Description

TECHNICAL FIELD

[0001] The utility model relates to a shoe sole mould technical field especially relates to a take out convenient shoe sole mould. BACKGROUND

[0002] At present, mountaineering shoes are shoes specially designed and manufactured for mountain climbing and travel, which are very suitable for outdoor sports. Waterproofness is the primary function of modern mountaineering shoes, and its waterproof and breathable performance cannot be compared with ordinary sports shoes. In the production field of shoe soles, shoe soles are generally produced by pressing. In the shoe sole production process in the prior art, the shoe sole mould generally comprises an upper die plate and a lower die plate which can be buckled with the upper die plate. A punch is arranged on the upper die plate, and a recessed die which cooperates with the punch to form a shoe sole mould structure is arranged on the lower die plate. After the shoe sole is pressed and formed, the shoe sole, the upper and the inner surrounding strip are connected and shaped. The finished shoe sole is easily tightly combined with the shoe sole mould, making it difficult for the user to demould the shoe sole, and the demoulded shoe sole is easily damaged.

[0003] For example, a kind of take out convenient shoe sole mould (announcement number: CN219806387U) is disclosed in Chinese patent document. This patent uses an electric push rod to move the lifting plate upwards, which drives the ejector pin and the ejector rod to move upwards, thereby ejecting the product in the shoe sole shaping cavity. Workers do not need to use special auxiliary tools to manually disconnect the finished product from the shoe sole shaping cavity, which facilitates workers to take out the finished product, thereby facilitating demoulding and material taking. The maintenance door is opened to maintain and clean the internal parts of the shoe sole lower mould, thereby facilitating maintenance during use of the shoe sole mould.

[0004] However, when the ejector pin and the ejector rod are used to eject the shoe sole, the parts of the ejector pin and the ejector rod in contact with the shoe sole will inevitably leave marks on the surface of the shoe sole due to the instantaneous high pressure, which reduces the appearance of the product. Moreover, for some shoe sole products with complex shape, deep hole, reverse buckle or thin wall structure, such as professional mountaineering shoe soles, in order to enhance the grip and drainage performance, the shoe sole is designed with deep texture grooves. The bottom space of these grooves is narrow, and the ejector pin cannot accurately penetrate deep. Even if it is forced out, it is also easy to cause tearing and deformation of the shoe sole near the deep hole due to uneven stress, resulting in damage to the function of the shoe sole. INVENTION CONTENTS

[0005] The utility model aims at solving the problems existing in the prior art, such as uneven stress leading to damage to the function of the shoe sole when the ejector pin and the ejector rod are used to demould the mountaineering shoe sole.

[0006] In order to achieve the above-mentioned purpose, the utility model adopts the following technical solutions:

[0007] A convenient material-receiving shoe sole mold includes a lower mold, a shaping groove at the upper end of the lower mold, an installation cavity inside the lower mold, and through holes arranged in a linear array on the inner top wall of the installation cavity.

An air blowing mechanism is provided inside the installation cavity, and the air blowing mechanism includes a lifting block. The outer side of the lifting block is movably sleeved with the inner wall of the installation cavity.

[0008] The upper end of the lifting block is fixedly connected to a blocking rod arranged in a linear array, and an annular stop block is fixedly sleeved on the outside of the blocking rod. The upper end of the annular stop block contacts the inner top wall of the mounting cavity.

[0009] Preferably, the inner bottom wall of the mounting cavity is fixedly connected to a guide sleeve arranged in a linear array, and the inner wall of the guide sleeve is movably fitted with a telescopic rod, the upper ends of the multiple telescopic rods being fixedly connected to the lower end of the lifting block.

[0010] Preferably, a support spring is movably sleeved on the outside of the guide sleeve, one end of the support spring is fixedly connected to the inner bottom wall of the mounting cavity, and the other end of the support spring is fixedly connected to the lower end of the lifting block.

[0011] Preferably, an air inlet pipe is fixedly connected to one side of the inner wall of the mounting cavity, one end of the air inlet pipe passes through and extends to one side of the lower mold, and a pressure regulating valve is provided on the outside of the air inlet pipe.

[0012] Preferably, the lower end of the lower mold is fixedly connected to a fixed base, and the upper end of the fixed base is fixedly mounted with symmetrically distributed servo electric cylinders.

