Abstract
Description
Technical Field
[0001] This utility model relates to the field of mold technology, specifically to a slanted top sleeve structure and mold that automatically compensates for machining errors in installation angle and position. Background Technology
[0002] An angled ejector is a mechanism used in mold design to form internal undercuts on a product. When undercuts appear on the inner surface of the product's sidewall, using an angled ejector is often a very effective method. During ejection, the angled ejector advances at a certain angle. This inclined movement provides both vertical ejection motion and lateral parting motion. The combination of these two movements allows the undercuts to disengage, thus enabling the product to be smoothly ejected.
[0003] Existing slanted ejector structures typically include a slanted ejector sleeve and a slanted ejector rod. The slanted ejector sleeve is fitted onto the end of the slanted ejector rod. In actual processing and installation, slanted ejector holes for mounting the slanted ejector rod are usually drilled in the template. Then, mounting positions for mounting the slanted ejector sleeve are machined at the ends of the slanted ejector holes. The slanted ejector holes and mounting positions need to be precisely fitted to the slanted ejector rod and slanted ejector sleeve, respectively. The high dimensional accuracy brings inconvenience to processing, especially for large molds such as car bumpers, where the slanted ejector holes on the slanted ejector sleeve are difficult to machine, and the machining accuracy is difficult to guarantee. If the machining accuracy is low, it will cause the slanted ejector to jam during later use, affecting the ejection effect of the product. Utility Model Content

[0032] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be described in detail below. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0033] Example 1:
[0034] This utility model provides a slanted top sleeve structure that automatically compensates for machining errors in installation angle and position. (Refer to...) Figures 1 to 9 As shown, the inclined top sleeve structure that automatically compensates for installation angle and positional machining errors includes an inclined top component 1 and an inclined top hole 21 that is provided through the template.
[0035] The inclined top assembly 1 is installed inside the inclined top hole 21; a compensation gap 22 is provided between the inclined top assembly 1 and the inner wall of the inclined top hole 21 to compensate for the machining errors of the installation angle and position.
[0036] During installation, firstly, a slanted ejector hole 21 is machined on the rear mold plate 2. Then, the slanted ejector assembly 1 is inserted into the slanted ejector hole 21, and the slanted ejector assembly 1 is connected to the ejector plate 4 on the rear mold base 3. During this process, since the slanted ejector hole 21 has a compensation gap 22, the slanted ejector assembly 1 can automatically adjust its installation angle and position. After the slanted ejector assembly 1 and the ejector plate 4 are connected, the slanted ejector assembly 1 and the rear mold plate 2 are connected.
[0037] In the aforementioned process, the compensation gap 22 can effectively compensate for the machining errors of the installation angle and position of the inclined top component 1. Therefore, the machining accuracy requirements of the inclined top hole 21 are lower, making production and processing more convenient.
[0038] During operation, after the mold is opened, the inclined ejector assembly 1 moves under the action of the ejector plate 4. Since the inclined ejector assembly 1 has a certain angle, it can simultaneously perform vertical ejection and horizontal lateral movement, thereby pushing the product to move, causing the undercut to disengage, and then smoothly ejecting it from the mold cavity.
[0039] In the aforementioned process, due to the existence of the compensation gap 22, the inclined top assembly 1 and the inclined top hole 21 are equivalent to a clearance fit, which reduces the machining accuracy requirements of the inclined top hole 21 and can effectively avoid the phenomenon of the inclined top jamming caused by insufficient machining accuracy of the inclined top hole, resulting in a significant ejection effect.
[0040] Example 2:
[0041] Example 2 is based on Example 1:
[0042] like Figures 1 to 9 As shown, the inclined top assembly 1 includes an inclined top rod 11 and an inclined top sleeve 12, and the inclined top hole 21 includes an inclined rod mounting hole 211 and an inclined sleeve mounting hole 212 connected in sequence.
[0043] The top end of the inclined push rod 11 passes through the inclined push sleeve 12 and the inclined rod mounting hole 211 in sequence. The inclined push sleeve 12 is used to guide the inclined push rod 11, and the inclined push rod 11 is used to push the inclined push block 13 to move.
[0044] The inclined top sleeve 12 is set inside the inclined sleeve mounting hole 212; a first gap 221 is provided between the inclined top rod 11 and the inner wall of the inclined rod mounting hole 211, and a second gap 222 is provided between the inclined top sleeve 12 and the inner wall of the inclined sleeve mounting hole 212. The first gap 221 and the second gap 222 are connected to form a compensation gap 22.
[0045] Specifically, the size of the compensation gap 22 is 0.5 to 1 mm.
