The specific embodiment
For above-mentioned feature and advantage of the present utility model can be become apparent, embodiment cited below particularly, and cooperation accompanying drawing be described in detail below, but the utility model are not limited to this.
With reference to figure 1, Fig. 2, Fig. 3 and Fig. 4, a kind of rotating core-pulling mechanism of mould rubber mold, comprise mould frame and the horizontal die mandrel 1 that is used to form class tubular rubber goods, the support bar 2 at jack-up horizontal die mandrel 1 both ends from bottom to top when described mould frame is provided with the demoulding, the reverse end 3 of described horizontal die mandrel 1 stripping direction is hinged on lifting seat 4 tops of being located on the mould frame, be fixedly connected with lifting seat 4 bottoms and be integral in order to drive drive plate 5 that support bar 2 moves up and down, be provided with to order about the driving mechanism that horizontal die mandrel 1 movable end lifts on the mould frame.Reverse end is stiff end, the position of picture in picture numbers 3.
In order to be conducive to the rotation of horizontal die mandrel, described driving mechanism comprise the lifter rack 7 that driven by vertical cylinder 6 and by lifter rack drive 7 and with the horizontal die mandrel 1 hinged pin-and-hole 8 coaxial driven gears 9 that rotate that connect.
For horizontal die mandrel and driven gear rotate simultaneously, described horizontal die mandrel 1 passes fuse contiguous block 10, form coaxial the connection with driven gear 9 and bearing 11 by rotating shaft 12, described fuse contiguous block is the tubular cylinder that end face and periphery through hole are cross-hole.
For the installation and removal of easy of rise tooth bar, described lifter rack 7 right-hand members are provided with the groove that matches with the T-shaped groove of guide pad, and described guide pad is fixed in lifting seat 4 tops after lifter rack 7 and driven gear 9 are joined work.
For the assembling of easy of rise tooth bar and cylinder, described vertical cylinder 6 is fixed in lifting seat 4 bottoms, and cylinder 6 push rods 14 heads are provided with the groove that matches with the T-shaped groove in lifter rack 7 lower ends.
Described support bar lower end is fixed on the support panel 15.
In order to determine can to reset smoothly after drive plate movement travel and the motion, described support panel is provided with reset guide rod 16 and limited block 17, and described support panel 15 is fixed on 5 of the drive plates, drives support bar 2 when being beneficial to drive plate 5 motion and moves up and down.
The course of work of the present utility model is as follows: after die casting is finished and formed rubber, carry out the die sinking action, cover half moves upward, and utilizes the flexibility of rubber, and rubber breaks away from from upper impression by force.Drive plate moves under the thrust of casting machine, and it is up to drive support bar, and is up with auxiliary horizontal die mandrel, and rubber is broken away from from lower impressions by force.When plate to be driven moves to the position that is beneficial to the rubber taking-up, the air cylinder driven push rod stretches downwards, move downward to drive lifter rack, thereby driving driven gear turns clockwise, drive the horizontal die mandrel rotation of coaxial connection, horizontal die mandrel movable end is raised to the angle that is beneficial to the demoulding, aims at rubber with air gun again, make rubber break away from the horizontal die mandrel, finish the demoulding of rubber.During matched moulds, the horizontal die mandrel contacts with support bar, recovers horizontal state, lower descending along with drive plate about spring, and then the descending lid of patrix contacts with counterdie, recovery mould original state.
