Description

Technical Field

[0001] This utility model relates to the field of pressing molds, specifically a four-sided split-opening pressing mold. Background Technology

[0002] Mold pressing is a method of forming a blank with a certain shape and size by using pressure to compress powder placed in a mold into a dense structure.

[0003] Traditional pressing molds are installed on unidirectional pressing equipment and can only perform unidirectional pressing. When pressing irregularly shaped products, due to the limitation of the pressing direction, it is impossible to actively optimize the material distribution according to the product shape, resulting in serious density unevenness in the product. When the product size is small, the opening of the traditional mold is too small to directly fill the material, and a pre-forming process must be added before the material can be filled and pressed smoothly. Utility Model Content

[0004] The purpose of this invention is to provide a four-sided split-opening pressing mold to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a four-sided split-opening pressing mold, comprising:

[0006] The upper mold has an upper pressure head inside.

[0007] The lower mold has a pair of pressure heads inside, the bottom of the upper mold has a guide post and an upper pressure plate, and the top of the lower mold has a first slider and a second slider.

[0008] Preferably, the top of the upper mold is provided with a lifting mechanism, which drives the upper mold to move up and down. The upper pressure plate is fixed to the bottom of the upper mold, and the guide post is inserted into the inside of the upper pressure plate. The guide post can extend and retract inside the upper pressure plate.

[0009] Preferably, the upper pressure plate is provided with a telescopic drive device inside, which can drive the guide column to telescopically move.

[0010] Preferably, the surface of the lower mold is fixed with four sets of inclined guide pillars, the inclined guide pillars are inclined, and two sets of first sliders and two sets of second sliders are sleeved on the outside of the inclined guide pillars.

[0011] Preferably, the first and second sliders can move along the inclined guide post, and a filling groove is provided on the surface of the lower mold, which is located at the middle position of the first and second sliders.

[0012] Preferably, the bottom of the lower mold is fixed to the base, and the raw material is placed in the filling groove.

[0013] Compared with the prior art, the beneficial effects of this utility model are:

[0014] The first slider proposed in this utility model moves downward along the inclined guide post. Since the inclined guide post is inclined, the two sets of first sliders move closer to each other and squeeze the raw material from the side. After the guide post is retracted into the interior of the upper mold, the upper mold continues to descend, so that the upper pressure plate presses against the surface of the second slider. The two sets of second sliders move closer to each other and squeeze the other two sides of the raw material. After the upper mold continues to descend, the upper pressure head at the bottom of the upper mold and the lower pressure head at the top of the lower mold can squeeze the top and bottom of the raw material, so that all surfaces of the raw material are squeezed. Since the first slider and the second slider are movable, it is convenient to place the raw material. Attached Figure Description

[0019] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0020] Please see Figures 1-3 This utility model provides a technical solution: a four-sided split-opening pressing mold, including: an upper mold 11, an upper pressure head 1 inside the upper mold 11, a lifting mechanism on the top of the upper mold 11, the lifting mechanism driving the upper mold 11 to rise and fall, an upper pressure plate 4 fixed to the bottom of the upper mold 11, after the upper mold 11 continues to descend, the raw material can be squeezed at the top and bottom through the upper pressure head 1 at the bottom of the upper mold 11 and the lower pressure head 2 at the top of the lower mold 10, a guide post 3 inserted into the interior of the upper pressure plate 4, the guide post 3 can move telescopically inside the upper pressure plate 4, and a telescopic drive device is provided inside the upper pressure plate 4, the telescopic drive device can drive the guide post 3 to move telescopically.

[0021] The lower mold 10 has a pressure head 2 inside. The bottom of the upper mold 11 has a guide post 3 and an upper pressure plate 4. The top of the lower mold 10 has a first slider 7 and a second slider 8. Four sets of inclined guide posts 9 are fixed on the surface of the lower mold 10. The inclined guide posts 9 are inclined. Two sets of first sliders 7 and two sets of second sliders 8 are sleeved on the outside of the inclined guide posts 9. The first sliders 7 and the second sliders 8 can move along the inclined guide posts 9. The surface of the lower mold 10 has a filling groove 6. The filling groove 6 is located in the middle of the first sliders 7 and the second sliders 8. The bottom of the lower mold 10 is fixed on the base. Raw materials are placed in the filling groove 6. The first sliders 7 move down along the inclined guide posts 9. Because the inclined guide posts 9 are inclined, the two sets of first sliders 7 move closer to each other and squeeze the raw materials from the side.

[0022] In actual use, the raw material is placed in the filling groove 6. As the upper mold 11 moves down, the pilot post 3 at the bottom of the upper mold 11 first contacts the first slider 7 on the surface of the lower mold 10, causing the first slider 7 to move down along the inclined guide post 9. Since the inclined guide post 9 is inclined, the two sets of first sliders 7 move closer to each other, squeezing the raw material from the side. After the pilot post 3 is retracted into the interior of the upper mold 11, the upper mold 11 continues to descend, causing the upper pressure plate 4 to press against the surface of the second slider 8. The two sets of second sliders 8 move closer to each other, squeezing the other two sides of the raw material. After the upper mold 11 continues to descend, the upper pressure head 1 at the bottom of the upper mold 11 and the lower pressure head 2 at the top of the lower mold 10 can squeeze the raw material from the top and bottom, so that all sides of the raw material are squeezed. Since the first slider 7 and the second slider 8 are movable, it is convenient to place the raw material.

[0023] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
