Four are opened up in criss-cross fluting, the cavity plate top opens up centre hole, and the cavity plate lower part opens up accommodating hole, the thimble
Hole is connected to the accommodating hole.
Preferably, being additionally provided with square iron between the bottom plate and lower template.
Preferably, the thimble panel is fixed on Ejector Retainer Plate, the Ejector Retainer Plate is fixed on the bottom plate.
Preferably, the Ejector Retainer Plate is connect with the top rod of external injection molding machine.
Preferably, being fixed with thimble on the panel.
Preferably, the outer diameter of the thimble is less than the internal diameter of the centre hole.
Preferably, the top internal diameter of the punch-pin is less than described when the top of the punch-pin is set in the accommodating hole
The outer diameter of thimble.
Preferably, the top internal diameter of the punch-pin is greater than institute when be not inserted into the accommodating hole at the top of the punch-pin
State the outer diameter of thimble.
A kind of stroke protecting device of mold provided by the utility model, the beneficial effect is that: by setting cavity plate and
Punch-pin, it can be ensured that when not having return, upper mold can not be molded thimble panel, prevent thimble from hitting mode.

Specific embodiment
To further illustrate each embodiment, the utility model is provided with attached drawing.These attached drawings are in the utility model discloses
A part of appearance mainly to illustrate embodiment, and can cooperate the associated description of specification former come the running for explaining embodiment
Reason.Cooperation refers to these contents, and those of ordinary skill in the art will be understood that other possible embodiments and sheet are practical new
The advantages of type.Component in figure is not necessarily to scale, and similar component symbol is conventionally used to indicate similar component.
Now in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figure 1, 2, the stroke protecting device of mold provided in this embodiment, mold include panel 1, bottom plate 2, upper mold
Plate 3 and lower template 4 are fixed with thimble 5 on panel 1, and stroke protecting device is mounted between bottom plate 2 and lower template 4,2 He of bottom plate
Square iron 6 is additionally provided between lower template 4, stroke protecting device includes cavity plate 7 and punch-pin 8, and the lower part of lower template 4 is arranged in cavity plate 7,
Punch-pin 8 is arranged on thimble panel 9, and thimble panel 9 is fixed on Ejector Retainer Plate 10, and Ejector Retainer Plate 10 is fixed on a base plate 2, top
Needle bottom plate 10 is connect with the top rod 11 of external injection molding machine.
As shown in figure 3, punch-pin 8 is in cylindrical body, the top of punch-pin 8 opens up four in criss-cross fluting 12,7 top of cavity plate
Centre hole 71 is opened up, 7 lower part of cavity plate opens up accommodating hole 72, centre hole 71 and accommodating hole 72.5 outer diameter of thimble is less than centre hole 71
Diameter.Accommodating hole 72 is set at the top of punch-pin 8,8 top internal diameter of punch-pin is less than 5 outer diameter of thimble.The top of punch-pin 8 is not inserted into accommodating hole 72
When interior, the top internal diameter of punch-pin 8 is greater than the outer diameter of thimble 5.
As shown in figure 4, the outer diameter of thimble is 4mm in this implementation, and when the top of punch-pin 8 is not inserted into accommodating hole 72, punch-pin
8 top internal diameter is 4.39mm, and the outer wall at the top of punch-pin 8 and the angle of vertical line are 0 °, i.e. the shape of the return of thimble panel 9
