Description

Technical Field

[0001] This utility model relates to the field of injection molding machine technology, specifically to an injection molding machine template structure. Background Technology

[0002] Injection molding machines are the main molding equipment used to make various shapes of plastic products from thermoplastic or thermosetting plastics using plastic molds. The mold plate is one of the key components of the injection molding machine, and it bears huge clamping force and injection pressure during the injection process. At present, the existing injection molding machine mold plate structure has some shortcomings.

[0003] Based on the above, the inventors have discovered the following problems: the current injection molding machine templates do not have a rapid heat dissipation function during use. Due to the heat transfer of the plastic melt, the template temperature will rise, thereby affecting the service life of the template and the molding accuracy of the plastic products.

[0004] Therefore, in view of this, we have studied and improved the existing structure and its shortcomings, and provided an injection molding machine template structure in order to achieve a more practical value. Utility Model Content

[0005] The purpose of this utility model is to provide an injection molding machine template structure to solve the problem mentioned in the background art that the current injection molding machine templates do not have a rapid heat dissipation function during use. Due to the heat transfer of the plastic melt, the template temperature will rise, thereby affecting the service life of the template and the molding accuracy of the plastic products.

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

[0007] An injection molding machine template structure includes a base plate, a template body mounted on the top of the base plate, a top plate at the top of the template body, a mold groove at the top of the template body, several heat dissipation holes at one bottom side of the template body, an injection hole at the center of the top of the top plate, a ventilation mechanism mounted on one bottom side of the template body, the ventilation mechanism including a connecting pipe, one side of the connecting pipe connected to one end of the heat dissipation holes, an exhaust fan mounted on the top of the connecting pipe, an exhaust pipe mounted on the top of the connecting pipe, one end of the exhaust pipe connected to the input end of the exhaust fan, and auxiliary lifting mechanisms for connecting the top plate are mounted on both sides of the top of the base plate.

[0008] Furthermore, the auxiliary lifting mechanism includes a frame, the bottom end of which is fixedly connected to the top end of the base plate. Slide rods are installed at both ends of the interior of the frame, and sliders are slidably connected to both ends of the slide rods. A first connecting seat is installed at the top end of the slider. A connecting rod is rotatably connected to one end of the first connecting seat, and a second connecting seat is rotatably connected to one end of the connecting rod. The top end of the second connecting seat is fixedly connected to the bottom end of the top plate.

[0009] The beneficial effect of adopting the above-mentioned further solution is that, by having sliders slidably connected to both ends of the slide rod, the sliders move along the slide rod when the top plate is raised or lowered, thus sharing the weight of the top plate through the lever principle, reducing wear between the template body and the top plate, and improving the stability of mold opening and closing.

[0010] Furthermore, springs are fitted at both ends of the slide rod, with one end of the spring fixedly connected to one end of the frame and the other end of the spring fixedly connected to one side of the slider.

[0011] The beneficial effect of adopting the above-mentioned further solution is that by sleeved with springs at both ends of the slide rod, an elastic force is applied to the slider. When the top plate descends, the springs compress and store energy, and when the top plate rises, the springs release energy to assist in the lifting, thereby reducing the load on the hydraulic system.

[0012] Furthermore, the outer side of the slider is slidably connected to the inner wall of the frame.

[0013] The beneficial effect of adopting the above-mentioned further solution is that by sliding the outer side of the slider and the inner wall of the frame, the movement trajectory of the slider is restricted, thereby improving the movement stability of the slider.

[0014] Furthermore, the heat dissipation holes are distributed at equal intervals.

[0015] The beneficial effect of adopting the above-mentioned further solution is that, by distributing several heat dissipation holes at equal intervals, the ventilation mechanism can evenly cover the entire template.

[0016] Furthermore, a guide vane is installed on the inner side of the heat dissipation through hole, and the guide vane is in a spiral shape.

[0017] The beneficial effect of adopting the above-mentioned further solution is that the guide vanes installed on the inner side of the heat dissipation holes can guide the airflow to form a spiral flow, prolong the contact time between the airflow and the template body, enhance the heat exchange efficiency, and at the same time, the spiral airflow can agitate the hot air inside the template, break the air laminar flow boundary, and make the heat more efficiently discharged by the exhaust fan, further improving the heat dissipation effect.

[0018] Furthermore, the bottom plate has a first fixing hole at each of the four corners of its top end, and the top plate has a second fixing hole at each of the four corners of its bottom end.

[0019] The beneficial effect of adopting the above-mentioned further solution is that the template structure is fixed to the frame of the injection molding machine by setting the first fixing hole and the second fixing hole for installing bolts.

