Abstract

The utility model discloses a molding die for a product with a through hole, which comprises a male die, a female die matched with the male die, a sliding mechanism and an insert, wherein the sliding mechanism comprises a sliding block and an inclined guide pillar, the sliding block is positioned between the male die and the female die and connected with the male die in a sliding manner, an empty cavity is arranged on one side of the sliding block facing to the male die, the empty cavity of the sliding block is matched with the male die and the female die for forming a cavity for molding the product, the siding block and the female die are respectively provided with penetration holes which are communicated with the empty cavity relative to the upper part of the empty cavity, the insert is fixed on the female die, the insert penetrates into the penetration holes, and the end part of the insert extends into the empty cavity of the sliding block in the sliding manner for molding the through hole of the product. The molding die for the product with the thorough hole can avoid damaging the appearance surface of the empty cavity of the sliding block due to the friction with the insert by laterally inserting the sliding block between the female die and the male die and forming the through hole of the product by penetrating the sliding block and inserting into the insert when the sliding block stops, thereby ensuring the molded product to have the appearance surface with higher precision.

Description

Band through hole formed product mould

Technical field

The utility model relates to a kind of mould, relates in particular to a kind of band through hole formed product mould.

Background technology

Mould industry is a basic industry in the manufacturing industry, it is the basis that technological achievement transforms, itself be again the key areas of new high-tech industry simultaneously, along with making constant progress of science and technology, the continual renovation of product is regenerated, at computer, communication, in consumption electronic products and various precision instrument and the mould thereof, formed product quality requirement to each spare and accessory parts is also more and more higher, also more and more stricter to the mould designing requirement, require the appearance of institute's shaped article to have degree of precision and meet requirement attractive in appearance, thereby the mold cavity surface that mould is used for shaped article has been proposed high-precision requirement.Mould is to be used for the instrument of formed article, and different moulds is made of different parts.It mainly realizes the processing of article profile by the change of institute's moulding material physical state.General mould includes male model and master mold, and the two cooperates the formation die cavity, is used for shaped article, after the product injection molding process finishes, the male and female mould is separated the taking-up shaped article.And, also include the modular unit that other are used for moulding for the mould of product with special construction.The mould of traditional product with through hole is generally cooperated by mold insert and forms.

As shown in Figure 1, the forming through hole technology of existing band through hole formed product mould adopts cooperating of a fixed mold insert 14 ' and slide block 16 ', the end 141 ' of described mold insert 14 ' is cylindric, big or small outline with the required through hole of offering 101 ', the end 141 ' of described mold insert 14 ' is arranged on the cavity of offering in the slide block 16 ' 162 ' that is used for the shaped article part-structure, can form the through hole 101 ' of required product thus.Yet, the band through hole formed product mould of this structure, must make the upper end of mold insert 14 ' peak at slide block 16 ', the unavoidable like this apperance face phase mutual friction that makes mold insert 14 ' upper end with slide block cavity 162 ', thereby the apperance surface wear that makes slide block cavity 162 ' causes the Surface Appearance of moulding impaired, and the outward appearance precision can't reach requirement.

The utility model content

The purpose of this utility model is to provide a kind of band through hole formed product mould at above-mentioned the deficiencies in the prior art, this band through hole formed product mould can prevent to form the mold cavity surface of Surface Appearance in the shaped article through hole impaired, has the appearance of degree of precision to guarantee shaped article.

For achieving the above object; the utility model provides band through hole formed product mould to include the male model that forms the product core; the master mold that cooperates with described male model; slide mechanism and mold insert; described male model is connected with male model benevolence; described master mold is connected with mother module core; described slide mechanism comprises slide block and Angle Pin; offer oblique guide hole on described slide block one end; described Angle Pin is bending and passes the oblique guide hole of described slide block slidably; the described slide block other end is slidingly connected between described male model and master mold and with described male model; described slider surface offers cavity to a side of described male model; described slide block cavity and described male model benevolence; mother module core cooperates the formation die cavity; described die cavity is for shaped article; it is characterized in that: described slide block and described master mold offer perforation respectively with respect to described slide block cavity top; described perforation is communicated with described cavity; described mold insert is fixed on the master mold, thereby mold insert penetrates described perforation and its end is stretched in the cavity of described slide block slidably to the formed product through hole.

As mentioned above, the utility model band through hole formed product mould is inserted slide block by side between master mold, male model, treat to pass when slide block stops described slide block and insert the through hole that mold insert comes shaped article, avoided the cavity surface and the friction of described mold insert of slide block impaired, thereby guaranteed that the product of moulding has the appearance of degree of precision.
