Description
Technical field
The present invention relates to mold closing mechanism fields, more particularly to a kind of high-speed high-precision mold closing mechanism.
Background technique
Mold closing mechanism is the linkage mechanism that will be used in injection molding machine, and current mold closing mechanism is broadly divided into two kinds, connecting rod
Formula clamping and double-plate matched mould apparatus, such as the entitled link-type injection molding machine clapper die spotting press of Patent No. CN201710152850
The patent of invention of structure, use be exactly link-type structure, the disadvantage is that adjust stress unanimously relatively difficult for four pull rods,
And four pull rod stress are again inconsistent after a period of work, influence the precision and the service life that entirely mold component, Er Qieqi
The piston diameter of Mode-locking oil cylinder is bigger, and open mold speed is slow, and in the final stage steel bushing and lock shaft of mode locking movement
Between have very high compression again, and have slide displacement, force of sliding friction is very big, easily causes fever and abrasion.
In addition, the patent of invention of the title double-plate matched mould apparatus such as Patent No. CN201711458696, use is just
It is fairly simple double-plate structure, the disadvantage is that the movement during mode locking is too many, Quick cylinder pulls to moving template first
Solid plate, then band-type brake nut obvolvent, then pressurizing cylinder play high pressure locking die, and three successively movements, centre is again there are two between
Disconnected movement, although the four pull rod stress of clamping for avoiding link-type are inconsistent and lock shaft and steel bushing wear problem,
It is long the time required to mode locking movement.
So above two clamping has the shortcomings that corresponding, a kind of new mould-matching structure for overcoming disadvantages mentioned above is needed
Generation.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of high-speed high-precision mold closing mechanisms, and structure is simple, set
The advantages of clamping and double-plate matched mould apparatus of link-type and the whole body, the service life is long, has saved the time of open mold.
The technical solution adopted by the present invention to solve the technical problems is: providing a kind of high-speed high-precision mold closing mechanism, wraps
The tailgate and solid plate positioned at both ends are included, is connected between the tailgate and solid plate by the pull rod of vertex, the drawing
It is socketed with moving template on bar, the promotion seat moved along pull rod, the promotion are provided between the moving template and tailgate
Seat is connected with the extension bar for the mould shifting oil cylinder for being mounted on one middle side part of tailgate, the two sides of the described promotion seat pass through link mechanism and
Moving template and tailgate are connected；
The side of the solid plate is equipped with the pressurizing cylinder being connected with one end of pull rod, and the pressurizing cylinder includes
The pressurised oil cylinder barrel being socketed between the front cover, rear cover and front cover and rear cover of pull rod one end, between the front cover and rear cover
The charged piston being connected with pull rod is installed, booster cavity is respectively formed between the charged piston and front cover and rear cover and is broken
Die cavity.
The link mechanism includes the rear free bearing being connected with tailgate and a pair of of back link for being rotatedly connected with rear free bearing, institute
The back link stated is rotatedly connected by small rod with seat is pushed, and being connected between the back link and front rod can outside sidesway
Dynamic connecting shaft, one end of the front rod and the preceding free bearing of one middle side part of moving template are rotatedly connected, and realize in moving template
Heart pressure.
As a supplement to the technical solution of the present invention, one end of the pull rod passes through charged piston and spiral shell
Line connection.
Further, the side of the charged piston is provided with stationary gland, and the stationary gland is same by screw
When be connected with the end face of charged piston and pull rod.
Further, the booster cavity of 4 pressurizing cylinders and broken die cavity pass through external pipeline and are interconnected.
The utility model has the advantages that structure is simple the present invention relates to a kind of high-speed high-precision mold closing mechanism, the molding of link-type is gathered
The advantages of mechanism and double-plate matched mould apparatus and the whole body, it is fewer by 40% or more than the open mold time of the clamping of link-type, than
The open mold time of the mold closing mechanism of double-plate few 50% or more；Since the booster cavity of four pressurizing cylinders is connected together, institute
It is completely the same with the stress of four pull rods.And the pressure of the booster cavity of pressurizing cylinder can be controlled accurately, make entirely to mold dress
It sets and reaches very high mode locking precision；Link mechanism realizes dynamic model using the eversion type link mechanism for connecting axially external movement
The center pressure effect of plate, the quadrangle pulling force of solid plate is completely the same, matches with the pressurizing cylinder on pull rod, reaches most perfect
Mold-locked state；Mode-locking oil cylinder original like that does not need to play high pressure.And it only needs to push template toward solid plate
It is mobile, thus lock shaft and steel bushing when sliding not by high compression, so lock shaft and steel bushing do not allow it is easy to wear；Mode locking oil
Thrust needed for cylinder is reduced to original 50% hereinafter, saving cost.
