Description

Technical Field

[0001] The invention belongs to the technical field of molds and relates to a slider mechanism of a multi-color rotary mold. Background Art

[0002] Due to the gradual improvement of product appearance requirements, more and more plastic products require multi-color injection molding. In the multi-color injection molding process, a special multi-color rotational injection mold is required, such as a two-color rotational injection mold. Figure 1 and Figure 2 As shown, the mold includes an upper mold 9 and a lower mold 10, which are combined to form a cavity 101. A slider 3 is provided between the upper mold 9 and the lower mold 10. By injection molding on one side of the cavity, the mold is opened after the injection is completed, and the upper mold 9 or the lower mold 10 is rotated. After the mold is closed again, injection molding is performed on the other side of the cavity.

[0003] However, in traditional multi-color rotary injection molds, after the first mold opening, the existing mold will eject the first molded plastic part through the cooperation of the inclined ejector rod and the slider, resulting in the first molded plastic part being unable to achieve stable positioning and placement when the mold is closed for the second time, affecting the injection molding of the multi-color mold.

[0004] In response to the above problems, people have developed various slider mechanisms for multi-color rotary molds:

[0005] For example, the Chinese patent application [Authorization Announcement No. CN205674437U] discloses a core-pulling mechanism for a two-color mold for producing automotive lighting. The two-color mold includes a fixed mold and a movable mold, which are arranged opposite to each other and can form two cavities. One side of the fixed mold is provided with an inclined guide column, and the movable mold is provided with a core-pulling slider. A through hole is provided in the core-pulling slider and the inclined guide column can be inserted into the through hole. A spring facing the through hole is provided in the core-pulling slider, and a spring is provided between the spring block and the core-pulling slider to move the spring block toward the through hole. The side of the spring block has an inclined surface abutting against the side of the inclined guide column. The fixed mold is also provided with a locking block that can reset and lock the core-pulling slider.

[0006] Although the above structure is provided with a spring rebound block to prevent the inclined guide post from sliding out of the through hole when the mold is opened, since the inclined guide post is only provided in the sliding hole, after the inclined guide post slides into the through hole by thrust, it is also easy to slide out of the through hole by thrust. In order to prevent the inclined guide post from sliding out of the through hole, the elastic force of the spring can be increased to make the inclined guide post difficult to slide out, but it will also make it difficult for the inclined guide post to push the slider to slide into the through hole, thereby making it difficult for the inclined guide post of the core pulling mechanism to quickly fit into the through hole, and the inclined guide post cannot stably drive the slider to move. Summary of the Invention

[0007] The purpose of the present invention is to address the above-mentioned problems in the existing technology and propose a slider mechanism for a multi-color rotary mold. The technical problem to be solved by the present invention is: how to solve the problem that the inclined guide column in the existing multi-color rotary mold cannot quickly drive the slider to move.

[0008] The purpose of the present invention can be achieved through the following technical solutions:

[0009] The cam is secured to the upper edge of the sliding panel and has a lockhole that is formed on the side of the camshaft and is secured to the upper edge of the sliding panel when the cam is engaged.

[0010] Working principle: Before the second cavity of the multi-color rotary mold is injected, the inclined guide pin can be inserted into the strip through hole, and with the second mold closing, the inclined guide pin moves toward one end of the strip through hole. At this time, the side wall of the inclined guide pin can push the limiting part to move toward the outside of the strip through hole and make way, so that the inclined guide pin can pass through the limiting part. The inclined guide pin continues to move to the end of the limiting part close to the hinge point to fit the side wall of the inclined guide pin with the hole wall at one end of the strip through hole. After the second injection is completed, the multi-color rotary mold is opened. At this time, the inclined guide pin can only move vertically under the pressure of the limiting part, thereby driving the slider to move horizontally. Since the end of the slider is convex to form an ejection block, the molded two-color plastic part can be ejected when sliding horizontally, thereby facilitating the demolding of the mold after molding.

