[ field of technology ]
The invention relates to the technical field of dies, in particular to a mechanism for preventing a slider spring from deforming.
[ background Art ]
The slide block is an indispensable existence in the current mold technology, is a mold assembly sliding in a mold, and can move according to the mold closing direction or the mold opening and closing direction according to different mold designs, so as to drive or push other parts; in the prior art, when a slide block spring is used, the spring positioning pin for preventing the slide block spring from deforming is fixed in specification, and the length cannot be increased, so that all the slide block springs cannot be protected, and the slide block is easy to crush the slide block spring when a mold is opened and closed; in addition, since the spring positioning pin with fixed specification needs to be purchased in particular, the purchase cost is huge for a long time; the spring locating pin with the fixed specification is used, so that the whole die is complex to process and difficult to assemble, and when the spring locating pin is used, the die is required to be maintained frequently, the production efficiency is delayed, the maintenance cost is high, and the product quality is more likely to be influenced.
Therefore, there is a need for improvements over the prior art.
[ invention ]
The invention aims to solve the technical problems that: at present, when a spring positioning pin with fixed specification is used, the assembly is difficult, the situation that a sliding block crushes the sliding block spring is easy to occur, and the problems of high maintenance cost, delay production efficiency and the like of a die are caused.
The invention solves the technical problems as follows: a mechanism for preventing deformation of a slider spring, comprising: the die comprises a die plate, a die core, a sliding block guide rod, an inner die sliding block, a sliding block spring, a thimble and a sliding block binding block.
And the template comprises a male template and a female template.
The mold core is arranged in the template and comprises a male mold core and a female mold core, and injection molding holes are formed in the mold core.
The sliding block is arranged on the template, is connected with the sliding block in the mould, and is provided with a hole for extending a sliding block guide rod and a hole for extending a thimble; the sliding block is also provided with a sliding block spring, the sliding block spring is arranged below the sliding block and is used for generating spring force to enable the sliding block to be far away from the direction in the die.
Preferably, a wear-resistant block is arranged on the side, which is close to the slider binding block, of the slider when the slider is in die assembly.
The slide block guide rod is locked on the template.
The inner die sliding block is arranged on the die plate, is connected with the sliding block and is provided with a product forming groove; the inner die slide is used for driving the slide block connected with the inner die slide by the slide block guide rod and the slide block binding block when the inner die slide is used for closing the inner die.
The ejector pin, ejector pin one end is fixed in the mould benevolence, and it stretches into in locating the slider spring for ensure that the slider spring can not warp.
The sliding block beam block is a polygonal block body and is locked on the template to push the sliding block to the direction in the mould when the mould is closed.
[ description of the drawings ]
Fig. 1 is a cross-sectional view of the present invention in the mold closing.
Fig. 2 is a cross-sectional view of the invention in the open mode.
[ detailed description ] of the invention
The technical means adopted by the present invention and the effects thereof will be further described in detail below with reference to the embodiments of the present invention and the accompanying drawings.
Referring to fig. 1-2, the present invention provides a method comprising:
and molding the product A.
A template 100, the template 100 comprising a male template 110 and a female template 120.
The mold core 200 is disposed in the mold 100, and comprises a male mold core 210 and a female mold core 220, wherein the mold core 200 is provided with an injection hole 230.
The sliding block 300 is arranged on the male die plate 110, is connected with the inner die block 500, and is provided with a hole 310 for extending the sliding block guide rod 400 and a hole 320 for extending the ejector pin; the slide block 300 is further provided with a slide block spring 330, the slide block spring 330 is arranged below the slide block 300, and the slide block spring 330 is used for generating spring force to enable the slide block 300 to be far away from the in-mold direction; the side of the slide block 300, which is abutted against the slide block bundle block 700 when the slide block is closed, is provided with a wear-resisting block 340.
The slider guide 400 is locked to the master template 120.
The inner mold slide 500 is arranged on the male mold plate 110, is connected with the slide 300, and is provided with a product forming groove 510; the inner mold slide 500 is used for driving the slide 300 connected with the inner mold slide 500 by the slide guide rod 400 and the slide bundle block 700 when the mold is closed, so that the inner mold slide 500 is abutted into the mold.
The ejector pin 600, one end of the ejector pin 600 is fixed in the male mold core 210, and extends into the slider spring 330 to ensure that the slider spring 330 cannot deform.
The slider block 700 is a polygonal block, which is locked to the master template 120 to push the slider 300 in the mold during mold closing.
The invention has the benefits that the mechanism for preventing the deformation of the sliding block spring solves the problem of insufficient length by replacing the spring locating pin with the common thimble, so that the whole section of spring can be protected, the cost for purchasing the spring locating pin with the fixed specification is saved, the assembly is convenient, the mechanism can be widely applied to die designs with different requirements, and the mechanism is a stable and economic solution.
It should be noted that the technical principles of the present invention have been described above in connection with specific embodiments, which are only for the purpose of explaining the principles of the present invention and should not be construed as limiting the scope of the present invention in any way.
Other embodiments of the invention will be apparent to those skilled in the art from consideration of this specification without undue burden.
