Description

Technical Field

[0001] This utility model relates to the field of mold processing technology, specifically to an integrated wooden mold. Background Technology

[0002] Wooden molds are widely used in various scenarios due to their advantages of low cost and high processing flexibility. For example, the molds used for slurry pumps in mining are made of wood.

[0003] For large wooden molds, traditional processes often employ a modular structure. This involves first processing multiple small wooden mold units, which are then assembled into a complete mold. While this modular approach reduces the overall stress on the mold and facilitates its transport, it also presents a challenge. During mold manufacturing, dimensional deviations can easily occur at the joints between the smaller units, affecting the overall shape and integrity of the final product during sand casting.

[0004] Furthermore, in order to transport the individual small units and the assembled complete wooden mold during sand casting, mounting holes such as screw holes need to be pre-made in the wooden mold. Then, after each small unit is processed, lifting rings or other mold-lifting components are installed in the mounting holes. This type of structure is not only time-consuming and labor-intensive, but also requires repeated disassembly and reassembly of the mold-lifting components during transport. Therefore, it may damage the mounting holes, increasing the risk of the mold falling during lifting and transport, and even damaging the surrounding structure of the mounting holes, thus increasing the risk of mold damage. Utility Model Content

[0005] The purpose of this utility model is to provide an integrated wooden mold to solve the technical problems of existing wooden molds, such as the dimensional deviations that are easy to occur at the splicing points of the split small units, and the risk of falling or / and mold damage that may be caused by external mold-lifting components during transportation or mold lifting.

[0006] To achieve the above objectives, the present invention proposes the following technical solution:

[0007] An integrated wooden mold includes a mold body, and several longitudinal skeletons and several mold-lifting components that cooperate with the mold body;

[0008] The mold body is a wooden cavity structure, with each longitudinal skeleton placed at intervals within the mold body, and the upper and lower ends of each longitudinal skeleton abutting against the inner wall of the mold body; wherein, some of the longitudinal skeletons are provided with the mold-lifting components;

[0009] The mold-lifting component includes a mold-lifting body and lifting holes respectively opened at the upper and lower ends of the mold-lifting body; wherein, the mold-lifting body is fixed on the corresponding longitudinal frame, and the mold body is provided with a lifting groove at the corresponding position of any lifting hole; wherein, the part of the mold-lifting body with the lifting hole is built into the corresponding lifting groove.

[0010] Furthermore, the longitudinal frame includes several stacking units; wherein, each stacking unit is stacked sequentially, and the upper surface of the uppermost stacking unit and the lower surface of the lowermost stacking unit both abut against the inner wall of the mold body; wherein, adjacent stacking units are fixedly arranged.

[0011] Furthermore, it includes several transverse skeletons arranged at intervals; each transverse skeleton is fixed to each longitudinal skeleton at a corresponding position, and the left and right end faces of each transverse skeleton abut against the inner wall of the mold body.

[0012] Furthermore, it includes: several inclined support members; each inclined support member is staggered and fixed to each transverse frame and each longitudinal frame at the corresponding position.

[0013] Furthermore, all longitudinal frames, transverse frames, and diagonal supports are made of wood.

[0014] Furthermore, the main body of the mold is a steel plate.

[0015] Furthermore, the mold-lifting body is a stainless steel mold-lifting template.

[0016] Furthermore, it includes several fasteners; the mold-forming body has several first fixing holes, and the longitudinal skeleton at the corresponding position has several second fixing holes; wherein, the first fixing holes and the second fixing holes are coaxially arranged in a one-to-one correspondence, and each fastener is sequentially inserted into the corresponding first fixing hole and second fixing hole.

[0017] Furthermore, the left and right sides of the part of the mold-lifting body with lifting holes are embedded in the mold body.

[0018] Furthermore, the longitudinal skeletons are arranged in a matrix within the mold body.

[0019] Furthermore, it includes four mold-lifting components, symmetrically arranged at the four corners of the mold body.

[0020] Beneficial effects:

[0021] This technical solution provides a novel wooden mold that simultaneously addresses the technical shortcomings of existing modular wooden molds, such as the tendency for dimensional deviations to occur at the joints of the modular small units, and the risk of external mold-lifting components causing the mold to fall during transport or / and be damaged.

