Technical Field

[0001] The invention relates to the technical field of plastic molding or connection, and in particular to a mold glue feeding structure and a sealing plug capable of removing residual glue. Background Art

[0002] The mold is a common industrial manufacturing tool used to manufacture various plastic products. The mold needs to inject plastic materials and glue into the mold through the injection structure. The mold usually adopts a two-way injection system when injecting glue. The molten material is injected into the two sides of the injection mold through two injection ports to ensure the uniformity and consistency of the injection product molding. After the injection, the injection injection structure is sealed by a sealing plug. The technical enlightenment for the mold injection structure and the sealing plug; The following problems were found in the research on mold injection structure and sealing plug: During vacuum glue injection, glue is usually easily left at the inlet and outlet. To ensure that the product can be smoothly taken out of the mold after high-temperature baking, plugs need to be inserted into the inlet and outlet of the mold after the glue is injected, so as to take away the glue in the inlet and outlet after curing. However, the sealing plugs used in the existing glue injection structure can only seal the inside of the glue injection structure, and cannot quickly clean the glue on the inner wall of the glue injection structure after curing. At present, CN202311513644.6 in the prior art discloses a glue feeding structure for a mold and a multi-cavity mold, which discloses a glue feeding structure for the mold. The glue feeding structure of the invention includes a glue injection nozzle and a glue cutting mechanism. A glue injection port is provided at one end of the glue injection nozzle, and the glue cutting mechanism includes a first mounting plate, a second mounting plate is provided at the upper end of the first mounting plate, a receiving groove is provided in the first mounting plate, a piston is provided in the receiving groove, the piston divides the receiving groove into an upper cavity and a lower cavity, and a needle valve is provided at the lower end of the piston, and the needle valve can block or leave the glue injection port; a control valve, a main air inlet, a first output air hole and a second output air hole are provided on the second mounting plate, the first output air hole is connected to the upper cavity, and the second output air hole is connected to the lower cavity, and the control valve can control the main air inlet to be connected to the first output air hole or the second output air hole respectively, shortening the length of the airway hole, and reducing the number of openings, which can reduce the difficulty of designing and making the mold; it is also suitable for mold structures with more product cavities, thereby improving the processing efficiency of the mold; The present invention can mainly solve the problem that the sealing plug cannot quickly clean the glue on the inner wall of the glue inlet structure after solidification while sealing. Summary of the invention

[0003] In order to solve the above technical problems, the present invention provides a mold glue feeding structure and a sealing plug capable of removing residual glue, so as to solve the problems described in the above background technology.

[0004] The purpose and efficacy of the mold glue inlet structure and sealing plug capable of removing residual glue of the present invention are achieved by the following specific technical means: a mold glue inlet structure and sealing plug capable of removing residual glue, comprising a mold, a glue inlet cavity being provided inside the mold, a glue inlet pipe and a glue outlet pipe respectively penetrating the two ends of the glue inlet cavity, and plugs being movably nested and connected at the openings of the glue inlet pipe and the glue outlet pipe.

[0005] Furthermore, openings are provided at both ends of the glue inlet cavity, and a glue inlet pipe and a glue outlet pipe respectively pass through the openings.

[0006] Furthermore, the rubber inlet pipe and the rubber outlet pipe are provided in two groups, each group is provided with two, and the plugs are nested and docked with the rubber inlet pipe and the rubber outlet pipe respectively.

[0007] Furthermore, a blocking column is provided at one end of the plug close to the rubber inlet pipe and the rubber outlet pipe, and a scraper is surrounded at one end of the blocking column away from the plug.

[0008] Furthermore, the outer wall of the blocking column is provided with a slide groove, the number of which is matched with the scraper, and the blocking column is used in conjunction with the scraper.

[0009] Furthermore, the scraper is inclined at 45-90 degrees, and the end of the scraper away from the blocking column is in contact with the inner walls of the rubber inlet and outlet pipes. The scraper surrounds the outside of the blocking column, and the scrapers are in contact with each other for use. The scraper is made of deformable material, such as rubber.

[0010] Furthermore, one end of the scraper close to the blocking column is slidably connected to a bent rod, one end of the bent rod close to the slide groove is slidably connected to a slider, one end of the slider close to the inner wall of the slide groove is surrounded by a gasket, and the end of the gasket is penetrated by a suction cup.

[0011] Furthermore, the bending rod is arranged in an arc shape, and the sliding block is connected to the scraper through the bending rod.

[0012] Furthermore, when the scraper is inclined at 45°, the slider is at the end of the blocking column slot away from the scraper, and the slider slides inside the slot toward one end of the scraper, and the scraper is inclined at 90°.

[0013] Furthermore, the gasket ring is arranged in an arc shape, and the arched end of the arc is in contact with the inner wall of the slide groove of the blocking column, and a suction cup is provided at one end of the gasket ring away from the slide block.

