Description

Technical Field

[0001] This utility model relates to the field of mold technology, specifically to a mold that facilitates material discharge. Background Technology

[0002] In modern manufacturing, molds are key tools for producing various products and are widely used in many fields such as automobile manufacturing, electronic equipment production, and plastic product processing. The performance of molds directly affects the production efficiency and quality of products.

[0003] Based on the above, the inventors have discovered the following problems: In the large-scale production of plastic injection molded parts, the molding of various plastic products, such as plastic shells and plastic containers, is inseparable from molds. Taking the production of common plastic shells as an example, after the mold is formed, the shell fits tightly against the inner wall of the mold cavity. Due to a lack of experience, novice workers often find it difficult to accurately find the point of leverage when demolding. When using tools such as pry bars and suction cups, their techniques are clumsy and their force is uneven. Not only is the demolding speed slow, but improper operation can also easily cause the shell to be scratched or deformed. Due to the large differences in demolding efficiency among workers, the overall production progress is extremely unstable, which affects the company's ability to deliver orders on time.

[0004] Therefore, in view of this, we will study and improve the existing structure and its shortcomings to provide a mold that facilitates material discharge, in order to achieve a more practical purpose. Utility Model Content

[0005] The purpose of this utility model is to provide a mold that facilitates material discharge, in order to solve the problem mentioned in the background art that after the mold is formed, the outer shell and the inner wall of the mold cavity are tightly fitted. Novice workers often have difficulty finding the right point of force when demolding due to lack of experience. When using tools such as pry bars and suction cups, their techniques are clumsy and their force is uneven. This not only results in slow demolding speed, but also easily leads to scratches and deformation of the outer shell due to improper operation.

[0006] In view of the above problems, the technical solution proposed by this utility model is as follows:

[0007] A mold for easy material discharge includes a lower mold base, an upper mold base, and a discharge mechanism. The lower mold base includes a base with slots on both sides of its upper surface. A mold cavity is formed at the upper end of the base, and a pair of reserved slots are formed at the bottom end of the mold cavity. The base has an internal receiving cavity. The upper mold base includes a top seat with insert rods fixedly installed on both sides of its bottom end. The insert rods are inserted into the slots. The discharge mechanism includes a pair of top blocks and a pair of sliding rods. A top rod is installed at the bottom end of each pair of top blocks. The pair of top rods are movably inserted into the center of the pair of reserved slots with a clearance fit. The pair of sliding rods are respectively arranged on both sides of the receiving cavity. A lifting plate is slidably installed between the pair of sliding rods. The bottom ends of the pair of top rods are connected to the upper surface of the lifting plate.

[0008] Furthermore, each of the slide rods is fitted with a spring at its bottom end, and the upper and lower ends of the spring are respectively connected to the bottom end of the lifting plate and the bottom end of the accommodating cavity.

[0009] The beneficial effect of adopting the above-mentioned further solution is that the spring sleeved at the bottom of the slide bar is connected to the bottom of the lifting plate and the bottom of the accommodating cavity at its upper and lower ends, respectively. When the mold is closed, the spring is compressed and stores elastic potential energy. When the mold is opened, the spring releases elastic potential energy, pushes the lifting plate to move upward, and then drives the top block to push the molded workpiece out of the mold cavity, realizing automatic material discharge and improving material discharge efficiency.

[0010] Furthermore, a first buffer pad is installed at the bottom end of each insertion rod, and a second buffer pad is installed on both sides of the upper end face of the lifting plate, with the bottom end of the first buffer pad abutting against the upper end of the second buffer pad.

[0011] The beneficial effect of adopting the above-mentioned further solution is that the first buffer pad at the bottom of the insert rod and the second buffer pads on both sides of the upper surface of the lifting plate abut against each other. During the mold closing process, the buffer pads can reduce the impact force between the insert rod and the lifting plate, reduce the wear of mold components, extend the service life of the mold, and also reduce the noise generated during mold closing.

[0012] Furthermore, the discharge mechanism also includes a pair of first mounting seats, the bottom ends of which are respectively connected to the two sides of the bottom end of the accommodating cavity. A pair of second mounting seats are fixedly installed at the bottom end of the lifting plate, and damping rods are hinged between the second mounting seats and the first mounting seats through pins.

[0013] The beneficial effect of adopting the above-mentioned further solution is that the first mounting seat of the discharge mechanism is installed on both sides of the bottom end of the receiving cavity, and the second mounting seat is fixed to the bottom end of the lifting plate. A damping rod is hinged between them by a pin. The damping rod can provide damping effect when the lifting plate moves, making the process of the top block ejecting the workpiece more stable, avoiding damage to the workpiece due to excessive ejection speed, and ensuring the quality of the workpiece.

[0014] Furthermore, positioning sleeves are installed at the four corners of the upper surface of the base, and positioning rods are installed at the four corners of the bottom of the top seat. The positioning sleeves are inserted into the positioning rods.