[0022] The mold includes a mold body, and several longitudinal skeletons and several mold-lifting components that cooperate with the mold body. The mold body is a wooden hollow structure, with each longitudinal skeleton spaced apart within the mold body, and the upper and lower ends of each longitudinal skeleton abutting against the inner wall of the mold body; wherein, some of the longitudinal skeletons are provided with the mold-lifting components. Each mold-lifting component includes a mold-lifting body and lifting holes respectively opened at the upper and lower ends of the mold-lifting body; wherein, the mold-lifting body is fixed to the corresponding longitudinal skeleton, and the mold body has a lifting groove at a position corresponding to any lifting hole; the portion of the mold-lifting body with the lifting hole is built into the corresponding lifting groove.

[0023] Therefore, this technical solution integrates the wooden mold into a single unit, effectively solving the deformation problem at the joints of split molds and thus avoiding structural defects in the molding sand during subsequent sand casting. Furthermore, considering the increased overall stress on the wooden mold due to the integrated design, longitudinal skeletons are incorporated to support the hollow mold body, preventing overall mold deformation defects. Additionally, the built-in mold-lifting component avoids the need for repeated disassembly of the mold-lifting parts, extending the mold's lifespan. Moreover, since the mold-lifting components are typically made of rigid materials such as steel, their fixation to the longitudinal skeletons further enhances the overall support strength of the mold body.

[0033] Traditional methods for manufacturing large wooden molds employ a modular structure, breaking the mold down into multiple smaller units. This reduces the overall stress on the mold, decreases the size of individual units, and lowers transportation costs. The smaller units also facilitate demolding. However, modular wooden molds present several problems during the shaping stage. For example, deformation easily occurs at the connections between smaller units, leading to dimensional deviations and gaps at the joints. Furthermore, traditional wooden molds often utilize pre-embedded screws and external bolts as lifting mechanisms for transportation and demolding. While this method makes good use of existing structures and saves time and manufacturing costs, it requires replacing internal screws after repeated use, resulting in long-term time-consuming and labor-intensive processes, and potentially damaging the mold. Therefore, existing wooden molds have shortcomings in overall shaping, demolding, and subsequent use. This embodiment aims to design an integrated wooden mold to solve these technical problems.

[0034] The integrated wooden mold disclosed in this utility model will be further described in detail below with reference to the embodiments shown in the accompanying drawings.

[0035] Combination Figures 1-3 As shown, this embodiment specifically designs a wooden mold for a slurry pump in order to illustrate the structure of this type of wooden mold described in this embodiment.

[0036] The mold includes a mold body 1, at least one longitudinal frame 2, and at least one mold-lifting component 3. Each longitudinal frame 2 and each mold-lifting component 3 is based on the mold body 1. Specifically, the mold body 1 is a wooden cavity structure, and its shape is consistent with the slurry pump to be cast. In actual processing, pine wood is selected as the material for the mold body 1. Each longitudinal frame 2 is spaced apart within the mold body 1, and the upper and lower ends of each longitudinal frame 2 abut against the inner wall of the mold body 1. Simultaneously, some of the longitudinal frames 2 are equipped with the mold-lifting components 3.

[0037] In this embodiment, the mold body 1 is first stacked during processing, and then its shape is shaped using a machine tool. Therefore, each longitudinal frame 2 includes several stacking units 21. Specifically, the stacking units 21 are stacked sequentially, with the upper surface of the uppermost stacking unit and the lower surface of the lowermost stacking unit both abutting against the inner wall of the mold body 1. Adjacent stacking units 21 are fixedly arranged. Specifically, adjacent stacking units 21 are fixed together using nails. Furthermore, the stacking units 21 are also made of wood.

[0038] In a preferred embodiment, the longitudinal skeletons 2 are arranged in a matrix within the mold body 1 to provide strong support for all parts within the mold body 1, thereby preventing deformation of the mold body 1 and affecting the subsequent processing of the slurry pump.

[0039] Continuing, considering the need to improve support strength, as a further preferred embodiment, several transverse frames 4 and several diagonal support members 5 are also provided. In the specific structural arrangement, the transverse frames 4 are spaced apart, and each transverse frame 4 is fixed to a corresponding longitudinal frame 2, with the left and right end faces of each transverse frame 4 abutting against the inner wall of the mold body 1. In this embodiment, five longitudinal frames 2 and one transverse frame 4 are provided on a corresponding longitudinal section of the wooden body 1, with the transverse frame 4 located at the middle of the longitudinal section. The diagonal support members 5 are staggered and fixed to the corresponding transverse frames 4 and longitudinal frames 2. This achieves multi-point support in various directions within the mold body 1. In specific implementation, each transverse frame 4 and each diagonal support member 5 is a wooden structure, and each longitudinal frame, each transverse frame, and each diagonal support member is fixed with nails.

