Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 to 6, the embodiment of the application provides a router is mould for upper cover, including last mould 1 and lower mould 2, the relative position of going up mould 1 and lower mould 2 cladding respectively is provided with mould benevolence 3 and lower mould benevolence 4, the relative position of going up mould benevolence 3 and lower mould benevolence 4 is provided with die cavity and lower die cavity respectively, be provided with the spout respectively, four along being provided with respectively around the lower die cavity on the lower mould 2 equal sliding connection has side to take out slider 5 in the spout, be provided with on the lower mould 2 and be used for driving the gliding drive assembly of side take out slider 5, be close to one side fixedly connected with shaping auxiliary block 6 of lower die cavity on the slider 5 is taken out to the side, it is formed with the fashioned die cavity that is used for the product to go up between die cavity, shaping auxiliary block 6 and the lower die cavity. One of the auxiliary molding blocks 6 is provided with a glue inlet flow channel 61 and a longitudinal sliding groove which are mutually communicated, the glue inlet flow channel 61 is communicated with the cavity, the upper mold 1 is provided with a pouring opening 7 communicated with the glue inlet flow channel 61, the longitudinal sliding groove is internally provided with a degumming thimble 8, the lower mold 2 is provided with a cavity 231 for the degumming thimble 8 to transversely slide, and the cavity 231 is internally provided with a movable ejector rod 10 which is abutted against the degumming thimble 8 and can drive the degumming thimble 8 to lift. And the lower die 2 is provided with a thimble hole communicated with the die cavity, and a stripping thimble is slidably connected in the thimble hole.

During injection molding, the degumming thimble 8 is accommodated in the longitudinal sliding groove to plug the longitudinal sliding groove, raw materials enter the glue inlet flow passage 61 along the pouring opening 7, and finally the raw materials are injected into the cavity to realize product molding. During demoulding, the upper mould 1 is separated from the lower mould 2, the driving component drives the side drawing slide block 5 to slide towards the periphery of the lower mould 2, so that the auxiliary forming block 6 is separated from a product, meanwhile, the degumming thimble 8 can slide along with the auxiliary forming block 6, so that the degumming thimble 8 cannot interfere with the sliding of the auxiliary forming block 6, then, the material stripping thimble ejects the product out of the lower mould cavity, the movable ejector rod 10 rises to eject the residual glue in the glue inlet flow channel 61, and it needs to be noted that the material stripping thimble and the movable ejector rod 10 are driven by an external power device.

In the above mode, through the setting of four side extraction sliders 5, during the drawing of patterns, can make things convenient for the supplementary piece of shaping 6 and the barb on product and the product to harmless the separation fast, be difficult to damage the product, effectively improve the yields of product to with the setting of injecting glue runner on side extraction slider 5, the raw materials is from one side injection moulding product of die cavity, make the surface of product can not leave the injecting glue seal of a government organization in old china, can satisfy the requirement of product aesthetic property.

On the basis, the driving assembly comprises an inclined guide post fixedly connected to the upper die 1 through a connecting block, an inclined guide groove matched with the inclined guide post is formed in the side pulling sliding block 5, and one end, far away from the upper die 1, of the inclined guide post is connected to the inclined guide groove in a sliding mode.

When the lateral drawing sliding block works, the oblique guide post only longitudinally rises, and the lateral drawing sliding block 5 only transversely slides, so that the oblique guide post gives an outward transverse thrust to the lateral drawing sliding block 5 when rising, and the lateral drawing sliding block 5 outwards slides.

In the mode, the four sliding blocks can slide outwards in a linkage manner through demoulding of the upper die 1 and the lower die 2, an additional driving device is not needed, and the four-sliding-block demoulding mechanism has the advantages of simple structure and low design and manufacturing cost.

On the basis, a limiting part is arranged on the degumming thimble 8, and a spring 9 is sleeved between the limiting part and the side-pulling slide block 5 on the degumming thimble 8.

When the degumming device works, the spring 9 applies downward pulling force to the degumming thimble 8, and the degumming thimble 8 is tightly propped against the movable ejector rod 10.

In the manner, in the injection molding process, the degumming thimble 8 cannot slide upwards into the glue inlet flow channel 61 due to looseness, so that the injection molding raw material flows more smoothly.

On the basis, the upper die 1 comprises an upper bottom plate 11, a fixing plate 12 fixed on the upper bottom plate 11 and an upper die frame 13 fixed on the fixing plate 12, and the lower die 2 comprises a lower bottom plate 21, a lower die frame 23 and a square iron 22 arranged between the lower bottom plate 21 and the lower die frame 23.

Specifically, the upper base plate 11, the fixing plate 12 and the upper mold frame 13 are fixedly connected through bolts, and a buffer is further arranged between the lower mold frame 23 and the lower fixing plate 12.

In this way, when the upper mold 1 and the lower mold 2 are closed, the square iron 22 can disperse the stress between the lower mold frame 23 and the lower base plate 21, so that the molds are not easily damaged.

On the basis, one end of the degumming thimble 8 close to the movable ejector rod 10 is spherical.

Specifically, the contact end of the degumming thimble 8 and the movable ejector rod 10 is set to be spherical, so that the contact of the degumming thimble 8 and the movable ejector rod 10 is point contact.

In such a way, the friction force between the degumming thimble 8 and the movable ejector rod 10 is reduced, so that the degumming thimble 8 can slide along with the forming auxiliary block 6 more smoothly.

It is above only the utility model discloses a preferred embodiment, the utility model discloses a scope of protection does not only confine above-mentioned embodiment, the all belongs to the utility model discloses a technical scheme under the thinking all belongs to the utility model discloses a scope of protection. It should be noted that, for those skilled in the art, various modifications and decorations can be made without departing from the principle of the present invention, and these modifications and decorations should also be regarded as the protection scope of the present invention.
