Description

Technical Field

[0001] This utility model relates to the field of nozzle mold technology, specifically to a nozzle outlet mold. Background Technology

[0002] Nozzles are designed to operate under various spraying conditions. Therefore, selecting the appropriate nozzle is crucial to achieving optimal spraying performance during use. The characteristics of a nozzle are mainly reflected in its spray type, which is the shape formed when the liquid leaves the nozzle orifice and its operational performance. Nozzles are named according to their spray shape, such as fan-shaped, cone-shaped, liquid column flow (i.e., jet), air atomizing, and flat nozzles. Nozzles are mostly manufactured using injection molding processes, which requires injection molds for injection production.

[0003] In faucets, multi-hole nozzles are often used to divide the water flow into multiple fine streams, which can also pass some impurities. However, because the multi-hole nozzle has many holes on its surface, and existing equipment often uses a top pin to feed the product, the nozzle surface is prone to bending outwards during the feeding process, which can easily cause the nozzle holes to crack and affect product quality.

[0004] Therefore, it is necessary to invent a nozzle outlet mold to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a nozzle outlet mold to solve the problem that the nozzle surface orifice is easily broken during the material feeding process, which affects product quality.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a nozzle outlet mold, comprising a first mounting plate, a first template, a second template, a third template, a connecting plate, a second mounting plate, and an adjusting plate. The first template, the second template, the third template, the connecting plate, and the adjusting plate are arranged sequentially from left to right between the first mounting plate and the second mounting plate. A demolding assembly is provided between the first mounting plate, the first template, the second template, the third template, the connecting plate, the second mounting plate, and the adjusting plate. The demolding assembly includes a transmission slider, a slot, a movable template, a transmission groove, a positioning sleeve, a transmission rod, a connecting block, a transmission block, an injection mold core, and an injection head.

[0007] By adopting the above technical solution, the first, second, and third templates work together to injection mold and shape the product. After the product is formed, the adjusting plate is first pulled to the right to disengage the multiple sets of protrusions on the surface of the injection head from the inside of the product. During the disengagement process, the left end of the positioning sleeve supports the product surface, thereby preventing the product from bending and being damaged. At the same time, it will drive the second and third templates to slide to the right, causing the movable template to move to both sides to demold the side of the product. Then, the third template drives the positioning sleeve to move to the right, at which point the positioning sleeve is pulled out from the inside of the product, and the product is demolded and unloaded, effectively improving the product production quality.

[0008] Optionally, inclined transmission sliders are fixedly connected to both the front and rear sides of the right side surface of the first template, and movable templates are slidably connected to both the front and rear sides of the left side surface of the second template. The transmission groove is inclinedly formed on the surface of the movable template, and the transmission slider is slidably connected to the transmission groove.

[0009] By adopting the above technical solution, as the second template slides to the right, it will drive the movable template to slide to the right. Since both the transmission slider and the transmission groove are inclined, the movable template will unfold to both sides as it slides to the right. At the same time, when the movable template slides to the outermost end, the transmission slider will still be stuck inside the transmission groove to limit the second template and prevent it from continuing to slide.

[0010] Optionally, support rods are fixedly connected to the four corners of the right side surface of the first template, and the second template, the third template, and the connecting plate are all slidably connected to the support rods.

[0011] By adopting the above technical solution, the support rod improves the stability of the second template, the third template, and the connecting plate during the sliding process.

[0012] Optionally, the two ends of the connecting plate are fixedly connected to the third template and the second mounting plate, respectively. Four sets of positioning rods are fixedly connected between the third template and the second mounting plate. The adjusting plate is slidably connected to the positioning rods. A connecting hole is provided at the center of the second mounting plate.

[0013] By adopting the above technical solution, a hydraulic cylinder is installed on the right side of the mold. The piston rod in the hydraulic cylinder passes through the connecting hole and is fixedly connected to the right side surface of the adjusting plate, thereby driving the adjusting plate to slide on the surface of the positioning rod.

[0014] Optionally, two sets of positioning sleeves are fixedly connected to the left side surface of the third template, two sets of connecting blocks are fixedly connected to the left side surface of the adjusting plate, a transmission block is fixedly connected to the left side surface of the connecting block, two sets of injection mold cores are fixedly connected to the left side surface of the transmission block, an injection head is fixedly connected to the left end of the injection mold core, and the injection mold core and injection head slide through the third template and are slidably connected to the positioning sleeves.

