Abstract
The present invention discloses the spring structure of a kind of mould slide block, this mould has slide block, is located at the template below described slide block, the die being located in described template, described spring structure includes: chute, and 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 side is held in described spring away from described die one end.Utilize the spring structure of the mould slide block of the present invention, owing to described spring is located in the chute of described template, be therefore no longer necessary to increase the size of slide block, and then without increasing the thickness of die, template, save the cost of mould；Owing to described chute position in described template is the most unrestricted, thus the installation site of described spring is more flexible；Owing to spring is arranged on slider bottom, thus without causing and Angle Pin, the interference in water route.
Description
[technical field]
The present invention relates to a kind of spring structure, particularly relate to the spring structure of a kind of mould slide block.
[background technology]
When producing the shell of electronic product, it will usually use plastic mould, and some mould is to product
May require that the when of molding that slide block is arrived in use, when using the mould die sinking of slide block, for anti-limited slip block return,
Generally can be designed with again spring.
Refer to the spring structure schematic diagram that Fig. 1, Fig. 1 are schematically shown as the mould slide block of prior art.Described mould
Have template 1, die 2, slide block 3, slide block enter son 4, Angle Pin 5, spring 6.Described slide block 3 is close
Die 2 one STH, 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, use said structure, 1 can be there is problems in that, need described slide block 3 to accomplish sufficiently large,
In order to be installed with described spring 6, in addition to the material of the described slide block of waste 3 itself, described die 2 is also required to phase
Should thicken, for having the mould of Mould kernel constraint block under slide block, the thickness of described die 2 is bigger, phase
Answer ground also can increase the thickness of template 1, so increase the cost of mould；2, the installation of described spring 6
Space is very limited, and must keep out on described die 2 one end；If 3 springs 6 are long, the most very
Easily interfere with described Angle Pin 5 or water route.
In view of this, it is necessary to develop the spring structure of a kind of mould slide block, to solve the problems referred to above in fact.
[summary of the invention]
Therefore, it is an object of the invention to provide the spring structure of a kind of mould slide block, solve owing to arranging spring
Cause the die assembly such as slide block to thicken, the installing space of spring is limited and between spring and other die assembly
The problem interfered.
In order to achieve the above object, the spring structure of mould slide block that the present invention provides, this mould have slide block,
Being located at the template below described slide block, the die being located in described template, described spring structure includes:
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 side is held in described spring away from described mould
Core one end.
Optionally, described chute is U-type groove.
Optionally, described slide block is provided with slide block bundle block away from described die side.
Optionally, described slide block is provided with slide block near described die side and enters son.
Compared to prior art, utilize the spring structure of the mould slide block of the present invention, owing to described spring is located at
In the chute of described template, therefore it is no longer necessary to increase the size of slide block, and then without increasing die, template
Thickness, save mould cost；Owing to described chute position in described template is the most unrestricted,
Thus the installation site of described spring is more flexible；Owing to spring is arranged on slider bottom, thus without cause with
Angle Pin, the interference in water route.
[accompanying drawing explanation]
Fig. 1 is schematically shown as the spring structure schematic diagram of the mould slide block of prior art.
The matched moulds status architecture of spring structure one preferred embodiment that Fig. 2 is schematically shown as the mould slide block of the present invention shows
It is intended to.
The die opening state structure of spring structure one preferred embodiment that Fig. 3 is schematically shown as the mould slide block of the present invention is shown
It is intended to.
[detailed description of the invention]
Refer to the matched moulds of spring structure one preferred embodiment that Fig. 2, Fig. 2 are schematically shown as the mould slide block of the present invention
Status architecture schematic diagram.
In order to achieve the above object, the spring structure of the mould slide block that the present invention provides, this mould has slide block
10, the die 30 be located at the template 20 below described slide block 10, being located in described template 20, described spring
Structure includes:
Chute 40, it is located in described template 20, and described chute 40 is towards a side opening of described slide block 10；
Spring 50, it is located in described chute 40, and it is close that described spring 50 one end is held in described chute 40
Described die 30 one end；
Block 60, it is fixed on bottom described slide block 10, and described block 60 side is held in described spring 50
Away from described die 30 one end.
Wherein, described chute 40 is U-type groove, and convenient making in described template 20, it is beneficial to described bullet
Spring 50 is placed.
Wherein, described slide block 10 is provided with slide block bundle block 70 away from described die 30 side；Described slide block 10 leans on
Nearly described die 30 side is provided with slide block and enters son 80.
Wherein, in described slide block 10, also it is inserted with Angle Pin 90, in order to drive described slide block 10 to slide.
The opening of spring structure one preferred embodiment of the mould slide block of the present invention it is schematically shown as referring again to Fig. 3, Fig. 3
Mould status architecture schematic diagram.
When die sinking, described Angle Pin 90 drives described slide block 10 to slide, and described block 60 is with described slide block
10 slide, and described spring 50 discharges, and then prevents described slide block 10 return.
Visible, utilize the spring structure of the mould slide block of the present invention, owing to described template is located at by described spring 50
In the chute 40 of 20, therefore it is no longer necessary to increase the size of slide block 10, and then without increasing die 30, mould
The thickness of plate 20, saves the cost of mould；Owing to the described chute 40 position in described template 20 is flexible
Unrestricted, thus the installation site of described spring 50 is more flexible；Owing to spring 50 is arranged on slide block 10 end
Portion, thus without causing and Angle Pin 90, the interference in water route.