[0040] Correspondingly, to ensure stability during hoisting, four lifting components 3 are provided, symmetrically arranged at the four corners of the mold body 1. Each lifting component 3 includes a lifting body and lifting holes 31 respectively opened at the upper and lower ends of the lifting body. Specifically, the lifting body is fixed to the corresponding longitudinal frame 2, and the mold body 1 has a lifting groove 11 at the corresponding position of any lifting hole 31. Specifically, the portion of the lifting body with the lifting hole 31 is housed within the corresponding lifting groove 11.

[0041] In practical implementation, to ensure the structural strength of the mold-lifting component 3, the mold-lifting body is set to a mold-lifting steel plate. Specifically, considering service life, the mold-lifting body is further set to a stainless steel mold-lifting plate.

[0042] Meanwhile, to ensure the reliability of the connection between the mold-lifting component 3 and the longitudinal frame 2, thereby improving the reliability of subsequent mold lifting and hoisting and avoiding the risk of mold falling, several fixing components are also included. Correspondingly, several first fixing holes are formed on the mold-lifting body, and several second fixing holes are formed on the longitudinal frame 2 at corresponding positions; the first fixing holes and second fixing holes are coaxially arranged in a one-to-one correspondence. The fixing components are then sequentially inserted into the corresponding first fixing holes and second fixing holes to achieve a fixed connection between the mold-lifting component 3 and the longitudinal frame 2. Specifically, the fixing components are bolts.

[0043] As a specific implementation, in order to reduce the structural impact of setting the lifting groove 11 on the mold body 1, the left and right sides of the part of the mold-lifting body with the lifting hole 31 are both embedded in the mold body 1. At this time, only the lifting hole 31 is exposed in the lifting groove 11, so as to ensure that the size of the lifting groove 11 is minimized.

[0044] In practical implementation, during the wooden mold making stage, firstly, wooden boards are stacked according to the outline dimensions of the wooden mold. During the first stacking process, adjacent wooden boards are fixed with nails. Preferably, the first stacking refers to the stacking of the lower half of the wooden mold, and after the first stacking, a machining tool is used to process it to obtain the first part corresponding to the mold body 1. Secondly, after the first part of the mold body 1 is processed, it is flipped over, and wooden boards are stacked a second time on the basis of the first part. Simultaneously, stacking units 21 are stacked inside and fixed with nails between adjacent stacking units to form a longitudinal frame 2, and a lifting member 3 is fixed on the pre-selected longitudinal frame 2; after the second stacking, a machining tool is used to process it to obtain the second part corresponding to the mold body 1. At this time, the first part and the second part constitute the complete mold body 1. Finally, lifting grooves 11 are opened at corresponding positions on the mold body 1, and the transverse frame 4 and diagonal support members 5 are fixed at pre-set positions inside the mold body 1; thus completing the entire wooden mold making process.

[0045] In the above process, through the fixed longitudinal frame 2, transverse frame 4, oblique support 5, stainless steel lifting template and large-area connection with mold body 1, multi-point positioning and fixation are achieved, which can bear the weight of mold body 1 and avoid the defects of overall mold deformation introduced by the one-piece design. The embedded lifting components also avoid mold repair or scrapping caused by external lifting devices, thus extending the service life of the mold.

[0046] When using the wooden mold obtained above for molding sand, in the specific box-turning molding stage, the wooden mold is as follows: Figure 3 The sand box 7 is placed and covers the wooden mold from top to bottom. The molding sand 6 is filled into the gap between the sand box 7 and the wooden mold. After curing, the sand box 7 is flipped over, and the crane connecting hook is connected to the lifting hole of the mold-lifting part 3 in the wooden mold. The mold is lifted efficiently and conveniently, avoiding the use defects that may be caused by repeated disassembly of the mold-lifting part.

[0047] Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Those skilled in the art to which this invention pertains can make various modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of this invention shall be determined by the claims.
