Technical Field

[0001] This utility model relates to the field of foaming mold technology, and in particular to a foaming molding equipment with a pre-embedded positioning mechanism. Background Technology

[0002] Currently, in the traditional pre-embedded process of foam molds, workers usually position and fix the pre-embedded parts directly in the cavity of the foam mold using fasteners. After the product has foamed and formed, workers simply break the fasteners to remove the product.

[0003] However, the fasteners used in this traditional pre-embedded process are not only non-reusable, but they also easily tear the product when it is removed, leading to a decrease in product yield. Furthermore, direct positioning with fasteners results in low positional accuracy of the pre-embedded parts, ultimately affecting product quality. Utility Model Content

[0004] The purpose of this utility model is to provide a foaming molding equipment with a pre-embedded positioning mechanism, which aims to solve or at least partially solve the shortcomings of the above-mentioned background technology. It can realize the precise pre-embedded positioning of the pre-embedded parts, the foaming molding of the product, and the smooth demolding of the product. It has a manual control air circuit and an automatic control air circuit set in parallel, and the manual control valve is placed on the machine base, which not only increases the convenience and safety of the staff in the trial production, production and maintenance process, but also improves the production efficiency.

[0005] This utility model provides a foaming molding equipment with a pre-embedded positioning mechanism, including a machine base, a foaming mold, an air source, and a controller. The foaming mold, air source, and controller are respectively mounted on the machine base, which is equipped with a housing. The foaming mold includes an upper mold, a lower mold, a pre-embedded positioning mechanism, and a mold opening and closing mechanism. The upper mold, lower mold, and mold opening and closing mechanism are all located within the accommodating space of the housing. The mold opening and closing mechanism is used to drive the opening and closing of the upper and lower molds. A cavity for molding products is provided between the upper and lower molds. The pre-embedded positioning mechanism includes a positioning cylinder mounted on the lower mold and a manual control valve connected to the positioning cylinder at one end. The positioning cylinder has a telescopic rod that can pass through the lower mold and move the pre-embedded part to a predetermined position in the cavity. An automatic control valve is integrated inside the positioning cylinder. Both ends of the automatic control valve are connected to the positioning cylinder and the air source, respectively. The other end of the manual control valve is connected to the air source and is located on the outer surface of the housing. The controller is electrically connected to the positioning cylinder and the mold opening and closing mechanism.

[0006] Furthermore, the end of the telescopic rod is recessed along the axial direction with a limiting groove for positioning the embedded part, and a magnetic block for magnetically fixing the embedded part is embedded in the limiting groove.

[0007] Furthermore, the lower mold has a first guide hole that mates with the telescopic rod, and the pre-embedded positioning mechanism also includes a guide block. The guide block is fixed on the side wall of the lower mold and located between the lower mold and the positioning cylinder. The guide block has a second guide hole that mates with the telescopic rod, and the first guide hole and the second guide hole are connected.

[0008] Furthermore, a sealing ring is provided between the positioning cylinder and the guide block.

[0009] Furthermore, the mold opening and closing mechanism includes a support platform and a fixed plate. The lower mold is fixed on the upper surface of the support platform, and an ejection cylinder for ejecting the product is embedded in the support platform. The fixed plate is mounted on the support platform and located above the foaming mold. A lifting cylinder for driving the upper mold to rise and fall is provided on the fixed plate.

[0010] Furthermore, both the lifting cylinder and the ejection cylinder are electrically connected to the controller.

[0011] Furthermore, the foaming molding equipment with a pre-embedded positioning mechanism is provided with an operating area, which is located between the machine casing and the air source. The manual control valve is located on the side wall of the machine casing and within the operating area.

[0012] Furthermore, the side wall of the housing is provided with an openable and closable protective cover, which covers the outside of the manual control valve when closed.

[0013] Furthermore, the positioning cylinder is located on the side wall of the lower mold near the manual control valve.

[0014] Furthermore, it also includes a display screen, which is set on the machine base and located in the operating area. The positioning cylinder integrates a displacement sensor, which is used to measure the extension distance of the telescopic rod. The display screen displays the value of the extension distance of the telescopic rod in real time.

