Abstract
The present invention provides a kind of production method of the low-pressure injection mold using silica gel sliding block, including：Drafting original paper map file, revision mold prototype map file, making low pressure mold prototype, drafting back-off structure map file, making silica gel sliding block, unitary mould making, low pressure die perfusion and product are completed.The production method of low-pressure injection mold provided by the invention using silica gel sliding block, by the way that the back-off structure of product to be formed is carried out separately formed support silica gel sliding block, and when making prototype, it will be in the size merging prototype of silica gel sliding block so that after making prototype mold, silica gel sliding block can be directly placed in prototype mold, carry out unified perfusion, and after prototype mold die sinking, silica gel sliding block is removed, finished product is obtained.
Description
Technical field
The present invention relates to silica gel mould field, the making side of especially a kind of low-pressure injection mold using silica gel sliding block
Method.
Background technology
In low-pressure injection technique and its process of mold, because of the structure problem of product, the processing of mold can be caused
It is middle many back-off positions occur.Such as use the mold insert and slider designs mold of traditional analogy injection mold, the then life of mold
It produces difficulty and workload is very big, precise requirements are very high, while there are many manufacturing cost and production cycle, made in small lot production
At the excessive problem of cost, or even many structures can not need to carry out two after mold is molded simply by simultaneous manufacturing
Secondary processing, step are complicated.
Invention content
In order to solve the above-mentioned technical problem providing one kind can have back-off to tie by using silica gel sliding block one-pass molding
The production method of the low-pressure injection mold using silica gel sliding block of the product of structure.
A kind of production method of low-pressure injection mold using silica gel sliding block, including：
S1, original paper map file is drawn：The map file that product to be produced carries out the product structure is selected to draw；
S2, revision mold prototype map file：It determines the back-off position of product to be produced, and the map file in S1 is revised,
Cuboid block, and the cuboid block and the product to be produced residing for the back-off structure are coated on the outside of the back-off structure
Surface is bonded；
S3, low pressure mold prototype is made：Mold prototype is carried out according to revised map file in S2；
S4, back-off structure map file is drawn：The cuboid block coated in S2 is depicted as individual map file；
S5, silica gel sliding block is made, silica gel sliding block making is carried out using silica gel materials according to the map file drawn in S4；
S6, unitary mould make, the mould that all silica gel sliding blocks made in S5 are arranged according to the map file of S1 in S3
Have in prototype；
S7, low pressure die perfusion carry out low-pressure injection to mold obtained in S6；
S8, product are completed, and unitary mould obtained, obtained half production containing the silica gel sliding block after perfusion in S7 are taken out
Product remove the silica gel sliding block, and double of product carries out refine processing, obtains finished product.
Preferably, in S5, all silica gel sliding blocks are left and right mold-opening structure.
Preferably, in S2, square block is coated on the outside of the back-off structure.
Preferably, in S2, the size of the cuboid block is all higher than the size of the back-off structure.
Wherein, the back-off structure is the structure in the die sinking direction for hindering integral product, i.e. the die sinking mode of integral product
For upper lower open die when, the die sinking mode of the back-off structure is left and right die sinking or front and back die sinking.
The production method of low-pressure injection mold provided by the invention using silica gel sliding block passes through falling product to be formed
Buckle structure carries out separately formed support silica gel sliding block, and when making prototype, will be in the size merging prototype of silica gel sliding block so that
After making prototype mold, silica gel sliding block can be directly placed in prototype mold, carry out unified perfusion, and in prototype mold
After die sinking, silica gel sliding block is removed, finished product is obtained.
Specific implementation mode
The present invention is described in further details with reference to specific embodiment：
A kind of production method of low-pressure injection mold using silica gel sliding block, including：
S1, original paper map file is drawn：The map file that product to be produced carries out the product structure is selected to draw, wherein map file includes
Three-dimensional drawing and two-dimentional drawing；
S2, revision mold prototype map file：It determines the back-off position of product to be produced, and the map file in S1 is revised,
Cuboid block, and the cuboid block and the product to be produced residing for the back-off structure are coated on the outside of the back-off structure
Surface is bonded, i.e., is soon coated the back-off structure completely by the cuboid；
S3, low pressure mold prototype is made：Mold prototype is carried out according to revised map file in S2；
S4, back-off structure map file is drawn：The cuboid block coated in S2 is depicted as individual map file, wherein the map file
Outwardly and inwardly structure including cuboid block, particularly, the internal structure of cuboid block and the corresponding back-off structure
It is identical；
S5, silica gel sliding block is made, silica gel sliding block making is carried out using silica gel materials according to the map file drawn in S4；
S6, unitary mould make, the mould that all silica gel sliding blocks made in S5 are arranged according to the map file of S1 in S3
Have in prototype；
S7, low pressure die perfusion carry out low-pressure injection to mold obtained in S6；
S8, product are completed, and unitary mould obtained, obtained half production containing the silica gel sliding block after perfusion in S7 are taken out
Product remove the silica gel sliding block, and double of product carries out refine processing, obtains finished product.
Preferably, in S5, all silica gel sliding blocks are left and right mold-opening structure, and the mold prototype is generally up and down
Mold-opening structure.
Preferably, in S2, square block, the length, width and height all same of square block, side are coated on the outside of the back-off structure
Just it is operated when drawing map file.
Preferably, in S2, the size of the cuboid block is all higher than the size of the back-off structure, i.e., the described cuboid