[0013] Preferably, one end of each of the two servo electric cylinder piston rods is fixedly connected to a top plate, and an upper mold is provided at the lower end of the top plate.

[0014] Preferably, the upper end of the plug rod is movably inserted into the inner wall of the through hole, and the upper end of the plug rod is at the same level as the inner bottom wall of the shaping groove.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] In this invention, the air blowing mechanism achieves the effect of blowing compressed air into the installation cavity, thereby causing the air pressure to drive the blocking rod to descend and move away from the through hole through the lifting block. Then, the compressed air quickly fills the gap between the cavity and the sole, forming a uniform air cushion, which effectively lifts the sole and assists in demolding. Moreover, the air will not pollute or damage the sole material, nor will it react chemically with the sole, thus ensuring the quality of sole demolding. Attached Figure Description

[0027] Example

[0028] like Figures 1-5 As shown, this utility model provides a technical solution: a shoe sole mold with convenient material handling, including a lower mold 1. The lower mold 1 is made of high-strength, wear-resistant, and thermally stable alloy steel. Its upper end is carefully provided with a shaping groove 2 for shaping the shoe sole. The inner wall of the shaping groove 2 is finely ground and polished to ensure a smooth surface on the molded shoe sole, reducing subsequent processing steps. The lower mold 1 cleverly incorporates an installation cavity 3. The design and layout of the installation cavity 3 fully considers the installation and operation requirements of subsequent components, providing a stable environment for the entire air-blowing demolding mechanism. The mounting cavity 3 has a linear array of through holes 4 on its inner top wall, which are machined with high precision. One end of the through holes 4 is connected to the inner bottom wall of the shaping groove 2. This connection structure provides a key channel for compressed air to enter the shaping groove 2 to assist in demolding. The mounting cavity 3 is equipped with an air blowing mechanism, which includes a lifting block 5. The lifting block 5 is also made of high-quality steel that is compatible with the lower mold 1. Its exterior is fitted with the inner wall of the mounting cavity 3 with a very small tolerance, which can ensure that the lifting block 5 moves smoothly under air pressure and prevent gas leakage.

[0029] The upper end of the lifting block 5 is fixedly connected with a linear array of plug rods 51 by a strong welding process. The material of the plug rods 51 has a certain rigidity and wear resistance, ensuring that they are not easily deformed or worn during frequent insertion and removal. An annular stop block 52 is fixedly sleeved on the outside of the plug rods 51. The annular stop block 52 adopts a thickened design, and its upper end is in close contact with the inner top wall of the installation cavity 3. It can not only play a good limiting role for the plug rods 51 and prevent them from rising excessively, but also assist in sealing to a certain extent and prevent gas from leaking from the through hole 4.

[0030] The inner bottom wall of the mounting cavity 3 is fixedly connected with guide sleeves 53 arranged in a linear array. The inside of the guide sleeves 53 is finely bored and smooth, providing a near-frictionless environment for the movement of the telescopic rods 54. The telescopic rods 54 are precisely fitted onto the inner wall of the guide sleeves 53. The fit between the telescopic rods 54 and the guide sleeves 53 is extremely precise. The upper ends of multiple telescopic rods 54 are all fixedly connected to the lower end of the lifting block 5 through a reliable connection method. The two work together to provide stable and precise guidance for the up and down movement of the lifting block 5.

[0031] A support spring 55 is movably sleeved on the outside of the guide sleeve 53. The support spring 55 is made of high-quality spring steel with a suitable elastic coefficient and undergoes a strict heat treatment process to ensure its elasticity is stable and durable. One end of the support spring 55 is fixedly connected to the inner bottom wall of the mounting cavity 3 by welding or riveting. The other end of the support spring 55 is fixedly connected to the lower end of the lifting block 5 by the same reliable connection method. In the entire mold operation process, the support spring 55 plays a key role. Initially, it provides support force for the lifting block 5, keeping the blocking rod 51 in the position of closing the through hole 4. After demolding, it helps the lifting block 5 to reset.

[0032] An air inlet pipe 56 is fixedly connected to one side of the inner wall of the mounting cavity 3 by a precision welding process. The air inlet pipe 56 is made of high-pressure resistant and corrosion-resistant tubing. One end of the pipe passes through and extends to one side of the lower mold 1, and the outlet is properly sealed to prevent gas leakage. A pressure regulating valve 57 is installed on the outside of the air inlet pipe 56. The pressure regulating valve 57 adopts advanced CNC adjustment technology, which can accurately set the air inlet pressure according to key factors such as the characteristics of different shoe sole materials and the complexity of the mold structure, ensuring that the blowing operation can efficiently assist demolding without causing any damage to the shoe sole.

