Description

Technical Field

[0001] This utility model patent relates to the technical field of sprue molds, and more specifically, to multi-cavity switching sprue molds. Background Technology

[0002] Plastic injection molds are the most commonly used molding molds in the production of thermoplastic parts. The corresponding processing equipment for plastic injection molds is a plastic injection molding machine. The plastic is first heated and melted in the heating barrel at the bottom of the injection machine. Then, driven by the screw or plunger of the injection machine, it enters the mold cavity through the injection nozzle and the gating system of the mold. The plastic cools and hardens to form the product, which is then demolded.

[0003] Currently, in order to improve production efficiency, molds are usually designed with multiple cavities, and the switching between cavities is achieved through a sprue insert. For example, the prior patent with authorization announcement number CN216182390U discloses a sprue insert structure for injection molds, including a mold core, a vertically arranged through hole at the upper end of the mold core, and a screw-shaped sprue insert at the upper end of the through hole. The upper end of the sprue insert has an upper horizontal runner arranged in a cross shape, and the upper horizontal runner is connected to a vertical runner, which is arranged vertically and penetrates the sprue insert. The lower end of the vertical runner has a T-shaped lower horizontal runner, which is connected to the mold core runner, and the mold core runner is located on the lower end face of the mold core.

[0004] In the existing technology, when the sprue insert structure switches cavities, the number of cavities switched is small, resulting in fewer sprue paths and thus limited improvement in production efficiency, leading to insufficient production efficiency. Utility Model Content

[0023] Reference Figure 1-3 The image shown is a preferred embodiment of the present invention.

[0024] A multi-cavity switching sprue mold includes a mold core body 1 and a sprue module. The sprue module and the mold core body 1 are assembled together. The mold core body 1 has processing areas A, B, C, and D. The sprue module is arranged longitudinally. The mold core body 1 has a cross channel 12 and a longitudinal channel 11. The cross channel 12 and the longitudinal channel 11 are arranged in a cross shape and are connected. The longitudinal channel 11 is used to transport the processing liquid to processing areas A and D. The cross channel 12 is used to transport the processing liquid to processing areas B and C. The sprue module is respectively arranged corresponding to the cross channel 12 or the longitudinal channel 11. The sprue module is rotated relative to the mold core body 1 under driving force. The sprue module is used to control the cross channel 12 or the longitudinal channel 11 to be in a conducting state or a blocking state.

[0025] The aforementioned multi-cavity switching gate mold, during injection molding, applies rotational force to the gate module to control the conduction or blocking state of the transverse runner 12 and the longitudinal runner 11, thereby controlling the flow direction of the processing liquid material. This allows the processing liquid material to enter processing zones A, B, C, and D respectively, enabling the same mold core to produce different products. In this way, multiple products can be produced without disassembling the mold core body 1, simplifying the injection molding process, greatly improving production efficiency, and reducing production costs.

[0026] The A processing area includes two A processing positions and an A distribution channel. The middle part of the A distribution channel is arranged in a cross shape with the longitudinal channel 11 and is connected to it. The two ends of the A distribution channel are respectively connected to the two A processing positions. In this way, the processing liquid material is transported to the two A processing positions through the A distribution channel to complete the processing of A-type products.

[0027] The sprue module includes a sprue column 2, which is installed on the mold core body 1. The sprue column 2 has a first A side opening and a second A side opening. The first A side opening and the second A side opening are respectively connected to or blocked from the longitudinal flow channel 11, and the first A side opening and the second A side opening convey the processing liquid in opposite directions. The sprue column 2 is rotated relative to the mold core body 1 under the driving force. The rotation of the sprue column 2 is used to control whether the first A side opening and the second A side opening are connected to or blocked from the longitudinal flow channel 11.

[0028] In this way, by applying rotational force to the A-type nozzle column 2, the first A-side port and the second A-side port of the A-type nozzle column 2 are switched between a conducting state and a blocking state, thereby controlling the delivery of the processing liquid.

[0029] The first A-side port and the second A-side port are arranged facing each other. The A-water inlet column 2 is used to synchronously control the first A-side port and the second A-side port to be in a conducting state or a blocking state with the longitudinal flow channel 11. In this way, by synchronously controlling the first A-side port and the second A-side port, the processing liquid material can be synchronously delivered to the two A-processing positions.

