Description

Technical Field

[0001] The utility model belongs to the technical field of mold bases, and particularly relates to a mold base with an external pull rod. Background Art

[0002] A mold frame refers to the mold's support or support system, used to support and secure the mold for stable use. Commonly used in industrial production, mold frames help ensure the mold maintains optimal position and condition during production. They typically consist of an ejector mechanism, guides, a pre-reset mechanism, mold foot pads, and a base plate. The mold frame is a semi-finished product of the mold, constructed from a variety of steel plates and components. It can be considered the skeleton of the entire mold. Due to the significant differences in the processing involved in mold frames and molds, mold manufacturers often choose to order mold frames from mold frame manufacturers, leveraging the production strengths of both parties to improve overall production quality and efficiency.

[0003] The mold base with external tie rods in the prior art has the following disadvantages during use:

[0004] Most mold frames require manual fixation of the mold to the mold frame base through bolts and other fixing structures, which makes the disassembly and assembly of the mold very inconvenient. There is a lack of a structure that can actively fix the mold when it is pushed into the mold frame, which greatly reduces the disassembly and assembly efficiency between the mold and the mold frame. Therefore, a mold frame with an external pull rod is needed. Utility Model Content

[0005] The purpose of the present utility model is to provide a mold base with an external tie rod to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solution: a mold frame with an external pull rod, comprising a mold frame base, the top end of the mold frame base is slidably connected to a bottom plate, the middle portion of the bottom end of the bottom plate is fixedly connected to a sliding seat with a convex vertical cross-section, the sliding seat is slidably connected to a sliding groove provided at the top end of the mold frame base, the front end of the sliding seat is fixedly connected to the external pull rod, the front end of the external pull rod movably passes through the front side of the mold frame base, and is fixedly connected to a pull block;

[0007] It also includes an active loosening and clamping structure and a locking and anti-movement structure, wherein the active loosening and clamping structure is installed at the top of the mold base and connected to the top of the bottom plate, and the locking and anti-movement structure is installed on the front side wall of the mold base and connected to the left end of the pull block;

[0008] The active loosening structure can actively clamp the mold when the outer pull rod pushes the bottom plate to move the mold placed on it inward. Conversely, when the bottom plate is pulled to move the mold placed on it outward, the clamping of the mold can be actively removed.

[0009] The locking and anti-movement structure can fix the position of the pull block to prevent the base plate from moving outward during processing.

[0010] As a preferred embodiment, the active loosening structure includes a positioning block fixed in the middle of the top of the base plate and close to the rear side wall of the mold base. Side clamps are provided on both sides of the positioning block and are slidably connected to the top of the base plate. The two side clamps are symmetrically arranged.

[0011] As a preferred embodiment, the bottom ends of the side clamps are fixedly connected with sliders with convex vertical cross-sections, and the sliders are slidably connected to the sliding grooves provided at the top of the bottom plate.

[0012] As a preferred embodiment, connecting rods are fixed to the side walls of the two side splints facing away from each other, the bottom ends of the connecting rods are fixed to transmission columns, and the bottom ends of the transmission columns are movably connected to the guide channels provided at the top of the mold base.

[0013] As a preferred embodiment, the locking and anti-movement structure includes an L-shaped block slidably connected to the front side wall of the mold base, and a push column is fixed to the front side wall of the L-shaped block.

[0014] As a preferred embodiment, one end of the L-shaped block is fixedly connected to a guide block with a convex vertical cross-section. The guide block is slidably connected to the guide groove provided on the front side wall of the mold base. The inclined surface provided at the other end of the L-shaped block is movably connected to the groove provided on the left end of the pull block. The end of the guide block facing away from the outer pull rod is fixedly connected to the inner wall of the guide groove through a spring.

[0015] Compared with the prior art, the mold base with external tie rods provided by the present invention has at least the following beneficial effects:

[0016] In the present invention, when the mold frame is used, when the mold on the base plate needs to be replaced, the push column can be used to push the L-shaped block to the left, and the guide block compresses the spring, so that the inclined end of the L-shaped block is disengaged from the left end slot of the pull block. At this time, the sliding seat connected to the outer pull rod can be pulled outward by the pull block, so that the base plate moves outward. During the movement, both transmission columns move in the guide channel. Due to the shape setting of the guide channel, the bottom plate moves outward at the end, and the setting of the connecting rod is cooperated with the setting of the connecting rod, the two side clamps can move away from each other, thereby facilitating the removal of the clamping action of the mold on the base plate, thereby facilitating the rapid replacement of the mold, greatly improving the efficiency of disassembly and assembly, and cannot be manually fixed by fixing structures such as bolts. In addition, the setting of the L-shaped block effectively prevents the mold frame from moving after pressing the mold, greatly improving the stability during pressing, and avoiding damage to the mold caused by displacement.

[0022] The present invention will be further described below with reference to the embodiments.

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings of the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all the embodiments. Based on the described 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.

[0024] The following examples are intended to illustrate the present invention and are not intended to limit the scope of protection of the present invention. The conditions in the examples may be further adjusted according to specific conditions. Simple improvements to the method of the present invention based on the concept of the present invention fall within the scope of protection claimed by the present invention.

