Description

Induction mold closing device

Technical Field

The utility model relates to a former technical field refers in particular to an induction mold closing device.

Background

The system cup machine adopts pneumatic cylinder elevating system or cam crankshaft to realize the lift drive of lower mould platform usually, and current cam mechanism generally need constantly rotate to drive the bent axle and push up lower mould platform, produce the driving force through the moment of torsion, though the holding power is stronger, nevertheless produce the shake easily, be unfavorable for the stability of compound die, and it is too low then efficiency to adopt the pneumatic cylinder to push up lower mould platform on the pure, can't satisfy the demand of high-efficient production.

Disclosure of Invention

An object of the utility model is to prior art current situation, provide an induction mold closing device, can realize stable quick transmission, combine adjustable stroke response, improve product application scope, improve production efficiency.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides an induction mold closing device, mainly has last mould platform and lower mould platform to and the frame, it is driven by the hydro-cylinder to go up the mould platform, and the frame is connected through the crank arm of two symmetric distributions to the lower mould platform, the frame is equipped with the pneumatic cylinder in the centre, and the cross connecting rod of pneumatic cylinder top passes through the extensible member and links with crank arm, cross connecting rod one side is connected with the stroke tablet that the level set up, and frame one side is provided with the spacing groove, and stroke tablet tip passes the spacing groove.

In the above scheme, the crank arm is composed of an upper movable arm and a lower movable arm, and the two sides of the telescopic part are telescopic arms connected with the lower movable arm.

Furthermore, the limiting groove is long-strip-shaped, and the stroke sensing plate is provided with a deep groove ball bearing and is movably connected with the limiting groove.

Furthermore, guide posts are arranged on the periphery of the machine base, and the upper die table and the lower die table move up and down under the limitation of the guide posts.

Furthermore, a guide rod is arranged on the machine base and penetrates through the cross connecting rod to be used for guiding the pipe.

The utility model has the advantages that: the butterfly-type crank arm is adopted to realize upgrading linkage, and is different from a driving structure of a lower die of a traditional cup making machine, so that the cup making machine has strong supporting force and keeps stable action; go up the mould platform by cylinder drive, the lower mould platform is by pneumatic cylinder drive, not only can adapt to the drive power demand of last lower mould platform, and effectively reduce equipment cost. The adjustable stroke induction plate is combined, so that the stroke of the lower die can be adjusted according to products of different specifications, and the application range of the products is widened.

Description of the drawings:

FIG. 1 is a schematic structural view of the present invention;

fig. 2 is a cross-sectional view of the present invention.

The specific implementation mode is as follows:

referring to fig. 1 and 2, the structure of the induction mold clamping apparatus according to the preferred embodiment of the present invention is schematically shown, the induction mold clamping apparatus of the present invention mainly includes an upper mold platen 1, a lower mold platen 2, and a base 3, wherein guide pillars 31 are disposed around the base 3, and the upper mold platen 1 and the lower mold platen 2 move up and down under the restriction of the guide pillars 31.

The upper die table 1 is driven by an oil cylinder 11, the lower die table 2 is connected with the machine base 3 through two symmetrically distributed crank arms 4, each crank arm 4 consists of an upper movable arm 41 and a lower movable arm 42, the two symmetrical crank arms 4 are similar to butterfly wings, a hydraulic cylinder 5 is arranged in the center of the machine base 3, a cross connecting rod 51 above the hydraulic cylinder 5 is linked with the crank arms 4 through a telescopic piece 6, telescopic arms 61 are arranged on two sides of the telescopic piece 6, and the telescopic arms 61 are connected with the lower movable arms 42. When the hydraulic cylinder 5 pushes the cross connecting rod 51 to ascend, the telescopic part 6 moves upwards to enable the two telescopic arms 61 to expand towards the side surfaces, so that the lower movable arm 42 is pushed to swing upwards, and because the other end of the upper movable arm 41 is limited at the bottom of the lower die table 2, the lower movable arm 42 swings upwards to push the upper movable arm 41, the included angle between the upper movable arm and the lower movable arm is increased, and the lower die table 2 is pushed to move upwards.

When the transmission of moment is realized to extensible member 6 and crank arm 4, the stroke of further meeting optimization pneumatic cylinder 5 makes pneumatic cylinder 5 under the state of small-distance removal, realizes the big distance lift of lower mould platform 2, and this process not only can improve transmission efficiency, and more stable, and this drive structure is small, can reduce the volume of equipment.

Cross connecting rod 51 one side is connected with stroke tablet 7 that the level set up, stroke tablet 7 goes up and down along with cross connecting rod 51, through the conversion, can know the lift stroke of lower mould platform 2, frame 3 one side is provided with spacing groove 8, spacing groove 8 is passed to stroke tablet 7 tip, spacing groove 8 is rectangular form, the length of this spacing groove 8 is 2 biggest lift strokes of lower mould platform promptly, be equipped with deep groove ball bearing and 8 swing joint of spacing groove through stroke tablet 7, stroke tablet 7 passes through deep groove ball bearing and moves about in spacing groove 8, spacing groove 8 is stretched out to its tip.

The guide rod 32 arranged on the machine base 3 penetrates through the cross connecting rod 51 to be used for pipe alignment guide, so that transmission of all parts is more stable, the guide rod 32 and the guide pillar 31 realize alignment of an inner pipe and an outer pipe, and the whole machine is stable in up-down lifting.

Adjustable travel switches can be arranged above and below the end part of the travel sensing plate 7, and the distance of the travel switches can be adjusted according to products to be produced, so that the telescopic range of the telescopic piece 6 is limited, and the lower die table 2 can be lifted according to the set range. In another mode, a photoelectric distance sensor can be in inductive linkage with the stroke sensing plate 7, the moving path of the stroke sensing plate 7 is fed back in time, and the system can control the hydraulic cylinder 5 to be opened and closed according to feedback information.

Of course, the above illustration is only a preferred embodiment of the present invention, and the scope of the present invention is not limited thereto, so all equivalent changes made in the principle of the present invention should be included in the protection scope of the present invention.
