Abstract
The utility model discloses a kind of automobile injection mold secondary core-pulling mechanism, the big shovel base including being fixed on moving template bottom surface, big sliding block, small slide block, fixed block and built-in spring between big shovel base, solid plate, front cavity and rear cavity, the inclined guide pillar across big shovel base and big sliding block, cooperation are in big sliding block and outwardly extending contour screw and the external spring on contour screw for the big sliding block that rebounds are arranged in.The mutual cooperation that the utility model passes through the components such as shovel base, big sliding block, small slide block, fixed block, built-in spring and external spring greatly, enable the completion core pulling twice of injection mold continuity, so that shaped article is detached from back-off, smoothly complete demoulding, demoulding efficiency is not only increased, and the quality demoulded is also improved.
Description
Technical field
The utility model relates to mold mechanism technical fields, and in particular to a kind of automobile injection mould slide block secondary core-pulling
Structure.
Background technique
With the continuous development of auto industry, plastics injection mould is one of indispensable tool of automobile manufacture, existing
Have in technology, when a shaped article because side wall cannot demould, on mold with the back-off of the directions differences such as hole, groove, boss
Design needs multiple core pulling directions, since the operation in multiple core pulling directions needs to expend the more time, so that entire demoulding effect
Rate is lower, and quality of mold release is also unable to get guarantee.
Summary of the invention
Goal of the invention: it in order to overcome the deficiencies in the prior art, provides a kind of quick, high by twice core pulling realization
Imitate the automobile injection mould slide block secondary core-pulling mechanism of demoulding.
Technical solution: to achieve the above object, the utility model provides a kind of automobile injection mold secondary core-pulling mechanism, packet
Include the big shovel base being fixed on moving template bottom surface, the big sliding block between big shovel base, solid plate, front cavity and rear cavity, small
Sliding block, fixed block and built-in spring, the inclined guide pillar across big shovel base and big sliding block, cooperation are in big sliding block and outwardly extending
Contour screw and the external spring that the big sliding block that is used to rebound on contour screw is set.
Further, the scuppit base matched with small slide block for pushing small slide block is provided on the big shovel base.
Further, the scuppit base is fixed by screws on big shovel base.
Further, it is provided with to match with contour screw on the solid plate and be carried out for the going-back position to big sliding block
The limited block of limit.
Further, it is provided with block on the contour screw, the external spring is between block and limited block.
Further, it is provided with wear-resistant block on the contact surface of the solid plate and big sliding block, because during core pulling, greatly
Sliding block needs slidably reciprocate on solid plate, and the setting of wear-resistant block is able to ascend the wearability of cover half plate surface, prevents solid plate
It is worn with big sliding block.
The utility model has the advantages that the utility model is compared with prior art, by shoveling base, big sliding block, small slide block, fixed block, interior greatly
The mutual cooperation for setting the components such as spring and external spring, enables the completion core pulling twice of injection mold continuity, so that at
Type product is detached from back-off, smoothly completes demoulding, not only increases demoulding efficiency, and the quality demoulded is also improved.
Detailed description of the invention
Fig. 1 is the overall structure overall situation schematic diagram of the utility model；
Fig. 2 is structural schematic diagram of the utility model in automobile injection mold.
Specific embodiment
In the following with reference to the drawings and specific embodiments, the utility model is furtherd elucidate, it should be understood that these embodiments are only used for
Illustrate the utility model rather than limitation the scope of the utility model, after having read the utility model, art technology
Personnel fall within the application range as defined in the appended claims to the modification of the various equivalent forms of the utility model.
As depicted in figs. 1 and 2, the utility model provides a kind of automobile injection mold secondary core-pulling mechanism, including is fixed on
It is big shovel base 3 on 2 bottom surface of moving template, the big sliding block 6 between big shovel base 3, solid plate 1, front cavity 12 and rear cavity 11, small
Sliding block 7, fixed block 5 and built-in spring 71, across the inclined guide pillar 4 of big shovel base 3 and big sliding block 6, cooperation in big sliding block 6 and to
The contour screw 9 of outer extension and the external spring 15 that the big sliding block 6 that is used to rebound on contour screw 9 is arranged in, big shovel on base 3 set
It is equipped with the scuppit base 31 matched with small slide block 7 for pushing small slide block 7, scuppit base 31 is fixed on big shovel base 3 by screw 32
On, it is provided on solid plate 1 and matches the limited block 13 limited for the going-back position to big sliding block 6 with contour screw 9,
Block 14 is provided on contour screw 9, external spring 15 between block 14 and limited block 13, solid plate 1 and big sliding block 6
Wear-resistant block 8 is provided on contact surface, because the big needs of sliding block 6 slidably reciprocate on solid plate 1, wear-resistant block 8 during core pulling
Setting be able to ascend the wearability on 1 surface of solid plate, prevent solid plate 1 and big sliding block 6 from wearing, 7 inclined-plane of small slide block with
Big 6 inclined-plane of sliding block is connected by T-slot to be cooperated, and makes to ensure that glide direction when 7 core pulling of small slide block.
The operating process of the utility model are as follows: shaped article 10 needs after being cooled and shaped between front cavity 12 and rear cavity 11
It demoulds, there are the first back-off 101 and the second back-off 102 between shaped article 10 and front cavity 12 and rear cavity 11, needs two
Secondary core pulling, for mold in die sinking, inclined guide pillar 4 drives big sliding block 6, makes big sliding block 6 backward horizontal under the effect of external spring 15
Movement, and small slide block 7 under the action of inclined guide pillar 4, big shovel base 3, scuppit base 31 and built-in spring 71 along the inclined-plane of big sliding block 6
Core pulling campaign is done, so that shaped article 10 and small slide block 7 are detached from the first back-off 101, big sliding block 6 is under the action of external spring 15
It returns towards the second 102 directions of back-off and does core pulling campaign, so that shaped article 10 and big sliding block 6 are detached from the second back-off 102, thus
Continuity efficiently completes twice core pulling, and shaped article 10 is smoothly demoulded.
