Description

Technical Field

[0001] This invention relates to the field of mold processing technology, and more specifically to a slanted-ejector type secondary ejection mechanism for the injection gate. Background Technology

[0002] After automotive plastic trim parts are injection molded, the gate (sprue) remaining on the trim parts is removed by a gate cutter inside the injection mold when the mold opens. For example, the automotive plastic trim part injection mold with an in-mold gate cutting mechanism disclosed in Chinese Patent Publication No. CN209682807U requires a gate cutter inside the injection mold to remove the gate (sprue) remaining on the trim parts after injection molding. This requires adding a gate cutter to the injection mold, resulting in a complex injection mold structure. Moreover, the gate (sprue) cut off by the gate cutter cannot automatically detach from the injection mold, requiring manual removal of the gate (sprue) from the injection mold, which is cumbersome. Currently, the injection molds used in automotive air vents (objects) have the same shortcomings as the injection molds mentioned above. In addition, since the injection mold for the car air vent (object) is large, there is a large height difference between different parts of the car air vent (e.g., the middle is high and the two ends are low). If a sliding block submerged gate is used, the cost of steel for the sliding block structure will increase when the product height difference is large. Summary of the Invention

[0003] To address the shortcomings and defects of existing technologies, a tilting-top submerged secondary ejection mechanism for the glue outlet is provided, which has fewer subsequent manual operation steps, lower costs, and a more compact structure.

[0004] The inclined-top submerged type secondary ejection mechanism includes: A mold body, wherein the mold body is provided with a core; An inclined top is provided on a core, and the inclined top and the core are provided with a cavity for forming an object. The inclined top is provided with a submarine gate, which is connected to the cavity, and the slurry enters the cavity through the submarine gate. A floating pin is disposed on the inclined top at the lower part of the submerged gate; The ejection mechanism includes a top column movable in a first direction and a top rod movable in a second direction, wherein the first direction is inclined toward the second direction. In the mold-closed state, the central axis of the floating pin is offset from the central axis of the ejector pin; In the demolded state, the ejector pin drives the angled ejector to move along the first direction to detach from the core. The angled ejector moves along the first direction until the lower end of the floating pin is opposite to the upper end of the ejector pin. The push rod moves along the second direction until it comes into contact with the floating needle, and continues to move to push out the material in the submerged gate.

[0005] With the above structure, the inclined ejector submerged gate secondary ejection mechanism of the present invention has the following advantages compared with the prior art: When it is necessary to form an object, the mold is closed first. In the mold closed state, the cavity of the inclined ejector and the core are combined, the floating pin is located below the submerged gate, and the lower end of the floating pin is staggered from the upper end of the ejector rod. At this time, the slurry is injected into the submerged gate, and the slurry enters the cavity through the submerged gate to form the required object. When it is necessary to demold the molded object, the ejector pin moves along the first direction, which drives the inclined ejector to move synchronously. The object is separated from the cavity on the core. At this time, the inclined ejector can move to the point where the lower end of the floating pin is opposite to the upper end of the ejector rod, and the central axis of the floating pin coincides with the central axis of the ejector rod. Furthermore, the ejector pin moving in the second direction can drive the floating pin upward, thereby ejecting the colloid from the submarine gate. This allows the connection between the colloid and the workpiece to be severed during demolding. Subsequent manual trimming of the glue gate on the object and cleaning of the glue inside the sprue in the inclined top are not required, reducing subsequent processes and improving the production efficiency and yield of the object. There is no need to set up a gate cutting mechanism in the mold, which results in lower cost and a more compact structure.

[0006] In addition, compared with the existing sliding block type nozzle, less steel is used, which further reduces costs.

