Description

TECHNICAL FIELD

[0001] The utility model relates to the field of production equipment, and specifically, in particular to a mould for producing biscuits. BACKGROUND

[0002] For a long time, the traditional biscuit production mould with its fixed and unchangeable mould cavity shape has become one of the bottlenecks restricting the development of the industry. These moulds are usually engraved according to specific specifications and designs, and once they are cast, the shape, size and even the pattern of the mould cavity are permanently solidified and cannot be changed. This means that when the production line needs to switch to produce biscuits of different shapes, sizes or patterns, it must spend time and resources to customize a new mould. This process not only consumes a lot of capital, but also often involves a long waiting period, which seriously affects the flexibility of the production line and the speed of responding to the market.

[0003] In the face of the growing demand for personalized and customized products in the market, biscuit manufacturers have begun to seek a breakthrough from the constraints of traditional moulds. They realize that in order to stand out in the competitive market environment, they must have the ability to quickly change production to meet the changing tastes of consumers. This requires biscuit moulds to have higher plasticity and adaptability, and to be able to flexibly adjust the shape, size and pattern of the product in a short period of time to meet the changing market demand. SUMMARY

[0004] Therefore, the utility model provides a mould for producing biscuits, which can quickly replace the mould cover plate with different specifications of mould cavities, thereby producing biscuits of different shapes, sizes and even patterns to meet the diversified consumer demand. Whether it is a classic heart shape, animal shape or innovative geometric pattern, only the corresponding mould cover plate needs to be replaced to easily achieve personalized customization, providing unlimited creative space for enterprises, and the mould base can be universal, only the mould cover plate and mould cavity need to be redesigned, saving the amount of mould material.

[0005] The utility model achieves the purpose through the following technical solutions:

[0006] A mould for producing biscuits, comprising a mould base, a mould cover plate covering the mould base and being detachably connected with the mould base, a plurality of mould cavities in the shape of biscuits arranged on the mould cover plate, the mould cover plate being provided with a positioning column, the mould base being provided with a positioning groove matched with the positioning column, and the mould cover plate being detachably connected with the mould base through a threaded part.

[0007] The mold is unique in that it is not limited to the production of a single type of biscuit. By flexibly replacing the mold cavity, manufacturers can quickly replace the mold cover plate with different specifications according to market trends and personal preferences, producing biscuits of different shapes, sizes, and even patterns to meet diverse consumer needs. Whether it's a classic heart shape, animal shape, or innovative geometric shape, simply replace the corresponding mold cover plate to easily achieve personalized customization, providing unlimited creative space for businesses. The mold base can be used universally, and only the mold cover plate and mold cavity need to be redesigned, saving on mold material usage. The mold cover plate and mold base are detachably connected, simplifying the process of daily cleaning and replacing the mold cavity, and facilitating targeted maintenance and replacement by maintenance personnel, without the need for complete maintenance and replacement, saving costs and extending the overall service life of the mold. The combination of the alignment column and the alignment slot ensures that the mold cover plate can quickly find its position when placed, without the need for a tedious manual correction process, greatly saving time and labor costs and significantly improving the speed and accuracy of the production line.

[0008] Preferably, the number of alignment slots is two, and the two alignment slots are arranged along the center line of the mold base; the number of alignment columns is two, and the two alignment columns are arranged along the center line of the mold cover plate.

[0009] The two sets of alignment mechanisms are arranged in the alignment slots and alignment columns arranged on the center lines of the mold base and the mold cover plate. This double-column and double-slot layout strategy provides double safety protection for the assembly of the mold. Compared with a single positioning device, this design significantly increases the number of contact points, thereby greatly enhancing the stability of the mold after it is closed at the physical level. This means that during the biscuit forming process, even if it is subjected to the impact of high-speed operation, the mold can maintain its original position unchanged, significantly reducing deviations and ensuring that each biscuit has a regular and consistent shape, thereby ensuring the quality of the finished product. The design principle of the double-column and double-slot design also lies in the balance and dispersion of force. The two alignment columns are evenly distributed on the center line of the mold cover plate, which not only helps to evenly apply pressure to each mold cavity, but also ensures that the stress on each part of the mold is evenly distributed during the entire production process, whether it is heating, cooling, or demolding.

[0010] Preferably, the mold cover plate has a first screw hole, the mold base has a second screw hole, and the threaded part is locked in the first screw hole and the second screw hole.

