" stripping result is good, and reliability is high, effectively prevent and pulls the white phenomenon of plastic product and top." but fail to solve well entirely
Product it is most of in sliding block in the case of will not follow the use problem that big sliding block is walked in the demoulding.
The content of the invention
The main inventive purpose of the present invention, be to provide it is a kind of solve whole product it is most of in sliding block in the case of how
The problem of sliding block is walked will not be followed in the demoulding.
Technical scheme used in the present invention is：Band Dan Kuai mechanisms in a kind of sliding block, including sliding block base and sliding block.Sliding block exists
The boudary portion of plastic products die cavity, which is provided with some cavitys, the cavity, is provided with spring and bullet block, and wherein spring is located at cavity
Bottom and be connected with the bottom of chamber of cavity, bullet block positioned at cavity top and lower end be connected with the upper end of spring.
During normal process product, spring is pressurized, and bullet block is located in cavity.After product is machined, when sliding block is removed, bullet
Bullet block is ejected cavity by spring, so as to prevent product from following sliding block to walk, in favor of being normally carried out for processing.
Preferably, the spring is helical spring.This preferred scheme, simple in construction, processing and manufacturing is easy.
Preferably, when bullet block is not affected by pressure, the lower surface of bullet block is located in cavity, the upper surface projection of bullet block is recessed
Outside chamber；Bullet block is when being under pressure, and the upper surface of bullet block can be withdrawn into cavity.This preferred scheme, rational in infrastructure, product is closed
Lattice rate is high.
Preferably, also including connecting rod, the upper end of connecting rod and bullet block are movably connected；The lower end of connecting rod is provided with spiral shell
Line, the bottom of chamber of the cavity is provided with the screwed hole with the threaded adapter of connecting rod lower end, the lower end of connecting rod and screwed hole screw thread
Connection.Here the upper end of connecting rod and bullet block are movably connected, and refer to that bullet block can be movable within the specific limits, but not and even
The upper end of extension bar is separated.This preferred scheme, it is simple in construction, it is high using reliability.
Preferably, the upper end of cavity is the die cavity being adapted to bullet block.When bullet block is fallen completely within cavity, bullet block it is upper
The upper end of end face and cavity is flushed, and the lower surface of bullet block is supported on the bottom surface of die cavity.This preferred scheme, it is simple in construction, favorably
In improve spring service life and ensure the quality of product.
In summary, the beneficial effects of the invention are as follows：Block structure is played by set activity on sliding block, can effectively be prevented
Only product follows the problem of sliding block is walked, so as to be conducive to improving the yields of product.The present invention has simple in construction, processing and manufacturing
Easy advantage.

Embodiment
Below by embodiment, and with reference to accompanying drawing, technical scheme is described in further detail.
As shown in Figure 1, Figure 2 and Figure 3, the present invention includes sliding block base 1 and sliding block 2.Sliding block 2 is in the die cavity of plastic products 3
Boudary portion, which is provided with cavity 2.1, the cavity 2.1, is provided with spring 4 and bullet block 5, and wherein spring 4 is located at the bottom of cavity 2.1
And be connected with the bottom of chamber of cavity 2.1, the top and lower end that bullet block 5 is located at cavity 2.1 are connected with the upper end of spring 4.Preferably,
The spring 4 is helical spring.In use, when bullet block 5 is not affected by pressure, the lower surface of bullet block 5 is located in cavity 2.1, bullet
The upper surface projection of block 5 is outside cavity 2.1；Bullet block 5 is when being under pressure, and the upper surface of bullet block 5 can be withdrawn into cavity 2.1
It is interior.That is, when the good rear slider of product manufacturing is removed, the pressure that bullet block 5 is subject to reduces, bullet block 5 is acted in the ejection of spring 4
Under upper surface projection outside cavity 2.1 so that prevent product adhere sliding block and cause the damage of product and the removal of sliding block.
Preferably, present invention additionally comprises the connecting rod having not shown in figure, the upper end of connecting rod and the activity phase of bullet block 5
Even；The lower end of connecting rod is provided with fine thread, and correspondingly the bottom of chamber of the cavity 2.1 is provided with the threaded adapter with connecting rod lower end
Fine thread hole 2.2, the lower end and fine thread hole 2.2 of connecting rod are threadedly coupled.In addition, the upper end of cavity is suitable with bullet block
The die cavity matched somebody with somebody.When bullet block is fallen completely within cavity, the upper surface of bullet block and the upper end of cavity are flushed, the lower surface support of bullet block
On the bottom surface of die cavity.
Specific embodiment described above is only the present invention preferably embodiment, not limits the specific of the present invention with this
Practical range.In fact, some equivalent changes can also be made according to shape of the present invention, structure and purpose of design.
