Description

Technical Field

[0001] This utility model relates to the technical field of mold demolding mechanism structure, and in particular to a mold demolding mechanism. Background Technology

[0002] Molds are various molds and tools used in industrial production to obtain desired products through methods such as injection molding, blow molding, extrusion, die casting, forging, smelting, and stamping. In short, a mold is a tool used to make shaped objects. This tool is composed of various parts. Among the components, the mold needs to use a demolding mechanism. The demolding mechanism can lift the object processed by the mold, so that it can be easily demolded and unloaded.

[0003] A search revealed that authorization announcement number CN213082226U discloses an ejection structure for an injection mold, including a lower mold base, guide rods, a mounting plate, and a top plate. Four sets of guide rods are vertically fixed at the four corners of the top of the lower mold base, and a top plate is fixed at the top of each guide rod. Mounting grooves are formed at the four corners of the mounting plate, and an upper mold base is located at the bottom of the mounting plate. An injection cavity is formed at the top of the lower mold base, and a lifting cavity is formed directly below the injection cavity. A lifting structure is provided inside the lifting cavity, and several sets of ejector rods are formed at the top of the lifting structure. A mounting plate is fixed at the top of each ejector rod, and a top piece is provided on the side of the mounting plate away from the ejector rod. An installation cavity for installing the top piece is formed at the bottom of the injection cavity. This ejection structure for an injection mold is reasonably designed and can effectively eject the molded part after injection, thus preventing the molded part from getting stuck in the injection cavity. It also facilitates the replacement of the top piece and is suitable for widespread use.

[0004] Existing mold demolding mechanisms are complex in structure and have multiple operating trajectory controls, which makes the demolding mechanism less accurate during operation and prone to damage. Therefore, there is an urgent need in the market for a mold demolding mechanism to solve these problems. Utility Model Content

[0005] The purpose of this utility model is to provide a mold release mechanism to solve the problems mentioned in the background art, such as the complex structure and multiple running trajectory control of the existing mold release mechanism, which makes the release mechanism less accurate during operation and prone to damage.

[0006] To achieve the above objectives, the present invention provides the following technical solution:

[0007] A mold release mechanism includes a mounting base, a lead screw motor mounted below the mounting base, a support rod mounted above the mounting base, a transverse mounting seat mounted above the support rod, a rotating lead screw mounted between the transverse mounting seat and the mounting base, a lead screw slide mounted outside the rotating lead screw, mounting support seats mounted on both sides of the lead screw slide, a limit groove provided inside the mounting support seat, a limit mounting groove provided at one end of the limit groove, a threaded mounting groove provided at the lower end of the limit mounting groove, and a push rod mounted above the mounting support seat.

[0008] By adopting the above technical solution, the ejector pin can be easily installed, allowing it to move under the drive of the device, thereby enabling the mold to have a good ejection effect and to eject and demold the processed items.

[0009] Furthermore, the mounting base has four mounting holes inside, which are symmetrical about the vertical center line of the mounting base.

[0010] By adopting the above technical solution, the device can be easily installed and fixed through the mounting holes provided on the mounting base.

[0011] Furthermore, a fixed seat is provided at the upper end of the lead screw motor, and the fixed seat is fixedly connected to the mounting base by a first fixing screw.

[0012] By adopting the above technical solution, the lead screw motor can be easily installed and fixed. The lead screw motor can control the rotation of the lead screw, thereby enabling the push rod to move.

[0013] Furthermore, two support rods are provided. The upper end of the support rod is welded to the transverse mounting seat, and the lower end of the support rod is welded to the mounting base. One end of the support rod passes through the limiting groove provided in the mounting support seat and extends to the outside of the limiting groove.

[0014] By adopting the above technical solution, the support rod can support the installation of the horizontal mounting base, and at the same time, the mounting support base can be limited to move along the direction of the support rod.

[0015] Furthermore, the rotating lead screw is configured correspondingly to the lead screw motor, and the lead screw slide is configured correspondingly to the rotating lead screw.

[0016] By adopting the above technical solution, this configuration enables the lead screw motor to control the rotation of the lead screw, and the rotation of the lead screw motor enables the lead screw slide to move.

