Description

Technical Field

[0001] The utility model relates to the technical field of molds, and more specifically to a structure in which an ejector plate is driven by an oil cylinder for a slide block. Background Art

[0002] Moulds, as core tools in the field of modern industrial manufacturing, are of self-evident importance. From automobiles, electronics to aerospace, almost every manufacturing field cannot do without the support of moulds. Mould design, manufacturing and application technology are constantly advancing with the advancement of science and technology and the development of industry, bringing unprecedented changes to industrial manufacturing. With the promotion of advanced production modes such as intelligent manufacturing and digital factories, the application of moulds has become more intelligent and efficient. In the manufacturing process of moulds, in order to meet the needs of product diversification and improve production efficiency, the design of mould opening mechanism is particularly important.

[0003] The shortcomings of the existing technology: Traditional mold opening mechanisms often have problems such as insufficient stroke and insufficient ejection force, which may cause the mold to get stuck or damaged during the mold opening process. When encountering products with too many glue positions on the side, since the mold product is large, there are too many glue positions on the slide, and the bone position is deep, the product will stick to the slider during mold opening. When the slider is withdrawn, it is necessary to ensure that the product will not follow the slider. Conventional glue position retaining walls and spring ejectors are not suitable for this product. Therefore, a structure in which the slider is driven by an oil cylinder and an ejector plate is required. Utility Model Content

[0004] In order to overcome the above defects of the prior art, the utility model provides a structure in which a slide block is driven by an oil cylinder to drive an ejector plate, so as to solve the problems existing in the above background technology.

[0005] The utility model provides the following technical scheme: a slide block uses an oil cylinder to drive an ejector plate structure, comprising a supporting base plate, a fixed block is fixedly connected to the right side of the top of the supporting base plate, an oil cylinder is fixedly installed on the right side of the fixed block, an output end of the oil cylinder passes through the fixed block and is fixedly connected to a pulling block, a top plate assembly is arranged on the left side of the pulling block, a slide block seat is arranged on the left side of the top plate assembly, a large slide block insert is fixedly connected to the left side of the slide block seat, a side debonding position insert is fixedly connected to the left side of the large slide block insert, an assembly cavity is provided inside the slide block seat, an ejection mechanism is embedded in the assembly cavity, a slide groove is provided at the bottom of the slide block seat, and a clamping groove is provided at the top of the slide groove.

[0006] Preferably, a control component is fixedly mounted on the top of the fixed block, and the control component is electrically connected to the oil cylinder.

[0007] Preferably, the top plate assembly includes a top plate shovel base, a control block, a transmission rod, a through slot and a limit block. The control block is embedded in the bottom of the top plate shovel base, a transmission rod is provided on the right side of the top of the control block, a through slot is opened on the right side of the top of the control block, and the limit block is slidably connected in the through slot.

[0012] Technical effects and advantages of the utility model:

[0013] The utility model is provided with a top plate assembly, a slider seat, a large slider insert, a side glue withdrawal position insert and an ejection mechanism that cooperate with each other. During use, the oil cylinder drives the top plate assembly to move leftward through the pull block, and then drives the slider seat, the large slider insert and the side glue withdrawal position insert to move synchronously. When the product sticks to the slider during mold opening, the ejection mechanism can eject the product in time to prevent the product from moving with the slider, thereby effectively solving the problems of insufficient stroke and insufficient ejection force existing in the traditional mold opening mechanism, and improving the mold opening efficiency and product quality of the mold. At the same time, the provision of the guide block and the wear-resistant block can increase the stability and wear resistance of the bottom plate and extend the service life of the mold. In addition, the addition of the control component makes the operation of the oil cylinder more stable and controllable, and utilizes the thrust of the oil cylinder to achieve a larger core pulling distance and a stronger ejection force, so that the mold can complete the mold opening action more stably and reliably.

[0022] The technical solution of the present invention will be clearly and completely described below in conjunction with the drawings in the present invention. In addition, the forms of the various structures recorded in the following embodiments are merely illustrative. The structure of a slider driven by an oil cylinder with an ejector plate involved in the present invention is not limited to the various structures recorded in the following embodiments. All other embodiments obtained by ordinary technicians in this field without making creative work belong to the scope of protection of the present invention.

[0023] The utility model provides a structure in which a slide block drives an ejector plate with an oil cylinder. Figure 1-7 As shown, it includes a supporting base plate 1, a fixed block 2 is fixedly connected to the right side of the top of the supporting base plate 1, a cylinder 3 is fixedly installed on the right side of the fixed block 2, the output end of the cylinder 3 passes through the fixed block 2 and is fixedly connected to a pulling block 4, a top plate assembly 5 is arranged on the left side of the pulling block 4, a slider seat 6 is arranged on the left side of the top plate assembly 5, a large slider insert 7 is fixedly connected to the left side of the slider seat 6, a side debonding insert 8 is fixedly connected to the left side of the large slider insert 7, an assembly cavity 601 is opened inside the slider seat 6, an ejection mechanism 9 is embedded in the assembly cavity 601, a slide groove 602 is opened at the bottom of the slider seat 6, and a card groove 603 is opened at the top of the slide groove 602.

[0024] Specifically, when the slider seat 6 is in the mold closing state, the limit block 505 is stuck by the slider seat 6 and the control block 502, resulting in the top plate shovel base 501 being unable to move and unable to drive the ejection mechanism 9 to move. When the slider seat 6 withdraws a specified distance, the position of the slot 603 at the bottom of the slider seat 6 is opposite to the through slot 504 of the control block 502. When the limit block 505 slides into the slot 603 after being squeezed, the top plate and the top plate shovel base 501 can be withdrawn as a whole and can move left and right. When the limit block 505 is pushed back to the position of the slot 602, due to the oblique force on the limit block 505, it is pushed into the wear-resistant block 12 by the slider seat 6 to separate them. The slider seat 6 continues to move, and the top plate and the top plate shovel base 501 are positioned to the specified position.