[0011] The threaded piece, as a key element connecting the mold cover plate and the mold base, through the first screw hole and the second screw hole respectively opened on the mold cover plate and the mold base, builds a solid and flexible connection system. This design breaks the limitations of traditional mechanical fixation, and uses the screwing force of the threaded piece to achieve close fitting, providing additional stability for the mold. Compared with conventional buckles or other fixing methods, the threaded piece connection has better shock resistance and durability, can maintain high precision in frequent production cycles, reduce the loosening of parts caused by vibration or temperature change, and thus ensure the continuity of production and the consistency of products. Another outstanding advantage of the threaded piece locking mechanism is its speed. Operators only need to use simple tools such as screwdrivers or wrenches to complete the assembly or disassembly of the mold within a few minutes. This convenience not only saves a lot of labor costs, but also enables the mold to be quickly inspected and repaired when it encounters a fault, greatly shortening the downtime and directly and positively affecting the overall efficiency of the production line. In addition, this design also facilitates the interchangeability of different parts of the mold, providing strong support for the diversified production of products and the rapid adaptation to changes in market demand.

[0012] Preferably, the number of threaded pieces is one, and three points are arranged in line with two alignment columns.

[0013] The number of threaded pieces is set to one, and together with two alignment columns, it forms a three-point-in-line layout. The single threaded piece acts as a fulcrum, adjusting the overall state of the mold by tightening or loosening, ensuring the reliable combination between the mold cover plate and the base. Even in harsh working environments with high speed and high frequency vibration, the structure remains stable and consistent, demonstrating an efficient and delicate design philosophy.

[0014] Preferably, the number of threaded pieces is two, and four points are arranged in line with two alignment columns.

[0015] When the number of threaded pieces increases to two, together with two alignment columns, they form a four-point-in-line architecture, which can also improve the stability and reliability of the mold system, making the connection between the mold cover plate and the base more secure. Especially when facing higher strength requirements or larger-scale production operations, they can better share the load, reduce stress concentration on a single part, significantly prolong the service life of the mold, reduce maintenance frequency, and improve overall production efficiency and economic benefits.

[0016] Preferably, the number of mold cavities is multiple, and multiple mold cavities are evenly arranged on the mold cover plate.

[0017] The plurality of cavities are evenly arranged on the die cover plate, so that each cavity can obtain the same heat and pressure distribution, and the biscuits at the edge and the center can enjoy the same processing conditions during processing, the uniform distribution of the cavities can also help to improve the material utilization rate, reduce the waste rate, and further optimize the cost structure, thereby creating greater economic benefits for the production enterprises.

[0018] Preferably, the cavity is integrally formed with the die cover plate.

[0019] The cavity is integrally formed with the die cover plate, so that the cavity is directly integrated into the die cover plate, and no additional welding or bonding process is needed, the overall strength and durability of the die are significantly enhanced, the risk of component separation caused by long-term use is greatly reduced, and the continuity and stability of production are ensured.

[0020] Preferably, the die base is provided with a fixing hole, and the die cover plate is provided with a matching hole matched with the fixing hole.

[0021] The fixing hole on the die base and the matching hole on the die cover plate constitute the main fixing structure of the overall die, and ensure the connection reliability of the overall die and the equipment.

[0022] The beneficial effects of the utility model compared with the prior art are:

[0023] The die for producing biscuits of the utility model is not limited to single-form biscuit production, and through flexible replacement of the cavity, manufacturers can quickly replace the die cover plate with different specifications of the cavity according to market trends and personal preferences, so as to produce biscuits with different shapes, sizes and even patterns, and meet diversified consumer demand. Whether it is a classic heart shape, an animal shape or an innovative geometric shape, only the corresponding die cover plate needs to be replaced, so that personalized customization can be easily realized, and unlimited creative space is brought to enterprises, and the die base can be universal, only the die cover plate and the cavity need to be redesigned, so that the material consumption of the die is saved. The die cover plate and the die base can be detachably connected, which simplifies the process of daily cleaning and cavity replacement, and also facilitates targeted maintenance and replacement of maintenance personnel, without the need for complete maintenance and replacement, thereby saving costs and prolonging the overall service life of the die. The combination of the alignment column and the alignment groove ensures that the die cover plate can quickly find the position when placed, without the need for a tedious manual correction process, thereby greatly saving time and labor costs and significantly improving the speed and accuracy of the production line.

[0033] The technical solutions in the present application will be described below with reference to the drawings. Embodiment 1

[0034] The embodiment provides a mold for producing biscuits, which comprises a mold base 100, a mold cover plate 200 which is detachably connected to the top of the mold base 100, and a plurality of mold cavities 300 in the shape of biscuits which are arranged on the mold cover plate 200. The mold cover plate 200 is provided with alignment columns 210, and the mold base 100 is provided with alignment grooves 110 which cooperate with the alignment columns 210. The mold cover plate 200 is detachably connected to the mold base 100 by means of threaded fasteners 400.

