Description

Technical Field

[0001] This utility model relates to the field of mold manufacturing technology, specifically to a mold frame ejector plate anti-jamming guide structure. Background Technology

[0002] In the mold manufacturing process, the ejector plate of the mold base plays a crucial role. After molding processes such as injection molding or die casting are completed, the molded product needs to be ejected from the mold cavity by the ejector plate. However, existing mold base ejector plates often experience jamming problems during operation. On the one hand, during long-term reciprocating motion, friction between the ejector plate and the guide components causes wear on the guide components, reducing guiding accuracy. As wear intensifies, the gap between the ejector plate and the guide components increases, making it prone to wobbling and subsequently causing jamming during ejection. On the other hand, the mold is subjected to various complex forces during operation, such as injection pressure and clamping force. These forces may cause a certain degree of deformation in the mold base. Deformation of the mold base can cause the installation position of the ejector plate to shift, affecting the originally precise guiding structure. As a result, the ejector plate cannot move along the correct trajectory during ejection, thus causing jamming.

[0003] The jamming of the ejector plate not only affects the smooth demolding of the product and reduces production efficiency, but may also lead to product damage, increase production costs, and in severe cases, even damage related parts of the mold, requiring repair or replacement, further prolonging downtime and causing economic losses to the enterprise. Therefore, there is an urgent need for a mold base ejector plate anti-jamming guide structure to overcome the above defects. Utility Model Content

Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model. Therefore, the following detailed description of the embodiments of this utility model provided in the accompanying drawings is not intended to limit the scope of the claimed utility model, but merely represents selected embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0020] This utility model provides, for example Figure 1-4 As shown, a mold frame ejector plate anti-jamming guide structure includes an upper mold frame assembly 1, a lower mold frame assembly 2, a T-shaped frame 3, and an arc-shaped ejector rod 4. The upper mold frame assembly 1 is located on top of the lower mold frame assembly 2, the T-shaped frames 3 are located on both sides of the lower mold frame assembly 2, and the arc-shaped ejector rod 4 is located on top of the T-shaped frames 3. The upper mold frame assembly 1 includes an upper fixed plate 11, a female template 12, a guide sleeve 13, an arc-shaped insert rod 14, a connecting rod 15, and a lower pressure frame 16. The lower mold frame assembly 2 includes a lower fixed plate 21, a lower ejector plate 22, an upper ejector plate 23, a connecting rod 24, a mold foot 25, a sliding rod 26, an ejector pin body 27, a male template 28, a guide post 29, a spring 291, a ball bearing slide 292, an annular slide rail 293, and a fixed column 294.

[0021] More specifically, the description of the upper mold frame assembly 1, lower mold frame assembly 2, T-shaped frame 3, and arc-shaped ejector rod 4 lays the foundation for the entire anti-jamming guide structure. This clear structural division helps to achieve collaborative work between the components. Each component undertakes different functions in the subsequent mold operation process, jointly ensuring the smooth operation of the ejector plate and reducing the occurrence of jamming.

[0022] In some embodiments, a mother template 12 is fixedly installed at the bottom of the upper fixing plate 11, a connecting rod 15 is fixedly installed on the front of the mother template 12, a lower pressure frame 16 is fixedly installed on both sides of the front of the connecting rod 15, and an arc-shaped insert rod 14 is fixedly installed on both sides of the mother template 12. More specifically, through the connection relationship of each component in the upper mold frame assembly 1, the upper fixing plate 11 provides a stable installation foundation for the mother template 12, ensuring the stability of the mother template 12 during the mold operation process.

[0023] In some embodiments, guide sleeves 13 are fixedly installed around the bottom of the female template 12, a male template 28 is provided at the bottom of the female template 12, guide pins 29 are slidably connected around the top of the male template 28, and mold feet 25 are fixedly installed on both sides of the bottom of the male template 28. More specifically, by installing the mold feet 25 at the bottom of the male template 28, stable support is provided for the male template 28, ensuring the stability of the male template 28 when subjected to external forces such as injection pressure, thereby indirectly ensuring the stable operating environment of the ejector plate and reducing the possibility of jamming.