[0011] When the guide rod is moved to the position where the side wall of the guide rod is in contact with the hole wall of one end of the bar through hole, the limit part can be reset under the elastic force of the limit spring, and the guide rod can be pressed against the hole wall at one end of the bar through hole, thereby achieving stable limiting of the guide rod, preventing the guide rod from moving in the opposite direction and pushing the limit part to move in the direction outside the bar through hole, thereby making the guide rod able to move quickly until it is pressed on the hole wall of the bar through hole, and the guide rod can stably drive the slider to move under the limiting action of the limit part, thereby improving the convenience and stability of the slider mechanism.

[0012] In the above-mentioned slider mechanism of the multi-color rotary mold, the end surface of the limiting portion away from the hinge point has a guide surface inclined downward, and the inclination direction of the guide surface is the same as the inclination direction of the inclined guide column.

[0013] By providing a guide surface, when the inclined guide column pushes the limiting part open, the guide surface can increase the force-bearing area of ​​the inclined guide column and the limiting part, so that the inclined guide column can push the limiting part open more quickly, further improving the convenience of using the slider mechanism.

[0014] In the slider mechanism of the above-mentioned multi-color rotary mold, the limiting part is located in the middle of the strip through hole, one end of the limiting spring is against the cavity wall of the installation cavity, and the other end is against the limiting part, and the limiting spring is arranged along the width direction of the strip through hole.

[0015] Due to the direction setting of the limit spring, the limit spring can more conveniently push the limit part into the strip through hole, making the reset of the limit part more convenient, and can also push the inclined guide column into place. Under the elastic force of the limit spring, it is not easy to slide out from one end of the strip through hole, thereby improving the stability of the slider mechanism.

[0016] In the above-mentioned slider mechanism of the multi-color rotary mold, the side wall of the inclined guide column away from the hinge point has a planar limiting surface, the end face of the limiting part close to the hinge point is in contact with the limiting surface and the inclined guide column can slide vertically along the limiting surface.

[0017] By providing a planar limiting surface, when the side wall of the inclined guide column fits with the side wall of one side of the strip-shaped through hole, the end face of the limiting portion can also fit with the limiting surface, thereby realizing radial limitation of the inclined guide column, so that the inclined guide column can only slide vertically along the limiting surface, avoiding the inclined guide column from escaping from the limiting portion, and then realizing stable driving of the slider to move, thereby improving the stability of the slider mechanism.

[0018] In the slider mechanism of the above-mentioned multi-color rotating mold, the force block has a swing arm, and the swing arm is connected to the above-mentioned limiting part. When the end face of the limiting part close to the hinge point is in contact with the limiting surface, there is a clearance space between the inclined guide column and the swing arm.

[0019] By setting up the clearance space, when the inclined guide pillar is limited, only the side walls on both sides of the inclined guide pillar are limited along the length direction of the strip through hole. During the molding process, the inclined guide pillar moves up and down with the mold. Therefore, while ensuring that the inclined guide pillar is stably located in the slider mechanism, it also reduces the contact between the inclined guide pillar and the slider mechanism, making it easier for the inclined guide pillar to move up and down, thereby ensuring the stability of the slider mechanism while improving the convenience of using the slider mechanism.

[0020] In the slider mechanism of the above-mentioned multi-color rotary mold, the end protrusion of the limiting part forms a limiting protrusion, and a limiting groove is opened on the inclined guide column. When the inclined guide column is in contact with the hole wall at one end of the strip through hole, the limiting protrusion is embedded in the limiting groove, and the limiting protrusion can slide relatively in the limiting groove.

