Description

[Technical field]

[0001] The present invention relates to the technical field of molding devices, and in particular to a hanging chain integral molding device and a molding method. [Background technology]

[0002] Chains can be seen everywhere in daily life, such as Figure 1 As shown, the hanging chain 100' usually includes a hanging ring 1' for hanging and a short chain 2' connected to the hanging ring 1', and the short chain 2' includes a plurality of chain links 21' connected in series; at the same time, a hanging piece 3', such as a decorative plate, can be connected to the end of the short chain 2' away from the hanging ring 1', and a hanging ring 31' connected to the short chain 2' is formed on the hanging piece 3'.

[0003] For the hanging ring 1' and the chain ring 21', in order to facilitate the connection of the hanging ring 1' and each chain ring 21', a disconnected gap needs to be formed on the hanging ring 1' and the chain ring 21'. When assembling the hanging chain 100', an external force needs to be applied to open the gap of the hanging ring 1' or the chain ring 21' to form an assembly opening. After the hanging ring 1' or the chain ring 21' that needs to be connected in series is assembled through the assembly opening, an external force is applied to restore the assembly opening to a gap. This leads to the following defects in actual use: 1. The hanging ring 1' and the chain ring 21' need to be produced one by one and then assembled, which has low production efficiency and high production cost; 2. There are gaps on the hanging ring 1' and the chain ring 21', which are easy to fall off due to pulling during use. In view of the above-mentioned problems, the inventor of this case conducted an in-depth study on the problem, and thus this case was created. [Summary of the invention]

[0056] Embodiment 1

[0057] See also Figures 1 to 13 As shown, the present invention is an integrated molding device 100 for a hanging chain, the molding device 100 comprises an upper mold 1, a lower mold 2, a left mold 3 and a right mold 4. When the present invention is implemented, the upper mold 1, the lower mold 2, the left mold 3 and the right mold 4 all need to be connected to a driving mechanism (not shown) to drive the upper mold 1, the lower mold 2, the left mold 3 and the right mold 4 to open and close the mold by the driving mechanism;

[0058] The top of the lower mold 2 is concave downward to form a first slide groove 21, and the first slide groove 21 extends to the left and right ends of the top of the lower mold 2; the bottom of the upper mold 1 is concave upward at a position corresponding to the first slide groove 21 to form a second slide groove 11, and the second slide groove 11 extends to the left and right ends of the bottom of the upper mold 1; the left mold 3 is slidably arranged on the left side of the first slide groove 21 and the second slide groove 11, so that the left mold 3 can slide along the first slide groove 21 and the second slide groove 11 to open and close the mold; the right mold 4 is slidably arranged on the right side of the first slide groove 21 and the second slide groove 11, so that the right mold 4 can slide along the first slide groove 21 and the second slide groove 11 to open and close the mold;

[0059] Please refer to Figure 10-13As shown, the left mold 3 is formed with a first upper inclined surface 31 and a first lower inclined surface 32 which are gradually inclined from left to right toward the middle at one end facing the right mold 4, and the right mold 4 is formed with a second upper inclined surface 41 and a second lower inclined surface 42 which are gradually inclined from right to left toward the middle at one end facing the left mold 3; a first punch 22 is protruded upwardly between the left mold 3 and the right mold 4 in the first slide groove 21, a first left inclined surface 221 which is fitted with the first lower inclined surface 32 after mold closing is formed on the left side of the first punch 22, and a first right inclined surface 222 which is fitted with the second lower inclined surface 42 after mold closing is formed on the right side of the first punch 22; a second punch 12 is protruded downwardly between the left mold 3 and the right mold 4 in the second slide groove 11, a second left inclined surface 121 which is fitted with the first upper inclined surface 31 after mold closing is formed on the left side of the second punch 12, and a second right inclined surface 122 which is fitted with the second upper inclined surface 41 after mold closing is formed on the right side of the second punch 12;

