Description

Technical Field

[0001] The invention relates to the field of injection molding, and in particular to a multifunctional cable injection molding device. Background Art

[0002] During the process of plug injection molding, the cable needs to be manually loaded and demolded. When demolding a two-pin plug, because the cable of the two-pin plug is parallel to the two contact pins of the plug, workers usually only need to hold the cable and then pull out the plug, which is more convenient. However, when demolding a triangular plug, because the cable of the triangular plug is 90° vertical to the three antennae of the plug, workers cannot easily pull out the plug by pulling the cable. At the same time, after the cable plug is injection molded, the plug is relatively soft. If it is forcibly pulled out, the plug is easily deformed by pressure, resulting in distortion of the plug after cooling and molding, affecting the injection molding quality.

[0003] At the same time, after the injection molding is completed, the existing injection molding machine requires workers to take out the lower mold, and then install the new lower mold with the cables plugged in before injection molding. This is more troublesome, cannot be operated continuously, and has low efficiency. Summary of the invention

[0039] A friction block 113 is also included; a friction block 113 is fixedly connected to the middle part of the lower side of each wire drawing plate 111 .

[0040] The lower side of the sponge block 112 and the lower side of the friction block 113 are both inclined from the upper rear part to the lower front part.

[0041] The working principle of the above embodiment is as follows:

[0042] First, the worker inserts the triangular plug cable 555 into the mold slot 5001. Figure 1As shown, in the initial state, the base 3 and the lower mold 5 on the right are located directly below the upper mold 4. After the triangular plug cable 555 is placed, the worker starts the injection molding machine 2, and then the upper mold 4 slowly descends and closes with the lower mold 5 on the right, and then injects into the mold groove 5001 through the injection port 4001 to complete the injection molding of the triangular plug cable 555. After the injection molding is completed, the upper mold 4 rises and resets. At this time, the two bases 3 are driven to move to the right on the slide rail 101 by the electric slider 102, and the base 3 and the lower mold 5 on the left are brought to the bottom of the upper mold 4, and then the upper mold 4 descends again and closes with the lower mold 5 on the left for injection molding. During this process, the worker can remove the triangular plug cable 555 that has been injected on the right lower mold 5 and replace it with a new triangular plug cable 555 that needs to be injected; after the replacement is completed, the triangular plug cable 555 on the left lower mold 5 The plug cable 555 is also injection molded, and at this time, the two bases 3 are driven to move to the left through the electric slider 102, and the base 3 on the right and the lower mold 5 are brought to the bottom of the upper mold 4 for mold closing and injection molding. Through this method, the injection molding machine 2 can operate uninterruptedly, which greatly improves the work efficiency. In order to ensure the injection molding effect of each triangular plug cable 555, a connecting groove 5002 is provided on the upper surface of the lower mold 5, and each mold groove 5001 is connected to each other through the connecting groove 5002. Therefore, when individual injection ports 4001 are blocked and the injection molding effect is poor, after the remaining injection ports 4001 complete the injection molding of the corresponding mold groove 5001, the excess injection liquid can be injected into other mold grooves 5001 through the connecting groove 5002, thereby ensuring the injection molding effect of the triangular plug cable 555 in each mold groove 5001.

[0043] However, when demolding the triangular plug cable 555, the worker cannot easily pull out the triangular plug cable 555 by pulling out the cable because the three antennae of the triangular plug cable 555 and the plug are at a 90° vertical state. At the same time, the cable plug is relatively soft after the injection molding is completed. If it is forcibly pulled out, the plug is easily deformed by pressure, resulting in the distortion of the plug after cooling and molding, affecting the injection molding quality. Figure 4 As shown: in the initial state: the pressure plate 105 is located at the top of the first cavity 3001, and the first spring 106 is squeezed by the pressure plate 105 into a compressed state. When the worker puts the triangular plug cable 555 into the mold groove 5001, the three tentacles of the triangular plug cable 555 will be inserted into the magnetic suction groove 10501 correspondingly opened above the pressure plate 105, and will be attracted by the weak magnetic block of the magnetic suction groove 10501. However, at this time, the triangular plug cable 555 is blocked by the pressure plate 105, and does not completely enter the mold groove 5001; therefore, it will seriously affect the subsequent injection molding;

