Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a reciprocating hydraulic cylinder mold mechanism. Background Technology

[0002] The reciprocating hydraulic cylinder mold mechanism is a type of mechanism used in mold design. It utilizes the reciprocating motion of the hydraulic cylinder to achieve certain functions of the mold. Traditional reciprocating sliders can also remove the negative angle part of the mold, but after long-term use, due to the influence of many factors such as temperature and carbon buildup, the mold may deform in some parts, making it impossible to accurately reset. Therefore, we need to propose the reciprocating hydraulic cylinder mold mechanism. Utility Model Content

[0003] The purpose of this utility model is to provide a reciprocating hydraulic cylinder mold mechanism to improve the problem that the slider cannot accurately return to the positioning, resulting in step differences and excessively thin products, and even the possibility of breaking the sand core, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A reciprocating hydraulic cylinder mold mechanism includes a lower mold. A first mounting groove is provided on one side surface of the lower mold. A hydraulic cylinder pushing mechanism is installed inside the first mounting groove to assist in the direct forming of product shapes that cannot be demolded in the same direction. A second mounting groove is provided on one side of the lower mold located at the first mounting groove. A slanted shovel mechanism is installed inside the second mounting groove to assist in the forming of circular shapes within the frame and to maintain a shape that is easy to process. A downward pressing slant block connected to the upper mold is provided on the slanted shovel mechanism.

[0006] Preferably, the hydraulic cylinder pushing mechanism includes a mounting base, one end of which is fixedly mounted to the inside of the first mounting groove by bolts, a fixing plate is fixedly mounted to the inside of one end of the mounting base by bolts, a hydraulic cylinder is fixedly mounted on one side of the fixing plate, a pushing column is fixedly connected to one end of the piston end of the hydraulic cylinder, a pushing block for pushing the product is connected to one end of the pushing column, and the outer wall of the pushing block is slidably connected to the inner wall of the mounting base.

[0007] Preferably, a connecting block is fixedly installed at one end of the push column, and the connecting block is bolted to one side of the push block.

[0008] Preferably, notches are provided on the upper part of the inner walls on both sides of one end of the mounting base, and first limiting plates are fixedly installed inside the two sets of notches by bolts. One side of the two sets of first limiting plates is slidably connected to the upper sides of the pushing block.

[0009] Preferably, the inclined shovel mechanism includes a fixed base, which is fixedly installed inside the second mounting groove by bolts. A sliding block is slidably installed inside the fixed base. A cylindrical push block is fixedly installed at one end of the sliding block, and a reset pull rod is connected to the other end of the sliding block.

[0010] Preferably, a support block is fixedly installed inside the fixed base, a spring is fixedly installed on one side of the support block, one end of the reset lever passes through the spring and the support block and is fixedly connected to one end of the sliding block, and an abutment block that abuts against the end of the spring is fixedly installed at one end of the reset lever.

[0011] Preferably, the top side of the sliding block has a ramp that is adapted to the downward pressing block and extends into the interior of the sliding block.

[0012] Preferably, the fixing base is fixedly installed with second limiting plates on both sides above the sliding block by bolts, and one end of the two sets of second limiting plates is bolted to the inner walls of the two sides of the second mounting groove respectively.

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

[0014] By designing a hydraulic cylinder-driven mechanism, a hydraulic cylinder pushes a push column, which in turn drives a connecting block and a push block, thus directly forming product shapes that cannot be demolded in the same direction. This allows for smooth demolding at the secondary corners, and the mold can be more accurately reset to its positioning position. In addition, the inclined shovel mechanism plays a crucial role. When the upper mold descends, it drives the lower pressure shovel to squeeze the sliding block. The sliding block drives the cylindrical push block to be pushed forward inside the second mounting groove, thus helping to form the circular shape inside the frame and maintain a shape that is easy to process. When the upper mold rises, the inclined shovel mechanism does not apply any other force; the spring pulls the sliding block back to its original position through the reset rod. This design effectively solves the problem of slider skewing caused by weight, wear and tear, and deformation of some large-area sliders. It avoids the impact of wear and tear on the final product's appearance after long-term use of the mold, thereby indirectly extending the mold's service life. Attached Figure Description

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-5 This utility model provides a technical solution:

[0023] The reciprocating hydraulic cylinder mold mechanism includes a lower mold 1. A first mounting groove 2 is provided on one side surface of the lower mold 1. A hydraulic cylinder pushing mechanism 3 is installed inside the first mounting groove 2 to assist in the direct forming of product shapes that cannot be demolded in the same direction. A second mounting groove 4 is provided on one side of the lower mold 1 located in the first mounting groove 2. A slanted shovel mechanism 5 is installed inside the second mounting groove 4 to assist in the forming of circular shapes in the frame and to maintain a shape that is easy to process. A downward pressing slant block 6 connected to the upper mold is provided on the slanted shovel mechanism 5.

