Description
Technical field
The present invention relates to a kind of hot forming tool, relate in particular to a kind of hot forming tool that is specially adapted to the processing of back-off container.
Background technology
In people's life, can see or use various plastic products, for example cup, dish, food disc, toy, skullcap, and automobile component, building decoration spare, chemical industry equipment etc., plastic processing is produced and is comprised injection mo(u)lding and thermoforming, for example cup, dish, food disc, toy, skullcap, and automobile component, building decoration spare, chemical industry equipment etc.
The thermoforming machine of existing production plastic containers usually adopts push rod after matched molds punching shear, from the bottom of container it is ejected die cavity.
Yet, goods for the contour structures complexity, especially outer wall or outer wall marginal belt have the back-off that caves inward or the container of other labyrinths such as spiral buckle, adopt existing mode to be difficult to finish the demoulding of finished product, even can make product distortion or damaged when the demoulding.
Simultaneously, existing hot forming tool structure function is simple, its action need be controlled by the driving arrangement of peripheral hardware, as cam, cylinder, hydraulic mechanism etc., these driving arrangements take big quantity space, when the cylinder stroke is long, can make the huge occupation of land of make-up machine build many even can raise the level height of operating desk, be not easy to manually-operated.And the space in the mould is not fully utilized, and the waste that driving arrangement has also brought material additionally is set.
Summary of the invention
Technical problem to be solved by this invention is, a kind of hot forming tool of using is provided, can satisfy the demoulding of complex-shaped plastic containers, comprise upper die body and lower mold body, described upper die body and lower mold body comprise the die cavity unit of a plurality of container formations, described lower mold body is provided with first top board and second top board, corresponding each the die cavity unit of described first top board is provided with many thimbles, corresponding each the die cavity unit of described second top board is provided with push rod, and described first top board offers the through hole that passes for described push rod; Corresponding with described thimble, wall upper end, the chamber end face of die cavity offers through hole; Described push rod is arranged on the bottom of described die cavity unit, and the outer wall lower end of described die cavity chamber wall is to outer lug, and its cross section is stepped, is provided with die-cut clip in the end face edge of outer wall lower end bossing.
Further, the described second top board lower surface is provided with gag lever post, is used for regulating the initial position of described second top board, thus the distance of control push rod and cavity bottom.
When needing the moulding of recessed of oriented inside, the product bottom can described push rod be raised up at described cavity bottom by regulating gag lever post.
Described support bar adjustable ground is installed on the described frame, when described lower mold body is moved downwards, described second top board stops action after dropping to the height of described support bar under the effect of support bar, described lower mold body die cavity continues action downwards, described second top board is with respect to the upwards action of described lower mold body, and described support bar ejects the product in the described die cavity.
The through hole on wall top, described die cavity chamber is opened in wall top, chamber outwards protruding part, thereby makes the cross section of described thimble reach maximization, thereby reduces it to the pressure of product, avoids pressure to cross the bursting of senior general's product.
Described first top board does not have equipment such as peripheral hardware cylinder, and its action is controlled by the air chamber pressure in the lower mold body.
Be provided with air chamber in the described lower mold body, piston and piston rod are arranged in the air chamber, described first top board is connected with described piston rod, and described piston is divided into upper and lower two parts with air chamber.
Described lower mold body is provided with pore and following pore, and described upper and lower pore is connected with upper and lower air chamber in the die body respectively, the action of the pressure control piston bar of last lower chamber, thus control the action of described upper plate.
Described upper die body is provided with drawing plate, and described drawing plate is connected with stretching bar and stretching head.
Described upper die body is fixed on the frame, and described drawing plate is by driven by servomotor.
Described lower mold body is by hydraulic-driven.
Owing to adopted hydraulic pressure or air cylinder driven, its accuracy height compared with traditional cam drive, does not have the wearing and tearing of cam, and clip need not the binder ring in conjunction with closely, thereby can the more complicated product of production moulding.
Be provided with gag lever post between described second top board and described first top board, limit the stroke that described first top board is advanced.
The present invention program's workflow is: sheet material is sent thermoforming machine to, lower mold body is upwards moved up to last, the lower mold body clip contacts, then stretch bar and stretching head moves downwards, sheet material is stretched and forms air cavity at sheet material and upper die body, make sheet material be close to the die cavity machine-shaping of lower mold body toward described air cavity pressurization, upwards action of stretching head after the moulding, and then lower mold body and upper die body quick pressing are finished punching, lower mold body is moved downwards after the punching, first top board upwards pushes up under the air chamber pressure effect simultaneously, utilize thimble that edge and the lower mold body die cavity that product has back-off broken away from by force, first top board is finished after the demoulding for the first time, described lower mold body continues to descend, described second top board stops action after dropping to the height of described support bar under the effect of support bar, described lower mold body die cavity continues action downwards, described second top board is with respect to the upwards action of described lower mold body, thereby described support bar ejects the product in the described die cavity, last described lower mold body, first top board, second top board resets and prepares to enter next workflow.
Implement the present invention, have following beneficial effect:
The present invention utilizes thimble to the demoulding by force of product back-off place, mode by the secondary demoulding to complex-shaped, carry out the demoulding with the strong product of die body adhesion, stay the upper surface of pit or bursting product outer wall flange when avoiding the demoulding in the product bottom, improve this type of product percent of pass, hot forming tool can be applied on the more complicated goods of shape in plastic processing, widen its application; Increase the thickness of clip, strengthened the intensity of clip, prolonged die life; Adopt hydraulic pressure and air cylinder driven, the accuracy height, therefore camless wearing and tearing need not the binder ring; To drive cylinder and be integrated on the die body, and reduce rack space and take up an area of the space, complete machine structure is simplified in the use of saving material.
