Specific embodiment
The utility model is further described with the following Examples.
A kind of mold being equipped with miniature mold core of the utility model, as illustrated in fig. 1 and 2, including lower template 1, profiled sheeting
2, miniature mold core 3, cope plate 4 and mode locking plate 5.As shown in Figure 1-3, the centre on the top of lower template 1 is provided with the first forming cavity 11,
The bottom of first forming cavity 11 offers 12 installing blinds 111 that can be inserted into miniature mold core 3, installing blind 111 respectively according to
A line 6 are divided to two rows side by side, and the diameter of installing blind 111 is 2mm.Convex block 51 is equipped with below mode locking plate 5.
As shown in fig. 7, miniature mold core 3 is multi-diameter shaft or cross section is circular cylinder, the forming part 33 of miniature mold core 3
Diameter be 2mm, the size of middle part 32 is 3mm, and the size of mounting portion 31 is 4mm.
As shown in Figure 1, Figure 2 and Figure 4, the centre of profiled sheeting 2 is provided with mounting groove, and the slot bottom of mounting groove is provided with the second forming cavity
21, second forming cavity 21 is located at the lower part of profiled sheeting 2, and corresponding with the first forming cavity 11 of lower template 1.First at
Type chamber 11 and the second forming cavity 21 surround the type chamber of shaped article jointly.
As shown in Figure 1, Figure 2, shown in Fig. 5 and Fig. 6, the top of the centre of cope plate 4 is provided with and 51 phase of convex block on mode locking plate 5
The avoiding hollow groove 41 matched, i.e. convex block 51 can be inserted in avoiding hollow groove 41, and think with avoiding hollow groove 41 chimeric.The slot bottom of avoiding hollow groove 41 is opened
The installation through-hole 411 that diameter equipped with 12 for the insertion of miniature mold core is 4mm, installation through-hole 411 and the installation in lower template
Blind hole 111 is corresponding one by one in the vertical direction.Installation through-hole 411 is stepped hole, the diameter on the ladder top 412 of stepped hole
For 4mm, the diameter of the mounting portion 31 of miniature mold core 3 is corresponded to, the diameter of the ladder lower part 413 of stepped hole is 3mm, is corresponded to micro-
The diameter of 3 middle part 32 of pattern core.4 central bottom of cope plate has the flange extended downwardly, and all installation through-holes 411 pass through
Flange is worn, the mounting groove of flange and profiled sheeting 2 matches.When cope plate 4 and profiled sheeting 2 assemble, flange is inserted into mounting groove.It will
All miniature mold cores 3 are inserted into installation through-hole 411, and the bottom of miniature mold core 3 passes through the peace that installation through-hole 411 is inserted into lower template 1
It fills in blind hole 111.Step between the mounting portion 31 and middle part 32 of miniature mold core 3 resists the rank in the stepped hole of cope plate 4
On ladder, the groove bottom of the avoiding hollow groove 11 on the upper surface and cope plate 4 of miniature mold core 3 is on the same horizontal plane.
What profiled sheeting 2 and the design of cope plate 4 can also be integrated by not preferred scheme, i.e., one is opened in the lower section of cope plate 4
A and identical slot of the second forming cavity 21, equally may be implemented the effect that this present embodiment is wanted, but be not easy to the processing of mold.
When molding, profiled sheeting 2 is covered in lower template 1, and the first forming cavity 11 and the second forming cavity 21 collectively form type chamber.Again
Cope plate 4 is covered, the flange on cope plate 4 is insert molded in the second forming cavity 21 in plate 2.Miniature mold core 3 is inserted one by one
Enter in the installation through-hole 411 on cope plate 4, the step between miniature 3 mounting portion 31 of mold core and middle part 32 resists installation through-hole
Ladder in 411.Then mode locking plate 5 is covered on cope plate 4, so that the convex block 51 on mode locking plate 5 is inserted into avoiding hollow groove 41, into
And squeezing miniature mold core 3 is installed in place it.
In the process of implementation, it does not need as miniature mold core 3 is squeezed into cope plate 4 using other tools in the prior art
In the installation through-hole 411 of only 2mm, but after cope plate 4 covers on profiled sheeting 2, it is inserted into miniature mold core 3, then cover lock
Template 5 squeezes miniature mold core 3 using the convex block 51 below mode locking plate 5, and miniature mold core 3, which is expressed to, needs position to be mounted.By
It is bigger than the diameter of the forming part 33 of miniature mold core 3 in the diameter of the installation through-hole 411 of cope plate 4, in can comparing for miniature mold core 3
It is easier in the installation through-hole 411 of insertion cope plate 4.Mounting portion 31 of the installation through-hole 411 of cope plate 4 and miniature mold core
Match, the diameter of the mounting portion 31 of miniature mold core 3 determines according to actual conditions, and then can correspondingly can adjust cope plate 4
The diameter of installation through-hole 411 guarantees to add so that the installation through-hole 411 of cope plate 4 may be adjusted to the size for being easier processing
Work precision.The middle part 32 for setting up miniature mold core is forming part 33 and miniature mold core 3 in order to preferably complete miniature mold core 3
The transition of mounting portion 31 dimensionally prevents the forming part 33 of miniature mold core 3 from differing too big with the size of mounting portion 31 and causing
The reduction of miniature 3 structural strength of mold core.In addition, be inserted into miniature mold core 3 and molding during but also miniature mold core 3 not
It easily snaps off.Not preferred scheme, the installation through-hole 411 on cope plate 4 do not use stepped hole, the use of diameter are directly the logical of 4mm
Hole also uses corresponding two sections of multi-diameter shafts in the design of miniature mold core 3, i.e., does not set the middle part 32 of miniature mold core, multi-diameter shaft
Mounting portion 31 be the diameter that is matched with the installation through-hole 41 of cope plate 4 be 4mm, the diameter of the forming part 33 of multi-diameter shaft is
2mm.When molding, miniature mold core 3 is inserted into installation through-hole 411, the installing blind 111 of miniature 3 bottom of mold core insertion lower template 1
In, then mode locking plate 5 is covered on cope plate 4, so that the convex block 51 on mode locking plate 5 is inserted into avoiding hollow groove 411, and then is squeezed micro-
Pattern core 3 is installed in place it.
In the present embodiment, the diameter of the forming part 33 of miniature mold core 3 is 2mm, the installation that cope plate 1 is 4mm using diameter
Through-hole 411.And the diameter of the mounting portion 31 of existing miniature mold core 3 is 2mm, the installation through-hole of corresponding cope plate 4 is also
2mm could and match the installation to realize miniature mold core 3 with miniature mold core 3 in this way, and this requires existing installation through-holes
Machining accuracy is relatively high, it is not easy to process.Opposite, the installation through-hole 411 that the diameter of the utility model is 4mm is easier can
With processing.Specifically in the process of implementation, installation through-hole 411 can be selected according to practical situation, due to the molding of miniature mold core 3
The diameter in portion 33 is all smaller, can generally select the installation through-hole 411 that diameter is bigger than the diameter of the forming part 33 of miniature mold core 3.
Due to the convenience for calculating and processing, generally upper mold can be designed using the multiple proportion of the diameter of the forming part 33 of miniature mold core 3
The installation through-hole 411 of plate 4.
The mold for being equipped with miniature mold core a kind of to the utility model above, is described in detail, used herein
Specific case is expounded the principles of the present invention and embodiment.The explanation of above example is only intended to help to manage
Solve the core concept of the utility model；At the same time, for those skilled in the art, based on the idea of the present invention,
There will be changes in specific embodiment and application range, in conclusion the content of the present specification should not be construed as to this reality
With novel limitation.
