Description

Technical Field

[0001] The invention relates to the technical field of plastic moulds, in particular to a plastic mould device which is convenient for installation and fixing. Background Art

[0002] Plastic molds are tools used to manufacture plastic products, and they play a vital role in industrial production. These molds are designed to mold molten plastic materials into products of various shapes and sizes through processes such as injection, blow molding, extrusion, and compression molding. In order to improve the efficiency of combined assembly with injection molding equipment and facilitate maintenance and repair, plastic molds are often set in a form that is easy to install, fix, and disassemble.

[0003] Some existing plastic molds are provided with a flow channel for circulating coolant to cool down the injection molded products quickly, and a liquid injection pipe connected to the flow channel for injecting and removing coolant is provided on the surface side wall. However, the connection mechanism between the liquid injection pipe and the conduit led from the circulation pump and the coolant tank lacks a mechanism for blocking and collecting the coolant leaked out when the liquid injection pipe and the conduit are separated and disassembled, resulting in a large amount of direct leakage and waste of coolant, and may also cause large-scale splashing, large-scale pollution of the injection molding equipment or surrounding supporting equipment, and subsequent additional manual large-scale wiping and cleaning of the equipment is required, which is troublesome and inconvenient to operate;

[0004] Although some docking connection mechanisms are equipped with mechanisms for blocking and collecting leaked coolant, most of these mechanisms cannot directly discharge the collected leaked coolant into the coolant tank for recycling, and require additional manual pouring, which is still cumbersome and inconvenient to operate. Summary of the invention

[0005] In view of this, the present invention provides a plastic mold device that is easy to install and fix, so as to solve the problem that most of the blocking and collecting mechanisms cannot directly discharge the leaked coolant collected into the coolant tank for recycling, and require additional manual pouring by humans, which is troublesome and inconvenient to operate.

[0006] The technical solution proposed by the present invention is: a plastic mold device that is easy to install and fix, specifically comprising an upper mold body, a hydraulic drive cylinder and a U-shaped vertical support frame; the top of the upper mold body is symmetrically threaded with two long vertical support frames, and the U-shaped vertical support frame is placed above the top of the upper mold body;

[0007] Two coolant injection pipes are symmetrically threadedly fastened on the longitudinal side of the upper mold body, and a rubber sealing sleeve is extruded on the outer portion of the coolant injection pipe;

[0008] Two sliding positioning frames for transverse sliding are symmetrically installed at the bottom side of the U-shaped vertical support frame. The sliding positioning frame is composed of an L-shaped main support rod and a plug plate welded to the head end of the L-shaped main support rod, and a butt pipe sleeve is welded to the tail end of the L-shaped main support rod. When the two sliding positioning frames slide close to each other, the plug plate and the long longitudinal support frame are inserted and matched, and the butt pipe sleeve and the coolant injection pipe sleeve are inserted and matched; a U-shaped driving frame is installed on the U-shaped vertical support frame for lifting and sliding, and two sets of first connecting rods are symmetrically rotated and connected between the U-shaped driving frame and the two sliding positioning frames;

[0009] A drain pipe is welded on the circumferential outer wall of the butt-joint pipe sleeve.

[0010] Furthermore, a mounting ring with a sealing structure at the tail end is welded on the middle section of the coolant injection pipe, and the cross-section of the rubber sealing sleeve is a T-shaped structure. The tail end part of the rubber sealing sleeve is inserted into and fits with the mounting ring and is in contact with the tail end plug of the mounting ring.

[0011] Furthermore, the U-shaped vertical support frame is threadedly fastened and hoisted at the bottom end of the telescopic rod of the hydraulic drive cylinder, and a U-shaped abutment plate is welded at the bottom of the U-shaped vertical support frame, and a push bolt for rotatingly installing the vertical support is passed through the middle position of the U-shaped abutment plate, and the push bolt is screwed through the middle part of the U-shaped drive frame;

[0012] The U-shaped abutment plate abuts against two long longitudinal bracing frames;

[0013] Two rod sleeves are symmetrically welded at both ends of the U-shaped driving frame, and the two rod sleeves are slidably matched with the vertical support part of the U-shaped vertical support frame, and two horizontal support square rods are symmetrically welded on the bottom side of the vertical support part of the U-shaped vertical support frame.

[0014] Furthermore, a square sleeve is welded to the top of the horizontal part of the L-shaped main support rod, the square sleeve is slidably matched with the cross support square rod, the head end of the first connecting rod is rotatably connected to the rod sleeve, and the tail end is rotatably connected to the square sleeve.

