Specific embodiment
Following will be combined with the drawings in the embodiments of the present invention, and technical solution in the embodiment of the present invention carries out clear, complete
Site preparation description, it is clear that described embodiments are only a part of the embodiments of the present invention, instead of all the embodiments.It is based on
Embodiment in the present invention, it is obtained by those of ordinary skill in the art without making creative efforts every other
Embodiment shall fall within the protection scope of the present invention:
As depicted in figs. 1 and 2, the present invention provides a kind of mold with fracture header structure, including upper mold 1, lower die 2 and picks up
Mechanism is taken, is set in the lower die 2 there are two foot mould 21, top plate 22 is equipped between described two foot moulds 21, the mechanism for picking is set
It sets on top plate 22；There are upper cores 11 in the upper mold 1, there is lower mode 23, the upper cores 11 are under in the lower die 2
The injection molding channel 4 that mode 23 is formed with the type chamber 3 for being used to form injecting products with merging and is used to form material head, the mold packet
It includes for being cut in the upper cores 11 and the lower mode 23 disengaging by what the injecting products and the material head were cut off
Disconnected component 5, the cutting section 5 are fixed on the lower mode 23, and at least part of cutting section 5 is on described
Mode 11 and the lower mode 23 are located in the upper cores 11 when cooperating, and the mechanism for picking includes corresponding with injecting products
First pickup unit 6 and the second pickup unit 7 corresponding with material head.
After the completion of injecting products injection molding, pass through the cutting section 5 that the injecting products and the material head can be cut off
With on mechanism for picking the first pickup unit 6 and the cooperation of the second pickup unit 7 to the injecting products property cut after demoulding.
The cutting section 5 is close in first pickup unit 6 and is arranged, and the cutting section 5 is located at described the first ten
The inside of unit 6 is taken, and the outside of the cutting section 5 is bonded with the inside of first pickup unit 6, described the first ten
Taking single 6 yuan can move up and down along the first pickup unit 6 and the binding face of cutting section.
Cutting section 5 separates type chamber 3 with injection molding channel 4 after the mold die sinking, and then material head and injecting products are divided
From since first pickup unit 6 and the cutting section 5 fit together, it can be ensured that the material on cutting injecting products
When head, cutting effect is good, and material head can disposably be cut off, and the section of injecting products is smooth, be not deformed.
In another embodiment, the cutting section 5 is L shape, and the lower end of the cutting section 5 has stage portion 50 simultaneously
Fixedly cooperate in lower mode 23, enhance the stability of the cutting section 5, it can be ensured that top plate 22 picks up list in promotion first
Member 6 and the second pickup unit 7 push the cutting section 5 when product not shift.
There is the cutting section 5 as shown in Figure 2 one to be used for the recirculation hole 51 that injection molding channel 4 is communicated with type chamber 3, described
Recirculation hole 51 be it is horn-like, the larger diameter end of the recirculation hole 51 is located at 4 side of injection molding channel, and smaller diameter end is located at type chamber 3
Side, the smaller diameter end edge of the recirculation hole 51 are equipped with the cutting edge of a knife 510, and the cutting section 5 is led to when trimming material head
The cutting edge of a knife 510 crossed on recirculation hole 51 can effectively increase the efficiency of material head on trimming injecting products.
Again as shown in figures 1 and 3, the mold injection carries out injecting products into glue mode for side, and described first picks up list
Member 6 is fitted on the side of L shape cutting section 5, also, first pickup unit 6 can along the first pickup unit 6 with cut
The binding face of disconnected component 5 moves up and down, the cutting section 5 set there are two and it is symmetrical along the central axes of the second pickup unit 7
Setting, the first pickup unit 6 being bonded with the cutting section 5 also are provided with two, and the type chamber 3 for injecting products is two,
The injection molding channel 4 is located among two type chambers 3 and is connected to the type chamber 3 of two sides, and described two cutting section 5 are located at type
The connectivity part of chamber 3 and injection molding channel 4, injecting glue material when injection molding pass through recirculation hole 51 in the cutting section 5 out of injection molding channel 4
Into type chamber 3.After the completion of injection molding, the product in injection molding channel 4 and type chamber 3 is all had been cured, and when being demoulded, passes through top plate
24 eject two the first pickup units 6 and the second pickup unit 7, two the first pickup units 6 simultaneously pushes up two type chambers 3
The injecting products of completion are inside molded, while the second pickup unit 7 can also eject injection molding channel 4, have ejected first in top plate 24
During pickup unit 6 and the second pickup unit 7, material head is all ejected in the injecting products and injection molding channel 4 in type chamber 3,
Since cutting section 5 is fixed in lower mode 23, under the cutting edge of a knife 510 of recirculation hole 51 acts in cutting section 5, connect originally
The injecting products and material head being connected together are cut off.Therefore, the injecting products obtained after demoulding are the notes that material head has been trimmed to about
Molding product does not need to increase the process manually trimmed, improves production efficiency.
For convenience of explanation and appended claims are accurately defined, term " on ", "lower", "inner" and "outside" be used to refer to
The position of these shown features describes the feature of exemplary implementation scheme in attached drawing.
Specific embodiment is applied in the present invention, and principle and implementation of the present invention are described, above embodiments
Explanation be merely used to help understand method and its core concept of the invention；At the same time, for those skilled in the art,
According to the thought of the present invention, there will be changes in the specific implementation manner and application range, in conclusion in this specification
Appearance should not be construed as limiting the invention.