[0046] During the installation of the inclined top assembly 1 and the ejector plate 4, due to the existence of the compensation gap 22, the inclined top sleeve 12 and the inclined top rod 11 automatically and adaptively adjust their position and angle as the connection is made. After the connection is completed, the inclined top assembly 1 and the rear template 2 are then connected.
[0047] This design significantly reduces the precision requirements for machining the inclined top hole 21, thus facilitating machining.
[0048] As an optional implementation, the inclined top hole 21 includes a top block mounting hole 213, and the inclined top assembly 1 includes an inclined top block 13.
[0049] The inclined sleeve mounting hole 212, the inclined rod mounting hole 211, and the top block mounting hole 213 are connected in sequence. The top block mounting hole 213 is opened on the top side of the rear template 2. The top end of the inclined top rod 11 is inserted into the top block mounting hole 213 and connected to the inclined top block 13.
[0050] The inclined ejector block 13 is an actuator used to push the product, and it comes into direct contact with the product during the ejection process.
[0051] The shape and specific structure of the inclined top block 13 are not limited and can be set according to the actual product.
[0052] As an optional implementation, the inclined top sleeve 12 includes a mounting platform 122 and a main body section 121 disposed on the first side of the mounting platform 122. The inclined sleeve mounting hole 212 includes a first mounting hole section and a second mounting hole section. The first mounting hole section and the second mounting hole section are respectively adapted to the main body section 121 and the mounting platform 122. The main body section 121 and the mounting platform 122 are respectively located in the first mounting hole section and the second mounting hole section.
[0053] The mounting platform 122 is the installation structure for the inclined top sleeve 12 and the rear template 2. After the inclined top assembly 1 and the ejector plate 4 are connected, the mounting platform 122 and the rear template 2 are connected.
[0054] As an optional implementation, the mounting plate 122 is provided with a fixing hole for installing the first threaded fastener 14, and a positioning hole for installing the positioning pin 15.
[0055] During installation, after the inclined top assembly 1 is connected to the ejector plate 4, a first opening and a second opening are respectively set on the rear template 2 at the positions corresponding to the fixing hole and the positioning hole. Then, the positioning pin 15 is passed through the positioning hole and inserted into the second opening, and the first threaded fastener 14 is passed through the fixing hole and connected to the first opening.
[0056] As an optional implementation, the inclined top sleeve 12 includes an extension section 123 disposed on the second side of the mounting platform 122. The main body section 121, the mounting platform 122 and the extension section 123 are coaxially disposed and integrally formed. The extension section 123 is located outside the inclined top hole 21.
[0057] The extension section 123 is designed to improve the guiding effect of the inclined ejector sleeve 12 on the inclined ejector rod 11. Its length is set according to the mold space.
[0058] As an optional implementation, the inclined top assembly 1 includes a guide sleeve 16, and the end of the inclined top sleeve 12 is provided with a mounting groove 124 that matches the shape of the guide sleeve 16. The guide sleeve 16 is disposed in the mounting groove 124, and the inclined top rod 11 passes through the guide sleeve 16.
[0059] Specifically, both ends of the inclined top sleeve 12 are provided with mounting grooves 124, and the number of guide sleeves 16 is set to two, which are respectively set in the corresponding mounting grooves 124.
[0060] The two guide sleeves 16 located at both ends cooperate with each other to provide a longer guiding distance, thereby effectively preventing the inclined push rod 11 from breaking or bending.
[0061] As an optional implementation, the guide sleeve 16 is detachable within the mounting slot 124 via the mounting assembly 17.
[0062] Specifically, the mounting assembly 17 includes a second threaded fastener 171 and a pressure ring 172. The second threaded fastener 171 passes through the pressure ring 172 and is connected to the end face of the inclined top sleeve 12, thereby causing the pressure ring 172 to press the guide sleeve 16 into the mounting groove 124.
[0063] The guide sleeve 16 is easy to install and remove due to its threaded press-fit installation method.
[0064] As an optional implementation, the inclined ejector assembly 1 includes an inclined ejector seat 18, the bottom end of the inclined ejector rod 11 is disposed on the inclined ejector seat 18, and the inclined ejector seat 18 is connected to the ejector plate 4 on the rear mold base 3.
[0065] Cooling pipes are installed axially inside the inclined push rod 11.
[0066] Specifically, the inclined push rod 11 has a cavity along the axial direction, and a cooling copper pipe 19 is provided in the cavity. The internal pipe of the cooling copper pipe 19 is a first cooling pipe, and the outer wall of the cooling copper pipe 19 and the cavity wall of the cavity form a second cooling pipe. The first cooling pipe and the second cooling pipe are connected. The bottom end of the cooling copper pipe 19 is located outside the inclined push rod 11 and is connected to a pipe joint.
[0067] The cooling pipes effectively cool the inclined top assembly 1, preventing it from overheating and affecting the ejection effect.