[0014] Beneficial effects: 1. Manually embed the plug into the inlet and outlet pipes. Since the scraper is inclined at 45-90 degrees, the plug drives the plugging column to be embedded into the inlet and outlet pipes, and the scraper is inclined on the outside of the plugging column; 2. When the plug is taken out from the inside of the inlet and outlet pipes, the scraper is tilted at 90 degrees. At this time, the scraper can clean the inner wall of the inlet and outlet pipes during sliding, and clean the residual glue after curing inside the inlet and outlet pipes to avoid residual glue inside the inlet and outlet pipes after vacuum injection; 3. When the blocking column is embedded in the rubber inlet and outlet pipes, the scraper is tilted toward one end of the blocking column, and the scraper is squeezed to one end of the slider through the bent rod, and the gasket is deformed. At this time, the gasket can increase the friction between the slider and the inner wall of the slide groove through the suction cup, thereby preventing the slider from sliding inside the slide groove of the blocking column. At this time, the plug and the blocking column are quickly embedded in the rubber inlet and outlet pipes, and the inner wall of the scraper fits with the inner wall of the rubber inlet and outlet pipes. At this time, the scraper cannot tilt and swing, and the scraper tilt angle is 45°. The scraper can form a seal on both ends of the glue inlet cavity to prevent glue from overflowing into the rubber inlet and outlet pipes; 4. When the plug is taken out from the inside of the glue inlet pipe and the glue outlet pipe, one end of the scraper rubs against the inner wall of the glue inlet pipe and the glue outlet pipe, and slides toward one end of the scraper by using the slider. At this time, the scraper is tilted 90° as a whole. The scraper can scrape the glue on the inner wall of the glue inlet pipe and the glue outlet pipe, so that this kind of sealing plug can form a block inside the glue inlet structure after the glue is injected inside the mold to prevent the glue inside the mold from overflowing. At the same time, after the sealing plug is taken out, the cured glue inside the glue inlet structure is scraped off. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. Example

