Abstract
The utility model discloses an integration mould for rotational moulding product shaping and setting, including last mould and lower mould, it is formed with the mould die cavity to go up mould and lower mould closed back inside, be equipped with a plurality of mounting holes on going up the mould, install the design bolt in the mounting hole, the end of design bolt stretches into the mould die cavity, hoist out the lower mould with last mould and design nut together after the product shaping, the product progressively stabilizes to when keeping the outline shape and not subsiding under cooling fan's cooling, can demolish all the design nuts on the mould, the product will break away from with last mould thereupon, top domes after having prevented the product from demolding receive high temperature soft deformation or subside, the integrality and the quality of the outward appearance of product have been guaranteed, and the cost of making the design frock alone has been reduced.
Description
Technical Field
The utility model relates to a mould, especially an integration mould that is used for rotational moulding product shaping and stereotyping.
Background
The prior production process comprises two steps of molding a product by a rotational molding die, removing the die and then putting a shaping tool into the product to fix the appearance of the product. The concrete embodiment is as follows: polyethylene raw materials are poured into a mold in a powdery state, the mold enters a hearth along a frame arm together to be rolled and heated for 360 degrees (220-350 ℃) after being closed, the raw materials are bonded and molded along the inner mold wall of the mold along with the passage of time, and the mold is required to be disassembled considering that products cannot be cooled to normal temperature based on production efficiency and fuel gas saving, so the products still have high temperature (about 60-80 ℃) after being opened, the surfaces of the products are still not completely cured and are in a soft state, the top arches of the products directly collapse or deform due to gravity, the products are directly scrapped, the product molding and shaping in the existing rotational molding production process are separated, the problem that the product structure collapses or deforms cannot be solved by the process of molding first and shaping, different tools are required to be manufactured respectively for the product molding and shaping, and the cost is increased.
Disclosure of Invention
In order to overcome the defects of the prior art, the utility model provides an integrated mould for rotational moulding product forming and setting.
The utility model provides a technical scheme that its technical problem adopted is:
the utility model provides an integration mould for rotational moulding product shaping and setting, includes mould and lower mould, it is formed with the mould die cavity to go up mould and the inside back of lower mould closure, be equipped with a plurality of mounting holes on going up the mould, install the design bolt in the mounting hole, the end of design bolt stretches into in the mould die cavity.
The inner side of the mounting hole is provided with threads and is in threaded connection with the shaping bolt.
The shaping bolts are symmetrically arranged on the upper die.
The length of the tail end of the shaping bolt extending into the die cavity is more than 20 mm.
The utility model has the advantages that: the utility model discloses install the setting nut additional on last mould, it is fixed through threaded connection between setting nut and the last mould, hoist out the lower mould with last mould and setting nut together after the product shaping, the product is gradually stabilized to when keeping the outline shape and not subsiding under cooling fan's cooling, can demolish all setting nuts on the mould, the product will break away from with last mould thereupon, top domes after having prevented that the product from demolding receive high temperature soft deformation or subside, the integrality and the quality of the outward appearance of product have been guaranteed, and the cost of making the setting frock alone has been reduced.
Drawings
The present invention will be further explained with reference to the drawings and examples.
Fig. 1 is a schematic structural diagram of the present invention;
fig. 2 is a schematic cross-sectional view of the present invention.
Detailed Description
Referring to fig. 1, an integrated mold for molding and shaping rotational molding products comprises an upper mold 1 and a lower mold 2, a mold cavity 3 is formed inside the upper mold 1 and the lower mold 2 after the upper mold 1 and the lower mold are closed, a plurality of mounting holes 4 are formed in the upper mold 1, shaping bolts 5 are mounted in the mounting holes 4, the tail ends of the shaping bolts 5 extend into the mold cavity 3, threads are arranged on the inner sides of the mounting holes 4 and are in threaded connection with the shaping bolts 5, after raw materials are poured into a mold for mold assembly, the shaping nuts, the upper mold and the lower mold enter a rotational molding furnace chamber together for heating and baking, as the mold is heated in the rotation and revolution directions in the furnace chamber, the raw materials are gradually changed into molten gel from powder after being heated along with the lapse of time, the raw materials are naturally bonded along the inner mold wall layer of the mold, including bonding on the coarse threads of the shaping nuts, so that the products and the shaping nuts are integrated, after the product is formed, the mold leaves a hearth along with a frame arm and a travelling crane, an upper mold, a shaping nut and a product are lifted out of the mold along with the travelling crane during mold opening, a cooling area outside the hearth is cooled by a fan, the shaping nut can be taken out after the product is cooled for a certain time, and the product is separated from the upper mold.
The shaping bolts 5 are symmetrically arranged on the upper die 1, in the embodiment, the shaping bolts 5 are symmetrically arranged along the XY axial direction, so that the stress of a product after die opening is ensured to be symmetrical and even, and the product is ensured not to deform.
The length of the tail end of the shaping bolt 5 extending into the die cavity 3 is more than 20mm, the extending length is larger than the thickness of a product, the adhesion of materials on the coarse thread of the shaping nut is ensured, and the product and the shaping nut are integrated.
The above embodiments do not limit the scope of the present invention, and those skilled in the art can make equivalent modifications and variations without departing from the overall concept of the present invention.
