Description

Technical Field

[0001] The invention relates to an injection mold, in particular to a detachable injection mold and a use method thereof. Background Art

[0002] The removable injection mold is mainly composed of a concave mold with a variable cavity composed of a concave mold plate, a concave mold assembly and a concave mold combination plate, and a convex mold with a variable core composed of a convex mold plate, a convex mold assembly, a convex mold combination plate, a cavity truncation assembly and a side truncation combination plate. The mold convex, concave mold and auxiliary molding system are coordinated and changed. A series of plastic parts of different shapes and sizes can be processed.

[0003] Mold trial refers to the test of the mold before mass production of the product. The mold trial is the same as the injection mold, but the difference is that the mold trial can be modified. During the mold trial, an external circulation pipeline is required. The liquid in the pipeline will take out the heat in the mold during the circulation process. However, there is a certain distance between the pipeline and the die. At this distance, there will definitely be a difference in the inlet and outlet temperatures of the pipeline, which will cause the die to be unable to be cooled evenly. At the same time, due to the particularity of the mold trial (because the product is not determined, the mold needs to be modified many times), the mold needs to be adjusted after a few products are made, and the pipeline needs to be removed from the mold during the adjustment process. Frequent disassembly leads to reduced efficiency during mold repair. Summary of the invention

When the bearing plate descends, the coolant does not contact the die, so that the coolant is cooled. When the bearing plate rises, the coolant is completely in contact with the side wall of the die, so that the die is evenly dissipated and the coolant cools the die.

[0020] 2. In the detachable injection mold and the method of using the same, when the supporting plate drives the liquid to move downward, the floating block separates from the liquid and drives one end of the connecting rod to descend by its own gravity, causing the other end to rise and push the ejector block through the straight rod.

[0042] In addition, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features. In the description of the present invention, the meaning of "plurality" is two or more, unless otherwise clearly and specifically defined.

[0043] First, please refer to Figure 1 and Figure 2 As shown, a detachable injection mold is provided, including a mold body 100 and a mounting platform 200, the mold body 100 includes a convex mold plate 110 and a concave mold plate 120, the concave mold plate 120 is mounted on the top of the mounting platform 200, one end of the top of the mounting platform 200 is fixedly provided with two round rods, the top of the round rods is fixedly connected to a top plate 210, the top of the top plate 210 is fixedly installed with a second hydraulic rod 211, the movable end of the second hydraulic rod 211 passes through the top plate 210, and the movable end is connected to the top of the convex mold plate 110, and then Figure 2 and 3 middle:

[0044] A convex mold 111 is fixedly provided at the bottom of the convex mold plate 110, and an injection tube 113 is penetrated through the convex mold plate 110 and the convex mold 111, so as to inject the molten plastic into the injection cavity 110A through the injection tube 113. A plurality of insertion rods 112 are also fixedly provided at the bottom of the convex mold plate 110. In order to store the liquid, a piston chamber 120A and a concave mold 124 are provided at the top of the concave mold plate 120, wherein, when the convex mold 111 moves into the concave mold 124, an injection cavity 110A is formed between the convex mold 111 and the concave mold 124, and a piston 121 is longitudinally slidably provided in the piston chamber 120A, and the side wall of the piston 121 is in contact with the inner wall of the piston chamber 120A to prevent the liquid in the piston chamber 120A from escaping to the top of the piston 121. At the same time, in order to improve the efficiency of resetting the piston 121, a reset spring (such as Figure 2As shown in the figure, the concave mold plate 120 is provided with an oil passage 122 communicating with the piston chamber 120A, one end of the oil passage 122 is connected with a first hydraulic rod 123, a liquid storage chamber 120B is provided in the concave mold plate 120, a coolant is provided in the liquid storage chamber 120B, the first hydraulic rod 123 is arranged in the liquid storage chamber 120B, a bearing plate 130 is fixedly provided on the top of the first hydraulic rod 123, and the force generated by the longitudinal movement of the convex mold plate 110 transports the liquid in the piston chamber 120A and the oil passage 122 to the first hydraulic rod 123, so that the first hydraulic rod 1 23 drives the carrying plate 130 to move. The carrying plate 130 is used to adjust the height of the coolant. During the mold closing process, the force of the downward movement of the convex mold plate 110 is used and the force is transmitted to the first hydraulic rod 123 through the liquid in the piston chamber 120A, so that the first hydraulic rod 123 drives the carrying plate 130 to move. When the carrying plate 130 descends, the coolant does not contact the die 124, so the coolant is cooled. When the carrying plate 130 rises, the coolant is completely in contact with the side wall of the die 124, so that the die 124 is evenly dissipated and the coolant cools the die 124.

