Abstract
The utility model relates to a machining mold for plastic products, in particular to a high-brightness plastic profile shaping mold which is provided with three sets of sequentially connected segment molds, wherein each set of segment mold comprises an upper cover plate and a bottom plate; a cavity mold plate is arranged between the two plates; a vacuum adsorption system and a water cooling system are respectively arranged in the upper cover plate and the bottom plate; and the water cooling system comprises a water inlet nozzle, a water outlet nozzle and cooling water channels. The high-brightness plastic profile shaping mold is characterized in that the cooling water channels in the water cooling system are a plurality of axial S-shaped circulating water channels distributed continuously. The shaping mold solves the problems of non-uniform cooling to the product surface and not ideal brightness of the product surface in the machining of the conventional plastic shaping mold and can be widely used for machining building products such as plastic doors and windows and plastic daily use products.
Description
The (1) technical field: the utility model 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 purpose of the utility model 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.
The design principle of the utility model 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 utility model 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; The die cavity template is housed between two plates; And in upper cover plate and base plate, be 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 utility model 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 utility model, be that the hermetically sealed little water tank of employing is connected between second combination die and the 3rd combination die.
Hermetically sealed little water tank has casing and loam cake described in the utility model, and the left end of loam cake adopts the stainless steel hinge to be connected with the casing left plate, and the right plate that the right-hand member of loam cake is corresponding with casing adopts and pulls 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 utility model 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 the utility model die production high, can reach more than 45 °; Burnishing has improved competition capability greatly.
