Technical Field

[0001] The utility model relates to the technical field of injection molding, in particular to a production device for door skin products for injection molding. Background Art

[0002] Door skin usually refers to the covering or protective layer on the surface of the door body. It can be made of a variety of materials. Depending on the type and purpose of the door, the material of the door skin will also vary. Some plastic door skins need to be processed with the help of injection molds during production.

[0003] Due to the large specifications of the door skin, when it is molded through the injection mold, the operator is required to reach into the injection molding machine to take out the molded door skin. When the operator is not required to take the workpiece, the door skin will be pushed out by the push plate and push rod and other components inside the injection mold. The pushed out door skin will fall directly and come into contact with the ground inside the injection molding machine, making the surface of the door skin susceptible to friction damage, thereby reducing the production molding quality of the door skin.

[0004] Therefore, we proposed a production device for injection molding door skin products to solve the above problems. Utility Model Content

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model embodiment discloses a device for producing a door skin product for injection molding.

[0026] Example 1

[0027] The utility model provides Figure 1-3 The production device for injection molding door skin products shown includes an upper mold 1 and a lower mold 2. A molding template 3 is fixedly provided at the bottom of the upper mold 1. A groove is opened at the top of the lower mold 2. A molding cavity 4 is arranged in the groove. The molding template 3 is plugged into and matched with the inside of the molding cavity 4. A stopper 18 is fixedly provided at the bottom of the upper mold 1. The stopper 18 is arranged in cooperation with the groove. A strip hole is opened at the lower end of the inner part of the lower mold 2. A reciprocating screw rod 5 is rotatably arranged inside the strip hole. A slider 6 is threadedly sleeved on the rod wall of the reciprocating screw rod 5. A pushing block 7 is contacted with the inner wall of the groove. A mounting plate 9 is fixedly provided on the side close to the pushing block 7 and the molding cavity 4. A connecting bolt 10 and a nut 11 are threadedly provided between the two mounting plates 9. A connecting rod 8 is fixedly provided between the slider 6 and the pushing block 7. The connecting rod 8 is a U-shaped rod. A sliding hole for matching the sliding of the connecting rod 8 is opened on the rear side of the groove. The rear side of the mounting plate 9 is slidably arranged in the sliding hole.

[0028] Before preparing the door skin, the upper mold 1 and the lower mold 2 are connected so that the molding template 3 is inserted into the molding cavity 4, and the stopper 18 is inserted into the groove to determine the position of the molding cavity 4, and then the molten injection plastic is injected into the molding cavity 4 to complete the molding of the door skin. After the door skin is molded, the upper mold 1 and the lower mold 2 are separated. At this time, the reciprocating screw 5 rotates to drive the slider 6 to move horizontally. Under the connection of the connecting rod 8, the pushing block 7 moves synchronously with the slider 6 to push the molding cavity 4, so that the molding cavity 4 is pushed out from between the upper and lower molds and out of the injection molding machine, so that the operator can take the door skin inside the molding cavity 4 from the outside of the injection molding machine, while improving the safety of the door skin material collection, trying to avoid the door skin from contacting with the outside and causing surface wear, thereby improving the preparation efficiency of the door skin. After the door skin is taken out, the reciprocating screw 5 continues to rotate to move the molding cavity 4 back to the groove again, which is convenient for subsequent door skin molding work.

[0029] Example 2

[0030] Embodiment 2 is based on Embodiment 1 in order to be able to drive the reciprocating screw 2 to rotate continuously and stably after the upper die 1 and the lower die 2 are separated. Figure 1-2 As shown, a pushing mechanism for driving the pushing block 7 to move horizontally is provided between the upper mold 1 and the reciprocating screw 5, and the pushing mechanism includes a vertical plate 12, which is fixedly connected to the bottom of the upper mold 1, and a plurality of spaced connecting blocks 13 are fixedly provided on the outer wall of the vertical plate 12, and a ratchet 14 is rotatably provided at the end of the connecting block 13, and a spring 15 is fixedly provided between the ratchet 14 and the vertical plate 12, and a limit plate 16 is provided at the bottom of the ratchet 14, and the limit plate 16 is fixedly connected to the vertical plate 12, and a ratchet 17 is fixedly provided on the rod wall of the reciprocating screw 5, and the ratchet 17 is matched with the plurality of ratchet teeth 14.

[0031] After the upper mold 1 and the lower mold 2 are separated, the vertical plate 12 drives the multiple ratchets 14 to move, and the ratchets 14 cannot rotate due to the support of the limit plate 16. At this time, the multiple ratchets 14 can push the ratchet 17, so that the ratchet 17 drives the reciprocating screw 5 to rotate, so that the reciprocating screw 5 can drive the molding cavity 4 to move horizontally and disassemble the door skin. Before the door skin is prepared, the upper mold 1 is close to the lower mold 1. At this time, the multiple ratchets 14 can rotate around the end of the connecting block 13 after contacting the ratchet 17, and squeeze the spring 15, so that the ratchets 14 cannot push the ratchet 17, and the reciprocating screw 5 cannot rotate. At this time, the molding cavity 4 can be stably set in the groove and cooperate with the molding template 3 to carry out the molding production of the door skin.

[0032] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
