnet exciting coil compared with AC excitation coil
Little, service behaviour is more reliable and more stable.
Further, thimble is two, and two thimbles are symmetrically distributed in the two ends of ejector retainner plate.When by mould ejection, two
Individual thimble gives respectively mould one active force from both sides, so as to mould can be subject to more uniform active force in ejection, together
When also cause mould ejection when stress it is more steady.
Further, the length of the second through hole is 1/10th of first through hole length, and the length of the first electromagnetic block is second
/ 10th of electromagnetism block length.The size causes the first electromagnetic block when moving along first through hole with enough spaces, protects
The accurate return of wedge block is demonstrate,proved.