[0060] At least one first semi-annular cavity is provided between the first lower inclined surface 32 and the first left inclined surface 221, and a second semi-annular cavity is provided between the second upper inclined surface 41 and the second right inclined surface 122, which is connected to the first semi-annular cavity and forms a first chain ring cavity, so as to use the first chain ring cavity to form a complete chain ring; at least one third semi-annular cavity is provided between the second lower inclined surface 42 and the first right inclined surface 222, and one end of the third semi-annular cavity is located between the two ends of the first semi-annular cavity, and a fourth semi-annular cavity is provided between the first upper inclined surface 31 and the second left inclined surface 121, which is connected to the third semi-annular cavity and forms a second chain ring cavity. A semi-annular cavity is used to form a complete chain ring by utilizing the second chain ring cavity. At the same time, because one end of the third semi-annular cavity is located between the two ends of a first semi-annular cavity, after the molding is completed, the chain ring formed by the first chain ring cavity can be directly connected in series with the chain ring formed by the first chain ring cavity, and no additional assembly operation is required subsequently. A flow channel connected to the first chain ring cavity and the second chain ring cavity is formed on the upper mold 1 and the lower mold 2, so that the liquid required for molding (such as zinc alloy liquid) can be input into the first chain ring cavity and the second chain ring cavity by utilizing the flow channel, so that a plurality of chain rings connected in series can be directly molded.

[0061] The technical solution of the present invention is further described below by a specific example: taking the need to form 5 chain links as an example, two first semi-annular cavities can be provided at intervals between the first lower inclined surface 32 and the first left inclined surface 221, and two second semi-annular cavities can be provided correspondingly between the second upper inclined surface 41 and the second right inclined surface 122, and each second semi-annular cavity forms a complete first chain link cavity with a first semi-annular cavity; similarly, three third semi-annular cavities can be provided at intervals between the second lower inclined surface 42 and the first right inclined surface 222, and one end of the third semi-annular cavity located in the middle position is located at one of the first semi-annular cavities. Between the two ends of the cavity, the other end of the third semi-annular cavity located in the middle position is located between the two ends of the other first semi-annular cavity, one end of the third semi-annular cavity located at one end is located between the two ends of one of the first semi-annular cavities, and one end of the third semi-annular cavity located at the other end is located between the two ends of the other first semi-annular cavity. At the same time, three fourth semi-annular cavities are correspondingly arranged between the first upper inclined surface 31 and the second left inclined surface 121, and each fourth semi-annular cavity forms a complete second chain ring cavity with a third semi-annular cavity, so that after the molding is completed, 5 chain rings directly connected in series can be obtained.

[0062] In some embodiments of the present invention, a hanging ring cavity is formed between the top surface of the lower mold 2, the bottom surface of the upper mold 1, the side wall of the left mold 3 and the side wall of the right mold 4 at the front side of the first chute 21 and the second chute 11, and the hanging ring cavity is connected with the flow channel, so that the liquid required for molding is transported to the hanging ring cavity by the flow channel, and the hanging ring is directly molded in the hanging ring cavity;

[0063] One end of the first chain link cavity or the second chain link cavity is located within the inner circle of the hanging ring cavity, so that the formed hanging ring can be directly connected to a chain link in series, and no additional assembly operation is required later. The top surface of the lower mold 2 and the bottom surface of the upper mold 1 are provided with a first blocking protrusion 51 inside the inner circle of the hanging ring cavity for assisting in forming the first chain link cavity or the second chain link cavity and preventing the hanging ring cavity from communicating with the first chain link cavity or the second chain link cavity, so as to ensure that the hanging ring cavity and the first chain link cavity or the second chain link cavity do not mutually communicate during molding. Influence, the top surface of the lower mold 2 is formed with a first avoidance recess 52 at a position corresponding to the first barrier protrusion 51 of the upper mold 1, and the bottom surface of the upper mold 1 is formed with a first barrier protrusion 51 of the lower mold 2. For example, when the present invention is implemented, the first barrier protrusion 51 can be formed on the left side of the top surface of the lower mold 2, and the first avoidance recess 52 can be formed on the right side of the top surface of the lower mold 2. Correspondingly, the first avoidance recess 52 needs to be formed on the left side of the bottom surface of the upper mold 1, and the first barrier protrusion 51 needs to be formed on the right side of the bottom surface of the upper mold 1.

