[0002] A plastic mold is a short name for a combined mold used for compression molding, extrusion molding, injection molding, blow molding, and low-foam molding; coordinated changes in the convex and concave dies and the auxiliary molding system of the mold can process a series of plastic parts with different shapes and sizes; when a plastic mold is processed, it needs to be fixed on an adjustable workbench of a machine tool, and the angle of the workbench can be adjusted according to processing requirements. The upper surface of the workbench is equipped with a set of T-shaped grooves that penetrate through both ends, which can conveniently install and fix various fixtures, measuring tools, and processing equipment. Currently, most of the adjustable workbench structures on the market are relatively simple. When processing plastic molds, the debris generated during processing will fall into the T-shaped grooves, and it is necessary for workers to clean them with a brush. Since the T-shaped grooves open upward and are narrow at the top and wide at the bottom, the debris in the bottom groove is difficult to be discharged by the brush and other tools, reducing the practicality of the device.

Detailed implementation manner

[0019] In order to enable those skilled in the art of this technology to better understand the solution of the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] The present invention will be further described below in conjunction with the embodiments.

[0021] Embodiment: Refer to Figure 1 , a positioning structure for a plastic mold with multi-angle adjustment, including a base 100 and a platen 200 rotatably mounted on the base 100. The base 100 and the platen 200 have corresponding rotary connection parts. By controlling the operating rod as in Figure 1 , the angle of the platen 200 can be adjusted, and the angle of the platen 200 can be fixed by bolts (not shown in the figure) on both sides of the base 100. This is a relatively mature technical means in the prior art and will not be elaborated here.

[0022] Refer to Figures 1 to 3, there is a set of T-shaped grooves 201 on the platen 200. A set of stoppers 300 are elastically arranged in the T-shaped grooves 201. Adjacent stoppers 300 are in contact with each other and the stoppers 300 are in contact with the inner wall of the T-shaped groove 201 to complete the occlusion of the T-shaped groove 201. The upper surface of the stopper 300 is aligned with the upper surface of the platen 200 in the initial state; by fitting a set of stoppers 300 in each T-shaped groove 201 to occlude the notch, foreign objects are prevented from entering the T-shaped groove 201 in the unused state; it also includes a T-shaped mounting block 400. The T-shaped mounting block 400 is adapted to the T-shaped groove 201 and has the same width as the stopper 300. The T-shaped mounting block 400 has a mounting bolt 401, and the mounting bolt 401 is used to cooperate with a nut; Specifically, when in use, all the stoppers 300 are pressed down, the T-shaped mounting block 400 is placed into the T-shaped groove 201 from the side of the T-shaped groove 201, the corresponding mounting holes on the fixture, such as, are sleeved on the mounting bolt 401 and fixed by cooperating with a nut. In the use state, the T-shaped mounting block 400 presses down the stopper 300 at the corresponding position and the upper part of the T-shaped mounting block 400 is aligned with the upper surface of the platen 200. By cooperating with other stoppers 300, the T-shaped groove 201 is partitioned, thereby preventing debris generated during the processing of the plastic mold from entering the T-shaped groove 201, facilitating the staff to clean the debris on the upper surface of the platen 200. The structure is simple, the operation is convenient, and the practicability of the device is improved.

[0023] It can be explained that several stoppers 300 are linearly arranged here. Since the T-shaped mounting block 400 needs to cooperate with the stopper 300 to occlude the T-shaped groove 201, the position of the T-shaped mounting block 400 is determined by the stopper 300. However, since the purpose of the T-shaped mounting block 400 is to fix the fixture acting on the plastic mold, and the base 100 in this device can also be installed on the linear module, the accuracy of the position of the T-shaped mounting block 400 will not be affected. Refer to Figures 2 to 3 , an installation groove 202 is opened at the bottom of the T-shaped groove 201. The installation groove 202 is used for the space for the baffle 505 to move down, that is, the stopper 300 moves down until its upper surface is flush with the bottom surface of the T-shaped groove 201, facilitating the insertion of the T-shaped mounting block 400 into the T-shaped groove 201. A positioning frame 500 is installed on the platen 200. The positioning frame 500 has a positioning plate 501 adapted to the installation groove 202. The positioning plate 501 is fixedly installed in the installation groove 202. The stopper 300 is installed on the positioning plate 501 through a first spring 502, facilitating the removal or installation of all the stoppers 300 on or off the platen 200.

[0024] Refer to Figures 1 to 3A telescopic sleeve 503 is installed on the positioning plate 501. The telescopic sleeve 503 provides a guide for the vertical movement of the baffle 505, so that the block 300 can move up and down stably, making it convenient for it to enter the upper opening of the T-slot 201 for blocking when resetting. The top of the telescopic sleeve 503 is threadedly connected to the block 300, which is convenient for the disassembly, assembly and replacement of the block 300.

[0025] Reference Figures 1 to 3 The width of the mounting groove 202 is less than or equal to the width of the upper groove of the T-slot 201 , so that the mounting frame can be installed from top to bottom through the T-slot 201 and installed in the mounting groove 202 .