[0015] Furthermore, the drain pipe is supported downward, and is connected to an external coolant tank through a hose, and two butt pipe sleeves are used for liquid inlet and liquid outlet respectively and are connected to an external circulation pump and a coolant tank through hoses respectively;

[0016] A through hole is provided between the discharge pipe and the butt-joint pipe sleeve. When the butt-joint pipe sleeve and the mounting collar are inserted and fitted into place, the rubber sealing sleeve squeezes and seals the through hole. When the two butt-joint pipe sleeves slide away from each other, the through hole and the rubber sealing sleeve are separated and opened.

[0017] Furthermore, two F-shaped mounting parts are symmetrically welded and hoisted at the bottom of the cross bracing part of the U-shaped driving frame, and a stop shaft is slidably installed on each of the two F-shaped mounting parts through spring pushing;

[0018] The two blocking shafts are arranged vertically. When the two butt-jointed pipe sleeves slide away from each other and the through-port is separated and opened from the rubber sealing sleeve, the two blocking shafts are inserted downward and protrude from the bottom of the U-shaped stop plate.

[0019] Furthermore, two limiting rings are welded and sleeved on the bottom of the push bolt at intervals, and the two limiting rings are rotatably fitted with the upper and lower ends of the U-shaped abutment plate respectively.

[0020] Furthermore, a reminder shaft is slidably installed at the inner center of the push bolt through the spring push, the top end of the reminder shaft protrudes from the push bolt, and a horizontally arranged cross is welded to the protruding part of the bottom end;

[0021] Four horizontally arranged track square rods are welded around the lower side limit ring, and a driving member is slidably installed on the track square rod. The driving member is composed of an outer semicircular guide plate and an inner square sliding sleeve welded together. Four second connecting rods are connected around the four driving members and the cross.

[0022] Furthermore, as the push bolt rotates, the semicircular guide plates of the four driving parts successively come into contact with the two downwardly inserted and protruding blocking shafts to drive the reminder shaft to slide back and forth up and down to poke the palm to implement the reminder.

[0023] The plastic mold device provided by the present invention, which is easy to install and fix, has the following beneficial effects:

[0024] When the present invention is in use, the up-and-down sliding U-shaped driving frame can push and drive the two sliding positioning frames and the two plug plates and two docking pipe sleeves thereon to slide synchronously left and right toward each other, completing the insertion and withdrawal, loosening and tightening of the two long longitudinal support frames and the two coolant injection pipes at one time, and disassembly and assembly of the upper mold body, eliminating the trouble of inserting and withdrawal, loosening and tightening the coolant docking pipe and the plug-in positioning components step by step when disassembling and assembling the upper mold body. The operation is convenient and easy to use, which helps to improve the efficiency of disassembly and assembly of the upper mold body and the U-shaped vertical support frame.

[0025] In addition, when the two butt-joint tube sleeves slide outward and are disassembled from the two coolant injection pipes, their circumferential inner walls continue to rub and squeeze against the two rubber sealing sleeves. At this time, a sealed interception space is formed between the interior thereof and the two coolant injection pipes. The coolant leaking from the two butt-joint tube sleeves and the two coolant injection pipes can be surrounded and blocked and collected through the two interception spaces. Compared with the prior art that lacks a blocking and collecting mechanism, it can avoid direct large-scale leakage and waste of coolant, avoid large-scale splashing of coolant, and pollute large areas of the injection molding equipment or surrounding supporting equipment, thereby eliminating the trouble of subsequent additional manual large-scale wiping and cleaning of the equipment, and is relatively convenient to operate and use.

[0026] In addition, the two butt-joint pipe sleeves can directly discharge the leaked coolant collected in their internal sealed spaces into the coolant tank for recycling through the two hoses connected thereto. Compared with the blocking and collecting mechanism in the prior art, the trouble of subsequent manual pouring of the collected leaked coolant into the coolant tank can be eliminated. The operation is convenient and efficient. The opening and closing operations of the through-port and the drain pipe can be directly carried out in the process of sliding, pulling and tightening the butt-joint pipe sleeve and the mounting ring. This eliminates the trouble of additional manual operation of the through-port and the drain pipe each time the upper mold body is disassembled and assembled and the leaked coolant is collected and drained, which helps to indirectly further simplify the disassembly and assembly operation steps of the upper mold body.

