It should be understood that the specific implementation described here is only used to illustrate and explain the present invention, and is not used to limit the present invention.

[0024] See also Figure 1 , Figure 1 It is a three-dimensional structural schematic diagram of a mold for processing plastic products provided by an embodiment of the utility model; Figure 2 It is a three-dimensional structural schematic diagram of a sliding component in a mold for processing plastic products provided by an embodiment of the utility model; Figure 3 It is a three-dimensional structural schematic diagram of a lower mold in a mold for processing plastic products provided by an embodiment of the utility model; Figure 4 The figure is a three-dimensional structural diagram of a plug-in board in a plastic product processing mold provided by an embodiment of the utility model. The plastic product processing mold 1 of the utility model comprises a bearing assembly, a sliding assembly 12 and a mold assembly 13. The bearing assembly comprises a bearing base 111, a bearing middle plate 112 and a guide column 113. The guide column 113 is fixed on the bearing base 111 so that the bearing middle plate 112 can slide along the guide column 113. The mold assembly 13 comprises an upper mold 131 and a lower mold 132. The upper mold 131 is mounted on the bearing middle plate 112. The sliding assembly 12 is slidably connected to the bearing base 111. The lower mold 132 is mounted on the sliding assembly 12.

[0025] By fixing the guide column 113 on the bearing base 111 and slidably connecting the bearing middle plate 112 to the guide column 113, the bearing middle plate 112 can slide along the guide column 113 relative to the bearing base 111. By fixing the upper mold 131 on the bearing middle plate 112 and slidably connecting the lower mold 132 to the bearing base 111 through the sliding assembly 12, the upper mold 131 can be driven to move synchronously with the movement of the bearing middle plate 112. After the sliding assembly 12 is slid onto the bearing base 111, the upper mold 131 can be covered on the lower mold 132, so that the operator can inject molten plastic material into the mold assembly 13 and obtain the desired plastic product after solidification.

[0026] After the plastic product solidifies in the mold assembly 13, the upper mold 131 and the lower mold 132 can be opened by moving the supporting middle plate 112. At this time, the plastic product adheres to the lower mold 132 under the action of gravity. The sliding assembly 12 is slid to make the lower mold 132 slide out from the supporting base 111. At this time, the lower mold 132 is inverted and knocked to make the plastic product fall off from the lower mold 132 under the action of gravity, thereby saving the cooling time of the plastic product and improving the processing efficiency of the plastic product.

[0027] In an embodiment of the utility model, the sliding assembly 12 includes a sliding base plate 121 and a support plate 122, the support plate 122 is fixed on both sides of the sliding base plate 121, connecting parts 123 are provided on both sides of the lower mold 132, and a connecting groove 124 adapted to the connecting part 123 is provided on the support plate 122 for connection with the lower mold 132.

[0028] By fixing the support plate 122 on both sides of the sliding base plate 121, a connecting groove 124 is opened on the support plate 122, and the connecting part 123 is set on both sides of the lower mold 132, so that the lower mold 132 is connected to the sliding base plate 121 through the connecting part 123 and the connecting groove 124, so that the lower mold 132 can slide or rotate along the sliding base plate 121 under the action of the connecting part 123. When the plastic product is completed and needs to be demolded, the sliding assembly 12 can be slid out of the supporting base 111, and the lower mold 132 can be slid out of the sliding base plate 121 or the lower mold 132 can be rotated, so that the operator can invert the lower mold 132 and make the plastic product in the lower mold 132 fall out of the lower mold 132.

[0029] In the embodiment of the present invention, the connecting portion 123 is an inserting block, the connecting groove 124 is a slot, and the lower mold 132 is inserted into the supporting plate 122 through the inserting block and the slot.

[0030] The connecting portion 123 is configured as an insert block, and the connecting groove 124 is configured as a slot, so that the lower mold 132 is connected to the support plate 122 by plugging and fitting the insert block and the slot. After the sliding assembly 12 is slid out of the supporting base 111, the lower mold 132 can be slid out of the sliding base plate 121 by sliding the lower mold 132, so that the operator can invert the lower mold 132 and make the plastic product in the lower mold 132 fall out of the lower mold 132, thereby improving the processing efficiency of the plastic products.

[0031] In the embodiment of the present invention, the connecting portion 123 is a rotating shaft, the connecting groove 124 is a plug hole, and the lower mold 132 is hinged to the support plate 122 via the rotating shaft and the plug hole.

[0032] By setting the connecting portion 123 as a rotating shaft and setting a socket in the connecting groove 124, the lower mold 132 can be connected to the support plate 122 through the rotational cooperation between the rotating shaft and the socket. Therefore, after the sliding assembly 12 is slid out from the supporting base 111, the operator can rotate the lower mold 132 to rotate the lower mold 132 around the rotating shaft, thereby inverting the lower mold 132 and causing the plastic product in the lower mold 132 to fall out of the lower mold 132, thereby improving the processing efficiency of the plastic products.