[0021] The setting of the limiting protrusion does not affect the contraction of the limiting part. After the inclined guide column moves into place, the limiting protrusion can be embedded in the limiting groove after the limiting part rebounds. When the inclined guide column slides up and down, the limiting groove on the inclined guide column can slide along the limiting protrusion, thereby further preventing the inclined guide column from moving out from between the limiting part and the hole wall at one end of the strip through hole, thereby improving the stability of the slider driven by the inclined guide column, and the limiting protrusion can also play a certain guiding role, making the movement path of the inclined guide column more stable.

[0022] In the slider mechanism of the above-mentioned multi-color rotary mold, the limiting part is provided with an elastic block that can move back and forth along the width direction of the strip through hole, and the limiting part is provided with a clearance groove toward the direction of the strip through hole. The inclined guide column can push the elastic block into the clearance groove, and when the inclined guide column is in contact with the hole wall at one end of the strip through hole, the elastic block is reset and abuts against the inclined guide column.

[0023] The setting of the elastic block can enable the elastic block to be quickly pushed away under the action of the inclined guide column when the inclined guide column pushes the limiting part to give way, so that the inclined guide column can be more quickly inserted between the limiting part and the side wall of one end of the strip through hole, thereby enabling the slider mechanism to quickly position the inclined guide column.

[0024] In the above-mentioned slider mechanism of the multi-color rotary mold, a return spring is provided in the said give way groove, and one end of the said return spring is connected to the elastic block.

[0025] The setting of the return spring makes the connection between the elastic block and the slider more convenient, and can also achieve rapid contraction of the elastic block, further improving the convenience of using the slider mechanism.

[0026] In the slider mechanism of the above-mentioned multi-color rotary mold, a hinge block is clamped in the installation cavity, and the end of the force-bearing block has a plate-shaped hinge plate. A sliding groove is provided on the hinge block, and the hinge plate is embedded in the sliding groove and hinged by a hinge shaft. The hinge plate can swing along the sliding groove and the end face of the hinge plate is in contact with the groove wall.

[0027] By clamping the hinge block in the installation cavity, the installation of the force-bearing block is made more convenient, and only a groove needs to be made on the hinge block. The hinge block is small and can be taken out for processing, and the lateral limitation of the hinge plate is achieved by fitting the end face of the hinge plate with the groove wall, so that the force-bearing block swings in the lateral direction and the limiting part is quickly moved out of the strip through hole, thereby improving the stability of the swing of the force-bearing block.

[0028] In the above-mentioned slider mechanism of the multi-color rotary mold, a cover plate that closes the top of the installation cavity is threadedly connected to the slider, and the cover plate can limit the hinge block in the installation cavity.

[0029] The provision of the cover plate makes the installation of the hinge block more convenient, further improving the convenience of assembling the slider mechanism.

[0030] Compared with the existing technology, the slider mechanism of this multi-color rotary mold has the following advantages:

[0031] 1. The limiting part is the end of the force block away from the hinge point. Therefore, it is farther away from the hinge point and the lever arm is longer. Therefore, the inclined guide column can push the limiting part more effortlessly and easily. When the inclined guide column moves to the point where the side wall of the inclined guide column fits into the hole wall at one end of the strip through hole, the limiting part can be reset under the elastic force of the limiting spring and can press the inclined guide column against the hole wall at one end of the strip through hole, thereby achieving stable limiting of the inclined guide column, preventing the inclined guide column from moving in the opposite direction and pushing the limiting part toward the outside of the strip through hole, thereby improving the convenience and stability of the slider mechanism.

[0032] 2. The setting of the limiting protrusion does not affect the contraction of the limiting part. After the inclined guide column moves into place, the limiting protrusion can be embedded in the limiting groove after the limiting part rebounds. When the inclined guide column slides up and down, the limiting groove on the inclined guide column can slide along the limiting protrusion, thereby further preventing the inclined guide column from moving out from between the limiting part and the hole wall at one end of the strip through hole, thereby improving the stability of the inclined guide column driving the slider to move.