[0035] The uniqueness of the mold lies in that it is not limited to the production of biscuits in a single shape. By flexibly replacing the mold cavities 300, manufacturers can quickly replace the mold cover plate 200 with different specifications of mold cavities 300 according to market trends and personal preferences, so as to produce biscuits of different shapes, sizes and even patterns to meet the diversified needs of consumers. Whether it is a classic heart shape, an animal shape, or an innovative geometric shape, it can be easily customized by replacing the corresponding mold cover plate 200, which brings unlimited creative space to enterprises. The mold base 100 can be used universally, and only the mold cover plate and the mold cavity need to be redesigned, which saves the amount of mold material. The detachable connection between the mold cover plate 200 and the mold base 100 simplifies the process of daily cleaning and replacement of the mold cavities 300, and also facilitates targeted maintenance and replacement by maintenance personnel, without the need for complete maintenance and replacement, which saves costs and prolongs the overall service life of the mold.

The number of alignment columns 210 is two, and the two alignment columns 210 are arranged along the center line of the mold cover plate 200.

[0037] Two sets of alignment mechanisms are configured, respectively located in the alignment grooves 110 and alignment columns 210 set on the center line of the mold base 100 and the mold cover plate 200. This double-column double-groove layout strategy provides double security for the assembly of the mold. Compared with a single positioning device, this design significantly increases the number of contact points, thereby greatly enhancing the stability of the mold after closing at the physical level. This means that during the biscuit forming process, even in the face of high-speed impact, the mold can maintain its original position unchanged, significantly reducing deviations, ensuring that each biscuit has a regular and consistent shape, and the quality of the finished product is effectively guaranteed. The design principle of the double-column double-groove also lies in the balance and dispersion of force. Two alignment columns 210 are evenly distributed on the center line of the mold cover plate 200, which not only helps to evenly apply pressure to each mold cavity 300, but also ensures that the stress on each part of the mold is evenly distributed throughout the production process, whether it is heating, cooling or demolding stage.

[0039] The threaded part 400, as a key element connecting the mold cover plate 200 and the mold base 100, through the first screw hole 220 and the second screw hole 120 respectively opened on the mold cover plate 200 and the mold base 100, builds a connection system that is both solid and flexible. This design breaks the limitations of traditional mechanical fixation, using the screwing force of the threaded part 400 to achieve a tight fit, providing additional stability to the mold. Compared with conventional buckles or other fixing methods, the threaded part 400 connection has better shock resistance and durability, can maintain high precision in frequent production cycles, reduce the loosening of parts due to vibration or temperature changes, and thus ensure the continuity of production and the consistency of products. Another outstanding advantage of the threaded part 400 locking mechanism is its speed. Operators only need to use simple tools such as screwdrivers or wrenches to complete the assembly or disassembly of the mold within a few minutes. This convenience not only saves a lot of labor costs, but also allows the mold to be quickly inspected and repaired when it fails, greatly shortening the downtime, which has a direct and positive impact on improving the overall efficiency of the production line. In addition, this design also facilitates the interchangeability of different components of the mold, providing strong support for the diversified production of products and the rapid adaptation to changes in market demand.

[0040] In this embodiment, the number of threaded parts 400 is one, and the three-point collinear arrangement with the two alignment columns 210.

[0041] The number of the threaded part 400 is set to one, and together with the two alignment columns 210, it forms a three-point one-line layout. The single threaded part 400 plays the role of fulcrum, and by tightening or loosening, it adjusts the overall state of the mold, ensuring the reliable combination between the mold cover plate 200 and the base. Even in harsh working environments with high-speed operation and high-frequency vibration, it can maintain the stability and consistency of the structure, and it shows the efficient and delicate design philosophy.

[0042] In this embodiment, the number of mold cavities 300 is 2, and the 2 mold cavities 300 are evenly arranged on the mold cover plate 200.

[0043] The 2 mold cavities 300 are evenly arranged on the mold cover plate 200, ensuring that each mold cavity 300 can obtain the same heat and pressure distribution. During the processing, whether it is the edge or the center of the biscuit, it can enjoy consistent processing conditions. The uniform distribution of the mold cavities 300 also helps to improve material utilization and reduce scrap rates, thereby optimizing the cost structure and creating greater economic benefits for production enterprises.

[0044] In this embodiment, the mold cavities 300 are integrally formed with the mold cover plate 200.
