Description

Technical Field

[0001] The present application relates to the technical field of rubber part processing equipment, and in particular to a rubber part correction tool. Background Art

[0002] In the automotive parts manufacturing industry, rubber parts, as key components, are widely used for various functions such as shock absorption, sealing, and thermal insulation, and are crucial to vehicle performance and safety. With the development of the automotive industry, the requirements for the quality and precision of rubber parts are becoming increasingly stringent. High-quality production of rubber parts not only improves vehicle safety and comfort, but also significantly reduces maintenance costs and enhances market competitiveness. The rubber part production process typically includes mold forming and subsequent vulcanization, which has a decisive impact on the final performance of the rubber part.

[0003] However, during the molding and vulcanization process, rubber parts often encounter shrinkage issues. This shrinkage phenomenon is an inherent characteristic of rubber materials and usually occurs after molding. It can cause the size of the rubber part to decrease, exceeding the standard requirements, thus affecting its performance and safety.

[0004] Manufacturers often need to implement additional post-processing measures, such as manual trimming or the use of complex calibration equipment. While manual trimming is simple, it is inefficient, prone to human error, and difficult to ensure consistent product quality. While using complex calibration equipment can improve accuracy and efficiency, it is expensive, complex, and sometimes difficult to guarantee the quality of the calibrated product. Utility Model Content

[0005] In order to improve the problem that rubber parts usually shrink after molding, resulting in size reduction, subsequent processing steps are cumbersome and production costs are increased, the present application provides a rubber part correction tool.

[0006] This application provides a rubber part correction tool, which adopts the following technical solution:

[0007] A rubber part correction tool comprises: a connecting plate and a positioning assembly, wherein the positioning assembly is arranged on the connecting plate;

[0008] The positioning assembly includes a positioning protrusion and a stopper; the positioning protrusion and the stopper are both connected to the connecting plate, and the stopper is provided in multiple groups, which are arranged along the periphery of the connecting plate and form a positioning cavity for accommodating the rubber member. There are multiple positioning protrusions, and they are also arranged along the periphery of the connecting plate. The positioning protrusions are arranged in a one-to-one correspondence with the holes on the rubber member, and the positioning protrusions are located in the positioning cavity formed by the stopper.

[0009] By employing the above technical solution, the rubber part calibration tool effectively addresses dimensional deviations caused by shrinkage after molding. The positioning assembly design allows for relatively accurate positioning and fixation of rubber parts after molding, ensuring they maintain the desired size and shape during the cooling process, thus meeting standards. Furthermore, the alignment of the positioning bumps with the holes in the rubber part further enhances positioning accuracy, ensuring stability and accuracy during the calibration process. This eliminates the need for additional subsequent processing steps and further improves work efficiency.

[0010] Preferably, the connecting plate is rectangular, and the four corners of the connecting plate are rounded.

[0011] By adopting the above technical solution, the connecting plate is designed to be rectangular and the four corners are rounded, which can effectively avoid scratches and damage caused by sharp edges during transportation and use, thereby improving the safety and service life of the tooling.

[0012] Preferably, the connecting plate is an iron plate, and the thickness of the connecting plate is 1 mm.

[0013] By adopting this technical solution, the connecting plate is made of iron and maintained at a thickness of 1 mm, which gives the tool sufficient strength and stability while reducing the overall weight of the tool, making it easier to carry and operate. This not only ensures the tool's durability and reliability, but also reduces manufacturing costs and improves production efficiency.

[0014] Preferably, a plurality of communication holes are evenly distributed around the connection plate, each communication hole is circular, and the arrangement of the communication holes matches the shape of the positioning cavity.

[0015] By adopting this technical solution, the evenly distributed connecting holes around the connecting plate further accelerate the cooling of the rubber parts, thereby avoiding calibration errors caused by positional offsets. Furthermore, the circular design of the connecting holes helps reduce stress concentration, improving the durability and reliability of the tooling.

[0016] Preferably, a plurality of connection holes are provided on the connection plate, each of the connection holes is rectangular in shape, and is arranged around the circumference of the positioning cavity.

