Description

Technical Field

[0001] The utility model belongs to the technical field of sand core processing, and in particular relates to a refractory sealing pad installation device. Background Art

[0002] Sand casting is a production method in which molten metal is poured into the cavity of the mold and the product is obtained after cooling and solidification. In the process of automobile manufacturing, many parts are made of cast iron, accounting for about 60% of the weight of the whole vehicle, such as cylinder block, transmission housing, steering housing, rear axle housing, brake drum, various brackets, etc. Sand molds are usually used to manufacture cast iron parts. The raw material of the sand mold is mainly sand, which is mixed with binders, water, etc. The sand mold material must have a certain bonding strength so that it can be molded into the required shape and can withstand the erosion of high-temperature molten iron without collapse. In order to avoid the defect of pores in the casting, refractory sealing pads designed according to the shape of the sand core are generally used in the casting process to hinder the flow of molten iron, thereby forming an exhaust channel to avoid the contact between the sand core and the molten iron in the casting, resulting in the defect of sand sticking in the casting.

[0003] In the prior art, the refractory sealing gasket is generally pressed onto a designated refractory sealing gasket installation station on the sand core by manual operation. There are many unfavorable human factors in the process, resulting in the installation accuracy and flatness of the refractory sealing gasket to be improved. Utility Model Content

[0004] The utility model provides a fire-resistant sealing pad installation device to solve at least one of the above technical problems.

[0005] The technical solution adopted by the utility model is:

[0006] A fire-resistant sealing gasket installation device, comprising an outer shell, a sliding cavity is provided in the outer shell, a sliding part is slidably connected in the sliding cavity, a sealing member for sealing the sliding cavity is provided at the end of the outer shell, a plurality of holes communicating with the sliding cavity are provided on the sealing member, a plurality of groups of spikes matching with the holes are provided on one side of the sliding member close to the sealing member, the sliding member slides along the sliding cavity so that the spikes have a first position penetrating the holes and a second position located in the sliding cavity;

[0007] The invention also includes a driving portion for driving the sliding portion to slide between the first position and the second position.

[0008] Preferably, at least three holes are provided, and the three holes are arranged at equal intervals along the circumference of the seal, and the number and arrangement of the spike portions match the holes.

[0009] Preferably, the sealing member comprises a cover plate, and the cover plate is detachably connected to the end of the outer shell.

[0010] Preferably, a spring is fixedly connected between the sliding portion and the sliding cavity.

[0011] Preferably, the driving part includes a driving rod, which passes through the sliding cavity from an end away from the seal, and the end of the driving rod located in the sliding cavity is fixedly connected to the sliding part, and the end of the driving rod located outside the sliding cavity has an extension portion extending outside the outer shell.

[0012] Preferably, a push-pull handle is fixedly connected to the end of the extension portion.

[0013] Preferably, a threaded connecting rod is provided at one end of the spike portion away from the tip, and a plurality of threaded connecting grooves cooperating with the connecting rod are provided at one side of the sliding portion close to the sealing element.

[0014] Preferably, a thread groove is provided at one end of the sliding portion away from the spike portion, and an external thread matching with the thread groove is provided at one end of the driving rod located in the sliding cavity.

[0015] Preferably, the sliding portion is a circular slider, a side wall of the circular slider is provided with a limiting flange, and a limiting guide groove cooperating with the limiting flange is provided in the sliding cavity.

[0016] Preferably, the side wall of the circular slider is provided with an air guide groove.

[0017] Due to the adoption of the above technical solution, the beneficial effects achieved by the utility model are as follows:

[0018] 1. In the present application, the driving part drives the sliding part to slide from the second position to the first position, at which time the tip of the spike part penetrates through the hole and inserts into the surface of the refractory sealing pad through the spike part to grab the refractory sealing pad to be installed. Then, the staff aligns the grabbed refractory sealing pad with the installation position of the refractory sealing pad on the sand core, and applies pressure perpendicular to the refractory sealing pad of the sand core to the outer shell, so that the refractory sealing pad is stably attached to the sand core under the pressure of the seal and the bonding effect of the water-based coating. When the refractory sealing pad and the sand core are attached, the driving part drives the sliding part to slide from the first position to the second position to separate the spike part from the refractory sealing pad, and then cancels the thrust applied to the outer shell, and finally separates the seal from the refractory sealing pad to complete the installation of a single refractory sealing pad.