[0027] In addition, when the reminder shaft slides back and forth up and down, it can intermittently poke the palm of the hand that is holding the top of the push bolt to twist the push bolt, reminding the operator that the through-port and the rubber sealing sleeve have been separated and opened, so that the operator can stop screwing the driving push bolt in time and stop continuously withdrawing the docking sleeve, avoiding the operator from failing to stop withdrawing the docking sleeve at the appropriate time when the through-port has been opened without effective reminders, and safely withdrawing the docking sleeve and the rubber sealing sleeve, causing the docking sleeve to fail to intercept, collect and drain the leaked coolant, which helps to ensure the normal and effective implementation of the docking sleeve function.

[0048] In order to make the purpose, technical solution and advantages of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the described embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0049] Please refer to Figures 1 to 6 ;

[0050] For convenience of description, the length direction of the long longitudinal support frame 102 is marked as the front-to-back direction, and the width direction is marked as the left-to-right direction; Embodiment 1

[0051] The present invention proposes a plastic mold device that is easy to install and fix, including an upper mold body 1, a coolant injection pipe 101, a long longitudinal support frame 102, a mounting collar 1011, a rubber sealing sleeve 1012, a hydraulic drive cylinder 2, a U-shaped vertical support frame 3, a U-shaped drive frame 301, a rod sleeve 3011, an F-shaped mounting member 3012, a stop shaft 3013, a first connecting rod 302, a horizontal support square rod 303, a U-shaped abutment plate 304, a push bolt 305, a limit ring 3051, a track square rod 3052, a prompt shaft 306, a cross 3061, a drive member 3062, a second connecting rod 3063, a sliding positioning frame 4, a square sleeve 402, a plug plate 401, a butt pipe sleeve 5, and a drain pipe 501; the top of the upper mold body 1 is symmetrically threadedly fastened with two long longitudinal support frames 102, and the U-shaped vertical support frame 3 is placed above the top of the upper mold body 1;

[0052] Among them, two coolant injection pipes 101 are symmetrically threadedly fastened on the longitudinal side of the upper mold body 1 close to the long longitudinal support frame 102, and a rubber sealing sleeve 1012 is extruded on the outer part of the coolant injection pipe 101;

[0053] Two sliding positioning frames 4 for transverse sliding are symmetrically installed at the bottom side of the U-shaped vertical support frame 3. The sliding positioning frame 4 is composed of an L-shaped main support rod and a plug plate 401 welded to the head end of the L-shaped main support rod, and a butt pipe sleeve 5 is welded to the tail end of the L-shaped main support rod. When the two sliding positioning frames 4 slide close to each other, the plug plate 401 and the long longitudinal support frame 102 are inserted and matched, and the butt pipe sleeve 5 and the coolant injection pipe 101 are inserted and matched, and the plug plate 401 and the long longitudinal support frame 102 are inserted and matched. The plug-in fit is used to plug and position the upper mold body 1 and the U-shaped vertical support frame 3 together, and to limit the upper mold body 1 up and down, front and back, and the butt-joint pipe sleeve 5 is plugged and connected with the coolant injection pipe 101, which is used to connect its body, and when the butt-joint pipe sleeve 5 is plugged and connected with the coolant injection pipe 101, its tail end abuts against the tail end of the rubber sealing sleeve 1012 and the mounting ring 1011, and can also limit the upper mold body 1 left and right. This, together with the plug-in plate 401, can be used to implement the maximum position of the upper mold body 1. The upper mold body 1 is stably and firmly connected to the U-shaped vertical support frame 3 by multi-dimensional limiting in up and down, left and right, and front and back; a U-shaped driving frame 301 is installed on the U-shaped vertical support frame 3 for lifting and sliding, and two groups of first connecting rods 302 are symmetrically rotated between the U-shaped driving frame 301 and the two sliding positioning frames 4. The U-shaped driving frame 301, the two groups of first connecting rods 302 and the two sliding positioning frames 4 are connected together to form two crank slider mechanisms. Through these two mechanisms, the U-shaped driving frame can slide up and down. 301 can push and drive the two sliding positioning frames 4 and the two plug plates 401 and two docking pipe sleeves 5 thereon to slide synchronously to the left and right, and complete the insertion and tightening of the two long longitudinal support frames 102 and the two coolant injection pipes 101 at one time, and implement the disassembly and assembly of the upper mold body 1, eliminating the trouble of inserting and tightening the coolant docking pipes and the plug-in positioning components step by step when disassembling and assembling the upper mold body 1. The operation is convenient and easy to use, which helps to improve the disassembly and assembly efficiency of the upper mold body 1 and the U-shaped vertical support frame 3;

