Abstract
The invention discloses a rear mold insert structure and a machining process. The rear mold insert comprises a crescent insert body formed integrally, and the top end surface of the insert body is provided with a forming surface; three center grooves are formed in the insert body and distributed in an isosceles triangle shape. The machining process includes the steps of blank forging, milling of the bottom end surface, milling of the forming surface and the center grooves, deburring by bench workers, and inspection and warehousing. The shape of the rear mold insert structure is reasonably designed according to the shape of a product to be molded in an injection mode, the damage possibility of the insert during installation is lowered to the maximum extent, and the insert is convenient to mount and dismount. Compared with an existing combined type insert, the insert is formed integrally, the outline is obtained through linear cutting, and the forming surface is milled through a CNC machine tool, so that assembling errors are effectively avoided, and the precision of products is remarkably improved.
Description
Technical field
The present invention relates to the technical field of structures of plastic cement products mould, particularly relate to rear mold insert structure and processing technique.
Background technology
Along with improving constantly of technology, the fast development of plastic cement products industry, the diversification structure of all kinds of plastic cement parts becomes increasingly complex, quality requirements is the strictest, the highest to plastic cement products industry requirement, competition is the fiercest, how to ensure that similar plastic cement products occurs without exception, the production cycle that maximized guarantee Product processing is effective, stable in process of production.In the positioning chamber that the rear mold mold insert of existing mold is typically installed in rear pattern plate bottom it, B plate is formed, rear mold mold insert assembly, as the important component part of mould, directly affects the quality of injecting products.It is therefore desirable to design a kind of rational in infrastructure rear mold mold insert that can ensure that Product Precision.
Summary of the invention
For the technical problem of above-mentioned existence, it is an object of the invention to: propose a kind of rear mold insert structure guaranteeing Product Precision and processing technique.
The technical solution of the present invention is achieved in that a kind of rear mold insert structure, including integrated crescent mold insert main body；The top end face of described mold insert main body is provided with forming surface；Three thimble grooves are offered in described mold insert main body；Described three thimble grooves are the position distribution of isosceles triangle.
Preferably, one of them thimble groove of described three thimble grooves is positioned at the middle part of crescent big circumference, and two other thimble groove is positioned at inner side two point of crescent small circumference.
Preferably, described forming surface is the crescent shape that middle part is protruding.
The processing technique of a kind of rear mold insert structure, comprises the following steps:
(1), rough forging；
(2), milling bottom face: bottom face is processed into plane by milling machine；
(3), line cutting agent structure: on the basis of bottom face, slow silk thread cuts the profile of crescent mold insert main body；
(4), milling forming surface and thimble groove: on the basis of the bottom face and profile of mold insert main body, use CNC Digit Control Machine Tool and the forming surface of electric spark processes mold insert main body top end face and three thimble grooves；
(5), pincers worker deburring；
(6), inspection warehouse-in.
Due to the utilization of technique scheme, the present invention compared with prior art has the advantage that
1, the present invention structure by appropriate design rear mold mold insert, owing to treating that the outline of injecting products is crescent, is therefore designed to crescent shape by the structure of rear mold mold insert, can reduce the mold insert probability of damaging when assembling to greatest extent, and can be convenient to install, dismantle；
2, compared with existing combination type mold insert, the present invention, by mold insert is one-body molded, can avoid the occurrence of rigging error, and, when being processed into profile, use CNC processing and spark machine electro-discharge machining, the phenomenon occurring that mold insert deforms can be reduced in the course of processing, be remarkably improved its precision.
Accompanying drawing explanation
Below in conjunction with the accompanying drawings technical solution of the present invention is described further:
Accompanying drawing 1 is the structural representation of the rear mold mold insert of the present invention.
Wherein: 1, mold insert main body；2, forming surface；3, thimble groove.
Detailed description of the invention
The present invention is described below in conjunction with the accompanying drawings.
The rear mold insert structure of the present invention, as shown in Figure 1, including integrated crescent mold insert main body 1；The top end face of described mold insert main body 1 is provided with forming surface 2；Three thimble grooves 3 are offered in described mold insert main body 1；Described three the thimble grooves 3 position distribution in isosceles triangle.
Further instruction, one of them thimble groove of described three thimble grooves 3 is positioned at the middle part of crescent big circumference, two other thimble groove is positioned at inner side two point of crescent small circumference, and the reasonable layout of thimble groove can make product appearance reduce thimble vestige and thimble overlap as far as possible.
Further instruction, described forming surface 2 is the crescent shape that middle part is protruding.
The processing technique of the rear mold insert structure of the present invention, comprises the following steps:
(1), rough forging；
(2), milling bottom face: bottom face is processed into plane by milling machine；
(3), line cutting agent structure: on the basis of bottom face, slow silk thread cuts the profile of crescent mold insert main body；
(4), milling forming surface and thimble groove: on the basis of the bottom face and profile of mold insert main body, use CNC Digit Control Machine Tool and the forming surface of electric spark processes mold insert main body top end face and three thimble grooves；
(5), pincers worker deburring；
(6), inspection warehouse-in.
The rear mold insert structure of the present invention, its shape, according to treating the profile appropriate design of injecting products, can reduce the probability of damaging when mold insert is installed to greatest extent, and be convenient to install, dismounting.Compared with existing combination type mold insert, the present invention, by mold insert is one-body molded, use line cutting profile, CNC Digit Control Machine Tool milling forming surface, is prevented effectively from and rigging error occur, be remarkably improved Product Precision.
Above-described embodiment is only for technology design and the feature of the explanation present invention; its object is to allow person skilled in the art will appreciate that present disclosure and to be carried out; can not limit the scope of the invention with this; all equivalence changes made according to spirit of the invention or modification, all should contain within the scope of the present invention.
