Description

Mold opening and closing mechanism of license plate lamp base mold
Technical Field
The invention belongs to the technical field of machinery, and relates to a mold opening and closing mechanism of a base mold of a license plate lamp.
Background
The license plate lamp base is made of plastic materials, and the license plate lamp base with a complex structure can be rapidly formed through a license plate lamp base die.
The forming die comprises an upper die and a lower die, and a forming cavity matched with the license plate lamp base is formed between the upper die and the lower die after the upper die and the lower die are clamped.
It can be seen that whether the upper die and the lower die are buckled and connected accurately determines the molding quality of the license plate lamp base directly.
In order to solve the problems, the conventional forming die is generally provided with an inclined ejection mechanism, wherein the inclined ejection mechanism comprises an inclined guide groove obliquely arranged on the die, a spring and an inclined ejection connected in the inclined guide groove, and the inclined ejection is ejected mainly by means of spring force and is clamped between an upper die body and a lower die body after being stretched out.
However, the existing forming die is poor in stability, and after foreign matters such as scraps enter the inclined guide groove, the inclined ejection mechanism is blocked and cannot eject, so that the workpiece and the die are damaged, and the stability is poor.
Disclosure of Invention
The invention aims to solve the problems in the prior art and provide a mold opening and closing mechanism of a base mold of a license plate lamp, which has high stability and compact structure.
The aim of the invention can be achieved by the following technical scheme:
the mold opening and closing mechanism of the license plate lamp base mold comprises an upper mold body and a lower mold body, wherein the upper mold body is connected with the lower mold body in a buckling manner and forms a molding cavity for molding the license plate lamp base between the upper mold body and the lower mold body, the mold opening and closing mechanism is characterized by being positioned between the upper mold body and the lower mold body and comprising an inclined top component, a limiting block and a draw hook, the upper mold body is provided with a connecting hole which is obliquely arranged and matched with the inclined top component, the limiting block is fixedly connected with the upper mold body, the inclined top component is connected with the connecting hole, the inclined top component has a downward movement trend, the inner side of the inclined top component is abutted against the limiting block, the draw hook is fixedly connected with the lower mold body, the inner side of the lower end of the inclined top component is abutted against the limiting block after the upper mold body and the lower mold body are matched, the draw hook is connected with the outer side of the inclined top component in a buckling manner,
after the lower die body is separated from the upper die body, the oblique top assembly moves downwards to the inner side of the middle part of the oblique top assembly to lean against the limiting block, and the drag hook is separated from the oblique top assembly.
Under the action of the mold opening and closing mechanism of the base mold of the license plate lamp, the upper mold body and the lower mold body which are mutually buckled and connected can be stably connected.
Specifically, when the upper die body and the lower die body are in a die closing state, the drag hook plays a role in ensuring that the inclined top is reliably pulled out when the die is opened, and the phenomenon that the inclined top cannot be ejected after foreign matters enter the inclined guide groove is avoided.
When demoulding, the upper mould body moves upwards, and then the inclined top assembly moves downwards relative to the upper mould body. Because the inclined top component is obliquely arranged, the inclined top component can be separated from the drag hook after moving downwards, and the stable separation of the upper die body and the lower die body can be ensured.
Because the upper die body is provided with the connecting hole which is obliquely arranged, and the inclined top component matched with the connecting hole is positioned at the connecting hole, the inclined top component can be stably inclined and translated relative to the upper die body.
In the above-mentioned mold opening and closing mechanism of license plate lamp base mold, the oblique top assembly includes roof and spring, and above-mentioned roof is long platy and roof wears to establish the connecting hole department at last die body, and the both ends of above-mentioned spring are respectively used in last die body and roof, and the roof has the trend of moving down under the elasticity effect of spring.
The top plate has a tendency to stably move downwards towards the lower part of the upper die body under the action of the elastic force of the spring.
In the mold opening and closing mechanism of the license plate lamp base mold, the top plate is provided with a spring hole extending from the upper end to the middle part, and the spring is embedded in the spring hole.
The spring holes provide sufficient positions for the springs to set, avoiding the springs from taking up excessive space.
In the above-mentioned mold opening and closing mechanism of license plate lamp base mold, the top plate is provided with a plurality of spring holes along the width direction, and each spring hole is internally provided with a spring.
The springs are arranged in the spring holes in one-to-one correspondence with the spring holes, and the top plate can stably move downwards when the structure is adopted.
In the above-mentioned mold opening and closing mechanism of license plate lamp base mold, the top plate inner side is provided with a concave limit groove, the side part of the limit block is embedded in the limit groove, and the height dimension of the limit groove from top to bottom is larger than that of the limit block.
The limiting groove is arranged to enable the top plate to move in a set travel range, so that the top plate is prevented from being separated from the upper die body due to transitional movement.
In the above-mentioned mold opening and closing mechanism of license plate lamp base mold, the lower end of the top plate is provided with a guiding part protruding outwards, and the side part of the draw hook is abutted against the guiding part.
Because the side part of the draw hook is contacted with the guide part, the structure plays a proper guide role, and the draw hook can be stably contacted and connected with the nail plate.
In the mold opening and closing mechanism of the license plate lamp base mold, the draw hook comprises a blocky body and a hook body in a hook shape, the hook body is positioned at the edge of the body, and the body is fixedly connected to the lower mold body through a fastener.
The body is provided with enough positions for the connection of the fasteners, and the hook body can be stably buckled and connected on the top plate.
In the mold opening and closing mechanism of the license plate lamp base mold, the body and the hook body are of an integrated structure.
Such a structure can appropriately increase its compactness.
In the above-mentioned mold opening and closing mechanism of license plate lamp base mold, the end of the top plate lower end at the guiding part is provided with a concave buckling notch, the upper end of the draw hook is provided with a hook body matched with the buckling notch, when the upper mold body and the lower mold body keep a mold closing state, the lower end of the top plate is abutted against the limiting block and the hook body of the draw hook is embedded in the buckling notch of the top plate.
After the hook body of the draw hook is embedded into the buckling notch of the top plate, the draw hook can be connected with the top plate in a stable buckling way.
In the mold opening and closing mechanism of the license plate lamp base mold, the top plate, the spring and the draw hook form a clutch unit, the number of the clutch units is two, and the two clutch units are symmetrically arranged on two sides of the limiting block.
The clutch units symmetrically arranged on two sides of the limiting block can further improve connection stability of the upper die body and the lower die during buckling.
Compared with the prior art, because the roof moves obliquely along the direction of the connecting hole on the upper die body in the die opening and closing mechanism of the base die of the license plate lamp, the inner side of the roof always has a trend of leaning on the limiting block under the action of the elastic force of the spring, and the structure can ensure that the draw hook is stably buckled and connected on the roof in a die closing state, and the draw hook can be stably separated from the roof in a die releasing state, so that the stability is higher, and the injection molding yield can be effectively improved.
Meanwhile, only the drag hook is arranged on the lower die body, other parts of the mechanism are arranged on the upper die body, and the whole structure is compact and has high practical value.
Of course, the mold opening and closing mechanism can also prevent the upper mold body from moving left and right relative to the lower mold body, and further improves the stability of the mold opening and closing mechanism.
