Description
Technical Field
[0001] The utility model belongs to the technical field of molds and relates to a bulletproof helmet mold with an inner sliding block for increasing the side pressure. Background Art
[0002] Most of the existing bulletproof helmets are molded by a molding die at one time. Since the core and cavity of the molding die are molded longitudinally from top to bottom, the top position of the helmet is completely molded by the core head, the molecular density at the top position is high, and the hardness is good. However, at the side position of the helmet, the lateral molding pressure of the core and the cavity on the side of the helmet is relatively small, so that the side of the helmet is not completely molded, resulting in low molecular density, poor hardness, and short service life of the helmet side. Since the core will be subjected to greater pressure during molding, the lateral boosting structure in the prior art mostly adopts boosting from the outside to the inside. The core is an integral part, and the problem of core damage will not occur. The present application proposes a core structure with high support performance, which can achieve lateral boosting from the inside to the outside.
[0003] For example, a Chinese patent discloses an injection molding edging mold, a molded edging production method and a bulletproof helmet [application number: 201810102197.8], wherein the injection molding edging mold can form a completely closed "U"-shaped injection molding cavity with the lower edge of the bulletproof helmet, and an injection molding machine is used to inject molten injection molding edging material into the "U"-shaped injection molding cavity to complete the edging, which can ensure that the injection molding edging material and the bulletproof helmet have a high bonding strength, so that the entire edging is seamlessly integrated with the helmet body.

[0027] In the utility model, the molding groove cooperates with the helmet bottom mold 4 to mold and form a bulletproof helmet. After completing the vertical molding, the lifting assembly can drive the middle insert 7 to move vertically, so that the side pressure insert 8 can be driven by the oblique guide structure to move horizontally outward to pressurize the side of the bulletproof helmet. After pressurization, the molecular density of the side of the helmet can be increased, thereby increasing the hardness and service life of the side of the helmet. When the movable mold plate 1 cooperates with the fixed mold plate for vertical molding, the top of the side pressure insert 8 can support the top insert 6, so that the lifting assembly will not be subjected to vertical downward pressure, thereby avoiding deformation of the combined helmet bottom mold 4.
[0028] Specifically, the bottom of the top insert 6 is a plane, and the tops of the middle insert 7 and the side pressure insert 8 are planes and can fit with the bottom of the top insert 6, and when the tops of the middle insert 7 and the side pressure insert 8 fit with the bottom of the top insert 6, they can be combined to form the helmet bottom mold 4. When the tops of the middle insert 7 and the side pressure insert 8 fit with the bottom of the top insert 6 and are combined to form the helmet bottom mold 4, the middle insert 7 and the side pressure insert 8 can jointly support the top insert, and since the side pressure block will not be displaced when receiving downward pressure, the lifting assembly that drives the middle insert to move vertically will not be subjected to downward pressure, thereby avoiding the problem of the middle insert retreating.
[0029] Specifically, a plurality of insert installation grooves 9 corresponding to the side pressure inserts 8 are arranged on the middle insert 7 along the circumferential direction, and the side pressure inserts 8 are arranged in the insert installation grooves 9, and there are four side pressure inserts 8. When the middle insert 7 is lifted or lowered in the vertical direction, the four side pressure inserts 8 can be driven to move synchronously in the horizontal direction.
[0030] Specifically, the oblique guide structure includes a guide slot 10 which is obliquely arranged in the middle position of the insert installation groove 9 and has a T-shaped cross section. A T-shaped guide block 11 inserted into the guide slot 10 is arranged in the middle position of the inner end of the side pressure insert 8. The guide slot 10 and the T-shaped guide block 11 are arranged vertically, and the spacing between the connecting surface of the guide slot 10 and the T-shaped guide block 11 and the outer edge of the helmet bottom mold 4 on the opposite side gradually increases from top to bottom. When the middle insert 7 moves vertically downward, the side pressure insert 8 can be driven to move horizontally outward. Since the spacing between the connecting surface of the guide slot 10 and the T-shaped guide block 11 and the outer edge of the helmet bottom mold 4 on the opposite side gradually increases from top to bottom, when the middle insert 7 moves vertically downward, the side pressure insert 8 can be pushed to move horizontally outward under the action of the guide slot 10 and the T-shaped guide block 11 to pressurize the side of the helmet.