[0024] Furthermore, the hydraulic cylinder pushing mechanism 3 includes a mounting base 31. One end of the mounting base 31 is fixedly installed inside the first mounting groove 2 by bolts. A fixing plate 32 is fixedly installed inside the mounting base 31 by bolts. A hydraulic cylinder 33 is fixedly installed on one side of the fixing plate 32. A pushing column 34 is fixedly connected to one end of the piston end of the hydraulic cylinder 33. A pushing block 36 for pushing the product is connected to one end of the pushing column 34. The outer wall of the pushing block 36 is slidably connected to the inner wall of the mounting base 31. The hydraulic cylinder 33 pushes the pushing column 34, and the pushing column 34 then drives the pushing block 36 to extend into the first mounting groove 2, thereby directly forming the shape of products that cannot be demolded in the forward direction, so that the secondary corners can be demolded smoothly and the mold can be more accurately reset to the positioning position.

[0025] Specifically, a connecting block 35 is fixedly installed at one end of the push column 34. The connecting block 35 is bolted to one side of the push block 36, so that the push column 34 and the push block 36 can be connected and installed through the connecting block 35.

[0026] Specifically, notches 38 are provided on the upper part of the inner walls on both sides of one end of the mounting base 31. The first limiting plate 37 is fixedly installed inside the two sets of notches 38 by bolts. One side of the two sets of first limiting plates 37 is slidably connected to the upper sides of the push block 36, so as to limit the sliding of the push block 36 by the two sets of first limiting plates 37, thereby improving the moving accuracy and stability of the push block 36.

[0027] Furthermore, the slanted shovel mechanism 5 includes a fixed base 51, which is fixedly installed inside the second mounting groove 4 by bolts. A sliding block 52 is slidably installed inside the fixed base 51. A cylindrical push block 53 is fixedly installed at one end of the sliding block 52, and a reset pull rod 57 is connected to the other end of the sliding block 52. This facilitates the movement of the sliding block 52 to push the cylindrical push block 53 towards the front inside the second mounting groove 4, thereby helping to form a circular shape inside the frame and maintain a shape that is easy to process.

[0028] Specifically, a support block 55 is fixedly installed inside the fixed base 51, and a spring 56 is fixedly installed on one side of the support block 55. One end of the reset rod 57 passes through the spring 56 and the support block 55 and is fixedly connected to one end of the sliding block 52. An abutment block that abuts against the end of the spring 56 is fixedly installed at one end of the reset rod 57, so that the spring 56 can pull the sliding block 52 back to its original position through the reset rod 57.

[0029] Specifically, a ramp is provided on one side of the top of the sliding block 52, which is adapted to the downward pressing block 6 and extends into the interior of the sliding block 52 (the downward pressing block 6 is installed on the upper mold, which is not shown in the upper mold figure). This is so that when the upper mold descends, it will drive the downward pressing block 6 to squeeze the sliding block 52, and the sliding block 52 will drive the cylindrical push block 53 to be pushed forward into the second mounting groove 4.

[0030] Specifically, the fixed base 51 is located on both sides above the sliding block 52 and is fixed with second limiting plates 54 by bolts. One end of the two sets of second limiting plates 54 is bolted to the inner walls of the two sides of the second mounting groove 4, so that the two sets of second limiting plates 54 can limit and guide the sliding block 52.

[0031] Working Principle: This invention utilizes a hydraulic cylinder pushing mechanism 3. The hydraulic cylinder 33 pushes the pushing column 34, which in turn drives the connecting block 35 and the pushing block 36, directly forming product shapes that cannot be demolded in the same direction. This allows for smooth demolding at the secondary corners and more precise mold repositioning. Furthermore, the inclined shovel mechanism 5 plays a crucial role. When the upper mold descends, it drives the downward pressing block 6 to squeeze the sliding block 52. The sliding block 52 then pushes the cylindrical push block 53 towards the front of the second mounting groove 4, helping to form the circular shape within the frame and maintaining a shape suitable for processing. When the upper mold rises, the inclined shovel mechanism 5 does not apply any other force; the spring 56 pulls the sliding block 52 back to its original position via the reset rod 57. This design effectively solves the problem of slider skewing caused by weight, wear and tear, and deformation of larger sliders. It avoids the impact of mold wear and deformation on the final product's appearance after prolonged use, thus indirectly extending the mold's service life.
