Description

Technical Field

[0001] This utility model relates to the technical field of rubber product processing equipment, and in particular to rubber gasket hot pressing molding equipment. Background Technology

[0002] Rubber gaskets are industrial parts widely used in sealing and other fields, and one of their main production methods is thermoforming. In traditional thermoforming processes, a hot press is typically used to heat and pressurize the rubber raw material in a mold, causing it to vulcanize and solidify. However, after thermoforming, the workpiece usually has flash and burrs on the edges, and the finished product remains in the mold. Therefore, after the molding process, subsequent trimming and removal operations are required.

[0003] Currently, most of these follow-up operations rely on manual labor or require transferring the workpieces to specialized trimming equipment for secondary processing, dividing the entire production process into multiple independent workstations. This fragmented production method not only disrupts the continuity of production and significantly reduces overall production efficiency, but also makes manual trimming and part removal labor-intensive, and the processing accuracy and quality are difficult to guarantee, easily leading to product defects.

[0004] Therefore, this utility model proposes a rubber gasket hot pressing molding equipment to overcome the shortcomings of the prior art. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a rubber gasket hot pressing molding equipment, which aims to improve the problem that existing rubber gasket hot pressing molding equipment usually only has a hot pressing function, and the subsequent edge trimming and finished product removal processes rely on manual labor, resulting in low overall production efficiency and low degree of automation.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A rubber gasket hot pressing molding equipment includes: a base, a lower template, an upper template, a first hydraulic cylinder, an edge trimming assembly, and an ejection assembly.

[0007] The trimming component is configured to move horizontally between the upper template and the lower template.

[0008] Furthermore, the trimming component is combined with the upper template and the lower template through a motional cooperation relationship in which the upper template first inserts and positions the workpiece horizontally, and then the upper template drives the vertical cutting. At the same time, the ejection component is located below the lower template and is used to eject the workpiece after the trimming is completed.

[0009] Preferably, the trimming assembly includes a trimming plate, a mounting base, a third hydraulic cylinder for driving the mounting base to move horizontally, and a trimming blade disposed on the trimming plate.

[0010] Preferably, the trimming assembly further includes a second guide post, which provides guidance and support for the horizontal movement of the mounting base.

[0011] Preferably, the ejection assembly includes a second hydraulic cylinder, an ejection plate connected to the second hydraulic cylinder, and an ejection column disposed on the ejection plate.

[0012] Preferably, the lower template has an ejection hole corresponding to the position of the ejection column.

[0013] Preferably, the rubber gasket hot pressing molding equipment further includes a mounting box, which is disposed on the base and is used to accommodate and protect the second hydraulic cylinder.

[0014] Preferably, the rubber gasket hot pressing molding equipment further includes a first guide post and an ear plate, the first guide post being vertically disposed on the base, and the ear plate being fixed to the upper template and slidingly engaged with the first guide post.

[0015] Preferably, the rubber gasket hot pressing molding equipment further includes a fixing cover, which is disposed on the top of the equipment and is used to install the hydraulic cylinder.

[0016] Preferably, the upper template is provided with a heating box inside, and the heating box is provided with a heating wire assembly.

[0017] This utility model has the following beneficial effects: 1. In this utility model, by integrating a trimming component that can move horizontally between the upper and lower templates and an ejection component that can automatically eject the workpiece, the problem of manual trimming and part removal after hot pressing in the prior art is solved, which leads to discontinuous production process and low overall efficiency. The technical effect of integrating hot pressing, trimming and ejection processes into one, realizing fully automated production, and thus significantly improving production efficiency is achieved.

[0018] 2. In this utility model, by setting up a trimming component that is driven by an independent hydraulic cylinder for translation and positioning, and then driven by the main hydraulic cylinder for vertical downward pressing, the problem of low trimming accuracy, unstable edge quality and high defect rate caused by the reliance on manual trimming of rough edges in the prior art is solved. It achieves precise, fast and automated trimming of rubber gaskets, thereby ensuring smooth edges and consistent dimensions of finished products, and significantly improving the product qualification rate.

[0019] 3. In this utility model, by setting independent first and second guide columns for the lifting movement of the upper template and the horizontal movement of the trimming component, the problem of inaccurate positioning and unstable movement during the pressing and cutting process that may be caused by a single or no guide structure is solved, thereby affecting product quality and equipment reliability. The overall structure is stable and the movement of key components is precise and reliable, thus ensuring the long-term stable operation of the equipment and the consistency of product quality.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example: Please refer to Figures 1-6This utility model provides a rubber gasket hot pressing molding equipment, which aims to solve the problems of existing hot pressing equipment having single function and lacking integrated trimming and ejection structures, resulting in low automation and low production efficiency.

[0024] like Figure 1 As shown, the rubber gasket hot pressing molding equipment includes a base 1, which serves as the mounting base for the entire equipment and provides stable support for other components. The lower template 5 is set on the base 1, and the first guide post 3 is vertically set on the base 1. The upper template 6 is movably positioned above the lower template 5. The ear plate 4 is fixed to the upper template 6, and the ear plate 4 and the first guide post 3 form a sliding connection, thereby providing stable guidance for the lifting and lowering movement of the upper template 6. The fixed cover 8 is set on the top of the equipment. The first hydraulic cylinder 7 is installed through the fixed cover 8 and is connected to the upper template 6 to drive the upper template 6 to lift and lower relative to the lower template 5. A heating box 11 is set inside the upper template 6, and a heating wire group 12 is further set inside the heating box 11 to heat the upper template 6.