[0015] By adopting the above technical solution, the adjusting plate, through the cooperation of the connecting block and the transmission block, drives the injection mold core and the injection head to slide inside the positioning sleeve.

[0016] Optionally, four sets of transmission rods are fixedly connected to the left side surface of the third template, and all four sets of transmission rods are slidably connected to the second template. Four sets of slots are provided on the right side surface of the first template.

[0017] By adopting the above technical solution, the transmission rod is used to drive the second template to slide to the right. When the mold is closed, the left end of the transmission rod will be stuck in the slot.

[0018] Optionally, an injection port is provided at the center of the first mounting plate, and two sets of first injection grooves are provided on the right side surface of the first template.

[0019] By adopting the above technical solution, the injection port is used to inject materials into the mold, and the first injection groove is used to shape the shape of the left end of the product.

[0020] Optionally, the surface of the second template is provided with two sets of insertion grooves, and the surfaces of the two sets of movable templates that are close to each other are provided with two sets of second injection grooves, and an injection hole is provided between the two sets of second injection grooves.

[0021] By adopting the above technical solution, the positioning sleeve is inserted into the insertion groove. Multiple sets of through holes are opened at the left end of the positioning sleeve. The injection head passes through the through holes at the left end of the positioning sleeve. The injection groove is provided with internal threads to make the surface of the product injection molded with external threads.

[0022] The technical effects and advantages provided by this utility model in the above technical solution are as follows: This invention utilizes a hydraulic cylinder to slide an adjusting plate to the right, disengaging multiple sets of protrusions on the injection head surface from the product's interior. During this disengagement, the left end of the positioning sleeve supports the product surface, preventing bending damage. The positioning sleeve is then pulled out of the product's interior, at which point the movable templates on both sides support the product's sides. Finally, the movable templates slide to both sides to demold the product's sides, allowing for demolding and unmolding. By employing segmented core pulling, the tensile force on the product surface during core pulling is effectively reduced, thus minimizing damage and improving product quality.

[0025] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0026] This utility model provides, for example Figures 1 to 6 The nozzle outlet mold shown includes a first mounting plate 1, a first template 2, a second template 3, a third template 4, a connecting plate 5, a second mounting plate 6, and an adjusting plate 7. The first template 2, second template 3, third template 4, connecting plate 5, and adjusting plate 7 are arranged sequentially from left to right between the first mounting plate 1 and the second mounting plate 6. A demolding assembly is provided between the first mounting plate 1, first template 2, second template 3, third template 4, connecting plate 5, second mounting plate 6, and adjusting plate 7. The demolding assembly includes a transmission slider. 22. Slot 24, movable template 32, transmission slide 33, positioning sleeve 41, transmission rod 43, connecting block 71, transmission block 72, injection mold core 73 and injection head 74. An injection port 11 is provided at the center of the first mounting plate 1. Two sets of first injection grooves 21 are provided on the right side surface of the first template 2. Two sets of insertion grooves 31 are provided on the surface of the second template 3. Two sets of second injection grooves 34 are provided on the side surface of the two movable templates 32 that are close to each other. An injection hole 35 is provided between the two sets of second injection grooves 34.

[0027] In this process, the first template 2, the second template 3, and the third template 4 are closed. At this time, the positioning sleeve 41 is inserted into the inside of the insertion slot 31, and the injection head 74 passes through the through hole at the left end of the positioning sleeve 41 to form a mold core on the left side of the second template 3, which shapes the inside of the product. At the same time, the two sets of movable templates 32 are closed, and the first injection groove 21 and the second injection groove 34 are combined to form a molding groove.

[0028] During the injection molding process, an extruder is used to inject materials into the upper and lower molding grooves through the injection port 11 and injection hole 35 respectively for injection molding production.

[0029] In addition, during the demolding process, the hydraulic cylinder is used to pull the adjusting plate 7, the third template 4 and the second template 3 to the right. First, the injection head 74 is pulled out from the inside of the product. Then, the two sets of movable templates 32 are unfolded. Finally, the positioning sleeve 41 is pulled out from the inside of the product to demold the product.

