Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of mold structures, and in particular to a mold structure which is easy to disassemble. Background Art
[0002] Multiple products in a processing plant may use a common core box mold. Multiple products are used at the same time, and the production scale is large. At the same time, due to product structure reasons, the pull-out blocks designed in the core box will scratch both sides of the core box every time the mold is opened and closed, causing serious wear and tear after long-term use. If maintenance requires the entire mold to be disassembled, it will go through tedious processes such as welding, processing, manual molding and assembly, which is costly and has a long cycle, which in turn leads to increased costs and reduced production efficiency. Utility Model Content
[0003] The utility model provides a mold structure that is easy to disassemble, which solves the problem in the related art that the core box is used for a long time, its two sides are greatly worn due to the pulling and drawing of the movable blocks, the subsequent maintenance cost is high, the steps are cumbersome, and the production efficiency is reduced.
[0004] The technical solution of the utility model is as follows:
[0005] A mold structure that is easy to disassemble, comprising:
[0006] a mold body having a mold cavity having a wear position;
[0007] A disassembly block is detachably arranged on the wear position.
[0008] As a further technical solution, the mold cavity is an open groove, and the mold cavity has the wear position at one end away from the opening.
[0009] As a further technical solution, the wear position is a stepped groove, the disassembly block is U-shaped, and the disassembly block is detachably arranged on the wear position by a fastener.
[0010] As a further technical solution, the disassembly block is a wear-resistant cast steel disassembly block.
[0011] As a further technical solution, gaps are formed between both ends of the disassembly block and the mold body.
[0012] As a further technical solution, the disassembly block includes:
[0013] A U-shaped main body and two connecting blocks, wherein the two connecting blocks are detachably arranged at the two ends of the U-shaped main body, and the gap is formed between the two connecting blocks and the mold main body.
[0014] As a further technical solution, both ends of the U-shaped body and the disassembly block have inclined mounting surfaces, which are in contact with each other, and the inclined mounting surfaces have connecting holes, and further include:
[0015] An expansion fastener passes through the connecting hole of the U-shaped body and the connecting hole of the disassembly block, and the expansion fastener is used to push the disassembly block toward the gap through the inclined mounting surface.
[0016] The working principle and beneficial effects of the utility model are:
[0017] In the utility model, the conventional mold core box structure is usually Figure 1 The left half of the mold will be worn to the inner wall surface away from the opening. This is because the pull-out block will scratch both sides of the core box every time the mold is opened and closed. Long-term use will cause serious wear and tear, and maintenance requires the mold to be disassembled as a whole, and go through tedious processes such as welding, processing, manual molding and assembly. In addition, the core box material of the traditional HT200 mold has poor weldability, and the mold repair cost is high. The service life after mold repair is very short, and the mold will be worn out again after about 2,000 molds, and the production efficiency is very low. Therefore, a mold structure that is easy to disassemble is designed.
[0018] like Figure 1 In the right half of the figure, the mold body is placed on the wear position away from the opening, that is, the inner wall surface of the mold cavity away from the opening, and a disassembly block for processing products with a matching shape is installed accordingly, which is convenient for use in combination with the mold cavity. The disassembly block can be made of wear-resistant cast steel and other materials to improve the overall wear resistance. During installation, fasteners such as bolts can be used to complete the installation, which not only ensures that workers can use the mold body to quickly produce products, but also ensures that the bolts can be quickly turned to replace the disassembly block after wear.
[0019] This mold structure greatly reduces the cost of mold repair, and the redundant disassembly blocks are processed in advance. When replacing, you only need to unscrew the bolts to replace them. There is no need to stop production or disassemble the mold, which shortens the maintenance time. The change in material also greatly increases the service life. At the same time, the wear-resistant cast steel disassembly blocks can be nitrided to increase their surface wear resistance.
[0020] Specifically, it is faster and more convenient to locate the position of the disassembly block. A wear position in the form of a stepped groove is used, and a stepped portion is also processed at the corresponding position on the bottom of the disassembly block. Then, when installing the disassembly block, it can be directly aligned with the stepped groove. The disassembly block is set to be U-shaped to adapt to the shape of the product to be processed in the mold cavity, so as to avoid interference after being installed in the wear position.

For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.
[0031] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.
[0032] Reference Figure 1~Figure 5 , which is the first embodiment of the utility model, proposes a mold structure that is easy to disassemble, including: a mold main body 1, the mold main body 1 has a mold cavity 101, and the mold cavity 101 has a wear position 102; a disassembly block 2, and the disassembly block 2 is detachably arranged on the wear position 102.
[0033] Furthermore, the mold cavity 101 is an open groove, and the mold cavity 101 has the wear position 102 at one end away from the opening.
[0034] Further, the wear position 102 is a stepped groove, the disassembly block 2 is U-shaped, and the disassembly block 2 is detachably arranged on the wear position 102 by a fastener.
[0035] Furthermore, the disassembly block 2 is a wear-resistant cast steel disassembly block.
