Description
Technical Field
[0001] The utility model relates to a mold structure for preventing a front mold oil cylinder slide from being pressed and retreating, belonging to the technical field of front mold oil cylinder slides. Background Art
[0002] Injection molds generally consist of two parts: a movable mold and a fixed mold (or a punch and a die). When separated, the workpiece is taken out, and when closed, the blank is injected into the mold cavity to form the mold. In industrial production, various molds and tools are used to obtain the required products by injection molding, blow molding, extrusion, die casting or forging, smelting, stamping and other methods.
[0003] There are still some problems in the use of existing molds. During the operation of the mold, due to the poor stability of the merger between the rear mold and the front mold, it can only be squeezed by the cylinder. Due to the inaccuracy of the cylinder extraction, the slide often retreats under the action of the injection pressure, resulting in defects such as excess glue, beryllium edge, and flash on the product, resulting in poor quality of mold production. Utility Model Content
[0004] The purpose of the present utility model is to provide a mold structure that prevents the slide of the front mold cylinder from being pressed and retreating. The utility model has a simple structure and is easy to use. It can improve the stability of the merging between the rear mold and the front mold, avoid relying solely on the cylinder for extrusion, which causes the slide to retreat under the action of injection pressure, so as to solve the problems raised in the above-mentioned background technology.

The front mold is slidably connected to the surface of the processing table, and connecting plates are symmetrically installed on the surface of the processing table. Sliding rods are installed on both sides of the front mold, and the surface of the connecting plate is provided with an arc groove adapted to the sliding rod. The sliding rod is clamped in the arc groove provided on the surface of the connecting plate. A fixed plate is installed on one side surface of the connecting plate, and a movable rod is rotatably connected between the two fixed plates. The surface of the movable rod is provided with a special-shaped rocker plate, and the surface of the special-shaped rocker plate is provided with a limiting plate.

[0008] Furthermore, a limit rod is slidably connected in the through hole opened on the surface of the slider, and both ends of the limit rod pass through the slider and are installed in the sliding groove opened on the surface of the special-shaped rocker.
[0009] Furthermore, a stabilizing disk is installed on the surface of the movable rod, and a torsion spring is sleeved on the surface of the movable rod, one end of the torsion spring is connected to the stabilizing disk, and the other end of the torsion spring is connected to the fixing plate.
[0010] Furthermore, the limiting plate is adapted to the arc-shaped groove provided on the surface of the connecting plate.
[0011] Furthermore, baffles are slidably connected in the sliding grooves symmetrically opened on the surface of the connecting plate, damping strips are symmetrically installed on the surface of the baffles, and adjustment grooves matching the damping strips are opened on the surface of the connecting plate, and the damping strips are slidably connected to the adjustment grooves opened on the surface of the connecting plate.
[0012] Furthermore, the damping strip is used to stabilize the position of the baffle.

When the two baffles contact each other, the two baffles fix the position of the limit plate to avoid position displacement during use. The resistance of the damping strip can stabilize the position of the baffle. BRIEF DESCRIPTION OF THE DRAWINGS
