Description
Technical field
The utility model is related to injection mold, more particularly to a kind of grid double-face plastic tray injection mold and its leg into
Type mechanism.
Background technology
In the logistics progress such as storage and transport, pallet is widely used, the enabling capabilities of pallet are strong and weak greatly to be taken
Certainly in the enabling capabilities of footing, in the injection mold for producing traditional tray main body, it usually needs set on dynamic model either cover half
Putting many is used for the shaping column in shaping groove hole, when being separated with dynamic model and cover half, shaping column and the plastic pallet of shaping
It is separated from each other, causes and groove hole characteristic is molded on plastic pallet, that is, the plastic pallet structure such as notification number produced is
A kind of matrix pattern footing of CN202337416U plastic pallet of Chinese utility model, it includes tray main body, the tray main body
In open support feet and prong be formed with grid hole, tray main body, each angle of tray main body lower end is all formed with single support feet,
Such support feet internal structure, which can be found in run through in accompanying drawing 1 and accompanying drawing 2 in above-mentioned existing patent, support feet, is provided with some grooves
Hole.
It is due to support where footing although cost of material used in the tray main body of the above-mentioned type is greatly lowered
The enabling capabilities of point are most strong on whole pallet, and therefore, when actually carrying the object of part heavier-weight, object is inevitable
Need to contact with pallet, and user would generally be placed in contact point footing position, due to the footing of above-mentioned tray main body
There is simple recess hole in place, its effective contact area between object is smaller, the abrasion that tray main body is produced than more serious,
Actual life is relatively low.
Utility model content
In view of the deficienciess of the prior art, first purpose of the present utility model is to provide a kind of leg forming machine
Structure, the pallet foot service life that it is produced is longer.