[0017] Furthermore, two mounting supports are provided, one end of which is provided with a fixed end, and the fixed end is provided with a fixing screw hole inside. The fixed end is fixedly connected to the lead screw slide by a second fixing screw.

[0018] By adopting the above technical solution, the mounting support and the lead screw slide can be easily installed and fixed.

[0019] Furthermore, several push rods are provided, and a threaded mounting seat is provided at the lower end of each push rod. The threaded mounting seat is provided in correspondence with the threaded mounting groove, and one end of the threaded mounting seat is located inside the threaded mounting groove.

[0020] By adopting the above technical solution, the ejector pin can effectively eject and demold the finished product during mold processing.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] 1. This utility model enables the lead screw to rotate by turning on the lead screw motor, thereby allowing the lead screw slide to drive the mounting support to move. This, in turn, causes the mounting support to push the ejector rod to move, enabling the ejector rod to eject the material processed by the mold and demold it. At the same time, the threaded mounting seat and threaded mounting groove are correspondingly set to facilitate the installation of the ejector rod, and when the ejector rod is damaged, it can be easily disassembled and replaced.

[0023] 2. The ejector rod of this utility model can be easily installed by means of a threaded mounting seat and a threaded mounting groove corresponding to the mounting support seat. When the ejector rod is damaged, it can be easily disassembled and replaced. When moving, one end of the support rod passes through the limiting slide groove set in the mounting support seat. This allows the mounting support seat to be positioned and moved along the direction of the support rod, avoiding deviation during the movement, which would affect the working effect of the demolding mechanism.

Mounting support seats 8 are mounted on both sides of the lead screw slide 7. A limiting groove 803 is provided inside the mounting support seat 8. A limiting mounting groove 804 is provided at one end of the limiting groove 803, and a threaded mounting groove 805 is provided at the lower end of the limiting mounting groove 804. A top rod 10 is mounted above the mounting support seat 8. There are two support rods 4. The upper end of the support rod 4 is symmetrical about the vertical center line of the mounting base 1. The mounting base 5 is welded together, and the lower end of the support rod 4 is welded together with the mounting base 1. One end of the support rod 4 passes through the limiting slide groove 803 provided in the mounting support base 8 and extends to the outside of the limiting slide groove 803. The upper end of the lead screw motor 2 is provided with a fixed seat 201. The fixed seat 201 is fixedly connected to the mounting base 1 by the first fixing screw 3. The rotating lead screw 6 is correspondingly provided with the lead screw motor 2, and the lead screw slide 7 is correspondingly provided with the rotating lead screw 6. The installed lead screw motor 2 enables the rotating lead screw 6 to rotate, thereby enabling the lead screw slide 7 to drive the mounting support base 8 to move.

It should be noted that, in order to save space and highlight the innovative elements of this patent, such as the specific working principle and working process of the mold, it will not be described in detail in this patent.

[0031] See Figure 1 , Figure 2 , Figure 3 and Figure 4 There are two mounting supports 8. One end of the mounting support 8 is provided with a fixed end 801. The fixed end 801 is provided with a fixing screw hole 802. The fixed end 801 is fixedly connected to the lead screw slide 7 by a second fixing screw 9. Several push rods 10 are provided.

At the same time, the threaded mounting seat 1001 and the threaded mounting groove 805 are correspondingly provided to facilitate the installation of the push rods 10. When the push rods 10 are damaged, they can be easily disassembled and replaced.

[0032] Working principle: In use, turning on the lead screw motor 2 causes the lead screw 6 to rotate, which in turn causes the lead screw slide 7 to move the mounting support 8. This causes the mounting support 8 to push the ejector rod 10, allowing the ejector rod 10 to eject the material processed by the mold and demold. The ejector rod 10 is easily installed via a threaded mounting seat 1001 and a corresponding threaded mounting groove 805 on the mounting support 8. Damaged ejector rod 10 can be easily disassembled and replaced. During movement, one end of the support rod 4 passes through the limiting groove 803 on the mounting support 8, allowing the mounting support 8 to be positioned and moved along the direction of the support rod 4, preventing deviation during movement and ensuring the demolding mechanism's effectiveness.
