Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold core pulling, and more specifically to a novel cylinder with an inclined core pulling structure. Background Art
[0002] The injection mold consists of an upper mold and a lower mold. During injection molding, the upper mold and the lower mold are closed to form a pouring system and a cavity. When the mold is opened, the upper mold and the lower mold are separated, and the plastic product in the cavity is ejected using an ejector pin to complete the injection molding. The core pulling structure is a design used to create protrusions or cavity parts in the mold. It mainly embeds movable core pulling components into the mold so that these parts can be pushed out or retracted from the mold during the molding process. The core pulling structure plays a key role in mold design. It enables products with complex shapes to be produced smoothly and can improve production efficiency and product quality.
[0003] However, for a specific mold with a small-angle long hole in the mold product, a long oblique core pulling is required, which cannot be achieved with the traditional ejector plate. Therefore, it is necessary to use the cylinder to drive the oblique core pulling needle to perform long-distance oblique core pulling. To this end, we propose a new cylinder with oblique core pulling structure to solve the above problem. Utility Model Content

[0020] In the embodiment of the present application, when in use, the device is first installed inside the mold. When working, it sets an oblique retreat seat 4 on the mold core, and drives the oblique retreat seat 4 to move horizontally by starting the cylinder 1. When the oblique retreat seat 4 moves horizontally, it can push the mold core to move along the rib extension direction, thereby realizing the oblique core pulling movement during demoulding. Before opening the mold, the cylinder 1 starts to shrink, the Ab plate opens the mold, and the slider retreats. Due to the retreat of the slider, the limit of the oblique retreat rod 5 is cancelled, and the cylinder 1 pulls the core backward, driving the oblique retreat seat 4 to make the oblique retreat rod 5 perform an oblique retreat action. After the oblique retreat is completed, the ejector rod ejects the ejector plate, which facilitates the sequential mold opening and closing operations and extends the service life of the mold.
[0021] Furthermore, the water transfer assembly 6 includes a water transfer rod 63 inserted on one side of the top of the cylinder fixing block 2. The water transfer rod 63 extends through the cylinder fixing block 2 to one end of the bottom and is fixedly connected to a water transfer connecting block 61. One side of the water transfer connecting block 61 is fixedly connected to a water nozzle 62. The water nozzle 62 is connected to the water transfer rod 63 through the water transfer connecting block 61. There are two water nozzles 62, which are symmetrically distributed along the upper and lower outer walls of the water transfer connecting block 61. When in use, the setting of the water transfer rod 63 makes it convenient to set a flow channel according to the requirements of the product structure to guide the molten metal into the mold cavity for molding. The water transfer rod 63 can be used to control the transfer of the flow channel, so that the molten metal can be smoothly transferred from one flow channel to another, thereby ensuring the molding quality of the product.
[0022] Furthermore, an inclined slide groove is provided on the top of the oblique retreat seat 4, and is compatible with the oblique retreat rod 5. The oblique retreat rod 5 and the water transfer assembly 6 are both obliquely arranged. When in use, the oblique retreat rod 5 is inclined to allow the oblique retreat rod 5 to slide stably on the oblique retreat seat 4, which is convenient for long-distance oblique core pulling operations. The structure is simple and the stability is strong.
[0023] The working principle of the utility model is as follows: when in use, the device is first installed inside the mold. When working, an oblique retreat seat 4 is set on the mold core, and the oblique retreat seat 4 is driven to move horizontally by starting the cylinder 1. When the oblique retreat seat 4 moves horizontally, the mold core can be pushed to move along the rib extension direction, thereby realizing the oblique core pulling movement during demoulding. Before opening the mold, the cylinder 1 starts to shrink, the Ab plate opens the mold, and the slider retreats. Due to the retreat of the slider, the limit of the oblique retreat insert rod 5 is cancelled, and the cylinder 1 pulls the core backward, driving the oblique retreat seat 4 to make the oblique retreat insert rod 5 perform an oblique retreat action. After the oblique retreat is completed, the ejector rod ejects the ejector plate, which facilitates the sequential mold opening and closing operations and extends the service life of the mold.