[0007] As an improvement of the present invention, the ejection mechanism further includes a first ejector plate and a second ejector plate disposed above the first ejector plate, wherein the first ejector plate is connected to the lower end of the ejector column and the second ejector plate is connected to the lower end of the ejector rod. A disengagement mechanism is also provided between the first ejector plate and the second ejector plate. The second ejector plate moves upward, and the first ejector plate moves synchronously through the disengagement mechanism. The first ejector plate drives the ejector column to move in the first direction, and the second ejector plate drives the ejector rod to move in the second direction. The lower end of the floating pin is opposite to the upper end of the push rod. The disengagement mechanism disconnects the connection between the first push pin plate and the second push pin plate. The second push pin plate continues to move upward until the push rod drives the floating pin to move upward and push out the material in the submerged gate.

[0008] As an improvement of the present invention, the dislocation mechanism includes a locking pin and a bracket. The locking pin is disposed on a first ejector plate, and the bracket is connected to a second ejector plate. The bracket is provided with a locking groove. An elastic member is abutted between the first ejector plate and the locking pin. The elastic member drives the head of the locking pin to extend laterally into the locking groove, so that when the second ejector plate moves upward, the bracket supports the locking pin, thereby linking the first ejector plate to move. The disengagement mechanism also includes a transmission pin, which drives the locking pin to move backward so that the head of the locking pin moves out of the locking slot, and the second ejector plate continues to move upward but cannot drive the first ejector plate.

[0009] As an improvement of the present invention, the head of the locking pin is provided with an inclined transmission surface, the transmission pin is placed at the front end of the locking pin and the bottom end of the transmission pin is fixed on the base plate, the transmission pin is provided with a driving surface that cooperates with the transmission surface, the locking pin moves upward with the second ejector plate until the transmission surface contacts the driving surface, and as the locking pin continues to move upward, the driving surface drives the locking pin to move backward so that the head of the locking pin disengages from the locking groove.

[0010] As an improvement of the present invention, the first ejector plate and the second ejector plate are stacked together, the bracket is fixed to the side wall of the second ejector plate and the lower end extends downward to the outside of the side wall of the first ejector plate, the inner side of the bracket is formed with a slot for the transmission pin to pass through, and the slot is provided at the lower part of the bracket and located on both sides of the transmission. The second ejector plate has an assembly groove on its side wall. The locking pin is disposed in the assembly groove, with its head extending out of the assembly groove. The elastic element abuts against the bottom of the assembly groove and the tail of the locking pin.

[0011] As an improvement of the present invention, a limiting post is provided on the first ejector plate, the limiting post extends upward and passes through the second ejector plate, the disengagement mechanism disengages the connection between the first ejector plate and the second ejector plate, and the upper end of the limiting post abuts against the mold body.

[0012] As an improvement of the present invention, the angle between the top rod and the horizontal line c is 90°, and the angle between the top rod and the horizontal line c is 89°.

[0013] As an improvement of the present invention, the core is provided with an assembly space for accommodating the inclined top.

[0014] As an improvement of the present invention, the ejection mechanism further includes a driving member, which is connected to the second ejector plate and drives the second ejector plate to move upward.

[0015] As an improvement of the present invention, a spring is provided between the floating needle and the inclined top, and the pre-tension of the spring drives the floating needle to always have a tendency to move downward and reset. Attached Figure Description

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0028] Please see Figure 1-10 As shown, the inclined jack 3 submerged type secondary ejection mechanism includes: Mold body 1, wherein the mold body 1 is provided with a core 2; An inclined top 3 is provided on the core 2. The inclined top 3 and the core 2 are provided with a cavity 4 for forming the object 14. The inclined top 3 is provided with a submarine gate 3.1, which is connected to the cavity 4. The slurry enters the cavity 4 through the submarine gate 3.1. Floating pin 5, which is disposed on the inclined top 3 at the lower part of the submerged gate 3.1; The ejection mechanism includes a top column 6 movable in a first direction and a top rod 7 movable in a second direction, wherein the first direction is inclined toward the second direction. In the mold-closed state, the central axis of the floating pin 5 is offset from the central axis of the ejector pin 7; In the demolded state, the ejector pin 6 drives the angled ejector 3 to move along the first direction to detach from the core 2. The angled ejector 3 moves along the first direction until the lower end of the floating pin 5 is opposite to the upper end of the ejector pin 7. The push rod 7 moves along the second direction until it abuts against the floating needle 5, and continues to move to push out the material in the submerged gate 3.1.

