Two-platen injection molding machine with withdrawable tie rod

Abstract

The invention discloses a two-plate-type injection molding machine with drawable pull rods. The two-plate-type injection molding machine comprises a fixed mold plate, a movable mold plate and the pull rods, wherein the fixed mold plate and the movable mold plate are connected by an upper pull rod and a lower pull rod; the upper pull rod and the lower pull rod are provided with a band-type brake mechanism at the extending end of the movable mold plate; the tail ends of the upper pull rod and the lower pull rod are provided with lock mold oil cylinders; the upper pull rod is a drawable pull rod; the fixed mold plate is provided with a support; support plates are fixed on the lock mold oil cylinders; the bottom surfaces of the support plates and the support are provided with a guide mechanism and a reciprocating driving mechanism; the reciprocating driving mechanism is connected with the support and the support plates; when the reciprocating driving mechanism drives toward one direction, the support plates and the drawable pull rods are driven to leave away from the movable mold plate; when the reciprocating driving mechanism drives toward the opposite direction, the support plates and the drawable pull rods are driven to be close to the movable mold plate, and the drawable pull rods reset. The two-plate-type injection molding machine with the drawable pull rods can lower the requirements on plants and hoisting equipment, allows a mold to be replaced much conveniently, reduces the cost, and can be adaptive to the installation environment well.

Description

Technical field [0001] The invention relates to an injection molding machine, in particular to a two-platen injection molding machine. Background technique [0002] The existing two-platen injection molding machine generally uses four tie rods to be fixed relative to the fixed template. When the mold is installed and replaced, the mold needs to be lifted and higher than the tie rod by a lifting device, and the mold is hoisted from the top of the machine to be fixed in the injection molding machine. Inside the machine, such as figure 1 Shown. The mold installation of this two-platen injection molding machine has higher requirements for the height of the workshop and lifting equipment, especially for the large two-platen injection molding machine, the mold installation is more difficult. [0003] Injection molding equipment molds generally use a crane to lift the mold above the upper edge of the upper tie rod, and then hoist the mold into the injection molding machine. Due to the h...
