Abstract
The invention discloses a product injection molding method and device. The method includes the steps that molds are designed according to a product, a loose core is manufactured according to the size and shape of an inverted product, mold processing is conducted according to the mold design, and a loose core hole matched with the loose core is formed in a mold core; the molds are closed to be assembled to a set of complete mold, an injection molding machine is used for injecting molten plastic into the mold core, and the product in the specific shape is formed after cooling and solidification; the loose core is pulled out, the mold is opened, and the product is ejected. By means of the technical scheme, the inverted product can be smoothly ejected out of the mold under the effect of the loose core, parting lines are not generated on the appearance surface of the product, grinding is omitted, the processing cost is saved, environment pollution is avoided, the product appearance quality is improved, and the overall vision and hand feel are good.
Description
technical field [0001] The invention relates to the field of industrial manufacturing, in particular to a product injection molding method and device. Background technique [0002] Mold injection molding is a mature molding technology, which is widely used in mobile phone electronics, automobiles, home appliances and other industries. The injection molding machine injects molten plastic into the cavity of the mold, and forms a product with a specific shape after cooling and solidification, and then ejects the product and the nozzle through the ejector mechanism. [0003] When there is an undercut between the product structure and the mold opening direction, a mold auxiliary structure "row position" is adopted to make the undercut part of the product structure move back after the position movement to ensure that the product can come out of the mold core smoothly. figure 1 is a product schematic diagram in the prior art, figure 2 It is the effect diagram of the product form...