[0045] When in use, the movable end of the second hydraulic rod 211 moves downward to drive the concave mold plate 120 to move downward, so that the male mold 111 enters into the female mold 124, and the insertion rod 112 enters into the piston chamber 120A, and then the melted plastic is injected into the injection cavity 110A through the injection tube 113. At the same time, the insertion rod 112 moves downward to push the piston 121, and the piston 121 moves downward to squeeze the liquid in the piston chamber 120A and the oil channel 122 into the first hydraulic rod 123. At this time, the movable end of the first hydraulic rod 123 rises and drives the bearing plate 130, and the bearing plate 130 moves upward to push the coolant in the liquid storage cavity 120B , so that the coolant is located on the side wall of the die 124; when the product in the injection cavity 110A is formed and solidified, the movable end of the second hydraulic rod 211 moves downward to drive the die plate 120 to rise. Since the contact surface between the punch 111 and the product is smaller than the contact surface between the die 124 and the product, and due to the factor of gravity, the product will be located on the side wall of the die 124, and the insert rod 112 will also leave the injection cavity 110A. At this time, the gravity of the coolant will drive the carrier plate 130 to move downward, causing the first hydraulic rod 123 to contract and transport the liquid inside it to the oil channel 122 and the piston chamber 120A, so as to reset the piston 121.

[0046] The second purpose of this embodiment is to provide a method for using a detachable injection mold, comprising the following method steps:

[0047] S1, the movable end of the second hydraulic rod 211 moves downward to drive the convex mold plate 110 to move downward, so that the convex mold 111 enters into the concave mold 124, and the insertion rod 112 enters into the piston chamber 120A;

[0048] S2, injecting the melted plastic into the injection cavity 110A through the injection tube 113;

[0049] S3. When the insertion rod 112 enters the piston chamber 120A, the insertion rod 112 moves downward to push the piston 121. The piston 121 moves downward to squeeze the liquid in the piston chamber 120A and the oil channel 122 into the first hydraulic rod 123. The movable end of the first hydraulic rod 123 rises and drives the supporting plate 130. The supporting plate 130 moves upward to push the coolant in the liquid storage chamber 120B, so that the coolant is located on the side wall of the die 124.

[0050] In the second embodiment, after the product is solidified, the contact surface between the male mold 111 and the product is smaller than the contact surface between the female mold 124 and the product, and the factor of gravity causes the product to be adsorbed on the inner wall of the female mold 124. The product still has a certain temperature after solidification, which is not convenient for manual operation. Therefore, Figure 3 and Figure 4 As shown:

[0051] The ejector 140 also includes a connecting rod 141. The connecting rod 141 is a telescopic structure. The connecting rod 141 is rotatably arranged on the outer wall of the bottom of the concave mold 124. A floating block 142 is arranged at the bottom of the connecting rod 141 near the side wall of the liquid storage chamber 120B. The floating block 142 is a hollow structure and is preferably made of aluminum. The hollow aluminum material can float on the liquid surface and has a certain weight to facilitate the pushing of the product. The other end of the connecting rod 141 is rotatably connected to a straight rod 143. Then, as shown in FIG. Figure 5 As shown, the straight rod 143 passes through the bottom of the die 124 and is longitudinally slidably connected to the die 124 . The top of the straight rod 143 is fixedly connected to a top block 144 . The bottom inner wall of the die 124 is provided with a receiving groove 145 , and the top block 144 is movably arranged in the receiving groove 145 .

[0052] When in use, the carrying plate 130 drives the liquid to move upward, so that the floating block 142 contacts the liquid and floats. The floating block 142 floats and drives one end of the connecting rod 141 to rise, while the other end of the connecting rod 141 (that is, the end located at the straight rod 143) will be lowered through the rotating connection with the bottom of the die 124. At this time, the straight rod 143 moves downward and drives the top block 144, so that the top block 144 is located in the receiving groove 145. When the carrying plate 130 drives the liquid to move downward, the floating block 142 is separated from the liquid and drives one end of the connecting rod 141 to descend through its own gravity, causing the other end (located at one end of the straight rod 143) to rise, and push the top block 144 through the straight rod 143. The top block 144 pushes the product in the injection cavity 110A to separate the product from the inner wall of the die 124.

