Description

TECHNICAL FIELD

[0001] The utility model relates to a mould injection technology field especially relates to a kind of ejection mechanism for heat preservation bucket mould injection. BACKGROUND

[0002] The ejection mechanism of heat preservation bucket injection mould is a crucial part of the mould, which is responsible for smoothly ejecting the product from the mould after injection molding. For products such as heat preservation buckets, which have a regular shape and a large volume, ejector pins and push plates are commonly used ejection mechanisms.

[0003] The end of the ejector pin that is used for ejection is commonly referred to as the ejector. This is the part of the ejector pin that directly acts on the product in the injection mould, ejecting it from the mould cavity. During the injection process, the ejector repeatedly enters the cavity and ejects the product, which can cause wear on the contact surface between the ejector and the product. Over time, this wear can increase, affecting the ejection effect.

[0004] Currently, the ejector of the traditional ejector pin on the market cannot be replaced. When the ejector wears out, the entire ejector pin must be replaced. This results in low economic benefits and increased costs for heat preservation bucket injection. SUMMARY

[0005] The utility model aims to solve the problems in the prior art and provides an ejection mechanism for heat preservation bucket mould injection.

[0006] To achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] An ejection mechanism for heat preservation bucket mould injection includes an ejector pin body, a detachable ejector is installed on the top of the ejector pin body, adjustment cavities are formed on both sides of the bottom of the ejector, movable parts are movably arranged in the adjustment cavities, and limit grooves are formed on both sides of the top of the ejector pin body corresponding to the movable parts.

[0008] In addition, the preferred structure is that guide parts are fixedly arranged on the inner walls of both sides of the adjustment cavities, and guide cavities are formed on both sides of the movable parts corresponding to the guide parts.

[0009] In addition, the preferred structure is that a threaded column is fixedly and vertically arranged on the bottom of the ejector, and a threaded groove is formed on the top of the ejector pin body corresponding to the threaded column.

[0010] In addition, the preferred structure is that fixed columns are fixedly and vertically arranged on both sides of the bottom of the ejector, and elastic clamps are mounted on the fixed columns towards the pull plates.

[0011] In addition, preferably, a clamping head is arranged on the elastic clamping piece towards the end of the pull plate, the outer side of the clamping head is a slope, the inner side is a plane, and a through cavity is arranged on the pull plate corresponding to the clamping head.

[0012] In addition, preferably, a spring is arranged on the inner wall of the adjusting cavity, and the other end of the spring is connected with the pull plate.

[0013] The beneficial effects of the present application are as follows: the ejection piece can be installed on the ejector body through the mutual clamping between the threaded column and the threaded groove, and the mutual clamping between the movable piece and the limiting groove can prevent the threaded column from loosening after installation, thereby further improving the installation stability of the ejection piece, and the structure can replace the ejection piece on the ejector body when the ejection piece is severely worn, without replacing the entire ejector body, thereby reducing the cost of injection molding of the insulation barrel.

[0021] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all the embodiments.​​​

[0022] Reference Figure 1-5 An ejection mechanism for the injection molding of a thermos bucket mold includes an ejector rod body 1, a detachable ejector member 2 mounted on the top of the ejector rod body 1, and adjustment cavities 22 defined on both sides of the bottom of the ejector member 2. A movable member 3 is movably disposed within the adjustment cavity 22, and limiting grooves 12 are adapted to correspond to the movable member 3 on both sides of the top of the ejector rod body 1. Elastic clamps 41 are provided on both sides of the bottom of the ejector member 2, and a pull plate 31 is fixedly disposed on the outer side of the movable member 3. A through cavity 32 is adapted to correspond to the elastic clamp 41 on the bottom of the pull plate 31.

[0023] The molded part in the thermos bucket injection mold can be ejected by the ejector 2 on the ejector body 1. It is worth noting that the specific ejection structure of the ejector body 1, the ejector 2 and the thermos bucket injection mold and their working methods are all prior art and therefore will not be described in detail.

