Abstract
The utility model discloses a longitudinal circulation cold runner for a plastic extrusion die, which comprises a forming die, wherein a cavity is arranged in the middle of the forming die; a plurality of cooling water runners are arranged in the die above the cavity; a water inlet is formed in a side wall of the forming die the water inlet is communicated with the cooling water runners in the die; and the cooling water runners are communicated pairwise in series by gutters to form a single water flow channel. The runner ensures uniform water flow rates and flows of cooling water holes, and a coincident cooling effect.
Description
Technical field
The utility model relates to a kind of plastics extrusion die cold runner that vertically circulates.
Background technology
In the extrusion molding process, the main effect of stock mould, the molten parison that to from die head, extrude exactly, through vacuum suction, making it be close to die cavity table wall, is medium by the cooling water that flows of arranging on the die cavity, in the mode of heat exchange again, cooling, the molten base of curing obtain qualified article shape.At present, on the arrangement mode of stock mould die cavity cooling water, owing to the difference of each die casting producer at various factors such as design concept, stock mould length, process equipment, processing technologys, the arrangement mode of cooling water also is not quite similar.Existing, the arrangement mode of typing cooling water, mainly contain following two kinds: (1) leads directly to the water route; (2) " S " circulation waterway.But all there is deficiency separately in these two kinds of water routes:
1. lead directly to the water route.The general mode of concentrating turnover that adopts, this mode causes each cooling water channel easily, flow velocity, mass flow discrepancy, thus cause the cooling of section bar irregular;
2. lead directly to the water route.Section bar by cooling irregular and produce crooked, when defective such as trembling, being not easy to judge specifically is that viscous flow or stagnant water phenomenon have taken place which cooling water hole;
3. " S " circulation waterway.The water hole of processing participation circulation is more, and workload is big, and the production cycle is long;
4. " S " circulation waterway.Die cavity is required harshness, and profile must be convenient to the processing in straight-through water route, thereby has limited the range of application in this water route greatly.
The utility model content
The utility model provides a kind of vertical recirculated water mode of singly going out singly advanced, and guarantees that each cooling water hole flow rate of water flow, flow are even, the cooling effect unanimity.
The utility model technical solution problem provides following scheme:
A kind of plastics extrusion die cold runner that vertically circulates, comprise stock mould, it is characterized in that: the middle part of described stock mould has die cavity, be provided with multiple tracks cooling water runner in the mould of the top of described die cavity, the sidewall of described shaper is provided with water inlet, described water inlet is communicated with inner multiple tracks cooling water runner, gangs up in twos by gutter between the described multiple tracks cooling water runner, forms a unique flow passage.
The sidewall of stock mould is provided with a plurality of locating holes.
The loop direction in the utility model water route is parallel to extrudes direction.With each cooling water hole of stock mould end face, by milling the mode of tank, adjacent cooling water hole is ganged up in twos, form an independence, unique flow passage, thereby the cooling water that guarantee to flow can only be with an independence, unique flow path each water hole of flowing through, avoided the phenomenon of scurrying, remain in a standstill of current between the water hole, each water hole flow velocity, flow are even, the cooling effect unanimity.
Description of drawings
Fig. 1 is side structure schematic diagram of the present utility model.
Fig. 2 is cross-sectional view of the present utility model.
The specific embodiment
Referring to accompanying drawing, a kind of plastics extrusion die cold runner that vertically circulates, comprise stock mould 1, the middle part of described stock mould 1 has die cavity 2, is provided with multiple tracks cooling water runner 3 in the mould of the top of described die cavity 2, and the sidewall of described shaper 1 is provided with water inlet 4, described water inlet 4 is communicated with inner multiple tracks cooling water runner 3, gang up in twos by gutter 6 between the described multiple tracks cooling water runner 3, form a unique flow passage, the sidewall of stock mould 1 is provided with a plurality of locating holes 5.
Claims (2)
1. plastics extrusion die cold runner that vertically circulates, comprise stock mould, it is characterized in that: the middle part of described stock mould has die cavity, be provided with multiple tracks cooling water runner in the mould of the top of described die cavity, the sidewall of described shaper is provided with water inlet, described water inlet is communicated with inner multiple tracks cooling water runner, gangs up in twos by gutter between the described multiple tracks cooling water runner, forms a unique flow passage.
2. according to the described plastics extrusion die of claim 1 cold runner that vertically circulates, it is characterized in that: the sidewall of stock mould is provided with a plurality of locating holes.