[0044] However, during the process of the upper mold 4 descending and closing with the lower mold 5, the upper mold 4 will first contact with the pressure plate 105 and press the pressure plate 105 downward. At this time, the first spring 106 is further compressed, and the triangular plug cable 555 is adsorbed by the pressure plate 105 and then moves downward with the pressure plate 105, and then completely enters the mold groove 5001. After the upper mold 4 and the lower mold 5 are closed, the triangular plug cable 555 in the mold groove 5001 is injection molded through the injection port 4001 to ensure the injection molding effect. After the molding is completed, the upper mold 4 moves upward and resets to release the squeeze on the pressure plate 105. At this time, the first spring 106 stretches and resets, thereby driving the pressure plate 105 to move upward and reset, thereby squeezing the injection-molded triangular plug cable 555 upward, and pushing up the three antennae of the triangular plug cable 555, so that the triangular plug cable 555 becomes relatively loose, which is convenient for workers to pull out the triangular plug cable 555; avoid forcible pulling out, which causes the plug of the triangular plug cable 555 to be compressed and deformed, affecting the injection molding quality;

[0045] At the same time, after the worker has placed the triangular plug cable 555, he can clip the front end of the cable into the limiting groove 10301. During this process, the rubber clamping block 104 will shrink and deform due to compression, which makes it easier for the worker to insert. However, after the triangular plug cable 555 is inserted into the limiting groove 10301, the clamping block 104 is reset, thereby clamping the front end of the triangular plug cable 555 to prevent the triangular plug cable 555 from falling off during the left and right movement of the base 3 and the lower mold 5. However, although the injection molding effect of each triangular plug cable 555 is improved by the connecting groove 5002, excess scraps will be generated in the connecting groove 5002 after the injection molding is completed. When the worker is removing the scraps, because the triangular plug cable 555 is still relatively soft when the injection molding is completed, the plastic around the contact point is easily brought out during the removal process, causing the triangular plug cable 555 to deform and affect the quality. Figure 5 and Figure 6As shown, in the process of the upper mold 4 moving downward to complete the mold closing with the lower mold 5, the cutter 108 will first contact the lower mold 5, and as the upper mold 4 moves downward, the second spring 109 will be compressed and contracted, thereby driving the cutter 108 to move into the upper mold 4; when the upper mold 4 and the lower mold 5 complete the mold closing, the cutter 108 is also completely contracted to the corresponding groove on the lower side of the upper mold 4, and when the upper mold 4 moves upward to reset, the upper mold 4 gradually releases the squeeze on the pressure plate 105; the pressure plate 105 gradually moves upward to reset The triangular plug cable 555 is pushed upward, but when the upper mold 4 moves upward and resets, the second spring 109 also gradually stretches and resets. Therefore, at this time, the cutter 108 is squeezed by the second spring 109 and is always in contact with the lower mold 5. Therefore, when the triangular plug cable 555 moves upward, the remaining material in the connecting groove 5002 cannot move upward and is cut by the cutter 108. Then, when the upper mold 4 moves upward and resets, the remaining material in the connecting groove 5002 is separated, thereby preventing subsequent workers from damaging the triangular plug cable 555 when pulling out the remaining material.

