Abstract
The utility model relates to an extrusion molding mold for plastic profiles used in refrigerators, and solves the problems of the prior extrusion molding mold for plastic profiles that the production efficiency is low, and the production cost is high. The mold comprises an upper cavity plate and a lower cavity plate, wherein, vacuum cover boards are arranged on the outer surfaces of the upper cavity plate and the lower cavity plate respectively; vacuum joints are arranged on the vacuum cover boards; and cooling water nozzles are formed on the outer side surfaces of the upper cavity plate and the lower cavity plate respectively. The mold is characterized in that two parallel profile stripe cavities are formed between the opposite surfaces of the upper cavity plate and the lower cavity plate. The utility model increases the productivities to when in production with raw material which is polystyrene plastic (PS plastic), the mold can extrude 300 strips (4,000 mm/strip) per 8 hours; when in production with raw material which is acrylonitrile-butadiene-styrene copolymer (ABS plastic), the mold can extrude 350 strips (4,300mm/strip) per 8 hours. Therefore, the utility model has the advantages that the production efficiency is improved; the product quality can also meet the technical requirements; and the production cost is reduced.
Description
Technical field
The utility model relates to the plastic material extrusion die, specifically refrigerator plastic material extrusion die.
Background technology
Existing refrigerator has only a die cavity with the plastic material extrusion die, when being used for raw material and being polystyrene plastics (PS plastics) and producing, extrudes in 8 hours 160 rectangular (4000mm/ root); When being used for raw material and being acrylonitrile-butadiene-styrene copolymer plastics (ABS plastic) and producing, extruded 200 rectangular (4300mm/ root) in 8 hours, production efficiency is lower, the production cost height.
Summary of the invention
In order to reduce production costs, to enhance productivity, the utility model provides a kind of new refrigerator plastic material extrusion die.
The technical scheme that realizes above-mentioned purpose is as follows:
Refrigerator comprises upper cavity plate and lower mode cavity plate with plastic material extrusioning shaping mould, form die cavity between corresponding of upper cavity plate and the lower mode cavity plate, upper cavity plate and lower mode cavity plate outer surface are respectively equipped with the vacuum cover plate, the vacuum cover plate is provided with vacuum adapter, the lateral surface of upper cavity plate and lower mode cavity plate is respectively equipped with the cooling water water nozzle, and its improvement is:
Be provided with two parallel strip section die cavitys between corresponding of described upper cavity plate and the lower mode cavity plate.
The utility model is provided with two die cavitys by to the improvement of existing mold on mould, production capacity increases to: when being used for raw material and being polystyrene plastics (PS plastics) and producing, extruded in 8 hours 300 rectangular (4000mm/ root); When being used for raw material and being acrylonitrile-butadiene-styrene copolymer plastics (ABS plastic) and producing, extruded in 8 hours 350 rectangular (4300mm/ root); Improved production efficiency.
Cost compares: if adopt the Technological improvement plan that increases equipment and mold, need input: yuan (mould)=110,000,80,000 yuan of (equipment)+30,000; If adopt the utility model mould, do not increase device just and drop into the mould improvement cost: 3.4 ten thousand (equipment is constant), reduced production cost.
The utility model mould and the supporting use of die head with two chambers, its external dimensions is bigger by 1/2nd than original stock mould, but still can with the supporting use of original equipment, the former stock mould of productivity ratio increases more than 3/4ths, product quality satisfies specification requirement equally, saved equipment, the electricity charge, raised labour efficiency.
Description of drawings
Fig. 1 is the utility model structural representation,
Fig. 2 is the A-A cutaway view of Fig. 1.
The specific embodiment
Below in conjunction with accompanying drawing, the utility model is further described by embodiment.
Embodiment:
Referring to Fig. 1, Fig. 2, refrigerator comprises upper cavity plate 4 and lower mode cavity plate 5 with plastic material extrusioning shaping mould, be provided with two parallel strip section die cavitys 6 between 5 corresponding of upper cavity plate 4 and the lower mode cavity plates, upper cavity plate 4 and lower mode cavity plate 5 outer surfaces are respectively equipped with vacuum cover plate 2, vacuum adapter 3 is installed on the vacuum cover plate 2, and the lateral surface of upper cavity plate 4 and lower mode cavity plate 5 is separately installed with cooling water water nozzle 1.
The utility model mould and the supporting use of die head with two chambers, the centre distance in two chambeies is consistent with the centre distance of die head two chambers, because die head has amplified 1.2 times than grand master pattern area of bed in manufacturing process, and when making stock mould, two chamber sizes of stock mould and product actual size more bigger (about 0.1mm), in order to keep die head consistent with stock mould, so the size of shaper two chamber inward flanges should be bigger 1.2 times than the size of die head two chamber inward flanges.
Claims (1)
1, refrigerator plastic material extrusioning shaping mould, comprise upper cavity plate and lower mode cavity plate, form die cavity between corresponding of upper cavity plate and the lower mode cavity plate, upper cavity plate and lower mode cavity plate outer surface are respectively equipped with the vacuum cover plate, the vacuum cover plate is provided with vacuum adapter, the lateral surface of upper cavity plate and lower mode cavity plate is respectively equipped with the cooling water water nozzle, it is characterized in that:
Be provided with two parallel strip section die cavitys between corresponding of described upper cavity plate and the lower mode cavity plate.
