Description
Technical field
The utility model 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
The technical problem to be solved by the utility model is to provide a kind of high-speed high-precision mold closing mechanisms, and structure is simple, collection
The advantages of having closed the 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 scheme adopted by the utility model to solve the technical problem is as follows: providing a kind of high-speed high-precision molding dress
It sets, tailgate and solid plate including being located at both ends are connected between the tailgate and solid plate by the pull rod of vertex, described

Seat is pushed to be 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 promotion seat pass through connecting rod machine
Structure is connected with moving template and tailgate；
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 kind of supplement to technical solution described in the utility model, one end of the pull rod passes through charged piston
And it is threadedly coupled.
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, has gathered link-type the utility model relates to a kind of high-speed high-precision mold closing mechanism
The advantages of clamping and double-plate matched mould apparatus and all over the body, it is fewer by 40% than the open mold time of the clamping of link-type with
On, it is fewer by 50% or more than the open mold time of the mold closing mechanism of double-plate；Since the booster cavity of four pressurizing cylinders is connected to one
It rises, so the stress of four pull rods is completely the same.And the pressure of the booster cavity of pressurizing cylinder can be controlled accurately, make entirely to close
Mold device reaches very high mode locking precision；Link mechanism is realized using the eversion type link mechanism for connecting axially external movement
The center pressure effect of moving template, the quadrangle pulling force of solid plate is completely the same, matches, reaches most with the pressurizing cylinder on pull rod
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 past fixed
Template movement, 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；Lock
Thrust needed for mould oil cylinder is reduced to original 50% hereinafter, saving cost.
