The workpiece 100 is arranged in a hollow structure. Two functional holes 101 are arranged on the workpiece 100. The two functional holes 101 are arranged opposite to each other in the horizontal direction. The mold with a lateral demolding structure includes an upper mold 10 and a lower mold 20 opposite to the upper mold 10. The upper mold 10 and the lower mold 20 together form a mold cavity for molding the workpiece 100.

[0024] The upper mold 10 includes a fixed plate 11, a positioning plate 12 arranged below the fixed plate 11, an upper mold core 16 installed on the positioning plate 12, two sliders 14 slidably arranged on the positioning plate 12 and arranged opposite to each other, a functional rod 15 installed on the slider 14, and a driving block 13 installed on the fixed plate 11. The upper mold core 16 is provided with a plurality of upper mold cavities 161. The functional rods 15 are grouped into two, and the two functional rods 15 in the same group correspond to one upper mold cavity 161. The driving block 13 passes through the positioning plate 12 and is installed in cooperation with the slider 14. When the fixed plate 11 is displaced in the vertical direction relative to the slider 14, the two driving blocks 13 installed on the fixed plate 11 respectively drive the two sliders 14 to shift synchronously in the opposite direction. During the displacement process, the two sliders 14 drive the two functional rods 15 to extend into the upper mold cavity 161 or withdraw from the upper mold cavity 161.

[0025] Specifically, the driving block 13 includes a connecting section 131 and a guide section 132 connected to one end of the connecting section 131. The end of the connecting section 131 away from the guide section 132 is fixedly mounted on the fixed plate 11, and the connecting section 131 extends into the positioning plate 12. The guide section 132 is inclined toward the outside, and the guide sections 132 of the two driving blocks 13 are arranged in opposite directions.

[0026] The slider 14 includes a main body 141 and guide edges 142 connected to both sides of the main body 141 . The main body 141 is provided with an inclined guide hole 143 . The inclined guide hole 143 penetrates the main body 141 along an inclined direction, and the inclined angle of the inclined guide hole 143 is consistent with the guide section 132 of the driving block 13 .

[0027] The positioning plate 12 has two sides with slide grooves 121 extending inward from both sides of the positioning plate 12. The grooves 121 are T-shaped and correspond to the cross section of the slider 14. The positioning plate 12 is also provided with a plurality of through holes, which connect the slide grooves 121 with the upper mold cavity 161.

[0028] During assembly, the slider 14 is installed in the slide groove 121 through the guide edge 142, and the slider 14 can move horizontally in the slide groove 121. One end of the functional rod 15 is installed on the slider 14, and the other end of the functional rod 15 is inserted into the through hole. The guide section 132 of the driving block 13 extends into the oblique guide hole 143. In addition, the demolding mold further includes a first driving device and a second driving device. The first driving device drives the fixing plate 11 to adjust in the vertical direction alone, and the second driving device drives the first driving device and the positioning plate 12 to adjust synchronously.

[0029] The lower mold 20 includes a bottom plate 21 , a support plate 22 mounted on the bottom plate 21 , a lower mold plate 23 mounted on the support plate 22 , and a lower mold core 24 mounted on the lower mold plate 23 . A mold protrusion 241 is provided on the lower mold core 24 .

[0030] When the mold is closed, the second driving device drives the positioning plate 12 to press down, and the first driving device drives the fixed plate 11 to press down, so that the upper mold core 16 of the upper mold 10 and the lower mold core 24 of the lower mold 20 are in a closed mold state, and the mold protrusion 241 and the upper mold cavity 161 are combined to form a film cavity for molding products. During the process of the first driving device driving the fixed plate 11 to press down, the two driving blocks 13 installed on the fixed plate 11 press the hole wall of the inclined guide hole 143 inward, and then drive the two sliders 14 to shift inward respectively. During the shifting process, the two sliders 14 drive the two functional rods 15 to extend into the upper mold cavity 161. The workpiece 100 is injection molded into the mold cavity, wherein the functional rod 15 extending into the upper mold cavity 161 is used to mold the functional hole 101 on the workpiece 100.

[0031] When the mold is opened, the first driving device drives the fixed plate 11 to lift up. During the lifting process of the fixed plate 11, the two driving blocks 13 installed on the fixed plate 11 squeeze the hole wall of the inclined guide hole 143 outward, and then drive the two sliders 14 to shift outward respectively. During the shifting process, the two sliders 14 drive the two functional rods 15 to withdraw from the upper mold cavity 161. The second driving device drives the positioning plate 12 and the first driving device to lift up, and the upper mold core 16 and the fixed plate 11 are lifted up synchronously.

[0032] The beneficial effect of the mold with a lateral demolding structure of the utility model is that: a slider 14 slidably mounted on the positioning plate 12 is arranged on the upper mold 10, a functional rod 15 is installed on the slider 14, and a driving block 13 mounted on the fixed plate 11 is also arranged on the upper mold 10. When opening the mold, the guide section 132 of the driving block 13 cooperates with the inclined guide hole 143 of the slider 14, and the two driving blocks 13 installed on the fixed plate 11 respectively drive the two sliders 14 to shift synchronously in opposite directions. During the shifting process, the two sliders 14 drive the two functional rods 15 to withdraw from the upper mold cavity 161. The overall structure is simple, the mold cost is reduced, and rapid mold opening can be achieved, effectively improving the mold opening efficiency.

To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0034] The above-mentioned embodiments only express several implementation methods of the utility model, and the description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
