A kind of cost-effective injection mold of the present invention has and improves labor productivity, reduces cost of investment, subtracts
The advantages that having lacked operating cost.
Description of the drawings
Attached drawing 1 is the dimensional structure diagram of cost-effective one preferred embodiment of injection mold of the invention.
The label of each component is as follows in attached drawing：1, upper mold, 2, lower die, 3, column.
Specific implementation mode
The preferred embodiments of the present invention will be described in detail below in conjunction with the accompanying drawings, so that advantages and features of the invention energy
It is easier to be readily appreciated by one skilled in the art, so as to make a clearer definition of the protection scope of the present invention.
Referring to Fig. 1, Fig. 1 is a kind of cost-effective injection mold of the present invention, the cost-effective injection mold packet
Upper mold, detent mechanism 3 and lower die 2 are included, the upper mold 1 and 2 both ends of the lower die open up grooved hole, and the detent mechanism 3 is fixed
In the slot, 1 bottom of the upper mold is equipped with insert, and the insert has multiple first seamed edges parallel to each other, described every
A first seamed edge is each formed with cutting edge, and the insert is cuboid, and two opposing end surfaces of the cuboid are square, described
Detent mechanism is cylinder column, and the upper mold includes inlay, and the inlay is made of exhaust steel, and the upper mold 1 is quiet
Mould, the lower die 2 are dynamic model, and the number of the slot is 2, and the thickness of the exhaust steel is the ㎜ of 2 ㎜~5, the lower die
Bottom is equipped with reinforcing rib.It can be divided into the modern designs of plastics, casting mold mould, stamping die, forge mould and graphite electrode by function and usage and grind master mold.
It can be divided into low-cost die by pattern-making material and be also referred to as soft mode, economic mould or non-steel die and steel hard mold root.According to different moulders
Process, fast mould can divide direct fast mould and indirect fast mould.The modern designs of plastics, casting mold mould, stamping die, forge mould and stone
Electrode ink grinds master mold.These we all familiar, so just do not say herein, I first for everybody introduce it is soft and
Hard rapid die design.Soft mold is different from tradition because of soft material (such as silicon rubber, epoxy resin) used in it
Steel material and gain the name, the soft mold manufacturing method proposed at present mainly has silicon rubber casting, spray-gun process, resin
Casting etc..The quantity of soft mold article of manufacture is generally 50~5000, for up to ten thousand or even the product of hundreds of thousands part,
There is still a need for traditional steel moulds.What die hard referred to is exactly steel mould, utilizes the main of RP prototype steel moulds
Method has investment casting, even if it is also indirect molding, silicon rubber mould that silicon rubber mould Rapid Manufacturing Technology, which belongs to soft mold,
Tool manufacturing process is a kind of rapid tooling manufacturing method that comparison is universal.Since silicon rubber mould has good flexible and bullet
Property, zero of complicated, decorative pattern finely, without pattern draft or even with pattern draft and with deep groove class can be made
Part, fabrication cycle is short, and parts quality is high, thus is concerned.(1) prototype table is to processing.The prototype that RP methods make is in its lamination
Generally there are step line or gap between tomography, polishing need to be carried out and antiseepage and intensive treatment etc. are smooth to improve the table of prototype
Degree and moisture-resistant part and heat resistanceheat resistant part etc..Only prototypic surface smooth enough just can guarantee the fat finish of the silica gel model of making,
And then ensure that the product for turning over system only has higher surface quality and convenient for being taken out from Silicon moulds.(2) making type frame and fixed original
Type.The shape and size of the requirement design casting type frame of geometric dimension and Silicon moulds glue according to prototype, the size of type frame are small suitable
In.Before fixed prototype, need to determine the determination of the position die joint and gate location of die joint and cast gate be it is highly important,
It directly affects the quality for pouring into a mould product energy person smooth demoulding and product casting quality.When die joint and cast gate are selected and are handled
After, it just will be in prototype fixed frame.（3) silicon rubber metering, mixing and vacuum defoamation.Silicon rubber dosage should be according to made
The proportion of curved cabinet size and silicon rubber accurately measures.The silicon rubber measured is inserted to the curing agent of proper proportion, stirring is equal
Vacuum defoamation is carried out after even.Inclined heated plate should be grasped according to the vacuum degree reached.(4) silicon rubber cast and solidification.Brick rubber
It is poured into after mixture vacuum defoamation in the type frame for having fixed prototype.In casting process, certain skill should be grasped.Silicon rubber
After glue cast, to ensure that mold filling is intact, vacuum defoamation is carried out again.The purpose of deaeration is to mix silicon in extraction casting process
Gas in glue and the gas being closed in prototype cavity, the time of this time deaeration should suitably add than the inclined heated plate before cast
Long, the specific time should be depending on the operable time of selected silastic material and prototype size.After deaeration, Silicon moulds can
Voluntarily harden or heat hardening.Heating hardening can shorten firm time.（5) dismounting type frame, knife split mould and take out prototype.When
After silicon rubber mould hardening, you can type frame is removed and removes runner stick etc..Mould is splitted with reference to the label progress knife of prototype die joint,
Prototype is taken out, and necessary cleaning is carried out to the cavity of silicon rubber mould, made silicon rubber mould can be utilized in vacuum shape
The manufacture of resin or plastic product is carried out under state.The present invention provides a kind of cost-effective injection mold, has and improves labour
The advantages that production efficiency reduces cost of investment, reduces operating cost.
The specific implementation mode of the present invention, but scope of protection of the present invention is not limited thereto, any to be familiar with this field
Within the technical scope disclosed by the invention, changes or substitutions that can be made without creative work should all be contained technical staff
Lid is within protection scope of the present invention.Therefore, protection scope of the present invention should be to protect model defined by claims
Subject to enclosing.