[0029] With the above structure, the submerged gate secondary ejection mechanism of the inclined ejector 3 of the present invention has the following advantages compared with the prior art: When it is necessary to form an object 14, the mold is closed first. In the mold closed state, the inclined ejector 3 and the cavity 4 of the core 2 are combined, the floating pin 5 is located below the submerged gate 3.1, and the lower end of the floating pin 5 is offset from the upper end of the ejector rod 7. At this time, the slurry is injected into the submerged gate 3.1. The slurry enters the cavity 4 through the submerged gate 3.1, and the required object 14 can be formed. When it is necessary to demold the molded object 14, the ejector pin 6 moves along the first direction, which drives the inclined ejector 3 to move synchronously. The object 14 is separated from the cavity 4 on the core 2. At this time, the inclined ejector 3 can move to the point where the lower end of the floating pin 5 is opposite to the upper end of the ejector pin 7, and the central axis of the floating pin 5 coincides with the central axis of the ejector pin 7. Furthermore, the push rod 7 moves in the second direction, which can drive the floating pin 5 to move upward, thereby pushing out the colloid inside the submarine gate 3.1 and severing the connection between the colloid and the object 14. This solves the problem of separating the existing inclined top 3 tunnel-type glue outlet from the inclined top 3, eliminating the need for glue outlet trimming and reducing subsequent processes.

[0030] The inclined top 3-submerged gate structure uses less steel than the existing slider submerged gate structure. Of course, the inclined jack 3 in this device can also be a straight jack.

[0031] As an improvement of the present invention, the ejection mechanism further includes a first ejector plate 8 and a second ejector plate 9 disposed above the first ejector plate 8. The first ejector plate 8 is connected to the lower end of the ejector column 6, the upper end of the ejector column 6 passes through the second ejector plate 9 and is connected to the inclined ejector 3, and the second ejector plate 9 is connected to the lower end of the ejector rod 7. A disengagement mechanism is also provided between the first ejector plate 8 and the second ejector plate 9. The second ejector plate 9 moves upward, and the first ejector plate 8 moves synchronously through the disengagement mechanism. The first ejector plate 8 drives the ejector column 6 to move along the first direction, and the second ejector plate 9 drives the ejector rod 7 to move along the second direction. The lower end of the floating pin 5 is opposite to the upper end of the push rod 7. The disengagement mechanism disconnects the connection between the first push pin plate 8 and the second push pin plate 9. The second push pin plate 9 continues to move upward until the push rod 7 drives the floating pin 5 to move upward and push out the material in the submerged gate 3.1.

[0032] After the above improvements, in the mold-closed state, the disengagement mechanism connects the first ejector plate 8 with the second ejector plate 9; During demolding, firstly, the second ejector plate 9 moves upward, driving the ejector rod 7 to move along the second direction. At the same time, the second ejector plate 9 moves upward synchronously through the disengagement mechanism in conjunction with the first ejector plate 8. The above-mentioned movement stroke is 90mm. Then, the first ejector plate 8 can drive the inclined ejector 3 to move along the first direction through the ejector pin 6. During the movement of the inclined ejector 3, the lower end of the floating pin 5 moves laterally outward by 1.6mm. Then, the central axis of the floating pin 5 is coaxial with the central axis of the ejector rod 7, and the lower end of the floating pin 5 abuts against the upper end of the ejector rod 7. Furthermore, the disengagement mechanism disengages the first ejector plate 8 from the second ejector plate 9. At this point, the upward movement of the second ejector plate 9 cannot be linked to the movement of the first ejector plate 8. The first ejector plate 8, through the pusher 6 and the inclined pusher 3, remains in a fixed position. The continued upward movement of the second ejector plate 9 drives the pusher rod 7 to move in the second direction and contact the floating pin 5. This movement stroke is 30mm, and the floating pin 5 moves with the same stroke, causing the material in the submerged gate 3.1 to detach from the inclined pusher 3 and sever the connection with the object 14. During this process, the mold body 1 is also provided with an ejector mechanism for ejecting the object 14. When the ejector mechanism is in a fixed state at the inclined ejector 3 position, it ejects the object 14 upward so that the object 14 is separated from the inclined ejector 3. The above demolding process achieves the separation of object 14 from core 2 and cuts off the connection between the colloid and object 14 in steps. The demolding steps are reasonably designed and the yield rate of object 14 is high.