[0033] The lower end of the lower mold 1 is fixedly connected to a fixed base 6 by bolts. The fixed base 6 is made of heavy cast iron, which has excellent stability and shock resistance, and provides a solid support foundation for the entire mold. The upper end of the fixed base 6 is fixedly installed with symmetrically distributed servo electric cylinders 7 through professional installation process. The servo electric cylinders 7 have high-precision position control and powerful driving force, which can accurately control the lifting and lowering of the top plate 8.

[0034] One end of each piston rod of the two servo electric cylinders 7 is fixedly connected to a top plate 8. The top plate 8 is made of high-strength aluminum alloy, which reduces the overall weight while ensuring strength and facilitates lifting and lowering operations. The lower end of the top plate 8 is provided with an upper mold 9. The upper mold 9 and the lower mold 1 are compatible in structure and material. The two are combined to form a complete shoe sole mold cavity. The surface of the upper mold 9 is also finely treated to ensure the quality of shoe sole molding.

[0035] The upper outer end of the plug rod 51 is movably inserted into the inner wall of the through hole 4 with a very small tolerance. This tight fit can effectively seal the through hole 4 and can also be easily disengaged when needed. The upper end of the plug rod 51 is at the same level as the inner bottom wall of the shaping groove 2, ensuring that the bottom surface of the shaping groove 2 is flat during the sole forming process and that the presence of the plug rod 51 will not affect the forming quality of the sole.

[0036] The working process of this utility model:

[0037] Step 1: In the initial state, the lifting block 5 is in a higher position under the elastic force of the support spring 55, and the upper end of the blocking rod 51 is at the same level as the inner bottom wall of the shaping groove 2. At this time, the blocking rod 51 closes the through hole 4, and the shaping groove 2 of the lower mold 1 is ready to cooperate with the upper mold 9. The two servo electric cylinders 7 are started, and their piston rods retract, pulling the top plate 8 downward. The top plate 8 drives the upper mold 9 to move downward in sync until the upper mold 9 and the shaping groove 2 of the lower mold 1 are tightly engaged. The two together form a complete shoe sole mold cavity. Then, the liquid shoe sole raw material is injected into the mold cavity. Under the process requirements of pressure holding and cooling, after a certain period of time, the shoe sole is initially formed in the mold.

[0038] Step two: When the sole is formed and demolding is required, an external compressed air source supplies gas to the mounting cavity 3 through the air inlet pipe 56. The pressure regulating valve 57 on the air inlet pipe 56 has been pre-set with a precise air inlet pressure based on key factors such as the sole material and mold structure. This is to ensure that the subsequent blowing operation can achieve effective demolding without causing any damage to the sole. As compressed air is continuously injected into the mounting cavity 3, the air pressure inside the cavity steadily increases. Because the air pressure acts evenly on the upper surface of the lifting block 5, When the downward thrust generated by the air pressure successfully exceeds the elastic force of the support spring 55, the lifting block 5 starts to move downward. The blocking rod 51, which is fixed to the lifting block 5, and the annular stop block 52 on the blocking rod 51 move downward simultaneously. The blocking rod 51 gradually disengages from the through hole 4, opening up the airflow channel between the installation cavity 3 and the shaping groove 2. Compressed air rushes into the shaping groove 2 through the through hole 4 and spreads rapidly in the extremely fine gap between the sole and the inner wall of the shaping groove 2. In an instant, it fills the entire gap and steadily lifts the sole.

[0039] Step three: During the process, the guide sleeve 53, in conjunction with the telescopic rod 54, plays a stabilizing and guiding role in the descent of the lifting block 5. After demolding is completed, the gas supply from the air inlet pipe 56 is stopped. At this time, the elastic force of the support spring 55, through the cooperation of the guide sleeve 53 and the telescopic rod 54, drives the lifting block 5 to reset and move upward, so that its blocking rod 51 continues to be inserted into the through hole 4 for sealing. The annular stop block 52 effectively limits the insertion depth of the blocking rod 51, waiting for the next demolding.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