[0036] In this embodiment, Figures 1 to 3 As shown, the traditional mold core box structure is usually Figure 1 The left half of the mold will be worn to the inner wall surface away from the opening. This is because the pull-out block will scratch both sides of the core box every time the mold is opened and closed. Long-term use will cause serious wear and tear, and maintenance requires the mold to be disassembled as a whole, and go through tedious processes such as welding, processing, manual molding and assembly. In addition, the core box material of the traditional HT200 mold has poor weldability, and the mold repair cost is high. The service life after mold repair is very short, and the mold will be worn out again after about 2,000 molds, and the production efficiency is very low. Therefore, a mold structure that is easy to disassemble is designed.
[0037] like Figure 1 In the right half of the figure, the mold body 1 is placed on the wear position 102 away from the opening, that is, the inner wall surface of the mold cavity 101 away from the opening, and a disassembly block 2 for processing products with a matching shape is installed accordingly, which is convenient for use in combination with the mold cavity 101. In order to improve the overall wear resistance, the disassembly block 2 can be made of wear-resistant cast steel and other materials. During installation, fasteners such as bolts can be used to complete the installation, which not only ensures that workers can use the mold body 1 to quickly produce products, but also ensures that the bolts can be quickly tightened to replace the disassembly block 2 after wear.
[0038] This mold structure greatly reduces the cost of mold repair, and the redundant disassembly blocks 2 are processed in advance. When replacing, only the bolts need to be unscrewed for replacement. There is no need to stop production or disassemble the mold, which shortens the maintenance time. The change in material also greatly increases the service life. At the same time, the wear-resistant cast steel disassembly block 2 can be nitrided to increase its surface wear resistance.
[0039] Specifically, the position of the disassembly block 2 can be positioned more quickly and conveniently by using a wear position 102 in the form of a stepped groove, and a stepped portion is also processed at the corresponding position on the bottom of the disassembly block 2, so that the step groove can be directly aligned when installing the disassembly block 2; and the disassembly block 2 is set to be U-shaped, in order to adapt to the shape of the product to be processed by the mold cavity 101, so as to avoid interference after being installed at the wear position 102.
[0040] Furthermore, gaps 3 are formed between both ends of the disassembly block 2 and the mold body 1 .
[0041] Furthermore, the disassembly block 2 includes: a U-shaped main body 201 and two connection blocks 202 . The two connection blocks 202 are detachably arranged at both ends of the U-shaped main body 201 , and the gap 3 is formed between the two connection blocks 202 and the mold main body 1 .
[0042] Furthermore, both ends of the U-shaped body 201 and the disassembly block 2 have inclined mounting surfaces 203, which are in contact with each other. The inclined mounting surface 203 has a connecting hole 204, and also includes: an expansion fastener 4, which passes through the connecting hole 204 of the U-shaped body 201 and the connecting hole 204 of the disassembly block 2, and the expansion fastener 4 is used to push the disassembly block 2 toward the gap 3 through the inclined mounting surface 203.
[0043] In this embodiment, Figures 3-5 As shown, due to the shape of the product to be processed by the mold cavity 101, the disassembly block 2 is U-shaped and is located on the wear position 102 of the mold cavity 101 away from the opening end. As a result, it is inevitable that gaps 3 are formed between both ends of the U-shaped disassembly block 2 and the mold body 1, resulting in some flash being produced from the gap 3 when the product is produced in the mold cavity 101. In order to solve this problem and reduce the appearance of the gap 3 as much as possible and reduce the width of the gap 3, it is necessary to install the disassembly block 2 closely in the direction close to the gap 3. Specifically, the disassembly block 2 is divided into two parts, and the wedge block principle is used to form two connecting blocks 202 and a U-shaped body 201. The U-shaped body Both ends of 201 and the disassembly block 2 have inclined mounting surfaces 203, and are connected by a connecting hole 204 that penetrates the two through an expansion fastener 4. This design enhances the structural stability between the disassembly block 2 and the mold body 1. At the same time, in the installation sequence, the connecting block 202 is first positioned through the step groove, and then the U-shaped body 201 is positioned through the inclined mounting surface 203 and the step groove. This can make the overall installation of the disassembly block 2 more convenient. At the same time, the inclined mounting surface 203 can better press the connecting block 202 to be tightly connected in the direction of the gap 3, thereby minimizing the appearance of the gap 3 and reducing the width of the gap 3. Finally, the disassembly block 2 and the mold body 1 are connected through fasteners.
[0044] Since the U-shaped main body 201 and the connecting block 202 need to be connected to avoid the mismatch between the connecting holes 204 of the two, which would result in the inability to connect them smoothly through fasteners, expansion bolts are used to reduce the risk of accidental loosening of the disassembly block 2 during use, thereby improving the safety and reliability of the operation. In summary, the design of the U-shaped main body 201, the two connecting blocks 202 and the expansion fasteners 4 not only significantly improves the convenience and safety of the mold structure that is easy to disassemble, but also enhances the economy and applicability of the equipment, providing a more efficient and reliable solution for mold production and maintenance.
[0045] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