[0017] By adopting the above technical solutions, the design effectively reduces the overall weight of the tooling, making it easier to carry and operate. Furthermore, the presence of the connecting holes reduces material usage and lowers manufacturing costs. Furthermore, the rational layout of the connecting holes does not affect the stability and reliability of the positioning cavity, ensuring the accuracy and consistency of the rubber parts during calibration.

[0018] Preferably, the stop block and the positioning protrusion are both connected to the connecting plate through rivets.

[0019] By adopting this technical solution, the rubber part calibration fixture ensures that the stopper and positioning bump are securely and reliably mounted on the connecting plate, preventing loosening or falling off during long-term use. Furthermore, the rivet connection method is simple and quick, facilitating production and maintenance, while effectively transmitting force and ensuring the stability and precision of the rubber part during calibration.

[0020] The stopper and the positioning protrusion are both made of solid wood, and the stopper is in a curved arc shape so as to match the shape of the rubber piece.

[0021] By adopting this technical solution, both the block and the positioning protrusion are made of solid wood, and the block's curved shape increases the contact area between the rubber component and the block, improving positioning accuracy and reducing displacement of the rubber component during cooling, ensuring that the rubber component accurately meets the standard after cooling. Furthermore, solid wood has excellent wear and corrosion resistance, extending the tooling's service life and reducing maintenance costs.

[0022] Preferably, a silicone grease layer is fixed on a side of the stopper close to the rubber piece and an outer side of the positioning protrusion.

[0023] By adopting this technical solution, a layer of silicone grease is fixed to the side of the block closest to the rubber part and the outer side of the positioning protrusion 21. This significantly reduces friction between the rubber part and the tooling during placement and removal, preventing scratches or damage to the rubber part's surface, thereby improving the product's appearance quality and service life. Furthermore, the silicone grease layer has excellent anti-slip properties, helping to ensure the stability and accurate positioning of the rubber part within the tooling, further enhancing the correction effect.

[0024] In summary, this application includes at least one of the following beneficial technical effects:

[0025] 1. By placing the rubber part in the positioning cavity formed by the stopper of the calibration fixture and using the one-to-one correspondence between the positioning protrusions and the holes on the rubber part, the rubber part is ensured to maintain the correct size and position during the cooling process, thus effectively solving the problem of dimensional deviation caused by shrinkage of the rubber part and ensuring that the rubber part meets the standard;

[0026] 2. The connecting plate is made of 1mm thick iron plate, which is light and inexpensive to manufacture, making it easy to carry and use. It also reduces the production and maintenance costs of the calibration tooling.

[0027] 3. The stopper and positioning protrusion are connected to the connecting plate by rivets. The structure is stable and reliable, and the operation is simple. There is no need for complicated installation steps, which further improves the practicality and convenience of the tooling. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following is combined with Figure 1-3 This application is described in further detail.

[0033] Example:

[0034] An embodiment of the present application provides a rubber part correction tool.

[0035] refer to Figure 1 The rubber part correction tooling includes a connecting plate 1 and a positioning assembly 2, wherein the connecting plate 1 is rectangular and the four corners of the connecting plate 1 are rounded, which can reduce stress concentration, extend the service life of the correction tooling, and reduce injuries to operators during transportation. The connecting plate 1 can be made of different materials, such as iron plate or other metal materials, to adapt to different usage environments and needs. In this embodiment, iron plate is selected as the material of the connecting plate 1 with a thickness of 1 mm, which not only ensures sufficient strength and rigidity, but also reduces the weight of the tooling, making it easy to carry and use.

[0036] refer to Figure 1 and Figure 2 The positioning assembly 2 includes a positioning protrusion 21 and a stopper 22, wherein the stopper 22 is provided in multiple groups, and the multiple groups of stoppers 22 are arranged along the periphery of the connecting plate 1. The multiple groups of stoppers 22 together form a positioning cavity 23 for accommodating the rubber member. The number of positioning protrusions 21 is also multiple, and they are also arranged along the periphery of the connecting plate 1. The positioning protrusions 21 are arranged one-to-one with the holes on the rubber member, and the positioning protrusions 21 are located in the positioning cavity 23 formed by the stoppers 22.

