Abstract

The utility model relates to a once-forming die for paper tableware box, comprising a lower die seat and an upper die which is arranged above the lower die seat and is driven by a power mechanism of the lower die. The lower die of the box bottom and the lower die of the box cover are arranged in the same lower die seat; and the upper die above the lower die seat consists of an upper die of the box bottom and an upper die of the box cover. The technical proposal of the utility model allows the die of the box bottom and the box cover to be arranged in the same die, with one-time molding in process; hereby, the production efficiency is greatly increased, the labor intensity is reduced, the production cost is decreased and the pass rate of the product is increased.

Description

The paper lunch-box one-time-shaped mould

Technical field

The utility model is a kind of paper lunch-box one-time-shaped mould.

Background technology

At present during processing disposable paper cutlery box, generally be its box bottom to be divided and the lid part is processed respectively, general so just need two molds, operation is comparatively bothered, its yield rate is lower, also make the investment of enterprise bigger, and its operating cost is also higher.

Summary of the invention

The purpose of this utility model is: thus a kind of paper lunch-box one-time-shaped mould that can make the paper lunch-box one-shot forming can enhance productivity, reduce production costs, improve yield rate of design.

The utility model comprises installs the patrix that its die shoe and side mounted thereto are driven by its actuating unit, and mould and lid counterdie are positioned on the same die shoe under the box, the patrix of its top by corresponding with it box at the bottom of patrix and lid patrix form.

The technical solution of the utility model be with at the bottom of the box and the mould of lid be installed on the same mould, make it add the one-shot forming in man-hour, can enhance productivity greatly like this, reduce labor intensity, reduce production costs, and can improve the yield rate of product.

The installation of patrix can be adopted following form at the bottom of lid patrix and the box: there are last gusset piece and top board in the die shoe top, patrix is connected with the guide shaft and the column that are installed in separately between gusset piece and the top board respectively at the bottom of lid patrix and the box, and is positioned at the below of top board.

Be to guarantee product quality, have on the lower surface of the top board of patrix at the bottom of the mounting box and lid patrix between patrix at the bottom of the box and the lid patrix backstay or on locating piece.Last backstay or go up locating piece and can at first the paper embryo be pushed down and make its location when equipment work if go up locating piece structure for fixedly the time, can pass through the stroke complete operation of adjusting mould during equipment work.In addition, last backstay or go up locating piece and also can be designed as movable form, as: have with last backstay on the top board or go up the corresponding hole of locating piece, last backstay (piece) passes this hole and is connected with the upperpush rod with the spring cooperation above the top board.Like this, during equipment work, last backstay (piece) is at first pushed down the paper embryo, along with the motion of patrix, under the effect of die shoe or corresponding component, in the hole on last backstay (piece) the retraction top board, thereby guarantees that the paper embryo is injury-free.

In addition, the following locating piece that adapts with the counterdie longitudinal length also can be set on the upper surface of the die shoe between mould under the box and the lid counterdie.Equally, following locating piece both can be fixed form, also can be activity form.As: there are backing board and bottom plate in the die shoe below, and following locating piece hole is arranged on die shoe and the backing board, and following locating piece is loaded in this hole; There is a little push rod upper end that cooperates with spring to be arranged in the locating piece hole.For guaranteeing the direction of motion of little push rod, the lower end of little push rod preferably passes bottom plate, and its middle part then can be provided with the evagination ring, and spring is loaded between evagination ring and the bottom plate.

When locating piece existed simultaneously up and down, they preferably were in relative position.
