Specific embodiment

Define explanation：It is in the case that pressure angle refers to not calculate frictional force, sharp folded by Impact direction and the direction of motion Angle.The impact of frictional force and component gravity and inertia in each motion is not considered, driving during mechanism kinematic suffered by driven member Angle between the velocity attitude line of the line of direction of power and the point of force application.

A kind of plating PP section bar mold heads（As shown in Fig. 1-3）, it is installed on extrusion equipment（As on extruder）, with Extrusion equipment is combined for producing plating PP section bars, folds the rear die body 11 for setting including fixing successively, the second rebound 12, and first Rebound 13, supporting plate 14, cylinder manifold 15, the second mouth mold 16 and the first mouth mold 17.Supporting plate 14 is near First Transition plate 12 Side, i.e., described 14 back side of supporting plate (left side of supporting plate 14 as shown in Figure 2) are provided with spreader 30, the spreader Bevel angle α is 64 °.

The folded rear die body 11 for setting, the second rebound 12, First Transition plate 13, supporting plate 14, cylinder manifold 15, second mouthful Mould 16 and the first mouth mold 17 are adapted to the material chamber 40 for forming that the pp material for Gong mixing pass through with the spreader 30, the material chamber 40 Shape can be arranged according to profile shapes（The section bar of the present embodiment is hexagon）, in the presence of spreader 30, the material chamber 40 The first diffluence pass 41 is provided with, first diffluence pass 41 is located in rear die body 11.Plug 50 is provided with second mouth mold 16, Plug 50 causes material chamber 40 to shunt the second diffluence pass 42, and second diffluence pass 42 is located between rebound 13 and supporting plate 14.

Relative to the second mouth mold 16, first mouth mold 17（Namely 17 front of the first mouth mold）On be provided with pre- cold water jacket 80, pre- cold water jacket 80 is used to cool down pp material.

Plating covers heater with PP section bar mold heads surface（Indicate in figure）, heater avoids passage 70 Put, passage 70, the connection plug 50 of passage 70 are set in second mouth mold 12（Passage 70 is also provided with plug 50）.Wherein, 50 length of plug is higher than plating PP section bar mold head whole heights（Plug 50 projects plating and is set with PP section bar mold heads Put）, it is easy to product moulding and helps cooling.

Using method of the present utility model is：Rear die body 10 is connected to into extrusion equipment（Indicate in figure）On, plus Hot device is covered in die surface and is warmed to design temperature.Heater will avoid hole site of ventilating when installing.While pre- cold water jacket Add water to form Water-cooling circulating.After extrusion equipment is entered, in die body 10, pp material are divided the pp material for mixing by the first diffluence pass of Jing 41 Stream, sequentially passes through the second rebound 12 and First Transition plate 13, and pp is expected in 12 pressure angle of First Transition plate 13 and the second rebound （Due to shunting）In the presence of expect in chamber 40, to form pressure, supporting plate 14 is uniformly flowed to by spreader 30, in supporting plate 14 Form second diffluence（Through the second diffluence pass 42）, cylinder manifold 15 is flowed to, and PP streams is made under the pressure angle effect of cylinder manifold 15 Dynamic property is more uniform, and PP material obtain the pre- shape of product for needing by plug 50 and the second mouth mold 16, the shaped segment of the first mouth mold 17 State is extruded from the first mouth mold 17；Finally, the product form and chi of final needs under the cooling effect of pre- cold water jacket 80, are obtained It is very little.

Assembling mode of the present utility model is as follows：

Die body 11 is connected on extrusion equipment afterwards；Die body 11 is fixed on the second mistake with 12.9 grade high-strength hexagon socket head cap screws afterwards On cab apron 12；Second rebound 12 is fixed on First Transition plate 11 with 12.9 grade high-strength hexagon socket head cap screws；Spreader 30 is adopted It is fixed on 14 back side of supporting plate (left side of supporting plate 14 as shown in Figure 2) with 12.9 grade high-strength hexagon socket head cap screws；Plug 50 are threadedly secured to 16 front of the second mouth mold（Second mouth mold, 16 right side as shown in Figure 2）On；By the first mouth mold 17, second Mouth mold 16, cylinder manifold 15, supporting plate 14 are fixed on First Transition plate 13 with 12.9 grade high-strength hexagon socket head cap screws；Pre- cold water jacket 80 are fixed on 17 front of the first mouth mold using 12.9 grade high-strength hexagon socket head cap screws（First mouth mold, 17 right side as shown in Figure 2） On；Mould parts（Such as rear die body 11, the second rebound 12, First Transition plate 13, supporting plate 14, cylinder manifold 15 etc.）Each other Must first be fixed with alignment pin.

Using the shunting material of spreader 30 chamber 40, this utility model expects that the pp in chamber 40 is expected in branching process, in the first mistake Mix homogeneously in the presence of 12 pressure angle of cab apron 13 and the second rebound；Secondly, can be according to the Adjusting Shape material chamber of section bar（First In mouth mold 17 and the second mouth mold 16）Shape, form satisfactory section bar；Additionally, also by arranging plug 50, second diffluence Material chamber so that pp is expected more towards uniform, then in the presence of pre- cold water jacket, cooling shaping mixes as pp material are uniform so that The product strength of molding is high, without precipitation, ungauged regions, and good toughness and non-aging.There is certain aesthetic property simultaneously.