[0054] When the two butt-jointed pipe sleeves 5 are inserted and matched with the two coolant injection pipes 101, the circumferential inner walls of the two butt-jointed pipe sleeves 5 are squeezed and contacted with the two rubber sealing sleeves 1012 to implement butt sealing. When the two butt-jointed pipe sleeves 5 slide outward and are disassembled and separated from the two coolant injection pipes 101, the circumferential inner walls thereof continue to rub and squeeze with the two rubber sealing sleeves 1012. At this time, a sealed interception space is formed between the interior thereof and the two coolant injection pipes 101. The coolant leaking from the two butt-jointed pipe sleeves 5 and the two coolant injection pipes 101 can be surrounded and blocked and collected through the two interception spaces. Compared with the prior art lacking a blocking and collecting mechanism, the coolant can be prevented from being directly leaked and wasted in large quantities, and the coolant can be prevented from being splashed in a large area, and the injection molding equipment or surrounding supporting equipment can be contaminated in a large area, thereby eliminating the trouble of subsequent additional manual large-area wiping and cleaning of the equipment, and the operation and use are relatively convenient.

[0055] A drain pipe 501 is welded on the circumferential outer wall of the butt-joint pipe sleeve 5, the drain pipe 501 is supported downward, and the drain pipe 501 is connected to the external coolant tank through a hose, and the two butt-joint pipe sleeves 5 are used for liquid inlet and liquid outlet respectively and are connected to the external circulation pump and the coolant tank through hoses respectively; a through opening is provided between the drain pipe 501 and the butt-joint pipe sleeve 5;

[0056] During the process of the two butt-joint pipe sleeves 5 sliding outward and being disassembled and separated from the two coolant injection pipes 101, as the two butt-joint pipe sleeves 5 are continuously pulled out, the through-openings between the two discharge pipes 501 and the two butt-joint pipe sleeves 5 are separated and opened from the two rubber sealing sleeves 1012. At this time, the two butt-joint pipe sleeves 5 can directly discharge the leaked coolant collected in their internal sealed spaces into the coolant tank for recycling through the two hoses connected thereto. Compared with the blocking and collecting mechanism in the prior art, the trouble of manually pouring the collected leaked coolant into the coolant tank can be eliminated, and the operation is convenient and efficient.

[0057] Preferably, a mounting collar 1011 with a plugging structure at the tail end is welded on the middle section of the coolant injection pipe 101, and the cross section of the rubber sealing sleeve 1012 is a T-shaped structure, and the tail end portion of the rubber sealing sleeve 1012 is inserted and matched with the mounting collar 1011, and is in contact with the tail end plugging plate of the mounting collar 1011;

[0058] Two tightening bolts for fixing the rubber sealing sleeve 1012 are symmetrically penetrated and screwed on the circumferential outer wall of the mounting ring 1011 .

[0059] Preferably, the U-shaped vertical support frame 3 is threadedly fastened and hoisted at the bottom end of the telescopic rod of the hydraulic drive cylinder 2, and a U-shaped abutment plate 304 is welded at the bottom of the U-shaped vertical support frame 3, and a push bolt 305 for rotating and installing a vertical support is passed through the middle position of the U-shaped abutment plate 304, and the push bolt 305 is screwed through and matched with the middle part of the U-shaped driving frame 301, and the push bolt 305 is used for forward and reverse rotation to drive the U-shaped driving frame 301 to slide up and down, and provide a driving force for pulling and tightening the two sliding positioning frames 4 and the two plug plates 401 thereon and the two docking pipe sleeves 5;

[0060] When the U-shaped vertical support frame 3 is positioned and connected with the upper mold body 1, the U-shaped abutment plate 304 abuts against the two long longitudinal support frames 102, so that the U-shaped vertical support frame 3 can bear the upward reverse thrust received when the upper mold body 1 slides downward and docks with the lower mold, avoiding directly relying on the two relatively thin and low-strength plug plates 401 and the long longitudinal support frames 102 to resist the reverse thrust, and preventing the two plug plates 401 and the long longitudinal support frames 102 from being pushed and broken;

[0061] Two rod sleeves 3011 are symmetrically welded at both ends of the U-shaped driving frame 301, and the two rod sleeves 3011 slide with the vertical support part of the U-shaped vertical support frame 3, and two horizontal support square rods 303 are symmetrically welded on the bottom side of the vertical support part of the U-shaped vertical support frame 3.