[0046] At the same time, the main purpose of injection molding the triangular plug cable 555 is to wrap the exposed cable of the triangular plug cable 555 plug, but the exposed cable at the plug usually has a margin, which makes the cable bulge upward, resulting in the inability to completely wrap the exposed cable at the plug position after injection molding. Therefore, in the process of closing the upper mold 4 and the lower mold 5, at the same time, because the lower side of the sponge block 112 and the lower side of the friction block 113 are inclined from the upper part of the rear side to the lower part of the front side; therefore, as the upper mold 4 continues to move downward, the wire drawing plate 111 located at the front side of the through groove 5003 will first contact with the wire drawing plate 111 located at the through groove 5003. 3, the triangular plug cable 555 on the front side is in contact, and the lower side of the wire drawing plate 111 is open, so that the triangular plug cable 555 deviating from the through groove 5003 can be moved to the middle and guided, and the friction between the wire drawing plate 111 and the triangular plug cable 555 is increased by the friction block 113 made of rubber material; and after the wire drawing plate 111 contacts the triangular plug cable 555, the sealing block 110 also enters the through groove 5003, at this time, the sealing block 110 is stuck at the through groove 5003 and cannot move forward and backward, and at this time, the sponge block 112 contacts the triangular plug cable 555 ; The downward movement of the wire-smoothing plate 111 can drag the triangular plug cable 555 toward the lower front side. At the same time, the electric push rod 118 is pushed forward during this process, thereby driving the wire-smoothing plate 111 to move toward the front side. At this time, the third spring 115 is stretched by tension, and the slide bar 114 slides forward in the slide groove 11001, and then the triangular plug cable 555 is further dragged toward the lower front side through the wire-smoothing plate 111, and the exposed cable protruding upward in the mold groove 5001 is dragged toward the lower front side and straightened; but as the upper mold 4 continues to move downward, the sponge block 112 is compressed, and the sponge block 112 is pressed against the The clamping force of the triangular plug cable 555 gradually increases. After the sponge block 112 is compressed to the extreme, the upper mold 4 and the lower mold 5 are molded together, and the electric push rod 118 stops extending. At this time, the triangular plug cable 555 cannot be dragged to the lower front side, and the sealing block 110 also completely blocks the through groove 5003 to prevent the injection liquid from overflowing from the through groove 5003. It should be noted that the cable wrapped with the shell on the front side of the triangular plug cable 555 will not be completely pulled out of the mold groove 5001; and in the process of the wire drawing plate 111 pulling and straightening the exposed cable in the mold groove 5001, if Figure 6As shown, in the initial state: the third spring 115 is in a contracted state, at this time the slide bar 114 is completely located in the slide groove 11001, the wire drawing plate 111 and the sealing block 110 are in a fitted state, and at the same time the folding fan baffle 117 protrudes from the rear side of the sealing block 110 and is in an open state. At the same time, because the folding fan baffle 117 and the connecting block 116 are connected by a torsion spring, the folding fan baffle 117 will naturally twist downward; and at this time the folding fan baffle 117 is just located above the mold groove 5001, so in the process of the upper mold 4 moving downward, when the friction block 113 on the lower side of the wire drawing plate 111 contacts the triangular plug cable 555, the folding fan baffle 117 also squeezes downward with the upward protruding exposed cable in the mold groove 5001, and at the same time, the exposed cable in the mold groove 5001 is pushed toward the through groove 5001 through the downward twisted folding fan baffle 117. 03 direction extrusion, improve the pulling and straightening effect of the wire drawing plate 111 on the triangular plug cable 555, and when the wire drawing plate 111 is pressed and moves forward, the slide bar 114 moves forward, thereby driving the connecting block 116 and the folding fan baffle 117 to move forward. At this time, the folding fan baffle 117 contacts the sealing block 110, slowly retracts, and moves forward to the slide groove 11001 to avoid affecting the subsequent injection molding. After the injection molding is completed, the upper mold 4 moves upward and resets. At this time, the wire drawing plate 111 is separated from the triangular plug cable 555, and the wire drawing plate 111 releases the stretching of the third spring 115. The third spring 115 shrinks and resets, and the slide bar 114 moves backward and resets in the slide groove 11001, thereby driving the wire drawing plate 111 to reset, and at the same time pushes the folding fan baffle 117 backward to reset, and then the folding fan baffle 117 is unfolded again.

[0047] According to the above working principle, we know that the present invention has the following effects:

[0048] The two bases 3 and the lower mold 5 are driven to move left and right by the sliding assembly. When one of the lower molds 5 is performing injection molding, the worker can replace the triangular plug cable 555 in the other lower mold 5. The worker does not need to dismantle or install the lower mold 5, so that the upper mold 4 can perform mold closing and injection molding work uninterruptedly, which greatly improves the work efficiency.