[0024] In some embodiments, a lower fixing plate 21 is fixedly installed at the bottom of the mold foot 25, a lower ejector plate 22 is provided at the top of the lower fixing plate 21, and an upper ejector plate 23 is provided at the top of the lower ejector plate 22. Sliding rods 26 are slidably connected around the interior of the lower ejector plate 22 and the upper ejector plate 23. More specifically, by setting the lower fixing plate 21 as a basic support component, an installation platform is provided for the lower ejector plate 22 and the upper ejector plate 23. The lower ejector plate 22 and the upper ejector plate 23 are slidably connected by the sliding rods 26, which play a guiding and supporting role, so that the lower ejector plate 22 and the upper ejector plate 23 can slide smoothly along the sliding rods 26 during the ejection process, avoiding jamming due to shaking or deviation. This structural design helps to ensure the smoothness and accuracy of the ejection action and improve the ejection efficiency.

[0025] In some embodiments, the top of the slide rod 26 is fixedly connected to the bottom of the male template 28, the bottom of the slide rod 26 is fixedly connected to the top of the lower fixed plate 21, and connecting rods 24 are fixedly installed on both sides of the upper ejector plate 23. The relatively close side of the T-shaped frame 3 is fixedly connected to the outer side of the lower ejector plate 22. More specifically, by setting the connection relationship between the slide rod 26 and the male template 28 and the lower fixed plate 21, the stability of the entire mold structure is enhanced. The connection between the T-shaped frame 3 and the lower fixed plate 21 adds additional support and guide points to the entire mold frame structure, which may provide lateral support or guidance to the ejector plate during the ejection process, preventing the ejector plate from tilting or jamming under lateral force.

[0026] In some embodiments, both sides of the male template 28 are rotatably connected to the inner side of the arc-shaped top rod 4 via torsion springs. Both sides of the upper ejector plate 23 and the lower ejector plate 22 are fixedly installed with annular slide rails 293. A ball bearing slide 292 is slidably connected inside the annular slide rail 293. A fixing column 294 is fixedly installed inside the ball bearing slide 292. More specifically, the cooperation between the annular slide rail 293 and the ball bearing slide 292 provides low-friction and high-precision guidance for the sliding of the ejector plate in a specific direction. The fixing column 294 ensures the stable installation of the annular slide rail 293, so that the ejector plate can smoothly eject under this guiding structure, reducing jamming caused by excessive friction or inaccurate guidance.

[0027] In some embodiments, the bottom of the fixed column 294 is fixedly connected to the interior of the lower fixed plate 21, the surface of the slide rod 26 is fitted with a spring 291, and the top of the lower ejector plate 22 is fixedly mounted with uniformly distributed ejector pin bodies 27. More specifically, by uniformly distributing the ejector pin bodies 27 on the lower ejector plate 22, an ejection force can be uniformly applied to the product during ejection, so that the product can be smoothly demolded, avoiding product deformation or jamming in the mold due to uneven ejection force, indirectly ensuring the normal operation of the ejector plate and preventing jamming.

[0028] Working principle:

[0029] Step 1: The upper mold frame assembly 1 moves downward and approaches the lower mold frame assembly 2. The upper fixed plate 11 drives the female mold plate 12 to move downward. The guide sleeves 13 around the bottom of the female mold plate 12 slide along the guide pins 29 around the top of the male mold plate 28 to achieve precise guidance and ensure accurate mold closing of the upper and lower mold frame assemblies. At the same time, when the arc-shaped insert rods 14 on both sides of the female mold plate 12 move downward, the arc-shaped ejector rod 4 rotates circumferentially, thereby driving the T-shaped frame 3 and the lower ejector plate 22 to move downward, causing the ejector pin body 27 to move downward. Even if jamming occurs under the action of the lower pressure frame 16, the connecting rod 24 moves downward, which in turn drives the upper ejector plate 23 to move downward.

[0030] Step 2: After the mold is opened to the correct position, the power unit pushes the lower ejector plate 22 and the upper ejector plate 23 to move upward. The inner periphery of the lower ejector plate 22 and the upper ejector plate 23 slides along the slide rod 26. The top of the slide rod 26 is fixedly connected to the bottom of the male template 28, and the bottom is fixedly connected to the top of the lower fixed plate 21, providing stable guidance for the movement of the ejector plate.