[0033] 3. The setting of the elastic block can enable the elastic block to be quickly pushed away under the action of the inclined guide column when the inclined guide column pushes the limit part to give way, so that the inclined guide column can be more quickly inserted between the limit part and the side wall of one end of the strip through hole, thereby enabling the slider mechanism to quickly position the inclined guide column.

DETAILED DESCRIPTION

[0045] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solutions of the present invention, but the present invention is not limited to these embodiments.

[0046] like Figure 1-10As shown, the slider mechanism of the multi-color rotary mold includes an inclined guide column 1, an upper mold 9 and a lower mold 10. The upper mold 9 and the lower mold 10 are combined to form a cavity 101. The slider mechanism is arranged between the upper mold 9 and the lower mold 10. The slider mechanism includes a slide 2 and a slider 3 with an ejection block 34. The slider 3 is slidably set on the slide 2. A limit strip 21 is horizontally set on the slide 2 to limit the slider 3. A strip-shaped through hole 31 is opened in the slider 3 for the inclined guide column 1 to pass through. The hole walls on both sides of the strip through hole 31 are recessed outward to form an installation cavity 32.

[0047] Specifically, if Figure 1-10 As shown, a force-bearing block 4 is hinged in the installation cavity 32, and the ends of the two force-bearing blocks 4 away from the hinge point have a limiting portion 41 that moves along the width direction of the strip through hole 31. A limiting spring 5 with a tendency to always push the limiting portion 41 into the strip through hole 31 is provided in the installation cavity 32. When the inclined guide column 1 moves toward one end of the strip through hole 31, it can push the limiting portion 41 to move toward the outside of the strip through hole 31 and make way. The end of the limiting portion 41 close to the hinge point can be pressed on the inclined guide column 1 and make the side wall of the inclined guide column 1 fit with the hole wall at one end of the strip through hole 31.

[0048] Working principle: After the upper mold 9 and the lower mold 10 are closed for the first time, a cavity 101 is formed, and the molten injection molding material is injected into one side of the cavity 101. At this time, there is no inclined guide column 1 on one side of the cavity 101, so the slider 3 is stably set between the upper mold 9 and the lower mold 10, and the ejector block 34 of the slider 3 will not eject the molded plastic part in the cavity 101; after the upper mold 9 and the lower mold 10 are opened, the upper mold 9 or the lower mold 10 is rotated 180 degrees, and the upper mold 9 and the lower mold 10 are closed, and the molten injection molding material is injected into the other side of the cavity 101. The mold is provided with an inclined guide column 1 on the other side of the cavity 101. During the closing process, the inclined guide column 1 can be inserted into the bar The inclined guide post 1 is in the through hole 31, and with the secondary mold closing, the inclined guide post 1 moves toward one end of the strip through hole 31. At this time, the side wall of the inclined guide post 1 can push the limiting part 41 to move toward the outside of the strip through hole 31 and give way, so that the inclined guide post 1 can pass through the limiting part 41. The inclined guide post 1 continues to move until the side wall of the inclined guide post 1 is in contact with the hole wall at one end of the strip through hole 31. After the second injection molding is completed, the multi-color rotary mold is opened. At this time, the inclined guide post 1 can only move vertically under the pressure of the limiting part 41, thereby driving the slider 3 to move horizontally. Since the end bulge of the slider 3 is formed with an ejection block 34, the molded two-color plastic part can be ejected when sliding horizontally, thereby facilitating the demolding of the mold after molding.

