Description

TECHNICAL FIELD

[0001] The utility model relates to a shoe mold, concretely relates to a shoemaking hot-pressing mold, which is provided with a flow space for flowing heating or cooling medium. BACKGROUND

[0002] At present, in the shoemaking industry, hot-pressing molds and hot-pressing forming processes are commonly used for manufacturing soles and part of uppers, as shown in Figures 1 to 4 The main manufacturing process is to first put a rough blank, then heat, and then cool and shape. In the product manufacturing process, the heating and cooling of the mold commonly use electricity, steam, liquid heating or water pouring cooling methods. The specific process is as follows: on the A machine table, the mold frame plate is heated by electric heating or heat-conducting steam / liquid or the mold is directly heated; then the mold is moved to the B machine table, and the mold frame plate and / or the mold surface is poured with water

[0003] (normal temperature or frozen water), so as to cool the mold and the product in the mold, and achieve the purpose of product shaping.

[0004] The time is referenced to medium-difficulty products, and the production operation process mainly includes the following:

[0005] The rough blank is put in for 20 seconds;

[0006] The mold is heated for 500 seconds;

[0007] The mold is transferred to the machine table or the hole position for 20 seconds;

[0008] The mold is cooled for 500 seconds;

[0009] The product is taken out and arranged for 20 seconds;

[0010] The mold is cleaned for 20 seconds.

[0011] As can be seen, the heating and cooling of the mold account for 93% of the whole process.

[0012] This process has many deficiencies, including:

[0013] The heating and cooling resources are wasted, and the mold frame plate and the surrounding structure do not need to be cooled, but this process cannot be avoided.

[0014] The heating and cooling method is conducted from the outside of the mold to the inside of the mold, and finally contacts the product (referring to the sole or the upper, the same below), which is slow in time and low in efficiency. For example, the surface of the mold is heated to 150 DEG C, but the product inside is still only 90 DEG C, or the surface of the mold is cooled to 30 DEG C, but the product inside is still 80 DEG C.

[0015] Water cooling results in serious waste of water resources, because the mold is heated to about 160℃ and then watered, which makes the production workshop foggy all the year round. A production workshop with dozens of people can waste more than 1000 tons of water per month.

[0016] The water cooling method does not use the body of the worker and the workshop environment. A large amount of fog and splashing water makes it difficult to improve the working environment, and a poor environment inevitably makes it difficult to recruit workers.

[0017] The water cooling method causes water to enter the product surface inside the mold, which may contaminate the appearance effect of the product; if the product is formed with other accessories, it may even cause product quality problems.

[0018] The water cooling method directly reduces the service life of the mold. The main body of the mold is generally made of aluminum, but some parts of the structure are made of iron, such as front end fasteners and clamps, which are made of iron (see Figure 3 、 Figure 4 ), which are prone to rust and corrosion due to long-term exposure to water.

[0019] Water and pollutants can enter the exhaust hole, which may cause the hole to be blocked, causing mold maintenance and product defects.

[0020] The water cooling method requires a drainage channel to be placed under the operating machine, and the operating machine and the related equipment nearby are in a humid environment for a long time, which affects the service life of the equipment.

[0021] The mold and the machine are always in a state of being watered, and the heating method and the control switch need to use power, which is prone to electric shock accidents. Practical new content

[0022] In order to solve the above problems, the utility model discloses a shoe hot-pressing mold, hollowing the inside of the mold, so that the cold and hot medium is heated and cooled from the inside of the mold, thereby greatly shortening the heating and cooling process, improving production efficiency and reducing production cost, and improving operation and workshop environment.

[0023] The technical scheme adopted by the utility model to achieve the above-mentioned purpose is:

[0024] A shoe hot-pressing mold, comprising an upper cover and a bottom plate, the upper cover and the bottom plate are folded to form a hot-pressing mold cavity for shoe production, a flow-through space for accommodating a heating or cooling medium is arranged in the upper cover and / or the bottom plate, and the flow-through space surrounds the hot-pressing mold cavity or is located on one side of the hot-pressing mold cavity.

[0025] As a further improvement of the utility model, the upper cover and the bottom plate are respectively provided with an inlet and an outlet connected with the flow-through space for conveying the heating or cooling medium.

[0026] As a further improvement of the utility model, the upper cover comprises a first cover plate and a second cover plate, the first cover plate and the second cover plate are folded to form the flow-through space; a sealing rubber strip is arranged at the contact surface of the first cover plate and the second cover plate.

[0027] As a further improvement of the utility model, the bottom plate comprises a first plate and a second plate, the first plate and the second plate are folded to form the flow-through space; a sealing rubber strip is arranged at the contact surface of the first plate and the second plate.

[0028] As a further improvement of the utility model, it further comprises a middle frame, the middle frame is located between the upper cover and the bottom plate, the upper cover, the middle frame and the bottom plate are folded to form the hot-pressing die cavity, the flow-through space for containing the heating or cooling medium is arranged in the middle frame, a sealing rubber strip is arranged at the contact surface of the middle frame and the bottom plate, and the flow-through space surrounds the hot-pressing die cavity or is located at one side of the hot-pressing die cavity.

[0029] As a further improvement of the utility model, the middle frame is provided with an inlet and outlet connected with the flow-through space and used for conveying the heating or cooling medium.

[0030] As a further improvement of the utility model, the upper cover, the bottom plate and the middle frame are provided with exhaust holes, and the exhaust holes are communicated with the heating or cooling medium.

[0031] The utility model has the advantages that the heating and cooling efficiency is greatly improved. Taking ordinary products as an example, the heating and cooling time of each pair of big soles is 500 seconds, and the utility model can shorten the time by more than 150 seconds. Therefore, the cost of each pair of products can be saved by more than 1.2 yuan.

[0032] The energy consumption is greatly saved. The water pouring type heating and cooling mode is conducted from the outside to the inside of the product through the whole thickness of the mold, which is time-consuming and low in efficiency.

[0033] The cooling liquid cannot enter the product cavity and cannot pollute the product and block the exhaust hole.

[0034] The working environment is improved.

[0035] The service life of the mold and the equipment is longer.

[0036] The increased heating and cooling cavities correspondingly reduce the casting cost of the mold aluminum material, and each mold can reduce about 4 kg of aluminum material, and the cost is about 200 to 300 yuan per piece.

[0037] The utility model is further described in combination with the drawings and the specific embodiments. DRAWINGS
