Description

Technical Field

[0001] The invention relates to the technical field of a rubber mold for diving into a slider, and in particular to a rubber mold for diving into a slider. Background Art

[0002] After recycling, plastic waste can be turned into rubber, which can then enter the rubber mold inside the slider. Plastic parts with complex geometric shapes or internal structures can be produced through the rubber mold inside the slider, and there is no trace of the rubber mouth, so there is no need to trim the rubber mouth later, which improves production capacity and efficiency. The rubber mold inside the slider is also convenient for ejecting the plastic waste generated in the gate channel, which is convenient for recycling the plastic waste in the later stage. The processed plastic waste can be injected into plastic parts through the mold again, thereby avoiding the waste of plastic waste. For example, the patent name disclosed in the prior art with the announcement number "CN220883206U" is "A mold with a latent glue feeding mechanism in a slider", which discloses that the right slider will drive the gate ejector inserted therein to slide horizontally, and the sliding groove on the movable mold core can allow the gate ejector to slide horizontally. The gate ejector is placed in the V-shaped groove at the upper end of the adapter block through the V-shaped lower end, so that the gate ejector can slide horizontally on the adapter block and will not fall off the adapter block, thereby realizing the gate ejector sliding horizontally with the right slider. The ejector plate and the ejector bottom plate are moved without interfering with the sliding of the right slider. Then, the ejector rod of the injection molding machine drives the ejector bottom plate and the ejector panel to move upward through the reset connecting rod, thereby driving the discharge ejector and the adapter block to move upward. The adapter block drives the gate ejector to move upward, so that the discharge ejector and the gate ejector eject the molded product and the runner in the latent gate respectively. Then, when the ejector panel moves upward, the reset spring squeezed by the reset is reset to drive the ejector panel and the ejector bottom plate to move downward, thereby driving the discharge ejector, the adapter block and the gate ejector to reset. , the demoulding of the product is completed, and the patent name disclosed in the prior art with the publication number "CN114368117A" is "a latent glue feeding mechanism of a mold", which discloses that the latent glue feeding mechanism of the mold first sets the vertical flow channel and the latent flow channel on the slider, and the vertical flow channel and the latent flow channel are connected to each other as a whole and form an inclined angle, wherein the vertical flow channel and the latent flow channel have the function of diverting and buffering the rubber material, and secondly, the rubber material in the latent flow channel directly enters the glue feeding support sheet channel from the head of the slider, and then enters the glue feeding molding cavity of the product from the glue feeding support sheet channel, and then, when the latent glue feeding mechanism of the mold is in the mold opening state, the vertical flow channel and the latent flow channel directly withdraw backward with the slider, and after withdrawing a certain distance, the waste ejector directly ejects the vertical flow channel, directly avoiding the flow channel from being stuck and the mold from being crushed, and using the latent glue feeding mechanism of the mold of the present invention, not only the problem that the material head is easily stuck between the mold core and the slider and the mold is damaged is solved, the mold maintenance cost is reduced, and the product quality and the production efficiency of the mold are improved.

[0003] When the above-mentioned slider internal rubber-inserting mold in the prior art is in use, although the vertical flow channel and the latent flow channel have the function of diverting and buffering the rubber, the rubber in the latent flow channel directly enters the rubber inlet support plate channel from the head of the slider, and enters the product's rubber inlet molding cavity from the rubber inlet support plate channel. However, in this process, if the temperature around the vertical flow channel and the latent flow channel is not controlled, the rubber will be affected by the low temperature and cause poor fluidity, and then the rubber will block the gate channel, resulting in difficulty in the glue injection of the slider, requiring subsequent manual processing or the opening of the mold to inject glue at three-plate mold points, which makes the product cost higher. Therefore, we propose a rubber-inserting mold suitable for the slider to solve the above-mentioned problems. Summary of the invention

The specific contents are as follows: The slider body can be directly used for internal latent injection of glue, and the main channel is lighter, which simplifies the mold structure, reduces the mold and product costs, and does not require manual processing in the later stage, thereby improving production capacity and efficiency. At the same time, the temperature distribution in the slider body is uniform through the temperature control component, which will not affect the fluidity of the rubber compound.

