Description

Technical Field

[0001] The utility model relates to the technical field of casting demoulding, in particular to an auxiliary demoulding tool. Background Art

[0002] In the process of casting production, it is necessary to use a die tool to apply pressure with the assistance of a hydraulic press, and vigorously knock the die tool into the inside of the casting to form a set shape on the casting. Commonly used die tools are made of metal and non-metal materials, including metal blocks and wooden blocks. Especially in the process of processing long grooves on the surface of the product, in order to prevent excessive stress, the die tool will be divided into multiple small pieces. After pressing, a demolding tool is needed to remove the die tool embedded in the product. There are many kinds of existing mold removal tools, but most of them use a pry bar or a grab bar to pry the die tool from the side to remove it. Because some of them are embedded more tightly, it is not very convenient to operate. Sometimes the product will be damaged during the prying process, resulting in defective products and affecting production. Utility Model Content

[0003] The utility model aims to overcome the disadvantage of the prior art that there is great inconvenience in taking out the die tool, and provides an auxiliary demoulding tool.

[0004] In order to achieve the above-mentioned purpose, the embodiment of the utility model specifically adopts the following technical scheme: an auxiliary demoulding tool, including an operating rod, a bottom block is arranged at the bottom of the operating rod, a connecting hole is arranged in the middle position of the bottom block, a connecting head connected to the mold is detachably arranged inside the connecting hole, a sliding sleeve that slides up and down is sleeved on the rod body of the operating rod, and an inertia block for increasing weight is arranged on the top of the sliding sleeve.

[0005] Furthermore, a curved portion for hand grip is provided on the top of the operating rod, and the curved portion is bent toward the side of the operating rod.

[0006] Furthermore, a pull rod is transversely arranged on the side wall of the sliding sleeve, and a handle is arranged at the end of the pull rod.

[0007] Furthermore, an impact block is provided on the upper portion of the operating rod, and the impact block is arranged above the inertia block.

[0008] Furthermore, a toothed rubber ring is arranged inside the sliding sleeve, and the toothed portion of the rubber ring abuts against the side surface of the operating rod.

[0009] Furthermore, the side edges of the bottom surface of the bottom block are arranged in an arc shape, and a connecting ring for fixing a connecting rope is arranged on the top surface of the bottom block.

[0010] The beneficial effects of the embodiments of the utility model are as follows: a through hole is horizontally opened on the connecting head, and a screwdriver is used to assist the operation during disassembly, so that it can be conveniently connected to the mold to achieve stable fixation. A sliding sleeve is sleeved on the rod body of the operating rod, and the sliding of the sliding sleeve on the operating rod can drive the inertia block to generate inertial impact force, thereby helping demoulding, and the mold is pulled out by inertia. It has a simple structure and is easy to operate. Compared with existing demoulding tools, it reduces extrusion and ensures the yield rate. It can effectively improve the demoulding efficiency and reduce the difficulty of operation. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] The preferred embodiments of the present invention are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are only used to explain the technical principles of the present invention and are not intended to limit the protection scope of the present invention.

[0016] See also Figures 1 to 3 The embodiment of the utility model discloses an auxiliary demoulding tool, which mainly includes an operating rod 1, at the bottom of which a bottom block 3 is fixedly welded, the bottom block 3 is a rectangular metal block, and a connecting hole is provided in the middle of the bottom block 3, a connecting head 301 connected to the mold is detachably provided inside the connecting hole, the connecting hole is a threaded hole, and the connecting head 301 is a tapered threaded rod, which is connected with the hole on the mold, and the size of the holes of molds with different volumes is different. A suitable connecting head 301 can be replaced to match the mold connection, and a through hole 303 is horizontally opened on the connecting head 301. A screwdriver is used to assist the operation during disassembly. This design allows the tool to be easily connected to the mold to achieve stable fixation.

[0017] A sleeve 2 is sleeved on the rod body of the operating rod 1, and an inertia block 202 is arranged on the top of the sleeve 2 to increase the weight and increase the inertia during use. A pull rod 201 is horizontally arranged on the side wall of the sleeve 2, and a handle is arranged at the end of the pull rod 201. This design allows the operator to easily pull the pull rod 201 when it is necessary to slide the sleeve 2, thereby driving the sleeve 2 to move up and down. The sliding of the sleeve 2 on the operating rod 1 can drive the inertia block 202 to generate an inertial impact force. For molds that are tightly connected, multiple people can operate together to help demolding. An impact block 102 is also arranged on the upper part of the operating rod 1. The impact block 102 is arranged above the inertia block 202. When the sleeve 2 slides upward, the inertia block 202 will impact the impact block 102, thereby generating a greater impact force, which is helpful for demolding.

[0018] A toothed rubber ring is also provided inside the sliding sleeve 2. The toothed portion of the rubber ring abuts against the side of the operating rod 1, and the friction force is used to prevent the sliding sleeve 2 from sliding freely on the operating rod 1, so as to facilitate the control of the sliding sleeve 2 on the upper part of the operating rod 1, facilitate the user's operation, and improve convenience.

[0019] For the convenience of operation, a bending portion 101 for hand holding is also provided on the top of the operating rod 1. The bending portion 101 is bent toward the side of the operating rod 1 to form a horizontal U-shaped opening. When in use, the operator holds the operating rod 1 with one hand and rotates the bending portion 101 with the other hand, so that the connecting head 301 can be quickly connected to the mold. Not only can the tool be held more comfortably and stably, but also disassembly and assembly can be quickly achieved, which greatly speeds up the operating efficiency.

[0020] The bottom side ridges of the bottom block 3 are set to be arc-shaped. This design can reduce the friction with the mold during demoulding. A connecting ring 302 for fixing the connecting rope is also set on the top surface of the bottom block 3. For a mold with a longer length, when demoulding, first remove the connecting head 301, use the connecting rope to connect it to the connecting ring 302, and the other end of the connecting rope is connected to the mold. Then the bottom block 3 is placed on the ground or on the surface of the mold. The bottom block 3 is blocked by the foot or a tool, and the operating lever 1 is swung. The bottom block 3 forms an oblique upward pulling force on the mold through the connecting rope, thereby assisting demoulding and facilitating operation. The arc-shaped side ridges reduce the extrusion on the mold and the product, ensure the yield rate, and improve the production effect.

[0021] When in use, it is connected to the molding tool embedded in the product through the connecting head 301, and the hand-held pull rod 201 slides up and down, colliding upward with the inertia block 202, and the mold is pulled out by inertia. It has a simple structure and is easy to operate. Compared with existing demoulding tools, it reduces extrusion and ensures the yield rate. It can effectively improve the demoulding efficiency and reduce the difficulty of operation.
