Abstract
The utility model discloses a hot pressing die used for producing a ceiling of a big truck. The hot pressing die comprises an upper die 1, a lower die 2 and a product ejection mechanism, wherein the upper die 1 and the lower die 2 are respectively provided with a heating device, the junction surface of the upper die 1 and the lower die 2 forms a cavity used for moulding a ceiling product 3, the lower die 2 is provided with a sunken flash cavity 2.1, and the lower surface of the upper die 1 is provided with a shearing block 1.1 which is arranged in the flash cavity 2.1 in a press fit manner. The hot pressing die disclosed by the utility model is characterized in that vertical length a of the shearing side of the shearing block 1.1 is 25-30mm, and the depth b of the flash cavity 2.1 is 35-40mm. The hot pressing die disclosed by the utility model can be used for preventing an excessive panel body material to be processed from falling into the flash cavity during die assembly, a moulded ceiling product can meet the requirement, and the hot pressing die disclosed by the utility model belongs to the die technical field.
Description
Technical field
The utility model belongs to technical field of mold, especially relates to a kind of hot-die for the production of the truck ceiling.
Background technology
Hot-die comprises upper die and lower die and product ejecting mechanism, and upper die and lower die are equipped with heater, and the faying face of upper die and lower die forms the shape chamber that shaped article is used.The operation principle of hot-die is: after the upper die and lower die heating, material plate body to be processed is laid on the counterdie, patrix is depressed matched moulds moulding, cooling and demolding, ejecting product.The counterdie of existing hot-die for the production of the truck ceiling is provided with a recessed material overflow cavity, the patrix lower surface is provided with a cutout that can be force-fitted in the material overflow cavity, cutout be positioned at the counterdie material overflow cavity directly over, in the matched moulds process, the cutout of patrix is pressed in the material overflow cavity.
During matched moulds, the cutout part had slipped in the material overflow cavity before patrix contacted with material plate body to be processed, and during upper and lower mould matched moulds, material plate body to be processed melts, moulding.
The cutout sheared edge vertical extension of existing hot-die is generally 10mm-15mm, the material overflow cavity degree of depth is 20mm-25mm, after in cutout slips into material overflow cavity, when material plate body to be processed melts, because cutout sheared edge vertical extension is inadequate, the sheared edge of cutout does not also form sealing with the material overflow cavity wall, causes the material of molten condition to fall in the material overflow cavity, want light when finally causing the product of moulding to compare design, intensity etc. are undesirable.
The utility model content
Technical problem to be solved in the utility model is: a kind of hot-die for the production of the truck ceiling is provided, can prevent during matched moulds material plate body to be processed too much fall into material overflow cavity, guarantee that the product of moulding meets the requirements.
Technical solution adopted in the utility model is: a kind of hot-die for the production of the truck ceiling, it comprises upper die and lower die and product ejecting mechanism, upper die and lower die are equipped with heater, the faying face of upper die and lower die forms the shape chamber that shaped article is used, counterdie is provided with a recessed material overflow cavity, the patrix lower surface is provided with a cutout that can be force-fitted in the material overflow cavity, and described cutout sheared edge vertical extension is 25mm-30mm, and the described material overflow cavity degree of depth is 35mm-40mm.
Described cutout sheared edge vertical extension is 25mm, and the described material overflow cavity degree of depth is 35mm.
The beneficial effects of the utility model are: the utility model is for the production of the hot-die of truck ceiling, on the basis of original hot-die, prolong the length of cutout sheared edge and then improved cutout sheared edge vertical extension, the degree of depth of also having deepened material overflow cavity simultaneously.During matched moulds, before material plate body to be processed melts, the sheared edge of cutout forms closed state with the material overflow cavity inwall, after waiting for that the rapidoprint plate body melts, material can not fall into material overflow cavity easily, only have unnecessary material just can be sheared piece and be extruded in the material overflow cavity, guaranteed the needed material amount of finished product, guarantee the intensity that product is required.
Description of drawings
Fig. 1 is the utility model overall schematic.
Fig. 2 is A place enlarged drawing among Fig. 1.
Among the figure, 1, patrix, 1.1, cutout, 2, counterdie, 2.1, material overflow cavity, 3, product, a, vertical extension, b, the degree of depth.
The specific embodiment
Below be the utility model preferred embodiment, but therefore do not limit protection domain of the present utility model.
Shown in seeing figures.1.and.2, a kind of hot-die for the production of the truck ceiling of the utility model, it comprises patrix 1, counterdie 2 and product ejecting mechanism, patrix 1 and counterdie 2 are equipped with heater, the faying face of patrix 1 and counterdie 2 forms the shape chamber of shaped article 3 usefulness, counterdie 2 is provided with a recessed material overflow cavity 2.1, patrix 1 lower surface is provided with a cutout 1.1 that can be force-fitted in the material overflow cavity 2.1, the utility model and existing hot-die structure are basically identical, unique different place is that the cutout 1.1 sheared edge vertical extension a on the utility model are 25mm-30mm, and described material overflow cavity 2.1 degree of depth b are 35mm-40mm.
As preferably, described cutout 1.1 sheared edge vertical extension a are 25mm, and described material overflow cavity 2.1 degree of depth b are 35mm.The utility model, has prolonged the length of cutout 1.1 sheared edges and then has improved cutout 1.1 sheared edge vertical extension, the degree of depth of also having deepened material overflow cavity 2.1 simultaneously on the basis of original hot-die for the production of the hot-die of truck ceiling.During matched moulds, before material plate body to be processed melts, the sheared edge of cutout 1.1 forms closed state with material overflow cavity 2.1 inwalls, the closed state of herein saying refers to still to have between the sheared edge of cutout 1.1 and material overflow cavity 2.1 inwalls fixed gap in fact, just the width in this space can't flow down from this slit after the material plate body thawing to be processed voluntarily; After that is to say that wait rapidoprint plate body melts, material can not fall into material overflow cavity 2.1 easily, only has unnecessary material just can be sheared piece 1.1 and is extruded in the material overflow cavity 2.1, has guaranteed the needed material amount of finished product, guarantees the intensity that product is required.
Operation principle of the present utility model is consistent with existing hot-die, no longer gives unnecessary details here.