[0030] Alternatively, the first A-side port and the second A-side port are arranged in a staggered manner, and the A-side port column is used to independently control whether the first A-side port and the second A-side port are in a connected or blocked state with the longitudinal flow channel 11; in this way, the A-side port column 2 is used to independently control whether the first A-side port or the second A-side port is in a connected or blocked state with the longitudinal flow channel 11; thus, independent control of the first A-side port and the second A-side port is achieved, and the processing liquid is delivered to the two A-processing positions respectively to meet different processing requirements.

[0031] A-type sprue column 2 includes A-type column head and A-type column rod. A-type column head and A-type column rod are arranged in a butt joint and integrally formed. A-type column rod is movably embedded in mold core body 1. A-type column head forms a first A-type side opening or a second A-type side opening. The cross-section of A-type column head and A-type column rod are arranged in a circular shape, and the center of A-type column head and the center of A-type column rod are arranged coaxially.

[0032] This facilitates the driving of sprue column 2 (A) and allows sprue column 2 to rotate relative to mold core body 1, thereby facilitating the control of the rotation angle and ensuring the switching between the conducting and blocking states.

[0033] The multi-cavity switching sprue mold includes a rotating rod 6, which extends longitudinally. The inner end of the rotating rod 6 is fixedly fitted with the A-pillar rod. The rotating rod 6 is movably embedded in the mold core body 1, and the outer end of the rotating rod 6 extends to the outside of the mold core body 1. The outer end of the rotating rod 6 is used to assemble with the driving component, which is used to drive the rotating rod 6 to rotate.

[0034] This allows for the automated application of rotational force, facilitating the driving of the A-pillar and improving driving precision.

[0035] The B processing area includes two B processing positions and a B distribution channel. The middle part of the B distribution channel is arranged in a cross shape with the cross channel 12 and is connected to it. The two ends of the B distribution channel are respectively connected to the two B processing positions. In this way, the processing liquid material is transported to the two B processing positions through the B distribution channel to complete the processing of B type products.

[0036] The cross channel 12 and the longitudinal channel 11 intersect in a cross shape to form a confluence area. The sprue module includes a B sprue column 3, which is located between the B branch channel and the confluence area. The B sprue column 3 has two B side openings. The B sprue column 3 is rotated relative to the mold core body 1 under the driving force. The rotation of the B sprue column 3 is used to control the two B side openings to be in a conducting or blocking state with the cross channel 12.

[0037] In this way, by synchronously controlling the two B-side ports, the processing liquid material can be synchronously delivered to the two B-processing positions.

[0038] The B-type sprue column 3 includes a B-type sprue head and a B-type sprue rod. The B-type sprue head and the B-type sprue rod are arranged in a butt joint and integrally formed. The B-type sprue rod is movably embedded in the mold core body 1. The B-type sprue head forms a first B-type side opening or a second B-type side opening. The cross-sections of the B-type sprue head and the B-type sprue rod are arranged in a circular shape, and the center of the B-type sprue head and the center of the B-type sprue rod are arranged coaxially.

[0039] This facilitates the driving of the B-gate column 3 and also allows the B-gate column 3 to rotate relative to the mold core body 1, thereby making it easier to control the rotation angle and ensure the switching between the conducting and blocking states.

[0040] The multi-cavity switching sprue mold includes a rotating rod 6, which extends longitudinally. The inner end of the rotating rod 6 is fixedly fitted with the B-pillar rod. The rotating rod 6 is movably embedded in the mold core body 1, and the outer end of the rotating rod 6 extends to the outside of the mold core body 1. The outer end of the rotating rod 6 is used to be assembled with the driving component, which is used to drive the rotating rod 6 to rotate.

[0041] This allows for the automated application of rotational force, facilitating the driving of the B-pillar and improving driving precision.

[0042] The C processing area includes two C processing positions and a C distribution channel. The middle of the C distribution channel is arranged in a cross shape with the cross channel 12 and is connected to it. The two ends of the C distribution channel are respectively connected to the two C processing positions. In this way, the processing liquid material is transported to the two C processing positions through the C distribution channel to complete the processing of C-type products.

