Background

When a lamp housing product with a plurality of inverted buckles is processed, as shown in fig. 1, although a structure of a common sliding block and an inclined top is adopted, the die can be demolded, but the following problems mainly exist:

1. the oblique ejection is arranged at the lower end of the large sliding block, and the sliding block is inserted into the oblique ejection sealing glue to easily produce burrs.

2. The inclined top is arranged at the lower end of the sliding block, and the moving distance of the sliding block is large, so that the large sliding block is unstable in cooperation.

3. The stroke of the sliding block is increased, the die carrier is also increased, the injection molding machine is increased, and the injection molding cost is affected.

4. Two pitched roofs are generally required, but the space and the position are smaller, and the stability of the pitched roof design is poorer.

5. And the water outlet position of the connector structure can be blocked by the inclined top, so that the cooling of the product is affected.

The utility model aims at the problems and provides a slide block combined core-pulling structure which can simplify the core-pulling structure, so that a die can be produced in an injection molding machine with a common specification, and the efficiency is improved.

The utility model adopts the following technical scheme: a combined core pulling structure of a sliding block comprises a die core and a large sliding block and is characterized in that a small sliding block and a small sliding block pulling mechanism are arranged in the large sliding block, and after the large sliding block moves outwards for a certain distance, the small sliding block pulling mechanism pulls the small sliding block to move outwards in the same direction.

Preferably, the small slide block pulling mechanism comprises a small slide block draw hook arranged at the bottom of the small slide block, and the small slide block is obliquely arranged in the large slide block.

Preferably, the small slider forms a section of travel groove at the bottom, and the small slider drag hook forms a convex hook at the front end to be clamped into the travel groove.

Preferably, the small slider drag hook is provided with a mounting hole in the center of the outer end, and the small slider drag hook is positioned and mounted on the large slider through a connecting pin.

Preferably, the small slide blocks are provided with pressing blocks at two sides, and the pressing blocks are fixed on the die core.

Preferably, the large slide block is provided with an inclined guide post, and the large slide block is driven to move by the inclined guide post.

The utility model integrates the small back-off demoulding structure into the large slide block, so that the mould structure is more compact and more reliable. The die-bumping device is simple in overall structure, convenient to assemble and disassemble and capable of effectively avoiding die-bumping risks.

Detailed Description

The utility model will be further illustrated with reference to specific examples.

The combined core pulling structure of the sliding block shown in the figures 2-6 comprises a die core 10 and a large sliding block 1, wherein a small sliding block 2 and a small sliding block pulling mechanism are arranged in the large sliding block 1, and after the large sliding block 1 moves outwards for a certain distance, the small sliding block 2 is pulled to move outwards in the same direction by the small sliding block pulling mechanism.

In one embodiment, the small slide pulling mechanism comprises a small slide draw hook 4 arranged at the bottom of the small slide 2, and the small slide 2 is obliquely arranged in the large slide 1.

Specifically, the small slider 2 forms a section of travel groove 8 at the bottom, and the small slider drag hook 4 forms a convex hook 9 at the front end to be clamped into the travel groove 8. When the large slide block moves outwards, the small slide block drag hook moves in the travel groove 8 until the small slide block drag hook slides to the tail end of the travel groove 8 and then drives the small slide block to move outwards together, so that indirect linkage is formed.

Preferably, the small slider drag hook can also be arranged at the side part of the lower part of the small slider, the two sides of the small slider drag hook are symmetrically arranged to position the two sides of the slider, the two sides of the small slider drag hook are also provided with sliding grooves, and the front part of the small slider drag hook is clamped into the sliding grooves.

In one embodiment, the small slider drag hook 4 is provided with a mounting hole at the center of the outer end, and the small slider drag hook 4 is positioned and mounted on the large slider 1 through the connecting pin 6. The small slider drag hook is fixed on the large slider, and the large slider drives the small slider drag hook to move.

In one embodiment, the small slide block 2 is provided with pressing blocks 7 at two sides, and the pressing blocks 7 are fixed on the die core 10. The small sliding block is limited through the two side pressing blocks, so that the small sliding block is prevented from being driven to act when the large sliding block moves in the first stage.

Specifically, the large slide block 1 is provided with an inclined guide post 3, and the large slide block 1 is driven to move by the inclined guide post 3. The large sliding block is driven to move mainly through the inclined guide post 3, and a reset spring 11 is further arranged in the large sliding block, so that the large sliding block is convenient to reset.

The working process of the utility model is as follows: the lamp housing product 5 is formed in the die core 10 and the large slide block 1, the large slide block 1 is driven to move by the inclined guide post 3, the small slide block 2 is fixed on the die core because the pressing block 7 is fixed, the large slide block 1 moves, the small slide block draw hook 4 is fixed on the large slide block, so that synchronous movement is realized, when the large slide block 1 moves to 30mm, the small slide block draw hook 4 bumps into the small slide block 2, the small slide block 2 moves 5mm along with the large slide block 1 under the driving of the small slide block draw hook 4, and all inversions are separated from the die. As shown in fig. 6, the large slider and the small slider are drawn out in different directions, and thus the small slider is obliquely disposed inside the large slider.

It is to be understood that these examples are illustrative of the present utility model and are not intended to limit the scope of the present utility model. Further, it is understood that various changes and modifications may be made by those skilled in the art after reading the teachings of the present utility model, and such equivalents are intended to fall within the scope of the claims appended hereto.
