Abstract
The invention, relating to mold processing of plastic products, discloses a high-brightness plastic profile forming die. The forming die comprises three combination die sets which are successively connected, wherein, each combination die set comprises an upper cover plate and a base plate, a cavity template is arranged between the two plates, the upper cover plate and the base plate are both provided with a vacuum adsorption system and a water cooling system. The water cooling system comprises a water inlet faucet, a water outlet faucet, and a cooling waterway, characterized in that the cooling waterway of the water cooling system is a plurality S-shaped circulating waterways which are axially and successively arranged. According to the invention, the problems of non-uniform cooling on the product surfaces in plastic mold processing and unsatisfactory brightness of the product surfaces existing in the prior art are solved, and the invention can be widely applied for processing plastic door and window and other building material products and plastic household products.
Description
(1) technical field: the present invention relates to the plastic products processing mold, especially a kind of high brightness plastic material stock mould.
(2) background technology: along with plastic door-window wideling popularize in China; People's continuous intensification that processing uses section bar to be familiar with to plastic door-window; A lot of users not only are confined to satisfy instructions for use when the selection type section product, and the outward appearance of section bar product and the requirement of surface quality are also become increasingly high.Become to estimate a kind of important indicator of product quality and class as the surface brightness that influences one of products appearance quality.The surface brightness of domestic version section product is generally below 30 ° at present, and the section bar surface brightness of most producers die production is below 20 °, or the surface is the vaporific brightness that do not have.Tracing it to its cause, is cooling water channel unreasonable the causing of design owing to stock mould, and existing plastic products stock mould includes the combination die that three covers connect successively; Every cover combination die includes upper cover plate and base plate, and the die cavity template is housed between two plates, and in upper cover plate and base plate, is provided with vacuum suction system and water cooling system; Said water cooling system includes that water-in and water-out are chewed and cooling water channel, and in the prior art, water cooling system is that the straight line water route arranged by many axially parallels and water-in and water-out are chewed and constituted; This many axial straight line water route structures; Between the straight line water route spacing must be arranged, the section bar blank moves vertically aborning, so the plastic material surface cool is inhomogeneous; Surface brightness is poor, has a strong impact on the competitiveness of product in market.
The (3) summary of the invention: the object of the invention will solve in the existing plastics stock mould use even to the product surface inhomogeneous cooling exactly, and the unfavorable problem of product surface brightness provides a kind of high brightness plastic material stock mould.
Design principle of the present invention is: plastic raw materials gets into die head preformed state after equipment is heated into the section bar liquid, and the preformed shape product that comes out from die head is through the cooling of stock mould, and adsorption forming is the shape product with respective shapes and size.Contact friction through stock mould simultaneously makes goods have certain surface brightness, so mold cavity will guarantee that each face all will could guarantee brightness with the shape product even contact.The aqueous vapor road of stock mould fully guarantees the even cooling and the absorption of shape product when designing; And just make shape product and stock mould die cavity that contact friction has taken place just because of the cooling of aqueous vapor and absorption, if so the cooling of goods insufficient even, the frictional force that makes goods and die cavity is changed; Thereby cause differing of shape product surface brightness; Obviously, it is full and uniform more that shape product cools off, and the surface brightness of shape product is high more; So in the stock mould design and making, should take into full account even cooling and evenly absorption.
The present invention has proposed following scheme according to above-mentioned principle: a kind of high brightness plastic material stock mould; Include the combination die that three covers connect successively; Every cover combination die includes upper cover plate and base plate, and the die cavity template is housed between two plates, and in upper cover plate and base plate, is provided with vacuum suction system and water cooling system; Said water cooling system includes that water-in and water-out are chewed and cooling water channel, it is characterized in that: the cooling water channel in the said water cooling system is the axial S shape circulation waterway of a plurality of continuous layouts.
In order to guarantee fully cooling effect uniformly, the die cavity width in the radial width >=die cavity template of the shape of S described in the present invention circulation waterway.And the length in each S shape water route is 40 ± 3mm in the said S shape circulation waterway.
In order further to improve cooling effect, in the three cover combination dies, be to adopt rubber seal to be tightly connected between first combination die and second combination die described in the present invention, be that the hermetically sealed little water tank of employing is connected between second combination die and the 3rd combination die.
Said hermetically sealed little water tank has casing and loam cake described in the present invention, and the left end of loam cake and casing left plate adopt the stainless steel hinge to be connected, the right-hand member of loam cake corresponding with casing the right plate employing pull the hook look buckle; And on the left plate of casing, feeded water rapidly is housed and chews, on cover and fast-assembling gas is housed chews, add rubber seal O type adhesive tape between loam cake and the casing.
The present invention has changed the version of cooling water channel in the water cooling system of mould; Promptly change into S type circulation waterway by many straight line water routes arranged side by side; Improved the cooling effect and the uniformity of combination die greatly, adopted the surface of plastic products brightness of die production of the present invention high, can reach more than 45 °; Burnishing has improved competition capability greatly.
The (4) description of drawings:
Fig. 1 is a front view of the present invention;
Fig. 2 is a vertical view of the present invention;
Fig. 3 is the A-A view of Fig. 1.
Among the figure: 1-first combination die, 2-second combination die, 3-the 3rd combination die, 4-S shape circulation waterway, 5-upper cover plate, 6-die cavity template; The 7-base plate, the 8-water outlet is chewed, the hermetically sealed little water tank of 9-, the 10-rubber seal, the 11-water inlet is chewed, and the 12-vacuum suction is chewed; 13-vacuum suction pore, 14-rubber seal O type adhesive tape, 15-pulls hook, the 16-loam cake, 17 fast-assembling gas are chewed, 18-stainless steel hinge; The 19-feeded water rapidly is chewed, 20-rubber seal, 21-die cavity hole, 22-casing, 23-handle.
