When, the distance of retrogressing becomes apparent.General cylinder slide block, which is all straight takes out, also into 90 degree of pumpings, and useful check valve is controlled
System, or controlled by fixture block, but currently existing scheme is all not perfect or mold is complicated and cannot thoroughly be solved
Retreat phenomenon.
Invention content
The present invention is directed to solve at least one of the technical problems existing in the prior art or related technologies.
For this purpose, it is an object of the invention to propose a kind of mold.
In view of this, purpose according to the present invention, it is proposed that a kind of mold, which is characterized in that including：Hydraulic cylinder, setting
In template；Internal model is arranged in template；Slide guide item, slide guide item are connected with the piston rod of hydraulic cylinder, are provided on slide guide item
Slideway, the slide guide item end face opposite with slideway are in contact with internal model；Sliding block, sliding block are connected with slide guide item, and sliding block can be along slideway
Sliding, sliding block one end opposite with slide guide item is matched with internal model；Travel switch is arranged in template, is located at slide guide item and liquid
Between cylinder pressure；Block is switched, switch block is arranged on one end in slide guide item towards hydraulic cylinder；Wherein, block and stroke are switched
Switch matches, and is used to indicate the working condition of mold.
According to mold provided by the invention, mold is kept off by hydraulic cylinder, internal model, slide guide item, sliding block and travel switch and switch
Block forms, and template is the general name of mold frame body and shell, and the dynamical element as the mold is arranged in template in hydraulic cylinder；Internal model
Inner workings for carrying mould are set in template；Slide guide item is arranged in template, the piston of one end and hydraulic cylinder
Bar is connected, and the other end is provided with slideway, and the slide guide item end face opposite with slideway is in contact with internal model；Sliding block is arranged in internal model
It is connected with slide guide item, sliding block can be slided along slideway, and sliding block one end opposite with slide guide item is matched with internal model.In the knot
In structure, hydraulic cylinder is connected with slide guide item, and slide guide item is connected by slideway with sliding block, and the piston rod of hydraulic cylinder is made to be not directly contacted with cunning
Block, when mold executes injection molding work, the sliding block being in contact with injected plastics material can be by very strong injection molding expansive force, and expansive force is logical
Crossing slideway and being transferred to makes slide guide item be somebody's turn to do by the active force of vertical direction and by itself rigidly offsetting for slide guide item in slide guide item
Active force, the motive force for making hydraulic cylinder not brought by injection molding expansive force in injection moulding process, to avoid sliding block from being molded
It is reversed phenomenon in the process, ensures the planarization and synchronism of injection-molding surfaces, prevents product from the case where peak and segment difference occur, rises
It is molded stability to improving, injection molding quality is improved, promotes the technique effect of product reliability.Meanwhile travel switch is arranged in mould
On plate, between slide guide item and hydraulic cylinder, when mold work, hydraulic cylinder drives slide guide item and switch block to be moved up in internal model
Dynamic, mobile switch block is matched with travel switch, and user is allow to learn slide guide item by travel switch feedack
Motion state, and the working condition of mold is further learnt, to facilitate working condition real-time control of the user according to mold
Mold works, and realizes and promotes intelligent product degree, promotes the technique effect of user experience.
Specifically, mold, in injection molding process, injected plastics material will produce larger expansive force, sliding block needs to fight at this time
The expansive force makes injected plastics material form specified shape under the restriction of mold.Sliding block is directly connected with hydraulic cylinder in existing mold
