Abstract
The invention discloses a spring structure of a die slider, wherein a die is provided with the slider, a template arranged under the slider, and a die cavity formed in the template; and the spring structure comprises a sliding groove formed in the template, a spring arranged in the sliding groove and a stop block fixed at the bottom of the slider, the side of the sliding groove toward the slider is open; one end of the spring is propped against one end of the sliding groove in the vicinity of the die cavity; and one side of the stop block is propped against one end of the spring far away from the die cavity. The spring structure of the die slider provided by the invention is characterized in that the size of the slider does not need to be increased because the spring is arranged in the sliding groove of the template; therefore, the thickness of the die cavity and the template does not need to be increased, and the cost of the die is saved; the position of the sliding groove on the template is flexible and not limited, so that the mounting position of the spring is quite flexible; and as the spring is arranged on the bottom of the slider, interferences with an inclined guide column and a water route cannot be caused.
Description
[technical field]
The present invention relates to a kind of spring structure, particularly relate to a kind of spring structure of mould slide block.
[background technology]
In the time producing the shell of electronic product, conventionally can use plastic mould, and some mould can need to use slide block in to formed product, in the time using the mould die sinking of slide block, for anti-limited slip block return, conventionally can be designed with again spring.
Refer to Fig. 1, Fig. 1 illustrates the spring structure schematic diagram into the mould slide block of prior art.Described mould has template 1, die 2, slide block 3, slide block and enters son 4, Angle Pin 5, spring 6.Described slide block 3 is near die 2 one STHs, and one end of described spring 6 is located in the described hole of described slide block 3, and another section is kept out on described die 2.
But, adopt said structure, can there is following problem: 1, described slide block 3 need to be accomplished enough large, in order to be installed with described spring 6, except wasting the material of described slide block 3 own, described die 2 also needs corresponding thickening, for the mould under slide block with Mould kernel constraint block, the thickness of described die 2 is larger, correspondingly also can increase the thickness of template 1, so increases the cost of mould; 2, the installing space of described spring 6 is very limited, and must keep out on described die 2 one end; If 3 springs 6 are long, be easy to interfere with described Angle Pin 5 or water route.
In view of this, be necessary to develop in fact a kind of spring structure of mould slide block, to address the above problem.
[summary of the invention]
Therefore, the object of this invention is to provide a kind of spring structure of mould slide block, solve due to spring being set and cause the problem of interfering between the installing space of the thickening of the die assembly such as slide block, spring limited and spring and other die assembly.
In order to achieve the above object, the spring structure of mould slide block provided by the invention, this mould has slide block, is located at the template of described slide block below, is located at the die in described template, and described spring structure comprises:
Chute, it is located in described template, and described chute is towards a side opening of described slide block;
Spring, it is located in described chute, and described spring one end is held in described chute near described die one end;
Block, it is fixed on described slider bottom, and described block one side is held in described spring away from described die one end.
Optionally, described chute is U-shaped groove.
Optionally, described slide block is provided with slide block bundle piece away from described die one side.
Optionally, described slide block is provided with slide block near described die one side and enters son.
Compared to prior art, utilize the spring structure of mould slide block of the present invention, because described spring is located in the chute of described template, therefore no longer need to increase the size of slide block, and then without the thickness that increases die, template, save the cost of mould; Because the position of described chute in described template is unrestricted flexibly, thereby the installation site of described spring is more flexible; Because spring is arranged on slider bottom, therefore can not cause the interference with Angle Pin, water route.
[accompanying drawing explanation]
Fig. 1 illustrates the spring structure schematic diagram into the mould slide block of prior art.
Fig. 2 illustrates the matched moulds status architecture schematic diagram into spring structure one preferred embodiment of mould slide block of the present invention.
Fig. 3 illustrates the die opening state structural representation into spring structure one preferred embodiment of mould slide block of the present invention.
[specific embodiment]
Refer to Fig. 2, Fig. 2 illustrates the matched moulds status architecture schematic diagram into spring structure one preferred embodiment of mould slide block of the present invention.
In order to achieve the above object, the spring structure of mould slide block provided by the invention, this mould has slide block 10, is located at the template 20 of described slide block 10 belows, is located at the die 30 in described template 20, and described spring structure comprises:
Wherein, described chute 40 is U-shaped groove, convenient making in described template 20, and it is beneficial to described spring 50 and places.
Wherein, described slide block 10 is provided with slide block bundle piece 70 away from described die 30 1 sides; Described slide block 10 is provided with slide block near described die 30 1 sides and enters son 80.
Wherein, in described slide block 10, be also inserted with Angle Pin 90, in order to drive described slide block 10 to slide.
Referring again to Fig. 3, Fig. 3 illustrates the die opening state structural representation into spring structure one preferred embodiment of mould slide block of the present invention.
In the time of die sinking, described Angle Pin 90 drives described slide block 10 to slide, and described block 60 slides with described slide block 10, and described spring 50 discharges, and then prevents described slide block 10 returns.
Visible, utilize the spring structure of mould slide block of the present invention, because described spring 50 is located in the chute 40 of described template 20, therefore no longer need to increase the size of slide block 10, and then without the thickness that increases die 30, template 20, save the cost of mould; Because the position of described chute 40 in described template 20 is unrestricted flexibly, thereby the installation site of described spring 50 is more flexible; Because spring 50 is arranged on slide block 10 bottoms, therefore can not cause the interference with Angle Pin 90, water route.