[0049] Since the force block 4 is hinged in the installation cavity 32, when the inclined guide column 1 pushes the limiting portion 41 to move outward of the strip-shaped through hole 31, the limiting portion 41 swings along the hinge point of the force block 4. At this time, the limiting portion 41 is the end of the force block 4 away from the hinge point. Therefore, it is farther away from the hinge point and the force arm is longer. Therefore, the inclined guide column 1 can push the limiting portion 41 more effortlessly and easily, and the limiting portion 41 gives way to it. When the inclined guide column 1 moves to the point where the side wall of the inclined guide column 1 is aligned with the hole wall at one end of the strip-shaped through hole 31, the limiting portion 41 is rotated along the hinge point of the force block 4. When fitted, the limiting portion 41 can be reset under the elastic force of the limiting spring 5, and can press the inclined guide column 1 on the hole wall at one end of the strip through hole 31, thereby achieving stable limiting of the inclined guide column 1, preventing the inclined guide column 1 from moving in the opposite direction and pushing the limiting portion 41 to move toward the outside of the strip through hole 31, so that the inclined guide column 1 can move quickly to press on the hole wall of the strip through hole 31, and the inclined guide column 1 can stably drive the slider 3 to move under the limiting action of the limiting portion 41, thereby improving the convenience and stability of the slider mechanism.

[0050] like Figure 3 As shown, the end face of the limiting portion 41 away from the hinge point has a guide surface 41a inclined downward, and the inclination direction of the guide surface 41a is the same as the inclination direction of the inclined guide column 1, and the side wall of the inclined guide column 1 away from the hinge point has a planar limiting surface 11, the end face of the limiting portion 41 close to the hinge point is fitted with the limiting surface 11 and the inclined guide column 1 can slide vertically along the limiting surface 11, and the hole wall at one end of the strip through hole 31 is a fitting surface 31a fitted with the arc-shaped side wall of the inclined guide column 1.

[0051] like Figure 5-8 As shown, the limiting portion 41 is located in the middle of the strip-shaped through hole 31 , one end of the limiting spring 5 abuts against the cavity wall of the installation cavity 32 , and the other end abuts against the limiting portion 41 , and the limiting spring 5 is arranged along the width direction of the strip-shaped through hole 31 .

[0052] like Figure 4-6 As shown, the force block 4 has a swing arm 42, which is connected to the above-mentioned limiting part 41. When the end face of the limiting part 41 close to the hinge point is in contact with the limiting surface 11, there is a clearance space 6 between the inclined guide column 1 and the swing arm 42.

[0053] like Figure 7 As shown, the end protrusion of the limiting portion 41 forms a limiting protrusion 41b, and a limiting groove 12 is opened on the inclined guide column 1. When the inclined guide column 1 is in contact with the hole wall at one end of the strip-shaped through hole 31, the limiting protrusion 41b is embedded in the limiting groove 12, and the limiting protrusion 41b can slide relatively in the limiting groove 12.

[0054] like Figure 8As shown, the limiting portion 41 has an elastic block 41c that can move back and forth along the width direction of the strip through hole 31, and the limiting portion 41 is provided with a makeshift groove 41d toward the direction of the strip through hole 31. The inclined guide column 1 can push the elastic block 41c to be located in the makeshift groove 41d. When the inclined guide column 1 is in contact with the hole wall at one end of the strip through hole 31, the elastic block 41c is reset and abuts against the inclined guide column 1. A reset spring 7 is provided in the makeshift groove 41d, and one end of the reset spring 7 is connected to the elastic block 41c.

[0055] like Figure 6-9 As shown, a hinge block 8 is clamped in the installation cavity 32, and the end of the force-bearing block 4 has a plate-shaped hinge plate 43. A slide groove 81 is provided on the hinge block 8, and the hinge plate 43 is embedded in the slide groove 81 and hinged by a hinge shaft 82. The hinge plate 43 can swing along the slide groove 81 and the end face of the hinge plate 43 fits with the groove wall. A cover plate 33 that closes the top of the installation cavity 32 is threadedly connected to the slider 3, and the cover plate 33 can limit the hinge block 8 in the installation cavity 32.

[0056] The specific embodiments described herein are merely illustrative of the spirit of the present invention. Persons skilled in the art may make various modifications, additions, or substitutions to the described specific embodiments without departing from the spirit of the present invention or exceeding the scope of the appended claims.