[0064] In some embodiments of the present invention, a hanging piece cavity is formed between the top surface of the lower mold 2 and the bottom surface of the upper mold 1 at the rear side of the first chute 21 and the second chute 11, and a hanging ring cavity connected to the hanging piece cavity is formed between the top surface of the lower mold 2, the bottom surface of the upper mold 1, the left mold 3 and the right mold 4. The hanging piece cavity is connected to the flow channel, so that the liquid required for molding is transported to the hanging piece cavity and the hanging ring cavity by the flow channel, so as to mold a hanging piece with a hanging ring;

[0065] One end of the first chain ring cavity or the second chain ring cavity is located within the inner circle of the hanging ring cavity, so that the formed hanging ring can be directly connected in series with a chain ring, and no additional assembly operation is required later; the top surface of the lower mold 2 and the bottom surface of the upper mold 1 are provided with a second blocking protrusion 61 within the inner circle of the hanging ring cavity for assisting in forming the first chain ring cavity or the second chain ring cavity and preventing the hanging ring cavity from communicating with the first chain ring cavity or the second chain ring cavity, so as to ensure that the hanging ring cavity and the first chain ring cavity or the second chain ring cavity will not be connected during molding. Due to mutual influence, the top surface of the lower mold 2 is formed with a second avoidance recess 62 at a position corresponding to the second barrier protrusion 61 of the upper mold 1, and the bottom surface of the upper mold 1 is formed with a second barrier protrusion 61 of the lower mold 2. For example, when the present invention is implemented, a second barrier protrusion 61 can be formed on the left side of the top surface of the lower mold 2, and a second avoidance recess 62 can be formed on the right side of the top surface of the lower mold 2. Correspondingly, a second avoidance recess 62 needs to be formed on the left side of the bottom surface of the upper mold 1, and a second barrier protrusion 61 needs to be formed on the right side of the bottom surface of the upper mold 1.

[0066] By adopting the above technical solution of the present invention, at least the following beneficial effects are achieved:

[0067] 1. Through the above-mentioned molding device 100 of the present invention, a chain with multiple chain links, a chain with multiple chain links and a hanging ring connected to one end of the chain, or the entire hanging chain component 100' including the chain, the hanging ring and the hanging piece can be well integrated into one piece, and no additional assembly operation is required later, thereby effectively improving production efficiency and reducing production costs.

[0068] 2. The chain rings, hanging rings or hanging rings of the hanging parts can be integrally formed and directly connected together. No disconnected gaps are required on the chain rings, hanging rings or hanging rings of the hanging parts, so that the connection between the chain rings, hanging rings or hanging rings is very reliable, ensuring that they will not fall off due to pulling during use, thereby improving the safety of use.

[0069] As a preferred embodiment of the present invention, the angles between the first upper slope 31, the first lower slope 32, the second upper slope 41 and the second lower slope 42 and the horizontal line are all 45°, and the angles between the first left slope 221, the first right slope 222, the second left slope 121 and the second right slope 122 and the vertical line are all 45°.

[0070] In some embodiments of the present invention, in order to better form the chain ring, please focus on Figure 10-13 As shown, the first semi-annular cavity includes a first semi-annular groove 321 formed on the first lower inclined surface 32 and a second semi-annular groove 2211 formed on the first left inclined surface 221; the second semi-annular cavity includes a third semi-annular groove 411 formed on the second upper inclined surface 41 and a fourth semi-annular groove 1221 formed on the second right inclined surface 122;

[0071] In order to better form the chain ring, the third semi-annular cavity includes a fifth semi-annular groove 421 formed on the second lower inclined surface 42 and a sixth semi-annular groove 2221 formed on the first right inclined surface 222; the fourth semi-annular cavity includes a seventh semi-annular groove 311 formed on the first upper inclined surface 31 and an eighth semi-annular groove 1211 formed on the second left inclined surface 121.

