Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of injection molds, in particular to a novel slider mechanism. Background Art
[0002] Generally, in traditional products of this kind, it is generally difficult to keep the slider on the core-pulling rotating plate closed in the first shot to fix the product on the core-pulling rotating plate and open it in the second shot to take out the product, resulting in defective products or sticking to the front / rear molds, and the large structural size affects the overall design of the mold.
[0003] Therefore, there is a need for a mechanism that keeps the slider closed in the first shot and opens in the second shot during two-color core-pulling and ejection, which greatly improves the production of multi-color molds, reduces the processing cost and labor cost of the molds, and also greatly shortens the molding cycle of the products and improves the overall quality of the products. Summary of the Utility Model
[0004] Purpose of the Utility Model: The purpose of the utility model is to provide a mechanism that keeps the slider closed in the first shot and opens in the second shot during two-color core-pulling and ejection; another purpose of the utility model is to provide a mechanism that reduces the processing cost and labor cost of the molds, and also greatly shortens the molding cycle of the products and improves the overall quality of the products.
[0005] Technical Solution: A novel slider mechanism includes a core-pulling rotating plate, a slider insert is fixedly connected above the core-pulling rotating plate, a spring block is fixedly connected to the outer side wall of the slider insert, and a spring bow is arranged on the outer side wall of the spring block.
[0006] Furthermore, a pressing plate is fixedly connected to the outer side wall of the slider insert, and a baffle is fixedly connected to the front surface of the slider insert.
[0007] Furthermore, a positioning pin is arranged inside the slider insert.
[0008] Furthermore, first-shot ejector dogs are symmetrically and fixedly connected to the left side of the upper surface of the core-pulling rotating plate.
[0009] Furthermore, second-shot ejector dogs are symmetrically and fixedly connected to the right side of the upper surface of the core-pulling rotating plate.
[0010] Furthermore, the spring bow and the spring block form a locking dog device.
[0011] Beneficial Effects: Aiming at the shortcomings of the prior art, this project provides a more concise structural design of the slider on the core-pulling rotating plate that remains closed in the first shot and opens in the second shot, enabling the mold to achieve full-automatic production, shortening the product molding cycle, reducing the labor cost, making the product appearance more perfect, and breaking the trouble of semi-automatic production of traditional molds of this kind.
[0012] When both the product and the slider are located on the core-pushing rotating plate, while minimizing the size of the slider to the greatest extent, it is ensured that the slider does not open in the first shot to fix the product, and opens in the second shot to take out the product. This new technology is simple and delicate in structure, solving the problem that when both the product and the slider are located on the core-pushing rotating plate, the core-pushing rotating plate is too large and heavy, and it is difficult to ensure the precise positioning of the product in the first shot when the second shot is closed. It provides driving force for the technical field of the mold industry. Brief Description of the Drawings

[0017] To make the technical solution of the present utility model clearer, the following further describes the present utility model in detail with reference to the accompanying drawings and specific embodiments.
[0018] Embodiment 1
[0019] As Figures 1-3 shown, a new type of slider mechanism is provided, including a core-pushing rotating plate 9. A slider insert 1 is fixedly connected above the core-pushing rotating plate 9. A spring block 2 is fixedly connected to the outer side wall of the slider insert 1. A spring 5 is arranged on the outer side wall of the spring block 2. A pressure plate 3 is fixedly connected to the outer side wall of the slider insert 1. A baffle 4 is fixedly connected to the front surface of the slider insert 1. A positioning pin 6 is arranged inside the slider insert 1. First-shot ejectors 7 are symmetrically and fixedly connected to the left side of the upper surface of the core-pushing rotating plate 9, and second-shot ejectors 8 are symmetrically and fixedly connected to the right side of the upper surface of the core-pushing rotating plate 9. The spring 5 and the spring block 2 form a locking device;
[0020] The spring 5 and the spring block 2 form a locking device to transmit power for the opening of the slider insert 1; the pressure plate 3 and the fixed pin 6 are installed on the slider insert to limit the stroke and position of the spring block 2. The baffle 4 is on the core-pushing rotating plate 9 to limit the position of the slider insert 1. The slider insert 1 is installed on the core-pushing rotating plate 9 to control the product forming and the positioning of the product when the core-pushing rotating plate 9 ejects and rotates. The first-shot ejectors 7 and the second-shot ejectors 8 are installed on the front mold body to provide power for controlling the position and state of the slider insert during mold opening and closing;
[0021] After the first shot of injection molding and mold opening, there is no locking position on the first-shot lifter block 7, and it does not contact the slingshot 5 and the ejector block 2, so no force for movement is provided. The first-shot insert 1 does not move. The injection molding machine connects the ejector rod to eject the core rotating plate 9, and the core rotating plate 9 moves upward by 100 mm. The product is fixed on the core rotating plate 9 by the lifter in the pressing plate 3 and the baffle 4 and moves together. The oil cylinder drives the rack and gear to move, and the core rotating plate 9 rotates 180°. The product on it rotates 180° together with the lifter. Then the ejector rod pulls back, and the mold closes. At this time, there is no product in the first-shot cavity, and there is only the first-shot product in the second-shot cavity. The lifter components on the core rotating plate also adjust their positions accordingly. After the second shot of injection molding and mold opening, the second-shot lifter block 8 is locked by the slingshot 5 and the ejector block 2 to drive the insert 1 to move out of the product. The ejector rod ejects, and the product and the lifter move with the core rotating plate 9 under the action of the pressing plate 3 and the baffle 4 respectively. The robot smoothly takes out the product, and the core mounting plate 9 rotates 180° to close the mold. The first-shot lifter block 7 presses the insert 1 back to its original position.
[0022] The above embodiments only illustrate several implementation manners of the present utility model, and the description is relatively specific and detailed. However, it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model. Therefore, the protection scope of the patent of the present utility model shall be subject to the appended claims.