[0016] By moving the slider body, the upper part of the waste ejector pin contacts the vertical gate channel, and then the waste ejector pin pushes the main channel in the vertical gate channel to move upward, so that the main channel is separated, thereby facilitating the ejection of the main channel of the plastic waste, so that the main channel of the plastic waste can be recycled and reused later. The processed plastic waste can be injection molded into plastic parts through the mold again, thereby avoiding the waste of plastic waste; By optimizing the shape and size of the side gate channel and the vertical gate channel, the pressure loss of the rubber compound in the side gate channel and the vertical gate channel is reduced. By adjusting the position and number of the side gate channels, it is ensured that the rubber compound can evenly fill the cavity, balance the filling pressure, and reduce gate marks. By setting the groove, the contact area between the inclined guide column and the slider seat can be reduced, and then the friction between the inclined guide column and the slider seat can be reduced, thereby avoiding affecting the movement of the slider seat. At the same time, the lubricating oil can be automatically discharged through the discharge hole, thereby further reducing the friction between the inclined guide column and the slider seat, making it easier for the inclined guide column to slide well in the slider seat.

DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the 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.

For the specific structure, please refer to the attached Figure 1-Figure 7 As shown, it includes an upper support plate 1 and an upper template 5 installed thereunder, and a lower template 6 is arranged below the upper template 5, and a glue inlet 4 for the recycled plastic waste to enter is opened inside the upper support plate 1 and the upper template 5, and the four corners of the lower surface of the upper support plate 1 are connected to the lower template 6 through guide limit assemblies, and a slider seat 11 and a slider body 12 are slidably connected in the groove opened inside the upper surface of the lower template 6, and a slider body 12 for internal glue injection is installed on the left side of the slider seat 11, and an inclined guide column 13 is installed inside the upper template 5, and the lower end of the inclined guide column 13 is inserted into the slider seat 11 for controlling the horizontal movement of the slider seat 11, and a cavity 61 is opened in the lower template 6 on the left side of the slider body 12, and a temperature control component is installed in the slider body 12.

[0021] The guide limit assembly includes a guide rod 2 installed at the four corners of the lower surface of the upper support plate 1, and a guide sleeve 3 installed at the four corners of the upper surface of the lower template 6. The guide sleeve 3 is slidably connected to the guide rod 2. The upper surface of the slider body 12 is provided with a latent gate channel 18, a side gate channel 19 and a vertical gate channel 20. The lower part of the latent gate channel 18 is connected to the vertical gate channel 20. The lower left side of the latent gate channel 18 is connected to the inclined side gate channel 19. The latent gate channel 18, the side gate channel 19 and the vertical gate channel 20 are provided with a main channel 17 for plastic waste. A connecting plate 7 is installed below the lower template 6. Side support plates 8 are symmetrically fixed below the connecting plate 7. The bottom surface of the side support plate 8 is connected to a bottom plate 9. The top of the bottom plate 9 is connected to an ejector plate 10. The ejector plate 10 is arranged on the two side support plates. In the space between the plates 8, a waste ejector pin 101 and a product ejector pin 102 are fixed above the ejector plate 10, a cavity 61 is correspondingly provided above the product ejector pin 102, a vertical gate channel 20 is correspondingly provided above the waste ejector pin 101, the right side surface of the slider body 12 is connected to the interior of the lower template 6 through a spring column 14, the spring column 14 is composed of a manual telescopic rod and a reset spring, the outer side of the manual telescopic rod is nested and connected with a reset spring, the temperature control component includes a flow groove 121 opened in the slider body 12, the open end of the flow groove 121 is internally threaded and sealed with a sealing plug 122, the internal groove of the slider body 12 is embedded with a water inlet pipe 15 and a water outlet pipe 16, the right ends of the water inlet pipe 15 and the water outlet pipe 16 both pass through the right side surface of the lower template 6, and the left ends of the water inlet pipe 15 and the water outlet pipe 16 are both sealed and inserted into the flow groove 121.

