Description

Technical Field

[0001] This utility model relates to the technical field of bathroom heater production equipment, and in particular to an injection mold for producing bathroom heater panels. Background Technology

[0002] Injection molding, also known as injection molding, is a molding method that combines injection and molding. The advantages of injection molding include high production speed and efficiency, automated operation, a wide variety of designs and shapes (from simple to complex), and sizes ranging from large to small. It also produces dimensionally accurate products, facilitates product updates and replacements, and can create complex shapes. Injection molding is suitable for mass production and molding processes involving complex shapes.

[0003] When producing some box-shaped parts (such as the box of a bathroom heater), the upper and lower mold cores are usually set with matching molding convex and concave surfaces, which are then brought close together to form a cavity before injection molding. However, this injection molding method can only mold one bathroom heater box at a time, resulting in low production efficiency. Furthermore, if additional protrusions or hooks are needed on the side wall of the bathroom heater box, a second injection molding process is required, which is very troublesome. Summary of the Invention

[0004] In order to overcome the shortcomings of the existing technology, this utility model provides an injection mold for the production of bathroom heater panels.

[0005] The technical solution adopted by this utility model to solve its technical problem is:

[0010] As described above, in a type of injection mold for producing a bathroom heater housing, the upper mold assembly has accommodating grooves on both sides of the upper mold core that can accommodate the upper part of the slide block, and accommodating through slots on both sides of the upper mold core near the accommodating grooves that can accommodate the forming column.

[0011] As described above, in a type of injection mold for producing a bathroom heater housing, the receiving groove on the side away from the upper mold core is provided with a first guide slope, and the sliding block is provided with a second guide slope that can cooperate with the first guide slope.

[0012] As described above, in the injection mold for producing a bathroom heater housing, an auxiliary positioning structure is also provided between the upper mold core and the lower mold core.

By symmetrically arranged first and second molding recesses and matching first and second molding protrusions, the molding of two boxes can be completed in one injection molding, which greatly increases the production efficiency. At the same time, by matching the protrusion forming groove and the protrusion sliding position, the protrusion on the side wall of the box is formed simultaneously while the box is being formed. It is practical and convenient, and no further processing is required. Attached Figure Description

[0020] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0021] Please see Figures 1 to 4 As shown in the figure, this application provides an injection mold for producing a bathroom heater cabinet, including an upper mold assembly 1, a lower mold assembly 2, and an upper mold core 3 and a lower mold core 4 respectively disposed on the upper mold assembly 1 and the lower mold assembly 2. The upper mold core 3 is provided with a first forming recess 31 and a second forming recess 32 symmetrically arranged at its center. The lower mold core 4 is also provided with a first forming protrusion 41 and a second forming protrusion 42 symmetrically arranged at its center, which can respectively cooperate with the first forming recess 31 and the second forming recess 32 to form a cavity. The first forming recess 31 and the second forming recess 32 are also provided with a retaining groove 5 on the opposite side. The lower mold assembly 2 is also provided with retaining slides 6 on both sides of the lower mold core 4, which can respectively cooperate with the retaining groove 5 to form a cavity.

[0022] By using the symmetrically arranged first molding recess 31 and second molding recess 32, and the matching first molding protrusion 41 and second molding protrusion 42, the molding of two boxes 100 can be completed in one injection molding, greatly increasing production efficiency. At the same time, through the matching arrangement of the protrusion forming groove and the protrusion sliding position, the protrusion 101 on the side wall of the box is formed simultaneously while the box is being molded, which is practical and convenient, and no further processing is required.

[0023] Furthermore, the card protrusion slide 6 includes a slide block 61 and a forming post 62 protruding from the slide block 61. The forming post 62 can extend into the upper mold core 3 and cooperate with the card protrusion forming groove 5 to form.

[0024] During injection molding, when the upper mold core 3 and the lower mold core 4 close to form a cavity, the sliding block 61 moves synchronously, causing the innermost end of the forming pillar 62 to move to the lower end of the retaining forming groove 5 to cooperate in forming a retaining forming cavity, which is practical and convenient.

[0025] Specifically, the lower mold assembly 2 is provided with sliding grooves 20 on both sides of the lower mold core 4, and the sliding block 61 is slidably connected in the sliding grooves 20.

[0026] The bottom of both side walls of the slide groove 20 are also provided with limiting grooves 200, and the sliding block 61 is also provided with limiting flanges 610 that can be slidably embedded in the two limiting grooves 200 to maintain the stability of the sliding block 61.

[0027] Specifically, the upper mold assembly 1 is provided with receiving grooves 10 on both sides of the upper mold core 3, which can accommodate the upper part of the sliding block 61. The upper mold core 3 is also provided with receiving through grooves 30 on both sides near the receiving grooves 10, which can accommodate the forming column 62.

[0028] The receiving groove 10 is further provided with a first guide slope 71 on the side away from the upper mold core 3, and the sliding block 61 is further provided with a second guide slope 72 that can cooperate with the first guide slope 71. Through the cooperation of the first guide slope 71 and the second guide slope 72, when the upper mold core 3 moves down to close the mold, the sliding block 61 can be driven to slide and move the innermost end of the forming column 62 to the lower end of the retaining forming groove 5 to cooperate and form a retaining forming cavity, which is practical and convenient.

[0029] Furthermore, an auxiliary positioning structure 8 is provided between the upper mold core 3 and the lower mold core 4.

[0030] Specifically, the auxiliary positioning structure 8 includes a plurality of positioning concave surfaces 81 formed on the outer periphery of the upper mold core 3, and positioning ribs 82 protruding on the outer periphery of the lower mold core 4 and capable of cooperating with the corresponding positioning concave surfaces 81.

[0031] The combination of the positioning concave surface 81 and the positioning convex rib 82 ensures the stability of the mold closing of the upper mold core 3 and the lower mold core 4, making it practical and convenient.

[0032] In summary, the embodiments of this application, through the symmetrical arrangement of the first molding recess 31 and the second molding recess 32, and the matching arrangement of the first molding protrusion 41 and the second molding protrusion 42, enable the molding of two boxes in one injection, greatly increasing production efficiency. At the same time, through the matching arrangement of the protrusion forming groove and the protrusion sliding position, the protrusion on the side wall of the box is formed simultaneously while the box is being molded, which is practical and convenient, and requires no further processing.