[0026] Since there are multiple baffles 505, in order to facilitate the installation process of the T-shaped mounting block 400, that is, when the T-shaped mounting block 400 enters and exits the T-shaped slot 201, it is not necessary to press the elastically arranged baffles 300 one by one, a control mechanism 600 is further provided in the present application to control all baffles 300 to move up and down synchronously; Specifically, refer to Figures 2 to 7 The control mechanism 600 includes a linkage rod 602 that is interspersed with a second spring 601 and arranged on the block 300. The linkage rods 602 of all the blocks 300 maintain linear consistency, which facilitates the insertion of the linkage rod 602 into adjacent blocks 300, completes the series connection of all the blocks 300, and facilitates the control of all the blocks 300 to move downward. The two ends of the block 300 are vertically aligned with the two sides of all the blocks 300. The outer ends of the linkage rod 602 at both ends of the T-slot 201 protrude from the table 200, which facilitates the squeezing of the linkage rod 602 to first move horizontally linearly in series with the blocks 300, and then control all the blocks 300 to move downward.

[0027] Furthermore, there are two linkage rods 602 on each block 300 and they are symmetrically arranged in parallel. The linkage rods 602 have a rod path for the linkage rods 602 to move through. The upper sides of the opposite ends of the two linkage rods 602 respectively have a first inclined surface 603. The outer ends of the rod paths corresponding to the linkage rods 602 on the adjacent block 300 have a second inclined surface 604 corresponding to the first inclined surface 603. The first inclined surface 603 is in contact with the second inclined surface 604, which facilitates the resetting of the linkage rods 602 of the series-connected block 300 after the block 300 is reset, that is, after all the series-connected baffles 505 are moved downward, the linkage rods 602 can be released to automatically reset the linkage rods 602 on each block 300.

[0028] Further, the stopper 300 includes an upper block 301 and a lower block 302. A pair of first arc-shaped grooves 303 are respectively formed in the upper block 301 and the lower block 302. Two corresponding first arc-shaped grooves 303 are butted to form a rod passage for the linkage rod 602 to penetrate and move. Second arc-shaped grooves 304 are respectively formed in the middle parts of the upper block 301 and the lower block 302. The second arc-shaped grooves 304 are coaxial with the corresponding first arc-shaped grooves 303. A limiting block 605 is provided in the middle of the linkage rod 602. The second spring 601 is installed between the limiting block 605 and the inner wall of the first arc-shaped groove 303. By setting the stopper 300 as the upper block 301 and the lower block 302, it is convenient to install the second spring 601. Through the setting of the second spring 601, it is convenient for the linkage rod 602 to automatically reset after the action of the series-connected stopper 300 on the linkage rod 602 disappears.

[0029] Further, a through hole 305 is provided in the middle of the lower block 302. A threaded groove 306 is formed in the middle of the upper block 301. The threaded groove 306 is coaxial with the through hole 305. The top end of the telescopic sleeve 503 has a support block for supporting the lower block 302, and its top end has an external threaded portion 504 adapted to the threaded groove 306. During installation, the lower block 302 is placed on the support block, and then the upper block 301 is threadedly engaged with the external threaded portion 504, so that the upper block 301 and the lower block 302 can be fixed. The structure is simple and the installation is convenient.

[0030] Further, both sides of the T-shaped mounting block 400 have first vertical grooves 402 corresponding to the linkage rod 602. The upper ends of the first vertical grooves 402 do not protrude from the T-shaped mounting block 400, so as to avoid debris generated during the processing of the plastic mold from entering the T-shaped groove 201. The first vertical grooves 402 are used for the linkage rod 602 to move horizontally and then vertically. That is, after all the stoppers 300 are connected in series and moved down synchronously, when the linkage rod 602 on the stopper 300 at the outer end of the platen 200 is released, the T-shaped mounting block 400 does not affect the upward reset of the linkage rod 602. And because the T-shaped mounting block 400 will squeeze the corresponding stopper 300, correspondingly, the position of this stopper 300 remains fixed. That is, when other stoppers 300 move upward, under the combined action of the second inclined surface 604 and the second spring 601, the linkage rod 602 will also automatically reset, which is convenient for re-operation.

[0031] Further, baffles 505 are detachably arranged on both sides of the platen 200 to block the openings at both ends of the T-shaped groove 201, forming a structure that encloses the T-shaped groove 201 with the stoppers 300. Specifically, the baffle 505 only needs to block the side openings of the T-shaped groove 201 here and can be simply fixed by clamping or bolts. An operation bar 606 is arranged on the outer side of the baffle 505 to facilitate synchronously moving down the stoppers 300 in all the T-shaped grooves 201. A second vertical groove 506 corresponding to the first vertical groove 402 is opened on the baffle 505 to facilitate the downward movement of the linkage rod 602 when the T-shaped mounting block 400 is removed. The two linkage rods 602 on the stoppers 300 at both ends of the T-shaped groove 201 respectively pass through the corresponding second vertical grooves 506 and are fixed to the corresponding operation bars 606. By arranging two sets of linkage rods 602 on each stopper 300, it is convenient to control the series connection and downward movement of the baffles 505 from both sides of the platen 200, which is mainly reflected in the process of removing the T-shaped mounting block 400. Specifically, first remove the baffles 505 on both sides, and make all the stoppers 300 connected in series through the linkage rods 602 by horizontally pushing the operation bar 606, and then move them down. During this process, the part of the linkage rod 602 protruding from the stopper 300 on one side of the T-shaped mounting block 400 moves in the second vertical groove 506, facilitating the removal of the T-shaped mounting block 400 nearby. Correspondingly, for the T-shaped mounting block 400 close to the other side of the platen 200, by controlling the operation bar 606 on the other side, all the stoppers 300 outside the T-shaped mounting block 400 can be moved down and then removed.