[0025] To solve the above-mentioned technical problems, the core of the technical solution of this embodiment is that the rubber gasket hot pressing molding equipment also includes an edge trimming component 10, and the edge trimming component 10 forms a specific structural fit and movement relationship with the upper template 6 and the lower template 5.

[0026] Please refer to the following carefully. Figure 1 The core structure will be described in detail below: The trimming assembly 10 includes a mounting base 1002, a trimming plate 1001 fixedly connected to the mounting base 1002, and a trimming blade 1005 mounted on the trimming plate 1001. The output end of a third hydraulic cylinder 1003 is fixedly connected to the mounting base 1002 and is used to drive the mounting base 1002 to perform horizontal reciprocating motion. The trimming assembly 10 also includes a second guide post 1004, which provides precise guidance and stable support for the horizontal movement of the mounting base 1002. During operation, the trimming assembly 10 is configured such that after the first hydraulic cylinder 7 drives the upper template 6 to complete heat pressing and lift, the third hydraulic cylinder 1003... Driven by 003, the mounting base 1002 moves horizontally along the direction of the second guide post 1004 until the trimming blade 1005 enters the predetermined cutting position between the upper template 6 and the lower template 5. At this time, the first hydraulic cylinder 7 is activated again, driving the upper template 6 and the trimming assembly 10 below it to move downward as a whole. The trimming blade 1005 performs precise trimming on the workpiece on the lower template 5. This structure and method of first horizontally inserting and positioning and then vertically pressing and cutting ensures the automated execution of the trimming action, effectively avoids defects that may be caused by manual trimming, and significantly improves the dimensional accuracy and edge quality of the rubber gasket.

[0027] Based on the above embodiments, the present invention may further include the following preferred technical solutions: In a preferred embodiment, the rubber gasket hot pressing molding equipment further includes an ejector assembly 9 disposed below the lower template 5. The ejector assembly 9 is used to automatically eject the molded workpiece from the lower template 5 after all trimming operations are completed. Specifically, the ejector assembly 9 includes a second hydraulic cylinder 901, an ejector plate 902, and an ejector column 903. The output end of the second hydraulic cylinder 901 is fixedly connected to the lower surface of the ejector plate 902, and the ejector column 903 is vertically arranged on the upper surface of the ejector plate 902. In order to cooperate with the action of the ejector assembly 9, the lower template 5 is provided with ejector holes 904 corresponding to the position of each ejector column 903. Under the drive of the second hydraulic cylinder 901, the ejector column 903 can drive the ejector plate 902 to move upward and accurately pass through the ejector hole 904.

[0028] As another preferred embodiment, in order to effectively install and fully protect the second hydraulic cylinder 901, the equipment also includes a mounting box 2 set on the base 1. The second hydraulic cylinder 901 and the ejector plate 902 and other components are all housed inside the mounting box 2. Through the structure of the mounting box 2, external debris can be prevented from interfering with or damaging the precision components of the second hydraulic cylinder 901, thus ensuring the long-term stability of the ejector assembly 9.

[0029] Working principle: First, the rubber raw material is placed on the lower mold plate 5. The first hydraulic cylinder 7 is activated to drive the upper mold plate 6 to move smoothly downward under the guidance of the first guide post 3 and the ear plate 4, pressing it against the lower mold plate 5. At the same time, the heating wire group 12 inside the heating box 11 is activated to heat the upper mold plate 6, thereby completing the hot pressing molding operation of the raw material. After the hot pressing is completed, the first hydraulic cylinder 7 lifts the upper mold plate 6, and then the third hydraulic cylinder 1003 is activated. The third hydraulic cylinder 1003 drives the mounting base 1002 to move horizontally along the second guide post 1004, sending the trimming plate 1001 with the trimming blade 1005 into the space that has been separated between the upper mold plate 6 and the lower mold plate 5. Then the first hydraulic cylinder 7 drives the upper mold plate 6 to press down again, trimming the edges. The blade 1005 precisely trims the edges of the formed workpiece. After the trimming operation is completed, the first hydraulic cylinder 7 lifts the upper template 6 again, and the third hydraulic cylinder 1003 pulls the trimming assembly 10 back to the initial position. Then, the second hydraulic cylinder 901 in the mounting box 2 is activated. The second hydraulic cylinder 901 pushes the ejector plate 902 upward, so that the ejector column 903 on the ejector plate 902 passes through the ejector hole 904 of the lower template 5, and automatically ejects the processed rubber gasket workpiece from the lower template 5. Through the synergistic action of the trimming assembly 10 and the ejector assembly 9, this utility model integrates hot pressing, automatic trimming and automatic ejection processes into one, solving the problem of low production efficiency and unstable product precision caused by the reliance on manual post-processing in the prior art.

[0030] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