[0015] This utility model provides a foaming molding equipment with a pre-embedded positioning mechanism. Through the cooperation of the upper mold, lower mold, pre-embedded positioning mechanism, and mold opening and closing mechanism, it achieves accurate pre-embedded positioning of the pre-embedded parts, foaming molding of the product, and smooth demolding of the product.

It should be understood that the use of directional terms should not limit the scope of protection claimed in this application.

[0027] Please see Figures 1-3 A foaming molding equipment with a pre-embedded positioning mechanism includes a machine base 10, a foaming mold 20, an air source 30, and a controller 40. The foaming mold 20, the air source 30, and the controller 40 are respectively installed on the machine base 10, and a housing 11 is installed on the machine base 10.

[0028] The foaming mold 20 includes an upper mold 21, a lower mold 22, a pre-embedded positioning mechanism 23, and an opening and closing mechanism 24. The upper mold 21, lower mold 22, and opening and closing mechanism 24 are all housed within the accommodating space 111 of the housing 11. The opening and closing mechanism 24 drives the opening and closing of the upper mold 21 and lower mold 22. A cavity 25 for molding products is provided between the upper mold 21 and lower mold 22. More specifically, a machine platform door 112 is provided on the front of the housing 11, and an observation window 113 is provided on the machine platform door 112. The observation window 113 facilitates the observation and maintenance of the foaming mold 20 by the staff. The upper mold 21 has a raw material injection port 211.

[0029] The pre-embedded positioning mechanism 23 includes a positioning cylinder 231 disposed in the lower mold 22 and a manual control valve 232 connected to the positioning cylinder 231 at one end. The positioning cylinder 231 has a telescopic rod 233 that can pass through the lower mold 22 and drive the pre-embedded part 100 to move to the predetermined position of the cavity 25. An automatic control valve (not shown) is integrated inside the positioning cylinder 231. The two ends of the automatic control valve are connected to the positioning cylinder 231 and the air source 30, respectively. The other end of the manual control valve 232 is connected to the air source 30 and is located on the outer surface of the housing 11.

[0030] The controller 40 is electrically connected to the positioning cylinder 231 and the mold opening and closing mechanism 24, respectively. The controller 40 is used to control and coordinate the operation of the positioning cylinder 231 and the mold opening and closing mechanism 24. The air source 30 is used to provide compressed gas to the cylinders on the foaming molding equipment with the pre-embedded positioning mechanism.

[0031] More specifically, the controller 40 is electrically connected to the automatic control valve. The positioning cylinder 231 and the air source 30 form an automatic control air circuit and a manual control air circuit arranged in parallel. The automatic control valve is located in the automatic control air circuit and controls the flow rate and pressure of the compressed air from the air source 30 through the program settings of the controller 40 to drive the telescopic rod 233 to actuate. The manual control valve 232 is located in the manual control air circuit and controls the flow rate and pressure of the compressed air from the air source 30 through manual adjustment to drive the telescopic rod 233 to actuate.

[0032] The manual control air circuit is normally closed. When it is necessary to manually adjust the telescopic rod 233, the controller 40 can close the automatic control air circuit by controlling the automatic control valve, thereby switching to the manual adjustment mode. The operator can then adjust the telescopic rod 233 by operating the manual control valve 232.

[0033] It should be noted that sometimes the automatic control valve may cause the telescopic rod 233 to be inaccurately positioned due to parameter deviation. In this case, it is necessary to switch to manual adjustment mode. The operator can use the manual control valve 232 to achieve millimeter-level precision alignment of the embedded part 100, thereby ensuring that the embedded part 100 is in the correct position when the mold is closed.

