Abstract
The invention discloses a cold feed rubber extruder head. Each flow channel area comprises a horizontal channel, a first longitudinal channel, two first inclined channels, second longitudinal channels, two second inclined channels, third longitudinal channels and a circular channel, wherein the first longitudinal channel is perpendicular to the horizontal channel, the two first inclined channels are formed in the tail end of the first longitudinal channel, the second longitudinal channels are formed in the tail ends of the first inclined channels, the two second inclined channels are formed in the tail ends of the second longitudinal channels, the third longitudinal channels are formed in the tail ends of the second inclined channels, the circular channel is used for connecting all the third longitudinal channels, and both side walls of each of the first longitudinal channel, the first inclined channels, the second longitudinal channels, the second inclined channels and the third longitudinal channels are straight walls. The cold feed rubber extruder head has the advantages that the whole flow channel network is gradually divided into eight longitudinal channels to enter the circular channel at last, additionally, the side walls of the longitudinal channels and the inclined channels are set into the straight walls, and in the process that rubber fluid enters the inclined channels from the multistage longitudinal channels, the fluid quantity of the two inclined channels is uniform, so that the rubber fluid which enters the circular channel is uniform.
Description
Technical field
The present invention relates to a kind of rubber-moulding apparatus field, especially relate to a kind of cold feed rubber machine head.
Background technology
The head of Rubber Extruder is rubber extrusion forming equipment, and raw material is extruded forward in the runner of head, and by given shape mouth mould as Jiao Kou, extrusion molding.Traditional cross-head comprises casing and movement, the outer annular surface of movement is provided with for the mobile notch of rubber fluid, casing is set in the outer rear fluid passage that forms of movement, one side of casing is provided with rubber and clamp-ons mouth, rubber is clamp-oned and mouthful is bordered on and be communicated with fluid passage, and the initiating terminal of fluid passage is positioned at a side of movement rear end, is then divided into two-way, by two-way, be divided into four tunnels again, Si Lu branch runner is uniformly distributed in the front end of movement; In traditional runner design, better in order to consider the mobility of fluid rubber, runners all in existing design adopt the smooth transition of circular arc.Although each waits the bore of runner is same, because rubber fluid exists pressure and flow velocity when entering runner, rubber fluid is when shunting, to the flow of flow tendency direction multiple spot more, the sebific duct meeting became uneven of last moulding.
Summary of the invention
Technical problem to be solved by this invention is to provide a kind of fluid distribution cold feed rubber machine head more uniformly.
The present invention solves the problems of the technologies described above adopted technical scheme: a kind of cold feed rubber machine head, comprise casing and movement, between described casing and movement, be provided with network of fluid passages, it is characterized in that described network of fluid passages comprises two flow channel area that structure is identical, two flow channel area are symmetrically distributed in the periphery of movement, each flow channel area comprises interconnection, first vertical passage vertical with interconnection, two the first slanted channels that the first vertical passage end arranges, the end of the first slanted channel is provided with the second vertical passage, two the second slanted channels that the second vertical passage end arranges, the 3rd vertical passage and the circular passage that is connected all the 3rd vertical passages that the second slanted channel end arranges, the first described vertical passage, the first slanted channel, the second vertical passage, the second slanted channel, the two side of the 3rd vertical passage is straight wall.
Between circular passage and the 3rd vertical passage, be provided with transition passage, the two side of described transition passage is straight wall.
Included angle A between two described the first slanted channels is 110 degree～130 degree, and the included angle B between two described the second slanted channels is 110 degree～130 degree.
Described included angle A and included angle B are all 120 degree.
Compared with prior art, advantage of the present invention is that whole network of fluid passages is divided into gradually 8 last vertical passages and enters in circular passage, rubber fluid well-distributing in last circular passage is wrapped in sebific duct tube core, the distribution of rubber fluid is uniformly dispersed more, the sidewall of vertical passage and slanted channel is all arranged to straight wall simultaneously, rubber fluid enters into slanted channel process by multistage vertical passage, the Fluid Volume of two slanted channels is more even, and the rubber fluid that further makes to enter into circular passage is more even.

The specific embodiment
Below in conjunction with accompanying drawing, embodiment is described in further detail the present invention.
A kind of cold feed rubber machine head, comprise casing 1 and movement 2, between casing 1 and movement 2, be provided with network of fluid passages 3, network of fluid passages 3 comprises two flow channel area 4 that structure is identical, two flow channel area 4 are symmetrically distributed in the periphery of movement 2, each flow channel area 4 comprises interconnection 41, first vertical passage 42 vertical with interconnection, two the first slanted channels 44 that the first vertical passage 42 ends arrange, the end of the first slanted channel 44 is provided with the second vertical passage 45, two the second slanted channels 46 that the second vertical passage 45 ends arrange, the 3rd vertical passage 47 and the circular passage 48 that is connected all the 3rd vertical passages 47 that the second slanted channel 46 ends arrange, the first vertical passage 42, the first slanted channel 44, the second vertical passage 45, the second slanted channel 46, the two side 5 of the 3rd vertical passage 47 is all straight wall.
Between circular passage 47 and the 3rd vertical passage 47, be provided with transition passage 48, the two side 6 of transition passage 48 is straight wall.
Included angle A between two the first slanted channels 44 be 110 degree or 120 degree or 130 degree, the included angle B between two the second slanted channels 46 be 110 degree or 120 degree or 130 degree, the included angle A on same movement with the angle of included angle B for equating.
