Abstract
The utility model discloses a kind of damage control die; including die ontology; the die ontology is provided with the thimble for being used for forming the die cavity of injecting products and abutted with the die cavity; also include thimble protective case; the thimble protective case is fixed on the lower section of the die cavity, and the thimble protective case is slidably matched with the thimble.The utility model adds thimble protective case so that thimble is not easy directly to be worn, and when thimble protective case weares and teares to a certain extent, thimble protective case is replaced, so that maintenance cost is reduced；The stuck risk of thimble is reduced, so as to avoid the damage of mould, production efficiency is improved.
Description
Technical field
The utility model belongs to injection mold field, especially a kind of damage control die.
Background technology
Existing injection mold is after the completion of injection, and because BMC is thermosetting plastics, mould temperature reaches 170
DEG C, during thimble ejection injecting products, because mold temperature is too high, there is stuck risk in thimble, and thimble can not take out when stuck；
When thimble is stuck, meeting mold damage results in greater loss again, and subsequent maintenance difficulty is big.
Utility model content
The purpose of this utility model be the defect for overcoming prior art there is provided a kind of damage control die, improve making for thimble
With the life-span, change convenient, improve production efficiency.
The utility model solves the technical scheme that prior art problem is used：Damage control die, including die ontology, it is described
Die ontology is provided with the thimble for being used for forming the die cavity of injecting products and abutted with the die cavity, in addition to thimble protective case,
The thimble protective case is fixed on the lower section of the die cavity, and the thimble protective case is slidably matched with the thimble.
Further, the thimble protective case is made of high speed steel material, with good wearability and heat resistance, is kept away
Exempt from the softening of thimble, improve the service life of thimble.
Further, the section of the thimble protective case is inverted " t " font.
Further, provided with protection hole, the outer wall of the thimble and the inwall in the protection hole in the thimble protective case
Coordinate, this fit system performance is stable, be less prone to sliding inclined and derailing phenomenon.The service life of thimble is improved,
Without often being repaired and being changed to thimble in production process, production efficiency is substantially increased, being produced into for workpiece is reduced
This.It is also more convenient that other thimble is broken replacing.
The beneficial effects of the utility model are：The utility model adds thimble protective case so that thimble is not easy directly
It is worn, when thimble protective case weares and teares to a certain extent, thimble protective case is replaced, so that maintenance cost drops
It is low；The stuck risk of thimble is reduced, so as to avoid the damage of mould, production efficiency is improved.
Brief description of the drawings
The utility model is described in further detail with reference to the accompanying drawings and examples.
Fig. 1 is structural representation of the present utility model.
In figure：1st, die ontology；2nd, die cavity；3rd, thimble；4th, thimble protective case；5th, hole is protected.
Embodiment
The utility model is described in further detail presently in connection with accompanying drawing.These accompanying drawings are simplified schematic diagram,
Only illustrate basic structure of the present utility model in a schematic way, therefore it only shows the composition relevant with the utility model.
Damage control die as shown in Figure 1, including die ontology 1, the die ontology 1, which is provided with, to be used to form injecting products
Die cavity 2 and the thimble 3 that is abutted with the die cavity 2, in addition to thimble protective case 4, the thimble protective case 4 is fixed on the type
The lower section of chamber 2, the thimble protective case 4 is slidably matched with the thimble 3.Provided with protection hole 5, institute in the thimble protective case 4
The outer wall of thimble 3 is stated with the inwall in the protection hole 5 to coordinate.
Specifically, the thimble protective case 4 is made of high speed steel material.
Specifically, the section of the thimble protective case 4 is inverted " t " font.
When mould is after the completion of injection, BMC is thermosetting plastics during ejection, and mould temperature is 170 DEG C.So on top
Because mold temperature height, thimble 3 have stuck risk when pin 3 ejects injecting products, increase thimble protective case 4 so that thimble 3 is not
Easily directly it is worn, when thimble protective case 4 weares and teares to a certain extent, is replaced as long as taking out thimble protective case 4,
Without damaging mould.
Specific case used herein is set forth to principle of the present utility model and embodiment, above example
Explanation be only intended to help and understand method of the present utility model and its core concept.It should be pointed out that for the art
For those of ordinary skill, on the premise of the utility model is not departed from, can also to the utility model carry out it is some improvement and
Modification, these are improved and modification is also fallen into the utility model scope of the claims.
