Abstract
The invention relates to a step-by-step oblique ejection structure applied to the inside of a die, comprising an oblique ejector, an angle ejector rod, an oblique footstock, an elastic part and a guide block. Two ends of the angle ejector rod are respectively fixedly connected with the oblique ejector and the oblique footstock; and the oblique footstock is movably arranged on an ejector plate and can slide on the surface of the ejector plate. According to the oblique ejection structure disclosed by the invention, an action of ejecting out a product in a die with the oblique ejector is divided into two steps due to a bevel staggered dividing structure between the angle ejector rod and the guide block, firstly, the oblique ejector ejects out the product along a vertical direction, and secondly, the oblique ejector performs lateral core pulling. Since a product departing from a die does not have enclasping force for the oblique ejection structure any more, a product demoulded by adopting the oblique ejection structure is small in deformation and good in quality.
Description
Technical field
The present invention relates to a kind of pitched roof mechanism, particularly relate to a kind of substep pitched roof mechanism be applied in mould.
Background technology
In the production of injecting products, if there is more shallow side direction barb the inside of shaped article or outside, in order to the smooth demoulding, usually need to arrange a kind of pitched roof mechanism in mould.Pitched roof mechanism has more obvious economic advantages when processing and having the product of more shallow side direction barb than side core-pulling, and its existing shaping effect, also ejects effect, is the parts of a kind of special shape in mould.
Fig. 1 is common pitched roof mechanism operation principle schematic diagram.Pitched roof mechanism comprises oblique top 1, angle ejector rod 2, guide pad 5 and tilted footstock 4, the two ends of angle ejector rod 2 respectively with oblique top 1 and tilted footstock 3 hinged, be provided with through hole in guide pad 5, angle ejector rod 2 is through the through hole in guide pad 5; It is inner that oblique top 1 is positioned at mould 7, and oblique top 1 and mould one are used from shaped article, and tilted footstock 3 is movably arranged on top board 6; During the demoulding, top board 6 moves upward, push rod 8 and oblique top 1 ejecting product 9 gradually, and oblique top 1 is tilted to the left gradually in the process, abdicates the barb of product 9 to take out product 9.
In the process of the pitched roof mechanism ejecting product 9 of above-mentioned prior art, oblique top 1 is separated with product 9 gradually along the route that is tilted.In the initial stage of the demoulding, the fork pin 91 with barb of product 9 is still positioned at mould, and product 9 pairs of oblique tops 1 have enclasping force, and fork pin 91 can bend along with the motion of oblique top 1, and demoulding product 9 out is easily out of shape.
Summary of the invention
The technical problem to be solved in the present invention is: the problem easily making demoulding deformation of products out in order to solve existing pitched roof mechanism, and the pitched roof mechanism that the invention provides a kind of multiple step format solves the problems referred to above.
The technical solution adopted for the present invention to solve the technical problems is: a kind of substep ramp-roof structure, comprises oblique top, angle ejector rod, tilted footstock, elastomeric element and guide pad; The two ends of angle ejector rod are fixedly connected with tilted footstock with oblique top respectively; Tilted footstock is movably arranged on top board, and tilted footstock can slide at top board surface; Angle ejector rod is positioned at the inside of mould, and a side of angle ejector rod is provided with the first inclined-plane; The surface of guide pad is provided with second inclined-plane corresponding with the first inclined-plane of angle ejector rod, for changing the motion path of angle ejector rod on the motion path that guide pad is positioned at angle ejector rod; Described elastomeric element comprises two guide rails, two springs and a slide block, two guide rail parallels are fixedly mounted on mould inside, angle ejector rod is between two guide rails, slide block is arranged between two guide rails, slide block is embedded with many balls, ball is between slide block and angle ejector rod, and two springs are arranged on guide rail interior respectively, and two springs in elastomeric element promote slide block applies to be pointed to by angle ejector rod guide pad direction power to angle ejector rod.
Product in multiple step format ramp-roof structure ejection die is divided into two steps: the first step is vertically ejecting product, and second step is side core-pulling.
The invention has the beneficial effects as follows: (1) multiple step format of the present invention ramp-roof structure carries out side core-pulling again after by complete for the product in mould ejection die, the product leaving mould no longer has enclasping force to pitched roof mechanism, and therefore demoulding product is out not easy distortion.
(2) traditional pitched roof mechanism utilizes guide pad to limit the motion path of angle ejector rod, this needs to have higher dimensional fits between angle ejector rod and the size of guide pad, after this dimensional fits has been broken in the wearing and tearing of angle ejector rod, angle ejector rod is stressed in guide pad to have become unstable and has easily fractureed; Pitched roof mechanism of the present invention utilizes the inclined-plane of guide pad to change the motion path of angle ejector rod, dimensional fits between angle ejector rod and guide pad requires very low, the impact that the wearing and tearing of angle ejector rod normally work on pitched roof mechanism of the present invention is very little, improves the working life of pitched roof mechanism.

Detailed description of the invention
In conjunction with the accompanying drawings, the present invention is further detailed explanation.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present invention are described in a schematic way, and therefore it only shows the formation relevant with the present invention.
(embodiment 1)
As shown in Figures 2 to 4, the present embodiment ramp-roof structure comprises oblique top 1, angle ejector rod 2, tilted footstock 3, elastomeric element 4 and guide pad 5; The two ends of angle ejector rod 2 are fixedly connected with tilted footstock 3 with oblique top 1 respectively; Tilted footstock 3 is movably arranged on top board 6, and tilted footstock 6 can at top board 6 surface sliding; Angle ejector rod 2 is positioned at the inside of mould 7, and a side of angle ejector rod 2 is provided with the first inclined-plane 21; The surface of guide pad 5 is provided with second inclined-plane 51 corresponding with the first inclined-plane 21 of angle ejector rod 2, for changing the motion path of angle ejector rod 2 on the motion path that guide pad 5 is positioned at angle ejector rod 2.
Elastomeric element 4 comprises two guide rails, 41, two springs 42 and a slide block 43, two guide rails 41 are parallel, and to be fixedly mounted on mould 7 inner, angle ejector rod 2 is between two guide rails 41, slide block 43 is arranged between two guide rails 41, slide block 43 is embedded with many balls 44, ball 44 is between slide block 43 and angle ejector rod 2; Two springs 42 are arranged on guide rail 41 inside respectively, and elastomeric element 4 applies by slide block 3 pairs of angle ejector rods 2 power being pointed to guide pad 5 direction by angle ejector rod 2.
During die sinking, guide pillar 10 drives top board 6 to move upward, and push rod 8 and oblique top 1 move upward ejecting product 9 jointly.After product 9 completely break away from moulds 7, angle ejector rod 2 continues the first inclined-plane 21 in the process moved upward and touches the second inclined-plane of guide pad 5, angle ejector rod 2 drive oblique top 1 left upper direction complete side core-pulling action.Because side core-pulling action is carried out after product 9 leaves mould 7 completely, product 9 no longer has enclasping force to oblique top 1, and therefore demoulding product 9 deformation is out little, and quality is good.
With above-mentioned according to desirable embodiment of the present invention for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this invention technological thought, can carry out various change and amendment completely.The technical scope of this invention is not limited to the content on description, must determine its technical scope according to right.
