Angle Pin 274 is located in a side that forms limiting section 271a on slide block positioning seat 271, and part is exposed outside slide block positioning seat 271.
Slide block 273 is T-shaped, and on slide block 273, offers and the exposed inclined guide groove 273a matching in the part in slide block positioning seat 271 outsides of Angle Pin 274.Therefore, in the time of mould matched moulds, the Angle Pin 274 that runs through slide block positioning seat 271 is further inserted in inclined guide groove 273a, and the contact-making surface of slide block 273 is resisted against on the limiting section 271a of slide block positioning seat 271.
Two SLIDE GUIDEs 275 are oppositely arranged on the both sides of slide block 273, and two SLIDE GUIDEs 275 are separately fixed on solid plate 217 by the second fixture 276 separately.Slide block 273 is spacing between two SLIDE GUIDEs 275, and along the plane between two SLIDE GUIDEs 275 slidably.Preferably, first, second fixture is fixed screw or set bolt.
In the time that dynamic model assembly 22 moves along the direction (towards the direction away from cover half assembly 21) of die sinking, drive moving platen 222 and the slide block positioning seat 271 and the Angle Pin 274 that are fixed on moving platen 222 move along die sinking direction; Now, along with detaching of Angle Pin 274, the plane axial and that two SLIDE GUIDEs 275 of fitting limit along Angle Pin 274 moves slide block 273, thereby makes slide block 274 depart from the side opening of product.
Preferably, in the utility model one specific embodiment, when the utility model is during for the manufacture of carbon fibre composite notebook computer casing, because product has more back-off or side opening structure, therefore this mould has adopted 29 Slanted ejecting components and 2 slide block assemblies.
Briefly introduce the moulding that adopts injection mold of the present utility model and the process of preparing the plastic products of carbon fibre composite below in conjunction with Fig. 1-8.
In the time of matched moulds state, inject the carbon fibre composite of melting from sprue bush 241, under specific technological parameter, complete injection moulding, pressurize and cooling, thereby complete the forming process of plastic products.
In the time of die opening state, dynamic model assembly 22, under the drive of injection machine, towards moving away from the direction of cover half assembly 21, and drives sliding part 232 to move to the end of deduction 231 along chute.Subsequently, when dynamic model assembly 22 continues when mobile, be fixedly connected with deduction fixture 233 eject base plate 214 under the drive of deduction 231 along with dynamic model assembly 22 is similarly towards moving away from the direction of cover half assembly 22.Now, the mobile base plate 214 that ejects drives retaining plate 215 to move, and then drive inclined top guide block 262 along moving away from the direction of cover half assembly 21, and oblique top 261 moves (moving to right along the level in Fig. 6) along the gathering sill on inclined top guide block 262, thus the back-off structure of disengaging product.
Meanwhile, moving platen 222 and be fixed on slide block positioning seat 271 on moving platen 222 and Angle Pin 274 along moving away from the direction of cover half assembly 21.Now, along with detaching of Angle Pin 274, the plane axial and that two SLIDE GUIDEs 275 of fitting limit along Angle Pin 274 moves slide block 273, thereby makes slide block 274 depart from the side opening of product.
Finally, eject carbon fibre composite plastic products by thimble 25, complete its injection molding process.
Below mould and the forming process thereof of carbon fibre composite notebook computer casing have only been provided.But, should be understood that, above-mentioned mould also can be applied in the carbon fibre composite plastic products of manufacturing other structures.And the impact that the quality that adopts this kind of mould can effectively reduce the bad plastic products that moulding is obtained of the mobility of carbon fibre composite own causes, improves the quality of the plastic products of producing, and improves its production efficiency.
In the mould of carbon fibre composite plastic products of the present utility model, by the mode that adopts Multi-spot pouring, carbon fibre composite is carried out to injection mo(u)lding to obtain plastic products, and adopt the mode of twice-die-opening to carry out the demoulding to plastic products, make it possible to produce the measured carbon fibre composite plastic products of matter; In addition, because this mould has the ejecting mechanism that includes oblique top and slide block, make can successfully from the structure such as back-off and side opening of plastic products, depart from knockout course, improved production efficiency and the Forming Quality of product.Because adopting carbon fibre composite, the utility model carries out injection moulding as raw material, can effectively reduce the thickness of obtained plastic products, and alleviate its weight, and prepared plastic products have good electromagnetic wave shielding, and higher intensity, be specially adapted to manufacture notebook computer casing, and can meet the demand of consumer to notebook computer casing.
