Description

Adjustable bottom die

Technical Field

The utility model relates to a shoes production facility field, in particular to adjustable die block.

Background

Common rubber shoes and plastic shoes on the market are usually produced by injection molding through an adjustable bottom mold, wherein the adjustable bottom mold comprises a bottom mold and a shoe tree, and an injection molding cavity is formed between the bottom mold and the shoe tree. The existing adjustable bottom die is generally provided with an injection molding through hole, and plastic is injected into an injection molding cavity, so that a shoe body and a shoe sole are combined into a whole. This kind of mode of moulding plastics needs the manual work to cut off the stub bar, if the export of the through-hole of moulding plastics is seted up in the bottom surface of die block, and the stub bar can destroy the whole anti-skidding structure of sole, causes anti-skidding effect to descend, if the export of the through-hole of moulding plastics is seted up in the side of die block, then can destroy the wholeness of shoes design.

Chinese patent publication No. CN108995122A discloses a novel disposable upper connecting molding injection structure for shoes and a novel injection molding method, the injection structure includes die carrier, shoe mold, last and material injection mechanism, the utility model discloses an injection molding method, including following steps: s1, fixing the shoe upper; s2, fixing the shoe tree; s3, forming the upper; s4, lifting a last; and S5, repeating the steps from S1 to S4, and circularly producing. The utility model discloses a set up the feed port in the inside of last, the feed port extends to the bottom of last always, and runs through the bottom surface of last, and like this when injecting, the sole material can be followed the bottom of last and outwards jetted to the injection stub bar can not be reserved to the sole outsole portion of formation. The last and the material injection molding mechanism need to be aligned, the material injection molding mechanism can inject materials into the last, the position of the last is inconvenient to adjust, tolerance easily exists in the production, manufacturing and installation processes of the machine table, and if the last and the shoe mold cannot be aligned, the vamp sleeved on the last is damaged by clamping, the shoe mold cannot be normally closed, and the injection molding quality of the shoe is affected. Therefore, it is urgently required to provide an adjustable bottom die.

SUMMERY OF THE UTILITY MODEL

Therefore, to foretell problem, the utility model provides a simple structure, low in production cost, convenient adjustment, the efficient adjustable die block of adjustment.

In order to achieve the technical problem, the utility model adopts the solution that the adjustable bottom die comprises a left die and a right die which can be separated and reunion, the left die and the right die are respectively provided with a connecting plate, the left die and the right die are respectively movably arranged on the connecting plate, and a releasable locking device is respectively arranged between the left die and the bottom plate and between the left die and the right die and the bottom plate.

The further improvement is that: the locking device. Including first positioning screw, second positioning screw, third positioning screw, the tip seted up screw hole confession first positioning screw goes into before the connecting plate, the preceding tip of left side mould or right mould can contradict in first positioning screw, seted up respectively on the side of left side mould or right mould and the connecting plate screw hole and the waist hole that second positioning screw passed, set up screw hole confession on the connecting plate third positioning screw penetrates, the side of left side mould or right mould can contradict in third positioning screw.

By adopting the technical scheme, the beneficial effects of the utility model are that: 1. the bottom die is convenient to adjust, and the bottom die can be adjusted by rotating the first positioning screw rod, the second positioning screw rod and the third positioning screw rod; 2. the adjustment precision is high, and the required position can be conveniently adjusted through stepless adjustment of the threads; 3. the bottom die convenient to adjust can be matched with the position of the shoe tree better, and the injection molding quality of the shoe is further improved.

Fig. 1 is a schematic top view of an adjustable bottom die according to an embodiment of the present invention.

Fig. 2 is a schematic side view of the adjustable bottom mold and the shoe tree according to the embodiment of the present invention.

Detailed Description

The present invention will now be further described with reference to the accompanying drawings and specific embodiments.

Example (b):

referring to fig. 1 and 2 the embodiment of the utility model discloses what disclose is adjustable die block, the die block includes left mould 21 and the right mould 22 that can separate and reunion, the upper end has the groove 23 of moulding plastics behind left side mould 21 and the right mould 22 compound die, and shoe tree (not shown in the figure) can slide from top to bottom and set up in the groove 23 top of moulding plastics, and the lower tip of shoe tree can be embedded the groove 23 of moulding plastics, after the groove 23 is moulded plastics in the shoe tree embedding, still have the cavity of injection moulding sole in the groove 23 of moulding plastics.

In order to adjust the position between the bottom mold and the shoe tree conveniently, so that the shoe tree can be accurately embedded into the injection molding groove 23, the side edges of the left mold 21 and the right mold 22 are respectively provided with a connecting plate 3, the left mold 21 and the right mold 22 can be respectively movably arranged on the connecting plate 3, the front end part of the connecting plate 3 is provided with a threaded hole and is penetrated with a first positioning screw 33, the front end part of the left mold 21 or the right mold 22 can be abutted against the first positioning screw 33, the front and back position of the left mold 21 or the right mold 22 can be adjusted by adjusting the first positioning screw 33, the side surface of the left mold 21 or the right mold 22 is provided with a second positioning screw 31 through threads, the connecting plate 3 is provided with a waist hole for the second positioning screw 31 to penetrate, the connecting plate 3 is provided with a threaded hole and is penetrated with two third positioning screws 32, and the side surface of the left mold 21 or the right mold 22, third positioning screw 32 is located the place ahead and the rear of second positioning screw 31 respectively, and when first positioning screw 33 and third positioning screw 32 have been adjusted, after left mould 21 and the right mould 22 have been fixed a position promptly, locks second positioning screw 31, accomplishes the location of left mould 21 and right mould 22 promptly, can adjust in real time for the shoe tree can accurate embedding groove 23 of moulding plastics, makes the quality of the back shoes of moulding plastics further improve.
