Description

Injection Mould With Automatic Thread Demoulding tool

Technical field

The utility model relates to a kind of mold, especially a kind of Injection Mould With Automatic Thread Demoulding tool.

Background technique

When using injection mold injection-molded item, internal thread structure is often had on product, the type for forming product is intracavitary just Must have with externally threaded type core, it is very troublesome when with the demoulding of externally threaded type core after injection molding, cause mold overall structure Complexity, processing cost is high, inconvenient.

Summary of the invention

The purpose of this utility model provide a kind of structure is simple, thread core demoulding is easy, low manufacture cost, after die sinking i.e. The Injection Mould With Automatic Thread Demoulding tool that thread core can be deviate from, improve working efficiency.

The Injection Mould With Automatic Thread Demoulding of the utility model has, including solid plate and moving template, has bottom plate below moving template, It is respectively equipped with fixed die insert and moving die insert on solid plate and moving template, forms product type between moving die insert and fixed die insert Chamber；Backing plate is bolted on moving template, being located above backing plate in moving template has small push plate backboard and small push plate, screw rod Lower end insertion end plate on hole in, end plate is fixedly connected with bottom plate, equipped with lower bearing between screw rod and end plate, the upper end of screw rod It is connected with type core extension bar, thread core is terminated on type core extension bar, has external screw thread on the outside of thread core upper end, the external screw thread It is intracavitary to partially protrude into type, upper bearing (metal) is equipped between type core extension bar and small push plate backboard, backing plate, in type core extension bar and pad Intermediate bearing is equipped between plate, the screw-casing to match with screw rod is fixedly connected with lower liftout plate and upper ejector plate；Screw-casing and spiral shell It is non-self-lock-ing state between bar.

It is connected between the screw rod upper end and type core extension bar for plug-in type, in the insert type core extension bar of screw rod upper end, The section of insertion portion is square, to prevent from relatively rotating；It is fixed between type core extension bar and thread core by connecting bolt Connection.

The Injection Mould With Automatic Thread Demoulding of the utility model has, and installs the ejection mobile mechanism of liftout plate and injection-moulding device at present Connect, when being opened after injection molding, moving die insert is moved down first, and the part being located in fixed die insert on product is exposed, while injection molding is set Standby that lower liftout plate is pushed to move up, screw-casing moves up, and under the non-rotary situation of screw-casing, screw rod rotation drives thread core to turn It is dynamic, the threaded connection part between thread core and product is separated, achievees the purpose that thread core demoulds.With structure letter Single, thread core can deviate from thread core after demoulding easy, low manufacture cost, die sinking, improve the advantages of working efficiency.

Detailed description of the invention

Fig. 1 is the structural schematic diagram of specific embodiment of the present invention.

Specific embodiment

As shown in Figure 1：The Injection Mould With Automatic Thread Demoulding of the utility model has, including solid plate 15 and moving template 20, dynamic model Plate 20 has bottom plate 21 below, fixed die insert 14 and moving die insert 16 is respectively equipped on solid plate 15 and moving template 20, in dynamic model Product type chamber is formed between insert 16 and fixed die insert 14.Backing plate 19, moving template 20 have been bolted on moving template 20 The interior backing plate 19 that is located at has small push plate backboard 18 and small push plate 17 above.Screw rod 6 lower end insertion end plate 1 on hole in, end plate 1 with Bottom plate 21 is fixedly connected.Lower bearing 2 is equipped between screw rod 6 and end plate 1.The upper end of screw rod 6 is connected with type core extension bar 10, type core It is terminated with thread core 12 on extension bar 10, has external screw thread on the outside of 12 upper end of thread core, which extend into type chamber It is interior.Upper bearing (metal) 9 is equipped between type core extension bar 10 and small push plate backboard 18, backing plate 19.In type core extension bar 10 and backing plate 19 Between be equipped with intermediate bearing 7, with screw rod 6 match screw-casing 5 be fixedly connected with lower liftout plate 3 and upper ejector plate 4.Screw-casing 5 It is non-self-lock-ing state between screw rod 6, if screw-casing 5 moves linearly, screw rod 6 can rotate.

It is connected between 6 upper end of screw rod and type core extension bar 10 for plug-in type, in 6 upper end insert type core extension bar 10 of screw rod, The section of insertion portion is square, to prevent from relatively rotating.Pass through connection bolt between type core extension bar 10 and thread core 12 It is fixedly connected.

The Injection Mould With Automatic Thread Demoulding of the utility model has, and installs the ejection moving machine of liftout plate 3 and injection-moulding device at present Structure connects, and when being opened after injection molding, moving die insert 16 is moved down first, and the part being located in fixed die insert 14 on product 13 is exposed, together When injection-moulding device push lower liftout plate 3 to move up, screw-casing 5 moves up, and under the non-rotary situation of screw-casing 5, screw rod 6 is rotated, band Dynamic thread core 12 rotates, and separates the threaded connection part between thread core 12 and product 13, and it is de- to reach thread core 12 The purpose of mould.With structure, simple, thread core 12 can deviate from thread core after demoulding easy, low manufacture cost, die sinking, mention The advantages of high working efficiency.