[0033] In an embodiment of the utility model, the sliding assembly 12 also includes a plug-in plate 125, and plug-in grooves 126 are provided on both sides of the plug-in plate 125. A plug-in block 127 aligned with the plug-in grooves is provided on the support plate 122. The plug-in plate 125 is plugged into the support plate 122 through the plug-in grooves 126 and the plug-in block 127, and the upper surface of the plug-in is in contact with the lower surface of the lower mold 132.

[0034] By providing plug-in slots 126 on both sides of the plug-in board 125 and providing plug-in blocks 127 on two sides of the support plate 122, the plug-in board 125 is plugged and connected with the plug-in blocks 127, so that the plug-in board 125 is fixed on the support plate 122 to support the lower mold 132. That is, since the lower mold 132 is connected to the support plate 122 in a hinged manner of a rotating shaft and a plug hole, in order to prevent the angle of the lower mold 132 on the support plate 122 from changing and causing defective plastic products to be produced during injection molding, the plug-in board 125 needs to be plugged into the support plate 122 so that the upper surface of the plug-in board 125 is in contact with the lower mold. The lower surface of the tool 132 is in contact with and forms a support for the lower mold 132 to prevent the lower mold 132 from rotating on the support plate 122 when the upper mold 131 is covered on the lower mold 132 for injection molding. When the injection molding of the plastic product is completed and the mold is opened, the plug-in plate 125 can be pulled out from the support plate 122 so that the lower mold 132 can be rotated under the hinge of the rotating shaft and the socket, so that the operator can rotate the lower mold 132 to make the plastic product fall out of the lower mold 132, thereby improving the demoulding efficiency of the plastic product, so as to use the mold assembly 13 for the next round of plastic processing operations and improve production efficiency.

[0035] In an embodiment of the utility model, a first magnetic member 1251 is disposed on the upper surface of the plug-in board 125 , and a second magnetic member is disposed on the lower surface of the lower mold 132 . When the plug-in board 125 is pulled out from the support plate 122 , the first magnetic member 1251 is attracted to the second magnetic member.

[0036] By arranging a first magnetic component 1251 on the upper surface of the plug board 125 and a second magnetic component on the lower surface of the lower mold 132, when the plug board 125 is pulled out from the support plate 122, the first magnetic component 1251 and the second magnetic component can be aligned and adsorbed to each other, and then when the plug board 125 is pulled out from the lower mold 132, the lower mold 132 can be driven to rotate around the rotating axis under the adsorption action of the first magnetic component 1251 and the second magnetic component, so that the operator can flip the already rotated lower mold 132 to pour out the plastic product in the lower mold 132, thereby improving the demolding efficiency of the plastic products.

[0037] In the above embodiment, the first magnetic component 1251 is arranged at the left side position of the plug board 125 in the Y-axis direction, and the second magnetic component is arranged at the right side position of the lower mold 132 in the Y-axis direction. When the plug board 125 is pulled out to the right along the support plate 122, the left side of the plug board 125 corresponds to the right side position of the lower mold 132, that is, the first magnetic component 1251 and the second magnetic component correspond in position and are attracted to each other, wherein the first magnetic component 1251 can be a magnetically attractable metal, and the second magnetic component can be a magnet, so that the magnet can attract the magnetically attractable metal.

[0038] In an embodiment of the utility model, the sliding assembly 12 also includes an insertion rod 128, one end of which is fixed with a handle 1281, and the other end is provided with a limiting boss 1282, and the plug-in plate 125 is provided with a plug-in hole for the insertion rod 128 to pass through, the length of the insertion rod 128 is greater than the width of the plug-in plate 125, and the length of the insertion rod 128 is less than the spacing of the guide columns 113.

[0039] By fixing the handle 1281 to one end of the plug rod 128 and the limit platform to the other end of the plug rod 128, the plug rod 128 can be inserted into the plug hole and prevented from detaching from the plug hole under the action of the limit boss 1282 and the handle 1281. Since the length of the plug rod 128 is greater than the width of the plug board 125 and the length of the plug rod 128 is less than the spacing of the guide posts 113, when the sliding component 12 is moved, the plug rod 128 can be inserted into the plug hole along the Y axis and the plug rod 128 can be located at the center of the spacing of the guide posts 113 to avoid the position of the plug rod 128 being too close to the edge and affecting the normal movement of the sliding component 12. After sliding out from the carrier base 111, the handle 1281 is pulled to facilitate the fit of the limiting boss 1282 and the plug-in board 125, and the handle 1281 is continued to be pulled to drive the plug-in board 125 to slide along the Y-axis on the support plate 122. When the plug-in board 125 slides out from the support plate 122, the first magnetic member 1251 and the second magnetic member are attracted to each other, and the plug-in board 125 moves downward under the action of gravity and drives the lower mold 132 to rotate around the rotating axis under the adsorption action of the first magnetic member 1251 and the second magnetic member, so that the operator can flip the already rotating lower mold 132 to pour out the plastic product in the lower mold 132, thereby improving the demolding efficiency of the plastic product.