Since it is necessary to directly connect the hanging ring formed by the hanging ring cavity with the chain ring formed by the first chain ring cavity or the second chain ring cavity, it is necessary to use the third auxiliary groove 511 of the first blocking protrusion 51 located inside the hanging ring cavity to form a part of the first chain ring cavity or the second chain ring cavity. Similarly, it is necessary to form a part of the hanging ring cavity on the side wall of the left mold 3 and the side wall of the right mold 4, so that the formed hanging ring can be directly connected with the chain ring, and it is ensured that the hanging ring cavity and the first chain ring cavity or the second chain ring cavity will not affect each other during the molding process.

It should be noted that in the embodiment of the present invention, the fourth auxiliary groove 34 is formed on the side wall of the left mold 3, and the step surface 44 flush with the top surface of the lower mold 2 is formed on the right mold 4, but the present invention is not limited to this. In specific implementation, the fourth auxiliary groove can also be formed on the side wall of the right mold 4, and the step surface flush with the top surface of the lower mold 2 can be formed on the left mold 3. In addition, since one side of the hanging ring is usually a plane, the fifth main groove 15 is only formed on the bottom surface of the upper mold 1 in the embodiment of the present invention, but the present invention is not limited to this. In specific implementation, the required main groove can also be set on the top surface of the lower mold 2 according to actual needs.

[0075] A fifth auxiliary groove 611 for assisting in forming the first chain ring cavity or the second chain ring cavity is formed on the second blocking protrusion 61. Since the hanging ring formed by the hanging ring cavity needs to be directly connected in series with the chain ring formed by the first chain ring cavity or the second chain ring cavity, it is necessary to utilize the fifth auxiliary groove 611 of the second blocking protrusion 61 located inside the hanging ring cavity to form a part of the first chain ring cavity or the second chain ring cavity. Similarly, it is necessary to form a part of the hanging ring cavity on the left mold 3 and the right mold 4. In this way, the formed hanging ring and the chain ring can be directly connected in series, and it is ensured that the hanging ring cavity and the first chain ring cavity or the second chain ring cavity will not affect each other during the molding process.

[0076] In some embodiments of the present invention, in order to reliably deliver the liquid required for molding to each cavity for molding, the flow channel includes a main input flow channel 71 located on any one side of the first chain link cavity and the second chain link cavity and a main output flow channel 72 located on the other side of the first chain link cavity and the second chain link cavity; the first chain link cavity, the second chain link cavity, the hanging ring cavity and the hanger cavity are all connected to the main input flow channel 71 through an input branch channel 73, and the first chain link cavity, the second chain link cavity, the hanging ring cavity and the hanger cavity are all connected to the main output flow channel 72 through an output branch channel 74. In a specific implementation of the present invention, the main input channel 71 and the main output channel 72 are evenly divided into an upper part and a lower part at the positions corresponding to the first slide groove 21 and the second slide groove 11. For example, a lower main input channel is formed on the bottom wall on the right side of the first slide groove 21, and an upper main input channel is formed on the top wall on the right side of the second slide groove 11, and each first chain link cavity is connected to the upper main input channel, and each second chain link cavity is connected to the lower main input channel; similarly, a lower main output channel is formed on the bottom wall on the left side of the first slide groove 21, and an upper main output channel is formed on the top wall on the left side of the second slide groove 11, and each first chain link cavity is connected to the lower main output channel, and each second chain link cavity is connected to the upper main output channel.

[0077] As a specific embodiment of the present invention, the top of the lower mold 2 is provided with positioning protrusions 25 at the four corners, and the bottom of the upper mold 1 is provided with positioning grooves 16 that cooperate with the positioning protrusions 25 to achieve positioning, so that the positioning protrusions 25 and the positioning grooves 16 can be used to cooperate to achieve positioning of the lower mold 2 and the upper mold 1, ensuring that the lower mold 2 and the upper mold 1 can be accurately and reliably molded.

[0078] As a specific embodiment of the present invention, the top of the lower mold 2 is provided with positioning grooves at the four corners, and the bottom of the upper mold 1 is provided with a positioning convex portion that cooperates with the positioning grooves to achieve positioning, so that the positioning convex portion and the positioning groove cooperate to achieve positioning of the lower mold 2 and the upper mold 1, ensuring that the lower mold 2 and the upper mold 1 can be accurately and reliably molded.

