Description
Technical field
The utility model belongs to mould applications, especially a kind of bullet block for penetrating pushing method for double-colored inverted mold first
Structure.
Background technology
It is developed rapidly at this stage in mould industry, is attempted to create relatively reliable, significantly more efficient mould structure, energy
It enough realizes the smooth demoulding of product, while reducing the defect of product to greatest extent.Bullet block be in mold design frequency of use compared with
High structure is especially that by the molding bullet block structure of double-colored upside-down mounting.The use of bullet block so that the structure of mold is more
Abundant, mold more tends to high-endization.
Double-colored inverted mold face product stick cover half, there are two or more pieces bullet block lines and spring failure to cause to push up for product
The problems such as block is stuck, to affect product quality.
Utility model content
For solve the prior art there are product stick cover half, there are two or more pieces bullet block lines and spring failure to cause for product
The stuck defect of jacking block, the utility model provide a kind of bullet block structure for penetrating pushing method for double-colored inverted mold first, come
Realize the fixation of pcb board, it is simple in structure, easy for installation.
To achieve the above object, the utility model uses following technical proposals：
A kind of bullet block structure for penetrating pushing method for double-colored inverted mold first, it includes playing block body, stop screw
And spring, it plays in block body end and is provided with spring, play and be provided with stop screw in the guide groove of block body；
It is inclined-plane that block body top boss, which is played, with mavable module core mating surface, and drafting angle is 3 ° -8 °；
The central shaft angle for playing block body side and its guide groove is 3 °；
It is to face directly that block body end, which is played, with fixed mold core mating surface.
Above-mentioned bullet block body top boss is inclined-plane with mavable module core mating surface, and drafting angle is 3 ° -8 °, to realize in mould
Tool die sinking moment plays the role of positioning, and prevents from loosening when playing block body ejection and leading to generate two or more pieces bullet block line on product,
Inclined-plane can guarantee that block body is played in the case of spring failure follows mavable module core to walk, and plays block body top boss and mavable module core simultaneously
The drafting angle of mating surface is smaller, and frictional force is bigger, plays block body top boss and mavable module core package power is bigger, in mold clamping
When play the guiding role.The central shaft angle of above-mentioned bullet block body side and its guide groove is 3 °, to ensure to play block body energy
Smoothly movement.It is to face directly to play block body end, i.e., drafting angle is 0 °, and block body and fixed mold core positioning action are played to realize,
It prevents from playing block body rotation and causing to generate a plurality of bullet block line on product, even results in and play block body and fixed mold core damage.It is above-mentioned
It is provided with stop screw in guide groove, ensures the displacement distance for playing block body.Above-mentioned spring is driving bullet when mold molds
Block body moves, and to drive product to move, achievees the purpose that product follows mavable module core to move.
Further, the stroke for playing block body is 5mm-10mm.
The stroke of above-mentioned bullet block body is 5mm-10mm, and bullet block body can be in time while to ensure that product can be ejected smoothly
It resets.
Further, it is 10mm-15mm to play block body top boss with mavable module core mating surface height.
Advantageous effect：
1. the utility model is suitable for double-colored flip injection mold, in die sinking, by spring force so that die sinking moment bullet
Block body follows mavable module core to move with product, and reducing on the glutinous cover half of product and product has the defects of a plurality of bullet block line, to
Improve injecting products quality.
2. the utility model is coordinated by bullet block body top boss and mavable module core, guiding can be played in molding and is determined
Position effect, improves the service life of mold.

Bullet block structural diagram when Fig. 2 is the mold clamping of one embodiment of the utility model；
Fig. 3 is to play block structural diagram after the mold of one embodiment of the utility model molds；
In figure：1- bullets block body, 2- stop screws, 3- springs, 4- products, 5- mavable module cores, 6- fixed mold cores.
Specific implementation mode
The utility model is further illustrated with reference to the accompanying drawings and examples.
The present embodiment discloses a kind of bullet block structure for penetrating pushing method for double-colored inverted mold first, as shown in Figure 1, bullet
It is provided with spring 3 in 1 end of block body, plays in the guide groove of block body 1 and is provided with stop screw 2；
It is inclined-plane that 1 top boss of block body, which is played, with 5 mating surface of mavable module core, and drafting angle is 3 ° -8 °, is highly 10mm-
15mm；
The central shaft angle for playing 1 side of block body and its guide groove is 3 °；
It is to face directly that 1 end of block body, which is played, with 6 mating surface of fixed mold core；
The stroke for playing block body 1 is 5mm-10mm.
The operation principle of the utility model is：
1. molding moment
As shown in figure 3, playing block body 1 due to the spring force by spring 3 in die sinking moment and pushing product 4 along guide groove
Movement plays die sinking action movement of the 1 top boss of block body with 5 mating surface of mavable module core with mold, and then prevents from playing block body 1
It shakes on product 4, generates two or more pieces bullet block line.When spring 2 fails, 1 top boss of bullet block body is matched with mavable module core 5
Conjunction face also can guarantee that play block body 1 follows mavable module core 5 to move in die sinking moment.When encountering stop screw 2, bullet block body 1 stops
Movement, to ensure reliability of structure.
2. matched moulds stage
As shown in Fig. 2, when mold clamping, molding of the 1 top boss of block body with 5 mating surface of mavable module core with mold is played
Action movement plays guiding and positioning action when mating surface touches mavable module core 5.It is to face directly to play 1 end of block body, is used
To realize the positioning action for playing block body 1 and fixed mold core 6, cause to generate on product 4 a plurality of to prevent from playing the rotation of block body 1
Bullet block line even results in and plays block body 1 and the damage of fixed mold core 6.
As shown in figure 3, making 1 homing of bullet block body under mode locking force effect at this time, entire mold also returns to molding
State is as shown in Fig. 2, prepare to start injection moulding process next time.
Limitation to scope of protection of the utility model, those skilled in the art should understand that, in the skill of the utility model
On the basis of art scheme, the various modifications or variations that can be made by those skilled in the art with little creative work still exists
Within the scope of protection of the utility model.