[0053] In the third embodiment, considering that the coolant itself absorbs a lot of heat when cooling the product in the injection molding cavity 110A, after multiple injection molding of the product, the coolant temperature is high, which affects the efficiency of the subsequent injection molding process. Figure 6 As shown, the concave mold plate 120 has a diversion cavity 120C at both ends of the liquid storage cavity 120B, and the side wall of the diversion cavity 120C is provided with an overflow port 150 and a drain port 151 that communicate with the liquid storage cavity 120B. When the carrier plate 130 rises to the concave mold 124 (specifically as shown in FIG. Figure 7 When the carrier plate 130 reaches the bottom of the support plate 130, part of the liquid on the top of the support plate 130 flows into the diversion chamber 120C through the overflow port 150. Drain ports 151 are fixedly provided at both ends of the support plate 130. The baffle plate 152 blocks the drain ports 151 during the rising process of the support plate 130.

[0054] The specific working principle is that after the carrier plate 130 rises to the bottom of the die 124, the baffle 152 blocks the drain port 151, and the liquid level of the coolant at the top is higher than the overflow port 150. At this time, this part of the liquid flows into the diverter cavity 120C through the overflow port 150, so that this part of the coolant does not participate in the cooling work. When the carrier plate 130 descends, the carrier plate 130 drives the liquid and the baffle 152 to move downward. After the baffle 152 moves downward, the drain port 151 is opened. At this time, the liquid in the diverter cavity 120C flows into the top of the carrier plate 130 through the drain port 151 to cool the working coolant.

[0055] Fourth embodiment: This embodiment is implemented on the basis of the third embodiment. Considering that after part of the cooling liquid is diverted to the diverting chamber 120C, although this part of the cooling liquid does not participate in the work of cooling the product, since the diverting chamber 120C is a sealed environment, it is not conducive to cooling this part of the cooling liquid. Therefore, Figure 7 As shown, an air pipe 170 is provided in the concave template 120, and the bottom end of the air pipe 170 is connected to the liquid storage chamber 120B, and the top end of the air pipe 170 passes through the diverter chamber 120C and the concave template 120. When the air pipe 170 transports external gas to the liquid storage chamber 120B, the coolant in the diverter chamber 120C exchanges heat with the gas in the air pipe 170. During operation, the supporting plate 130 moves upward to generate a negative pressure in the liquid storage chamber 120B. Therefore, under the action of the negative pressure, the external gas is sucked into the liquid storage chamber 120B through the air pipe 170. In this process, the external gas cools down the liquid in the diverter chamber 120C through the air pipe 170, thereby improving the cooling efficiency of the gas in the diverter chamber 120C.

[0056] In the fifth embodiment, considering that grinding (grinding the side wall of the male mold 111 or the female mold 124) often occurs during the mold trial process, and it is necessary to clean it after grinding. In order to replace the manual cleaning work, this embodiment is implemented on the basis of the second embodiment. First, as Figure 4 As shown, a groove is provided at the top of the connecting rod 141, a guide plate 146 is fixedly provided on the side wall of the straight rod 143, and a through opening is provided at the bottom of the guide plate 146 at the end of the connecting rod 141. Figure 5 The guide plate 146 is located below the concave mold 124 , a water leakage port is opened through the bottom of the receiving groove 145 , and one end of the connecting rod 141 close to the floating block 142 is located at the drainage port 151 .

[0057] Working principle, such as Fig. 9 As shown, liquid is poured into the die 124, and the liquid flushes the impurities generated by grinding. Then, the liquid and impurities flow into the guide plate 146 through the leaking port, and flow into the groove through the opening in the guide plate 146. Since the float 142 is not in contact with the water surface, the float 142 drives the connecting rod 141 to tilt through gravity, and the tilted connecting rod 141 drains the liquid and impurities in the groove, so that the liquid and debris flow into the diversion chamber 120C through the drain port 151.

[0058] In addition, considering that when the liquid in the liquid storage chamber 120B enters the diverting chamber 120C through the overflow port 150, it will collide with the liquid in the diverting chamber 120C, causing the impurities in the diverting chamber 120C to flow in the liquid and easily be discharged into the liquid storage chamber 120B through the discharge port 151, Figure 6 As shown, a filter plate 160 is provided in the diverter chamber 120C, and the filter plate 160 is located above the drain port 151. When the supporting plate 130 rises, the coolant and impurities will enter the diverter chamber 120C through the overflow port 150. During this process, the coolant and impurities will first pass through the filter plate 160, and the filter plate 160 will block the impurities, so that the impurities cannot contact the liquid in the diverter chamber 120C, thereby preventing more impurities from being generated in the liquid storage chamber 120B.

[0059] Further, such as Figure 8 As shown, in order to facilitate the cleaning of impurities in the diverter cavity 120C, a cleaning port communicating with the diverter cavity 120C is opened on the side wall of the concave template 120, and a cover plate 180 is inserted and matched at the cleaning port.

[0060] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the present invention and are not intended to limit the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention. The scope of protection of the present invention is defined by the attached claims and their equivalents.