[0079] In the specific implementation of the present invention, the left mold 3 is provided with a first limit plate 35 at one end away from the right mold 4, and the right mold 4 is provided with a second limit plate 45 at one end away from the left mold 3. Through the design of the first limit plate 35 and the second limit plate 45, on the one hand, the first limit plate 35 can be used to limit the sliding of the left mold 3 to ensure that the left mold 3 can be accurately molded, and similarly, the second limit plate 45 can limit the sliding of the right mold 4 to ensure that the right mold 4 can be accurately molded; on the other hand, the first limit plate 35 and the second limit plate 45 can be conveniently used to connect the driving mechanism.

[0080] In some embodiments of the present invention, Figure 2-Figure 5 As shown, a movable seat 26 is further provided below the lower mold 2, and a plurality of demoulding ejector pins 8 are arranged on the movable seat 26. A pin movable hole 27 connected to the flow channel is provided on the lower mold 2 at a position corresponding to each of the demoulding ejector pins 8, and the upper end of each of the demoulding ejector pins 8 is inserted into one of the pin movable holes 27. In the specific implementation of the present invention, demoulding ejector pins 8 can be provided at positions corresponding to the main input flow channel 71, the main output flow channel 72, the input branch flow channel 73 and the output branch flow channel 74 on the movable seat 26. After molding, the residual liquid on each flow channel will also solidify and form waste 101' connected to the hanging chain 100'. After demolding, it is only necessary to cut off the waste. Therefore, by setting the demolding ejector 8 at the positions corresponding to the main input flow channel 71, the main output flow channel 72, the input branch flow channel 73 and the output branch flow channel 74, not only can the molded hanging chain 100' and the waste 101' be pushed upward to realize demolding, but also the demolding ejector 8 will not act on the hanging chain 100', which can avoid damage to the hanging chain 100'. At the same time, it is necessary to connect the driving mechanism of the lower mold 2 with the movable seat 26, so that the driving mechanism can drive the movable seat 26 and the demolding ejector 8 to move up and down together, so as to realize the demolding of the molded hanging chain 100'; and the driving mechanism of the upper mold 1 can be directly connected to the top of the upper mold 1, so as to use the driving mechanism to drive the upper mold 1 to move up and down.

[0081] Guide pillars 9 are provided at the four corners of the movable seat 26, and guide pillar holes 28 are opened on the lower mold 2 at the positions corresponding to each of the guide pillars 9. The upper end of each of the guide pillars 9 is inserted into one of the guide pillar holes 28, so that the guide pillars 9 and the guide pillar holes 28 cooperate to limit and guide the up and down movement of the demoulding ejector pin 8, ensuring that the demoulding ejector pin 8 can reliably eject the formed hanging chain component 100' from the top of the lower mold 2.

Please refer to the detailed introduction of the first embodiment for details, which will not be repeated here.

[0084] The molding method comprises the following steps:

[0085] Step S1, controlling the upper mold 1, the lower mold 2, the left mold 3 and the right mold 4 to close the mold, so as to form various cavities required for forming the hanging chain component 100', such as the first chain link cavity, the second chain link cavity, the hanging ring cavity or the hanging component cavity;

[0086] Step S2, injecting liquid required for molding into each mold cavity required for molding the hanging chain member 100' through the flow channel, so that the liquid solidifies in each mold cavity to form the hanging chain member 100'; in the specific implementation of the present invention, the liquid required for molding can be zinc alloy liquid, but the present invention is not limited to this, and other metal liquids can also be used in the specific implementation;

[0087] Step S3, after the chain part 100' is formed, the upper mold 1 is controlled to rise to open the mold, and at the same time, the left mold 3 is controlled to move to the left and the right mold 4 is controlled to move to the right to open the mold, and then the formed chain part 100' is lifted up as a whole to complete the demolding operation; when the present invention is implemented, the demolding ejector 8 arranged under the flow channel can be used to lift the formed chain part 100 upward, so that the chain part 100' is separated from the top of the lower mold 2, thereby completing the demolding operation. After the demolding is completed, the waste material 101' only needs to be cut off to obtain the required waste material 101'.