[0043] The cross channel 12 and the longitudinal channel 11 are arranged in a cross shape to form a confluence area. The sprue module includes a C sprue column 4, which is located between the C branch channel and the confluence area. The C sprue column 4 has two C side openings. The C sprue column 4 is rotated relative to the mold core body 1 under the driving force. The rotation of the C sprue column 4 is used to control the two C side openings to be in a conducting or blocking state with the cross channel 12.

[0044] In this way, by synchronously controlling the two C-side ports, the processing liquid material can be synchronously delivered to the two C-processing positions.

[0045] The C-type sprue column 4 includes a C-type head and a C-type rod. The C-type head and the C-type rod are connected and integrally formed. The C-type rod is movably embedded in the mold core body 1. The C-type head forms a first C-type side opening or a second C-type side opening. The cross-sections of the C-type head and the C-type rod are arranged in a circular shape, and the center of the C-type head and the center of the C-type rod are arranged coaxially.

[0046] This facilitates the driving of the C-gate column 4 and also allows the C-gate column 4 to rotate relative to the mold core body 1, thereby making it easier to control the rotation angle and ensure the switching between the conducting and blocking states.

[0047] The multi-cavity switching sprue mold includes a rotating rod 6, which extends longitudinally. The inner end of the rotating rod 6 is fixedly fitted with the C-pillar rod. The rotating rod 6 is movably embedded in the mold core body 1, and the outer end of the rotating rod 6 extends to the outside of the mold core body 1. The outer end of the rotating rod 6 is used to be assembled with a driving component, which drives the rotating rod 6 to rotate.

[0048] This allows for the automated application of rotational force, facilitating the driving of the C-pillar and improving driving precision.

[0049] The D processing area includes four D processing positions, a D horizontal flow channel, and two D vertical flow channels. The middle part of the D horizontal flow channel is connected to the end of the vertical flow channel 11 to form a flow distribution area. The two ends of the D horizontal flow channel are connected to the middle parts of the two D vertical flow channels respectively. The two D vertical flow channels are connected to the two D processing positions respectively.

[0050] In this way, the processing liquid is transported to the D transverse diversion channel through the longitudinal diversion channel 11, and then transported to the two D longitudinal diversion channels through the D transverse diversion channel. The processing liquid is then transported to the D processing position through the D longitudinal diversion channel to complete the processing of D type products.

[0051] The sprue module includes a D-sprue column 5, which is located in the flow divider area. The D-sprue column 5 has two D-side openings and a D-inlet. The D-sprue column 5 is rotated relative to the mold core body 1 under the driving force. The rotation of the D-sprue column 5 is used to control the two D-side openings to be in a state of conduction or blockage with the D-lateral flow divider channel, and the rotation of the D-sprue column 5 is used to control the D-inlet to be in a state of conduction or blockage with the longitudinal flow channel 11.

[0052] In this way, under the action of D inlet, the longitudinal flow channel 11 conveys the processing liquid to the D transverse flow channel. By synchronously controlling the two D side ports, the processing liquid is synchronously conveyed to the two D longitudinal flow channels, thereby realizing the synchronous conveying of processing liquid to the four D processing positions.

[0053] The D-type sprue column 5 includes a D-type sprue head and a D-type sprue rod. The D-type sprue head and the D-type sprue rod are connected and integrally formed. The D-type sprue rod is movably embedded in the mold core body 1. The D-type sprue head forms two D-type side openings and a D-type inlet. The cross-sections of the D-type sprue head and the D-type sprue rod are arranged in a circular shape, and the center of the D-type sprue head and the center of the D-type sprue rod are arranged coaxially.

[0054] This facilitates the driving of the D-gate column 5 and also allows the D-gate column 5 to rotate relative to the mold core body 1, thereby making it easier to control the rotation angle and ensure the switching between the conducting and blocking states.

[0055] The multi-cavity switching sprue mold includes a rotating rod 6, which extends longitudinally. The inner end of the rotating rod 6 is fixedly fitted with the D-pillar rod.
