Description

Technical Field

[0001] This utility model relates to the field of composite molding die technology, specifically a multi-layer composite molding die for the production of wear-resistant PVC gloves. Background Technology

[0002] Abrasion-resistant PVC gloves are gloves with a knitted cotton, chemical fiber, or blended fabric lining, coated with polyvinyl chloride (PVC) material on the outer layer, and specially treated to enhance their abrasion resistance. In the production process of abrasion-resistant PVC gloves, multi-layer composite molding molds are usually used to assist in the production. A multi-layer composite molding mold is a specially designed mold that can integrate two or more materials with different properties (such as plastics of different colors, plastics with different functions, plastics and fabrics, plastics and metals, etc.) into a complete part in one clamping and one molding cycle.

[0003] In traditional multi-layer composite molding dies, the connection between the lower die and the base is usually achieved through welding or other fixing methods. This makes changing the lower die to a different type relatively cumbersome and inconvenient. While this fixing method ensures the stability and durability of the die to some extent, its inconvenience becomes apparent when changing the die according to different production needs or product specifications. Welding or other fixing methods require specialized tools and operators for disassembly and reinstallation, which is time-consuming and hinders the rapid disassembly and replacement of the lower die. Utility Model Content

[0006] As a further preferred embodiment of this technical solution, a driving cylinder is fixedly connected to the top of the top plate, and an upper mold is fixedly connected to the bottom of the driving cylinder.

[0007] As a further preferred embodiment of this technical solution, the inner wall of the slot is provided with a movable groove, the inner wall of the movable groove is slidably connected with a positioning block, and the inner wall of the movable groove is fixedly connected with a spring.

[0008] As a further preferred embodiment of this technical solution, the end of the spring away from the inner wall of the movable groove is fixedly connected to the outer wall of the positioning block, and the end of the positioning block near the spring is fixedly connected to a connecting rod. The connecting rod passes through and is slidably connected to the inner wall of the movable groove, and a pull ring is rotatably connected to the outer wall of the connecting rod.

[0009] As a further preferred embodiment of this technical solution, the receiving plate is provided with an ejection mechanism inside, and a cavity is opened at the top of the receiving plate.

[0010] As a further preferred embodiment of this technical solution, the lower mold has an ejector groove at its inner bottom end, a lead screw is rotatably connected to the inner bottom end of the cavity, an ejector plate is threadedly connected to the outer wall of the lead screw, and the ejector plate is slidably connected to the inner wall of the ejector groove.

[0011] As a further preferred embodiment of this technical solution, a worm is rotatably connected through the inner wall of the cavity, and a worm wheel is fixedly connected to the outer wall of the lead screw, with the worm and the worm wheel being threadedly connected.

[0012] This utility model provides a multi-layer composite molding die for producing wear-resistant PVC gloves, which has the following advantages: (1) This utility model uses a flip-up pull ring to pull the pull ring outward. The pull ring drives the connecting rod to move outward. The moving connecting rod drives the positioning block to move inside the movable groove until the positioning block is disengaged from the inside of the positioning groove. At this time, the insert block is disengaged from the positioning, and the lower mold moves upward. The lower mold drives the insert block to disengage from the inside of the slot. When the lower mold is replaced, the insert block is inserted into the inside of the slot. The insert block presses against the positioning block. The positioning block is pressed and moves inside the movable groove and presses against the spring until the insert block is completely inserted into the inside of the slot. The spring is not affected by external force and uses its own elasticity to drive the positioning block to reset. The positioning block is reinserted into the inside of the positioning groove to fix the lower mold. (2) This utility model rotates the worm, which drives the worm wheel, which in turn drives the lead screw, which in turn drives the ejector plate to move upward. The ejector plate moves inside the ejector groove to eject the produced material, making it easier for workers to pick up the material. Attached Figure Description

A positioning groove 83 is provided on the outer wall of the insert block 82.

[0017] The top plate 3 is fixedly connected to the top end of the drive cylinder 4, and the bottom end of the drive cylinder 4 is fixedly connected to the upper mold 5.

[0018] By driving cylinder 4, the upper mold 5 can be moved up and down vertically.

[0019] The inner wall of the slot 81 is provided with a movable groove 84, a positioning block 85 is slidably connected to the inner wall of the movable groove 84, and a spring 86 is fixedly connected to the inner wall of the movable groove 84.

[0020] The movement trajectory of the positioning block 85 can be restricted by the movable slot 84.

[0021] The end of the spring 86 away from the inner wall of the movable groove 84 is fixedly connected to the outer wall of the positioning block 85. The end of the positioning block 85 near the spring 86 is fixedly connected to a connecting rod 87. The connecting rod 87 passes through and is slidably connected to the inner wall of the movable groove 84. A pull ring 88 is rotatably connected to the outer wall of the connecting rod 87.

[0022] The movement of the connecting rod 87 can drive the positioning block 85 to move.

[0023] The receiving plate 6 has an ejection mechanism 9 inside, and a cavity 91 is opened at the top of the receiving plate 6.

[0024] The ejector mechanism 9 can eject the completed material.

[0025] The lower mold 7 has an ejector groove 95 at its inner bottom end, and a lead screw 92 is rotatably connected to the inner bottom end of the cavity 91. An ejector plate 96 is threadedly connected to the outer wall of the lead screw 92, and the ejector plate 96 is slidably connected to the inner wall of the ejector groove 95.

[0026] The lead screw 92, when rotated, can drive the ejector plate 96 to move vertically up and down.
