Description

Injection mold easy to open and eject

Technical Field

The utility model relates to an injection mold technical field specifically is an easy ejecting injection mold of die sinking.

Background

An injection mold is a tool for producing plastic products, and a material melted by heat is injected into a mold cavity from high pressure, and a formed product is obtained after cooling and solidification. Because the structures of most existing injection molding products are very complex, in the actual die opening process, various ejection mechanisms are often needed to eject the injection molding products, however, most of the ejection mechanisms adopt the ejection mechanisms to directly eject finished products, so that the products are easily damaged, and the yield is reduced.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide an easy ejecting injection mold of die sinking to solve the problem of proposing in the above-mentioned background art.

In order to achieve the above object, the utility model provides a following technical scheme: an injection mold easy to open and eject comprises a bottom plate, wherein lower mold plates are arranged on the left side and the right side of the upper surface of the bottom plate through pillars, lower mold cores are arranged in the lower mold plates, an upper mold plate matched with the lower mold plates is mounted at the upper ends of the lower mold plates, upper mold cores matched with the lower mold cores are arranged at the lower ends of the upper mold plates, and ejection structures are arranged on the bottom plate;

the ejection structure comprises a cylinder installed on the upper surface of the bottom plate, the cylinder driving end is vertically upward, a mounting plate is installed on the cylinder driving end, ejector rods are installed on the left side and the right side of the upper wall surface of the mounting plate, sleeves are sleeved on the ejector rods in a vertically sliding mode, springs are installed on the inner upper wall surface of each sleeve, the lower ends of the springs are connected with the upper ends of the ejector rods respectively, the sleeves extend upwards to penetrate through the lower die plate and the lower die core, and the sleeves are connected with the lower die plate and the lower die core in a vertically.

Compared with the prior art, the beneficial effects of the utility model are that: this easy ejecting injection mold of die sinking is rational in infrastructure, and the design is simple, and is ejecting gradually the finished product through ejecting structure, the utility model discloses an ejecting process relaxes, and not fragile product has effectually improved the success rate of processing.

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.

Referring to fig. 1, the present invention provides a technical solution: an injection mold easy to open and eject comprises a bottom plate 1, wherein lower templates 3 are arranged on the left side and the right side of the upper surface of the bottom plate 1 through pillars 2, lower mold cores 4 are arranged in the lower templates 3, an upper template 5 matched with the lower templates 3 is installed at the upper end of the lower templates 3, an upper mold core 6 matched with the lower mold core 4 is arranged at the lower end of the upper template 5, and an ejection structure 7 is arranged on the bottom plate 1;

ejecting structure 7 is including installing cylinder 71 in bottom plate 1 upper surface, cylinder 71 drive end is vertical upwards, and cylinder 71 drive end is equipped with mounting panel 72 on, the wall left and right sides is equipped with ejector pin 73 on mounting panel 72, all slide the cover from top to bottom on ejector pin 73 and be equipped with sleeve pipe 74, the wall is equipped with spring 75 on the interior wall of sleeve pipe 74, spring 75 lower extreme is connected with ejector pin 73 upper end respectively, sleeve pipe 74 upwards extends and runs through lower bolster 3 and lower mold core 4, slide connection from top to bottom between sleeve pipe 74 and lower bolster 3 and the lower mold core 4.

Preferably, the outer upper wall surface of the sleeve 74 is provided with a protective pad 8.

Preferably, the reinforcing rods 9 are welded to the left and right sides of the driving end of the air cylinder 71, and the reinforcing rods 9 are welded to the left and right sides of the lower wall surface of the mounting plate 72 away from the driving end of the air cylinder 71.

Preferably, the protection pad 8 is made of rubber.

When the device is used, the cylinder 71 is started, the driving end of the cylinder 71 does reciprocating motion in the vertical direction, the mounting plate 72 is driven to move up and down through the reciprocating motion of the driving end of the cylinder 71, so that the sleeve 74 is driven to move up and down, a finished product is ejected gradually through the up and down movement of the sleeve 74, the friction between the finished product and the mold is reduced along with the ejection of the finished product because the contact area between the finished product and the mold is large and the friction force is large before the finished product is ejected, when the finished product is ejected gradually, the highest positions of the sleeve 74 are increased under the action of the spring 75, the finished product can be ejected conveniently along with the gradual increase of the highest positions of the sleeve 74, so that the product is gradually peeled from the cavity, the ejection process is mild under the action of the spring 75, the product is not easy to damage, the success rate of, the connection between the mounting plate 72 and the cylinder 71 can be reinforced by the reinforcing rod 9.