[0034] As described above, the foaming molding equipment with a pre-embedded positioning mechanism provided by this utility model, through the cooperation of the upper mold 21, lower mold 22, pre-embedded positioning mechanism 23, and mold opening and closing mechanism 24, achieves accurate pre-embedded positioning of the pre-embedded part 100, foaming molding of the product, and smooth demolding of the product; through the cooperation of the automatic control valve, the manual control valve 232, and the controller 40, an automatic control air circuit and a manual control air circuit are formed in parallel, realizing automatic or manual control of the telescopic rod 233 of the positioning cylinder 231. The operator can fine-tune the telescopic rod 233 through the manual control valve 232 to ensure that the pre-embedded part 100 is accurately in place; by setting the manual control valve 232 externally, when the operator performs process fine-tuning of the telescopic rod 233 or repairs the manual control valve 232, there is no need to open the machine door 112 first and then manually control the valve 232, which increases the convenience of the operator in the trial production, production, and maintenance process, shortens the product production cycle, improves production efficiency, and avoids the operator from contacting the high-temperature surface of the foaming mold 20, thus improving production safety.

[0035] Please see Figure 4 and Figure 6The end of the telescopic rod 233 is recessed along the axial direction with a limiting groove 234 for positioning the embedded part 100. More specifically, the embedded part 100 is provided with a mounting protrusion 101 that cooperates with the limiting groove 234. Through the cooperation between the mounting protrusion 101 and the limiting groove 234, the embedded part 100 can be prevented from radially shifting during the foaming process in the mold.

[0036] Furthermore, the limiting groove 234 is embedded with a magnetic block 235 for magnetically fixing the embedded part 100. The magnetic block 235 magnetically fixes the embedded part 100 to prevent it from falling off; in addition, the magnetic connection between the magnetic block 235 and the embedded part 100 allows the telescopic rod 233 to smoothly detach from the embedded part 100 when it exits the cavity 25, avoiding damage to the product.

[0037] Please see Figures 4-6 The lower mold 22 has a first guide hole 221 that mates with the telescopic rod 233. The pre-embedded positioning mechanism 23 also includes a guide block 222, which is fixed to the side wall of the lower mold 22 and located between the lower mold 22 and the positioning cylinder 231. The guide block 222 has a second guide hole 224 that mates with the telescopic rod 233. The first guide hole 221 and the second guide hole 224 are connected. Through the cooperation of the first guide hole 221 and the second guide hole 224, they are connected to form a longer guide hole, which makes the telescopic rod 233 more stable during the extension and retraction process, thereby ensuring the accurate positioning of the pre-embedded part 100.

[0038] More specifically, the inner diameters of the first guide hole 221 and the second guide hole 224 are the same, and the outer diameter of the telescopic rod 233, the inner diameter of the first guide hole 221, and the inner diameter of the second guide hole 224 are equal to maintain the sealing of the cavity 25.

[0039] Furthermore, a sealing ring 223 is provided between the positioning cylinder 231 and the guide block 222, which enhances the sealing performance of the cavity 25 of the foaming mold 20. The guide block 222 also has a recessed positioning groove 225 for mounting the positioning cylinder 231 on its side facing the positioning cylinder 231. Through the cooperation of the positioning groove 225 and the positioning cylinder 231, the telescopic rod 233 of the positioning cylinder 231 can be aligned with the second guide hole 224. The guide block 222 also has a coaxial receiving groove 226 on the positioning groove 225 for accommodating the sealing ring 223. Through the cooperation of the receiving groove 226 and the sealing ring 223, the sealing performance of the cavity 25 is further enhanced.

[0040] Please see Figure 3The mold opening and closing mechanism 24 includes a support platform 241 and a fixing plate 242 disposed in the accommodating space 111. The lower mold 22 is fixed on the upper surface of the support platform 241. The support platform 241 is embedded with an ejection cylinder 243 for ejecting the product. The fixing plate 242 is mounted on the support platform 241 and located above the foaming mold 20. The fixing plate 242 is provided with a lifting cylinder 244 for driving the upper mold 21 to rise and fall. The lifting cylinder 244 is connected to the upper mold 21.

[0041] Furthermore, the movable end of the ejector cylinder 243 passes through the bottom wall of the lower mold 22 and is connected to the ejector plate 245. When the mold is closed, the ejector plate 245 is embedded in the inner bottom wall of the lower mold 22. When the mold is demolded, the ejector cylinder 243 drives the ejector plate 245 to eject the product upward.