[0026] As attached Figure 1 To Attachment Fig. 9 As shown: Embodiment 1: A mold glue inlet structure and sealing plug capable of removing residual glue, comprising a mold 1, wherein a glue inlet cavity 101 is provided inside the mold 1, and a glue inlet pipe 103 and a glue outlet pipe 104 are respectively passed through the two ends of the glue inlet cavity 101, and plugs 102 are movably nested and connected at the openings of the glue inlet pipe 103 and the glue outlet pipe 104; Wherein: a glue inlet cavity 101, both ends of which are provided with openings, and a glue inlet pipe 103 and a glue outlet pipe 104 respectively pass through the openings; The plug 102, the rubber inlet pipe 103 and the rubber outlet pipe 104 are provided in two groups, each group is provided with two plugs, and the plug 102 is nested and docked with the rubber inlet pipe 103 and the rubber outlet pipe 104 respectively; Wherein: after the glue inlet cavity 101 is vacuum-injected with glue through the glue inlet pipe 103, plugs 102 are respectively inserted into the inside of the glue inlet pipe 103 and the glue outlet pipe 104 to clean the residual glue after curing inside the glue inlet pipe 103 and the glue outlet pipe 104, so as to avoid residual glue inside the glue inlet pipe 103 and the glue outlet pipe 104 after vacuum injection, so as to ensure that the product can be smoothly taken out of the mold 1 after high-temperature baking; Example 2: Refer to the attached manual Figure 3-7 It can be seen that the difference between Example 2 and Example 1 is that a blocking column 2 is provided at one end of the plug 102 close to the rubber inlet pipe 103 and the rubber outlet pipe 104, and a scraper 201 surrounds one end of the blocking column 2 away from the plug 102; Among them: the blocking column 2, the outer wall of the blocking column 2 is provided with a slide groove, the number of the slide grooves is matched with the scraper 201, and the blocking column 2 is used in conjunction with the scraper 201; The scraper 201 is inclined at 45-90 degrees. The end of the scraper 201 away from the blocking column 2 is in contact with the inner wall of the rubber inlet pipe 103 and the rubber outlet pipe 104. The scraper 201 surrounds the outer side of the blocking column 2. The scrapers 201 are in contact with each other for use. The scraper 201 is made of a deformable material, such as rubber; The scraper 201 is inclined at 45-90 degrees. Figure 5 As shown; When the scraper 201 is inclined at 45°, the scraper 201 forms a sliding fit with the inner wall of the inlet pipe 103 and the outlet pipe 104, which facilitates the plugging column 2 to be embedded in the inlet pipe 103 and the outlet pipe 104. When the scraper 201 is inclined at 90°, the inner walls of the rubber inlet pipe 103 and the rubber outlet pipe 104 are cleaned during the sliding process of the scraper 201; Wherein: the plug 102 is manually embedded in the inside of the rubber inlet pipe 103 and the rubber outlet pipe 104. Since the scraper 201 is inclined at 45-90 degrees, after the plug 102 drives the blocking column 2 to be embedded in the inside of the rubber inlet pipe 103 and the rubber outlet pipe 104, the scraper 201 is inclined at the outside of the blocking column 2; When the plug 102 is taken out from the inside of the glue inlet pipe 103 and the glue outlet pipe 104, the scraper 201 is inclined at 90 degrees. At this time, the scraper 201 can clean the inner wall of the glue inlet pipe 103 and the glue outlet pipe 104 during the sliding process, and clean the residual glue after curing in the glue inlet pipe 103 and the glue outlet pipe 104, so as to avoid residual glue in the glue inlet pipe 103 and the glue outlet pipe 104 after vacuum injection. Example 3: Refer to the attached manual Figure 5-9 It can be seen that the difference between Example 3 and Example 1-2 is that the end of the scraper 201 close to the blocking column 2 is slidably connected to the bent rod 3, the end of the bent rod 3 close to the slide groove is slidably connected to the slider 301, the end of the slider 301 close to the inner wall of the slide groove is surrounded by a gasket 302, and the end of the gasket 302 is penetrated by a suction cup 303; Wherein: the curved rod 3 is arranged in an arc shape, and the slider 301 is connected to the scraper 201 through the curved rod 3; When the slider 301 and the scraper 201 are inclined at 45°, the slider 301 is at the end of the chute of the blocking column 2 away from the scraper 201, and the slider 301 slides inside the chute toward the end of the scraper 201, and the scraper 201 is inclined at 90°; When the scraper 201 is inclined at 45°, the slider 301 is at the end of the sliding groove of the blocking column 2 away from the scraper 201. At this time, the slider 301 cannot slide toward the end of the plug 102. Therefore, the slider 301 limits the inclination angle of the scraper 201 through the bent rod 3. Please refer to the attached manual for details. Figure 5 As shown; The gasket 302 and the suction cup 303, the gasket 302 is arranged in an arc shape, the arched end of the arc is in contact with the inner wall of the slide groove of the blocking column 2, and the suction cup 303 is arranged at one end of the gasket 302 away from the slider 301; The backing ring 302 is made of the same material as the scraper 201; The gasket 302 is arranged in an arc shape, and the arched end of the arc fits with the inner wall of the slide groove of the blocking column 2, which can reduce the contact area between the gasket 302 and the inner wall of the slide groove of the blocking column 2, thereby facilitating the sliding block 301 to slide inside the slide groove of the blocking column 2; The end of the gasket 302 away from the slider 301 is provided with a suction cup 303. When the plug 102 is embedded in the rubber inlet pipe 103 and the rubber outlet pipe 104, the scraper 201 tilts toward one end of the blocking column 2, and the scraper 201 is squeezed to one end of the slider 301 through the bending rod 3, and the gasket 302 is deformed. At this time, the gasket 302 can increase the friction between the slider 301 and the inner wall of the slide groove through the suction cup 303, thereby preventing the slider 301 from sliding inside the slide groove of the blocking column 2; Among them: when the blocking column 2 is embedded in the inside of the glue inlet pipe 103 and the glue outlet pipe 104, the scraper 201 is inclined toward one end of the blocking column 2, and the scraper 201 is squeezed to one end of the slider 301 through the bending rod 3, and the gasket 302 is deformed. At this time, the gasket 302 can increase the friction between the slider 301 and the inner wall of the slide groove through the suction cup 303, thereby preventing the slider 301 from sliding inside the slide groove of the blocking column 2. At this time, the plug 102 and the blocking column 2 are quickly embedded in the inside of the glue inlet pipe 103 and the glue outlet pipe 104, and the inner wall of the scraper 201 fits with the inner wall of the glue inlet pipe 103 and the glue outlet pipe 104. At this time, the scraper 201 cannot be tilted and swung, and the inclination angle of the scraper 201 is 45°. The scraper 201 can form a closure on both ends of the glue inlet cavity 101 to prevent glue from overflowing into the inside of the glue inlet pipe 103 and the glue outlet pipe 104; When the plug is taken out from the inside of the glue inlet pipe 103 and the glue outlet pipe 104, one end of the scraper 201 rubs against the inner wall of the glue inlet pipe 103 and the glue outlet pipe 104, and slides toward one end of the scraper 201 by using the slider 301. The scraper 201 is now tilted 90° as a whole. The scraper 201 can scrape the glue on the inner wall of the glue inlet pipe 103 and the glue outlet pipe 104, so that this kind of sealing plug can form a seal inside the glue inlet structure after the glue is injected into the mold 1, avoiding the glue inside the mold 1 from overflowing. At the same time, after the sealing plug is taken out, the cured glue inside the glue inlet structure is scraped off.