[0019] It is worth mentioning that when the refractory sealing gasket to be installed is grabbed by the spiked portion, the seal can keep the refractory sealing gasket flat during the process of grabbing and transporting the refractory sealing gasket, thereby avoiding wrinkles on the refractory sealing gasket that affect installation.

[0020] By utilizing the liquid adhesion of water-based paint and refractory gasket, the refractory gasket is fixed and adhered to the designated position of the sand core, eliminating the use of adhesive, reducing the gas source of the casting, and alleviating the tendency of the casting to have pores. The refractory gasket is grasped, transported and installed by the spike part and the seal contacting the refractory gasket, which can avoid contact between other parts except the refractory gasket and the water-based paint layer on the surface of the sand core, thereby avoiding damage to the paint layer caused by contact with the paint and affecting the quality of the inner cavity of the casting.

[0021] 2. As a preferred embodiment of the present invention, the provision of at least three holes and spikes is conducive to increasing the stability during the process of grabbing and transporting the refractory sealing pad, such as Figure 3 As shown, there are four holes and spikes, and the four spikes can provide three grabbing points when grabbing the refractory sealing gasket, which is also beneficial to ensure that the refractory sealing gasket is always in a flat posture during transportation.

[0022] 3. As a preferred embodiment of the present invention, the cover plate is a circular groove structure, the inner wall of the circular groove is provided with an internal thread, and the outer end of the shell is provided with an external thread that matches the internal thread, and the cover plate is installed, removed, and replaced by matching the internal thread with the external thread. Cover plates with various hole arrangement patterns and sliding parts with various spike arrangement patterns can be designed to adapt to various shapes of refractory gaskets, and the cover plate and sliding part can be replaced by disassembling them.

[0023] 4. As a preferred embodiment of the utility model, when the sliding part slides from the second position to the first position, the spring is compressed and deformed, and the kinetic energy is converted into elastic potential energy. When the thrust applied to the driving part is removed, the elastic potential energy of the spring is released, and the sliding part is reset from the first position to the second position, thereby achieving the effect of saving manpower.

[0024] 5. As a preferred embodiment of the utility model, when the sliding part needs to be driven to move from the second position to the first position, the staff can push the driving rod by applying a thrust to the end of the extension part with the palm of their hand to push the sliding part from the second position to the first position. After the thrust applied to the extension part is withdrawn, the spring resets and pulls the sliding part to slide from the first position to the second position. The operation is easy and convenient to use. The setting of the push-pull handle makes it easier for the staff to push and pull the driving rod.

[0025] 6. As a preferred embodiment of the utility model, the threaded connecting rod and the threaded connecting groove are arranged to facilitate the disassembly of the spike part, and the spike with damaged tip does not need to be replaced. At the same time, the spike part can be adaptively installed on the sliding part according to the shape of the refractory sealing gasket.

[0026] The sliding part and the driving rod cooperate with each other through the thread groove and the external thread, so that the sliding part and the driving rod are detachably connected, so as to facilitate the replacement and maintenance of the sliding part.

[0027] 7. As a preferred embodiment of the utility model, the setting of the limiting flange and the limiting guide groove can ensure that the sliding part will not rotate during the sliding process, thereby increasing the accuracy of the cooperation between the spike part and the hole.

[0041] Reference Figure 1-5 A fire-resistant sealing pad installation device includes an outer shell 1, a sliding cavity 101 is provided in the outer shell 1, a sliding part 2 is slidably connected in the sliding cavity 101, a sealing member for sealing the sliding cavity 101 is provided at the end of the outer shell 1, a plurality of channels 301 communicating with the sliding cavity 101 are provided on the sealing member, a plurality of groups of spikes 201 cooperating with the channels 301 are provided on the side of the sliding part 2 close to the sealing member, the sliding part 2 slides along the sliding cavity 101 so that the spikes 201 have a first position passing through the channels 301 and a second position located in the sliding cavity 101; and a driving part for driving the sliding part 2 to slide between the first position and the second position.

