Description
Technical field
The utility model is related to field of die equipment, relate in particular to a kind of injection moulding die casting mouth set.
Background technology
Injection mold is a kind of tool producing plasthetics, is also to confer to plasthetics complete structure and accurate dimension
Tool.Injection molding is to produce a kind of processing method used when certain complex-shaped components in batches, refers specifically to melt heated
Plastics by injection molding machine from sprue bush high pressure inject injection mold die cavity obtain formed products after cooling and solidifying.It is existing to pour
Muzzle design comparison tradition is merely capable of playing the role of allowing injection mold die cavity to connect with injection molding machine cast nozzle, be molded
Machine by liquid plastic inject die cavity after cooling procedure in, the plastics volume in die cavity can be gradually reduced, need constantly from
Plastics are supplemented in sprue bush to enter in die cavity.This process is constantly molded there is still a need for injection molding machine to complete at present, and sprue bush without
Method provides pressure, forces the plastics in sprue bush to enter in die cavity, leading to plastic part after injection molding, there may be defects
Risk.
Utility model content
The utility model can not only allow injection mould mainly solving the technical problems that provide a kind of injection moulding die casting mouth set
Tool die cavity is connected to injection molding machine cast nozzle, and after injection molding machine is molded, can be provided pressure and be forced in sprue bush
Plastics, which enter in die cavity, supplements the vacancy that plastics coagulated volume reduces, and sprue bush provides pressure feeding pressurize note more direct than injection molding machine
It is more advantageous to mould feeding, has ensured that the size after plastic piece shaping is complete.
To achieve the above object, the utility model provides technical solution below：
Injection moulding die casting mouth set includes cylindrical installation base and body coaxially, and the diameter of installation base is more than body
Diameter, installation base side is uniformly provided with several threaded holes, the gate end of circular arc hole shape is equipped at the center of installation base end
Hole is provided with cylindrical thin running channel at installation base inside center, and thin running channel is connected to cast gate stomidium, and cylinder is provided with inside body
The thick running channel of through hole shape, thin running channel is connected to thick running channel and coaxially, installation base side is provided with several injection pressures for leading directly to thick running channels
The installation base port position in duct, each injection pressure duct is sealedly connected with connecting tube.
As advanced optimizing for the technical program, the installation base and body are by alloy tool steel making, installation
Boss and body are overall structure.
As advanced optimizing for the technical program, the thick running channel diameter is than big 3 times of thin running channel diameter or more.
As advanced optimizing for the technical program, the connecting tube is made of stainless steel, connecting tube and installation base
It is connected through a screw thread.
It is using the advantageous effect of above technical scheme：Body can be inserted into be molded when mounted by injection moulding die casting mouth set
It allows thick running channel to be connected to injection mold die cavity in mold, is screwed in threaded hole with screw and be fastenedly connected template and installation base, so
Air compressor is connected to all connecting tubes afterwards.The injection molding tube end of injection molding machine can be inserted into cast gate stomidium when use, so
Injection molding machine after waiting for injection molding machine injection molding, is beaten by liquid plastic from the die cavity that thin running channel and thick running channel pour into injection mold afterwards
Air compressor is opened, the compressed air by entering injection pressure duct, which can provide pressure, forces the plastics in sprue bush to enter die cavity
The vacancy that middle supplement plastics coagulated volume reduces, has ensured that the size after plastic piece shaping is complete.
Description of the drawings
Specific embodiment of the present utility model is described in further detail below in conjunction with the accompanying drawings.
Fig. 1 is the structural schematic diagram of the utility model injection moulding die casting mouth set；
