[0002] The mold ejector is a common component used in mold processing. It is suitable for ejecting the molded products in the mold. The mold ejector is installed in the mold ejector mounting hole in the mold. When the molded product needs to be ejected, the ejector rod of the mold ejector extends from the mounting hole to complete the ejection of the molded product.
[0003] When using the mold ejector, the staff needs to insert the mold ejector into the reserved hole of the mold. Since some molds require a large number of ejectors, the staff needs to insert multiple ejectors. Due to the large number of ejectors, inserting the ejectors takes a lot of time. In addition, during this process, the staff needs to pick up and put down the ejector back and forth, and the sharp part of the ejector may cause damage to the staff's hands.
[0004] To this end, we provide a mold ejector with a replaceable needle core to solve the above problems. Utility Model Content

[0030] Specifically: the staff pulls the limit plate 4 to the right to separate the limit plate 4 from the bottom plate 1, and then removes the limit shell 205 from the limit block 204. When the limit block 204 is separated from the limit shell 205, the staff will take out all the first mounting plate 201 and the second mounting plate 202 except the first mounting plate 201 on the far left, and then the staff will place the mold ejector pins to be installed in sequence into the mounting groove of the first mounting plate 201 through the transverse groove opened on the top of the bottom plate 1. At this time The staff pushes the second mounting plate 202 into the inner cavity of the base plate 1 in conjunction with the second fixing plate 207 and the positioning rod 6. When the first second fixing plate 207 contacts the first fixing plate 203 on the far left, the limiting shell 205 is inserted into the inner cavity of the two limiting blocks 204 again, thereby completing the rapid installation of the single-row mold ejector pins. Subsequently, the staff pushes the first mounting plate 201 and the second mounting plate 202 into the inner cavity of the base plate 1 in turn in the above manner, and finally merges the limiting plate 4 with the base plate 1 again. Specific embodiment 2
[0032] See also Figure 1-6 On the basis of the specific embodiment 1, the first fixed plate 203 and the second fixed plate 207 are fixedly connected to the limiting block 204 on the side away from the positioning rod 6, and the limiting shell 205 is inserted between the inner cavities of each two limiting blocks 204. The inner cavities of the first fixed plate 203 and the second fixed plate 207 are fixedly connected to two clamping blocks 206, and the surface of the clamping block 206 is slidably connected to the inner cavity of the positioning rod 6.
[0033] Specifically: by setting the limit block 204 and the limit shell 205 for use together, the stability of the first mounting plate 201 and the second mounting plate 202 can be ensured when the user splices the first mounting plate 201 and the second mounting plate 202 through the first fixing plate 203 and the second fixing plate 207. By setting the clamping block 206, a limiting function is played on the first fixing plate 203 and the second fixing plate 207 on the positioning rod 6. Specific embodiment three
[0035] See also Figure 1-6 On the basis of the specific embodiment 1 and the specific embodiment 2, positioning grooves 5 are provided on the front and rear sides of the bottom right side of the bottom plate 1, and a positioning block 7 is clamped in the inner cavity of the positioning groove 5. The right side of the positioning block 7 is fixedly connected to the limit plate 4. The first mounting plate 201 on the left side of the nine first mounting plates 201 is different in shape from the other eight. The left side of the first mounting plate 201 on the left side is fixedly connected to the inner wall of the bottom plate 1. The number of mounting grooves provided on the first mounting plate 201 and the second mounting plate 202 is several, and the number of top and transverse grooves of the bottom plate 1 is several.
[0036] Specifically: by setting the positioning groove 5 and the positioning block 7 for use together, the limit plate 4 is prevented from falling off the base plate 1 during use. The leftmost first mounting plate 201 is used for positioning, which is convenient for splicing the remaining first mounting plates 201 and second mounting plates 202. The mounting grooves on the first mounting plates 201 and the second mounting plates 202 are used in conjunction with the transverse grooves on the top of the base plate 1, which is convenient for the staff to install different numbers of mold ejectors.
[0037] The working principle of the utility model is as follows: the staff pulls the limit plate 4 to the right to separate the limit plate 4 from the bottom plate 1, and then removes the limit shell 205 from the limit block 204. When the limit block 204 and the limit shell 205 are completely separated, the staff will take out all the first mounting plate 201 and the second mounting plate 202 except the first mounting plate 201 on the far left, and then the staff will place the mold ejector pins to be installed into the mounting groove of the first mounting plate 201 in sequence through the transverse groove opened on the top of the bottom plate 1. At this time, the staff pushes the second mounting plate 202 into the inner cavity of the bottom plate 1 in conjunction with the second fixing plate 207 and the positioning rod 6. When the first second fixing plate 207 contacts the first fixing plate 203 on the far left, the limiting shell 205 is inserted into the inner cavity of the two limiting blocks 204 again, thereby completing the rapid installation of the single-row mold ejector pins. Subsequently, the staff pushes the first mounting plate 201 and the second mounting plate 202 into the inner cavity of the bottom plate 1 in turn in the above manner, and finally merges the limiting plate 4 with the bottom plate 1 again.
