TECHNICAL FIELD
[0001] The utility model relates to injection molding machine mould structure technical field, concretely is a perfume shoulder sleeve strong demould structure of front mould core pulling first. BACKGROUND
[0002] There are many kinds of products produced by injection molding, and part of the products are products with strong demolding structure, for example, the perfume shoulder sleeve product used on the perfume bottle, the front mould part of the product has a ring protruding buckle position, if the normal mould structure needs to be made into a slide outside, it will not only increase the mould cost, but also have a mould line on the product outside, which affects the appearance of the product. UTILITY MODEL CONTENTS
[0003] The utility model discloses to the injection molding product demolding problem with the protruding buckle position of the external demolding surface, and a perfume shoulder sleeve strong demould structure of front mould core pulling first is provided, a core pulling strong demolding structure is designed, and when the front mould buckle strong demolding is adopted, the structure of first abstracting the internal insert and leaving the position makes that product plastic deformation and strong demolding deformation realize the buckle demolding.
[0004] Therefore, the utility model provides the following technical scheme:
[0005] A perfume shoulder sleeve strong demould structure of front mould core pulling first, including front mould component, rear mould component, front mould component, rear mould component together injection molding production perfume shoulder sleeve, the top sleeve mouth outside of perfume shoulder sleeve is equipped with the annular buckle that protrudes outward, the front mould component includes front mould kernel, front mould plate, annular spring rubber, drop-off board, faceplate, sprue sleeve, first core pulling insert, the rear mould component includes rear mould kernel, rear mould plate, the bottom of the front mould plate is fixedly connected with the front mould kernel, the top of the front mould plate is equipped with annular groove, the annular spring rubber is equipped in annular groove, the drop-off board is equipped at the top of front mould plate, the faceplate is equipped at the top of drop-off board, the tail end of sprue sleeve is fixed with faceplate, the first end of sprue sleeve passes through faceplate, drop-off board and first core pulling insert tail end connection, the first end of first core pulling insert passes through front mould plate, front mould kernel, the front mould kernel is tightly attached with rear mould kernel and forms product cavity, the middle part outside of first core pulling insert is equipped with annular fender ring, the middle part of front mould plate is equipped with the lifting groove that cooperates with annular fender ring, the bottom of rear mould kernel is fixedly connected with rear mould plate.
[0006] The product of the perfume shoulder sleeve is aimed at, the buckle position of the product front mold part has a circle protrusion, if the normal mold structure needs to be made outside the slider, which not only increases the mold cost, but also has the mold line outside the product, which affects the product appearance, therefore, the scheme designs the first core pulling strong stripping structure to realize the product ejection structure, to realize the front mold buckle strong stripping, the internal insert must be first pulled away to leave the position, the product plastic deformation and strong deformation realize the buckle demolding, when the mold is opened, the rear mold assembly moves backward, under the action of the spring rubber between the stripping plate and the front mold plate, the two plates will first separate, but the connection between the sprue sleeve and the first core pulling insert is unchanged, that is, the driving buckle at the sprue sleeve keeps the gate unchanged, the insert driving connection buckle will pull the first core pulling insert to keep it unchanged, at this time, the front mold plate, front mold core and the like move away from the rear mold direction, so that the first core pulling insert is separated from the product, leaving the product deformation space, finally, the product buckle is separated from the front mold core, and the product can be taken out.
[0007] As a preferred scheme of the utility model, the product cavity injection forms the perfume shoulder sleeve, the top sleeve of the perfume shoulder sleeve is a hollow tubular, and the bottom of the sleeve is provided with a conical ring table.