[0030] See Figures 2 to 6 Inclined transmission sliders 22 are fixedly connected to both the front and rear sides of the right side surface of the first template 2. Movable templates 32 are slidably connected to both the front and rear sides of the left side surface of the second template 3. Transmission grooves 33 are inclinedly formed on the surface of the movable templates 32. The transmission sliders 22 are slidably connected to the transmission grooves 33. Support rods 23 are fixedly connected to the four corners of the right side surface of the first template 2. The second template 3, the third template 4, and the connecting plate 5 are all slidably connected to the support rods 23. The two ends of the connecting plate 5 are fixedly connected to the third template 4 and the second mounting plate 6, respectively. Four sets of positioning rods 42 are fixedly connected between the third template 4 and the second mounting plate 6. The adjusting plate 7 is slidably connected to the positioning rods 42. The second mounting plate 6 has a connecting hole 61 at its center. Two sets of positioning sleeves 41 are fixedly connected to the left side surface of the third template 4. Two sets of connecting blocks 71 are fixedly connected to the left side surface of the adjusting plate 7. A transmission block 72 is fixedly connected to the left side surface of the connecting block 71. Two sets of injection mold cores 73 are fixedly connected to the left side surface of the transmission block 72. An injection head 74 is fixedly connected to the left end of the injection mold core 73. The injection mold core 73 and the injection head 74 pass through the third template 4 and are slidably connected to the positioning sleeves 41. Four sets of transmission rods 43 are fixedly connected to the left side surface of the third template 4. All four sets of transmission rods 43 are slidably connected to the second template 3. Four sets of slots 24 are opened on the right side surface of the first template 2.

[0031] Specifically, during mold closing, the piston rod in the hydraulic cylinder pushes the adjusting plate 7 to the left, thereby causing the connecting block 71, transmission block 72, injection mold core 73, and injection head 74 to slide to the left. When the transmission block 72 abuts against the surface of the third template 4, the injection head 74 just extends from the left end of the positioning sleeve 41. At this time, the adjusting plate 7 pushes the third template 4, connecting plate 5, and second mounting plate 6 to the left together through the transmission block 72, inserting the positioning sleeve 41 into the insertion slot 31 until the surfaces of the third template 4 and the second template 3 abut against each other. At this time, the adjusting plate 7 will push the second template 3 to the left through the third template 4. Then, with the cooperation of the transmission slider 22 and the transmission groove 33, the two sets of movable templates 32 will slide inward and close together. When the movable templates 32 are completely close together, the left end of the movable template 32 will abut against the surface of the first template 2.

[0032] In addition, during demolding, the piston rod in the hydraulic cylinder pulls the adjusting plate 7 to the right, which in turn drives the connecting block 71, transmission block 72, injection mold core 73, and injection head 74 to slide to the right. This causes the injection mold core 73 and injection head 74 to slide to the right inside the positioning sleeve 41, allowing the injection head 74 to be withdrawn from the hole on the product surface and retracted into the positioning sleeve 41. During the withdrawal process, the left end of the positioning sleeve 41 supports the surface of the product, thereby preventing bending around the hole on the product surface, reducing product damage, and effectively improving product quality.

[0033] Simultaneously, as the adjusting plate 7 continues to slide to the right, when the adjusting plate 7 abuts against the surface of the second mounting plate 6, it drives the second mounting plate 6, the connecting plate 5, and the third template 4 to slide to the right, thereby driving the positioning sleeve 41 to slide to the right, causing the positioning sleeve 41 to be pulled out from the inside of the product. When the left end of the transmission rod 43 abuts against the surface of the second template 3, it will pull the second template 3 to the side, which, together with the transmission slider 22 and the transmission groove 33, causes the two sets of movable templates 32 to unfold to both sides, detaching the product from the inside of the first injection molding groove 21 and the second injection molding groove 34, thus completing the unloading.

[0034] The working principle of this utility model is as follows: The hydraulic cylinder drives the adjusting plate 7 to slide to the right, which disengages multiple sets of protrusions on the surface of the injection head 74 from the inside of the product. During the disengagement process, the left end of the positioning sleeve 41 supports the product surface, thereby preventing the product from bending and being damaged. Then, the positioning sleeve 41 is pulled out from the inside of the product. At this time, the movable templates 32 on both sides support the side of the product. Finally, the movable templates 32 are driven to slide to both sides to demold the side of the product, and the product is demolded and unloaded. By adopting segmented core pulling, the tensile force on the product surface during the core pulling process is effectively reduced, thereby reducing damage to the product and effectively improving the product production quality.

[0035] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