[0049] When the upper mold 4 is moved upward and reset, the pressure plate 105 is released from the pressure plate 105. At this time, the first spring 106 is extended and reset, thereby driving the pressure plate 105 to move upward and reset, thereby squeezing the triangular plug cable 555 upward, so that the triangular plug cable 555 is in a loose state, which is convenient for workers to pull out the triangular plug cable 555. It is avoided that the plug of the triangular plug cable 555 is compressed and deformed by forced pulling out, which affects the injection molding quality.

[0050] Through the wire-smoothing plate 111 and the sponge block 112 and the friction block 113 which are tilted from the upper rear side to the lower front side, the exposed cables protruding upward in the mold groove 5001 are dragged toward the lower front side of the mold groove 5001 before the upper mold 4 and the lower mold 5 are closed; and then the exposed cables protruding in the mold groove 5001 are straightened to prevent the cables in the mold groove 5001 from protruding upward, resulting in the failure of injection molding to completely wrap the cables; and in this process, the exposed cables in the mold groove 5001 are squeezed toward the lower front side by the downwardly tilted folding fan baffle 117; the dragging and straightening effect of the wire-smoothing plate 111 is improved, and at the same time, the exposed cables are squeezed downward to prevent the cables from protruding upward again.

[0051] On the basis of the above technical effects, the present invention also has the following advantages:

[0052] The frictional force between the wire drawing plate 111 and the triangular plug cable 555 is increased by the friction block 113 , thereby improving the dragging and straightening effect of the wire drawing plate 111 on the cable in the mold groove 5001 .

[0053] Example 2

[0054] On the basis of Example 1, Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, it also includes a partition 107, a telescopic airbag 201, a fixed block 202 and a ventilation pipe 203; each pressure plate 105 is fixedly connected to the upper middle side of the partition 107; a second cavity 3002 is formed between the pressure plate 105 and the base 3 through the partition 107; two ventilation grooves 10502 are opened in the middle of the pressure plate 105; the first cavity 3001 is connected to the second cavity 3002 through the ventilation grooves 10502; three fixed blocks 202 are fixedly connected to the lower side of each base 3; a telescopic airbag 201 is commonly fixedly connected between all the fixed blocks 202 located on the lower side of the same base 3 and the bracket 1; each fixed block 202 is fixedly connected to a ventilation pipe 203; the telescopic airbag 201 is connected to the first cavity 3001 through the ventilation pipe 203.

[0055] A supercharger is disposed in each fixing block 202 , and each supercharger is communicated with a corresponding ventilation pipe 203 .

[0056] The working principle of the above embodiment is as follows:

[0057] After the three antennae of the triangular plug cable 555 are lifted up by the pressure plate 105 as described in Example 1, the triangular plug cable 555 is still located in the mold groove 5001. Therefore, during the demolding process of the triangular plug cable 555, although the triangular plug cable 555 is in a loose state, the worker still needs to pull up the triangular plug cable 555 vertically to safely demold the triangular plug cable 555. If it is tilted, the triangular plug cable 555 will still be squeezed toward the mold groove 5001, causing the triangular plug cable 555 in a soft state just after injection molding to be squeezed and deformed.

