Detailed Description

The following are specific embodiments of the present invention and the accompanying drawings are used to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

As shown in fig. 1-4, the press forming mold of the present invention includes a lower mold sleeve 100, a lower mold core 110, a fixed mold sleeve 111, a mounting assembly 200, a setting head 210, a blocking ring 211, a pushing ring 220, a bottom ring 230, a penetrating strip 240 and a mold assembly 300.

The lower die sleeve 100 is detachably connected with a lower die core 110, a fixed die sleeve 111 is installed in the lower die core 110, an installation assembly 200 is installed in the lower die sleeve 100, a shaping head 210 is installed on the installation assembly 200, a stop ring 211 is arranged at the bottom end of the shaping head 210, the stop ring 211 is clamped in the installation assembly 200, the shaping head 210 is inserted in the fixed die sleeve 111, a push ring 220 is sleeved on the side surface of the shaping head 210, a bottom ring 230 is arranged in the installation assembly 200, the push ring 220 is connected with the bottom ring 230 through a plurality of penetrating strips 240, the penetrating strips 240 penetrate through the stop ring 211, a die assembly 300 is arranged on the lower die core 110, the die assembly 300 can move relative to the fixed die sleeve 111, an upper die sleeve 310 is sleeved on the side surface of the die assembly 300, a circular truncated cone 112 for installing the upper die sleeve 310 is arranged on the upper end surface of the lower die core 110, a convex ring 311 corresponding to the circular truncated cone 112 is arranged on the lower end surface of the upper die sleeve, the material is put into the fixed die sleeve 111, then the die assembly 300 is inserted into the fixed die sleeve 111 again, so the material can be pressed and molded at one time through the extrusion action of the fixed head 210, the push ring 220, the fixed die sleeve 111 and the die assembly 300, because the upper die sleeve 310 is fixedly sleeved on the die assembly 300, when the die assembly 300 descends, the upper die sleeve 310 descends, when the convex ring 311 of the upper die sleeve 310 is just sleeved on the side surface of the circular truncated cone 112, the lower end surface of the lower die sleeve 100 is abutted against the upper end surface of the lower die core 110, the die assembly 300 presses the material in place, then the die assembly 300 is lifted again, thereafter, the push ring 220 is lifted relative to the fixed die sleeve 111 to push the material out of the fixed die sleeve 111, thus the people can conveniently collect the successfully pressed product, and in the process, because the stop ring 211 is embedded in the installation assembly 200, the fixed die sleeve 111 stops the stop ring 211 from separating from the installation assembly 200, make and wear strip 240 and hinder ring 211 and stably move upwards to make and hinder ring 211 and be located installation component 200 all the time, further improved the stability of this mould to the material suppression.

The side at the design head is inwards sunken to form ring slot 212, at the in-process of suppression material, select under the condition of predetermineeing weight because of the weight of material, the diameter that installation component one end was kept away from to the design head is greater than the diameter of ring slot 212, when the material is by the compression moulding, through the effect of ring slot 212, make the side direct contact that enters into the material between design head and the cover of cover and design head can not be with the design head, thereby avoid material and design head side direct contact, thereby reduce the frictional force of material and design head side, so, make this compression moulding mould can be the product with the material suppression smoothly.

The mounting assembly 200 includes an upper movable sleeve 250, a lower movable sleeve 260 and a fixed sleeve 270 installed in the lower die sleeve 100, the bottom ring 230 can move relative to the upper movable sleeve 250 and the lower movable sleeve 260, and during the movement of the bottom ring 230, the bottom ring 230 is always located in the upper movable sleeve 250 or the lower movable sleeve 260, a push rod 271 for pushing the bottom ring 230 to move is movably inserted in the fixed sleeve 270, the push rod 271 is fixedly connected with the bottom ring 230, when the pressing die presses the material into a product, after the pressing die assembly 300 has been removed, one only needs to push the push rod 271 upwards, because the push rod 271 is fixedly connected with the bottom ring 230, the bottom ring 230 is fixedly connected with each penetrating bar 240, the push ring 220 is fixedly connected with each penetrating bar 240, so that when the bottom ring 230 moves upwards, the push ring 220 also moves relative to the fixed die sleeve 111, further, because each penetrating bar 240 movably penetrates through the blocking ring 211, the penetrating bars 240 can stably move relative to the blocking ring 211, the push ring 220 can push out the product stably.

In the process that the push rod 271 drives the bottom ring 230 to descend, because the inner diameter of the upper movable sleeve 250 is the same as that of the lower movable sleeve 260, the inner diameter of the lower movable sleeve 260 is larger than that of the fixed sleeve 270, and the diameter of the bottom ring 230 is larger than that of the fixed sleeve 270 and smaller than that of the lower movable sleeve 260, when the bottom ring 230 abuts against the fixed sleeve 270, the bottom ring 230, the penetrating strip 240 and the push ring 220 are reset to be completed, so that the bottom ring 230 is prevented from being separated from the interior of the lower movable sleeve 260.

One side of the upper movable sleeve 250, which is far away from the lower movable sleeve 260, is provided with a supporting block 280 for supporting the fixed die sleeve 111 and the lower die core 110, the resistance ring 211 is clamped in the supporting block 280, and each penetrating strip 240 movably penetrates through the supporting block 280.

The die assembly 300 comprises a fixed block 320, an upper die core 330 is arranged on the lower end surface of the fixed block 320, an insert pin 340 is arranged in the upper die core 330, the upper die core 330 can be inserted into a fixed die sleeve 111, and a bushing 350 for preventing the upper die core 330 from moving in a dislocation manner is clamped in the upper die sleeve 310.

The pressing plate 120 is sleeved on the side surface of the lower mold core 110, the pressing plate 120 is detachably connected with the lower mold sleeve 100, when the lower mold core 110 is installed, people need to fixedly sleeve the pressing plate 120 on the side surface of the lower mold core 110, and the lower mold core 110 can be stably installed on the lower mold sleeve 100 through the threaded connection between the pressing plate 120 and the lower mold sleeve 100.