[0033] As an improvement of the present invention, the disengagement mechanism includes a locking pin 10 and a bracket 11. The locking pin 10 is disposed on the first ejector plate 8, and the bracket 11 is connected to the second ejector plate 9. The bracket 11 is provided with a slot 11.1. An elastic member 10.2 is provided between the first ejector plate 8 and the locking pin 10. The elastic member 10.2 drives the head of the locking pin 10 to extend laterally into the slot 11.1 so that when the second ejector plate 9 moves upward, the bracket 11 supports the locking pin 10, thereby linking the first ejector plate 8 to move. The disengagement mechanism also includes a transmission pin 12, which drives the locking pin 10 to move backward, causing the head of the locking pin 10 to move out of the locking groove 11.1. The second ejector plate 9 continues to move upward but cannot drive the first ejector plate 8. After the above improvements, the mechanical disengagement structure has the characteristics of stable operation, reliability, and long service life.

[0034] As an improvement of the present invention, the head of the locking pin 10 is provided with an inclined transmission surface 10.1, the transmission pin 12 is placed at the front end of the locking pin 10, and the bottom end of the transmission pin 12 is fixed on the base plate 16. The transmission pin 12 is provided with a driving surface 12.1 that cooperates with the transmission surface 10.1. The locking pin 10 moves upward with the second ejector plate 9 until the transmission surface 10.1 contacts the driving surface 12.1. As the locking pin 10 continues to move upward, the driving surface 12.1 drives the locking pin 10 to move backward so that the head of the locking pin 10 disengages from the locking groove 11.1. After the above improvement, the transmission surface 10.1 is inclined with a high tail end and a low front end, while the driving surface 12.1 has the opposite structure. The transmission pin 12 below the driving surface 12.1 has a notch, and the transmission pin 12 is fixed to the base plate 16 and will not move upward or downward. In the mold-closed state, the head of the transmission pin 12 passes through the notch and enters the slot 11.1 on the bracket 11 on both sides of the transmission pin 12; During demolding, the drive unit 15 drives the second ejector plate 9 to move upward. The slot 11.1 of the bracket 11 supports the retaining pin 10, so as to move synchronously with the first ejector plate 8. Since the position of the transmission pin 12 is fixed, when the transmission surface 10.1 contacts the drive surface 12.1, it can drive the retaining pin 10 to move towards the tail end until the head of the retaining pin 10 disengages from the slot 11.1. At this time, the second ejector plate 9 cannot drive the first ejector plate 8 to move synchronously. The above improvement has the characteristics of stable operation, reliability, and long service life.

[0035] In addition, a positioning mechanism (not shown in the attached drawings) is provided on the mold body 1. When the connection between the first ejector plate 8 and the second ejector plate 9 is disengaged (i.e., after the head of the transmission pin 12 moves out of the slot 11.1), the positioning mechanism will position the first ejector plate 8 so that it cannot move down. As the second ejector plate 9 moves downward, the driving surface 12.1 gradually moves upward relative to the transmission surface 10.1, and the transmission pin 10 gradually moves forward until the head of the transmission pin 10 is reset and re-enters the slot 11.1. At this time, the reconnection between the second ejector plate 9 and the first ejector plate 8 is completed, the positioning mechanism releases the positioning of the first ejector plate 8, and the first ejector plate 8 can move downward and reset synchronously with the second ejector plate 9.