[0062] Preferably, a square sleeve 402 is welded to the top of the horizontal part of the L-shaped main support rod, and the square sleeve 402 is slidably matched with the horizontal support square rod 303. The head end of the first connecting rod 302 is rotatably connected to the rod sleeve 3011, and the tail end is rotatably connected to the square sleeve 402.

[0063] Preferably, when the butt-joint pipe sleeve 5 and the mounting collar 1011 are inserted and matched in place, the rubber sealing sleeve 1012 squeezes and seals the through-hole. When the two butt-joint pipe sleeves 5 slide away from each other, the through-hole and the rubber sealing sleeve 1012 are separated and opened, and the opening and closing operation of the through-hole and the drain pipe 501 can be directly performed in the process of sliding, pulling and tightening the butt-joint pipe sleeve 5 and the mounting collar 1011. This saves the time of disassembling and assembling the upper mold body 1 each time and collecting and draining the leaked coolant. , the trouble of manually operating the through-port and the drain pipe 501 is eliminated, which helps to indirectly further simplify the disassembly and assembly steps of the upper mold body 1; when the butt-joint pipe sleeve 5 is plugged and connected with the installation collar 1011, the through-port and the drain pipe 501 are closed, which can prevent the pumped coolant with a certain pressure from being directly discharged into the coolant tank through the through-port and the drain pipe 501, affecting the normal large-flow circulation of the coolant and reducing the cooling effect on the upper mold body 1;

[0064] It is worth noting that: when collecting and draining the leaked coolant, it is necessary to ensure that the through-port and the rubber sealing sleeve 1012 are separated and opened, but the docking sleeve 5 should not be completely separated from the rubber sealing sleeve 1012; when disassembling and assembling the upper mold body 1, the upper mold body 1 should be slid down and docked against the lower mold, and the lower mold should be used to support the upper mold body 1.

[0065] Preferably, two F-shaped mounting members 3012 are symmetrically welded and hoisted at the bottom of the cross bracing portion of the U-shaped driving frame 301, and a stop shaft 3013 is slidably installed on both F-shaped mounting members 3012 through spring pushing;

[0066] The two blocking shafts 3013 are arranged vertically. When the two butt-jointed pipe sleeves 5 slide away from each other and the through-port and the rubber sealing sleeve 1012 are separated and opened, the two blocking shafts 3013 are inserted downward and protruded from the bottom of the U-shaped stop plate 304 (refer to Fig.11 ).

[0067] Preferably, two limiting rings 3051 are welded and sleeved on the bottom of the push bolt 305 at intervals, and the two limiting rings 3051 are rotatably fitted with the upper and lower ends of the U-shaped abutment plate 304 respectively.

[0068] On the basis of the first embodiment, the second embodiment, as Figures 7 to 11 As shown:

[0069] The plastic mold device convenient for installation and fixing also includes a prompt shaft 306 which is slidably installed at the center of the pushing bolt 305 through the spring push, the top of the prompt shaft 306 protrudes from the pushing bolt 305, and the protruding part of the bottom end is welded with a horizontally arranged cross 3061;

[0070] Four horizontally arranged track square rods 3052 are welded around the lower side limit ring 3051, and a driving member 3062 is slidably installed on the track square rod 3052. The driving member 3062 is composed of a semicircular guide plate on the outside and a square sleeve on the inside that are welded together. Four second connecting rods 3063 are connected around the four driving members 3062 and the cross 3061. The four second connecting rods 3063 and the four driving members 3062 and the cross 3061 are connected together to form four crank slider mechanisms. Through these four mechanisms, sliding any driving member 3062 inward can drive the cross 3061 to slide up and down.

[0071] Preferably, as the advancing bolt 305 rotates, the semicircular guide plates of the four driving members 3062 are in contact with the two blocking shafts 3013 protruding downward in sequence (refer to Fig.11 ), through the arc guiding principle of the semicircular guide plate and used together with the power transmission of the two blocking shafts 3013 inserted and protruding downward, the advancing bolt 305 drives the U-shaped driving frame 301 to slide downward when rotating, and controls the two docking pipe sleeves 5 to slide outward and disassemble and separate the two coolant injection pipes 101. At the same time, the two driving parts 3062 at two opposite positions can be pushed and driven to slide close to each other, driving and controlling the cross 3061 and the prompt shaft 306 to slide back and forth up and down. When the prompt shaft 306 slides back and forth up and down, it can intermittently poke and hold the top of the advancing bolt 305 to push the advancing bolt 305 against the advancing bolt The palm of the hand that implements the twisting drive of the bolt 305 reminds the operator that the through-port and the rubber sealing sleeve 1012 have been separated and opened, so that the operator can stop screwing the driving push bolt 305 in time and stop the continuous extraction of the butt joint sleeve 5, so as to avoid the operator failing to stop the extraction operation of the butt joint sleeve 5 in time at the appropriate time when the through-port has been opened without effective reminder, and safely extract the butt joint sleeve 5 and the rubber sealing sleeve 1012, so that the interception, collection and drainage function of the butt joint sleeve 5 for the leaked coolant fails, which helps to ensure the normal and effective implementation of the function of the butt joint sleeve 5;

