To achieve the above object, the utility model provides following technical scheme：
There is provided a kind of mouth of a river and injection mold that product is automatically separated, including the mold of mutual cooperation and lower mould；
The mold includes upper cores, and the upper cores are provided with upper mould product glue position and upper mould mouth of a river glue position；
The lower mould includes lower die, and the lower die is provided with lower mould product glue position and lower mould mouth of a river glue position；
The lower mould product glue position is connected by mould conical rubber position with the lower mould mouth of a river glue position, or the lower mould product
Glue position is connected by the mould conical rubber position with the upper mould mouth of a river glue position, or the upper mould product glue position is with passing through the mould
Conical rubber position is connected with the upper mould mouth of a river glue position, or the upper mould product glue position by the conical rubber position even with it is described under
Mould product glue position is connected, and the taper top of the mould conical rubber position is connected with the product glue position；
The lower mould mouth of a river glue position is connected with back-off slag well, and the lower mould product glue position apical grafting has thimble, the back-off
Slag well apical grafting has delay thimble, and the thimble is connected with ejector retainner plate；
The upper end size of the back-off slag well is smaller 2 ~ 4mn than its bottom size, the lower end of the back-off slag well
Portion is convex along glue position.
Preferably, the upper end size of the back-off slag well is smaller 3mm than its bottom size.
Preferably, the delay thimble includes ejection post and delay post, the column diameter of the ejection post and the delay
The column diameter of post is identical.
The beneficial effects of the utility model：
The injection mold that a kind of mouth of a river of the present utility model and product are automatically separated, the mould are set in lower mould mouth of a river glue position
Back-off slag well, and connect delay thimble, and product glue position and water with back-off slag well in lower mould mouth of a river glue position connection thimble
Enter glue point by taper between chewing-gum position to connect, during application, first open mould, thimble elder generation ejecting product, and back-off slag well is drawn
The firmly mouth of a river, the top power of thimble produce shearing force each other with the pulling force of back-off slag well, and this cut by so that product and the mouth of a river point
From finally, delay thimble ejects the mouth of a river by force again, that is, realizes that product and the mouth of a river are completely separated.Compared with prior art, the mould
The ejecting force and delay thimble delayed goring for only needing the pulling force, thimble of back-off can quickly and accurately separate product and the mouth of a river,
The labyrinth and program needed for cutting knife are avoided, and then improves separative efficiency and saves manufacturing cost；Also, back-off is cold
The upper end of material well is only smaller 2 ~ 4mm than its bottom and is provided with the glue position on convex edge, not only ensure that back-off slag well to water
The pulling force of mouth, it is ensured that the material of back-off slag well can be ejected smoothly.

Embodiment
The utility model is described in detail below in conjunction with specific embodiment and accompanying drawing.
The injection mold that a kind of mouth of a river and product in the present embodiment are automatically separated, as shown in Figures 1 to 4, including phase interworking
The mold of conjunction and lower mould；The mold includes upper cores 1, and upper cores 1 include the upper mould product glue on injecting products top
Position 11 and the upper mould mouth of a river glue position 12 on injection moulding regrinding top；
The lower mould includes lower die 2, and lower die 2 includes mould product glue position 21 and the injection moulding regrinding of injecting products bottom
The lower mould mouth of a river glue position 22 of bottom, lower mould product glue position 21 are connected with lower mould mouth of a river glue position 22 by lower mould conical rubber position 7.
Upper mould product glue position 11 is connected with upper mould mouth of a river glue position 12 by mould conical rubber position 7, or lower mould product glue position 21
It is connected with lower mould mouth of a river glue position 22 by mould conical rubber position 7, sizing material is not only saved in conical rubber position 7, and is beneficial to product and the mouth of a river
Quick separating, or lower mould product glue position 21 and upper mould product glue position 11 are connected by mould conical rubber position 7, and lower mould mouth of a river glue position
22 and upper mould mouth of a river glue position 12 connected by mould conical rubber position 7, sizing material is not only saved in conical rubber position 7, and is beneficial to product and water
Mouth quick separating.Lower mould mouth of a river glue position 21 is connected with back-off slag well 3, and the back-off resistance of back-off slag well 3 produces to regrinding-material
Pulling force, and the lower apical grafting of mould product glue position 21 has thimble 4, the apical grafting of back-off slag well 3 has delay thimble 5, and thimble 4 is connected with ejector retainner plate
6, delay thimble 5 be located at the side of ejector retainner plate 6, during application, first molds, 4 first ejecting product of thimble, and back-off slag well 3
Detain resistance and pulling force, product ejection mouth are produced to regrinding-material, delay thimble 5 ejects the mouth of a river again, i.e. back-off slag well 3 is to the mouth of a river
The ejecting force of pulling force and thimble 4 forms shearing force, so that product and mouth of a river quick separating, wherein, conical rubber position is more conducive to
The mouth of a river and product quick separating.
The upper end size of back-off slag well 3 is smaller 2 ~ 4mn than its bottom size, preferably 3mm so that back-off slag well
Resistance can not only be produced, at the same be also prevented from back-off resistance it is too big and the problem of be unfavorable for ejection, the bottom of back-off slag well 3
It is outer convex edge glue position 8, the ledge structure is simple and can aid in increasing the resistance of back-off.
In the present embodiment, delay thimble 5 includes the ejection post 51 for ejecting the mouth of a river and ejects prolonging for post 51 for jacking up
When post 52, wherein, eject post 51 column diameter with delay post 52 column diameter it is identical, overcome the post that is delayed in the prior art
52 diameter is bigger than the diameter for ejecting post 53 so that the problem of waste of materials.
In the present embodiment, the conical top of mould conical rubber position 7 is connected with mould product glue position, conical top and product glue position
Connection to be easy to taper sizing material and product glue position quickly, efficiently separate, so as to ensure that the quality of product.