[0037] When the molded rubber part is placed in the positioning cavity 23 formed by multiple groups of stoppers 22, the positioning protrusion 21 will be inserted into the hole of the rubber part, further fixing the position of the rubber part, effectively reducing the displacement of the rubber part during the cooling process, thereby ensuring that the rubber part can be cooled and solidified according to the predetermined shape and size to meet the required standards and requirements, reducing the deformation of the rubber part, and improving the product qualification rate.

[0038] Among them, the stop block 22 and the positioning protrusion 21 are connected to the connecting plate 1 through rivets, which makes the installation of the correction tool more convenient and quick, and the connection between the stop block 22 and the positioning protrusion 21 and the connecting plate 1 is also more firm and reliable.

[0039] The stopper 22 and the positioning protrusion 21 are both made of solid wood, which is relatively light, reducing the weight of the correction tooling and facilitating transportation. At the same time, they also have good wear resistance and corrosion resistance, extending the service life of the tooling and reducing maintenance costs. The stopper 22 is a curved arc that matches the shape of the rubber part, which can increase the contact area between the rubber part and the stopper 22, improve positioning accuracy, further reduce the displacement of the rubber part during the cooling process, and further ensure that the rubber part can meet the standards after cooling and meet production requirements.

[0040] Furthermore, a silicone grease layer 3 is secured to the side of the stopper 22 closest to the rubber component and to the outer side of the positioning projection 21. The thickness and material of the silicone grease layer 3 can be selected based on actual needs to achieve optimal performance. The silicone grease layer 3 further reduces friction between the rubber component and the tooling during placement and removal, reducing the risk of scratches or damage to the rubber component's surface, thereby improving the product's appearance and service life. Furthermore, the silicone grease layer 3 offers excellent anti-slip properties, helping to ensure the stability and accurate positioning of the rubber component within the tooling, further enhancing the correction effect.

[0041] After molding, the rubber part is placed into the positioning cavity 23 of the calibration fixture. The positioning protrusion 21 and the stopper 22 work together to secure it in the correct position. The rubber part gradually shrinks during cooling, but because it is already secured in the fixture, it does not experience significant dimensional changes. After molding and cooling, the rubber part remains within tolerances and meets production requirements.

[0042] refer to Figure 1 and Figure 3 Connecting plate 1 is provided with a plurality of evenly distributed, circular communication holes 4 around its periphery. Their arrangement matches the shape of positioning cavity 23, providing airflow channels during the rubber component cooling process, accelerating heat dissipation and thus speeding up cooling and shortening processing time. The size and number of communication holes 4 can be designed based on actual heat dissipation requirements to achieve optimal cooling.

[0043] The connecting plate 1 is provided with a plurality of connecting holes 5, which can be rectangular in shape and arranged around the circumference of the positioning cavity 23. The connecting holes 5 can reduce the amount of material used, thereby effectively reducing the overall weight of the tooling, facilitating handling and operation, and further reducing manufacturing costs.

[0044] Two through holes 6 are symmetrically provided longitudinally along the middle of the connecting plate 1, and two groups of through holes 7 are also symmetrically provided laterally along the middle of the connecting plate 1. The shapes of the through holes 6 and the through holes 7 are both rectangular. The lengths of the through holes 6, the through holes 7 and the connecting holes 5 are arranged in order from small to large, which reduces the weight of the rubber part correction tooling to a certain extent.

[0045] The implementation principle of a rubber part correction tool in the embodiment of the present application is as follows:

[0046] After the rubber part is placed in the positioning cavity 23 formed by multiple groups of blocks 22 on the rubber part correction tooling, the positioning protrusions 21 corresponding to the rubber part holes can fix the position of the rubber part, effectively reducing deformation caused by cooling shrinkage. The application of solid wood material and silicone grease layer 3 of the blocks 22 and the positioning protrusions 21 further enhances the durability of the tooling and protects the surface of the rubber part. At the same time, the curved arc design of the blocks 22 further increases the contact area with the rubber part and improves the positioning accuracy. The rubber part correction tooling ensures that the rubber part maintains a predetermined shape and size during the cooling and curing process. The whole process is simple and fast, without the need for complicated post-processing measures, which greatly reduces production costs, meets production standards, and improves product qualification rate.

[0047] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