[0072] The reminder shaft 306 indirectly utilizes the rotational driving force of the push bolt 305 to drive the up and down sliding to implement the top-poking reminder, which saves the trouble of additional manual effort to drive the reminder shaft 306 or the need to configure an additional driving motor for the reminder shaft 306. It is easy to operate and use, and helps to reduce the implementation cost of the top-poking reminder function; in addition, the two blocking shafts 3013 serve as components that convert the rotational driving force of the push bolt 305 into a driving force for the up and down sliding of the reminder shaft 306. When the through-port is separated from the rubber sealing sleeve 1012 and opened, it can be automatically pushed down by the U-shaped driving frame 301 to protrude from the bottom of the U-shaped abutment plate 304 and be power-coupled with the four driving parts 3062. This allows the top-poking reminder function of the reminder shaft 306 to be automatically triggered when the through-port is opened, with better timeliness and eliminating the need for manual triggering or The trouble of additionally setting up an automatic control device composed of PLC and various sensors to implement automatic triggering is avoided, and the operation is convenient, which helps to further reduce the implementation cost of the top-stamping reminder function; the two blocking shafts 3013 are installed by spring pushing, and when they slide down and protrude from the bottom of the U-shaped support plate 304, they are not normally inserted into the interval space between the four driving members 3062, and the bottom end is in contact with the semicircular guide plate and cannot be normally and effectively coupled with the power of the driving member 3062. Then, they can be pushed back by the driving member 3062 to compress the spring thereon to slide upward into the empty space. Compared with the two blocking shafts 3013 being directly welded or fixed in other forms, this can avoid the driving member 3062 from being pushed, bent or broken and damaged, which helps to indirectly extend the service life of the overall components implementing the top-stamping reminder function.

[0073] Working principle: The U-shaped driving frame 301, two sets of first connecting rods 302 and two sliding positioning frames 4 are connected together to form two crank slider mechanisms. Through these two mechanisms, the U-shaped driving frame 301 that slides up and down can push and drive the two sliding positioning frames 4 and the two plug plates 401 and two connecting pipe sleeves 5 thereon to slide toward each other left and right synchronously, and complete the insertion and tightening of the two long longitudinal support frames 102 and the two coolant injection pipes 101 at one time, and implement the disassembly and assembly of the upper mold body 1;

[0074] When the two butt-joint pipe sleeves 5 are inserted and matched with the two coolant injection pipes 101, the circumferential inner walls of the two butt-joint pipe sleeves 5 are squeezed and contacted with the two rubber sealing sleeves 1012 to implement butt sealing. When the two butt-joint pipe sleeves 5 slide outward and are disassembled and separated from the two coolant injection pipes 101, the circumferential inner walls thereof continue to rub and squeeze with the two rubber sealing sleeves 1012. At this time, a sealed interception space is formed between the interior thereof and the two coolant injection pipes 101. The coolant leaking from the two butt-joint pipe sleeves 5 and the two coolant injection pipes 101 can be surrounded and blocked and collected through the two interception spaces, thereby avoiding direct large-scale leakage and waste of coolant and avoiding large-scale splashing of coolant.

[0075] As the two butt-joint pipe sleeves 5 are continuously withdrawn, the through openings between the two drainage pipes 501 and the two butt-joint pipe sleeves 5 are separated from the two rubber sealing sleeves 1012 and opened. At this time, the two butt-joint pipe sleeves 5 can directly discharge the leaked coolant collected in their internal sealed spaces into the coolant tank for recycling through the two hoses connected thereto;

[0076] Note: When collecting and draining the leaked coolant, it is necessary to ensure that the through-port and the rubber sealing sleeve 1012 are separated and opened, but the connecting pipe sleeve 5 should not be completely separated from the rubber sealing sleeve 1012; when disassembling and assembling the upper mold body 1, the upper mold body 1 should be slid down and docked against the lower mold, and the lower mold should be used to support the upper mold body 1.
