Transfer type molding machine for oversize vehicle's seals


Summary:

   XZB series transfer type molding machine for rubber(semiautomatic rubber injection molding machine) is our companys original R&D results and has a number of national patents (Patent No.ZL 03230397.3 ZL200420110566.1 and ZL200620105181.5). It is an advanced rubber pressure molding equipment with compact structure, wide applicability and high degree of automation, especially, it is suitable for producing rubber model products with metallic insert, complex shape, big cross-section and thick-wall., these products process is complex and more difficult to form. Among them the multi-purpose rubber transfer type molding machine (semiautomatic rubber injection molding machine) based on the frequency conversion technology was established as National Science and Technology Ministry innovation fund project of technology type medium and small enterprises.

Features:

   Clamping cylinder clamps mould first, then injection cylinder press rubber material into mould cavity uniformly. Therefore the rubber parts have precision dimension, uniform and stable performances.
   It uses the original imported high pressure pump, and middle and high pressure vane pump combination, controlled by proportional pressure & flow composite valve, hydraulic system configuration is advanced, reasonable and reliable with low noise and low energy consumption.
   The main moving platen raises rapidly, clamps slowly, declines rapidly, so the  efficiency is improved and the mould is protected
   It uses automatic in-out mould and ejector mechanism, reduces labor intensity and avoids the artificial damage to mould
   The hydraulic cylinder uses patent technology of oil cylinder composite sealing device (Patent No.ZL03220060.3)which is with independent intellectual property rights, with reliable seal and long service life
   The oil tank adopts the patent technology of turn board structure open tank(Patent No.ZL200620105181.5), it saves time and effort for maintenance , more human-friendly.
   The electric system adopts full computer control, it is convenient for operation. It has two working modes of point moving and semi automation. Users can choose PLC control and 5.7-inch touch-control screen imported from Siemens or Mitsubishi
    Preparing material is simple, fast. Production efficiency is high.
