Description
Technical field
The present invention relates to mould applications more particularly to a kind of injection mould for insert.
Background technique
Injection mold is a kind of tool for producing plasthetics；Also plasthetics complete structure and accurate dimension are to confer to
Tool.Injection mold is made of dynamic model and cover half two parts, and dynamic model is mounted on the moving die plate of injection molding machine, and cover half is mounted on note
On the fixed form of molding machine.In injection moulding, dynamic model and cover half closure constitute running gate system and type chamber, dynamic model and fixed when die sinking
Mould separates to take out plastic products.
The technical process of metal insert injection molding is that metal insert is first fixed position appropriate in a mold in advance, then again
Injected plastic molding, the inserts cured plastics that are cooled pack tightly to obtain plastic after die sinking.To guarantee inserts in process of injection molding
In do not move, avoid molding when damage mold, be considered as when design this kind of mold the fixation of inserts in a mold with can
By positioning, and consider the placement and abjection of inserts.
Summary of the invention
According to the above technical problem, the present invention provides a kind of injection mould for insert, including solid plate, moving template, mandril, stream
Road, it is characterised in that further include folder, mobile bar, hydraulic cylinder, folder slot, offers insert pocket on one end face of solid plate,
Inserts is installed in the insert pocket, the inserts includes screw rod, the shaft shoulder, and a part of the screw rod is mounted in insert pocket,
The shaft shoulder is fixed on the outside of the screw rod, the shaft shoulder is located at solid plate side, accompanies folder, the folder on the outside of the screw rod
Inside is equipped with screw thread, and the screw thread on screw thread and screw rod on the inside of the folder cooperates, and the solid plate is equipped with folder slot,
The folder slot is connected with insert pocket, and the folder is connect with mobile bar one end, the mobile bar other end pass through folder slot,
It being connect after solid plate with hydraulic cylinder, the solid plate side is equipped with moving template, the depressed section on the moving template and the shaft shoulder,
Forming cavity is enclosed between screw rod, and gasket is installed between the shaft shoulder and the end face of moving template, the moving template is equipped with runner,
The runner is connected to type chamber, and guide rod is equipped on the moving template, and fixed block, the dynamic model are equipped on the guide rod
Plate is equipped with guide groove, and the guide groove side opens up fluted, and the groove is connected to guide groove, is equipped in the groove
Spring, the guide rod assign into guide groove, and the fixed block is located in groove, and the fixed block is contacted with spring.
Described mandril one end passes through solid plate and is located in insert pocket.
The side of the fixed block is not contacted with the side wall of groove, and the length of the groove is less than guide groove.
Beneficial effects of the present invention are：Moving template and solid plate of the present invention clamp the shaft shoulder of inserts, prevent inserts axial
Mobile, the screw flight connection of folder and inserts can prevent inserts from rotating, because if it happens inserts rotates inherently
Generating axial movement, this is contradicted with the foregoing description, and then inserts is completely fixed, and when demoulding, hydraulic cylinder can pass through shifting
Lever drives folder to fall back in folder slot, separates folder with inserts, mandril will not be interfered to eject inserts, and mandril ejects inserts
Rather than the cured parts of plastics of ejection, this avoid parts of plastics to fall the marking because being ejected by mandril, and gasket
With sealing function, plastics liquid can be prevented from the intracavitary outflow of type, and spring has buffer function, in molding, spring pair
Fixed block applies resistance, prevents solid plate and moving template generates excessive collision, and the length of groove is smaller, replacement get up spring compared with
Convenient, fixed block is not contacted with groove inner wall, and fretting wear will not occur between the two.

Specific embodiment
According to the figure, invention is further explained for root：
Embodiment 1
The present invention is a kind of injection mould for insert, including solid plate 1, moving template 8, mandril 17, runner 11, it is characterised in that
Further include folder 4, mobile bar 6, hydraulic cylinder 7, folder slot 5, insert pocket 2 is offered on 1 one end face of solid plate, inserts 3 is mounted on
In insert pocket, inserts 3 includes screw rod 31, the shaft shoulder 32, and a part of screw rod 31 is mounted in insert pocket 2, and 32 fixing sleeve of the shaft shoulder exists
31 outside of screw rod, the shaft shoulder 32 are located at 1 side of solid plate, and folder 4 is clipped in 31 outside of screw rod, is equipped with screw thread, folder 4 on the inside of folder 4
