Abstract

The utility model provides an insert replacing structure which ensures that an insert can be conveniently and fast replaced. The insert replacing structure comprises a lower mold core. An insert putting opening is placed on a position corresponding to the lower mold core. The lower mold core is provided with a positioning pin corresponding to an insert. The insert is clamped by the positioning pin through a positioning pin mounting hole and an adjusting bolt. A groove hole corresponding to the positioning pin is placed on the insert. The insert replacing structure is characterized in that the groove hole is a threaded hole, and a pin head of the positioning pin is screwed in the threaded hole.

Description

Mold insert is changed structure

Technical field

The utility model relates to the technical field of watering injection molding, is specially mold insert and changes structure.

Background technology

The client who makes as required shaped article is different, change different trade mark mold inserts, existing replacing insert structure as shown in Figure 1, lower die model core 9 correspondence positions are provided with mold insert and put into mouth 8, counterdie 2 is provided with alignment pin 5 with the correspondence position of mold insert 7, alignment pin 5 blocks V-shaped groove 6 on mold insert by alignment pin installing hole 3 and adjusting bolt 4, before matched moulds, put into mouthfuls 8 to what mold insert 7 put into that lower die model core 9 correspondence positions set, when changing mold insert 7, rotation adjusting bolt 4 is taken out alignment pin 5, then is changed mold insert 7.There is a defective in this structure, due to the taking-up alignment pin, then will take out and insert, and the stroke of taking-up is longer, still relatively requires great effort.

Summary of the invention

For the problems referred to above, the utility model provides a kind of mold insert to change structure, can change convenient, quickly mold insert.

Its technical scheme is such, it comprises lower die model core, described lower die model core correspondence position is provided with mold insert and puts into mouth, the correspondence position of described lower die model core and mold insert is provided with alignment pin, described alignment pin blocks mold insert by alignment pin installing hole and adjusting bolt, the slotted eye corresponding with described alignment pin arranged on described mold insert, it is characterized in that: described slotted eye is screwed hole, and the plunger of described alignment pin is rotatably connected in described screwed hole.

It is further characterized in that: all the other sides at the body of described mold insert are provided with the screwed hole supporting with alignment pin.

In said structure of the present utility model, because slotted eye corresponding with alignment pin on mold insert changes screwed hole into, the plunger of alignment pin is rotatably connected in screwed hole, and like this, the taking-up alignment pin just can be taken away and insert simultaneously, and is more laborsaving, quick.And, be provided with the screwed hole supporting with alignment pin in all the other sides of the body of mold insert, can be adapted to so different moulds and use, flexibility, suitability are better.

The specific embodiment

See Fig. 2, Fig. 3, the utility model comprises patrix 1, counterdie 2, lower die model core 9, lower die model core 9 correspondence positions are provided with mold insert and put into mouth 8, counterdie 2 is provided with alignment pin 5 with the correspondence position of mold insert 7, and alignment pin 5 blocks screwed hole 6 on mold insert by alignment pin installing hole 3 and adjusting bolt 4, before matched moulds, put into mouthfuls 8 to what mold insert 7 put into that lower die model core 9 correspondence positions set, adjusting bolt 4 is put into alignment pin 5 screwed hole 6 of mold insert 7 and is located, and has prevented rocking of mold insert 7; When changing mold insert 7, rotation adjusting bolt 4 is taken out alignment pin 5, because plunger and the screwed hole 6 of alignment pin spins, takes out like this alignment pin 5 and just can take away simultaneously mold insert 7, reaches the purpose of replacing mold insert.And also being provided with screwed hole 10 in all the other sides of mold insert 7, such improvement is more suitable for different moulds to use, and improves suitability.
