Description
Technical Field
The utility model belongs to the technical field of the injection mold technique and specifically relates to a luggage-boot lid bumper switching-over core structure that contracts.
Background
In general, a plurality of sensing holes are formed in the area of the trunk lid, and the sensing holes need to be buckled and pulled out reversely when the mould is opened, so that the trunk lid needs to be retracted and pulled out.
However, the existing shrinkage core-pulling mechanism is relatively complex, occupies a large space, and is easy to damage a product during core pulling, so that the existing shrinkage core-pulling mechanism is to be further improved.
SUMMERY OF THE UTILITY MODEL
The to-be-solved technical problem of the utility model is: the utility model provides a trunk lid bumper switching-over core structure that contracts has characteristics such as simple structure, long service life.
The utility model provides a technical scheme that its technical problem adopted is: a reversing core-contracting structure of a bumper of a trunk lid comprises a fixed template and a movable template, wherein the fixed template is arranged at the top, a left sliding block and a right sliding block are arranged between the fixed template and the movable template, and the left sliding block and the right sliding block are respectively arranged on the upper end surface of the movable template in a sliding manner; the left sliding block and the right sliding block respectively slide on the movable template through the guidance of the inclined guide columns; the fixed die plate is also provided with a pressing mechanism, and the pressing mechanism comprises a fixed block and a positioning pin connected with the fixed block through a spring; the upper end surface of the sliding block is provided with a groove, and the positioning pin is inserted into the groove; and one end of the sliding block facing the mold core is provided with a back-off core.
Further say, the upper end of die holder be provided with the pouring cover, the upper end of core extend to the lower terminal surface of die holder and be located between left and right slider.
Still further say, the movable mould board on be provided with oblique guide post groove, the lower part of oblique guide post insert in oblique guide post inslot to one side.
The beneficial effects of the utility model are that, solved the defect that exists among the background art, simple structure has reduced manufacturing procedure, has improved whole production machining efficiency, can satisfy the standard that the customer accepted the product, has very big promotion to mould life and product percent of pass.
Drawings
Fig. 1 is a schematic structural view of a preferred embodiment of the present invention;
in the figure: 1. fixing a template; 2. moving the template; 3. a left slider; 4. a right slider; 5. an oblique guide post; 6. a fixed block; 7. a spring; 8. positioning pins; 9. a groove; 10. a back-off core; 11. pouring a sleeve; 12. an oblique guide post slot; 13. and (3) a core.
Detailed Description
The invention will now be described in further detail with reference to the drawings and preferred embodiments. These drawings are simplified schematic drawings and illustrate the basic structure of the present invention only in a schematic manner, and thus show only the components related to the present invention.
The reversing core-contracting structure of the bumper of the trunk lid shown in fig. 1 comprises a fixed template 1 and a movable template 2, wherein the fixed template 1 is arranged at the top, a left slide block 3 and a right slide block 4 are arranged between the fixed template and the movable template, and the left slide block and the right slide block are respectively arranged on the upper end surface of the movable template 2 in a sliding manner; the fixed template is provided with an inclined guide post 5, and the left sliding block and the right sliding block respectively slide on the movable template through the guide of the inclined guide post 5; the fixed die plate is also provided with a pressing mechanism, and the pressing mechanism comprises a fixed block 6 and a positioning pin 8 connected with the fixed block 6 through a spring 7; the upper end face of the sliding block is provided with a groove 9, and the positioning pin is inserted into the groove; the end of the slide facing the core 13 is provided with a back-off core 10. The upper end of the fixed die plate 1 is provided with a pouring sleeve 11, and the upper end of the mold core 13 extends to the lower end face of the fixed die plate and is positioned between the left sliding block and the right sliding block. An inclined guide post groove 12 is formed in the movable template, and the lower portion of the inclined guide post is obliquely inserted into the inclined guide post groove.
The movable template approaches to the fixed template, and the slide blocks are guided to move through the inclined guide columns, so that the left slide block and the right slide block approach relatively until the slide blocks are pressed by the pressing mechanism, and the die assembly is completed; then adopt the pouring cover directly to mould plastics to the mould cavity, after the completion of moulding plastics, the movable mould board leaves and drives the slider and withdraw for the back-off core directly deviates from the product, and not only easy operation is convenient like this, can reduce the process greatly moreover, improves holistic production machining efficiency.
While the foregoing is directed to embodiments of the present invention, other and further embodiments of the invention may be devised without departing from the basic scope thereof, and the scope thereof is determined by the claims that follow.