[0058] like Figure 4 In the initial state shown, the pressure plate 105 is pushed upward by the first spring 106. At this time, the pressure plate 105 is blocked by the partition plate 107 and forms a second cavity 3002 between the lower mold 5. Therefore, the second cavity 3002 and the first cavity 3001 are connected to the outside through the mold groove 5001; Figure 3 As shown, in the process of the base 3 sliding left and right by the sliding assembly, the telescopic airbag 201 can communicate with the outside through the second cavity 3002, the first cavity 3001 and the mold groove 5001, and then shrink and stretch along with the base 3. Figure 1 and Figure 7As shown: when the triangular plug cable 555 on the lower mold 5 on the right side is injection-molded, the two bases 3 are driven to move to the right by the sliding assembly. At this time, the telescopic airbag 201 on the left side is stretched and pulled. At this time, after the triangular plug cable 555 is placed on the mold groove 5001, there is a gap between the three tentacles of the triangular plug cable 555 and the mold groove 5001. Therefore, when the telescopic airbag 201 stretches to inhale, the airflow can only enter the second cavity 3002 through the gap between the three tentacles of the triangular plug cable 555 and the mold groove 5001, and then enter the ventilation pipe 203 through the first cavity 3001, and finally enter The triangular plug cable 555 is inserted into the telescopic airbag 201. During this process, the telescopic airbag 201 is stretched and air is sucked, which generates a downward adsorption force on the triangular plug cable 555, so as to prevent the front cable of the triangular plug cable 555 from rubbing against the bracket 1 during the left and right movement of the base 3, causing the triangular plug cable 555 plug to shake and deviate, and detach from the mold groove 5001 to affect the subsequent mold closing and injection molding effect; and when the triangular plug cable 555 on the lower mold 5 on the left is injected, the base 3 is controlled to move to the left by the sliding component. During this process, the upper mold 4 releases the squeeze on the pressure plate 105; the first spring 106 is stretched and reset The pressure plate 105 is squeezed upward, and then the three tentacles of the triangular plug cable 555 are squeezed upward, so that the triangular plug cable 555 is in a loose state, which is convenient for workers to pull out the triangular plug cable 555; at the same time, during this process, the base 3 will squeeze the telescopic airbag 201 in the extended and inflated state on the left side; the gas in the telescopic airbag 201 is squeezed out, and the squeezed gas can only be discharged through the gap between the three tentacles of the triangular plug cable 555 and the mold groove 5001, and the triangular plug cable 555 is still in the mold groove 5001 at this time, so the gas is discharged from the three tentacles of the triangular plug cable 555 and the mold groove 5001. When the gap between 001 is discharged, a strong impact force will be generated on the triangular plug cable 555, which can not only cool the triangular plug cable 555 but also punch the triangular plug cable 555 located in the mold groove 5001 upward, and then punch the triangular plug cable 555 out of the mold groove 5001, and then the worker can easily take out the triangular plug cable 555, and there is no need to pull the triangular plug cable 555 out from a vertical angle, which greatly improves the demoulding efficiency; in summary: the present invention produces multiple functional effects on cable injection molding, improves the effect of cable injection molding, reduces the workload of workers, and greatly improves production efficiency.

[0059] According to the above working principle, we know that the present invention has the following effects:

[0060] In the process of the sliding component driving the base 3 to move left and right through the telescopic airbag 201, the triangular plug cable 555 that has just been placed on the mold 4 groove to be injected is adsorbed to the lower side of the mold groove 5001, so as to prevent the plug of the loose triangular plug cable 555 from shaking and detaching from the mold groove 5001 during the process of the triangular plug cable 555 moving left and right with the base 3, thereby affecting the subsequent mold closing and injection molding effect; the triangular plug cable 555 that has been injected is blown, which can not only cool the triangular plug cable 555, but also flush the triangular plug cable 555 located in the mold groove 5001 upward, and then flush the triangular plug cable 555 out of the mold groove 5001, and then the worker can easily take out the triangular plug cable 555, and there is no need to pull up the triangular plug cable 555 from a vertical angle to take it out, thereby greatly improving the demolding efficiency.

[0061] On the basis of the above technical effects, the present invention also has the following advantages:

[0062] A booster is provided in each of the fixed blocks 202 , and each booster is connected to the corresponding ventilation pipe 203 ; thereby increasing the air pressure when the telescopic airbag 201 is inhaling and blowing, thereby enhancing the adsorption and impact effect of the airflow on the triangular plug cable 555 .

[0063] The above embodiments are only preferred embodiments of the present invention and are not intended to limit the scope of implementation of the present invention. Therefore, all equivalent changes made to the contents described in the claims of the present invention should be included in the scope of the claims of the present invention.
