DETAILED DESCRIPTION

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1: This embodiment is intended to promote the solution of the problem that in the prior art mold holding device, when clamping the mold, two clamping blocks, bolts and springs 220 are mostly used to directly rotate and clamp the mold. In the clamping process, due to the limited compression and extrusion force of the spring 220, the clamping of the mold may not be stable enough. Please refer to Figure 1-Figure 4A mold holding device includes a fixed base plate 110 and a mold body 210, a mold base plate 260 is fixedly installed in the middle of the fixed base plate 110, the mold body 210 is clamped and connected above the mold base plate 260, a first clamping block 120 is clamped and connected to one side of the mold body 210, a fixed block 130 is fixedly installed on the side of the first clamping block 120, and a clamping hole 170 is opened on the side of the first clamping block 120.

[0023] A connecting block 180 is snap-connected above the snap-fit ​​hole 170, a rotating pin 190 is fixedly installed in the middle of the connecting block 180, a handle 200 is fixedly connected to the side of the connecting block 180, a fixing plate 160 is fixedly installed on the side of the fixing block 130, the fixing plate 160 and the fixing block 130 are fixedly connected to the first snap-fit ​​block 120 via a fixing pin 140, and the side of the fixing plate 160 is fixedly installed to the fixing block 130 via a fixing bolt 150.

[0024] When the mold body 210 needs to be clamped and fixed, the staff can rotate the handle 200. When the staff rotates the handle 200, due to the fixed installation of the handle 200 and the connection block 180, the installation of the middle part of the connection block 180 and the rotating pin 190, when the handle 200 is rotated, the rotating pin 190 will drive the gear 230 fixedly installed at the bottom to rotate, thereby causing the gear 230 to rotate. When the gear 230 rotates, it will drive the first clamping block 120 to move on the fixed bottom plate 110, so that the first clamping block 120 squeezes the spring 220 to clamp the mold body 210. Due to the setting of the gear 230 and the rack 320, the elastic force of the spring 220 itself cannot push the first clamping block 120, thereby making the clamping of the mold body 210 more stable.

[0025] In this embodiment: when clamping the mold, the handle 200 can be manually controlled to drive the gear 230 to rotate, so that the gear 230 and the rack 320 are engaged, thereby driving the first clamping block 120 to move in the middle of the fixed base plate 110. When the first clamping block 120 moves, the spring 220 can be squeezed to clamp and fix the mold body 210, so that the clamping of the mold body 210 is more stable, which solves the problem that in the prior art mold holding equipment mentioned in the above background technology, when clamping the mold, two clamping blocks, bolts and springs 220 are mostly used for direct rotation clamping. Then, during the clamping process, due to the limited compression and extrusion force of the spring 220, the clamping of the mold may not be stable enough.

[0026] Embodiment 2: This embodiment is intended to promote the solution of the problem that in the prior art mold holding equipment, since some molds are made of soft materials, if the force is not controlled during clamping, it is very likely to cause the mold to deform. This embodiment is an improvement made on the basis of embodiment 1. For details, please refer to Figure 1-Figure 4 A mounting groove 330 is opened in the middle of the fixed base plate 110, and a gear 230 is rotatably mounted on the side of the mounting groove 330. The middle of the gear 230 is fixedly mounted with the rotating pin 190, and a rack 320 is meshed with the side of the gear 230. The rack 320 is fixedly mounted on the side of the mounting groove 330.

[0027] The other side of the fixed base plate 110 is engaged with a second engaging block 280, and a slide bar 250 is inserted in the middle of the second engaging block 280 and the first engaging block 120. A spring 220 is sleeved on the side of the slide bar 250. The slide bar 250 slides in the middle of the first engaging block 120 and the second engaging block 280. A limiting base plate 310 is fixedly installed on the side of the second engaging block 280. The limiting base plate 310 is fixedly installed with the second engaging block 280 by connecting bolts 290, and a fixing column 300 is inserted in the middle of the limiting base plate 310 and the second engaging block 280.

[0028] The first engaging block 120 and the second engaging block 280 are symmetrically arranged with the mold bottom plate 260 as the central axis, the sliding rod 250 and the spring 220 are symmetrically arranged with the mold bottom plate 260 as the central axis, a storage plate 240 is opened in the middle of the fixed bottom plate 110, and the mold bottom plate 260 is fixedly installed in the middle of the storage plate 240. When encountering mold bodies 210 of different materials, the staff can control the strength of the handle 200 to clamp it with appropriate strength, so as to avoid deformation of the mold body 210 due to the strong clamping force as much as possible.

[0029] In this embodiment: when the staff rotates the equipment, the rotation force can be adjusted according to the material and requirements of the mold by controlling the handle 200, so as to make the clamping of the mold body 210 more stable as much as possible. When the staff rotates the handle 200, the handle 200 will drive the connecting block 180 and the rotating pin 190 to rotate due to the fixed installation with the connecting block 180, thereby driving the gear 230 to rotate. At this time, the first clamping block 120 will clamp and fix the mold body 210 with the second clamping block 280. Through the staff's control of the force, different molds can be clamped with different forces as much as possible, thereby improving the qualification of the mold as much as possible.
