Description

Technical Field

[0001] This invention relates to the field of injection molding machine technology, and specifically to an injection molding machine for a shower enclosure base. Background Technology

[0002] A shower enclosure is a separate shower stall in a family bathroom. Modern homes have increasingly higher requirements for bathroom facilities, and many families desire a separate bathing space. However, due to limited bathroom space, bathing facilities and sanitary ware must be placed in one room. A shower enclosure makes full use of a corner of the room, clearly defining the shower area with a partition, forming a relatively independent bathing space and achieving dry and wet separation in the bathroom. A shower enclosure generally consists of a base and a glass door installed on the base. The shower enclosure base is commonly made of ABS material using a blow molding process. Because blow molding stretches the sheet material, some areas of the shower enclosure base are relatively thin. To improve the strength of the shower enclosure base, existing technology uses methods such as coating the base with reinforcing adhesive. However, this reinforcing adhesive has a strong, pungent odor, which can affect the health of workers during production and produce a pungent odor during use, affecting the user experience. To overcome the problems of shower enclosure bases made using the blow molding process, this invention uses injection molding to produce a shower enclosure base made of PVC material. Because the shower enclosure base is large, the product is still at a high temperature when the existing injection molding machine demolds. The working environment for manual demolding is also high, and the product needs to be left for a long time to cool down to room temperature after being removed, which is not conducive to improving production efficiency.

[0033] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0034] like Figures 1 to 3 As shown, a shower room base injection molding machine includes: an injection molding machine, an automatic feeding mechanism, an air-cooling mechanism, and a circulating placement rack.

[0035] like Figure 4 As shown, the injection molding machine includes a base 1 and a feeding and melting mechanism 2, an injection mechanism 3, and a mold closing mechanism 4, all mounted on the base 1. The feeding and melting mechanism 2 is used for feeding and melting polymer materials. The injection mechanism 3 injects the molten material into the mold closing mechanism 4. The mold closing mechanism 4 includes a first mold 41 and a second mold 42. The first mold 41 moves closer to or further away from the second mold 42 under the action of a propulsion mechanism, forming a mold cavity after mold closing.

[0036] like Figure 5As shown, the automatic unloading mechanism includes a moving material picking mechanism 5 and an unloading mechanism 6. The moving material picking mechanism 5 includes a clamping mechanism that can move back and forth between the mold closing mechanism 4 and the unloading mechanism 6. The unloading mechanism 6 is located on one side of the base 1 and includes a feeding plate 8 and a pushing device 9. The clamping mechanism is used to clamp the molded product onto the feeding plate 8, the feeding plate 8 is used to place the finished product brought from the mold closing mechanism 4 by the moving material picking mechanism 5, and the pushing device 9 pushes the finished product into the circulating placement rack.

[0037] The air-cooling mechanism is located between the moving material handling mechanism 5 and the unloading mechanism 6, which can accelerate the cooling of the finished product, reduce the temperature of the finished product, and facilitate subsequent processing.

[0038] The circulating placement rack includes a fixed plate 10 and several feeding racks 11, which move cyclically along a circular track 12 set on the fixed plate 10. This allows for the reciprocating transport of finished products to the next processing step.

[0039] Specifically, such as Figures 6 to 8 As shown, the moving material handling mechanism 5 includes a vertical plate 51, a guide rail 52, a drive mechanism, a sliding plate 53, an upper clamping plate 54, and a side clamping plate 55.

[0040] The upright plate 51 is fixed to the base 1 and is arranged corresponding to the mold closing mechanism 4. One end of the guide rail 52 is fixed to the upright plate 51, extends horizontally to one side to the unloading mechanism 6, and is located between the first mold 41 and the second mold 42, so as to drive the finished product located between the first mold 41 and the second mold 42 after demolding. Preferably, the guide rail 52 includes two circular sliding rods, which are arranged horizontally and parallel to each other.

[0041] The slide plate 53 is slidably mounted on the guide rail 52 and is driven to move back and forth by a drive mechanism. The slide plate 53 is rectangular, with connecting parts at its four bottom corners that are slidably connected to the guide rail 52. These connecting parts are slidably connected to circular sliding rods. Preferably, the drive mechanism includes a drive motor 56 and a lead screw 57. The drive motor 56 is fixed to the upright plate 51, and its output end is connected to the lead screw 57. The lead screw 57 is parallel to the guide rail 52 and threadedly connected to the slide plate 53. A protrusion is provided at the bottom of the slide plate 53, and the lead screw 57 is threadedly connected to this protrusion. The drive motor 56 drives the lead screw 57 to rotate, and the rotation of the lead screw 57 causes the protrusion and the slide plate 53 to move.

[0042] The upper clamping plate 54 is vertically and flexibly positioned below the slide plate 53 via a lifting cylinder 58. The lifting cylinder 58 is fixed above the slide plate 53, and its push rod is fixedly connected to the top of the upper clamping plate 54. Furthermore, the lifting cylinder 58 is located at the center of the slide plate 53, which is also at the center of the upper clamping plate 54. To avoid the lifting cylinder 58 overlapping with the drive mechanism, a protrusion is provided on one side of the center of the slide plate 53.

