Abstract
The utility model discloses a non-electric heating structure of an extrusion die head, which comprises an upper die body and a lower die body, wherein a plurality of fluid channels are arranged on thedie bodies, connecting rods used for connecting end plugs are arranged on the fluid channels, a plurality of pipe connectors are configured on the fluid channels to divide the fluid channels into a plurality of zones, each zone is heated through fluid medium, and the temperature of the fluid medium is accurately controlled through a die temperature controller. Therefore, accurate control over temperature of each zone on the die head can be realized, and the temperature field is uniform.
Description
Technical field
The utility model relates to a kind of die head device that is used to produce the extrusion moulding equipment of plastic plate, film, refers in particular to non-electric heating device.
Background technology
Present used extrusion die head mould body heating is the electrical heating form, the temperature of the difficult to a certain extent accurately control die head of this kind mode of heating, and variations in temperature is beated greatly, is unfavorable for the production of the product that temperature control is had relatively high expectations relatively.
The utility model content
Be directed to the defective that exists in the technique scheme, the purpose of this utility model is to provide a kind of extrusion die of extrusion moulding equipment, and the mode that this die head adopts the fluid media (medium) heating can realize that the temperature in die head Shang Ge district is accurately controlled, and the temperature field is even.
Above-mentioned purpose is achieved by the following technical solution:
The non-electric heating device of extrusion die includes upper and lower die body, it is characterized in that: have a plurality of fluid passages on die body, runner is provided with the connecting rod that is used for connecting plug, disposes a plurality of groups of pipe joints on the runner fluid passage is divided into several region.
Have most of spatial joint clearance between described connecting rod and the fluid passage, be convenient to fluid media (medium) and pass through, each district of fluid passage all has fluid to be advanced joint and goes out joint, forms one and independently circulates in the district.
The temperature of described fluid media (medium) is accurately controlled by the mould temperature controller, and fluid media (medium) can be oil or water.
Adopt the non-electric heating device of extrusion die of said structure, this die head adopts the mode of fluid media (medium) heating, the some heating subregions of design on die body, every district is heated by fluid media (medium), the temperature of fluid media (medium) is accurately controlled by the mould temperature controller, such mode can realize that the temperature in die head Shang Ge district accurately controls, and the temperature field is even.
Description of drawings
Fig. 1 is a STRUCTURE DECOMPOSITION schematic diagram of the present utility model;
Fig. 2 is a profile of the present utility model.
The specific embodiment
As shown in Figure 1, 2, the non-electric heating device of extrusion die, include upper die body 1, lower mold body 2, having fluid passage 3 on the die body up and down, runner 3 is provided with the connecting rod 5 that is used for connecting plug 4, dispose a plurality of groups of pipe joints 6 on the runner 3 fluid passage is divided into several region, connecting rod 5 two ends ports carry out fixing seal by sealing screw 7.
As shown in Figure 2, plug 4 and pipe joint 6 are provided in the fluid passage 3 in the embodiment that is provided, form 3 districts, pipe joint 6 can be divided into inlet pipe joint 11 and go out pipe joint 12 according to the turnover difference of fluid, each fluid passage, district all has fluid inlet tube joint 11 and goes out joint 12, has most of spatial joint clearance between connecting rod 5 and the fluid passage 3, being convenient to fluid media (medium) passes through, each district is an independently interior circulation in district, advance to walk along runner after joint 11 enters from fluid, the flow direction of plug 4 pilot fluid, and then through going out joint 12 outflows.The temperature of described fluid media (medium) is accurately controlled by the mould temperature controller, and fluid media (medium) can be oil or water.
Claims (3)