[0015] The beneficial effect of adopting the above-mentioned further solution is that the positioning sleeves at the four corners of the upper end face of the base are inserted into the positioning rods at the four corners of the bottom end of the top seat. During the mold closing process, the positioning sleeves and positioning rods can accurately guide the relative position of the upper mold seat and the lower mold seat, ensuring that the mold core can accurately enter the mold cavity and improve the forming accuracy of the mold.

[0016] Furthermore, a mold core is installed at the bottom end of the top seat, and feed ports are provided on both sides of the bottom end of the mold core. The beneficial effect of adopting the above-mentioned further solution is that the mold core at the bottom end of the top seat cooperates with the mold cavity to form the workpiece, and the feed ports on both sides of the bottom end of the mold core can allow the material to enter the mold cavity evenly, ensuring the quality of workpiece forming and avoiding defects in the workpiece due to uneven material distribution.

[0017] Furthermore, an injection port is installed at the upper end of the top seat, and the bottom end of the injection port is connected to a pair of feed ports through a three-way pipe.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the injection port at the upper end of the top seat is connected to a pair of feed ports through a three-way pipe. The operator can inject the material into the mold through the injection port. The design of the three-way pipe ensures that the material can enter the mold cavity simultaneously and evenly through the two feed ports, thereby improving the efficiency of material injection and molding quality.

[0019] Compared with the prior art, the beneficial effects of this utility model are as follows: the mold that facilitates material discharge has a lower mold base that provides support for the entire mold, a slot that connects to the upper mold base's insert rod, allowing the insert rod to be inserted into the slot when the top seat and base are closed, thereby driving the lifting plate to press down, a mold cavity for forming workpieces, a reserved slot for providing installation space for the top block, and a receiving cavity for installing the discharge mechanism. The top seat of the upper mold base and the lower mold base cooperate to complete the opening and closing action of the mold. The top block of the discharge mechanism, driven by the ejector rod, can eject the formed workpiece from the mold cavity, facilitating material discharge. The lifting plate slides on the slide rod, driving the ejector rod and the top block to move, thereby lifting the workpiece from the mold cavity for easy handling by the user.

[0026] Please see Figure 1 - Figure 4This utility model provides a technical solution: a mold for easy material discharge, including a lower mold base 1, an upper mold base 2, and a material discharge mechanism 3. The lower mold base 1 includes a base 101, with slots 103 on both sides of the upper end surface of the base 101, a mold cavity 104 at the upper end of the base 101, and a pair of reserved slots 105 at the bottom end of the mold cavity 104. The interior of the base 101 is provided with a receiving cavity 106. The upper mold base 2 includes a top seat 201, and the top seat 201... Insert rods 204 are fixedly installed on both sides of the bottom end, and the insert rods 204 are inserted into the slots 103; the discharge mechanism 3 includes a pair of top blocks 301 and a pair of sliding rods 302. Each of the bottom ends of the pair of top blocks 301 is equipped with a top rod 309, and the pair of top rods 309 are movably inserted into the center of a pair of reserved slots 105. The top blocks 301 and the reserved slots 105 are fitted with a clearance. The pair of sliding rods 302 are respectively arranged on both sides of the receiving cavity 106, and the pair of sliding rods 302 slide together. A lifting plate 303 is dynamically installed. The bottom ends of a pair of push rods 309 are connected to the upper end face of the lifting plate 303. The base 101 of the lower mold base 1 provides support for the entire mold. The slot 103 is inserted into the insertion rod 204 of the upper mold base 2, so that when the top seat 201 and the base 101 are closed, the insertion rod 204 can be inserted into the inside of the slot 103, thereby driving the lifting plate 303 to press down. The mold cavity 104 is used to form the workpiece, and the reserved groove 105 is for the top block 301. An installation space is provided, and the receiving cavity 106 is used to install the discharge mechanism 3. The top seat 201 of the upper mold base 2 cooperates with the lower mold base 1 to complete the opening and closing action of the mold. The top block 301 of the discharge mechanism 3, driven by the top rod 309, can push the molded workpiece out of the mold cavity 104 for easy discharge. The lifting plate 303 slides on the slide rod 302, driving the top rod 309 and the top block 301 to move, thereby lifting the workpiece out of the mold cavity 104 for easy handling by the user. The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative labor are within the protection scope of the present utility model.

