In technique scheme, described in renovate shovel and be shaped with hole in briquetting, in described hole, being provided with by pin can be along the roller of described pin rotation.
In technique scheme, described roller is made up of toughness material.
In technique scheme, on described installing plate, be also provided with described in regulating and renovate the knurly screw that shovels briquetting position.
In technique scheme, on described slide plate 7, be shaped with the U-shaped groove that size coordinates with described oil cylinder.
In technique scheme, described U-shaped groove is embedded with the oil cylinder protector of U-shaped.
Described slide bar is even number root, is evenly distributed on the both sides of described piston rod.
The present invention has adopted roller press-down type automatic cover-turning device, renovate in process, renovate shovel briquetting moving line in full accord with gathering sill, therefore to finally having a downward movement locus, it presses down effect far above prior art, can guarantee all back-off tegillums all to cover, by manual operation, therefore improve production efficiency without again.
Below in conjunction with accompanying drawing, embodiments of the present invention are described further.

Detailed description of the invention
As Figure 1-3, a kind of roller press-down type automatic cover-turning device of injection mold, comprises mould bases 1, on mould bases 1, automatic cover-turning mechanism is installed.
Automatic cover-turning mechanism comprises that guide plate 2, the two relative sides of guide plate 2 that are arranged on mould bases 1 both sides are provided with gathering sill 21 and guide runner 22.In two guide runners 22, be provided with lifting slider 3, be shaped with two through holes in lifting slider 3, be provided with a guide pillar 31 in each through hole, lifting slider 3 can slide up and down along guide pillar 31, and wherein guide pillar 31 is fixed on mould bases 1.
As shown in Figure 5, renovate shovel briquetting 8 for being similar to " L " font structure, the lateral part in " L " font structure is the rectangular leg-of-mutton tri-prismoid in bottom surface.In tri-prismoid, be shaped with hole, be provided with pin in hole, on pin, being provided with can be along the roller 81 of pin rotation.Wherein roller 81 is made up of the good material of toughness, and the present embodiment selects rubber to make.
On installing plate 6, be also shaped with 2 through holes, be evenly distributed on the both sides of piston rod, in the course of work, play good balanced action.Each through hole is penetrated with a slide bar 4, and one end of slide bar 4 is fixed on installing plate 6, and the other end is fixed on slide plate 7.Bearing 10 is installed in slide plate 7 both sides, and bearing 10 matches with gathering sill 21, and can slide along gathering sill 21.Gathering sill 21 is made up of straight trough 211 and arc crank slot 212 two parts, as shown in Figure 4.
As the improvement to the present embodiment, on installing plate 6, be also provided with the knurly screw 61 of renovating shovel briquetting 8 positions for regulating, knurly screw 61 is similar to bolt, and its threaded part is screwed in to regulate and renovates on shovel briquetting 8.Because mould manufacture can produce certain error, therefore renovate shovel briquetting 8 be arranged on installing plate 6 after in certain error range its height may be different.To this, knurly screw 61 just can be adjusted to sustained height.In addition, when this mechanism is applied on different moulds, the back-off tegillum height that knurly screw 61 is manufactured for corresponding mould, will renovate shovel briquetting 8 positions and carry out integrally-regulated.
As the optimization to the present embodiment, on slide plate 7, be shaped with the U-shaped groove that size coordinates with oil cylinder 5.When piston rod extends, oil cylinder 5 enters U-shaped groove, can reduce like this size of mould, saves the material of mfg. moulding die, and reduces floor space.
Above-mentioned U-shaped groove is embedded with the oil cylinder protector 71 of U-shaped.The length of the oil cylinder protector 71 of U-shaped is greater than the length (slide plate 7 width) of U-shaped groove; be generally 2-6 doubly; in piston rod telescopic process, ensure that oil cylinder does not depart from oil cylinder protector 71, thereby prevented that oil cylinder 5 and slide plate 7 from bumping, and plays the effect of protection oil cylinder 5.
The course of work of the present invention is as follows:
After injection mold die sinking, as shown in Figure 1, the piston rod of oil cylinder 5 extends, and drives installing plate 6 to move to mold center, and installing plate 6 drives slide plate 7 to move together by slide bar 4, and the bearing 10 on slide plate 7 also slides together along gathering sill 21.In the time that bearing 10 slides into the straight trough 211 of gathering sill 21 and the junction of arc crank slot 212, renovate shovel briquetting 8 front ends and just move to the below of back-off tegillum.When bearing 10 continues slip meeting and makes slide plate 7 keep former direction to move along the track of arc crank slot 212, also have the speed moving up, slide plate 7 drives lifting slider 3 to move up together with installing plate 6 by slide bar 4, makes lifting slider 3, installing plate 6 and slide plate 7 remain on sustained height.When bearing 10 slides into after the peak of arc crank slot 212, lifting slider 3, installing plate 6 and slide plate 7 will synchronously glide under the effect of bearing 10 and arc crank slot 212, renovate shovel briquetting 8 simultaneously and also drive back-off tegillum to press down until buckle completely.
Find out thus, the present embodiment is renovated in process, renovate shovel briquetting moving line in full accord with gathering sill, therefore to finally having a downward movement locus, it presses down effect far above prior art, can guarantee all back-off tegillums all to cover, by manual operation, therefore improve production efficiency without again.
And as the one of the present embodiment is improved, renovate that on shovel briquetting 8, installed can be along the roller 81 of pin rotation, and roller 81 is made up of the good material of toughness.Make to renovate the rolling friction that shovel briquetting and the sliding friction of back-off tegillum replace with roller 81 and back-off tegillum in the time renovating, add the property of toughness of roller 81 materials itself, back-off tegillum is played a very good protection.
More than describe preferred embodiment of the present invention in detail.The ordinary skill that should be appreciated that this area just can design according to the present invention be made many modifications and variations without creative work.Therefore, all technical staff in the art on the basis of existing technology by the available technical scheme of logical analysis, reasoning, or a limited experiment, all should fall within the scope of protection of the present invention under this invention's idea.