[0020] Compared with the prior art, the beneficial effects of this utility model are as follows: The injection molding machine template structure, through the setting of the base plate, provides basic support for the template structure. The template body and the top plate constitute the core space for injection molding. The mold groove is used to accommodate the mold and form the shape of the injection molded product. The heat dissipation holes cooperate with the ventilation mechanism. The exhaust fan extracts heat from the template body through the connecting pipe and the exhaust pipe, reducing the mold temperature and preventing the plastic melt from deforming due to high temperature, thus improving the product molding accuracy. The auxiliary lifting mechanism can assist in the lifting and lowering of the top plate, reducing frictional resistance during mold opening and closing, and improving the stability of equipment operation. Sliding blocks are slidably connected to both ends of the sliding rod, so that when the top plate is lifted or lowered, the sliding blocks move along the sliding rod, distributing the weight of the top plate through the lever principle, reducing wear between the template body and the top plate, and improving the smoothness of mold opening and closing. Springs are sleeved on both ends of the sliding rod to apply elastic force to the sliding blocks. When the top plate descends… The spring compresses and stores energy; when the top plate rises, the spring releases energy to assist in the lifting, reducing the load on the hydraulic system. The sliding connection between the outer side of the slider and the inner wall of the frame restricts the slider's movement trajectory, improving its stability. The evenly spaced distribution of several heat dissipation holes ensures the ventilation mechanism evenly covers the entire template. Guide vanes installed inside the heat dissipation holes guide the airflow into a spiral flow, extending the contact time between the airflow and the template body and enhancing heat exchange efficiency. Simultaneously, the spiral airflow agitates the hot air inside the template, breaking the laminar flow boundary and allowing heat to be more efficiently expelled by the exhaust fan, further improving heat dissipation. The first and second fixing holes are used for mounting bolts to fix the template structure to the injection molding machine frame. This invention effectively achieves air-cooling heat dissipation, preventing heat accumulation inside the template and possessing high practical value. Attached Figure Description

[0032] Please see Figures 1-5A number of heat dissipation holes 202 are evenly spaced, and guide vanes 203 are installed on the inner side of the heat dissipation holes 202. The guide vanes 203 are spiral in shape. The top four corners of the bottom plate 1 are provided with first fixing holes 101, and the bottom four corners of the top plate 3 are provided with second fixing holes 301. By distributing the heat dissipation holes 202 at equal intervals, the exhaust effect of the ventilation mechanism 4 can evenly cover the entire template. The guide vanes 203 installed on the inner side of the heat dissipation holes 202 can guide the airflow to form a spiral flow, prolong the contact time between the airflow and the template body 2, and enhance the heat exchange efficiency. At the same time, the spiral airflow can agitate the hot air in the template, break the air laminar flow boundary, and make the heat more efficiently discharged by the exhaust fan 403, further improving the heat dissipation effect.

[0033] Specifically, the working principle of this injection molding machine template structure is as follows: During use, the base plate 1 provides basic support for the template structure. The template body 2 and the top plate 3 constitute the core space for injection molding. The mold groove 201 accommodates the mold and forms the shape of the injection molded product. The heat dissipation hole 202 cooperates with the ventilation mechanism 4. The exhaust fan 403 extracts heat from the template body 2 through the connecting pipe 401 and the exhaust pipe 402, reducing the mold temperature and preventing the plastic melt from deforming due to high temperature, thus improving the product molding accuracy.

Sliding blocks 503 are slidably connected to both ends of the sliding rod 502, so that when the top plate 3 is lifted or lowered, the sliding blocks 503 move along the sliding rod 502, sharing the weight of the top plate through leverage, reducing wear between the template body 2 and the top plate 3, and improving the smoothness of mold opening and closing. Springs 504 are sleeved on both ends of the sliding rod 502, applying elastic force to the sliding blocks 503. When the top plate 3 descends... When the spring 504 is compressed and stored, it releases energy to assist in the lifting when the top plate 3 rises, reducing the load on the hydraulic system. The sliding connection between the outer side of the slider 503 and the inner wall of the frame 501 restricts the movement trajectory of the slider 503 and improves the movement stability of the slider 503. The ventilation mechanism 4 can evenly cover the entire template by distributing several heat dissipation holes 202 at equal intervals. The guide plate 203 installed on the inner side of the heat dissipation hole 202 can guide the airflow to form a spiral flow, prolonging the contact time between the airflow and the template body 2 and enhancing the heat exchange efficiency. At the same time, the spiral airflow can agitate the hot air inside the template, break the air laminar flow boundary, and make the heat more efficiently discharged by the exhaust fan 403, further improving the heat dissipation effect.
