Horizontal drawing and demolding device

Technical Field

The utility model relates to an injection mold field specifically is a violently take out shedder.

Background

The external shapes of medium and large household electrical appliances such as air conditioners, circulating fans and the like are complex, the edges of corresponding inner and outer ornaments need to be spliced through the clamping of a clamping structure, sometimes, the clamping structure needs to be designed to be more complex for ensuring the connection stability between the inner and outer ornaments, and the clamping structure contains more complex inversions corresponding to a die. Such undercuts often contain transverse structural features, and demolding in at least two directions needs to be realized in the mold opening process, which cannot be met by conventional slider demolding structures, so that special demolding structures need to be designed for inner and outer ornament products containing complex buckle structures.

Disclosure of Invention

The utility model aims to provide a violently take out shedder to the interior outer gadget product that contains complicated buckle structure.

In order to realize the above object, the utility model provides a violently take out shedder, movable mould board including the rectangle, movable mould benevolence is equipped with at the middle part to the movable mould board, movable mould benevolence includes the shaping boss, be equipped with the side profile that is on a parallel with the movable mould board minor face on the shaping boss, its special character lies in, be equipped with violently taking out the mechanism in the outside of side profile on the movable mould board, violently take out the mechanism including can following the seat that slides of movable mould board length direction reciprocating motion, violently take out the mechanism still including the level and wear to locate the oblique guide arm on sliding the seat, oblique guide arm sets up the shaping head in the one end towards the shaping boss, slide the seat inside be equipped with oblique guide hole with oblique guide arm complex, slide the seat tip be equipped with shaping head complex storage tank. The forming head is provided with a dovetail groove extending along the width direction of the movable template on the end surface. The bottom surface of the forming head is flush with the bottom surface of the sliding seat, the bottom surface of the forming head is provided with a guide block, the movable die core is provided with a guide transverse groove matched with the guide block, and the guide transverse groove extends along the width direction of the movable die plate.

According to the scheme, in the die closing state, the forming head is integrally embedded into the accommodating groove and connected with the sliding seat into a whole, during demolding, the sliding seat moves back to the movable die core and transmits the movable die core to the forming head through the inclined guide rod, and the forming head moves along the width direction of the movable die plate under the guide of the guide block and the guide transverse groove, so that demolding of the dovetail groove inner buckle structure is realized, and the dovetail groove inner buckle structure is gradually separated from the accommodating groove. When the sliding seat moves towards the movable mould core, the inclined guide rod drives the forming head, the forming head can reset along the width direction of the movable mould plate under the guide of the guide block and the guide transverse groove and is embedded into the containing groove again, and therefore the transverse drawing mechanism can realize local transverse drawing and demoulding of products containing complex buckle structures.

The further scheme is that one end of the oblique guide rod back to the forming boss is located outside the sliding seat, the movable template is provided with a side abutting seat matched with the oblique guide rod on the short side, the side abutting seat comprises a side baffle perpendicular to the oblique guide rod, and the oblique guide rod abuts against the side baffle at one end of the oblique guide rod back to the forming boss.

It is from top to bottom visible, above-mentioned side supports the seat all the time with oblique guide arm outer end butt, consequently introduces the side and supports the cooperation that the seat can strengthen between oblique guide arm and the movable mould board, can also guide oblique guide arm along the translation of side shield.

The further scheme is that the side molded surface is an inclined surface, a guide longitudinal groove matched with the guide block is further arranged on the movable die core, the guide transverse groove and the guide longitudinal groove are distributed in an L shape, and the guide longitudinal groove is vertically communicated with the guide transverse groove. The side support seat further comprises a base block, a mounting groove is formed in one side, facing the inclined guide rod, of the base block, and the side baffle is located in the mounting groove. The side support seat further comprises a reset component which is connected with the side baffle and the base seat block, and the reset component is positioned in the mounting groove.

Therefore, as the side molded surface is an inclined surface, the forming head needs to retreat along the length direction of the movable mould plate after completing the transverse pumping action to make the straight-top demoulding movable space of the product out, the movable mould core needs to correspondingly introduce the guide longitudinal groove to guide the forming head to longitudinally retreat, and the other side abutting seat needs to reserve a retreat space for the inclined guide rod in the length direction of the movable mould plate and assist the restoration of the inclined guide rod.

The further scheme is that the reset assembly comprises a guide rod and a reset spring, wherein the guide rod is perpendicular to the side baffle, an external thread is arranged at the first end of the guide rod, a screw hole is formed in one side of the side baffle, which is back to the inclined guide rod, the guide rod is in threaded connection with the side baffle at the first end, and the second end of the guide rod penetrates out of the base block and is provided with a limit cap. Reset spring cover is located on the guide bar, and reset spring first end and side shield butt, reset spring second end and base piece are at mounting groove tip butt.

Therefore, the reset assembly composed of the guide rod and the reset spring is simple in structure, and can provide elastic support for the inclined guide rod and play a role in guiding the inclined guide rod.

The further scheme is that in the vertical direction, the thickness of the inclined guide rod is equal to that of the side baffle plate, and the height of the installation groove is equal to that of the side baffle plate.

It is thus clear that oblique guide arm, side shield and mounting groove are unanimous at the ascending size of vertical side, consequently the offside supports can guarantee after the setting position of seat optimizes that the mounting groove is spacing in vertical side to oblique guide arm outer end to the side supports the seat and also can play the guide effect to the removal of side shield.

The further proposal is that the side baffle is provided with anti-skid lines at one side facing the inclined guide rod.

It is from top to bottom visible, introduce the cooperation that anti-skidding line can strengthen oblique guide arm outer end and side shield, guarantee oblique guide arm at the translation in-process with the stable butt between the side shield.

The further proposal is that when the guide block is positioned at the end part of the guide transverse groove, the end surface of the forming head is flush with the end surface of the sliding seat.

It is thus clear that can make it play the positioning action to the shaping head under the compound die state through the size of optimizing the direction cross slot, guarantee the precision of product on local shape and size.