[0031] Preferably, a plurality of vertical limiting rods 12 are provided on the fixed template 2, and the vertical limiting rods 12 penetrate the middle insert 7 from bottom to top and are fixedly connected to the top insert 6, and the middle insert 7 is slidably matched with the vertical limiting rods 12. The top insert can be fixed above the lateral insert by the plurality of vertical limiting rods 12, and the middle insert 7 is slidably matched with the vertical limiting rods 12 so that the middle insert can slide vertically and the vertical limiting rods can also limit the middle insert.
[0032] Specifically, there is a moving gap 13 between the vertical parting surface 18 at the connection between the side pressure insert 8 and the fixed mold plate 2 and the fixed mold plate 2 .
[0033] Preferably, combined Figure 5 As shown, a support seat 14 is provided at the lower side of the fixed template 2, the bottom of the side pressure insert 8 is supported on the support seat 14, and a sliding limit structure corresponding to the side pressure insert 8 is provided on the support seat 14, the lifting assembly is provided at the lower side of the support seat 14, and the sliding limit structure includes a limit slide 15 horizontally provided on the support seat 14, and a limit slider 16 is slidably matched in the limit slide 15, and the limit slider 16 is fixed to the bottom of the side pressure insert 8 by screws. The limit slide 15 cooperates with the limit slider 16 to limit the lateral insert to prevent the lateral insert from deflecting when moving.
[0034] Specifically, the lifting assembly includes a lifting driver 17 fixed to the bottom of the support base 14, and the output shaft of the lifting driver 17 passes through the support base 14 and is connected to the middle insert 7. The lifting driver can drive the middle insert to rise and fall in the vertical direction.
[0035] Those skilled in the art should understand that the lifting drive may be an oil cylinder, an air cylinder or a linear motor, etc.
[0036] The working principle of the utility model is as follows: the molding groove cooperates with the helmet bottom mold 4 to mold and form a bulletproof helmet. After completing the vertical molding, the lifting assembly can drive the middle insert 7 to move vertically, so that the side pressure insert 8 can be driven by the oblique guide structure to move horizontally outward to pressurize the side of the bulletproof helmet. After pressurization, the molecular density of the side of the helmet can be increased, thereby increasing the hardness and service life of the side of the helmet. When the movable mold plate 1 cooperates with the fixed mold plate for vertical molding, the top of the side pressure insert 8 can support the top insert 6, so that the lifting assembly will not be subjected to vertical downward pressure, thereby avoiding deformation of the combined helmet bottom mold 4;
[0037] When the top of the middle insert 7 and the side pressure insert 8 are attached to the bottom of the top insert 6 and combined to form the helmet bottom mold 4, the middle insert 7 and the side pressure insert 8 can jointly support the top insert. Since the side pressure block will not be displaced when receiving downward pressure, the lifting assembly that drives the middle insert to move vertically will not be subjected to downward pressure, thereby avoiding the problem of the middle insert retreating. When the middle insert 7 is lifted and lowered in the vertical direction, the four side pressure inserts 8 can be driven to move synchronously in the horizontal direction. Since the spacing between the connecting surface of the guide groove 10 and the T-shaped guide block 11 and the outer edge of the helmet bottom mold 4 on the opposite side gradually increases from top to bottom, when the middle insert 7 moves vertically downward, the side pressure insert 8 can be pushed to move horizontally outward under the action of the guide groove 10 and the T-shaped guide block 11 to pressurize the side of the helmet.
[0038] The top insert can be fixed above the lateral insert by a number of vertical limit rods 12, the middle insert 7 slides with the vertical limit rods 12 so that the middle insert can slide vertically and the vertical limit rods can also limit the middle insert, the limit slide groove 15 cooperates with the limit slider 16 to limit the lateral insert to prevent the lateral insert from shifting during movement, and the lifting drive can drive the middle insert to rise and fall in the vertical direction.
