Description
Technical field
The utility model relates to a kind of injection mold, especially a kind of mold for preventing thimble impaired with release link.
Background technique
Plastic products part injection mold includes upper plate and lower plate, and cope plate is connected on upper plate, is equipped in cope plate upper
Mould insert；Lower template is connected with by support in lower plate, is equipped with lower die insert in lower template, upper mold insert and lower die insert are being closed
Mould is the type chamber to form injection-molded item；The thimble of the double-layer structure to connect with driving mechanism is equipped between lower plate and lower template
Plate, thimble lower endcaps are clamped between two layers of ejector retainner plate, and thimble passes through lower template and hole and upper end position in lower die insert
At the type chamber；The spring for making ejector retainner plate return is equipped between ejector retainner plate and lower template, the top of spring is located at lower template
On hole in.Lower plate moves up under power mechanism drive, makes lower die insert and upper mold insert combination shape forming cavity, passes through stream
Road is to the intracavitary injecting material of type, and after product molding, lower plate, support, lower template, lower die insert, ejector retainner plate move down simultaneously, that is, open
Mould, then ejector retainner plate moves up under actuator drive, and spring is compressed, and thimble upper end ejects product, and after ejection, ejector retainner plate exists
Spring acts on lower return.Over time, spring will appear the situation or spring breaking down of elastic force deficiency, and ejector retainner plate cannot return in time
Position, thimble upper end is also in state is exposed, and when molding again, thimble upper end can be collided first, and then ejector retainner plate could return
Position, such thimble upper end can be damaged.
Summary of the invention
The purpose of the utility model is to provide a kind of structures can be first about to simply, when spring is ineffective by release link
Ejector retainner plate return, the mold for preventing thimble impaired with release link for not damaging thimble.
The mold for preventing thimble impaired with release link of the utility model, including upper plate and lower plate, connect on upper plate
There is cope plate, is equipped with upper mold insert in cope plate；Lower template is connected with by support in lower plate, lower die is equipped in lower template and inlays
Block, upper mold insert and lower die insert are the type chambers to form injection-molded item in molding；It is equipped with and driving between lower plate and lower template
The ejector retainner plate for the double-layer structure that mechanism connects, thimble lower endcaps are clamped between two layers of ejector retainner plate, and thimble passes through lower template under
Hole and upper end in mould insert are located at the type chamber；The bullet for making ejector retainner plate return is equipped between ejector retainner plate and lower template
Spring, the top of spring are located in the hole in lower template；Spring inner hole inserted with release link, lower template is inserted on release link top
On hole in and expose from the upper surface of lower template, the lower endcaps of release link are located in the groove below the ejector retainner plate on upper layer, reset
Gap L is formed between the lower endcaps of bar and the bottom surface of groove, elastic plastic is equipped in the ejector retainner plate of lower layer, elastic plastic passes through screw
It is connected on the ejector retainner plate of lower layer, the elastic plastic upper end acts against on the lower end surface of release link.
The mold for preventing thimble impaired with release link of the utility model, cannot if spring is ineffective when die sinking
Make ejector retainner plate return, release link is in upper under the action of elastic plastic, i.e. L is equal to zero, ensure that release link upper end is higher than top
The upper end of needle, release link upper end is first pressed down when molding, and ejector retainner plate restorable, thimble move down under the pressure of release link, effectively
The upper end for protecting thimble.Therefore the utility model is simple with structure, can pass through release link when spring is ineffective
First it is about to ejector retainner plate return, does not damage the advantages of thimble.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of specific embodiment of the present invention.
Specific embodiment
The mold for preventing thimble impaired with release link of the utility model as shown in Figure 1:, including upper plate 1 and lower plate 8,
It is connected with cope plate 2 on upper plate 1, is equipped with upper mold insert 3 in cope plate 2；
Lower template 5 is connected with by support 6 in lower plate 8, is equipped with lower die insert 4, upper mold insert 3 and lower die in lower template 5
Insert 4 is the type chamber to form injection-molded item 10 in molding；
The ejector retainner plate 7 of the double-layer structure to connect with driving mechanism, 9 lower endcaps of thimble are equipped between lower plate 8 and lower template 5
It is clamped between two layers of ejector retainner plate 7, hole and upper end of the thimble 9 across lower template 5 and in lower die insert 4 are located at the type chamber
Place；
The spring 11 for making 7 return of ejector retainner plate is equipped between ejector retainner plate 7 and lower template 5, the top of spring 11 is located at lower die
In hole on plate 5；
Spring 11 inner hole inserted with release link 12,12 top of release link is inserted into the hole in lower template 5 and from lower die
The upper surface of plate 5 exposes, and the lower endcaps of release link 12 are located in the groove 13 below the ejector retainner plate 7 on upper layer, the lower end of release link 12
Gap L is formed between cap and the bottom surface of groove 13, elastic plastic 14 is equipped in the ejector retainner plate 7 of lower layer, elastic plastic 14 passes through screw
15 are connected on the ejector retainner plate 7 of lower layer, and 14 upper end of elastic plastic acts against on the lower end surface of release link 12.
The mold for preventing thimble impaired with release link of the utility model, when die sinking, if spring 11 is ineffective, no
It can make 7 return of ejector retainner plate, release link 12 is in upper under the action of elastic plastic 14, i.e. L is equal to zero, ensure that in release link 12
End is higher than the upper end of thimble 9, and 12 upper end of release link is first pressed down when molding, 7 restorable of ejector retainner plate under the pressure of release link 12,
Thimble 9 moves down, and effectively protects the upper end of thimble 9.Therefore the utility model have structure it is simple, when spring is ineffective
When can first be about to ejector retainner plate return by release link, not damage the advantages of thimble.