[0036] As an improvement of the present invention, the first ejector plate 8 and the second ejector plate 9 are stacked together, the bracket 11 is fixed to the side wall of the second ejector plate 9, and the lower end extends downward to the outside of the side wall of the first ejector plate 8. The bracket 11 has a slot 11.2 formed on the inner side for the transmission pin 12 to pass through, and the slot 11.1 is provided at the lower part of the bracket 11 and located on both sides of the transmission. The second ejector plate 9 has an assembly groove 9.1 on its side wall. The locking pin 10 is disposed in the assembly groove 9.1, with its head protruding from the groove. The elastic element 10.2 abuts against the bottom of the assembly groove 9.1 and the tail of the locking pin 10. After the above improvement, the locking pin 10 is connected to the slot 11.2 on the side wall of the first ejector plate 8, and the bracket 11 is connected to the side wall of the second ejector plate 9. The inner side of the bracket 11 forms an assembly groove 9.1 for the transmission pin 12 to pass through. The disengagement structure has a reasonable layout, high compactness, and reduced space occupation.

[0037] As an improvement of the present invention, a limiting post 8.1 is provided on the first ejector plate 8. The limiting post 8.1 extends upward and passes through the second ejector plate 9. The disengagement mechanism disengages the first ejector plate 8 from the second ejector plate 9. The upper end of the limiting post 8.1 abuts against the mold body 1. After the above improvement, after the first ejector plate 8 and the second ejector plate 9 are disengaged, the upper end of the limiting post 8.1 abuts against the mold body 1, further restricting the upward movement of the first ejector plate 8, avoiding excessive movement of the inclined ejector 3, and thus avoiding interference with the demolding process of the object 14. The device has high operational reliability and improves the yield rate of the molded object 14.

[0038] As an improvement of the present invention, the angle between the top rod 7 and the horizontal line c is 90°, and the angle between the top rod 7 and the horizontal line c is 89°.

[0039] As an improvement of the present invention, the core 2 is provided with an assembly space for accommodating the inclined top 3. After the above improvement, the inclined top 3 is embedded in the core 2, making the structure compact and the layout reasonable.

[0040] As an improvement of the present invention, the ejection mechanism further includes a driving member 15, which is connected to the second ejector plate 9, and the driving member 15 drives the second ejector plate 9 to move upward.

[0041] As an improvement of the present invention, a spring 13 is provided between the floating pin 5 and the inclined ejector 3. The spring 13 is pre-tensioned to drive the floating pin 5 to always have a tendency to move downward and reset. After the above improvement, when the mold is closed, the second ejector plate 9 moves downward and drives the first ejector plate 8 to move synchronously. After the lower end of the floating pin 5 loses contact with the upper end of the ejector rod 7, the spring 13 can automatically reset the floating pin 5 to the lower end of the submarine gate 3.1. The automatic reset structure of the floating pin 5 makes the device reliable in operation and has a long service life.

[0042] Specifically, in this device, there are two inclined ejectors 3, which are respectively set at both ends of the core 2. Floating pins 5 are independently set on the core 2, and ejector rods 7 are independently set on the second ejector plate 9 corresponding to the floating pins 5. The mold cavity on the inclined top 3 is used for forming the outer end of the object 14, and the mold cavity on the core 2 is used for forming the middle part of the object 14. The height of the cavity in the middle of the core 2 is higher than the height of the cavity on the inclined top 3, and there is a height difference between the cavities to form an object 14 with a large height difference; The submerged gate 3.1 on the sloping top 3 adopts a horn-shaped injection structure design.

[0043] The above are merely preferred embodiments of the present invention. The scope of protection of the present invention is not limited to the above embodiments. All technical solutions falling within the scope of the present invention's concept are within the scope of protection of the present invention. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of the present invention should also be considered within the scope of protection of the present invention.