[0042] It can be understood by those skilled in the art that before installing the refractory gasket on the sand core, the sand core needs to be grabbed by an automated robot and placed in a water-based coating so that the surface of the sand core is evenly coated with a layer of water-based coating. After completion, the robot places the sand core on the roller line tray, starts the roller line tray to transfer the sand core to the refractory gasket installation station, and the staff manually installs the refractory gasket through the refractory gasket installation device. Specifically, the staff drives the sliding part 2 to slide from the second position to the first position through the driving part. At this time, the tip of the spike part 201 penetrates the hole 301 through the spike part 201 and inserts into the surface of the refractory gasket to grab the refractory gasket to be installed. Then, the staff aligns the grabbed refractory gasket with the installation position of the refractory gasket on the sand core, and applies a pressure perpendicular to the refractory gasket of the sand core to the outer shell 1, so that the refractory gasket is stably attached to the sand core under the pressure of the seal and the bonding action of the water-based coating. When the refractory sealing gasket and the sand core are attached, the driving part drives the sliding part 2 to slide from the first position to the second position to separate the spike part 201 from the refractory sealing gasket, and then the thrust applied to the outer shell 1 is removed, and finally the seal is separated from the refractory sealing gasket to complete the installation of a single refractory sealing gasket.

[0043] It is worth mentioning that when the refractory sealing gasket to be installed is grabbed by the spike portion 201, the sealing member can keep the refractory sealing gasket flat during the process of grabbing and transporting the refractory sealing gasket, thereby preventing wrinkles on the refractory sealing gasket from affecting installation.

[0044] By utilizing the liquid adhesion of the water-based coating and the refractory sealing pad, the refractory sealing pad is fixed and adhered to the designated position of the sand core, eliminating the use of adhesive, reducing the gas source of the casting, and alleviating the tendency of the casting to have pores. The thorn portion 201 and the sealing member contact the refractory sealing pad to complete the grabbing, transportation and installation of the refractory sealing pad, which can prevent other parts except the refractory sealing pad from contacting the water-based coating layer on the surface of the sand core, thereby avoiding the coating layer being damaged due to contact with the coating, which affects the quality of the inner cavity of the casting.

[0045] As a preferred example of the arrangement of the channels 301 , at least three channels 301 are provided, and the three channels 301 are arranged at equal intervals along the circumference of the seal, and the number and arrangement of the spike portions 201 match the channels 301 .

[0046] The arrangement of at least three holes 301 and the spike portion 201 is helpful to increase the stability during the process of grabbing and transporting the refractory sealing pad. Figure 3 As shown, four holes 301 and four spikes 201 are provided. The four spikes 201 can provide three gripping points when gripping the refractory sealing gasket, and are also beneficial to ensure that the refractory sealing gasket is always in a flat posture during transportation.

[0047] As a specific embodiment of the sealing member, the sealing member includes a cover plate 3, which is detachably connected to the end of the outer shell 1. The end surface of the cover plate 3 can be flatly pressed onto the mounting surface of the sand core, and the detachable connection between the cover plate 3 and the outer shell 1 can be threaded or interference fit, which will not be described in detail here.

[0048] Preferably, the cover plate 3 is a circular groove structure, the inner wall of the circular groove is provided with an internal thread, and the outer end of the outer shell 1 is provided with an external thread that matches the internal thread, and the cover plate 3 can be installed, removed, and replaced by matching the internal thread with the external thread. The cover plate 3 with various hole 301 arrangements and the sliding part 2 with various spike part 201 arrangements can be designed to adapt to various shapes of refractory sealing gaskets, and the cover plate 3 and the sliding part 2 can be replaced by disassembling them.

[0049] As a preferred embodiment of the present application, refer to Figure 2 A spring 5 is fixedly connected between the sliding part 2 and the sliding cavity 101. When the sliding part 2 slides from the second position to the first position, the spring 5 is compressed and deformed, and the kinetic energy is converted into elastic potential energy. When the thrust applied to the driving part is removed, the elastic potential energy of the spring 5 is released, and the sliding part 2 is reset from the first position to the second position, thereby achieving the effect of saving manpower.

[0050] As a specific implementation of the driving rod 4 in this application, refer to Figure 1-Figure 2 The driving part includes a driving rod 4, which passes through the sliding cavity 101 from the end away from the sealing member. The end of the driving rod 4 located in the sliding cavity 101 is fixedly connected to the sliding part 2, and the end of the driving rod 4 located outside the sliding cavity 101 has an extension portion extending outside the outer shell 1.

[0051] When it is necessary to drive the sliding part 2 to move from the second position to the first position, the staff can use the palm of their hand to apply a thrust to the end of the extension part to push the driving rod 4 to push the sliding part 2 from the second position to the first position. After the thrust applied to the extension part is removed, the spring 5 returns to its original position and pulls the sliding part 2 to slide from the first position to the second position.

[0052] Furthermore, the end of the extension portion is fixedly connected with a push-pull handle 401. The push-pull handle 401 is provided to facilitate the staff to push and pull the driving rod 4.
