Abstract
The invention discloses a kind of plastic mould elongated straight pocket machining techniques, include the following steps：Step 1: processing cavity External Shape；Step 2: the endoporus of cavity parts is first opened slightly with slow wire feeding, the unilateral surplus for staying 0.10mm, then ground with interior round pierce punch grinding machine, when processing, can ensure that verticality within 0.005mm, finally polishes endoporus to minute surface with concentricity along stripping direction；Step 3: the top of the endoporus of cavity parts is molded orifice chamfer using Wire EDM, the present invention can ensure the concentricity and verticality of cavity parts, cavity parts surface is avoided to pull, is worth promoting.
Description
Technical field
The present invention relates to plastic mould processing technique field, specifically a kind of plastic mould elongated straight pocket machining technique.
Background technology
As shown in fig. 6, product appearance both ends size is the same（Size has required precision）, product plastic raw materials are foaming
PS, corresponding mold cavity are without stripping slope, it is desirable that mirror finish, concentricity has required precision etc., in processing cavity, to work
Skill requirement is very high.Pocket machining technique of the prior art is the shape of first workpieces processing, and cavity endoporus is using silk thread cutting of being careful.
With following defect：First, cavity is round, and concentricity precision does not reach requirement；2nd, slow silk cannot good verticality, mold
In production, product surface is easily pulled.
Invention content
The purpose of the present invention is to provide a kind of plastic mould elongated straights for the concentricity and verticality for ensureing cavity parts
Pocket machining technique, to solve the problems mentioned in the above background technology.
To achieve the above object, the present invention provides following technical solution：
A kind of plastic mould elongated straight pocket machining technique, includes the following steps：
Step 1: processing cavity External Shape；
Step 2: the endoporus of cavity parts is first opened slightly with slow wire feeding, the unilateral surplus for staying 0.10mm, then ground with interior round pierce punch grinding machine
Mill, when processing, can ensure that verticality within 0.005mm, finally prolongs stripping direction and polish endoporus to minute surface with concentricity；
Step 3: the top of the endoporus of cavity parts is molded orifice chamfer using Wire EDM.
As further embodiment of the present invention：Digital control processing lathe process cavity parts shape is used in the step 1.
As further scheme of the invention：The endoporus of cavity parts opens what is slightly used with slow wire feeding in the step 2
Equipment is the unidirectional wire electric spark wire cutting machine of low speed.
Compared with prior art, the beneficial effects of the invention are as follows：The processing technology of the present invention has the following advantages：
First, the concentricity precision of cavity parts is guaranteed；
2nd, the verticality of cavity parts is guaranteed.

Specific embodiment
The technical solution of this patent is described in more detail With reference to embodiment.
- 6 are please referred to Fig.1, a kind of plastic mould elongated straight pocket machining technique includes the following steps：
Step 1: processing cavity External Shape；
Step 2: the endoporus of cavity parts is first opened slightly with slow wire feeding, the unilateral surplus for staying 0.10mm, then ground with interior round pierce punch grinding machine
Mill, when processing, can ensure that verticality within 0.005mm, finally prolongs stripping direction and polish endoporus to minute surface with concentricity；
Step 3: the top of the endoporus of cavity parts is molded orifice chamfer using Wire EDM.
Digital control processing lathe process cavity parts shape is used in step 1；
It is the unidirectional wire electric spark wire cutting machine of low speed that the endoporus of cavity parts, which opens the equipment slightly used with slow wire feeding, in step 2.
It is an advantage of the invention that：The processing technology of the present invention has the following advantages：First, the concentricity precision of cavity parts obtains
Ensure；
2nd, the verticality of cavity parts is guaranteed.
The better embodiment of this patent is explained in detail above, but this patent is not limited to above-mentioned embodiment party
Formula, can also be under the premise of this patent objective not be departed from the knowledge that one skilled in the relevant art has
Various changes can be made.