[0043] Two side clamps 55 are positioned below the upper clamp 54 and are moved closer or further apart via a translation mechanism. Preferably, the translation mechanism includes a translation motor 59 and a translation screw 510. A sliding groove 511 is provided at the center line of the upper clamp 54, and a slider 512 is provided at the midpoint of the top of the side clamps 55. The slider 512 extends upward and slides in the sliding groove 511, with its top extending above the upper clamp 54. The translation screw 510 has two sets of opposing threads symmetrically arranged on its surface, and these threads are threadedly connected to the two sliders 512 respectively. One end of the translation screw 510 is connected to the translation motor 59, which drives the translation screw 510 to rotate, thereby causing the two side clamps 55 to move closer or further apart to clamp the shower enclosure base.

[0044] like Figure 10 and Figure 11 As shown, the unloading mechanism 6 includes a fixed upright plate 61, which is positioned corresponding to the upright plate 51 and fixedly connected to the other end of the guide rail 52. The unloading plate 8 is fixed to the fixed upright plate 61 and is inclined towards the circulating placement rack to facilitate the movement of the finished product onto the rack. Two sets of pushing devices 9 are distributed on both sides of the unloading plate 8, one high and one low. Due to the arrangement of the mold closing mechanism 4, the shower room base is vertical after demolding, but needs to be horizontal when placed on the circulating placement rack; therefore, two pushing devices 9 are used to adjust the placement of the finished product. When the clamping mechanism holds the finished product above the feeding plate 8, it releases it, and the finished product falls onto the feeding plate 8. Since the feeding plate 8 is tilted, the finished product will tilt towards one side of the circulating placement rack and fall onto a pushing device 9. At this time, the pushing device 9 is activated. The pushing device 9 on the side away from the circulating placement rack pushes the finished product downward towards the circulating placement rack, while the pushing device 9 on the side closer to the circulating placement rack pushes the finished product upward away from the circulating placement rack, so that the finished product becomes horizontal and moves along the tilted feeding plate 8 onto the circulating placement rack.

[0045] Preferably, the pushing device 9 includes a connecting plate 91, a pushing cylinder 92, and a pushing rod 93. The connecting plate 91 is connected to the fixed upright plate 61 and extends towards the dispensing plate 8. The pushing cylinder 92 is fixed to the fixed upright plate 61, and its push rod is fixedly connected to the pushing rod 93. The moving plane of the pushing rod 93 is close to or away from the circulating placement frame, and its moving plane is parallel to the inclined plane of the dispensing plate 8. The pushing rod 93 can push the finished product under the action of the pushing cylinder 92.

[0046] Furthermore, the pusher device 9 near the circulating placement rack has an adjustable height via a lifting mechanism to accommodate shower enclosure bases of different heights, allowing the finished product to pass between the pusher device 9 and the placement plate 8. The lifting mechanism includes an extension plate 94, a lifting slide rod 95, and a lifting screw 96. The extension plate 94 extends from the fixed upright plate 61 toward the circulating placement rack. The lifting slide rod 95 is fixed to the extension plate 94 and extends downward to be slidably connected to the connecting plate 91. The lifting screw 96 is rotatably mounted on the extension plate 94, extending at the top to the top of the extension plate 94 and fixedly connected to the handle 97, and at the bottom to the bottom of the extension plate 94 and threadedly connected to the connecting plate 91. In use, the handle 97 drives the lifting screw 96 to rotate, which in turn drives the connecting plate 91 to rise and fall synchronously with the pusher cylinder 92 and the pusher rod 93.

[0047] like Figure 9 As shown, the air-cooling mechanism is a ring-blowing cooling mechanism 13, which includes a base 131, a ring-blowing air duct 132, and a fan 133. The ring-blowing air duct 132 is U-shaped, with an air outlet on its inner side, and its bottom is fixedly connected to the base 131. The fan 133 is connected to the ring-blowing air duct 132. The ring-blowing cooling mechanism 13 can simultaneously cool the shower room base in multiple directions, resulting in high cooling efficiency and good effect.

[0048] like Figure 12 As shown, two fixed plates 10 are arranged opposite each other, and the feeding rack 11 is located between the two fixed plates 10. Driven by the driving device, it moves cyclically along the circular track 12. This moves the finished products to the other side for easy loading and unloading by workers.

[0049] Working process: After the injection molding machine finishes injection molding and cools and forms the finished product, the first mold 41 and the second mold 42 separate. The finished product of the shower room base is demolded under the action of the demolding mechanism. Then, the moving material picking mechanism 5 moves between the first mold 41 and the second mold 42, picks up the finished product downwards and returns. Then, it moves along the guide rail, passes through the air cooling mechanism, and is placed down by the unloading mechanism 6. The finished product is changed in place by the pushing mechanism 9 and moved to the circulating placement rack. The circulating placement rack then drives it to the other side to enter the next process.

[0050] The preferred embodiments of the present invention have been described in detail above. It should be understood that those skilled in the art can make numerous modifications and variations based on the concept of the present invention without creative effort. Therefore, all technical solutions that can be obtained by those skilled in the art based on the concept of the present invention through logical analysis, reasoning, or limited experimentation on the basis of existing technology should be within the scope of protection defined by the claims.