[0022] First, after the mold is closed by the injection molding machine, a closed cavity 61 is formed. The slider seat 11 and the slider body 12 are moved to a predetermined position under the drive of the inclined guide column 13. The external rubber enters the latent gate channel 18, the side gate channel 19 and the vertical gate channel 20 through the rubber inlet 4 (the external rubber is the rubber produced by recycling plastic waste). Then, the rubber flows evenly into the cavity 61 through the two side gate channels 19 for molding. By optimizing the shape and size of the side gate channel 19 and the vertical gate channel 20, the pressure loss of the rubber in the side gate channel 19 and the vertical gate channel 20 can be reduced to ensure that the rubber can be evenly The cavity 61 is filled evenly, the filling pressure is balanced, and the gate marks are reduced. After a period of cooling and molding, the mold is opened, so that the upper support plate 1 and the upper mold plate 5 drive the inclined guide column 13 to move upward. At this time, the lower end of the inclined guide column 13 moves upward in the slider seat 11. When the inclined guide column 13 is separated from the slider seat 11, the slider seat 11 moves outward through the push of the inclined guide column 13. At this time, the spring column 14 resets and drives the slider seat 11 to move outward stably. The spring column 14 is a manual telescopic rod and the outer side is provided with a reset spring setting, which is convenient for ensuring the stable movement of the slider seat 11, and can limit the slider seat 11, and at the same time drive the main channel 17 to move outward, moving 6.0mm later, at this time, the upper end of the waste ejector 101 coincides with the vertical gate channel 20, and the electric push rod drives the ejector plate 10, the waste ejector 101 and the product ejector 102 to move upward, the waste ejector 101 pushes the main channel 17 upward, and the product ejector 102 pushes the molded product in the cavity 61 upward, so that the main channel 17 is separated from the slider body 12 to complete a molding action. The main channel 17 pushed out by the waste ejector 101 is waste, also known as runner condensate, and the main channel 17 is lighter, which simplifies the mold structure, reduces the mold and product costs, does not require manual processing in the later stage, and improves production capacity and efficiency. Therefore, it is easy to eject and demold the main channel of plastic waste, so that the main channel of plastic waste can be recycled and reused in the later stage. The processed plastic waste can be injection molded into plastic parts through the mold again, thereby avoiding the waste of plastic waste. (Since the inclination angle of the side gate channel 19 is usually controlled between 5° and 15° , because the angle is too small, when the main channel 17 is ejected later, the ejection resistance of the side gate channel 19 will be small, and the main channel 17 is made of plastic. Plastic waste has elastic deformation ability at the ejection temperature (about 60-80℃), so the inclined end of the main channel 17 corresponding to the side gate channel 19 will be slightly bent and deformed when subjected to upward tension and move upward together. The rebound force generated after deformation helps to detach from the side gate channel 19. The creep characteristics of plastic prevent permanent deformation when subjected to short-term force. At the same time, the latent gate channel 18, the side gate channel 19 and the vertical gate channel 20 can be polished or titanium-plated to reduce mold sticking. Therefore, in summary, when the waste ejector 101 pushes part of the main channel 17 in the vertical gate channel 20 upward, it will also push the side gate channel 19 and the corresponding part of the main channel 17 in the latent gate channel 18 upward, and will not affect the ejection operation of the entire main channel 17). .

[0023] At the same time, another two groups of waste ejector pins 101 can be arranged at corresponding positions below the latent gate channel 18, so that the entire main channel 17 can be well ejected upwards through the cooperation of the four groups of waste ejector pins 101.

[0024] At the same time, when the external glue enters the latent gate channel 18, the side gate channel 19 and the vertical gate channel 20 through the glue inlet 4, if the temperature sensor in the slider body 12 detects a low temperature, in order to prevent the glue in the latent gate channel 18, the side gate channel 19 and the vertical gate channel 20 from solidifying due to the low temperature, warm water from the outside can be allowed to enter the water inlet pipe 15, the circulation groove 121 and the water outlet pipe 16, and then be discharged through the water outlet pipe 16. Therefore, the temperature in the slider body 12 can be heated, and the temperature distribution in the slider body 12 can be uniform, avoiding affecting the fluidity of the glue, thereby avoiding blockage in the latent gate channel 18 and the side gate channel 19, and then no manual processing or three-plate mold opening is required to point glue in, thereby reducing product costs.

