Description

Technical Field

[0001] This utility model relates to the field of molds, and in particular to mold ejection structures. Background Technology

[0002] In the ultra-large integrated die casting process, after die casting is completed, the product needs to be ejected from the cavity. During the ejection process, the drive component of the ejection mechanism abuts against the center of the push plate, causing the push plate to drive the ejector pin to abut against the product, thus ejecting the product from the cavity.

[0003] However, due to the varying clamping forces at different parts of the cavity, some parts emerge first and others later during the center ejection, resulting in an imbalance in the center ejection of the mold. This imbalance causes ejector pin deflection and increased pin wear. The thrust of the ejector pins on the product generates a reaction force, which acts on the push plate that holds the ejector pins, causing deformation of the push plate. This increases the probability of downtime for maintenance and significantly impacts production efficiency. Utility Model Content

[0004] In order to overcome the shortcomings of the existing technology, one of the objectives of this utility model is to provide a mold ejection structure with balanced ejection at the center of the mold.

[0005] One of the objectives of this utility model is achieved through the following technical solution:

[0006] The mold ejection structure includes a mounting plate, a driving component, a mold base plate, a push plate, and ejector pins. The driving component is fixed to the mounting plate. The mold base plate is located between the mounting plate and the push plate. The ejector pins are fixed to the push plate. The mold ejection structure also includes a connecting component, which includes a guide post and a guide sleeve. The guide post and the guide sleeve are respectively fixed to the mounting plate and the push plate. The guide post and the guide sleeve are slidably connected. The guide post or the guide sleeve passes through the mold base plate and is fixed to the push plate. The driving component passes through the mold base plate and abuts against the push plate. The push plate drives the ejector pins to move.

[0007] Furthermore, the connector is parallel to the drive component.

[0008] Furthermore, the projection of the driving member onto the push plate coincides with the centroid of the push plate.

[0009] Furthermore, there are multiple connectors, and the multiple connectors are symmetrically arranged about the drive member.

[0010] Furthermore, the number of connectors is four, and the line connecting the four connectors forms a rectangle.

[0011] Furthermore, the mold base plate is parallel to the push plate.

[0012] Furthermore, the drive element is linear and perpendicular to the push plate.

[0013] Furthermore, there are multiple ejector pins, which are evenly distributed on the push plate.

[0014] Furthermore, the mold base plate is provided with a through hole, which is located on the axis of the driving member, and the end of the driving member passes through the through hole and abuts against the push plate.

[0015] Furthermore, the guide post is made of T10A steel, and the guide sleeve is made of a mixture of copper and graphite.

[0016] Compared with the prior art, the mold ejection structure of this utility model also includes connecting parts, which include guide pillars and guide sleeves. The guide pillars and guide sleeves are respectively fixed to the mounting plate and the push plate. The guide pillars and guide sleeves are slidably connected. The guide pillars or guide sleeves pass through the mold base plate and are fixed to the push plate. The driving component passes through the mold base plate and abuts against the push plate. The push plate drives the ejector pin to move. Through the above design, when the driving component pushes forward, multiple connecting parts will also move forward synchronously and act together on the push plate to ensure the balance of ejection. At the same time, the reaction force of the product will also act along the connecting parts on the mounting plate of the die casting machine to ensure that the push plate will not deform.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0024] Please see Figures 1 to 3 The mold ejection structure of this utility model includes a mounting plate 10, a driving component 20, a mold base plate 30, a push plate 40, an ejector pin 50, and a connecting component 60.

[0025] Mounting plate 10 is used to mount driver component 20.

[0026] The drive element 20 provides the thrust for ejecting the product. In this embodiment, the drive element 20 is a cylinder. The drive element 20 provides the power for linear movement, pushing the push plate 40 and the ejector pin 50 to move. The drive element 20 is perpendicular to the mounting plate 10, and the driving direction of the drive element 20 is the axial direction of the drive element 20.

[0027] The mold base plate 30, as part of the mold, is used to mount the lower mold plate. The mold base plate 30 is parallel to the mounting plate 10. When the driving component 20 is not in operation, it is located between the mounting plate 10 and the mold base plate 30. The mold base plate 30 has through holes 31 and clearance holes 32. The position of the through holes 31 corresponds to the centroid of the push plate 40, allowing the driving component 20 to pass through the through holes 31 and abut against the centroid of the push plate 40. The number and position of the clearance holes 32 correspond to the connecting component 60, allowing the guide posts 61 or guide sleeves 62 of the connecting component 60 to pass through the mold base plate 30 and be fixed to the push plate 40. Multiple clearance holes 32 are symmetrically distributed about the through holes 31.

[0028] The push plate 40 is located on one side of the mold base plate 30 and is parallel to the mold base plate 30. The push plate 40 is used to install the ejector pin 50.

[0029] Ejector pins 50 are used to eject products from the cavity. Ejector pins 50 are fixed to and perpendicular to push plate 40. In this embodiment, there are multiple ejector pins 50, which are evenly distributed on push plate 40.

[0030] The connector 60 includes a guide post 61 and a guide sleeve 62, which are fixed to the mounting plate and the push plate 40, respectively, and are slidably connected. In this embodiment, the guide post 61 is fixed to the mounting plate 10, and the guide sleeve 62 passes through the clearance hole 32 of the mold base plate 30 and is fixed to the push plate 40. The guide post 61 and the guide sleeve 62 are located on the same straight line, and the connector 60 is parallel to the drive component 20. In other embodiments, the guide post 61 can also be designed to be fixed to the push plate 40, and the guide sleeve 62 to the mounting plate 10. The guide post 61 is made of T10A steel, and the guide sleeve 62 is made of a mixed material formed of copper and graphite. The connector 60 is made into a two-section structure for easy assembly and disassembly.

[0031] When using the mold ejection structure, as the drive component 20 pushes forward, multiple connecting components 60 also move forward synchronously, working together on the push plate 40 to ensure balanced ejection. The ejector pin 50 pushes the product out of the cavity, and at the same time, the reaction force of the product also acts along the connecting components 60 on the mounting plate 10 of the die-casting machine, ensuring that the push plate 40 does not deform.

[0032] The above embodiments only illustrate several implementation methods of this utility model, and their descriptions are relatively specific and detailed, but they should not be construed as limiting the scope of the utility model patent. It should be noted that for those skilled in the art, several modifications and improvements can be made without departing from the concept of this utility model. These are all equivalent modifications and improvements made to the above embodiments based on the essential technology of this utility model, and all of these fall within the protection scope of this utility model.
