Description

Technical Field

[0001] The present application relates to the field of mold technology, and in particular to a molding mold for processing acrylic shower trays. Background Art

[0002] A shower tray, also known as a shower base or shower tray, is a crucial component of a shower room. It primarily serves to hold accumulated water from showering, ensuring it drains smoothly and preventing it from overflowing into other areas of the bathroom. The shower tray is formed by pressing the acrylic material into a mold using a press. After the shower tray is formed, it is typically demolded manually. Compared to automated demolding methods, manual demolding is slower and requires more time and human resources, which can reduce the overall efficiency of the production line. This is especially true in high-volume production, where manual demolding can become a production bottleneck. Furthermore, the manual demolding process requires considerable effort, resulting in lower demolding efficiency for the shower tray. Utility Model Content

[0003] The purpose of the utility model is to provide a forming mold for processing an acrylic shower tray in view of the defects and shortcomings of the prior art.

[0004] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0005] It includes an upper mold and a lower mold, a cavity is formed between the upper mold and the lower mold, and a base frame is provided on the lower end surface of the lower mold. The lower mold includes a bottom plate, an arc plate and two side plates. The arc plate and the two side plates are respectively located on three sides of the bottom plate. The two side plates are respectively rotatably connected to the adjacent two side walls of the bottom plate. A driving device is provided between the side plate and the base frame, and the driving device drives the side plates to rotate.

[0006] Preferably, the driving device is a driving cylinder, one end of the driving cylinder is rotatably connected to the side wall of the side plate, and the other end of the driving cylinder is rotatably connected to the base frame.

[0007] Preferably, a pushing cylinder is provided on the outer side of the arc plate, and the pushing cylinder drives the arc plate to approach or move away from the bottom plate.

[0008] Preferably, a slider is provided at the bottom of the arc plate, and a sliding groove is provided on the upper end surface of the base frame, and the slider is inserted and slidably moved in the sliding groove.

[0009] Preferably, a tear edge groove is provided on the circumferential side of the bottom plate.

[0010] Preferably, the base plate is provided with a push rod at the bottom of the cavity, and a push-out cylinder is provided at the lower end of the push rod.

[0011] Preferably, a guide column is provided at the upper end of the side plate, and a guide hole for inserting the upper end of the guide column is opened on the lower end surface of the upper mold.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. The acrylic material is placed in the cavity between the lower mold and the upper mold. Then, driven by the press, the upper mold and the lower mold are pressed against each other to form the acrylic into a shower tray. The upper mold is then lifted upward by the press. The driving cylinder is then activated to rotate the side plates. At the same time, the push cylinder is activated to drive the arc plate away from the bottom plate. The formed shower tray is then removed from the bottom plate. In summary, this improves the convenience of demolding the shower tray.

[0014] 2. When the arc plate slides on the base frame, the slider slides in the slide groove, which improves the stability of the arc plate movement;

[0015] 3. After the upper mold and the lower mold are separated, the ejection cylinder is started to move the ejector rod upward, thereby separating the shower base from the lower mold, further improving the convenience of demolding the shower base. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] The present invention will be further described below with reference to the accompanying drawings.

[0020] The embodiment of the present application discloses a forming mold for processing an acrylic shower tray.

[0021] Reference Figure 1 , including an upper mold 1 and a lower mold 2, the lower mold 2 is located on a base frame 3, the upper mold 1 is placed above the lower mold 2, and a cavity 4 is formed between the upper mold 1 and the lower mold 2.

[0022] Reference Figure 2The lower mold 2 includes a bottom plate 5, an arc plate 6 and two side plates 7. The bottom plate 5 is fan-shaped. The two side plates 7 are respectively located on the adjacent two sides of the bottom plate 5. The arc plate 6 is located on the arc-shaped side wall of the bottom plate 5. The lower end of the side plate 7 is rotatably connected to the side wall of the bottom plate 5. There is a driving device 8 between the side plate 7 and the base frame 3. The driving device 8 is a driving cylinder 9. One end of the driving cylinder 9 is rotatably connected to the outer side of the side plate 7, and the other end of the driving cylinder 9 is rotatably connected to the upper end surface of the base frame 3. A pushing cylinder 10 is horizontally placed on the outer side of the arc plate 6, and the output end of the pushing cylinder 10 is fixed to the outer side of the arc plate 6. The acrylic raw material is placed in the cavity 4 between the lower mold 2 and the upper mold 1. Then, driven by the press, the upper mold 1 and the lower mold 2 are pressed against each other to press the acrylic into a shower tray. The upper mold 1 is then lifted upward by the press. The driving cylinder 9 is then started to rotate the side plate 7. At the same time, the pushing cylinder 10 is started to drive the arc plate 6 away from the bottom plate 5. The formed shower tray is then removed from the bottom plate 5.

[0023] Two sliders 11 are evenly threaded on the lower end surface of the arc plate 6. The vertical section of the slider 11 is in the shape of a "convex" character. Two slide grooves 12 are provided on the upper end surface of the base frame 3. The sliders 11 are inserted and slide in the slide grooves 12. The arc plate 6 is driven by the pushing cylinder 10 to move the arc plate 6 closer to or away from the base plate 5, and the sliders 11 slide in the slide grooves 12.

[0024] The base plate 5 is provided with a tear-edge groove 13 circumferentially. The vertical cross-section of the tear-edge groove 13 is semicircular, with the upper side of the tear-edge groove 13 adjacent to the upper end surface of the base plate 5. After the upper and lower molds 1 and 2 are pressed together and the shower base is formed, excess acrylic flows into the tear-edge groove 13. The excess material around the edge of the shower base is then removed through the tear-edge groove 13 of the base plate 5 to remove the shower base flash.

[0025] A through-hole is formed in the middle of the upper end surface of the base plate 5, into which a push rod 14 slides vertically. A push-out cylinder 15 is bolted to the lower end surface of the base frame 3, with the upper end of the output terminal of the push-out cylinder 15 fixed to the lower end of the push rod 14. Driven by the drive cylinder 9 and the push cylinder 10, the curved plate 6 and the two side plates 7 move away from the base plate 5, while the two side plates 7 rotate. The push-out cylinder 15 then pushes the push rod 14 upward, separating the shower basin from the base plate 5.

[0026] The upper end surfaces of the arc plate 6 and the two side plates 7 are respectively fixed with guide posts 16, and the lower end surface of the upper mold 1 is provided with three guide holes 17 for inserting the guide posts 16. Under the interaction between the guide posts 16 and the guide holes 17, the upper mold 1 and the lower mold 2 are accurately aligned.

[0027] The above description is only a preferred embodiment of the present invention. Therefore, any equivalent changes or modifications made according to the structure, features and principles described in the scope of the present invention patent application are included in the scope of the present invention patent application.
