Description
Technical Field
[0001] The utility model relates to the technical field of core-pulling forming dies, in particular to a multi-purpose core-pulling forming dies. Background Art
[0002] Die casting is widely used in various fields such as automobile parts, aircraft parts, ship parts and home appliance parts. For die casting products with simpler structures, there are no side recesses or side holes on the products, and they can generally be formed by simple flat die casting molds. For die casting products with more complex structures, there are side recesses or side holes on the product surface. Generally, it is necessary to set up a core pulling mechanism to form the side recesses or side holes on the products to ensure that the die casting mold can be opened smoothly.
[0003] When the undercut or side hole of the product is outside the product, it can be formed by the traditional core-pulling mechanism. When the undercut or side hole of the product is inside the product, it cannot be formed by the traditional core-pulling mechanism. Generally, in this case, the undercut or side hole inside the product will be realized by machining after the die-casting product is formed.
[0004] When the prior art processes some slender products with relatively simple structures but deep inner cavities, the products after molding will be in full contact with the slender inner mold, which makes demoulding more troublesome. Utility Model Content
[0005] The utility model aims to provide a multi-purpose core-pulling forming mold to solve the problem in the above-mentioned background technology that when processing products with a deep inner cavity, the formed products will fully contact with the slender inner mold, which is troublesome during demoulding.
[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a multi-purpose core-pulling forming mold, comprising a front template, a wear-resistant block and a first guide column, a wear-resistant block is arranged on the right side of the front template, a first guide column is arranged below the wear-resistant block, a rear template is movably installed on the right side of the front template, a square iron is fixedly installed on the upper right side of the rear template, a fixed plate is fixedly installed on the right side of the square iron, a ejector rear plate is fixedly installed below the fixed plate, an ejector front plate is fixedly installed on the left side of the ejector rear plate, and an ejector body is fixedly installed on the left side of the ejector front plate.
[0007] Preferably, a cylinder fixing plate is movably installed below the rear template, and a cylinder is fixedly arranged below the cylinder fixing plate.
[0008] Preferably, a second guide column is fixedly provided on the right side below the front template, and core pullers are movably installed on the lower parts of the front template and the rear template.
[0009] Preferably, a rear mold core is fixedly disposed on the right side of the core pulling, and a front mold core is fixedly disposed on the left side of the core pulling.
[0010] Preferably, a product compartment is fixedly provided on the inner side of the rear mold core and the front mold core, and a movable sheet is movably installed on the upper side of the front template and the rear template.
[0011] Preferably, a positioning pin is movably mounted on the inner end of the movable sheet, and a mold inlet is provided above the rear template.
[0012] The multi-purpose core-pulling forming mold is a mold specially designed for some products that are slender, relatively simple in structure, but have a very deep inner cavity. The first guide column and the second guide column are used to separate the long core pull from the product under the opening and closing force of the machine itself, and then the long core pull is pulled out by the force of the oil cylinder to avoid the situation where the core pull cannot be demolded during the production process due to the core pull being too long and the tightening force being too large, thereby affecting the production. It can effectively implement automated production, reduce labor, and improve efficiency. The bracket products have a deep cavity, thin product wall thickness, long core pull, relatively simple structure, and relatively large product demolding resistance. Through technical improvements, the problem of core pull demolding is not smooth, and production efficiency is improved. By setting a movable sheet, a positioning pin and a mold inlet, the device can be used to insert the positioning pin into the fixed limit hole on the movable sheet to fix the front template and the rear template together, making the device more stable when in use. The device is poured through the mold inlet during pouring, which is more convenient when in use.
