Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

As shown in fig. 1 to 7, the present invention provides a two-way moving front mold slide, which comprises a mold base 1, a front mold 2, a hydraulic cylinder 3 and a product body 10, wherein the front mold 2 is fixedly installed inside the mold base 1, the hydraulic cylinder 3 is fixedly installed outside the mold base 1, a cavity of the front mold 2 comprises an inverted molding cavity 9, and the inverted molding of the product body 10 is formed in the inverted molding cavity 9, the inside fixed mounting of die holder 1 has capable position base 4, the top movable mounting of capable position base 4 has slider 5 and core 7, slider 5 and pneumatic cylinder 3's piston rod fixed connection, core 7 is arranged in back-off shaping chamber 9 and cooperates the back-off of 9 shaping product bodies of back-off shaping chamber 10, the guide pillar has been seted up to the bottom of front mould 2 and has been held chamber 6, the inside fixed mounting of slider 5 has oblique guide pillar 8 and the front end part of oblique guide pillar 8 extends to the guide pillar and holds chamber 6 in, the surface in oblique guide pillar 8 is cup jointed in the activity of core 7.

The slide block 5 and the two inclined guide posts 8 do linear motion along the slide rails arranged on the slide base 4 along the extension direction of the piston rod of the hydraulic cylinder 3.

Wherein, the medial surface that two guide pillars held chamber 6 contains inclined plane and vertical face, and its shaft and front end are respectively pasting the guide pillar and hold the inboard inclined plane and the vertical face in chamber 6 when guide pillar 8 follows rectilinear motion to one side, and the guide pillar holds chamber 6 and provides the activity space for guide pillar 8 to one side, and when guide pillar 8 moved to one side and the inside that the chamber 6 was held to the guide pillar, then core 7 entered into back-off molding chamber 9 and target in place, when guide pillar 8 outwards taken out from the guide pillar when holding chamber 6 to one side, core 7 can break away from back-off molding chamber 9.

Wherein, it cup joints to be the slope between core 7 and the guide pillar 8 to one side, core 7 takes place linear motion at guide pillar 8 to one side and it can break away from or get into back-off molding cavity 9, when 8 linear motion of guide pillar to one side, because core 7 receives spacingly along 8 linear motion direction of guide pillar to one side, cause two its cores 7 can only carry out linear motion along the direction perpendicular with 8 direction of motion of guide pillar to one side, as shown in fig. 6, when the piston rod shrink of pneumatic cylinder 3, pulling slider 5 moves to the outside, cause two cores 7 to be sharp phase to each other, final core 7 can break away from back-off molding cavity 9, otherwise then can do straight line dorsad motion, final core 7 can get into back-off molding cavity 9.

Wherein, the rear module slide position corresponding to the product body 10 adopts the horizontal design.

The working principle and the using process of the utility model are as follows:

when the front mold and the rear mold are closed in place, plastic is injected into the mold cavity, after the plastic is cooled to form a product body 10, demolding is started, the inverted part of the product body 10 can be separated only by withdrawing the mold core 7 from the inverted molding cavity 9, so that the hydraulic cylinder 3 is started, the piston rod is controlled to contract, the slide block 5 and the inclined guide post 8 are pulled by the piston rod of the hydraulic cylinder 3 to synchronously move outwards, and because the inclined guide post 8 and the mold core 7 are obliquely sleeved, the inclined guide post 8 can give the motion trends of the mold core 7 towards two directions when doing linear motion, namely along the linear motion direction of the inclined guide post 8 and the opposite motion directions of the two mold cores 7, the mold core 7 is limited along the linear motion direction of the inclined guide post 8, so that the two mold cores 7 can only move towards each other, the mold core 7 can be separated from the inverted buckle of the product body 10, if the slide block 5 is pushed by the hydraulic cylinder 3, the direction of movement of the core 7 is reversed and it appears to re-enter the undercut-forming cavity 9.