[0040] In an embodiment of the utility model, positioning blocks 1283 are provided on both sides of the plug rod 128, and first slots 1253 are provided on the surfaces on both sides of the plug-in hole of the plug-in board 125, and a second slot for the positioning block 1283 to be rotatably engaged is provided on the inner wall of the plug-in hole, and the sizes of the first slot 1253 and the second slot are adapted to the positioning block 1283.

[0041] By providing positioning blocks 1283 on both sides of the plug rod 128, and opening a first slot 1253 matched with the positioning block 1283 on the surface of the plug board 125, and opening a second slot matched with the positioning block 1283 in the plug hole, it is convenient for the operator to pull the handle 1281 to drive the plug rod 128 to slide in the plug hole, so that the positioning block 1283 is inserted into the first slot 1253 or the second slot, thereby fixing the position of the plug rod 128. Specifically, when the handle 1281 is pushed and the positioning block 1283 on the right side is abutted against the second slot in the plug hole, the positioning block 1283 on the left side is moved out of the first slot 1253, and the positioning block 1283 can be engaged with the second slot by rotating the handle 1281, thereby preventing The stop rod 128 slides relative to the plug-in board 125. When the handle 1281 is pulled and the positioning block 1283 on the left side is abutted against the second slot in the plug-in hole, the positioning block 1283 on the right side is moved out of the first slot 1253. The positioning block 1283 can be engaged with the second slot by rotating the handle 1281, thereby preventing the plug-in rod 128 from sliding relative to the plug-in board 125. In this way, the position of the plug-in rod 128 is adjusted, so that when the positioning block 1283 on the right side is engaged in the second slot, the sliding assembly 12 can slide along the supporting base 111. When the positioning block 1283 on the left side is engaged in the second slot, the operator can pull the plug-in board 125 through the handle 1281 and drive the lower mold 132 to rotate, thereby improving the demolding efficiency of plastic products.

[0042] In an embodiment of the utility model, the supporting assembly also includes a supporting top plate 114 and a first driving member 115. The supporting top plate 114 is fixed to the top of the guide column 113. The first driving member 115 is fixed to the supporting top plate 114 and connected to the supporting middle plate 112 to drive the supporting middle plate 112 to move along the guide column 113.

[0043] By setting a bearing top plate 114 on the top of the guide column 113 and fixing the first driving member 115 on the bearing top plate 114, the first driving member 115 is connected to the bearing middle plate 112, and then the bearing middle plate 112 can be driven to move along the guide column 113 under the action of the first driving member 115, so as to drive the upper mold 131 and the lower mold 132 to cover when the plastic product is injected, and drive the upper mold 131 and the lower mold 132 to open the mold after the injection molding is completed, so as to realize the automatic operation of covering and opening the mold assembly 13, thereby improving the processing efficiency of the plastic product, wherein the first driving member 115 includes any one of a cylinder, a hydraulic cylinder, and an electric cylinder.

[0044] See also Figure 2In an embodiment of the utility model, a slide rail 1111 is arranged on the supporting base 111, a slide groove aligned with the slide rail 1111 is opened on the sliding base plate 121, and a limit block 1112 and a limit plate 1113 are respectively arranged on both sides of the slide rail 1111 to limit the sliding distance of the sliding base plate 121. The sliding assembly 12 also includes a second driving member 129, which is fixed on the limit plate 1113 and connected to the support plate 122 to drive the sliding base plate to slide along the slide rail 1111.

[0045] By arranging a slide rail 1111 on the carrying base 111 and opening a slide groove on the sliding base plate 121, the sliding base plate 121 can slide relative to the carrying base 111 along the slide rail 1111, that is, the sliding base plate 121 moves along the X-axis on the slide rail 1111, thereby driving the lower mold 132 to move along the X-axis, so that when the sliding base plate 121 slides into the carrying base 111 and the lower mold 132 is aligned with the upper mold 131, the lower mold 132 is driven to descend by the first driving member 115, that is, the first lower mold 132 moves downward along the Z-axis to cover the mold assembly 13, so as to facilitate the injection molding operation of the mold assembly 13, and when the sliding assembly 12 slides out from the sliding base plate 121, it is convenient for the operator to flip the lower mold 132 to facilitate the plastic product to fall out of the lower mold 132.

[0046] By respectively arranging a limit block 1112 and a limit plate 1113 on both sides of the slide rail 1111, the sliding distance of the sliding base plate 121 is limited under the action of the limit block 1112 and the limit plate 1113. When the sliding base plate 121 is in contact with the limit block 1112, the lower mold 132 is aligned with the upper mold 131. At this time, the lower mold 132 is driven down by the first driving member 115 so that the upper mold 131 can cover the lower mold 132.

[0047] By arranging a second driving member 129 on the limiting plate 1113 and connecting the second driving member 129 to the support plate 122, the sliding base plate 121 is driven to slide along the slide rail 1111 under the action of the second driving member 129. When the sliding base plate 121 slides to the rightmost side, the sliding base plate 121 fits with the limiting block 1112. When the sliding assembly 12 slides to the leftmost side, the sliding base plate 121 fits with the limiting plate 1113, thereby realizing the automatic movement of the sliding base plate 121, which is convenient for improving the processing efficiency of plastic products.