[0042] Furthermore, both the lifting cylinder 244 and the ejection cylinder 243 are electrically connected to the controller 40, and the controller 40 coordinates the operation of the lifting cylinder 244 and the ejection cylinder 243.

[0043] Please see Figure 1 and Figure 2 The foaming molding equipment with a pre-embedded positioning mechanism is provided with an operating area 50, which is located between the housing 11 and the air source 30. A manual control valve 232 is located on the side wall of the housing 11 and within the operating area 50. The manual control valve 232 is not located on the front of the housing 11 to prevent accidental activation by operators.

[0044] Furthermore, a closable protective cover 114 is provided on the side wall of the housing 11. When closed, the protective cover 114 covers the periphery of the manual control valve 232 to prevent accidental activation. One end of the anti-slip cover is hinged to the side wall of the housing 11. When the operator needs to operate the manual control valve 232, the manual control valve 232 can be operated by opening the protective cover 114.

[0045] Furthermore, the positioning cylinder 231 is installed on the side wall of the lower mold 22 near the manual control valve 232, which shortens the distance between the positioning cylinder 231 and the manual control valve 232, thereby reducing the loss of compressed air pressure in the manual control air circuit.

[0046] Furthermore, the foaming molding equipment with a pre-embedded positioning mechanism also includes a display screen 60 and a control panel 70. The display screen 60 and the control panel 70 are mounted on the machine base 10 and located within the operating area 50. The display screen 60 and the control panel 70 are electrically connected to the controller 40.

[0047] The positioning cylinder 231 integrates a displacement sensor (not shown in the figure). The displacement sensor is used to measure the extension distance of the telescopic rod 233. The display screen 60 displays the value of the extension distance of the telescopic rod 233 in real time, so as to facilitate the staff to judge whether the embedded part 100 is accurately in place.

[0048] Operators can switch between automatic and manual control of the air circuit via the control panel 70.

[0049] The production process of this foaming molding equipment with a pre-embedded positioning mechanism: (1) Initial state: The program of controller 40 by default controls the operation of the telescopic rod 233 of positioning cylinder 231 through the automatic control valve.

[0050] (2) Install the embedded parts: When the foaming mold 20 is in the open state, install the embedded parts 100 into the limiting groove 234 of the telescopic rod 233.

[0051] (3) Mold closing: Start the program through the control panel 70, and the controller 40 starts the lifting cylinder 244. The lifting cylinder 244 drives the upper mold 21 to move down and approach the lower mold 22. When the upper mold 21 and the lower mold 22 are closed, the controller 40 controls the lifting cylinder 244 to stop working and starts the positioning cylinder 231. The telescopic rod 233 of the positioning cylinder 231 drives the embedded part 100 to penetrate into the cavity 25. After the embedded part 100 reaches the predetermined position, the controller 40 controls the positioning cylinder 231 to stop working. If the embedded part 100 does not reach the predetermined position, the operator switches to manual adjustment mode through the control panel 70. The controller 40 controls the automatic adjustment valve to close, and the operator manually operates the manual adjustment valve to fine-tune the extension distance of the telescopic rod 233 so that the embedded part 100 is accurately in place. After the operation is completed, the operator continues to start the program through the control panel 70.

[0052] (4) Feeding and foaming molding: The foaming material is injected into the cavity 25 through the material injection port 211 for foaming molding. After cooling and molding, the controller 40 starts the positioning cylinder 231, the telescopic rod 233 disengages from the embedded part 100 and exits the cavity 25, and the controller 40 controls the positioning cylinder 231 to stop working.

[0053] (5) Demolding: The controller 40 starts the lifting cylinder 244, which drives the upper mold 21 to move upward to separate from the lower mold 22. The controller 40 controls the lifting cylinder 244 to stop working. Subsequently, the controller 40 starts the ejection cylinder 243, which drives the ejection plate 245 to move upward to eject the product. The product is separated from the lower mold 22, and the staff can take out the product to complete the demolding.

[0054] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in this utility model should be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
