Abstract
The invention discloses a forming structure of an injection moulding machine; the forming structure is characterized by comprising a mould cavity formed by a fixed part and a movable part; the mould cavity comprises a main runner (1) and a branch runner (2); the main runner is communicated with a nozzle of the injection moulding machine; the fixed part comprises a fixed end installation plate (3), and a diaphragm (4) installed on the fixed end installation plate (3); a locating ring (5) is arranged at the other end of the fixed end installation plate (3); and furthermore, the main runner (1) is arranged at the axis center of the locating ring (5). A plurality of ejector pins are arranged on the movable part of the forming structure, so that the rapid release can be realized.
Description
Technical field
The invention belongs to the technical field of injection machine parts, particularly, what the present invention relates to is a kind of molding structure of injection machine.
Background technology
Injection machine is the processing equipment that in Plastics Processing Industry, use amount is maximum, not only has a large amount of products directly can produce with injection machine, but also is the key equipment of composition injection stretch blow moulding.China has become the first big country that world's molding machine platform part is produced, promotes that the reason that Chinese injection machine equipment manufacture industry develops is: one is carry out joint and technological cooperation with internationally famous enterprise; Two is that the international Bian that Chinese Enterprise has adapted to component of machine gradually purchases mode, has grasped Bian and has purchased channel.Meanwhile, the production of China's injection machine also presents very strong regional characteristics, the ground such as the Ningbo in Zhejiang and the Dongguan in Guangdong, has become China and even global important injection machine production base.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of molding structure of injection machine, and movable part of the present invention arranges multiple thimble, can realize fast demoulding.
It is realize by the following technical solutions that the present invention solves the problems of the technologies described above:
A molding structure for injection machine, comprises the die cavity formed by standing part and movable part; Described die cavity and comprise sprue and runner; Described sprue is communicated with the nozzle of injection machine.
In technique scheme, polymer fluid enters sprue and runner from nozzle, thus shaping in described die cavity.
Described standing part comprises stiff end installing plate and is arranged on the barrier film on described stiff end installing plate.
The other end of described stiff end installing plate is provided with locating ring, and described sprue is located at the shaft core position of described locating ring.
Described movable part comprises the mobile terminal installing plate, movable top plate, partition, the core rod that set gradually; Further, described movable top plate is arranged 3 thimbles, described thimble contacts with die cavity through described partition, core rod.
Compared with prior art, the beneficial effect had is in the present invention: movable part of the present invention arranges multiple thimble, can realize fast demoulding.
Accompanying drawing explanation
The present invention is described in detail below in conjunction with the drawings and specific embodiments;
Fig. 1 is the structural representation of embodiment 1.
The component names that in figure, each Reference numeral is corresponding is: 1-sprue; 2-runner; 3-stiff end installing plate; 4-barrier film; 5-locating ring; 6-mobile terminal installing plate; 7-movable top plate; 8-partition; 9-core rod; 10-thimble.
detailed description of the invention
The technological means realized for making the present invention, creation characteristic, reaching object and effect is easy to understand, below in conjunction with detailed description of the invention, setting forth the present invention further.
Embodiment 1
A molding structure for injection machine, comprises the die cavity formed by standing part and movable part; Described die cavity and comprise sprue 1 and runner 2; Described sprue is communicated with the nozzle of injection machine.
Described standing part comprises stiff end installing plate 3 and is arranged on the barrier film 4 on described stiff end installing plate 3.
The other end of described stiff end installing plate 3 is provided with locating ring 5, and described sprue 1 is located at the shaft core position of described locating ring 5.
Described movable part comprises the mobile terminal installing plate 6, movable top plate 7, partition 8, the core rod 9 that set gradually; Further, described movable top plate 7 is arranged 3 thimbles 10, described thimble 7 contacts with die cavity through described partition 8, core rod 9.
In the present invention, mobile terminal part drives movable top plate to move around, and after plastic products are shaping in die cavity, finished product can eject and come off by thimble fast.The quantity of thimble is set to 3, and one to be arranged at sprue axle center identical, and another two positional symmetry are arranged; This also further increases the speed of the demoulding.
More than show and describe general principle of the present invention and principal character and advantage of the present invention.The technical staff of the industry should understand; the present invention is not restricted to the described embodiments; what describe in above-described embodiment and description just illustrates principle of the present invention; without departing from the spirit and scope of the present invention; the present invention also has various changes and modifications, and these changes and improvements all fall in the claimed scope of the invention.Application claims protection domain is defined by appending claims and equivalent thereof.