[0024] Guide members 23 are fixedly provided on the inner walls of both sides of the adjustment cavity 22, and guide cavities 33 are adapted to correspond to the guide members 23 on both sides of the movable member 3. The arrangement between the guide members 23 and the guide cavities 33 not only guides the movable member 3 but also prevents it from falling out of the adjustment cavity 22.

[0025] The bottom of the ejector 2 is fixed vertically downward with a threaded column 21, and the top of the ejector body 1 is adapted to have a threaded groove 11 for the threaded column 21. By rotating the threaded column 21 and inserting it into the threaded groove 11, the ejector 2 and the ejector body 1 can be fixedly mounted.

[0026] Among them, both sides of the bottom of the ejector 2 are fixed downwardly and vertically provided with fixing columns 4, and elastic clamps 41 are installed on the fixing columns 4 towards the pull plate 31. Through the setting of the fixing columns 4, the installation of the elastic clamps 41 can be achieved.

[0027] A clamping head is provided on one end of the elastic clamping member 41 facing the pull plate 31 , the outer side of the clamping head is an inclined surface, and the inner side is a flat surface, and a through cavity 32 is adapted to fit the clamping head on the pull plate 31 .

[0028] Among them, springs 5 ​​are installed on the inner wall of the adjustment cavity 22, and the other ends of the springs 5 ​​are connected to the pull plates 31. Through the setting of the springs 5, the movable member 3 can be pushed inward, so that the movable member 3 can be firmly clamped in the limiting groove 12.

[0029] In this embodiment, the ejection member 2 on the ejector body 1 can be used to eject the injection molded part in the insulation bucket injection mold. The specific usage is the existing technology, so it will not be described in detail.

[0030] The ejector 2 can be fixedly assembled on the ejector body 1. To install the ejector 2, the user simply pulls the movable members 3 on either side of the bottom of the ejector 2 outward. This compresses the spring 5, and the head of the elastic clamp 4 passes through the inclined surface through the cavity 32 of the pull plate 31. This secures the elastic clamp 41 to the pull plate 31 via the flat surface behind the head, thereby securing the position of the movable member 3. This prevents the movable member 3 from interfering with the subsequent installation of the threaded stud 21.

[0031] The user then simply rotates the threaded stud 21 at the bottom of the ejector 2 into the threaded groove 11 on the ejector body 1 and pulls downward on the elastic clips 41 on either side. This releases the fixed engagement between the elastic clips 41 and the pull plate 31. The pull plate 31 and the movable member 3 are then automatically reset by the elastic force of the spring 5. The bottom of the movable member 3 then automatically returns to its original position within the retaining groove 12. The engagement between the movable member 3 and the retaining groove 12 prevents the threaded stud 21 from loosening from the threaded groove 11, further enhancing the stability of the connection between the ejector 2 and the ejector body 1.

[0032] It is worth noting that when the threaded column 21 is fully rotated and inserted into the threaded groove 11, the limiting grooves 12 on both sides of the push rod body 1 are adapted to be located at the bottom of the adjustment cavity 22, so the movable part 3 will not be unable to be stuck in the limiting groove 12.

[0033] Furthermore, when the ejector 2 becomes worn, the user simply pulls the pull plates 31 on both sides outward, causing the elastic latches 41 to reengage the pull plates 31. This allows the movable member 3 to be pulled out of the retaining groove 12, thereby releasing the engagement between the movable member 3 and the retaining groove 12. The user then simply rotates the ejector 2 to remove the threaded stud 21 at its base from the threaded groove 11 on the ejector body 1, thereby removing the ejector 2. The user can then install a new ejector 2 on the ejector body 1.

[0034] In the present invention, the ejector 2 can be installed on the ejector body 1 by the mutual engagement between the threaded column 21 and the threaded groove 11, and the mutual engagement between the movable part 3 and the limiting groove 12 can prevent the threaded column 21 from loosening after installation, so as to further improve the installation stability of the ejector 2. This structure allows the ejector 2 on the ejector body 1 to be replaced when the ejector 2 is severely worn, without having to replace the entire ejector body 1, so as to reduce the cost of injection molding of the insulation bucket.

[0035] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