[0025] Furthermore, a control component 10 is fixedly installed on the top of the fixed block 2, and the control component 10 is electrically connected to the cylinder 3. First, the cylinder 3 drives the slider seat 6, the large slider insert 7, the side glue withdrawal insert 8 and the sleeve needle 9034 to retreat to the right for the first time by 40 millimeters. In the next step, the cylinder 3 drives the entire structure to retreat to the right and then retreat 145 millimeters, and the product can be taken out. Finally, the cylinder 3 drives the entire structure to move 145 millimeters to the left. After that, because the two control pins clamp the top plate assembly 5, the remaining slider seat 6 and the insert part continue to move horizontally, and the cylinder 3 is ejected into place due to the limit block 505 and enters the mold closing state.

[0026] Furthermore, the top plate assembly 5 includes a top plate shovel base 501, a control block 502, a transmission rod 503, a through groove 504 and a limit block 505. The control block 502 is embedded in the bottom of the top plate shovel base 501, and a transmission rod 503 is arranged on the right side of the top of the control block 502. A through groove 504 is opened on the right side of the top of the control block 502. The limit block 505 is slidably connected in the through groove 504. The design of the control block 502 and the limit block 505 is used to achieve precise control and stable movement of the top plate assembly 5. When the slider seat 6 withdraws a specified distance, the limit block 505 can smoothly enter the slot 603, so that the top plate shovel base 501 can move left and right, thereby driving the ejection mechanism 9 to perform the ejection operation. At the same time, when the slider seat 6 continues to move, the limit block 505 can be pushed into the wear-resistant block 12 by the slider seat 6 to achieve smooth separation, thereby ensuring the smooth operation of the entire mechanism.

[0027] Furthermore, the control block 502 is slidably connected in the slide groove 602, and the limit block 505 is adapted to the slot 603. When the slider seat 6 withdraws a specified distance, the slot 603 at the bottom of the slider seat 6 is positioned opposite to the through slot 504 of the control block 502. When the limit block 505 slides into the slot 603 after being squeezed, the top plate and the top plate shovel base 501 can be withdrawn as a whole and can move left and right. When the limit block 505 is pushed back to the position of the slide groove 602, due to the oblique force on the limit block 505, it is pushed into the wear-resistant block 12 by the slider seat 6 to separate them. The slider seat 6 continues to move, and the top plate and the top plate shovel base 501 are positioned to the specified position.

[0028] Furthermore, the ejection mechanism 9 includes an upper mounting plate 901, a lower mounting plate 902, an ejection assembly 903, a guide column 904 and a guide sleeve 905. The lower mounting plate 902 is fixedly connected to the right side of the upper mounting plate 901. The ejection assembly 903 and a plurality of guide columns 904 are arranged in the upper mounting plate 901 and the lower mounting plate 902. The guide sleeves 905 are sleeved on the outer walls of the guide columns 904. The cooperation between the guide columns 904 and the guide sleeves 905 ensures the stability and movement accuracy of the ejection mechanism 9, so that the ejection assembly 903 can accurately complete the ejection task.

[0029] Furthermore, the ejection assembly 903 includes an ejector pin 9031, an inclined ejector pin 9032, a square ejector pin 9033 and a sleeve needle 9034. There are a plurality of ejector pins 9031, inclined ejectors 9032, square ejectors 9033 and sleeve needles 9034. The ejection pressure of the ejection assembly 903 is transmitted from the upper mounting plate 901 and the lower mounting plate 902 to the ejector plate shovel base 501, and is connected by a transmission rod 503. The arrangement of these ejection assemblies 903 enables the utility model to meet the ejection requirements of different products and improves the versatility and flexibility of the equipment.

[0030] Furthermore, guide blocks 11 are fixedly connected to the front and rear sides of the support base plate 1, and wear-resistant blocks 12 are fixedly connected to the front and rear sides of the top of the support base plate 1. The guide blocks 11 are used to limit the top plate assembly 5 and the slider seat 6 so that they can slide within a specified range to avoid displacement during the demolding process.

[0031] The working principle of the utility model: when working, the oil cylinder 3 drives the top plate assembly 5 to move through the pull block 4. The movement of the top plate assembly 5 is achieved through the cooperation of the control block 502 and the limit block 505 with the slot 603 and the slide slot 602 of the slider seat 6, so as to realize precise control and stable movement. When the slider seat 6 withdraws the specified distance, the limit block 505 enters the slot 603, so that the top plate shovel base 501 can move left and right, thereby driving the ejection mechanism 9 to perform the ejection operation. The ejection mechanism 9 ensures stability and movement accuracy through the cooperation of the guide column 904 and the guide sleeve 905, so that the ejection assembly 903 can accurately complete the ejection task. At the same time, the guide block 11 and the wear-resistant block 12 of the support base plate 1 limit and support the top plate assembly 5 and the slider seat 6, ensuring the smooth operation of the entire mechanism. The control component 10 is electrically connected to the oil cylinder 3, and the motion control of the entire mechanism is achieved by controlling the extension and contraction of the oil cylinder 3, thereby achieving precise control and stable movement of the slider seat 6 and the ejection mechanism 9, improving the versatility and flexibility of the equipment, reducing production costs, and improving production efficiency.