[0025] Embodiment 2: This embodiment is suitable for the rubber mold that is inserted into the slider. On the basis of Embodiment 1, another structure of the temperature control component is disclosed. The specific structure is shown in the attached Figure 8-Figure 11 As shown, the temperature control assembly includes a first enclosure frame 21 and a second enclosure frame 22 installed on the bottom surface of the upper template 5, the lower parts of the first enclosure frame 21 and the second enclosure frame 22 are inserted into the grooves opened on the upper surface of the slider body 12, the interiors of the first enclosure frame 21 and the second enclosure frame 22 are both hollow, and the spaces inside the first enclosure frame 21 and the second enclosure frame 22 are connected.

[0026] When the external glue enters into the latent gate channel 18, the side gate channel 19 and the vertical gate channel 20 through the glue inlet 4, if the temperature sensor in the slider body 12 detects that the temperature is low, the external warm water can be introduced into the second enclosure 22 and the first enclosure 21 which are hollow and connected inside through the pipe. Therefore, the first enclosure 21 can heat the temperature inside the slider body 12 to make the temperature distribution inside the slider body 12 uniform. The second enclosure 22 can heat the outer side of the glue inlet 4 to avoid affecting the fluidity of the glue, thereby avoiding blockage in the latent gate channel 18 and the side gate channel 19, so as to facilitate the internal latent glue injection operation.

[0027] Embodiment 3: This embodiment is suitable for the slide into the rubber mold. On the basis of embodiment 1, the friction between the slide seat 11 and the inclined guide column 13 can be reduced, which not only facilitates the service life of the inclined guide column 13, but also improves the smoothness of the movement of the inclined guide column 13. For specific structure, please refer to the attached Figure 12-14As shown, a piston mechanism 135 is fitted and connected in a groove opened inside the lower part of the inclined guide column 13, and the lower end of the piston mechanism 135 is connected to the control column 132. A connecting spring 136 is nested and connected to the lower outer side of the piston mechanism 135. A flow groove 134 is opened inside the outer side surfaces of the inclined guide column 13 and the control column 132. The flow groove 134 in the inclined guide column 13 is arranged in a "7" shape. The space of the flow groove 134 in the inclined guide column 13 is connected to the space in the groove opened in the lower part of the inclined guide column 13. The flow groove 134 in the column 13 is connected with the flow groove 134 in the control column 132 below. The outer sides of the inclined guide column 13 and the control column 132 are provided with discharge holes 133 connected with the inside of the flow groove 134. A one-way delivery pipe 137 is installed through the upper interior of the inclined guide column 13. A piston mechanism 135 is provided at the lower end of the one-way delivery pipe 137 with a one-way valve installed inside. The outer sides of the inclined guide column 13 and the control column 132 are provided with grooves 131, and the grooves 131 and the flow grooves 134 are arranged alternately.

[0028] The outer sides of the inclined guide column 13 and the control column 132 are provided with grooves 131, so as to reduce the contact area between the inclined guide column 13 and the control column 132 and the slider seat 11, and then reduce the friction between the inclined guide column 13 and the control column 132 and the slider seat 11. At the same time, when the lower end of the inclined guide column 13 moves into the slider seat 11, the lower end of the control column 132 below the inclined guide column 13 abuts against the inside of the lower template 6. At this time, when the lower end of the inclined guide column 13 continues to move into the slider seat 11, the piston mechanism 135 above the control column 132 will press the inclined guide column 13. The lubricating oil in the groove inside is pushed, so that the lubricating oil in the inclined guide column 13 enters the discharge hole 133 through the flow groove 134 in the shape of a "7", and then the lubricating oil is discharged through the discharge hole 133, so that the lubricating oil is smeared on the outside of the inclined guide column 13 and the control column 132, thereby facilitating lubrication of the outside of the inclined guide column 13 and the control column 132, thereby further reducing the friction between the outside of the inclined guide column 13 and the control column 132 and the inside of the slider seat 11, so that the inclined guide column 13 can move up and down well to control the slider seat 11 to move horizontally.

[0029] When the inclined guide column 13 moves upward, the stored force of the connecting spring 136 can drive the piston mechanism 135 and the control column 132 to automatically move downward for a distance. At this time, a certain amount of lubricating oil is injected into the inclined guide column 13 through the one-way delivery pipe 137 for the next use. A one-way valve is installed in the one-way delivery pipe 137 to complete a series of tasks.

[0030] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