[0027] Please see Figure 1 - Figure 4A pair of sliding rods 302 are each fitted with a spring 305 at their bottom ends. The upper and lower ends of the springs 305 are connected to the bottom ends of the lifting plate 303 and the accommodating cavity 106, respectively. A pair of insert rods 204 are each fitted with a first buffer pad 205 at their bottom ends. A second buffer pad 304 is fitted on both sides of the upper surface of the lifting plate 303. The bottom ends of the first buffer pads 205 abut against the upper ends of the second buffer pads 304. The discharge mechanism 3 also includes a pair of first mounting seats 306 and a pair of first mounting bases 306. The bottom ends of the mounting base 306 are connected to both sides of the bottom end of the accommodating cavity 106. A pair of second mounting bases 308 are fixedly installed at the bottom end of the lifting plate 303. The second mounting bases 308 and the first mounting base 306 are both hinged with damping rods 307 by pins. The spring 305 sleeved at the bottom end of the slide rod 302 is connected at its upper and lower ends to the bottom end of the lifting plate 303 and the bottom end of the accommodating cavity 106, respectively. When the mold is closed, the spring 305 is compressed, storing elastic potential energy, and the mold is opened. When the spring 305 releases its elastic potential energy, it pushes the lifting plate 303 upward, which in turn drives the top block 301 to eject the molded workpiece from the mold cavity 104, realizing automatic material discharge and improving material discharge efficiency. The first buffer pad 205 at the bottom of the insert rod 204 and the second buffer pads 304 on both sides of the upper end face of the lifting plate 303 abut against each other. During the mold closing process, the buffer pads can reduce the impact force between the insert rod 204 and the lifting plate 303, reduce the wear of mold components, extend the service life of the mold, and also reduce the noise generated during mold closing. The first mounting seat 306 of the discharge mechanism 3 is installed on both sides of the bottom end of the accommodating cavity 106, and the second mounting seat 308 is fixed to the bottom end of the lifting plate 303. A damping rod 307 is hinged between them by a pin. The damping rod 307 can provide damping effect when the lifting plate 303 moves, making the process of the top block 301 ejecting the workpiece more stable, avoiding damage to the workpiece due to excessive ejection speed, and ensuring the quality of the workpiece.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1 - Figure 4Positioning sleeves 102 are installed at the four corners of the upper end face of the base 101, and positioning rods 202 are installed at the four corners of the bottom end of the top seat 201. The positioning sleeves 102 and the positioning rods 202 are inserted into each other. A mold core 203 is installed at the bottom end of the top seat 201. The bottom end of the mold core 203 has inlet ports 206 on both sides. An injection port 4 is installed at the upper end of the top seat 201. The bottom end of the injection port 4 is connected to a pair of inlet ports 206 through a three-way pipe. The positioning sleeves 102 at the four corners of the upper end face of the base 101 are inserted into the positioning rods 202 at the four corners of the bottom end of the top seat 201. During the mold closing process, the positioning sleeves 102 and the positioning rods 202 can accurately guide the relative position of the upper mold base 2 and the lower mold base 1. The mold core 203 is positioned to ensure that it can accurately enter the mold cavity 104, thereby improving the molding accuracy of the mold. The mold core 203 at the bottom of the top seat 201 cooperates with the mold cavity 104 to form the workpiece. The feed ports 206 on both sides of the bottom of the mold core 203 can make the material enter the mold cavity 104 evenly, ensuring the quality of the workpiece molding and avoiding defects caused by uneven material distribution. The injection port 4 at the top of the top seat 201 is connected to a pair of feed ports 206 through a three-way pipe. The operator can inject the material into the mold through the injection port 4. The design of the three-way pipe ensures that the material can enter the mold cavity 104 simultaneously and evenly through the two feed ports 206, improving the efficiency of material injection and molding quality.

[0030] Specifically, the working principle of this easy-to-discharge mold is as follows: When the mold is closed, the operator controls the top seat 201 of the upper mold base 2 to move downward. The positioning rods 202 at the four corners of the bottom end of the top seat 201 are inserted into the positioning sleeves 102 at the four corners of the upper end face of the base 101, accurately guiding the relative position of the upper mold base 2 and the lower mold base 1, ensuring that the mold core 203 accurately enters the mold cavity 104. At the same time, the insert rods 204 on both sides of the bottom end of the top seat 201 are inserted into the slots 103 on the base 101. The first buffer pad 205 at the bottom end of the insert rod 204 abuts against the second buffer pad 304 on the lifting plate 303 to reduce the impact force. The insert rod 204 presses down and drives the lifting plate 303 to slide downward on the slide rod 302, compressing the spring 305 at the bottom end of the slide rod 302, so that the spring 305 stores elastic potential energy. At this time, the lifting plate 303 drives the top rod 309 to push the top rod 309 to push the top rod 303 to move downward. Block 301 descends into the reserved slot 105. Then, the operator injects material through the injection port 4 at the upper end of the top seat 201. The material enters the mold cavity 104 simultaneously and evenly from the feed ports 206 on both sides of the bottom end of the mold core 203 through the three-way pipe. The workpiece is formed with the cooperation of the mold core 203 and the mold cavity 104. When the mold is opened, the upper mold seat 2 moves upward, the insert rod 204 is pulled out from the slot 103, the compressed spring 305 releases elastic potential energy, and pushes the lifting plate 303 to slide upward on the slide rod 302. At the same time, the damping rod 307 between the first mounting seat 306 and the second mounting seat 308 in the discharge mechanism 3 provides damping effect, making the movement of the lifting plate 303 more stable. The lifting plate 303 drives the top block 301 through the push rod 309 to push the formed workpiece out of the mold cavity 104, making it convenient for the user to pick up the workpiece.