[0025] Example

[0026] Most mold frames require manual fixing of the mold to the mold frame base 1 using bolts or other fixing structures, which makes the mold very inconvenient to disassemble and assemble. There is no structure that can automatically fix the mold when it is pushed into the mold frame, which greatly reduces the efficiency of disassembly and assembly between the mold and the mold frame.

[0027] To do this, see Figure 1-4The utility model provides a mold frame with an external tie rod, comprising: a mold frame base 1, the top of the mold frame base 1 is slidably connected to a bottom plate 2, a sliding seat 21 with a convex vertical cross-section is fixedly connected to the middle of the bottom end of the bottom plate 2, the sliding seat 21 is slidably connected to a sliding groove provided at the top of the mold frame base 1, the front end of the sliding seat 21 is fixedly connected to an external tie rod 22, the front end of the external tie rod 22 movably passes through the front side of the mold frame base 1, and is fixedly connected to a pull block 23;

[0028] It also includes an active loosening structure 3 and a locking anti-movement structure 4. The active loosening structure 3 is installed on the top of the mold base 1 and is connected to the top of the bottom plate 2. The locking anti-movement structure 4 is installed on the front side wall of the mold base 1 and is connected to the left end of the pull block 23.

[0029] The active loosening structure 3 can actively clamp the mold when the outer pull rod 22 pushes the bottom plate 2 to move the mold placed thereon inward. Conversely, when the bottom plate 2 is pulled to move the mold placed thereon outward, the clamping of the mold can be actively removed.

[0030] The locking and anti-movement structure 4 can fix the position of the pull block 23 to prevent the bottom plate 2 from moving outward during processing.

[0031] Further as Figure 1-4 As shown, it is worth mentioning that in order to be able to actively clamp and fix the mold when the base plate 2 drives the mold to move toward the inside of the mold frame, an active loosening structure 3 is set, including a positioning block 31 fixed at the middle of the top of the base plate 2 and close to the rear side wall of the mold frame base 1. Both sides of the positioning block 31 are provided with side clamps 32 slidably connected to the top of the base plate 2. The two side clamps 32 are symmetrically arranged. The bottom ends of the side clamps 32 are fixed with sliders 33 with convex vertical cross-sections. The sliders 33 are slidably connected to the slide grooves provided at the top of the base plate 2. Connecting rods 34 are fixed on the side walls opposite to each other of the two side clamps 32. The bottom ends of the connecting rods 34 are fixed with transmission columns 35. The bottom ends of the transmission columns 35 are movably overlapped in the guide channels 36 provided at the top of the mold frame base 1.

[0032] The shape of the guide channel 36 is as shown in the attached figure. Figure 3 As shown in the figure, when the bottom plate 2 moves toward the inside of the mold frame, the two side clamps 32 can actively clamp and fix the mold. At the same time, the positioning block 31 can facilitate the positioning of the placed mold to avoid front and rear position offset and affect the pressing of the mold frame. In addition, the bottom end diameter of the transmission column 35 is equal to the width of the guide channel 36 to prevent the side clamps 32 from shaking left and right.

[0033] Further as Figure 1-4As shown, it is worth mentioning that in order to be able to clamp and fix the pull block 23, a locking and anti-movement structure 4 is set, which includes an L-shaped block 41 slidably connected to the front side wall of the mold base 1, and a push column 45 is fixed to the front side wall of the L-shaped block 41. One end of the L-shaped block 41 is fixed with a guide block 42 with a convex structure in vertical section. The guide block 42 is slidably connected to the guide groove provided on the front side wall of the mold base 1, and the inclined surface provided at the other end of the L-shaped block 41 is movably clamped in the slot 43 provided on the left end of the pull block 23. The end of the guide block 42 facing away from the outer pull rod 22 is fixed to the inner wall of the guide groove through a spring 44.

[0034] Among them, the inclined surface set at the other end of the L-shaped block 41 is not completely clamped in the slot 43, but a part of it is exposed outside, so that after the pull block 23 pushes the outer pull rod 22, the left end of the pull block 23 can actively squeeze one end of the inclined surface, thereby facilitating active clamping in the slot 43. When the base plate 2 needs to be pulled out, the L-shaped block 41 needs to be pushed to the left through the push column 45.

[0035] In summary: when using the mold frame, when the mold on the bottom plate 2 needs to be replaced, the L-shaped block 41 can be pushed to the left by the push column 45, and the guide block 42 compresses the spring 44, so that the inclined end of the L-shaped block 41 is disengaged from the left end slot 43 of the pull block 23. At this time, the sliding seat 21 connected to the outer pull rod 22 can be pulled outward by the pull block 23, so that the bottom plate 2 moves outward. During the movement, the two transmission columns 35 move in the guide channel 36. Since the guide channel 36 The shape setting makes the bottom plate 2 move outward at the end, and the setting of the connecting rod 34 allows the two side clamping plates 32 to move away from each other, thereby facilitating the removal of the clamping action on the mold on the bottom plate 2, thereby facilitating the rapid replacement of the mold, greatly improving the efficiency of disassembly and assembly, and it is impossible to use bolts and other fixing structures for manual operation and fixation. In addition, the setting of the L-shaped block 41 effectively prevents the bottom plate 2 from moving after the mold frame presses the mold, greatly improving the stability during pressing, and avoiding damage to the mold caused by displacement.
